  • Yep! Same thing with black holes which are not holes at all!

    Even very basic physics terms such as positive and negative electric charges lead to a lot of confusion for ordinary people. There’s nothing positive or negative about them, they’re just names for the fundamental property of protons and electrons that leads them to attract one another.


  • Employers are inherently ableist. They discriminate against people who are unable to do the job. They also discriminate for reasons unrelated to job performance, but then measuring job performance is very difficult even when someone has been working at a company for years.

    Note that in professional sports and in Hollywood it’s quite easy to measure performance. Accordingly, you see athletes and actors compensated in a way that’s much more in line with their job performance than other industries.


  • I think a lot of the confusion people have is around the word “observation” which in everyday language implies the presence of an intelligent observer. It seems totally nonsensical that the outcome of a physics experiment should depend on whether the physicist is in the lab or out for a coffee! That’s because it is!

    I have this beef with a lot of words used in physics. Taking an everyday word and reusing it as a technical term whose meaning may be subtly and/or profoundly different from the original. It’s a source of constant confusion.


  • I absolutely miss the experience of walking around local video stores (Blockbuster being the last of these). Compared to the experience of searching for a movie on Netflix and the damn thing trying to gaslight me into forgetting what I searched for?

    Yeah fuck off! I’ll take plain old shelves any day! I can see what they have and what they don’t have! I can also talk to the people who work there (often big movie fans) and get recommendations from a real human being who can explain why they like a movie rather than just “people who liked this movie also liked that movie.”






  • All the spatial persistence stuff was handled by the desktop database which was an invisible file that got stored on the disk. Hard drives and floppies each had their own so that if you shared a floppy with a friend the spatial properties of the floppy would travel with it. This also worked if you moved a hard drive from one system to another for the same reason.

    It also worked over AppleShare network file sharing. Where it didn’t work was if you had 2 different computers since there was no way to sync information between them. You essentially treated each computer as its own thing which is really more in keeping with the spirit of spatial design. After all, it would be really weird if 2 different drawers in different rooms in your house somehow always had identical contents which stayed in sync.


  • Q for all those with suggestions: do any of these attempt to replicate the Spatial Finder? No other system I’ve seen (contemporary to OS 9 or since then) seems to have got this element correct (or even attempted to do so).

    It’s such a key part of the OS 9 (and earlier) experience. Double click a folder and it opens where you expect it to, in the shape you left it, with the icons laid out as you left them. It’s a method of working that gives you great familiarity and confidence.

    If anyone’s worked in a kitchen or workshop for a long time and developed a deep memory for the layout and the location of every tool, material, and control, then they’ll know what I’m talking about. You can move around and work incredibly efficiently, relying greatly on muscle memory.

    Since the demise of OS 9, the only way to retain this level of operation has been to rely heavily on the keyboard. Since almost everything on the screen is transient and unreliably positioned (non-spatial), only the keyboard is persistent enough to allow us to work at the speed of thought and rely on muscle memory. It’s been so long now that I think people forget (or never knew) that the contents of the screen could also be persistent and spatial this way.
