  • do those orbits get larger over time?

    Yes, I think they do.

    I think that expansion doesn’t increase distance, but velocity between objects (or so was my interpretation back when I looked at the formulas). That means that moving objects speed up over time. As such, orbital velocities increase, too, and that lifts their orbit - similar to when a rocket on a closed orbit propulses forward.

    But I might be wrong; I feel 70% certain about this one.





  • Currently in a very inter-disciplinary field where the different mathematicians have their own language which has to be translated back into first software, then hardware. It’s so confusing at first till you spend 30 minutes on wikipedia to realize they’re just using an esoteric term to describe something you’ve used forever.

    Yeah, this happens a lot. I studied math and I often got the impression that when you read other researcher’s work, they describe the exact same thing that you have already heard about, but in a vastly different language. I wonder how many re-inventions and re-namings there are of any concept simply because people can’t figure out that this thing has already been researched into. It really happens a lot, where 5 people discovered something, but gave them 5 different names.


  • Oh i would say “ring” is in fact quite a descriptive term.

    Apparently, in older german, “ringen” meant “to make progress of some sort/to fight for something”. And a ring has two functions: addition and multiplication. These are the foundational functions that you can use to construct polynomials, which are very important functions. You could look at functions as a machine where you put something in and get something out.

    In other words, you put something into a function, the function internally “makes some progress”, and spits out a result. That is exactly what you can do with a “ring”.

    So it kinda makes sense, I guess.


  • A big reason why newspapers use so many filler-phrases and redundancy and just don’t get to the point is because journalists often get paid for how much they write; The consequence is obviously: filler-words.

    Getting paid for “how much they write” may be implicit. For example, the boss might look at what the employees produce and say “ok this employee is good because they wrote 30 pages, this employee is bad because they wrote only 5”. Even though they might get a fixed salary/month, the one that writes few pages might get fired.











  • Cooking rice is a notoriously hard problem (and for that reason I recommend noodles instead) but my tip is:

    • Don’t (!) do the 2:1 thing where you mix 2 cups of water with 1 cup of rice. Some of the water will boil off and the ratio will be distorted, except if you close your cooking pot, in which case it begins to foam like crazy and give you something to clean up
    • Do just fill a large pot with lots of water and make it boil; then when it boils add the rice and cook a certain time with the pot open. I’ve made the best rice this way.
