  • Damn, are you me? I haven’t bothered with fading out the back yet, but I also cut 12mm on top, 9mm for the rest.

    Personally, I found that when I lean my head back, then there’s a pretty noticeable bend where my neck starts. And when my hair crosses that line, it looks bad. So, that’s where I create the border.
    And I just basically grab the back of my skull and move my hand down until it meets that bend to the neck, then I cut along the index finger.
    I feel like I’d probably create the fade above that, too, but your mileage may vary, of course.





  • I’m saying spray-mop the floor once a week and you’ll take most of the dust out of that room before it settles on harder-to-clean surfaces, which reduces how often you need to clean shelves, plants etc…

    Most dust in a typical household is from shed skin cells, from either humans or pets. And I do imagine that most shed skin cells just fall onto the floor at first and can be collected there.

    I’m no expert. I probably know too little about the propagation speed of a wave to understand what you mean there.

    But here is a scenario where something is faster than light in the given medium: https://en.wikipedia.org/wiki/Cherenkov_radiation

    As I understand, neutrons and gravitational waves are also bound by the speed of causality, because they have no mass. And I believe, unlike light, they are unaffected by electromagnetic forces that a material exerts, so they would presumably (always?) travel faster than light in that medium.

    I will also say, that from what little I understand of this video: https://www.pbs.org/video/pbs-space-time-speed-light-not-about-light/
    …it sounds like trying to determine the speed of causality by measuring it, is kind of backwards. You’re at best experimentally confirming what has to be a given under our laws of physics.





  • That’s kind of why I never feel great about buying video games. The price is pretty much entirely arbitrary.
    Like yeah, they did an investment, it is fair that they recuperate that. But the actual price they need to ask of each customer entirely depends on how many customers there are.

    And so, they will always start out asking more than what they expect to need to ask of each customer, which just feels like I’m paying too much.
    But even when they do put it on sale, there’s likely going to be sales in the future where they sell it for even less. It’s not like they need to empty out a warehouse or such, where they put up uniquely low prices. So, even when I could get a game on a sale, I’ll feel like I could also just wait longer…



  • She did the math (with some assumptions), but basically 0.25 mL of lemon juice will turn 500 mL of alkaline water into neutral water:

    This is in the video at 13:16.

    The reason is that pH is a logarithmic scale. Alkaline water has a pH of about 8, which means it has a tenth of the hydrogen ions compared to neutral water at pH 7.
    Lemon juice has a pH value of 2, which is 1,000,000 times more hydrogen ions than there are in pH 8. So, you just need a little bit of lemon juice to increase the hydrogen ions in alkaline water tenfold, which makes it neutral.




  • Kann mir so gar nicht vorstellen, wie das hätte anders laufen sollen. Im Grunde gehe ich davon aus, dass Trump demokratische Wahlen abschaffen will, lediglich deshalb, weil seine Politik so gar nichts bietet, was man wiederwählen wollen könnte.

    Man muss schon krasser Menschenfeind sein, um die ICE Raids gut zu finden. Und ja, der Ballroom wird vermeintlich über Korruption statt Steuermittel finanziert, aber man hätte auch etwas Nützliches damit finanzieren können. Oder stattdessen reale Probleme angehen.
    Wenn man Trump gewählt hat, in der Hoffnung, dass er Probleme löst, dann darf man ja im Grunde nie Fox News abschalten, sonst wird die Illusion recht schnell zusammenfallen.
