Chemistry is defined as the study of energy and matter and how they interact with each other.

“chemistry in general is the study of energy and matter and how they interact with each other”

The internal staining in the Red Pyramid is evidence of chemical residues from industrial production rather than biological waste from bats.

“the conventional explanation is that the extrusions because it looks like drips coming out of the stone itself and the conventional explanation is that this is from the bats inside of the structure that have some sow caused this staining all over the walls of the chamber and that the smell of ammoni”

Genetically encoded chemistry offers a vast, unexplored space for discovering new chemical catalysts.

“The space of non-natural chemistry is way bigger than the universe of nature's chemistry.”

Rudy found organic chemistry to be an incredibly difficult class that caused her significant stress.

“during the spring semester I was taking organic chemistry and I hated that class so much like I kept getting C's so you get degrees yeah don't forget and I thought I was gonna fail and so I was really stressed so that's how I cut my hair because I need needed like control”

Human cells cannot utilize cholesterol as an energy source, which is an evolutionary design to protect essential cell membrane and hormonal components during fasting.

“I think it's actually a very deliberate design quote I use design in quotes to say hey no matter what your cholesterol and your hormones are off-limits during starvation”

External particles like dust or fibers can accidentally seed the crystallization of different polymorphs in pharmaceutical manufacturing.

“Even if you have a seed crystal, if there are some dust particles or some scratches in the recipient where actually crystals can start to nucleate, that can induce, then, different crystal structures.”

Neil deGrasse Tyson agrees that the periodic table of elements is consistent throughout the universe based on spectroscopic evidence.

“we get we look at Spectra of Stars galaxies Across the Universe and the Spectrum matches what we can produce in the laboratory for the various chemical elements so you look at like what carbon looks like sort of when you burn it in a lab and it has a signature in the Spectrum and you find that same ”

Cesium is highly reactive because it is a large atom with loosely held outer electrons that are easily pulled away by oxygen.

“cesium is really big. And what that means is it has a very very positively charged core. its nucleus, but its electrons are very far away. So, it can barely reach the electrons. And so, because it's so big and their charges are so separated, oxygen, which likes to take electrons from a neighbor, it ”
