Organic chemistry is pretty much everywhere! In this episode of Crash Course Organic Chemistry, we’re talking about the amazing diversity among organic molecules. We’ll learn about the origins of organic chemistry, how to write Lewis structures, condensed structures, and skeletal formulas, and what gross organic compound the Romans used to dye their fabrics pretty colors.
When you look in a mirror, and see what you think is a perfect reflection. You might be looking at a universe whose laws are fundamentally different.
Quantum mechanics tells us that the atom’s wavefunction can be in a superposition of states – simultaneously decayed or not decayed. So is the cat’s wavefunction also in a superposition of both dead and alive.
Physicists have been struggling for some time to figure out why our universe is so comfy. Why, for example, are the fundamental constants – like the mass of the electron or the strength of the forces – just right for the emergence of life? Tweak them too much and life, stars, galaxies, the universe as we know it wouldn’t exist.
