Obtaining patent protection for inventions including chemical features has important differences from other subject matter, such as different standards of predictability in the application of prior art. Learn how to maximize your chances of obtaining broad protection.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Errata and notes:
1. I got the Oxidising Agent and the Reducing Agent the wrong way around! Sodium is the Reducing agent and Chlorine is the Oxidising agent. My confusion was that when a sodium atom looses an electron it becomes oxidised, so in my simple brain, I called it the oxidising agent. That is wrong because the agent that oxidises the sodium is the chlorine atom and so the labels are the wrong way around. Doh!
2. I drew the hydrogen H2 molecule with a double bond but it should be a single bond because they are bonded with a single covalent bond.
3. Where I have drawn carbon dioxide, the carbon should have a double bond to each of the oxygens.
4. Apparently Feynman diagrams are not that useful for theoretical chemistry, so perhaps that wasn't the best choice for the illustration. The feedback in the comments from a real theoretical chemist is "All we deal with is shuffling around electrons, but many many many electrons, so a Feynman diagram would need to be huge but at the same time would be very very repetitive."
5. In analytical chemistry, I should have called it distillation rather than precipitation.
6. My definition of organic chemistry being about ‘life’ is not very good. I should have said that organic chemistry looks at compounds that contain carbon. But there are some compounds in inorganic chemistry that also contain carbon, like carbon dioxide so I guess I'd also have to state that inorganic chemistry is almost everything else.
7. I said that fuels are inorganic chemistry which is misleading when I drew a car next to it. My understanding is that there are inorganic fuels that don't contain carbon, but obviously all the fuels we are familiar with are organic. I thought a picture of a car would tie a few things together elegantly, but it ended up giving the wrong impression. That’s okay, I’m still learning! :D
8. In inorganic chemistry, I should have stated that all natural minerals fall under inorganic chemistry so as not to be misleading, otherwise you might go way thinking that only man-made substances fall under inorganic chemistry which is not true. I said that 'a lot of the inorganic compounds that are studied are man-made' meaning that the cutting edge of research is mostly man-made substances.
9. Apparently water is not the most inflammable substance. I thought it was so that is interesting.
10. In the bonding section, hydrogen bonding and van der waals forces are technically inter molecular forces.

In this video, we start looking at waves. We explore the key differences between transverse and longitudinal waves. We then look at how when a wave travels, the wave moves but not the medium.

A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor https://brilliant.org/dos
I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation. Let me know if it was helpful! Cheers Dx

Further reading
For a more detailed introduction to quantum physics: 'The Quantum Universe' by Brian Cox and Jeff Forshaw is good.
And a slightly more advanced but fantastic description of what we do and don't know about quantum physics is the excellent book 'Beyond Weird' by Philip Ball.
