Pff. You call that flying?

Oh like you can hit reverse.esrever tih nac uoy ekil hO

I remember it was in the new books section of the school library and I was attracted to it immediately and spent the day reading it instead of paying attention in my classes. I need to read it again. Thanks for bringing it up!

I read that ages ago. Back in high school, in fact (I’m 46). I don’t remember it except the chapter where time is a flock of birds that you have to try to catch to stay youthful. The children can catch them but always let them go and the adults can never catch them.

Wow.

Mercury arc valves remain in use in some South African mines and Kenya (at Mombasa Polytechnic - Electrical & Electronic department).

Amazing how we’re still using such old technology in some places when we have semiconductors.

That said, a microscope that generates its own light without electricity could be quite useful…

Wheeled carts are not very practical without draught animals to pull them. And the one place they had animals like that, in South America, llamas and the civilizations that utilized them lived in the mountains where wheeled carts aren’t practical either.

They say that Native Americans never developed the wheel. They clearly did. For sick dog skateboard tricks.

Tomatoes can be grown pretty successfully indoors. Also prickly pear.

There’s an article about it in the New York Times which apparently goes into much more detail, but I don’t have a subscription- https://www.nytimes.com/2023/07/10/science/silence-sound-hear.html

It is excerpted in this Slashdot post, however, and that may give you enough information to understand it better: https://science.slashdot.org/story/23/07/10/2343221/silence-is-a-sound-you-hear-study-suggests

To sum up, it’s not about total silence, it’s about perceiving gaps in louder sounds as “sound” rather than the lack of sound.

Or is it… EeeeeeEEEEEEEEEeeeEEEEEEeeEEEEeeeeeEEEEEEEEE

I remember how in The Matrix movies, humans blocked out the sun to stop the computers from taking over. Looks like we’re going to ask them whether or not that’s a good plan first in our timeline.

Not the science we asked for, but the science we need.

Probably. I was a power user there. No more though. Sorry, I wish I remembered you.

We had a grapefruit tree in one backyard and a key lime tree in another in the places where we lived. Never got an orange tree sadly, but there were lots of opportunities to get fresh oranges. Avocados too.

Alternately, they leave them there until they die and replant them. That just occurred to me and it’s the sort of wasteful thing the entertainment industry does.

Hollywood. Raleigh studios. They had them all along the outside.

Great. Capitalism literally makes you stupid.

Beautiful. My mother always grew them and, growing up in Indiana, they were grown indoors (they’re not fans of cold). Then I moved to L.A. and my first day on the job, I see a row of African Violets planted outside the building. I was just stunned.
