  8. Dynamite, specifically, is an explosive composed of nitroglycerin absorbed in diatomaceous earth. It's actually well known for being unstable and subject to shock detonation. According to Wikipedia, "Dynamite is moderately sensitive to shock. Shock resistance tests are usually carried out with a drop-hammer: about 100 mg of explosive is placed on an anvil, upon which a weight of between 0.5 and 10 kilograms (1.1 and 22.0 lb) is dropped from different heights until detonation is achieved.[8] With a hammer of 2 kg, mercury fulminate detonates with a drop distance of 1 to 2 cm, nitroglycerin with 4 to 5 cm, dynamite with 15 to 30 cm, and ammoniacal explosives with 40 to 50 cm." This is a huge improvement over raw nitroglycerin, and is enough to make dynamite "safe enough" for peacetime use, especially with the lower workplace safety standards of the past. If you think that dynamite is very stable and shock-INsensitive, you're probably thinking of TNT, which popular culture commonly confuses with dynamite since they're both high explosives available in stick form. TNT is so stable that . . . well, here, let me quote Wikipedia again: "TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate and because it was less powerful than alternatives. Its explosive properties were first discovered by another German chemist, Carl Häussermann, in 1891. TNT can be safely poured when liquid into shell cases, and is so insensitive that it was exempted from the UK's Explosives Act 1875 and was not considered an explosive for the purposes of manufacture and storage." TNT and dynamite are considered synonyms by Looney Tunes, but they're different substances with different characteristics. Now you know, and knowing is half the battle!
  9. You're looking at footage of Potentially Hazardous Asteroid (52768) 1998 OR2, taken on April 24 of 2020, between 8:37 PM and 9:14 PM (UTC). It's notable because "It is one of the brightest and therefore largest potentially hazardous asteroids known to exist," and also because "According to observations by the NASA IRTF telescope during the ExploreNEOs Warm Spitzer program, 1998 OR2 is a rather rare L-type asteroid." L-type asteroids are distinguished by their reflective spectral profile, although I can't work out what that means in terms of what they'd look like to human eyes. (52768) 1998 OR2 does not appear likely to actually hit the Earth in the near future, according to the data we have now. On April 16, 2079 it will pass Earth at a distance of roughly 4.6 times the Earth-moon distance. Space contains many objects moving around with enough energy to cause mass destruction (on a human scale) and we survive mainly because space is mind-bogglingly huge (on a human scale) and also because Jupiter's influence protects the inner system.

    We've known that this is how planets form for some time now, but it's still awesome to finally have pictures of it!
  12. You've got it on your hands. You don't have enough of it. You've got it on your side. You're pressed for it. You spend it. You waste it. It's in. It's out. It's now. It's past. It's running out. It's drawing near. Chrono Trigger. It's about time.
  13. I'm kind of more impressed by the thousands of dollars worth of Heroscape tiles.

  15. I'm a little unclear on how a sack of flour is dangerous, but I agree with pawsplay in principle. Firearms are, I suppose, kind of easy to use for mass killings, and in this country they definitely have some weird status as a symbol of . . . I dunno, toxic masculine power and virility or something. America has an unhealthy relationship with firearms, that's for sure. However: Anyone, on any side of the issue, who thinks that firearms are the best way to kill a bunch of people simply lacks imagination. For obvious reasons I'm not going to describe better ways to kill people, but in the timespan of a single cup of tea, I could come up with half a dozen ways to cause mass casualties that wouldn't require much technical skill and would be safer for me. Anyone who thinks that banning AR-15s is going to make the country safer is falling for the false promise of a quick and easy solution to a complex and difficult problem.

  17. It's time to stop asking nicely and start making the government do its damn job of caring for the citizens.
  18. Yeah, the line between "long dagger" and "short sword" is kind of blurry.
  19. I note that swords are not on that list. But, like pawsplay said: "Daggers, though. You can always find a justification for a dagger."
  20. I'm a liberal gun owner (yes, we exist) but I don't really like to associate with other gun owners because of this stuff. I don't understand why enjoying some dangerous toys has to come bundled with . . . all those problematic political views.
  21. I can see why you'd worry about that. I was a pallbearer for my maternal grandmother not that long ago and . . . yeah, it feels like something you don't want to mess up.
  22. Hmm. This appears to be a person Not to be Plucked With, if you'll pardon my non-cooking-related French.
  23. Evacuate the hurricane area . . . and bring your house with you!
  24. Yeah, it's . . . depressing to realize how much this can affect us and how little we can do about it as individuals. I may do a little "prepping". I live in the Cascadia Subduction Zone, so preparing for a disaster is already something I should be doing.
  25. Governments can declare things open all they want, and when they do, the working class lose their unemployment protection. The working class people who had been sheltering in place and getting by then have to choose between financial disaster or risking their lives for a paltry paycheck. The drive to "re-open the economy" isn't coming from people who want to go back to work. It's coming from the rich, who want money flowing into their already overstuffed coffers faster, and from the entitled, who want other people to risk their lives for their own convenience.
