This year’s Nobel prize in Chemistry. Reply

What happens when some UV falls on biological molecules? (or any kind) some of these molecules like the wooden pole absorb the energy and there still remains energy which they can emit as visible light. So the UV light kicks the molecules and the molecules in turn emit visible light. This implies that the UV wavelength that the molecules absorbed energy at are very small compared to the wavelength at which they emit visible light. This is always the case.

When we say some materials are fluorescent it means they absorbed higher energy and emitted lower energy radiations of colorful light.

But this has a great deal of application apart from its theoretical interest. More…

India’s Navigation Satellites. Reply

Soon India will launch its navigation satellite on October 10. Its the 3rd of the 7 that India will set on voyage above Indian Nation’s geo-spatial surface, all of which will be set to function in their orbit by next year. India has taken its strides into space.

“This will provide terrestrial, aerial and marine navigation accurately and help disaster management, vehicle tracking and fleet management, mobile phone tracking, mapping of terrain as well as air and sea navigation.”

Despite of the fact that theoretically we have better than mm range accuracy … More…

Happy birthday Newton, but really? Reply

There are no merry Christmas or happy Diwali at the level of the quantum. At that level we are all screwed, and the only things that worked out in our favor is a likelihood thats a part per million. Thats why scientists call it: contingent, laws of nature are arbitrarily, favorable to our existence and not drafted by the mercy of a wishful blown-up entity as desired by intelligent design and goes by various names or forms. Thankfully enough, explicitly enough we have accessed the quantum since a 100 years although even the Greek Philosophy talks about indeterminacy of truth. Thankfully enough we have also traversed as far as we could in our mission to know the cosmos, but we have been doing the first works since the time of Galileo. Newton, happy belated birthday Sir, last time we met was a bust of yours, standing in a garden, good enough only to make a joke about and of you, that was 3 years ago, you have changed the course of Physics for all time to come, in the right direction, more or less, by differentials, the ones that you invented, and the ones that we are still putting into our favorite computers, just like you were using the formula of Ibn Sahl … More…

New 4-quarks at BES-III, China. 1

Chinese particle accelerator BES II discovered a slew of particles that are 4-quarks. They are centered about a mass of 4 GeV. (a very small fraction of GeV up and down)

(If your battery is 1 Volt then it will accelerate your electron to 1 eV, you need then 1 billion = 10 crore batteries to achieve this sort of energy, may be much more than 40 crore batteries actually)

Some of these 4-quarks are also confirmed by Belle, Tsukuba, Japan (where I worked) and BaBar, California, USA.

India has planned its 1st-ever particle accelerator for a decade now which is already working its Physics and design out but facilities have been stopped by environmentalists and Governmental apathy. (or is it purely political or even cultural apathy?)

A Physicist is a physicist’s way of talking about himself. Reply

In my case therefore you see, 0 publications in 2001. The year I joined my PhD, I was learning more about snow-fall, JC Peney and Bus rides. 2002 I have hardly 1 or 2, that was the year when in the later half I was given the privilege of being able to sign for science papers. The next year I am already acquainted quite a bit, so signing more than 1 paper a month is no irksome involvement. I already know what I am signing it for. 20 papers a year. Then it grows to 60 papers the next year, thats papers a month, my team of 400 was producing where I have a legit share of expert contributions, through weeks of data-collection, analysis and data-mining etc. (There would be papers where I won’t have legit share, .. ) The next year 2005-2006 was my peak, 70 papers, You can check my pictures from 05-06 (on f-b) and see how much I was involved in the literally tons of ways experimentalists contribute 😉 No kidding not everything is visible outside the vacuum pipe, its risky)

Then you can see I am gradually climbing down, but its hard enough to climb down faster because you already have a history. Becoming celebrity is a one way affair, no return. With years my direct contribution goes down but history has that which is yet to come and that shows up as bigger share in contribution. (Just like the electron’s history-of-all-path must contribute towards its momenta for future)
I think thats a good connection, like the electrons the Physicists are lost, they are picking on different things and survive and their history makes it bigger. More…

Neutrinos, the new smurfy hulks. Reply

Looks like a well done Physics measurement.

These tiny little morons called as neutrinos are now becoming ubiquitous (some would take an objection to me calling these beautiful smurfs morons simply because I don’t get them, what are they saying again? blurp blurp blurp this time time we have a lotta energy, wanna mess up buddy?)

Ubiquitous is not an adjective for only finding 28 of them. But compare that to how many would be found if we are not to have smart technology and a dint of luck and a lot of hard work, probably 0.3 neutrinos, confirmed by a Bayesian technique opposed to say a frequentist method (are they the same, I won’t know since I am a science writer lol) !!
