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…

A new optimization parameter in a statistical sample ! Reply

It reflects the quality scope of the citations. Its the total percentage of a citation that goes into defining a particular citation index. Let me call it q-index therefore (q for quality)

See this example.

My h-ind is 60. So total (minimum) citation it accounts for is 60*60 = 3600. My total citation is 12215. So my q-ind is 3600/12215 = 29.47% Or 29.47% of my total citation were important for this parameter. Hence my q-index is 29.47. In this way if someone has 500 total citation with h-index 60, he has a much better q-index than mine, because more of his paper are highly cited More…

Uncertainty Principle Again. Reply

2. The object can be a large object, eg say something whose picture you are taking. But as explained above its not the energy of the object (or momentum) which is directly coming into the problem. That would be an added degree of concern if the object is moving with certain velocity, a reason why pictures are blurred. Because motion of objects introduces additional energy-time-momentum-position variables and their corresponding uncertainties. For the argument of the above problem one can imagine the large sized object, lets say a bird, is standing still on a tree while its picture is being taken. In that case if the wavelength of the light [few 100 nano meters = 1/10th of a micrometer] is used (eg in a digital-camera) the corresponding accuracy of the light will be less than micrometers. You can take a very sharp picture of the bird, which is lets say 6 inch long. But when you zoom in to a large degree, the inaccuracies will show up. [in this case how to see a micrometer level image? Is a computer sufficient to show us the uncertain edges of the pixels?] If the wavelength (here visible light) is so small, evidently by de-Broglie relationship, momentum or energy of such light is very large. But its not as large to disturb the feelings of the bird. The bird doesn’t have a problem with visible light, and such energy does not disturb its position or energy or any thing so to say. So while Quantum Mechanics is valid, we are accustomed to say this is a classical mechanics situation. To say QM is invalid is incorrect. To say QM is understood to be valid is a knowledgeable position. More…

Why Japanese is the most elaborate Language? Reply

Couple years ago, for this reason, not the kai reason, but any phonetic-word-attempt which gave me tons of kanjis, for same phonetics, I said, Japanese Language has so many synonyms, (perhaps this is anti-synonym, but in my defense, I don’t remember exact word I used, its a memory retrieval, you see) and still Japanese Language unites them all and makes into one language; we can also do this for Indian language.
Indian (Language) would be far easier (than the complexity of Japanese) in that, given, lets say, jack-fruit will have 8 different words only, across India, then, we have to put them all into one syllable-alphabet unit (that can be newly defined, because now we have at-least 20 ways to define) eg Hindi: kathar/kathal, Odi: panas (Telugu also Panas, I know, I asked this to my friend 15 years ago, he was from AP, his name Venkateswaralu Goruganthi, funny fella with thilak on his head, see since when I am doing my language research?) I don’t know more language, lets say: Gujurati: xyz.

Then take all Indian Language and list these into one unit. That unit would be given a special phonetic tag. (Because we don’t have any) The reverse of this has been accomplished by Japanese. By having each meaning for a single phonetic or syllable unit as a kanji (or pictorial unit) they have unified language. Back then I said, 20 some synonyms, (so many = 20) Lets count today.
As if a coincidence I found 20. Although, there would be, some redundant issues here (eg 買い and 買 ) and a few more may be left. (eg I remember, now I know some Japanese Language by memory: kai = write, kai in kaishi = begin). Lets see what we found in Japanese for kai; each of the following is kai, with different meaning. Only one is (sa)kai and couple are not known (just kai, in 2nd line), from where I am searching. Lets then, give their meaning.

The MOST unique caption in the world.

Caption (#mdashf): I am the only person who has taken the picture of all of humanity keeping myself impossible to be pictured by anyone. 

The Viral-nova caption is kind of not clear;”This photo was taken by astronaut Michael Collins, when he took this photo he was the only human, alive or dead, that wasn’t in the frame of this picture. He traveled with Buzz Aldrin and Neil Armstrong and orbited the moon whilst they were landing to study the surface of the moon from farther out.”

Caption: (#mdashf) Dear Galaxies, we just clicked your 10 billion year old picture.
