Scientists and their Contribution

Today is the birthday of Abram Fedorovich Ioffe who was born in Romny, a small town in the Russian Empire (and now in Ukraine) in 1880. He studied at the Saint Petersburg State Institute of Technology and then earned his Ph.D. under Wilhelm Roentgen at Munich University in 1905. Independently of Robert Millikan, he determined the the charge of the electron by balancing charged microparticles in an electric field against gravity. The Ioffe Physico-Technical Institute and a crater on the Moon were named in his honor.

Happy B day to Abram!
 
Today is the birthday of Homi Jehangir Bhabha, who was born in 1909 in Bombay, India. After studying mathematics and nuclear physics at Cambridge University, he was visiting India on holiday in 1939 when World War II began and decided to stay in his home country and took a job at the Indian Institute of Science. In 1945, he worked with J.R.D. Tata to establish the Tata Institute of Fundamental Research in Bombay.

Happy b'day to Homi Jehangir Bhabha!

He was a great visionary. Indian science will always remain grateful to him.

Today is the birthday of Chandrasekhara Venkata Raman, who was born in 1888 in Tiruchirappalli, India. In 1928 he found that when light passes through a substance, some of the scattered light changes wavelength. Raman's discovery not only provided evidence of the quantum nature of light and matter; it also led to new spectroscopic technologies. He was awarded the 1930 physics Nobel "for his work on the scattering of light and for the discovery of the effect named after him"

Happy B'Day!

He was the first Physics Nobel laureate from Asia. Interestingly his nephew Prof Subramanyan Chandrasekhar too got the Nobel Prize. Majority of Indian Nobel Prizes have Bengal connection. Raman too was working in Calcutta in Governments' Finance department. He used to do his physics experiments in the laboratory of Indian association for the cultivation of science during his spare time. It is here that Raman did most of his path breaking research work.

Today is the birthday of Abraham Flexner, who was born in 1866 in Louisville, Kentucky. After studying medicine, Flexner devoted the rest of his life to reforming education in schools and universities. His friendship with philanthropists Louis Bamberger and Caroline Bamberger Fuld led to the foundation in 1930 of the Institute for Advanced Study, an independent postgraduate center for theoretical research and intellectual inquiry located in Princeton. Flexner served as IAS's first director and recruited, among others, Albert Einstein, John von Neumann and Kurt Gödel. IAS remains a center of excellence.
 
Today is the birthday of William Herschel, who was born in 1738 in Hanover, Germany. Herschel's first career was as a musician and composer. Having left Germany at the age of 19 for England, he began a second career as a telescope builder and astronomer. He discovered Uranus, two of its moons and two moons of Saturn. He also mapped the Milky Way and discovered infrared radiation

Amazing work!

Really amazing man with such diverse interests. I know of many scientists who were good in playing a particular instrument, but not many who started their career from music and ended up scientists. Einstein used to play violin. Our own CV Raman did lot of work on drum sounds. Even late Prof Raja Ramanna was a good piano and violin player.

A day or 2 ago, it was the birthday of Mikhail Lomonosov, who was born in 1711 on an island near Arkhangelsk, Russia. Lomonosov was a prominent scientist during the Russian Enlightenment. He made contributions to physics and other sciences. He was the first to freeze elemental mercury and the first to hypothesize, based on observations, that Venus has an atmosphere

Cool!

डॉ. फ़्रेडरिक सेंगर का कल निधन हो गया।

डॉ. सेंगर ने इंसुलिन नामक प्रोटीन को सीक्वेंस (सूचीबद्ध) किया था और इसी के कारण डायबिटीज़ के मरीज़ों को इंसुलिन उपलब्ध हो पाया। इस खोज के लिए 1958 में डॉ. सेंगर को रसायन शास्त्र का नोबेल पुरस्कार दिया गया।

1980 में उन्हें एक बार फिर से रसायन शास्त्र का नोबेल पुरस्कार दिया गया! इस बार उन्हें यह सम्मान न्यूक्लिक एसिड को सीक्वेंस करने के लिए दिया गया था। इससे विभिन्न जीवों के डी.एन.ए. को समझने में मदद मिली और बहुत-सी बीमारियों के बेहतर इलाज की खोज आसान हुई।

डॉ. सेंगर जैसे वैज्ञानिक मानवता के रत्न हैं। इंसुलिन की उपलब्धता ने करोड़ों जाने बचाई हैं और करोड़ों लोगों को बेहतर जीवन का वरदान दिया है।
डॉ. सेंगर को हार्दिक श्रद्धांजली।
 
Dr. Sanger, a British, was 95 when he died. He is known to be quite a self effacing person and loved gardening. Part of his research actives were self financed.
