There's been a lot of news about gas stoves. At first, I was skeptical about the panic over these appliances. But then I measured the indoor air pollution from our stove and talked to public health experiments.

You can view all sources, learn more about my experiment, and listen to behind-the-scenes interviews on the Distilled website: https://www.distilled.earth/p/i-measured-the-pollution-from-my

ALL OF PHYSICS in 14 Minutes: https://youtu.be/ZAqIoDhornk

Everything is made of atoms. Chemistry is the study of how they interact, and is known to be confusing, difficult, complicated...let's learn General Chemistry in under 20 Minutes.

This is not ALL of Chemistry, as fields like "Organic Chemistry" deserve videos of their own. But, this is the foundation, or "General Chemistry", which contains most concepts you need to know to understand other topics and fields of Chemistry.

This is a summary and revision of around 4 years of Chemistry you learn in school, with maybe some university level concepts sprinkled in the mix.
This video is a good summary for preparing for exams and finals. Maybe. Perhaps.

Now go learn all of Chemistry. And share this with your friends who suck at Chemistry
