एक वैज्ञानिक जो अपनी मौत के 18 साल बाद हो गया महान

एक वैज्ञानिक जो अपनी मौत के 18 साल बाद हो गया महान / 18 years after his death He Became A Great Scientist

महान वैज्ञानिक ग्रेगर जॉन मेंडल  :

कौन : ग्रेग्रर जॉन मेंडल

क्या : आधुनिक आनुवंशिकी जगत का पितामहकब :जन्म 20 जुलाई 1822 , निधन : 6 जनवरी 1884

उथल-पुथल से भरा जीवन

विज्ञान को एक नई दिशा देने वाले मेंडल का जीवन उथल-पुथल से भरा था।

जी हां ग्रेग्रर जॉन मेंडल ने अपने उस अध्यापक की बात को सच करके दिखा दिया था जिन्होंने मेंडल की प्रतिभा को 11 साल की उम्र में पहचान लिया था और मेंडल के माता पिता से कहा था कि यह बालक बेहद प्रतिभावान है और इसे उच्च शिक्षा मिलनी ही चाहिए। हालांकि मेंडल के माता पिता की आर्थिक स्थिति अच्छी नहीं थी लेकिन तमाम संघर्षो से गुजरते हुए मेंडल ने वह कर दिखाया था जिसने विज्ञान जगत के भविष्य की दिशा तय कर दी थी और उनकी आनुवंशिकी के नियमों की खोज ने उनको विज्ञान में अमर बना दिया था लेकिन अफसोस मेंडल के जीते जी विज्ञान जगत उनके नियमों को समझ नहीं पाया था और उनके मरने के 18 साल बाद संसार का वैज्ञानिक समुदाय को जब पता चला कि मेंडल ने वह कर दिखाया है जो उनको लगभग भगवान का दर्जा देने के बराबर था। जीव का निर्माण आखिर कैसे होता है और कोई व्यक्ति आखिर विशेष गुणों के साथ कैसे जन्म लेता है? हम अपने माता पिता की तरह किस तरह अपने गुणों से मेल खाते है लगभग हर बात का जवाब उनकी खोज में था लेकिन विज्ञान जगत ने इसे समझने में देर कर दी थी। अगर उस समय के प्रसिद्ध वैज्ञानिक कार्ल नेगेली मेंडल के नियमों को मान्यता दे देते तो विज्ञान जगत न केवल 18 साल आगे हो जाता बल्कि मेंडल जीते जी अपनी ख्याती और अपनी खोज को मान्यता मिलते हुए देख लेते जिसके लिए उन्होंने कड़ी मेहनत की थी।

क्या कहा था प्रोफेसर नेगेली ने

मेंडल अपने समय के सुविख्यात जीवविज्ञानी प्रोफेसर कार्ल नेगेली से अपने कार्य की मान्यता लेना चाहते थे। इसके लिए उन्होंने अपना शोध निबंध नेगेली को भेजा। नेगेली ने पहले तो जवाब नहीं दिया, परंतु जब मेंडल लगातार पत्र लिखते रहे तो उन्होंने जवाब भेजा। नेगेली ने लिखा था कि जो सीजर का है, सीजर को दो और जो भगवान का है भगवान को दो। मैं नहीं जानता कि आप वनस्पतिशास्त्री हैं या गणितज्ञ यदि आप वनस्पतिशास्त्री हैं तो वनस्पतियों पर अध्ययन कीजिए और अगर आप गणितज्ञ हैं तो पौधों पर संकरण करने से बाज आइए।
-------------------------------------------------------
मेंडल को था खुद पर यकीन

यह जीव विज्ञान का दुर्भाग्य ही है कि मेंडल का सारा श्रम 37 वर्षो तक पुस्तकालयों में धूल बटोरता रहा और किसी ने उसपर ध्यान नहीं दिया। लेकिन मेंडल अपने शोधकार्यो से पूरी तरह संतुष्ट थे। जीवन के अंतिम सालों में उन्होंने लिखा था कि अपने वैज्ञानिक कार्यो से मैं बहुत संतुष्ट हूं और मुझे पूरा विश्वास है कि शीघ्र ही पूरी दुनिया मेरे काम को सराहेगी। वे बातचीत में अपने शिष्यों से कहा करते थे कि एक दिन उनका समय आएगा, जरूर आएगा।

------------------------------------------
मौत के बाद चर्चित हुए मेंडल

मेंडल को प्रसिद्धि मौत के 18 साल के बाद मिली। 1902 में एक ही शोध पत्रिका में तीन विभिन्न देशों के वैज्ञानिकों के शोध निबंध प्रकाशित हुए। ये वैज्ञानिक थे हॉलैंड के प्रसिद्ध वनस्पतिशास्त्री ह्यूगो डी व्रिज, जर्मनी के कार्ल कॉरेंस और आस्ट्रिया के एरिक वॉन। आश्चर्यजनक रूप से तीनों निबंध आनुवांशिकता के उन्हीं बुनियादी और मात्रात्मक नियमों के बारे में थे जिसके बारे में ग्रिगोर मेंडल 37 वर्ष पहले ही लिख चुके थे। इन तीनों वैज्ञानिकों ने मेंडल के आनुवंशिकता के नियमों को स्वतंत्र रूप से दोबारा खोज निकाला था। जिसके बाद मेंडल पुनर्जीवित हो उठे थे।
---------------------------------------------------------------
मेंडल जीव विज्ञान में फेल हो गए थे

