    I still remember the way my science teacher explained a hypothetical warp drive (like how it is in Star Trek). He took a black towel, representing space, and laid it flat on a table. He set down a miniature model of the Enterprise on one end of the towel, then accordion-folded the towel up so that the other end was close to the ship. He moved the Enterprise over to that end of the towel, and unfolded it so that it was flat again. The Enterprise was now on the other end of the table.

    An overly simplified visualization, but it really illustrated the idea to my ten year old brain how space-time could hypothetically be bent to make fast interstellar travel a possibility. Also it made me realize that warp speed on the Enterprise wasn’t just a super powerful rocket or something.


  • Before Louis Pasteur’s disproving of spontaneous generation, most people believed that bacteria and putrefactive organisms like maggots etc. spontaneously poofed into existence, like a video game character spawning. Pasteur suggested that maggots came from flies laying their eggs on rotting meat etc, and that bacteria were everywhere and will multiply quickly under the right conditions. A lot of people at the time thought these were crackpot ideas.





  • I wouldn’t say “completely fucked”, but for a few years I noticed YouTube on Firefox has this occasional quirk where videos will quit playing and infinitely buffer at the exact same timestamp. Like there’s no way around it except skipping about 30 seconds ahead with the seek bar, or doing a Ctrl-F5 (hard refresh) and starting the whole video over. Opera GX doesn’t seem to have this problem at all.

    But it’s still not a big enough deal to make me give up Firefox completely.



  • That being said I don’t have memories of everything being snappy 20 years ago - there were messy scripts and gigantic images that made Geocities and Angelfire sites near unusable back then as well.

    Pages with dozens of embedded JPEG files that are larger than your monitor’s resolution and are compressed at highest quality. Easily a quarter to half of a megabyte each and take several minutes to load on dialup, then the webserver times out the connection because you’re taking too long to download all these giant files at once.

    I don’t miss those days. Not to say things are better now, but they necessarily weren’t back then either.

    Oh, and RealPlayer. Fuck RealPlayer.

    I always use seconds as an allegory to dollars when I explain to people the difference between thousand, million and billion (I did the number crunching in my head and rushed it, so if I made any errors lemme know).

    1000 seconds = 17 minutes

    100,000 seconds = 27 hours

    1 million seconds = 11 days

    1 billion seconds = 31.70 years

    148 billion seconds (Bezos’ net worth) = 4693 years
