happy iron lung day to all who celebrate
A doll youtuber I watch has made a video about the history of Polly Pocket, and she's describing the plots of the dvd specials, one of which features an elderly woman named Ms. Throckmorton, and my reaction was
happy pride

A 50-kilogram anvil floats perfectly on the surface of mercury, because the density of the steel from which it is made is almost half the density of mercury.
damn that shit is light lmfao
Fun fact! Many lighthouses with especially large fresnel lenses would have huge fucking tubs of liquid mercury in the lantern room because it’s a super easy way to make these giant lenses rotate quickly!
Shockingly, however, spending most of your time in close proximity to 500 pounds of liquid mercury is Not Great For One’s Health and tons of lighthouse keepers started to go crazy from the whole. Mercury poisoning thing. Hence why there are a lot of “haunted” lighthouses or wickies that lose it and maybe do a bit of manslaughter.
Anyway, people saw a bunch of lighthouse keepers go crazy and get sick and got empirical evidence that it was in fact related to the 500 pound mercury bath they have to visit every day and then they decided nah it’s fine actually. So we’ve kept the liquid mercury thing and I think that’s beautiful
I love how it is so dense it does not "wet" the anvil, the drops all run and leave with nothing behind them unlike water, oil, sauce... it's super satisfying it's like in cartoons
In a letter written on April 19, 1825, Augustin Fresnel proposed the use of mercury to reduce the friction in revolving lenses. His statement follows: “I propose to float our rotating devices, of the first order, in a bath of mercury, instead of placing them on rollers. This project won't present many difficulties; nevertheless, as I have not put it into execution, I won't require you to adopt it for your first lighthouse.”
Fresnel’s plan for mercury flotation was not put into practice until 1890 when Monsieur Leon Bourdelles, Chief Engineer of the French Lighthouse Service, designed and built a workable mercury flotation system. The mercury bath allowed the lens to operate in an almost frictionless environment and, additionally, allowed the speed of rotation to be dramatically increased.
Lens Rotation by Thomas Tag | United States Lighthouse Society
Ah to be a sailor in 1890 who has to turn to his fellow men and ask "is it just me or are the lighthouses flashing faster?"
They had been slowly getting faster for decades.
It mattered for optics reasons.
Under less-than-ideal conditions, you can only see the beam when it’s pointed more or less directly at you. In-between beams you would not be able to see anything. One solution to this was to create multiple beams, and the lenses Mr Fresnel designed usually created 8 beams. But, even still, duration between flashes could be as long as one minute in the old mechanical roller systems.
The nearly frictionless operation of the Mercury suspension system allowed the lenses (large pieces of precisely ground glass weighing several hundred pounds in some cases) to rotate fast enough that they could be redesigned to create fewer (usually 3) beams. Fewer beams from a similar light source will be proportionally brighter, and the gains in speed were sufficient that duration between flashes could still be reduced to as little as 10 seconds.
This was a big upgrade. It didn’t just make the lighthouse signal faster, it allowed them to completely overhaul the lens and derive more visibility from a light source.
What’s a little Madness, in the face of Progress?
mods are asleep, post the fresnel lens
my devoted but dangerously unstable knight will be hearing about this
Well, at least she died doing what she loved—getting her dick sucked.
Anon hate is shitty and you shouldn’t do it of course but it’s also the funniest and least effective kind of hate
For starters the blogger can just delete and ignore it. And given tumblr’s penchant for eating asks I think it would drive some hate senders a little insane if they keep checking back in wondering if their ask got eaten.
For second the anon ask format guarantees the blogger gets the last word in every time. Even if anon sends a follow up message they will never get the last word. And tumblr for better or for worse seems to run on this currency of “whoever expressed the last opinion in a post is the one we’re supporting”
For third, this publishes the hate directly to the blogger’s own followers, i.e. the people MOST likely to take the blogger’s side. Home court advantage by design.
#I call for an audience with the king. After waiting in line I stand in front of his throne #(dressed in a huge white bedsheet like a cartoon ghost so as to hide my identity) #I call the king a bitch. I insult his policies all of which were made with the guidance of his court who r also all here #the king ignores me. I say it again in case he didn't hear. The king ignores me #I leave in shame (via @septimus-heap)
The funniest part of anon hate is, if the person opts to block you, it'll be an IP block. So even if you decide to log into another account, you'll still be unable to send them any more asks.
earlier I was coming back up from skating and one of the starstruck little kids from across the hall asked me, “how are you allowed to drive on the inside?” (referring to the fact that I carefully skate in the hallway and elevator, because swapping shoes on and off for the one-block commute to and from the park is a massive pain in the ass), and I swear to god the dialogue options that flashed up on my heads-up display were
[] Nothing in the lease explicitly says I can’t, and all uncodified rules are merely suggestions
[] I’m probably not, but the only people in this building who are fast enough to actually stop me are the maintenance guys who are all charmed by my kind green eyes and adorable dog
[x] I ate all my vegetables and did my homework so my mom said I’m allowed to do whatever I want

you don’t realize how important lunch is until you’re wandering around thinking about how unloveable and untalented and uniquely cursed you are and then it’s 4pm and you finally eat lunch and you go Oh. oh right.
lot of people commenting on this post like "who eats lunch at 4pm that's a terrible time to eat lunch" yes. that is the point. 4pm lunch is inadvisable. 4pm lunch is not the ideal. 4pm lunch makes the mind demons real.
being a kid and hearing adults say stuff like "woah 2011 was 4 years ago haha" didn't really convey the fucking horror of a youtube video crossing my recommended labelled "9 years ago" and it's from 2017. that's not true. 9 years ago is 2010 or something. don't lie.
the mythbusters once tested "herding cats" and at one point they brought in a proper trained herding dog and the poor dogs face when the first cat responds to his herding with swipes and aggression is to look at her human and go 😰 the sheep is broken?? what do i do boss??
what’s the rush?
The time will pass anyway