जी हां जीव विज्ञान की नई शाखा आनुवांशिकी के जनक कहे जाने वाले ग्रिगोर मेंडल जीव विज्ञान में फेल हो गए थे। यह बात है 1850 की, जब मेंडल ने स्थायी शिक्षक बनने के लिए वियना विश्वविद्यालय द्वारा आयोजित एक परीक्षा में भाग लिया था। उन्होंने भौतिकी और अन्य विषयों की परीक्षा दी, परंतु वे इसमें फेल हो गए। यह विडंबना ही है कि सबसे कम अंक उन्हें जीव विज्ञान में ही मिले थे।
-----------------------------------------------------------
बहन के दहेज के जुटाए पैसों से की पढ़ाई

मेंडल का पूरा जीवन संघर्ष में बीता। उनके पिता किसान थे। स्कूल के दिनों में मेंडल टच्यूशन कर अपने खर्च का इंतजाम करते थे। जब वे कॉलेज जाने के लायक हुए तो दुर्भाग्य से उसी समय उनके पिता की मौत हो गई। उनके परिवार पर संकट का पहाड़ टूट पड़ा। पिता ने अपनी खेती और सारा कारोबार बड़ी बेटी और दामाद को सौंप दिया था। जब मेंडल ने अपनी बहन, बहनोई से मदद मांगी तो उन्होंने मुंह फेर लिया। ऐसे समय में उनकी छोटी बहन तेरेजिया ने अपने दहेज के लिए जुटाए गए धन में से कुछ रुपए देकर मेंडल की मदद की और उन्हें आगे पढ़ने के लिए प्रेरित किया।

----------------------------------------------
मेंडल ने उगाए थे तीस हजार से अधिक पौधे

साधारण से दिखने वाले मटर के पौधों पर शोध कर आनुवांशिकी के सिद्धांत देने वाले मेंडल ने अपने शोधकाल में 30,000 से अधिक पौधे उगाए थे। आठ साल तक चलने वाले इस शोध के लिए मेंडल ने सात जोड़ी स्पष्ट भिन्न लक्षणों वाली किस्मों को चुना।
-----------------------------------------
क्या है मेंडलवाद

अपने शोध के पूरे होने पर मेंडल ने आनुवांशिकता के कुछ सिद्धांत दिए। उनके सिद्धांत को मेंडलवाद कहा जाता है। उन्होंने कहा कि आनुवांशिकता में एक पीढ़ी से दूसरी पीढ़ी में चारित्रिक लक्षणों के हस्तांतरण में ये चारित्रिक लक्षण सम्मिश्रित नहीं होते और फीके नहीं पड़ते जैसा की उस समय के वैज्ञानिक मानते थे। उन्होंने बताया कि इसके केंद्र में अवश्य ही कोई ठोस अविभाज्य इकाई या कण है। हां आनुवांशिकता की ये इकाइयां भले ही पहली संकर पीढ़ी में एक समान रहें, लेकिन अगली पीढ़ी में फिर से एक निश्चित अनुपात में प्रकट होती हैं।

U.S. Economy Vulnerable, Again A Recession Time May Come

U.S. Economy Vulnerable, Again A Recession Time May Come

News Published on : 30th July 2011 in Bloomberg New

The world’s largest economy has yet to regain the ground it lost during the recession and may be vulnerable to a relapse.



Gross domestic product expanded at a 1.3 percent annual rate in the second quarter, after a 0.4 percent pace in the prior period, the worst six months since the recovery began in June 2009, Commerce Department figures showed yesterday. Economists said the slowdown leaves the recovery susceptible to being knocked off course by shocks at home or abroad.

“We are in a fairly risky situation,” said Nariman Behravesh, chief economist at IHS Inc. in Lexington, Massachusetts, the only firm polled by Bloomberg News to correctly forecast last quarter’s figure. “Growth is weak and there are some possible problems out there: our own fiscal situation, Europe’s debt crisis, and there is always a risk that oil prices could shoot up.”



The slow recovery left GDP at $13.27 trillion in the second quarter, below the $13.33 trillion peak of the fourth quarter of 2007, after a recession that was about 25 percent deeper than previously reported. That puts pressure on Federal Reserve policy makers to explore additional steps to boost the economy, including another round of bond purchases.
-----------------------------------------
Recession Risk



“We could see a growing risk of recession in the fourth quarter, early 2012, if in fact the federal government gets it together and makes aggressive budget cuts,” LeBas said.

Economists are lowering forecasts for second-half growth in the wake of the latest GDP numbers and the stalemate in Washington. Behravesh of IHS said growth would at best reach 2 percent this quarter and could come in as low as 1 percent. In early July, he was projecting 3.4 percent.


Joseph LaVorgna, chief U.S. economist at Deutsche Bank Securities in New York, reduced his estimate by 1 percentage point to 2.5 percent for the third quarter, and trimmed it to 3 percent from 4.3 percent for the final three months of 2011.
------------------------------------------

Stocks Decline



Treasuries rallied, sending yields on 10-year notes to the lowest level this year, and stocks fell as economic growth trailed forecasts amid speculation lawmakers will reach a compromise to avoid a government default.

The yield on the benchmark 10-year note decreased to 2.79 percent at 4:21 p.m. yesterday in New York from 2.95 percent on July 28. The Standard & Poor’s 500 Index fell 0.7 percent to 1,292.28.

