Bessel Functions Gonna Function, Yo! That's the way we roll at the subterranean dungeon that is my basement #Maharchives.

Having popped out of the womb and spent 22 years in the classroom does not make you smart, clever, or even knowledgeable. It makes you educated - which is an entirely different thing. We have created an intellectual tower of babel where, without generalists, consequences are not perceived.

What's great about the baobab thing is that the initial papers make no mention of sterilization procedures for the core drills. No mention of research proving such bore holes could be survived by the trees. It's worse than that idiot who cut down one of the oldest bristle cone pines.

Then we had climate researchers claiming Ozone Holes gave frogs sunburn, causing a dieoff. OR.... the researchers studying the frogs carried a deadly skin fungus to remote frog populations they studied, thereby killing them.

Let's make a movie about that. We need a movie about scientism.

Climate change researchers were taking dendrochronolical bore samples from thousand year old baobab trees, on coming back, half were dead. They liquefied and rotted from the inside. Conclusion: climate change. OR... COULD DRILLING A 10 FOOT DEEP HOLE INTO THE TREE CONTAMINATE IT? GEE, IDK!

The "OMG, some people with money whose name is on a 100 year old ceramic are not supporting my political bull-bleepery!" is hard to stomach.

It's going to be a ripple tank, God willing.

They also often start with scientists and engineers designing something so insanely dangerous that only their hubris, corporate profiteering, and American exceptonallism spurs on the project to initial success - then ultimate disaster.

IIRC about half the activity of natural uranium is from ²³⁵U and based on your video that "sounds" about right.

There is some clear emission from the depleted Uranium. :)

Here’s a ~1g example of depleted uranium followed by isotopically natural material.

The depleted stuff sees a lot of use for shielding still, it is minimally active with a favorable density for the application.

Damn! Where an I supposed to get depleted uranium now? Depleted Uranium Depot? Depleted Я U-238? Because those went out of business during the financial collapse of 2008.

It looks like a herd of wildebeest overwintered in my back yard. I refuse to poison it, so it turns purple from the violets, and yellow from the dandelions, and red from windswept Coke Zero cans.
