Lord Kelvin's attempts to make mechanical models of elementary particles is one of the coolest failures in history. Also kinda tragic because he was so convinced that he could apply his engineering genius to the atomic scale that, late in life, he got a bit obsessed with trying to model the aether and refused to accept other theories. Shouldn't overshadow his many MANY other accomplishments though. Biographies of Thompson are always a good read, much recommend.

@@TheAgamemnon911 agree but there's a little more to it in this case. At that point in his life he hardly would have needed validation. Steve pointed out how lovely the idea was, even with the hindsight we're afforded today. I think Thompson was enamored with the idea of demonstrating a unified mechanics of the universe. He wasn't the first to aspire to that and he certainly wasn't the last.

The second time I was hallucinating against my will was much more enjoyable, but more painful. A couple years after that I was traveling from Central CA to northern AZ to look at a potential college. I took a flight down to LA, then a flight to Pheonix, followed by a 7000 foot elevation drive. During it all, as soon as we took off on the first flight, my ears wouldn't pop and the pressure in my head was getting excruciating. We got to the city that the college was in and I immediately went to the hospital. I had a double ear infection, sinus infection, and an upper respiratory infection. They gave me some really good meds and some steroids for my asthma. That night, while in the hotel bed, I hallucinated a full orchestra performing a double concerto with violin and clarinet soloists. It was so beautiful and clear and lasted about 15 minutes. I received a $40,000 per semester scholarship there for music and astronomy, basically a full ride, but all that pain and discomfort I experienced was probably the main reason I didn't end up going there

The observation that the figure eight looks sort of like a tetrahedron is a good one. The topologist Bill Thurston noticed that there's a way to glue together two tetrahedra with all the vertices collapsed to a single vertex, and then edges-to-edges and faces-to-faces, such that if you remove a small neighborhood of the vertex in the resulting topological space, what you get is a space related to the figure eight knot: it's the same topological space as the space consisting of everything *outside* a figure eight knot. (It's very mind-bending to try to perceive this...) He used this to show that the space outside of a figure eight knot can be given a hyperbolic geometry, and it was a key insight that eventually led him to his Geometrization Conjecture, one part of which was Perelman's resolution of the Poincaré Conjecture. Topologists still call it the "Geometrization Conjecture", but it's a theorem as of about ten years ago.

The tetrahedral symmetry is not too surprising if you know that the complement of the figure-8 knot is the gluing of two truncated tetrahedra. The edge colorings also match.
@columbus8myhw
@columbus8myhw Месяц назад
To explain somewhat, for those who are not familiar: take two tetrahedra, and cut off the corners (revealing several new faces, which I'll call truncation faces). If you allow yourself to deform these shapes like play-dough, and glue the non-truncation faces together in a certain way, the result will be essentially a doughnut with a knotted hole. If done correctly, that hole will be the figure-eight knot.

This is uncannily similar to my graduate thesis, except there we were exploring optimization algorithms and applying them to untying knots. In one part of the research we used prime knots as input for our knot modeling software and randomly cut the knots so that they would then be "untie-able". Then we used an optimization algorithm to "shake" the knot until it was untied. I'm not sure if the clips shown starting at <a href="#" class="seekto" data-time="298">4:58</a> are from something the authors provided or something else, but it looks so similar to what we built I gasped!

I thought of something you might be interested in looking into for your channel. When you aggressively pour a liquid into another liquid, sometimes some liquid will splash up into the air. I've been wondering if that liquid splashing up is the... "analyte" or the "titrant" (didn't know what else to call them lol, but you know what I mean). Is it always only the analyte or the titrant, or is it a mix of both? are the drops pure analyte/titrant, or are they x% of the analyte, and y% of the titrant? I dunno, just a shower thought that I thought you'd find interesting as well.

Would watching slo-mo videos of pouring coloured liquids help?

@@echognomecal6742 Yeah, that's what I thought too.

I doubt there's a single answer here. Say you're pouring A into B. If A is a solid (eg a marble) and B a liquid, any splash is all B. If A is a liquid and B a solid, it's all A. With both liquids, the situation is somewhere between these two extremes. Factors that will affect the ratio include the rate, height and angle at which A is poured, viscosity, density and surface tension.

Growing up my dad was a soccer coach and we had those foldable goals… I got like 15 sec in and started getting flashbacks of me almost in tears trying to get them to cooperate and go back in the bag 😭 lmao

I bought a tent that used this principle. I opened it at home after I bought it. I've never been camping in it.

Interesting! Reminds me of trying to remove a bandsaw blade from it's package and installing it on my saw. My bandsaw takes a blade that's over 18 feet long (about 6 meters)! It comes packaged in a flat box 'folded' into 7 circles. I've never been able to fold a dull one back up into 7 circles to make it manageable to re-box to throw it away.

Gym teacher here...we had these portable soccer goals that came in a bag. When pulled out they would pop up and be ready...problem was it would take up forever to figure out just how to get them back into the bag 😆