Revisions to GDP figures going back to 2003 showed the 2007-2009 recession took a bigger bite out of the economy than previously estimated and the recovery lost momentum throughout 2010. GDP shrank 5.1 percent from the fourth quarter of 2007 to the second quarter of 2009, compared with the previously reported 4.1 percent drop.
--------------------------------------------------------
Consumers Pull Back


Much of the weakness last quarter came from a pullback in consumer spending, which accounts for about 70 percent of the economy. Household purchases rose 0.1 percent, the smallest gain since the April-June quarter of 2009. The slump reflected a 4.4 percent plunge in purchases of durable goods like automobiles.

Higher expenses for food and energy may have curtailed spending on less essential items. The cost of a gallon of regular gasoline climbed in May to about $4 a gallon, the highest in almost three years, according to AAA, the nation’s biggest auto group.

The absence of faster job growth is also weighing on Americans. The unemployment rate climbed to 9.2 percent in June while payrolls grew by 18,000, the fewest in nine months, Labor Department figures showed on July 8.
-------------------------------------
Employment Outlook

The employment outlook remains dim. Whitehouse Station, New Jersey-based Merck & Co., the second-largest U.S. drugmaker, said yesterday that it plans to cut an additional 12,000 to 13,000 jobs by 2015. Earlier this month, announcements showed Cisco Systems Inc. (CSCO) will trim about 6,500 jobs worldwide; Goldman Sachs Group Inc. may reduce staff by about 1,000, and Lockheed Martin Corp. (LMT) will offer a voluntary separation plan to 6,500 employees.

वे आठ जिनसे मृत्यु भी डरती है

हिंदू पौराणिक कथाओं के अनुसार - वे आठ जिनसे मृत्यु भी डरती है

कहावत है कि मृत्यु के सामने किसी का भी बस नहीं चलता है। किन्तु हर नियम और सिंद्धात के साथ ही कोई न कोई अपवाद भी जुड़ा होता है। अपवाद की इस सर्व व्यापकता से मोत भी नहीं बच पाई है। आज यदि किसी से यह कहा जाए कि इस पृथ्वी पर कोई एसा भी है जो कि हजारों वर्षों से जिंदा है। वो कोई एक नहीं बल्कि पूरे आठ हैं। उन अद्भुत महाप्राणधारी अमर आत्माओं को अष्ट चिरंजीवी के नाम से जाना एवं पहचाना जाता है। यह सुनकर सहसा ही किसी को विश्वास नहीं होगा। किन्तु जो कहा जा रहा है वह पूर्णत: प्रामाणिक तथा शास्त्रसम्मत होने के साथ ही पूरी तरह विज्ञान सम्मत भी है। लीजिये रहस्य से पर्दा उठाते हुए उनके नाम कालक्रम के अनुसार ही क्रमश: प्रस्तुत हैं-

१. मार्कण्डेय : ये अति प्राचीन मुनि हैं जिनका कल्पों में भी अंत संभव नहीं है।
२. वेद-व्यास : ये ब्रह्मऋषि हैं इन्होंने ही चारों वेदों का सम्पादन एवं पुराणों का लेखन कार्य किया।
३. परशुराम : ईश्वर के चौबीस अवतारों में से एक, जो पृथ्वी को अठारह बार क्षत्रिय विहीन करने के लिये प्रसिद्ध हैं।
४. राजा बलि : अपना सर्वस्व भगवान वामन को दान कर महादानी के रूप में विख्यात हुए। इनकी भक्ति से प्रसन्न होकर स्वयं भगवान विष्णु इनके द्वारपाल बने।
५. हनुमान : भगवान शिव के ११ वें रूदा्रवतार, भगवान श्री राम के परम भक्त के रूप में प्रसिद्ध।
६.विभीषण : लंका के राजा रावण के अनुज जिन्होंने राम-रावण युद्ध में धर्म का पक्ष लेते हुए श्री राम का साथ दिया।
७. कृपाचार्य : महाभारत कालीन एक आचार्य जो कौरवों और पाण्डवों के गुरु थे।
८. अश्वत्थामा : ये कौरवों और पाण्डवों के प्रसिद्ध आचार्य द्रोणाचार्य के सुपुत्र थे। इनके मस्तक पर मणी जड़ी हुई थी।

तब समझो आ गई मौत जब इनमें न दिखे खुद की छाया

कुछ हिन्दू धर्म शाष्त्री कहते हैं कि :-  तब समझो आ गई मौत जब इनमें न दिखे खुद की छाया

जीवन का अंतिम अटल सत्य है मृत्यु। श्रीकृष्ण ने गीता में मृत्यु के संबंध में महत्वपूर्ण उपदेश दिए हैं। महाभारत युद्ध में अर्जुन ने अपने सगे-संबंधियों को देखकर धनुष-बाण रख दिए। उस श्रीकृष्ण ने अर्जुन को जीवन और मृत्यु से जुड़ा गीता का ज्ञान दिया।

श्रीकृष्ण ने गीता में बताया है कि जिस व्यक्ति ने इस धरती पर जन्म लिया उसे एक दिन मृत्यु अवश्य ही प्राप्त होगी। मानव शरीर नश्वर है और एक दिन यह अवश्य ही नष्ट भी होगा। आत्मा के संबंध में श्रीकृष्ण ने कहा है कि आत्मा अमर है और वह निश्चित समय के लिए मनुष्य का शरीर धारण करती है। इस समय अवधि के पूरा होने के बाद स्वत: ही आत्मा शरीर छोड़ देती है।



