My favorite is "Brother Francis Gerard of Utah might never have discovered the blessed documents, had it not been for the pilgrim with girded loins who appeared during that young n…

Tom Murphy a "recovering astrophysicist" from UCSD, would beg to differ. His basic thesis is that, in order to build human settlements in other worlds, we would have to construct, …

I'm an academic. When I taught C++ last year, many students struggled because the IDE completed a lot of the code for them; their programming assignments scored high marks, but the…

I'm glad it's a push-button phone, and not a rotary phone. There's a hilarious YouTube of today's teenagers tasked with making a phone call on a rotary phone: https://www.youtube.c…

From what I’ve heard on “the history of English podcast”, after the Norman and invasion written English disappears completely for about a century. This is because the clergy and la…

This is a tax on wealth. Since many wealthy people don’t want to share their money, maybe it’s reasonable for some of it to be taken away from them and redistributed. That’s the re…

I bought some amber glasses from blublocker.com[1], because they link to a research paper that actually measured how much of each wavelength their filters allow (as well as other b…

Rumble is indeed a free for all, with lots of angry kooks. But it’s also a place where reasonable dissenting voices have found a way to get their ideas heard. It’s a mixed bag.

He criticizes the military-industrial complex. Don’t you think that’s an institution worth dismantling?

I don’t see where you’re coming from. Greenwald is constantly pointing out abuses of power and hypocrisy in government. Have you actually read what he writes? He is in no way a fan…

The backlash against the use of Ring cameras began with their tone-deaf superbowl ad. Amazon assumed that customers would buy their surveillance technology. The whole thing reminds…

Glenn Greenwald is back on substack. Yay! For the past few years, he’s mostly done videos on rumble, and he’s fun to watch, but personally I prefer his writing. In case you’ve been…

Air is mostly nitrogen. Nitrogen gas is blue. There.

As the poet Quevedo wrote, Nace en las Indias honrado, // donde el mundo le acompaña; // viene a morir en España // y es en Génova enterrado. (Mr. Money) is born in the Indies an h…

Ulichney (who wrote the book on halftoning) came up with ordered dithering matrices that give much nicer results than Bayer's, as good error as diffusion, and parallelizable. Look …

Why is there no mention of Don Quixote (1605) the first modern novel? It was divide into chapters, long before the Victorian era, which the author claims is when chapters in novels…

That’s kind of scary in itself. I’ll make a note to avoid drinking coffee from paper cups in the future! PFAs are everywhere in food packaging too. It’s disturbing.

I’ve heard RFK say that it’s hard to ban TV ads for drugs. They are “speech” according to the 1st amendment, or something like that. Too bad. News broadcasts are full of those ads,…

Yes, the measles vaccine is effective. It reduces cases of measles. But the paper in question says that deaths were reduced to almost zero before the vaccine was introduced. The gr…

I know I'm coming to the discussion late, but actually there is good evidence that improvements in nutrition, working conditions, and sanitation are a big factor in improving resis…

In the animations, New Zealand stood out: the high and low tide chase each other counterclockwise around the islands!

On the other hand, since cell cameras don't filter out infrared, you can use them to detect spy cameras in your airbnb, which are using IR to illuminate the room.

You're right. Coming up with a proof is a creative process. Each major proof in mathematics is so unique, that it usually gets named after its inventor. So we have Euclid's proof t…

Are you sure? The video I just saw on the BBC shows the tree being felled at its base! That's not pruning.
