Humphry Davy Biography: a story of pre-Victorian drug parties, science superstars, giant stinky batteries, & chemistry "for the female sex". Check it out!
The modern picture of a bright arc lamp is taken with permission from an art installation called "Gravity of Light" by the very nice artists Doug and Mike Starn:

And, as usual, the music comes from the fabulous Kim Nalley.

Can I just say, your skill in crafting a lecture and your writing abilities are phenomenal. Then, to string them all together in a logical and compelling series is quite frankly mind boggling. This is a master class, one that people pay hundreds of dollars for. I feel like a little boy filled with the wonder of new and exciting discoveries. Thank you!

That is so cool! Do you know if anyone has a picture of your great, great, great Aunt? Inquiring minds want to know. (I think Davy is fascinating and got such a bad rep in the "Einstein's Big Idea" video, if you have seen that). My next video about Faraday's beginnings mentions him a lot too but from Faraday's point of view. I hope that it treats both men fairly.

The carbon arc system was widely used in such applications as big search lights, spotlights, movie projectors and in carbon arc welding and cutting. Davy left an impressive list of inventions including the explosion-proof safety lamp for miners.

Love all your lectures that combine history and science. Just a point, arc lamps were used well into the 20th century - I believe all the search lights in WW2 used them and also cinema projectors up until the 1960s (when they were replaced by xenon bulbs) as they produced a very pure white light.

Arc lamps were used by projectionists as recently as the early 80s. I remember our projectionists in Tacoma having to replace the carbons, and I remember the special generators in the basement they needed for the power. This was at the old Tacoma Rialto and Roxy (nowadays Pantages) theatres, which were showing popular movies.

@@Kathy_Loves_Physics Kathy, I had an idea that you may be interested in both for your channel and as a neat experiment. You may have seen a video of a guy who demonstrates gravitational forces in space by rolling steel balls onto a trampoline frame covered in a latex type cloth? That experiment is supposed to demonstrate the fabric of time/space and diagrams of Einstein’s theory take that form, more-or-less a large object in space curving a 2 dimensional grid. He had several million views so I guess it was quite a hit! The idea is to show this in 3 dimensions based on a Galileo thermometer type apparatus. As I understand it, that thermometer has floats in it that gravitate to a certain depth of fluid depending on the temperature of the fluid they are in. So perhaps if you take a large square sided glass bowl filled with this liquid and put a heat source in the center, like a tea element. Looking down on the bowl, the central part should be slightly warmer than the walls of the bowl. Perhaps rotate the liquid slowly. The Galileo floats should find a spot HORIZONTALLY comfortable for them between the walls of the bowl and the element (which is representing the mass full object in space). This should demonstrate that space time works more like a viscosity (3D) than warping (2D). Thank you! I hope my little comments on your videos have not spammed you I am watching my way through them and it helps me remember where I was. Have a nice day. Pete.

I believe that arc lamps were in general use far beyond 1900 as the concentrated tungsten filament didn’t debut until ~1913, I believe. I’m pretty sure they were used in searchlights through WWII and beyond. In some cases WELL beyond, seeing new, second lives for advertising purposes.

In addition to projection lamps, arc lights were the basis of the searchlights used in world war II to spot and target enemy airplanes over cities, and through my childhood to announce the location of circuses and traveling fairs. As recently as a dozen years ago I saw some being used by car dealers to light up the sky to lure people in for their Fabulous Sales!😂

I'm now curious about what the path from arc lights to arc welding might have been. Someone must have observed that unlike carbon tips, metal points and surfaces would easily melt under the arc, and material would flow opposite the direction of the current. Thus an entire industry and a revolution in material engineering arose.

I'm not exposing myself to that kind of psychological warfare that tries to force things into my mind by repeating them over and over.
