So in a close circle with too much high speed ,we would found electron at each point of circle(at everywhere in the circle)in a time interval of like 1 second.So probably if this is correct,because of this we see things static in life.So we can say high speed in a closed circle show particle static.Question is that all this is correct or not?

Your conception of the electron orbiting the neucleus (which was originally proposed by Neil Bohr) is very outdated and unfortunately wrong.

The electron exists somewhere closeby the neucleus of an atom due to the electric charge attraction between the proton and the electron, but the electron (a fermion) must occupy an available and stable quantum state, which also means that electron will have a certain amount of energy. And while the electron is in this quantum state around the neucleus, its existence can only be described as an electron "cloud". This does NOT mean that there is an actual cloud around the neucleus. This means that we do not know where the electron is. We can only say that the probability of finding the electron here or there is this or that. This has to do with the Heisenberg's Uncertainty Principle.

So you ask what speed is the electron moving around the neucleus? That is equivalent to asking what is the momentum of the electron (because momentum is "mv", mass times velocity). It turns out that Heisenber's Uncertainty Principle tells us that if we know very accurately what is the electron's momentum, then we will not know what is the electron's position, and similarly if we know the electron's position very well, then we wouldn't know what is the electron's momentum.

So if we were to probe an electron and determine its momentum while it is in "orbit" around a neucleus, the very act of probing will knock the electron out of the "orbit' and we will no longer know where the electron is. So we will know the momentum of the electron, but we can no longer say that the momentum we measured is the electron's speed around the neucleus, because the electron is no longer there.

And if we were to fix the electron's position to be somewhere in "orbit" around the neucleus, then we will have no idea what is its momentum. So the answer to your question is: we do not know what is the speed of the electron in "orbit" around the neucleus because of Heisenberg's Uncertainty Principle.

I get where you're coming from I think, however I'm not sure we can see individual atoms in any case. If you mean our brains aren't quick enough to discern the jiggling of thermal, and kinetic motion at a molecular and atomic level, you'd be right, I'd say.

The following may help.

http://en.wikipedia.org/wiki/Hydrogen_atom

Although the mean speed of the electron in hydrogen is only 1/137th of the speed of light there is an increase in the electron's momentum which is not quite linear with velocity, as predicted by special relativity. The relativistic mass of the electron may be said to increase.

A group of German neuro-physicists say they've discovered an upper limit on how fast human beings can think. It all depends on how closely connected the brain's nerve cells are.

If you've ever been envious of people who seem able to think faster or be more coordinated, take heart. There is a limit, it seems, even for them.

Three theoretical neuro-physicists from the Max Planck Institute for Flow Research in Göttingen used models of neural networks in the brain to discover an upper limit to the speed of thought.

And on it goes, but doesn't actually give a frame per second rate.
------------------------------------------------------------------------------------
In any case, the rate our brain can discern motion is enormously less than alpha-c, at anywhere near the scale you're talking about.
One can tell by the way a spoked wheel appears to turn backwards after just a few revolutions per second or thereabouts. Faster still and they'll become a blur, seeming semi-solid.
Translate this to the molecular, or atomic scale, and you have your answer I imagine. Irrespective of Heisenberg's uncertainty.

Yeah, it rather is genuinely impressive isn't it. some russian astronauts as quickly as spent an prolonged trip in area, traveling at some 5,000 miles in keeping with hour. They spent plenty time in area they had fairly elderly 2 seconds decrease than human beings on earth. i realize it rather is fairly miniscule and insignifcant, even though it fairly is cool. think of in the event that they were traveling at close to the cost of sunshine; they could have come again to earth and experienced that some years had long previous previous on a similar time as they had basically elderly some weeks. study Michio Kaku's books - Hyperspace, pararell worlds and that i won't be able to remember the 0.33 one. they are rather stable, it fairly is approximately thoretical physics!

Just because it is in circle , consider that if it was in a straight line that will mean it Will be more static than that

No, not correct. As a start, look on wikippedia maybe for Heisenberg.
