  • if your heartrate is a lot above 60 bpm you should do more exercise, then the pulse slows down. a fast pulse rate is often associated with not getting enough physical exercise.

    healthy pulse is considered 60 bpm to 90 bpm. some argue 60 bpm to 75 bpm is the green range, while 75 bpm to 90 bpm is the yellow range, while above 90 bpm is red.

  • yeah ikr but why is the second 1/60 of 1/60 of 1/24 of a day? early people in antiquity could have made it 1/60 of 1/60 of 1/60 instead, or just 1/60 of 1/60. What inspired people to divide the day that way?

  • The SI system is also based on the length of body parts though

    The second is the length of a single heartbeat. During one heartbeat, the heart muscle consumes 1 J of energy, which makes 1 J per second, roughly, which is 1 W.

    Also the 1 m is the length of the spinal chord. Some might not get the significance of the spinal cord and that's fine but it's the central canal in the body so there's that. Edit: yeah yeah i get it it's not the "official origin". However i remember reading a paper where they discussed that the meter should be the length of the spine, but they didn't outright wanna say it, so they searched for a natural circumstances that just so happened to approximate that.

    Also i believe that 1 kg is what you can comfortably carry. Or about the amount of food (cereals) that a worker gets paid for a day of field work. Compare to japanese Masu.

    NASA fired up a prototype of its electromagnetic thruster inside a vacuum chamber, reaching power levels of up to 120 kilowatts—the highest achieved in U.S. tests of an electric propulsion system

  • What matters is the effective exhaust velocity. For chemical rockets it's 3 km/s. The article doesn't seem to mention it?

    On top of that, ion drive travel is notoriously slow. So it's not good for human travel because you would need more life support system for the longer journey, including more food and water, which makes the rocket heavier and is thus undesirable. It would only be useful for cargo transport where it doesn't matter whether it spends 6 months or 3 years in space.

  • lifting a 100g schoko 1 meter per second, on Earth

    in space no because there's no gravity, so lifting things doesn't take energy, only acceleration does. too lazy to calculate now, the relation is simple but i'm lazy.

  • uhh, i doubt that. at least as long as the company has a sane core business, it's stable long-term (or rather goes up with the general economy). it can't "go down more than it goes up" on average.

  • thank you :-)

    i feel like this message is finally getting through. many people say "work is good" because they think it "purifies character" or sth, which is a very christian/boomer thing to say.

  • where your pension fund is being traded and i bet you would care slightly more about that.

    no not really. as long as i don't sell, it doesn't affect me if it goes up and down all the time.

  • no. like, the term "working class" can be interpreted in two ways: (1) people who are inherently workers, (2) people who are forced to work to survive.

    which one is being replaced?

  • insider trading can only make money if somebody bets against it. i think as long as nobody bets against it, it should be fine (as it doesn't actually generate any profits).

  • I'm on discuss.tchncs.de right now and its web UI lags badly probably due to a lot of bot scaping.

    If we had Anubis i guess that could be avoided.
