Atoms, Electrons, Protons, Neutrons, Quarks, Gluons, Strings

An article in Life Science included a very simple diagram of many well-known subatomic particles:

Surrounding the nucleus of an atom is a cloud of very light electrons.

The nucleus consists of two types of hadrons – a proton and a neutron.

Like all hadrons, the proton and the neutron contain three quarks plus the gluons that bind them together.

The proton and neutron contain the two most common quarks – “up” and “down”

According to string theory, all these particles are composed of very small strings

The diagram above gives a misleading idea of relative sizes.

Each step to the right shows particles many orders of magnitude smaller than the ones to the left.

  1. Well, now I understand a lot. My friends have always told me I am “quarky” and I “had on n attitude” so it must be that I have had too much “proton” for breakfast (I am on Atkins so proton is a requirement). Now, John Mallon on the other hand is always standing “up” for the Chicago Manual of Style or “down right confused” about what is being said, so he must be “quarky” too.
    I never thought science was my thing, but you have set me straight – have you been “stringing” me along all this time? I appreciate this very interesting, simple, explaination. You are very good at teaching and I appreciate that quality.
