One of them HATES it. - Smarter Every Day

This is so confusing to me. Presumably there should've been a way for Shane to overcome the issue he was seeing, but he completely failed to do so? If you've seen his channel, it's like 90+% troubleshooting problems! Perhaps he didn't really care all that much?

Trump Wanted Armed Groups At His Jan 6 Rally

moonsammy says...

You know, the claims wouldn't have to be "hearsay" if the parties involved (Meadows, Trump) were willing to testify before the committee. After all, if they didn't do anything wrong they shouldn't have anything to hide, right? Isn't that generally one of the right-wing mantras around justice? But Meadows at least has refused to show, and based on Hutchinson's testimony I can understand why - he's clearly up to his neck in actual crimes.

Trump Wanted Armed Groups At His Jan 6 Rally

moonsammy says...

So here's a question I find interesting: did the Secret Service technically kidnap Trump, if he didn't want them to take him where they took him? I mean, totally the correct call for them to make, but it looks like the president assaulted his own Secret Service after they kidnapped him. Which is so very, very fucked.

WORLDS OKAYEST LOG DROPPING TUTORIAL!

Guessing it's a function of rate of rotation vs acceleration due to gravity, and that 1/5th of the height just happens to line up properly for a 270 degree rotation.

I was hoping for the physics of why 20% is the number. Seems more like a guesstimate that kinda works, most of the time.

Why Russia is Invading Ukraine

moonsammy says...

Yeah, that is a LOT of good background. And I have to assume the video had been in production a while before the war started, so excellent timing!

The Fascinating Physics of Bowling

It really is a solid video. Even as a fan of Veritasium I wasn't expecting to watch the whole thing ("a half hour about frickin' bowling?!"), but sure enough...

The Fascinating Physics of Bowling

Why I Give Abortions

moonsammy says...

Really solid video. Abortion is a medical procedure which has to be available to those who need it. Until a pregnancy reaches the point of viability outside the parent, I don't see any room for debate as to whether abortion of that embryo / fetus should be legal, and entirely the choice of the pregnant person.

What *shouldn't* be legal is harassing anyone trying to access healthcare, in any context. But of course, there *isn't* any other context that I can think of where people are regularly harassed. I suppose it's been happening to some degree lately with vaccine stuff, but that's likely to be temporary (and the Venn diagram between anyone willing to harass people over vaccines and over abortions seems likely to have a LOT of overlap).

How Road Barriers Stopped Killing Drivers

moonsammy says...

Interesting - thanks for sharing! Shame it didn't work out better, and I have to wonder if the outcome would be different now with the increased focus on fuel economy / climate change mitigation.

The technical term is a rear crash attenuator.
I worked for a friend with a patent on foam cured carbon fiber manufacturing, using the heat and pressure of an expanding foam core to cure the carbon fiber without vacuum bagging or autoclaving....I helped with designing, and personally designed and built the molds, and built a number of test attenuators meant to replace the huge yellow plastic boxes on cal trans trucks. Basically an approximately 3x4x6' carbon fiber box with a dense foam core containing multiple tuned air chambers. We had to tune the chambers to stop vehicles at 60 mph without exceeding certain g forces. In the end, he lost the contract, but not because the device didn't work, I think it was too expensive, and my friend was not a great businessman. Ours was far lighter than the plastic versions, and was meant to pay for itself in fuel savings hauling it around.
