I managed to get a quick PhD — though when I got it I knew almost nothing about physics. But I did learn one big thing: that no one knows everything, and you don't have to.

Thomson... exerted electric and magnetic forces on the rays and measured the amount... deflected.
The Discovery of Subatomic Particles (1983)
I hope the readers will let me know of any mistakes... I will post them on... zippy.ph.utexas.edu/~weinberg/corrections.html.
Cosmology (2008)
When several forces act... the total force is the sum... each component of the total force is the sum of the corresponding components of the individual forces.
The Discovery of Subatomic Particles (1983)
Under ordinary circumstances, visible light is absorbed or emitted when the electrons in an atom or molecule are excited into orbits of higher energy, or sink back into orbits of lower energy, respectively.
The Discovery of Subatomic Particles (1983)
In the ordinary moral universe … The good will do the best they can. The worst will do the worst they can. But if you want to make good people do wicked things, you’ll need religion.
Modern cosmological theories can exhibit horizons of two... types. which limit the distances at which past events can be observed or at which it will ever be possible to observe future events. These are called Rindler particle horizons and event horizons, respectively.
Cosmology (2008)
There is virtually no chance that we will be able to do experiments involving processes at particle energies like 1016 GeV. With current technology the diameter of an accelerator is proportional to the energy given to the accelerated particles. To accelerate particles to an energy of 1016 GeV would require an accelerator a few light-years across.
Finally, learn something about the history of science, or at a minimum the history of your own branch of science. The least important reason for this is that the history may actually be of some use to you in your own scientific work.

Plücker's student J. W. Hittorf... observed that solid bodies... near a small cathode would cast shadows... [and] deduced... the rays travel... in straight lines.
The Discovery of Subatomic Particles (1983)
Coulomb used a... device of his own invention, the torsion balance, to measure forces between small pith balls. The inverse-square law was found to hold accurately...
