389. The Acid Test: Theories of Matter

Posted on 30 January 2022

Schegk, Taurellus, Gorlaeus, and Sennert revive atomism to explain chemical reactions, the composition of bodies, and the generation of organisms.

You'll never get away with your joke about William of Orange/ fruit salad!

All physical quantities almost certainly come as a sum of quanta. For example, it is well established that amount of energy, and the amount of positive and negative electricity are all sum of quanta and the same probably goes for mass, because mass and energy are equivalent.

Furthermore, let's for example consider length. We take for granted that this physical quantity is finite, so it's paradoxical to say that something with a property of finitude can be divided an infinite number of times.

I remember the article on the Stanford Encyclopedia of Philosophy (forget the name of an article by now) where some topic concerning modern physics was discussed. At one point three physical constants together with their corresponding units were multiplied (that result must be constant also). The result was a very small length in meters. Nobody knows what to think about it, but some speculate that obtained result is a likely candidate for a quantum of length.

At minute 03:27 of your talk you give a Latin expression attributed to the scholastics ...Could you kindly transcribe it and if at all possible give a book reference... Thanks in advance

Sure! It's: in quae dissolvi possunt composita, ex iisdem coaluerunt: “the things into which composites can be dissolved are the things out of which they are made.” I got this from W.R. Newman, “The Significance of ‘Chymical Atomism’,” Early Science and Medicine 14 (2009), 248-64, at 255.
