Anon buys an air fryer
  • Just a heads up, the ?si=... part of the youtube url is a tracker linked to you and your youtube history. Youtube will recommend people who click your link other things you watch. The ? and everything afterward can be safely removed and the link will still work.

  • The later books are really something
  • As with most sci-fi the author gets loopier in the later books. That being said:

    • Dune: masterpiece of philosophy, one of the best books ever put to print
    • Dune Messiah: a worthy sequel and must read after the first book; completes Paul's arc
    • Children of Dune: more plot driven than the first, but still thematically rich and entertaining.
    • God Emperor of Dune: the most divisive of the books: you love it or you hate it. I am in the love it camp, the book is unhinged and the themes are marvelous. This is where I'd stop a read of the series.
    • Chapterhouse and the other (Heretics?): forgettable in my opinion, simply because I've forgotten them. Later book fan opinions welcome.
    • anything Brian Herbert: not terrible but not awfully good either. Makes for decent light reading I guess, and there's good lore building in some of the books despite some unforgivable retcons (Agemmemnon, sigh)
  • Earthrise
  • I have definitely had this experience in KSP and never really thought about until this comment. Neat!

    However, there is a practical reason the Apollo mission orbited on its side like this. The side of the spacecraft facing the sun would get very hot while the side facing away would get very cold. So the spacecraft would roll slowly as it travelled for passive thermal control. They literally callrd it the barbecue roll.

    Orbiting a planet along it's equator means orienting north/south (normal/antinormal) for a natural roll axis. Neat stuff!

  • Gotta follow that rule
  • It's the last equation j(x) that's wrong. What's plotted on the right is something like 0.2x+1.6

    Your graphing calculator is more than capable of plotting linear functions just as well as desmos.

  • xkcd #2878: Supernova

    Alt text: >They're a little cagey about exactly where the crossover point lies relative to the likelihood of devastating effects on the planet.

    Tesla Has The Highest Accident Rate Of Any Auto Brand
  • Read the source more carefully

    Tesla drivers have the highest accident rate. From Nov. 14, 2022, through Nov. 14, 2023, Tesla drivers had 23.54 accidents per 1,000 drivers. Ram (22.76)

    Accidents only. Worst driver counts DUIs a d fines as well.

  • Living on the Edge Rules
  • Nobody's life is in any real danger here. They and all their equipment are roped in on at least 3 redundant anchors (probably a number more). Rock climbing looks scary but with proper precautions and training it is not significantly riskier than other outdoor sports.

    The level of ignorance from these commenters who know nothing of the sport but speak with such authority on it really reminds me of the worst of reddit.

  • Recycling program collects 43,000 pounds of e-bike batteries so far
  • Kudos to them and the 1900 participating retailers!

    Just to mention, this is the equivalent of just 42 electric cars, which goes to show how inefficient and wasteful electric cars really are. Yet governments around the world provide billions of dollars of subsidies and rebates for electric cars while fully ignoring electric bicycles.

  • Spinning a skateboard wheel so fast the centripetal force rips it apart
  • Answer: not really, no.

    What you're seeing is the result of centripetal acceleration or centrifugal force or whatever physicists feel like being pedantic about. As an engineer, all that matters is that there's a force which is pushing uniformly outwards on the wheel, which results in two types of stresses: radial stresses (which act normal to the surface of the wheel) and hoop stresses (which act tangent to the wheel). This is basically an analysis of a thin walled pressure vessel minus the longitudinal stresses.

    The waterjet provides the rotational velocity which generates the centripetal acceleration, which creates the predominately hoop stresses in the wheel. These hoop stresses are orders of magnitude greater than the minor radial stresses, which are presumably what you're imagining changing the deformation mode. So changing to another method of force application won't change the end result: hoop stresses accumulate from rotation until the tensile forces exceed the strain limit for this (presumably hyperelastic) material.

    TL;DR, the end result is the same because the global forces generated by the rotation are far greater than the local forces generated by the waterjet.
