## How heavy is water molecule?

Saturday, February 19, 2011 at 4:30 am UTC + 05:30 Just a simple calculation, I did, says; the heaviest meson we know, is 35% lighter, than the water molecule, and about 22000 times heavier than electron. I am thinking along side the PDG list of particles; all atoms and molecules can have their properties mentioned … A quick division by 0.35 gives that water molecule is therefore, 62.86 K heavier than one electron. Thus the water molecule nucleus is 6.29 K times heavier than the total electrons it has revolving around its nucleus. (There are 2 H and 1 O = 10 electrons right? Or is it 18?)

Updated Discourse.

If you ever seem, to be caught up between: they say light always moves at the same speed-c, they keep on harping, why then, its energy so different; we have light of various energy and frequencies. One that are harmful, like x-ray or ultraviolet and one that are quite soft on us all. The answer is there are two kinds of speed, when it comes to vector emissions like light, one speed is on the plane of polarization, giving us the energy or frequency or intensity of light waves, and the other, the speed perpendicular to that plane, that is; the speed at which energy of light is transmitted across the galaxy, its this latter speed, which is slated to be known as speed-of-light (instead of, speed of light’s energy transmission vs speed that determines the energy value of light transmission) and always a constant known as c, whose value is unchanged, as long as a single quantum of light is considered and in vacuum.

Note that vector emission means there are 3 dimensions, in which this wave is created or propagated, light wave, its a plane + a perpendicular dimension to that plane. The plane is called plane of polarization which always contains two fields, Electric and Magnetic field, and the perpendicular dimension is the direction in which the energy of the light wave is propagated, therefore, gives the light-wave-speed; which are again of two definition, the physical or actual speed known as group velocity, and the virtual, conceptual speed of each wave train, known as phase velocity. This definition of phase and group velocity are always to occur; for any kind of waves and not just light wave. So, the light-wave-group-velocity (for a single quantum-of-light, called photon) is always c = 2.99 x 10 (8) meters/second, in vacuum.

## 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.

## Does Quantum Mechanics Apply to our life’s tiniest moorings?

The correspondence Principle. This guy which gets talked a lot has a simpler form at times. Again this principle is a specific or corollary of O = A*B with the understanding that even if one of the variable say A can be insignificant it still depends on the sequence of other variables which decides how significant the total outcome would be. Therefore given that B can be significant enough to over ride A’s insignificance the outcome O can be significant. In other words an event might correspond from a scale of insignificance to a scale of significance. Often a scale of insignificance can be the micro or nano scale and the scale of significance is reached because it is not insignificant. So there is a bridge between two scales, one of insignificance and one of significance. One of micro and one that is not micro but lies close. In all totality this is the reason why Quantum Mechanical effects can be carried to the Classical scale and this is known as correspondence Principle.

## Equivalence from simple notions of Geometry ? Yes.

Now it may also be related that light bends in a denser media compared to a rarer media because an additional rotational force is working. In other words, the definition of straight line has to change in the medium, that is of different density, because path of light is changing. Light is the guy who suffers the least when something tries to buzz it, because its inertial property of mass is zero. The curvature of light or the bending or deflection known as Refraction is thus a measure of the sideways force or energy.

Thus speed of light in different media is a measure of this bending or curvature and is known as Snail’s law ( — Pun intended, its actually; Snell’s Law — ) . Automatically when distance and time have to readjust, to produce an angle or bending, known as refraction ( — possible because distance and time can produce an angle if they are equivalents — ) the speed must also change.

All these are inter related. Light refracts and its speed changes, in relative change in density of media because there are rotational or non-inertial effects.

( — or additional energy is available, or a force is acting to bring a curvature in light’s path, perhaps the electromagnetic effects of the molecules? Its not only distance or time that are equivalents, read one article of mine “All You Need To Know About Relativity” to understand; how energy and time and distance and in short all Physical Variables are equivalents of each other — )
