Technology@lemmy.world•28-pound electric motor delivers 1000 horsepowerEnglish
21·3 days agoYep, I noticed that, you’re right. And that’s near-miraculous efficiency. The maker’s website sez: “YASA also estimates that its all-important continuous power will be in the region of 350kW-400kW (469bhp-536bhp).” It also sez: "To achieve a 750kW short-term peak rating and a density of 59kW/kg … " Devi’ls in the details … The image on the ‘superblondie’ page shows A LOT of cooling built into whatever metal that is: https://supercarblondie.com/wp-content/uploads/YASA-tiny-electric-motor.webp

8·5 days agoIt was a decent summary, I was replying when you pulled it. Analog has its strengths (the first computers were analog, but electronics was much cruder 70 years ago) and it is def. a better fit for neural nets. Bound to happen.

5·5 days agoNice thorough commentary. The LiveScience article did a better job of describing it for people with no background in this stuff.
The original computers were analog. They were fast, but electronics was -so crude- at the time, it had to evolve a lot … and has in the last half-century.
The Moon never gets more than 5.14 degrees away from the path of the Sun (called the ecliptic).
In the northern hemispherre summer, your side of the Earth is tilted TOWARD the ecliptic during the day (23.4° at most), and AWAY from it at night.
In the northern hemispherre winter, it’s the other way around, because the Earth’s at the place in its orbit which is tilted (23.4° at most) AWAY from the Sun during the day. It can take a long time to get this all sorted out … If you’ve got a globe and light bulb, that helps …
but the Moon’s path is ALWAYS near that of the Sun.

2·19 days ago“reading” is not so common as it once was. what kind of reading are we talking about - fiction, non-fiction? Anyway, the numbers I’m seeing say that the US reads at a 10th-grade level, which is about average in the world. Of course it varies from place-to-place.

When it comes to non-fiction, today there are other ways of getting information. Youtube for one. Where learning from experts can often be better than reading a book. OTOH, you can lead a horse to water…
