:In the early 20th century atoms was in some respects believed to behave similar to solar systems, in that electrons orbited around the core of the atom like planets orbit around their sun. Nowadays, it has been discovered that electrons do not orbit around the core of the atom in such a manner; rather, the position of electrons are described with a more complicated model involving so called orbitals and probabilities. However, planets are still considered to orbit around their sun. The joke in this comic is that it claims the opposite: that atoms are still imagined with electrons in simple orbits, while planets have turned out to move according to the more complicated model with orbitals and probabilities. If this is amusing, it is probably because it is an absurd thought that something as big as planets would move in such an unintuitive way, which can not be described with classical mechanics. It may also be amusing that the history writing in the comic is very similar but opposite to the accepted one. | :In the early 20th century atoms was in some respects believed to behave similar to solar systems, in that electrons orbited around the core of the atom like planets orbit around their sun.

When I first read the comic, I was confused about Randall (Ms. Lenhart) describing quantum orbitals correctly. See, I knew the real history of science, so my brain autocorrected it to read that we used to think electrons had elliptical orbits. I had to look three times before I even saw the inversion.

Someone should add something about Lyapunov time, and how orbits are unpredictable on longer timescales.162.158.146.175 16:59, 10 December 2022 (UTC)

Someone PLEASE explain this to me like I'm five? The explanation confused me :(
- In the early 20th century atoms was in some respects believed to behave similar to solar systems, in that electrons orbited around the core of the atom like planets orbit around their sun. Nowadays, it has been discovered that electrons do not orbit around the core of the atom in such a manner; rather, the position of electrons are described with a more complicated model involving so called orbitals and probabilities. However, planets are still considered to orbit around their sun. The joke in this comic is that it claims the opposite: that atoms are still imagined with electrons in simple orbits, while planets have turned out to move according to the more complicated model with orbitals and probabilities. If this is amusing, it is probably because it is an absurd thought that something as big as planets would move in such an unintuitive way, which can not be described with classical mechanics. It may also be amusing that the history writing in the comic is very similar but opposite to the accepted one.