शास्त्रों के अनुसार जब मनुष्य की मृत्यु होने वाली होती है इसके कुछ दिन पूर्व से ही कई ऐसी बातें होने लगती हैं जिनसे अंदाजा लगाया जा सकता है कि व्यक्ति की मृत्यु कब होगी? वैसे तो मृत्यु के संबंध में किसी भी प्रकार की पूर्व भविष्यवाणी करना असंभव सा ही है। ज्योतिष शास्त्र से किसी भी व्यक्ति की मृत्यु का संभावित दिन मालुम किया जा सकता है। इसके अलावा कुछ असामान्य घटनाएं जब घटने लगती हैं तो मृत्यु का संकट शुरू हो जाता है। शास्त्रों के अनुसार जब किसी व्यक्ति को पानी, घी, तेल में स्वयं की परछाई दिखाई देना बंद हो जाए तो उस व्यक्ति की आयु करीब 7 दिनों की शेष है। मृत्यु का समय निकट आते ही व्यक्ति की आंखें कमजोर हो जाती हैं और उन्हें ठीक से दिखाई देना बंद हो जाता है लेकिन अकाल मृत्यु के संबंध में यह बात लागू नहीं होती है।

Fermilab Discovers New Particle Xi-sub-b (baryon)

Fermilab Discovers New Particle Xi-sub-b (baryon)
A Predicted Hadron Has Been Found

It is not the Higgs Boson (GOD Particle) , It is Xi-sub-b is a baryon, meaning it's made up of quarks, one of the fundamental building blocks of matter.

Its components are an up quark, a down quark, and a "strange" quark, which is a heavier variant of the down quark. A normal neutron, which doesn't typically disintegrate in an instant, is made up of two down quarks and an up quark.

In addition to the new particle, scientists at Fermilab say they may be on the verge of proving or disproving the existence of the long-sought-after Higgs-boson, which is thought to be the key to how mass itself comes into being. If it exists, Fermilab's Tevatron particle collider is "close to reaching the critical sensitivity" required to see its effects.



Baryons are particles formed of three quarks, in different configurations. The proton is a baryon that consists of two up and one down quark, and the neutron is two down and one up. The Xi-sub-b has an up quark, a strange quark (yes, that’s its real name) and a heavy bottom quark (again, real name), meaning that it weighs around six times as much as a proton or neutron.

A Hadron is a kind of particle, made of quarks. There are two kinds of hadrons, baryons (made out of three quarks) and mesons (made out of a quark and a quirky quark known as an antiquark).

The neutral Xi-sub-b belongs to the family of bottom baryons, which are about six times heavier than the proton and neutron because they all contain a heavy bottom quark. The particles are produced only in high-energy collisions, and are rare and very difficult to observe.

The Tevatron, located outside Chicago, will be shut down in September. The facility has been made obsolete by the Europe's Large Hadron Collider, currently the world's largest and most powerful particle accelerator.

Actor Navin Nischol dies of heart attack at the of 65 Years

Actor Navin Nischol expired of heart attack at the of 65 Years on 19th March 2011

Noted Bollywood actor Navin Nischol passed away here on Saturday after a massive heart attack.


The 65-year-old actor was travelling to Pune along with actor-filmmaker Randhir Kapoor in a car that morning, when he suffered a cardiac arrest. Mr. Nischol was immediately taken to a nearby hospital, but was declared dead upon arrival.


The funeral took place this evening in the presence of family members and friends from the film industry. The actor’s daughter Natasha, mother Kamla and brother Praveen were present.


He had made his debut with "Saawan Bhadon" in 1970. His last release was "Break ke Baad".


When Nischol made his debut as a hero in "Saawan Bhadon" in 1970, he was labelled the poor man's Rajesh Khanna. Khanna was at the peak of his career then, and had given a superhit — "Kati Patang" the same year. Nischol instantly clicked with the audience, and went on to a silver jubilee at the box office with his debut film. The film also saw the debut of Rekha, Roopesh Kumar, Jayshree T and Ranjeet.

A product of the FTII, Nischol made a successful debut with 'Sawan Bhadon' in 1970 and went on to star in several films like 'Victoria No 203', 'Dhund', 'Chhalia', 'Parwana', 'Buddha Mil Gaya', and later as character actor in 'Major


Saab', 'The Burning Train' aming others.

In the early 90s, he had made a successful transition to the small screen with the popular sitcom 'Dekh Bhai Dekh' alongside Farida Jalal, Shekhar Suman. The show was produced by Jaya Bachchan.

He was last seen in films like 'Khosla ka Ghosla' (2006) and Break ke Baad (2010). His wife had committed suicide in 2006.

His wife, Geetanjali, committed suicide in 2006.

LHC releases first Higgs search results

LHC(Large Hedron Collider) releases first Higgs search results

The Higgs boson, the elusive particle thought to give all others mass, is the most hyped of all the discoveries that the Large Hadron Collider (LHC) is expected to make. Now the Compact Muon Solenoid (CMS) experiment at the LHC has cast its first glance on this prize.


Excitement must be tempered. The LHC, at CERN near Geneva, Switzerland, can't yet compete with the Tevatron at Fermilab in Batavia, Illinois, in hunting for the Higgs as predicted by the standard model, particle physics's most successful framework.

But, as revealed in a paper posted to the online Physics Arxiv on Saturday, the LHC is already closing in on the version of the Higgs that appears in an alternative, more exotic framework.



For the first time, the Tevatron - formerly the world's most powerful particle smasher and the last experiment to narrow down the possible masses that the Higgs might have - can hear a second set of footsteps on its main stomping ground.

The Tevatron experiments have acquired more than 10 inverse femtobarns of data over the collider's 27 year lifetime - nearly 28 times the amount of data collected by the LHC experiments so far.

