Grumpy Professor Hank admits to being wrong about how everything is chemicals. But he now wants you to listen as he blows your mind with a new sweeping statement: everything (yes, really everything this time) is energy. What! This week, Hank takes us on a quick tour of how thermodynamics is applied in chemistry using his toy trebuchet as an example, because he is a proud nerd. Pssst. we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

There are two categories of energies, intrinsic energies and extrinsic energies. Intrinsic energies are the energy that embedded within the atoms themselves such as gravitational energy, electrostatic energy and magnetic energy. Whereas extrinsic energies are energies due to the changes to the stockpile of photons. Changes in extrinsic energies also can affect the intrinsic energies because photons are negatively charged particles and also enveloped with intrinsic magnetic field. Einstein's famous equation, E=mc-2 is wrong otherwise garbage also can be used to make nuclear bombs as long as it Is matter or it has mass. Energy and matter can't interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. All forms of EMWs including light and heat are dynamic photons per volume per time in different saturations. Chemical energy is dealing with the changes in stockpile of photons. Exothermic reaction where atoms dissipate out photons to the surroundings. Endothermic reaction where atoms absorb photons from the surroundings. Precisely, the stockpile of photons onto those nucleons is changing during chemical reaction. Therefore the flexure of the nucleus structure of an atom is experience change before and after chemical reaction due to changes in their stockpile of stationary photons. Different flexure of nucleus structure of an atom will re-orientate its edgorbtoslengths or orbitals that leads to different in sharing electrons between atoms. Thus, an atom will have different physical and chemical characteristics before and after chemical reaction. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

Hank -- At 2: 06, you said -some of [the bonds inside the wood that contain energy] could be broken, releasing that energy- but I wanted to point out that that is backwards. It takes energy to break bonds, and if you burnt up your trebuchet, the atoms whose bonds were broken would form new bonds, specifically ones that have less energy than they do in trebuchet-form, and that is where the energy of the fire comes from.
Thanks for everything you did and continue to do.

Glad to know I-m not insane for thinking that (almost) everything is made of chemicals. Just because you can-t pronounce it doesn-t mean it-s evil. Just. sound it out and move on with your life; )

If you think Hank speaks too fast, try watching the video at 2x speed. True me, he will seem much slower when you come back to your senses and listen at normal speed -

out of all of the different crash courses, Hank's has got to always be my favorite, the references and generally just the way he speaks is prone to never get me bored.

-The amount of everything in the universe is constant-. so there is only essentially one thing or infinite things. pick one doesn't matter, its just matter.
