How does one detect an atom?
)
September 26th, 2011
With last week’s news about the speedy neutrinos from CERN, a question that I have had for ages came back to mind again:
How does one detect an atom?
Obviously there was a first time that someone went home after work and told his/her spouse “Dear, I found an atom today!”
But how?
A microscope?
Did he/she had to cut the material with a knife in very small parts first?
To someone who knows, explain it to me in simple words imagine I am your old aunt, please.
If there is some time left: same question for the neutrino, the (almost) undetectable part?
Using Fluther
