Ahhhh.... I bought the entire collection of "The Amateur Scientist" a while ago in a CD ... there was some beautiful hard-core science experiments and tech back in the day in that column... now it's just ultra-safe, scientifically-correct kinder garden level boring stuff...

 

Destin is far cooler than I ever imagined:

The last few minutes of this video I think is relevant to our current political climate as well as the future of war against the world wide biological threats facing us now and in the future, a lesson can be learned here.

Edit: Basically viruses and the like are a bigger threat to humans than we are to each other.

 

He has achieved demigod status!

 

An excellet video showing a crossover between Smarter Every Day (Destin) and Veritasium:

 

Excellent demonstration on how carburetors work:

 

Way overly simplified. Shows full open but not any of the idle or transition circuits. At idle or transition no fuel comes through the main jet in the venturi. At those stages the throttle blade acts as the venturi.

 

My take away on this: the difference between engineering and art is how close one gets to failure without failing.

 

It took him a year, but Destin has finally released his third and last video showing how Kodak film is made. The series is now complete. Here's the first of three, really cool stuff:

 

 

That was pretty cool. Think of the odds it took for two civil war musket balls to meet head on. They opted to use the .45 Colt cartridge. The lead bullets for .45 Colt typically weigh in at about 250 grains with a safe velocity range between about 650 to 850 feet per second. Jacketed bullets can be pushed much harder (faster), well over 1,000 FPS. I load for that cartridge only owning a single revolver in the chambering. Really good video using the high speed camera.

I somehow missed this long ago.

Improvements I could make? A few but I like his design as it shows a deep understanding of the process.

Melted the slit while running hot.
This is a industrial size ion source and analyzing section. The ion source is behind the red bushing at up to 90kV potential to the motorized unit on the left that has electrostatic plates to move and center the extracted beam.
The vacuum turbo pump in the middle pumps out unwanted ions from the analyzing chamber.

I was designing an interface for the special pump to interface with the standard I/O module.


prototype turbo interface


final interface board design.

The sheer volume of gunfire needs to be incorporated when assessing the odds. It might well be that it was actually likely that some number of these would happen. If the odds of some outcome are a million to one and something happens a trillion times it is unlikely the outcome won’t happen.

This is all to say the number of shots fired in Civil War battles was astonishing. It was enough to cut down trees in wooded areas combatants were hiding in. While I don’t know if it is the case, I wouldn’t be surprised, considering both the volume and the intention to hit someone who is also trying to hit you, if it was likely that some even relatively large number of such events should be expected.

What does seem to defy the odds is finding an example. Because, even if it was almost certain that some number (let’s even say 100) paired bullets would result, finding a pair among the huge number of other bullets seems like a stroke of luck.

 

Very nice video on the subject of progressive stamp manufacturing:

What I've always wondered, if not somewhat suspected, was whether or not that civil war bullet-on-bullet wasn't a hoax to begin with.

It certainly could be. I don't know if anyone has done a thorough analysis of it. We probably have the technology at this point to do a really good job at vetting it.

I do wonder what a simulation would show about collisions, though. It is my intuition that such collisions would occur at least in single digits over the entire run of the war. The likelihood of finding such a pair seems to be inversely proportional to the likelihood of one being made, though.

 

Very nice video on the subject of progressive stamp manufacturing:

Watched that last night, and got very nostalgic. Lived that life for over 50 years. Would have been nice to see some plastic injection molding but he said it's going to be another video.

 

Should have mentioned that that shop was much cleaner and air conditioned, something not ever thought of anywhere I worked.

Amazing Talk. I loved that part about feedback.
