I have watched this man explain the refrigeration cycle, where he dicusses what latent heat of vaporization is in so many videos, so many times over, and I still could not tell you how it works.

But that doesn't mean he's not good at explaining it, it just means I have too much of a caveman brain to understand it.

This is definitely one of the best YouTube channels. I should probably consider being a patron, tbh.

I don't know much about trading stock, but I do know SpaceX is not a publicly traded company. That means his buyers for those shares are super limited, so each potential buyer would likely be super wealthy and would have more say over the company than any one individual in the horde of public buyers that would buy up the Tesla stock. Plus, him needing to divest from Tesla might actually drive Tesla stock up a little (eventually), since he won't have as much control of the company as he did before. It seems he would still be the largest shareholder after the selloff, but this would close the gap between him and the next largest shareholder. He owns over 3x more Tesla stock than the next largest shareholder.

This bridge was probably also designed to account for thermal expansion to a certain degree. It seems like more and more of our infrastructure is starting to fail, encountering heat levels it was never expected to encounter. I wonder if failures like this and worse are going to become a common headline

Bridge engineer here (not much experience, so I wouldn't consider myself an expert, but I have more knowledge about it than the general public).

Your suspicions are correct, bridges are designed for thermal expansion. More of our infrastructure is starting to fail, and part of that is because it's experiencing climate it was never designed for (heat, sea level rise, more drastic storm surges, etc). I would fully expect this to be a more common headline. At least for several more years, anyway. If the federal money from the infrastructure bill the US passed a few years ago runs out or is not allocated to the right structures, then this will only get more common. I don't expect the Trump administration to champion an extension of these funds if they do run out. It was passed under Biden, after all.

As for this bridge in particular, this is a moveable steel bridge. The fact that it's moveable means it is particularly sensitive to expansion (as well as salinity which causes rusting). Too much expansion, and the steel will get stuck in one position. In a typical steel bridge, if the thermal expansion exceeds what it was designed for, you end up getting higher stress levels in the steel as it pushes harder against the abutments. Usually this is alright in the short term, since we design these to withstand much higher stresses than it will ever likely experience. Repeated cycles of this, however, will cause fatigue failure (think of a paperclip or metal spoon snapping after you bend it back and forth a bunch).

Anyways, there you have it. I rambled for too long about this lol.

I can still remember the gen 1 starting pokemon, anyway.

Let's see, there's Squirdis, Barbarasoar, uh... Chortle? Oh no

Yeah, the ones who hired a teacher without doing any sort of a background check are the ones who really should be fired. Imagine if they hired someone who was actually dangerous to their students.
