LOL, that's faster than my 3x3 PB, and almost twice as fast as my 3x3 average...

That's insane. I can't even tell what method he's using. Does he just one-look every solve?

I'm not clear on how world records in FMC work. If the current WR is below God's number, are future WRs contigent on getting luckier and luckier scrambles?

Eh, I'll give windscreens a pass, since there isn't a great way to do them using multiple smaller pieces, but that dragon head sounds inexcusable. C'mon LEGO, this is not f*cking playmobil. Assembly is the whole point!

Hypothetical, but Black Hole Stars (one of my favourite Kurzgesagt videos).

"Normally that would be the end – today’s stars go supernova, a black hole forms and things calm down. But in this case, the star survives its own death."

"An impossibly dangerous balance has been created – millions of solar masses pushing in, the angry radiation of a force fed black hole pushing out."

I'm hoping that some of the new long wavelength teleescopes like JWST might have a chance of seeing one of these beasts.

Once it cools down, what sort of matter will remain? Would it have a solid surface one could walk around on?

We can't visit other star systems within our current lifetimes, but there's no reason we can't build bigger and better telescopes over the next few decades. That's the next best thing, and we can do it from the comfort of our home planet!

Your username is intriguing. Have you tried it? Is it any good?

Also, neutron stars are awesome. Densities on the order of "Mount Everests per teaspoon"? Almost unimaginable.

Anyone have any ideas on how to increase the particle size of the copper oxalate precipitate?

Here's the section most relevant to AVs:

Vehicle design trends are not all bad news. Since 2019, IIHS has been rating pedestrian crash avoidance systems, which warn the driver when a pedestrian is detected and apply the brakes if the driver doesn’t respond in time. We have found that this technology reduces pedestrian crash rates by 27%; even when it doesn’t prevent a crash, it can reduce the severity of the pedestrian’s injuries by lowering the impact speed. More and more vehicles are being sold with this technology standard, and NHTSA recently mandated it on new vehicles starting in 2029.

The efficacy of even simple collision avoidance systems just goes to show that humans are kind of terrible at driving. I don't think it will take that much for autonomous vehicles to be safer than humans on average. Computers don't get tired, drunk, or distracted.

Sounds cool. Could this be used to improve push notifications from Lemmy apps?

 

TL;DW: Some songbirds incorporate cigarette butts into their nests as pest control.

 

I must admit that the details of how the fields are coupled went over my head, but I found the rest of the video quite accessible. Professor Copeland is a joy to listen to, and Brady asks great questions as usual.

I also learned that "inflation" and "the big bang" are not synonymous, and inflation occurred first.

 

Not very practical, but the chemistry is interesting. Producing a strong acid from a weak acid by using precipitation as the driving force is something I don't see very often.

I assume that the bot is still broken, but Cortex continues.

It's time for Grey and Myke to talk about the devices they've chosen to use in their lives. From the computers they use to the offices where they use them, as well as the devices they choose for entertainment, travel, smart home, and fitness.
