so done with tumblr. see u all in two minutes

"this is what ive BEEN saying" - me about a thought that 99% only exists in my brain and i maybe mentioned briefly in one tag once

[juu-arts]

What if Geodude had legs

ok nvm

life hack alert! finding ants on your scone = a free meal so always keep ants in your pocket when eating out (just incase your food doesn’t come with ants)

[oodlyenough]

when i blacklist something because i don't care about it i never feel compelled to open the posts and they just wash over me like white noise. when i blacklist something because i actively dislike it i end up opening that damn post like 85% of the time just to go yep. hated that.

[longseasons]

does anyone like me and want to understand me

[berrycobbler]

if you're a ceaseless watcher it must feel good as fuck to turn your gaze upon a wretched thing

I can smell the poison in my goblet but I lowkey don't even care anymore

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

[ben-the-hyena]

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.

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?"

[asteroidtroglodyte]

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?

HOLY SHIT GUYS, I WAS INSPIRED BY THIS POST TO TRY MAKE THE SONG AND YOU WOULD NOT BELIEVE THE SCREAM I SCRUMPT WHEN I DRAGGED THE TRAINING AUDIO OVER THE BACKING TRACK AND IT LINED UP PERFECTLY

Tempted to actually put this on spotify so I can secretly stream it at work...

Tagging @batshit-auspol because as an Australian you're the only big account I know who might share (sorry).

happy first day of pride everyone

I wish there was a way to completely OPT OUT of GEN AI. Like you could set your ENTIRE Internet browser to NOT shove it down your throat.

When social media was getting big, you could just NOT get a Facebook or a Twitter. It was simple as that. You can't do that with GEN AI.

Trying to find a job? It goes straight to an AI filter. Trying to look at art? Here's 100+ ai shit. Trying to look up who was in what movie from the 1980s? GOOGLE GEMINI IS HERE WITH THE COMPLETELY WRONG ANSWER!

Someone PLEASE create a way to allow people to get GEN AI the FUCK OUT of our lives if we DO NOT WANT IT!
