‘Look’ at an electron and it changes its state!
When we want to look at something we usually’ throw a little light on it’. ie we hit it with photons.
When you hit a TV or a book with photons, it absorbs a few and reflects a few and that gives you a clue about the TV or the book. Then you can go and pick up the book for example.
Electrons are tiny little critters. You hit an electron with a photon and it will fly off or move off. Its state will change. Its like hitting a candle with a ball.. something like that. Comparable energies and sizes and so on.
So its not magic. Just size.
Ever run a project where you had to generate so many reports that the very act of monitoring made you risk your deadline?
If you want to observe an electron and “leave it standing” you have to think of something else other than bombarding it photons.
How big is an electron?
According to one estimate, the size of an electron is : 2.82 x 10-13 cm and It’s mass is about 9.10938215(45)×10−31 kg See : http://www.dimensionsguide.com/what-is-the-size-of-an-electron/
But how big is a photon?
“…….of the physical dimensions of a photon. On that topic, I must say that since the photon consists of changing energy fields, the photon encompasses that volume of space in which those energy fields have significant effect.
Thus, if a photon from a radio wave passes close enough to a receiving antenna, it will transfer its energy to the antenna, giving rise to an electrical signal even as the photon itself ceases to exist. The “size” of the photon is that volume of space within which this phenomenon can occur.
The higher the frequency of the photon, the higher its energy level. Therefore, such photons will have a correspondingly larger field of influence than their lower-energy counterparts…..” (Source : http://www.play-hookey.com/optics/photon_characteristics.html)
“In the wave idea of light, colour is determined by the rate at which the wave wiggles; a rapid, energetic wiggle for blue and a more leisurely wiggle for red. You can measure the distance that the light travels for each wiggle, and this is the ‘wavelength’ – it appears to be less than a thousandth of a millimetre for light….
The apparent length (in the direction of movement) of a moving object gets smaller as its speed approaches the speed of light… Since a photon travels always at the speed of light then it will always appear to have no length at all. This is, of course, whilst it is on the move…
We cannot know its size or shape. The appearance of light itself turns out to be a real secret; we cannot see that which we use to see everything else” (Source : http://www.oxygraphics.co.uk/photons.htm)