With this data, it has been steadily closing the window of possible standard model Higgs masses, ruling out those between 158 and 175 giga electronvolts (GeV). Combined with the previous limit from the Large Electron Positron collider, the elusive boson is thought to hide between 114 and 158 GeV - if it fits into the standard model.


In the recent paper, CMS has considered the Higgs boson in a more exotic framework in which the six known quarks are extended to eight and the three known electron-like particles to four.
The researchers find that if our universe is harboring this "extra generation" of matter, the Higgs is unlikely to have a mass between 144 and 207 GeV. Coupled with the Tevatron's exclusion of the range of 131 to 204 GeV, this slightly narrows the possible mass range for the Higgs within this exotic framework.


The LHC is still in the stage of gathering data and proving the reliability of its experiments, but if the new accelerator keeps the pace it set in 2010, it could seize the Higgs baton from the Tevatron, even for standard model Higgs searches, this summer

======================================================================

The three Large Hadron Collider (LHC) experiments that study lead ion collisions all presented their latest results today at the annual Quark Matter conference, held this year in Annecy, France. The results are based on analysis of data collected during the last two weeks of the 2010 LHC run, when the LHC switched from protons to lead-ions. All experiments report highly subtle measurements, bringing heavy-ion physics into a new era of high precision studies.


In its infancy, just microseconds after the Big Bang, the universe consisted of a plasma of quarks and gluons (QGP), the fundamental building blocks of matter. By colliding heavy ions, physicists can turn back time and recreate the conditions that existed back then, allowing us to understand the evolution of the early universe.


Results from the ALICE experiment have provided evidence that the matter created in lead ion collisions is the densest ever observed, over 100000 times hotter than the interior of the sun and denser than neutron stars. These conditions allow the properties of the plasma to be studied with unprecedented detail. ALICE has confirmed the RHIC experiments' finding that QGP behaves almost like an ideal fluid with minimal viscosity. ALICE's presentation also discussed the behaviour of energetic particles in the QGP medium

Large Hadron Collider: Final Synchronization Test A Success

Large Hadron Collider: Final Synchronization Test A Success i.e Successfully Executed

CERN has announced the success of the second and final test of the Large Hadron Collider’s beam synchronization systems. The test will allow the LHC operations team to inject the first beam into the LHC

Friday evening (August 22, 2008), a single bunch of a few particles travelled down the transfer line from the Super Proton Synchrotron (SPS) accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered counter-clockwise about 3 kilometres around the LHC.


“Thanks to a fantastic team, both the clock-wise and counter-clockwise tests went without a hitch. We look forward to a resounding success when we make our first attempt to send a beam all the way around the LHC,” said Lyn Evans, LHC Project Leader.

Purpose of LHC Test : To know creation of Universe, Time Travelling Possibility, Longevity, Existence of God Particle Higgs Boson

Some People have fear about these tests : Impact on Earth, Nature & Living Being

Is time travel possible ? Physics of the Impossible

Is time travel possible ? Physics of the Impossible
IMPOSSIBLE = I M POSSIBLE

Newton said : Time is like arrow, once fired never returns back. One Second on earth is equal to one second on Jupitor.

 Einstein said : Time was  like just like a river, which moved around stars and galaxies, speeding up around light bodies and slowing down as it passed around massive bodies. One second on the earth was Not one second on Jupitor. Clocks scattered throughout the universe and runs with a different speed.

Einstein’s neighbor at Princeton, Kurt Goedel, perhaps the greatest mathematical logician of the past 500 years, found a new solution to Einstein’s own equations which allowed for time travel! The “river of time” now had whirlpools in which time could wrap itself into a circle. Goedel’s solution was quite ingenious: it postulated a universe filled with a rotating fluid. Anyone walking along the direction of rotation would find themselves back at the starting point, but backwards in time!


In his memoirs, Einstein wrote that he was disturbed that his equations contained solutions that allowed for time travel. But he finally concluded: the universe does not rotate, it ex- pands (i.e. as in the Big Bang theory) and hence Goedel’s solution could be thrown out for “physical reasons.” (Apparently, if the Big Bang was rotating, then time travel would be possible throughout the universe!)



Then in 1963, Roy Kerr, a New Zealand mathematician, found a solution of Einstein’s equations for a rotating black hole, which had bizarre properties. The black hole would not collapse to a point (as previously thought) but into a spinning ring (of neutrons). The ring would be circulating so rapidly that centrifugal force would keep the ring from collapsing under gravity. The ring, in turn, acts like the Looking Glass of Alice. Anyone walking through the ring would not die, but could pass through the ring into an alternate universe. Since then, hundreds of other “wormhole” solutions have been found to Einstein’s equations. These wormholes connect not only two regions of space (hence the name) but also two regions of time as well. In principle, they can be used as time machines.


Now new solution of quantum theory to gravity (and hence create a “theory of everything”) have given us some insight into the paradox problem. In the quantum theory, we can have multiple states of any object. For example, an electron can exist simultaneously in different orbits (a fact which is responsible for giving us the laws of chemistry). Similarly, Schrodinger’s famous  can exist simultaneously in two possible states: dead and alive. So by going back in time and altering the past, we merely create a parallel universe. So we are changing someone ELSE’s past by saving, say, Abraham Lincoln from being assassinated at the Ford Theater, but our Lincoln is still dead. In this way, the river of time forks into two separate rivers. But does this mean that we will be able to jump into H.G. Wells’ machine, spin a dial, and soar several hundred thousand years into England’s future? No. There are a number of difficult hurdles to overcome.


