For the last two weeks, a Sicilian Redditor named ItalianSausage2023 has been digitizing classic musical SNL performances from their own VHS collection. The audio and video quality's great, better than most copies of these recordings online—if they exist at all. https://www.reddit.com/user/ItalianSausage2023/submitted/

There are plenty in the running, but this is definitely in consideration for the worst contract signed in recent memory.

Every gun that is made, every warship launched, every rocket fired signifies in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. This is not a way of life at all in any true sense. Under the clouds of war, it is humanity hanging on a cross of iron.

If angles start with 0 at the top and go clockwise (which is how they work when defining bearing in navigation, e.g., or in a clock) you just have x=sin θ, y=cos θ, and take things from there.

I don't think that anything would end up being less "natural" or that you would necessarily end up with more minus signs in your formulas. But it would certainly be more confusing for us now that we all learned it the other way.

@johncarlosbaez
Any idea why the counter-clockwise convention for angles became standard in trig?

Here's a tale of how nature triumphs in the end.

Steel mills dumped molten slag in parts of Chicago and nearby areas. The slag hardened in layers up to 5 meters deep. These places became barren wastelands. Other industries dumped hot ash and cinders there.

But eventually the steel mills closed.

The deep layers of hard, toxic material were not friendly to plants. Cottonwoods are usually 30 meters tall or more. In the slag fields, stunted cottonwoods grow to just 2 meters.

But rare species that could handle these conditions began to thrive. The lakeside daisy, a federally threatened species lost to Illinois for decades, turned out to grow taller on slag than on topsoil! The capitate spike-rush, last recorded in Illinois in 1894 and considered locally extinct, was rediscovered growing on slag.

And more! Native prairie grasses like little bluestem. Native milkweeds. Even tiny white orchids called sphinx ladies' tresses.

A team of women ecologists began studying these unusual landscapes. They call themselves the Slag Queens.
