I'm a medical doctor, and this is the first time that I heard about the connection between the "beauty" of consumption, fashion and the fascination for being "skinny".

Is there a resource that cites the illustrations? I remember the standard oil octopus from my high school text. I’ve always thought that it looked cool.

Found it. The stanard oil octopus was by Joseph Keppler.

This series is awesome ❤ Does other countries have "Museum passes"? Here in Finland there is a pass (around 60 euros/year) that you can use to get in almost every museum in the country. There is lots of private ones included.

Watching in 2024. Hearing John speak about disputed electoral college votes and congress deciding the election fills me with dread. Stan can we get the foreshadowing filter?

Ha! I'm laughing. 😂 People commenting on the high energy and fast paced edits don't realize that was the "RU-vid Style" at the time this was recorded. Good times.

"Invalid" just means "not strong". You can apply the term to logic and millenial slang, but in the context of illness it's just "not strong".

Such a great video, thank you! As someone who studies tuberculosis, especially in cows, I would only add a comment about TB being a zoonotic disease, which means it can also spread from animals to humans, making its control very important among animal populations.

The number of picoseconds in a single second is approximately the same as the number of seconds in 31,689 years. That's how small a picosecond is

I was going to ask why the universe didn’t immediately collapse into a black hole. Good to know that isn’t answered yet due to not understanding quantum gravity.

Love this so far. It's the only thing I've been able to focus on with real curiosity. I have a question. Regarding the so called "Golden planets" that we believe may be habitable for humanity, given that they share a similar atmosphere, wouldn't we be observing these planets from millions of years ago? How do we know they still may be habitable?