Stephen Hawking once opposed the idea of time travel. He even claimed he had “empirical” evidence against it. If time travel existed, he said, then we would have been visited by tourists from the future. Since we see no tourists from the future, ergo: time travel is not possible. Because of the enormous amount of work done by theoretical physicists within the last 5 years or so, Hawking has since changed his mind, and now believes that time travel is possible (although not necessarily practical). (Furthermore, perhaps we are simply not very interesting to these tourists from the future. Anyone who can harness the power of a star would consider us to be very primitive. Imagine your friends coming across an ant hill. Would they bend down to the ants and give them trinkets, books, medicine, and power? Or would some of your friends have the strange urge to step on a few of them?)

Hadron Collider is Producing Nano-Blackholes


Like many physicists, Michio Kaku thinks our universe will end in a "big freeze." However, unlike many physicists, he thinks we might be able to avoid this fate by slipping into a parallel universe. "i


One of the most fascinating discoveries of our new century may be imminent if the Large Hadron Collider outside Geneva produces nano-blackholes when it goes live again. According to the best current physics, such nano blackholes could not be produced with the energy levels the LHC can generate, but could only come into being if a parallel universe were providing extra gravitational input. Versions of multiverse theory suggest that there is at least one other universe very close to our own, perhaps only a millimeter away. This makes it possible that some of the effects, especially gravity, "leak through," which could be responsible for the production of dark energy and dark matter that make up 96% of the universe.

"The multiverse is no longer a model, it is a consequence of our models," says Aurelien Barrau, particle physicist at CERN

While it hasn’t been proven yet, many highly respected and credible scientists are now saying there’s reason to believe that parallel dimensions could very well be more than figments of our imaginations.

"The idea of multiple universes is more than a fantastic invention—it appears naturally within several scientific theories, and deserves to be taken seriously," stated Aurelien Barrau, a French particle physicist at the European Organization for Nuclear Research (CERN).

There are a variety of competing theories based on the idea of parallel universes, but the most basic idea is that if the universe is infinite, then everything that could possibly occur has happened, is happening, or will happen.

According to quantum mechanics, nothing at the subatomic scale can really be said to exist until it is observed. Until then, particles occupy uncertain "superposition" states, in which they can have simultaneous "up" and "down" spins, or appear to be in different places at the same time. The mere act of observing somehow appears to "nail down" a particular state of reality. Scientists don’t yet have a perfect explanation for how it occurs, but that hasn’t changed the fact that the phenomenon does occur.

Unobserved particles are described by "wave functions" representing a set of multiple "probable" states. When an observer makes a measurement, the particle then settles down into one of these multiple options, which is somewhat how the multiple universe theory can be explained.

The existence of such a parallel universe "does not even assume speculative modern physics, merely that space is infinite and rather uniformly filled with matter as indicated by recent astronomical observations," Max Tegmark, a cosmologist at MIT in Boston, Massachusetts concluded in a study of parallel universes published by Cambridge University.

Mathematician Hugh Everett published landmark paper in 1957 while still a graduate student at Princeton University. In this paper he showed how quantum theory predicts that a single classical reality will gradually split into separate, but simultaneously existing realms.

"This is simply a way of trusting strictly the fundamental equations of quantum mechanics," says Barrau. "The worlds are not spatially separated, but exist as kinds of 'parallel' universes."

Partly because the idea is so uncomfortably strange, it’s dismissed as sci-fi by many critics. But there are also many credible, respected proponents of the theory—a group that is continuously gaining new adherents as new research unveils new evidence. Some Oxford research—for the first time—recently found a mathematical answer that sweeps away one of the key objections to the controversial idea. Their research shows that Everett was indeed on the right track when he came up with his multiverse theory. The Oxford team, led by Dr David Deutsch, showed mathematically that the bush-like branching structure created by the universe splitting into parallel versions of itself can explain the probabilistic nature of quantum outcomes.

But if parallel worlds do exist, there is a way around these troublesome paradoxes. Deutsch argues that time travel shifts happen between different branches of reality. The mathematical breakthrough bolsters his claim that quantum theory does not forbid time travel. "It does sidestep it. You go into another universe," he said. But he admits that there will be a lot of work to do before we can manipulate space-time in a way that makes “hops” possible. While it may sound fanciful, Deutsch says that scientific research is continually making the theory more believable.

"Many sci-fi authors suggested time travel paradoxes would be solved by parallel universes but in my work, that conclusion is deduced from quantum theory itself."

The borderline between physics and metaphysics is not defined by whether an entity can be observed, but whether it is testable, insists Tegmark.

He points to phenomena such as black holes, curved space, the slowing of time at high speeds, even a round Earth, which were all once rejected as scientific heresy before being proven through experimentation, even though some remain beyond the grasp of observation. It is likely, Tegmark concludes that multiverse models grounded in modern physics will eventually be empirically testable, predictive and disprovable

What I think about time travel and creation of Universe :


Time Travel is definitely possible today OR tomarrow, It is not a fiction.
As We move forward in time then certainly We can travel back in time also.
But problem arises with paradoxes : Do We change past ?
If concept of parallel Universe is correct as per quantum mechanics theory (A particle can have multiple states simultaneously), then We change history/past also.
We see each & every particles have its anti particle also : i.e Positive  & Negative
for e.g.  Electron -> Positron
For each matter, its Anti matter also present. So that it can be destroyed to release energy.
And on the same concept there may be Negative/Anti Universe can also possible.


