A bit of a mix of electrical, electronic, mechanical, 3d printing, machining and kinematics. This is the latest of a long series, episode #15. James does all sorts of projects, but this project is the most sciencey one IMO.
"Aluminium has a relatively low melting point (660°C) but its boiling point (2470°C) is very high. The parabolic shape (funicular curvedes) which the wire takes on when it is heated ensures that the oxide shell does not break.
When reducing the current, the wire always breaks."

Solving EQUATIONS by shooting TURTLES with LASERS
Thanks for sharing that video, this Mathologer guy is now one of my favourite channels to watch! Pretty cool stuff and he's funny for a mathematician! I just watched one where he talked about squaring triangles and how to prove certain square roots are irrational! Mind blown!
I'd have to place 3blue1brown higher, but it's hardly a competition, they're both well worth watching.
Yeah, 3blue1brown is also quite good, very nice animations... ... if Mathologer is Batman then 3b1b is Robin.

The
Bulwer-Lytton Fiction Contest challenges writers to write a really bad opening sentence for a novel.
2005 winner:
As he stared at her ample bosom, he daydreamed of the dual Stromberg carburetors in his vintage Triumph Spitfire, highly functional yet pleasingly formed, perched prominently on top of the intake manifold, aching for experienced hands, the small knurled caps of the oil dampeners begging to be inspected and adjusted as described in chapter seven of the shop manual. — Dan McKay
2007 winner:
Gerald began – but was interrupted by a piercing whistle which cost him ten percent of his hearing permanently, as it did everyone else in a ten-mile radius of the eruption, not that it mattered much because for them “permanently” meant the next ten minutes or so until buried by searing lava or suffocated by choking ash – to pee. — Jim Gleeson, Madison, WI
Fun website where guy trained an AI to understand the relationship between 2000 images of cats and their line art equivalents.
You can draw a cat diagram and have the AI turn it into a real cat photo, or at-least try too 
https://affinelayer.com/pixsrv/
Note: On some computers the website doesn't work. I think it uses some CPU extensions not found in older processors, or maybe it uses CUDA for all the AI processing.
Go ahead and try to sketch you own cat. Be creative, even unconventional.
See?
