xix : Check the laws and theories of physics
… to see how many you have heard of. (The last time I ‘did’ physics was in second form.) My heard-of rate seems to be about 75%, though much better among the more astronomical ones. The comprehension rate, especially at one in the morning, is lower. And anything quantum is perfectly impenetrable.
The book is snippety and is written informally, but very ‘straight’, so I enjoyed the occasional lapse (or elevation).
In a section on the photoelectric effect, for example:
“Physicists have now also seen larger particles behaving like waves, such as neutrons … Bigger objects, like ball bearings and badgers, have minuscule wavelengths, too small to see ….”
I also concurred with the author’s reflection on the theory which would see each and every human observation of the world triggering the universe to split into two universes which are very slightly different from one another – ” … This seems a waste of a lot of good universes.”