In Hinduism, 1 Second of Brahma's is equivalent to more than 1000 years of human.
i.e Time moves with different different speeds in Universe.
We are still ignorant of Science/Creation of Universe. Nature is brilliant in its creation : Green Trees have green insects ( Are these insects use science to change there colours to protect themselves from other creatures).
How Creatures/Animals developed to there survival and how there destroyer developed skills to kill such creatures/animals. ( Do they use science OR there is some thinking power for there development, We don't know, And We are thinking of Lemark's OR Darwin's principle, And it is unlear how each/every creature developed in such a way to change even colour, eyes, flying, othere special possibilities).

We are asking - If God created this universe, then from Where God comes.
But there is one more question : How this matter & energy is created. How Big bang comes, And what happend before Big Bang.Do We ceated from ZERO (And Positive & Negative energy creates, But How & Why it creates)

There is one more possibility, May be there is some advanced civilization who now so advance that they works like GOD.
And may be We can achieve such stage in future.

---------------------------------------------------------------------------------------------------


As We are editing video films/ photo (Which is a past event) , One day human being may go to past/future
(For e.g. Light of thousand years far star reaches us after thousands of years, And that time We see past of that star, While observer on that star is in future of that star.)
, And can rereate same things once again.
( I have firm beleive on this, And I hope it can't be disprove).
Each and every particle absorbes/release energy at each & every moment when the event happens. And When We are able to decode this particle energy then We can create picture of past event happened.
And on the basis of that We can recreate the same.

IMPOSSIBLE = I M POSSIBLE

Each & every thing is possible with a positive direction/ positive energy.

Negative people can't find a solution.

I am saluting Mr. Ronald Mellat for his brave effort to try to bring his father back, And giving us many valuable information.
I am saluting to the scientists, Who gives us so many things and a great platform to futhur developments.
I felt now new developments can be fastly possible through Internet, which can works like a water at the time of origin of universe through which many species combined to create complicated species.

I hate terrorists, Who don't know what is the value of a life, Don't know the purpose/meaning of there objectives.

World's all religion should think & work in a Unified approach.

Heart attacks & First Aid

Heart attacks & First Aid

A heart attack is one of the most common life-threatening heart conditions in the India

If you suspected someone was having a heart attack, what would you do? : -

Heart attack symptoms - lips turning blue , profuse sweating , extreme gasping for air , sudden fainting or dizziness , persistent, vice-like central chest pain.

Treatment for heart attacks

1. Sit the person down.
2. Call an ambulance immediately, even if you are not sure about the symptoms.
3. If the person is conscious, give them a 300 mg tablet of aspirin to chew.
The main risk is that the heart will stop beating. Be prepared to resuscitate if necessary.
Source : http://www.redcross.org.uk/What-we-do/First-aid/First-aid-tips-and-videos/Heart-attacks

========================================================================
Symptoms

•Severe chest pain that doesn't ease with rest
•Breathlessness and nausea
•Giddiness
•Sense of doom
•Irregular pulse
•Ashen, cold skin and blue lips
=======================================================================
Heart attack – emergency first aid

What should you do if someone has a heart attack?

A heart attack will cause severe chest pains behind the breast bone, often radiating towards the left arm.
If someone has a cardiac arrest or heart attack, there may be only a few minutes to act before it is too late. It is vital to know what to do beforehand.
To perform CPR (cardiopulmonary resuscitation) and artificial respiration (mouth to mouth resuscitation) effectively, training and frequent practice on resuscitation dummies are essential.
------

How can you tell if someone is having a heart attack?

If the person is unconscious:
are they breathing? Look at the patient's chest to see if it is rising and falling
do they have a pulse? Place two fingers on one or other side of the person's voice box in their throat to feel if they have a carotid pulse.

If the patient has a pulse but is not breathing:
Could it be because of suffocation? Feel inside the mouth with a finger to see if there is anything blocking it or the windpipe and remove any food or other objects. Provided that dentures are not broken, it is better not to remove them

call for help immediately, stating that the casualty is not breathing, and provide resuscitation (see below) until the patient begins to breathe or the ambulance arrives.

If there is no breathing or pulse, the patient has had a cardiac arrest.
-----------------
What help is needed?


Immediately place the palm of your hand flat on the patient's chest just over the lower part of the sternum (breast bone) and press your hand in a pumping motion once or twice by using the other hand. This may make the heart beat again.

