If you go 80 mph on the way there, and immediately turn around and go 60 mph on the way back, what is your average speed for the 160 mile trip?

Tap for spoiler68.6 mph

I believe the most computer proficient people were born between 1975 and 1995. Before that and they were too old to figure it out without a lot of effort. After that they grew up with touch screens and it’s all just magic. Right in the middle we were able to grow along with advancements in computing.

I was teaching a class with mostly students born after 2000. One of them had never used a computer with a keyboard and mouse. Never used folders and files. Kind of blew me away.

This covers the “curious” part. But as Musk said it must be both curious and truth-seeking. You won’t get super intelligence from curiosity and creativity, you’d get an art major. Intelligence needs to be discerning and yearning for truth and understanding.

I used to get it fairly often. I would almost always get it when I slept at my mom’s house. For a while I thought it was haunted but then I realized it’s just associated with sleeping on my back. But oddly enough I had a really creepy old hag one particular night who was sticking her tongue in my ear. I strangled her and I haven’t had sleep paralysis since.

Thank you. This is really huge news and will probably be reposted a bunch with proper non-clickbait titles.

Unfortunately it doesn’t really incentivize smaller or lighter vehicles in any way.

The average mileage for light trucks, including pickup trucks and sport utility vehicles, would have to reach 45 miles per gallon, up from 35.1 miles per gallon.

That’s a reduction from 2.85 gal per 100 miles down to 2.22 or a 22% reduction in fuel consumption.

The standards will also require heavy-duty pickup trucks, such as the Chevrolet Silverado 2500 HD, and large vans, such as Amazon delivery vans, to reach 35 miles per gallon by 2035, up from 18.8 miles per gallon today.

That’s a change of about 5.3 gal per 100 mi to 2.9 gal, or a 45% reduction in fuel consumption.

A Toyota Highlander Hybrid currently gets 35 mpg. To do over 20% less fuel it would need to be super aerodynamic, and lose about a ton of mass. Or it would have to be fully electric - the Rivian R1S gets 70 mpg equivalent.

Yeah a tiny bit.

I agree, but I did have visuals as well.

It’s easy to restrict access. It’s hard to restrict access while letting search engines index your content, driving traffic. Maybe a local paper simply gets most of its traffic from the first paragraph summary, or local subscribers, so they don’t need to let Google index the whole article.

It’s explained pretty well in Optical Physics for Babies. Take a peek in the kids books section next time you’re at a book store. It also explains double rainbows, and why the second one has the colors in reverse order and is always more faint. This is a detail they got wrong in my favorite episode of Bluey: Rain.

Well at least all the international visitors wouldn’t be disappointed with the dry cliffs.
