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!

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.

From the #Maharchives: IDK, something wierd I've wanted to make for a while. I TRIED super glue, but that failed. So to recoup after several failures, I used urethane foam - which was the perfect solution, but applied poorly. "The next time, it will be flawless!"

I just got back from a 4 day, 300 mile outing in my VW Bus. It was a super fun weekend exploring junkyards and visiting friends.

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

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

Hereโ€™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 ะฏ U-238? Because those went out of business during the financial collapse of 2008.

I saw this on the side of the road while biking, stopped, and picked it up. 60 second later I wrecked.

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.

Prohibition started in Colorado in 1916. The Coors family pivoted to ceramics, using the rich clay deposits around Golden. That kept the family business afloat until the end of Prohibition in 1933. Coors Porcelain Company became CoorsTEK, which is still in Golden today.