If these actions do not restore a pulse or if the subject doesn't begin to breathe again:
call for help, stating that the casualty is having a cardiac arrest but stay with the patient find out if any one else present knows CPR provide artificial respiration immediately (see below) begin CPR immediately (see below).
How to give artificial respiration
Tilt the head back and lift up the chin.
Pinch the nostrils shut with two fingers to prevent leakage of air.
Take a deep breath and seal your own mouth over the person's mouth.
Breathe slowly into the person's mouth – it should take about two seconds to adequately inflate the chest.
Do this twice.
Check to see if the chest rises as you breathe into the patient.
If it does, enough air is being blown in.
If there is resistance, try to hold the head back further and lift the chin again.
Repeat this procedure until help arrives or the person starts breathing again.
How do I perform CPR (cardiopulmonary resuscitation)?
See if there is breathing. If not, start artificial respiration as described above. Checking for a pulse in the neck (carotid artery) may waste valuable time if the rescuer is inexperienced in this check. The procedure is:
place your fingers in the groove between the windpipe and the muscles of the side of the neck. Press backwards here to check for a pulse.
If there is no pulse, or if you are unsure, then proceed without delay thus:
look at the person's chest and find the 'upside-down V' shaped notch that is made by the lower edge of the ribcage. Place your middle finger in this notch and then place your index finger beside it, resting on the breastbone. Take the heel of your other hand and slide it down the breastbone until it is touching this index finger. The heel of your hand should now be positioned on the middle of the lower half of the breastbone.
now place the heel of your other hand on top of the first. Keep your fingers off the chest, by locking them together. Your pressure should be applied through the heels of the hands only.
keep your elbows straight, and bring your body weight over your hands to make it easier to press down.
press down firmly and quickly to achieve a downwards movement of 4 to 5cm, then relax and repeat the compression.
do this 15 times, then give artificial respiration twice, and continue this 15:2 procedure until help arrives.
aim for a rate of compression of about 100 per minute. You can help your timing and counting by saying out loud 'one and two and three and four ...' etc.
Artificial respiration and CPR should both be performed at the same time
If possible, get someone else to help – one person to perform artificial respiration and the other to perform CPR. (This is not easily done without prior practice and it is well worth attending sessions on CPR training to become familiar with the technique.)
The ratio of chest compressions to breaths is 15:2 for both one-person and two-person CPR.
Continue until the ambulance arrives or the patient gets a pulse and starts to breathe again.
If the pulse returns and breathing begins but the person remains unconscious, roll them gently onto their side into the recovery position. This way mucus or vomit can get out of the mouth and will not obstruct the patient's breathing. It also prevents the tongue from falling back and blocking the air passage.
Make sure the patient continues breathing and has a pulse until the ambulance arrives
If you succeed in resuscitating the person who has been taken ill, he or she may be confused and alarmed by all the commotion. Keep the patient warm and calm by quietly, but clearly, telling them what has happened.
Again, it needs to be emphasised that the only way to provide proper first aid and resuscitation is through learning the technique, then regular practice and guidance.

==================================================================
Aspirin works to help prevent blood clots.

During a suspected heart attack, aspirin can play a critical lifesaving role if taken as directed by a doctor.

Research has shown that aspirin reduces the risk of death by 23 percent if administered when a heart attack is suspected and for 30 days thereafter. Aspirin can also lessen the damaging effects of the heart attack. The use of aspirin as a “heart attack first aid” could potentially save 10,000 lives each year.

The mechanism by which aspirin works in the treatment of heart attack is not completely understood. However, we do know that aspirin help reduce platelet clumping or blood clotting which helps cause blockage in blood vessels.

Travelling in Past - Immortality - God

Travelling in Past Future - Immortality - God
IMPOSSIBLE = I M POSSIBLE



We people are searhing from a long time about God and its existene. And recent discoveries suggests Humans may work like God.

Two prominenet scientists Michio Kaku and Dr. Mallat are working to make a Time Travel machine as per Albert Einstein's General relativity theory, So that they can travel in past and in future and to change it.

Many people are asking about Grandfather Paradox and how it can resolved.
Grandfather paradox is - A person travel in past and murder is Grandfather then how that person comes in existence.
But new theories gives a hope to solve this - Which is existence of parallel universe that is if a person go backto in past and kill is grandfather then a different event is generated and is done in a different parallel universe. There are infinite number of parallel universe for every cause & effect event, which is invisible and made up dark matter.

Every since it was given serious credibility in 1949 by the great logician Kurt Godel, many eminent physicists have argued against time travel because it undermines ideas of cause and effect. An example would be the famous “grandfather paradox” where a time traveler goes back to kill his grandfather so that he is never born in the first place.

There is one more scientist/professor - Dr. Ronald L Mallet, Who is making a time travel machine to brough back is father who was died by a heart attack at the age of 33 when Dr. Mallet was 10 years old.

Dr. Mallet is claiming that he is near to make this Time Travel machine.
He was working from last 56 years from the age of 10 when his father was died.

Dr. Mallet Time machine project

For quite some time, Ronald Mallett has been working on plans for a time machine. This technology would be based upon a ring laser's properties within the context of Einstein's Theory of Relativity. Mallett first argued that the ring laser would produce a limited amount of frame-dragging which might be measured experimentally, saying:

"In Einstein's General Theory of Relativity, both matter and energy can create a gravitational field. This means that the energy of a light beam can produce a gravitational field. My current research considers both the weak and strong gravitational fields produced by a single continuously circulating unidirectional beam of light. In the weak gravitational field of an unidirectional ring laser, it is predicted that a spinning neutral particle, when placed in the ring, is dragged around by the resulting gravitational field."

In a later paper, he argued that at sufficient energies, the circulating laser might produce not just frame-dragging but also closed timelike curves (CTC), allowing time travel into the past:

For the strong gravitational field of a circulating cylinder of light, I have found new exact solutions of the Einstein field equations for the exterior and interior gravitational fields of the light cylinder. The exterior gravitational field is shown to contain closed timelike lines.

The presence of closed timelike lines indicates the possibility of time travel into the past. This creates the foundation for a time machine based on a circulating cylinder of light.

Funding for his program, now known as The Space-time Twisting by Light (STL) project, is progressing. Full details on the project, Mallett's theories, a list of upcoming public lectures and links to popular articles on his work can be found at the Professor's UConn web page, and an illustration showing the concept on which Mallett has designed the time machine can be seen here.

He also wrote a book entitled, Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality, co-written with New York Times best-selling author Bruce B. Henderson, that was first published in 2006. In June 2008, motion picture director Spike Lee's production company announced it had acquired the film rights to Mallett's book. Lee is co-writing the movie script and directing the picture.

In 2006 Mallett declared that time travel into the past would be possible within the 21st century and possibly within less than a decade. Mallett uses Albert Einstein's General Theory of Relativity to attempt to substantiate his claims.
