See Those Bosons?

06/01/2015 11:44 AM

the folks at MIT developed a microscope that realty gets down to small

forget theory, they can actually see electrons and quarks amazing research

No, I think the article is referring to atoms with unpaired electrons (Fermions) and atoms with no unpaired electrons (Bosons), not electrons and quarks.

Rixter: electrons and quarks, neutrons, and protons (and odd particle number atoms) are all Fermions, I do not know if nitrogen really counts, but as a single atom it would be odd-numbered in protons, and also in electrons, with unpaired spins.

Bosons are field energy carriers: photons, possibly neutrinos, and such. It is suspected the Higgs-Boson is what is responsible for gravitational energy.

No Fermion microscope has existed prior to this time. Look upward and give thanks, for new horizons are upon us.

Oh. You said 'bosons'; with an n, not an m. I read that wrong the first time. I was thinking you meant something else.

There is one cheery Lassie! Are you related?

I think you are over stating this. Yes, there are some new twists, but this appears to be very similar to what I did in 1977 in a physics lab. A 400 level physics course lab had us "photograph" atoms in the lattice work of iridium. (field ion microscope) As I understand, this was first accomplished in 1955 by Dr. Mueller at PSU.

Bet they don't have the fun of developing the film from this new process after walking through a flat black painted seven section maze to get to the darkroom in total darkness as you do for the field ion microscope photos.

If I could find those old photos I'd include them.

As I understand it, a cold Bose-Einstein condensate (p~0, dp~0) means that X exists with very large dX, so that the individual particles can be almost seen with the naked eye. But your tongue will stick to the probe if you put it in there. And you will shoot your eye out with the atomic BB gun.

Here is a Quark you can see.
