Why human eyes are sensitive to only visible light?

“Why Human Eyes Are Sensitive To Only Visible Light”. These processes are arbitrary, which is somewhat more technically referred as “contingency”. Its not just for the case of vision that this arbitrariness is present, but all forms of biological properties. eg A conch shell is spiral in a certain way and this is only specific to the snail-likes. Fur is different for different animals. Arms and limbs are different for different animals. This is because of such arbitrariness which are present in 100s of different ways depending on exactly how a life form develops. ( — We are all describing this on general terms, here in this discussion).

Technically, adaptation has to do with exposure. One has to be exposed to the kind of situation one is borne in. Human beings are not borne deep down, on the ocean bed, but on ground with optimum temperature and other life conditions. So, there has to be optimal amount of heat present. Human Beings can’t survive huge temperatures. But many animals can, so they are exposed more harshly to Infra Red (IR) etc. Its the whole body which evolves and then different parts might evolve differently. [w.r.t. different thermodynamic and other life defining conditions]

Just a wild guess: may be some animals were borne [created by contingent chances] very close to volcanic eruption, eg snakes, which is why they could be sensitive to IR type of vision. etc etc. On planet earth, optical light comes only from Sun, (in its profusion, can turn off the sun during night or moon some nights and its total darkness). This sun-light in optical radiation window is extremely intense in visible spectrum but with IR spectrum its intense only during summer. This intensity going from one place on planet earth to another can vary between say 10% – 60% during a year. That means the likelihood of birth can be reduced by that factor towards IR exposure, if it were to come from sun but not from volcanoes. The actual condition on earth might …

The Chandra Angle !!

But the neutron stars are still quite large. This is because the electrons are about 1000 times as longer in how much space they require to sit in that system, than the neutrons. the neutrons are heavy hard attitude guys, they will go no where. But the electrons while occupy such a large couch are far far less heavier than are neutron. So they are basically whats called “soft”. They are long legged and eat less energy and when vanish the neutron stars have collapsed into an adjacent mass state but quite so very smaller in volume, a 1000 times, smaller.

So two things happened that are called supernovae (that is super star phenomena).

1. (Type Ia supernovae) White dwarf > induced by atomic disintegration due to gravity pressure > Core of the star

2. (Core collapse supernovae) Core of the star > induced further by emission of electrons > neutron star

What are Gauge Potential, Whats a “Theory” in Physics?

Potential was, as said above, is, energy per unit mass or charge. So, we see that, in defining the higher quantity energy or potential (higher therefore closer to action, hence more fundamental or unified) we have to INTEGRATE the lower variable, here, Force, Field or (Any ) 3-vector. This entails therefore arbitrariness into the Physical solution when we solve for these quantities. These physical problems, as they involve differentials or integration, leads to a differential equation. Under further suitable physical conditions called eg laws of nature or physics, become whats called a wave-equation or for particles, equation of motion. We can say equation of motion for particles or equation of motion for waves if they are separate.

Now that we understand what are potential, field, vector and gradient and integral in relation to each other, comes requirements called as symmetry or laws of nature or laws of physics or in simple, boundary conditions to these differential equations known as, wave equation or equation of motion of particles OR waves. ( — which are separate so far )

These equations constrained by the conditions or restrictions which are attributes of physical observation, must therefore unite these variables (potential, field) into one entity which would satisfy the wave or particle equations of motion, the differential equations of motion in PARTICULAR ways only, known as Laws of Nature or Physics. So they become, from their 3-vector or scalar attributes, 4-vectors (or still higher, Tensors).

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

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.

Neutrinos, the new smurfy hulks.

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) !!
