Reading Books about Physics

It’s not unusual for me to go through a phase of reading about the particles and forces that make up our universe.

I have one measure to prejudge the author’s content, though. Is there an entry in the index for ‘plasma’?

Plasma is a state of matter just as solid, liquid, and gas are. At high energies, atoms lose some coherence and separate into positive and negative ions. Freed electrons and negatively charged particles can flow like electricity.

In our experience, electricity flows through wires. The flows in the plasma state resemble descriptions of liquid flows. For us, the most common flow of a liquid is flowing water.

Apparently, there is an affinity between studying fluid dynamics and studying plasma physics.

I’ve written the previous three paragraphs as a layperson who has some understanding but plenty of misunderstanding about the subject. Be that as it may –

About 98% of the universe exists in the plasma state.

Nevertheless, authors of popular works about physics often fail to mention the subject of plasma altogether. I take a look at the index of such books and regularly find an entry for ‘Planck’ followed by an entry for ‘Plato’ or ‘Pluto’. What this tells me is that the author is married to an orthodoxy.

“The primary force in the universe is gravity.” Really? Perhaps electromagnetism is as important if not more important.

Granted that us Earth-bound creatures a very aware of gravity. Granted that the human race had little knowledge about electricity until fairly recently. Certainly, using electricity was not part of the human toolkit until recently.

I expect more from physicists. Their orthodoxy is earth-bound where gravity prevails – unless a lightning storm is passing through.

I look forward to a time when earth-bound physics is as outmoded and quaint as saying scientifically that the Earth is the center of our solar system or not.


Geocentricism is a tenet of the Torah, of religious revelation. According to the theory of relativity, though, no scientific verification exists to determine if one body is stationary and another is moving, or vice versa, or that both are moving.
