It might be the damn phone.

At the 1985 Labour party meet, the motion to support LGBT rights as a party was passed due to a block vote from mining unions.

thing thats bad: aww

thing that has both genuinely amazing pieces of storytelling and abysmal dogshit slop both happening like entirely interchangably:

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.

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.

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.

my friend's 5 year old recently got a toy veterinary medicine set - it's super cool, like one of those mini play kitchens a lot of kids have, but it's set up to pretend to be a vet (it's this thing) - it has stuffed animals and things to weigh them, give them medicine, take x-rays, write on their charts, etc.

so this kid, who is five and to my knowledge has no experience in the administrative bureaucracy of modern healthcare, puts a stuffed pig named Piggy on the exam table. she pretends to draw blood from Piggy using a fake syringe, and the blood goes into a toy test tube vial that she calls "the resulter"

i'm playing with her, right, so i'm like, awesome, what are the results of Piggy's blood test? and she says "we have to send it to the scientists." so we send the vial to the scientists (put it in her bedroom) and when we get back to the vet playset i'm like awesome what did the scientists say? and she says they have not gotten back to us yet

so she rolls her eyes, exasperated, and says we have to call the scientists. she pretends to call them. apparently, they tell her that Piggy's blood test is "at the bottom of the list" and "we have to WAIT." she frowns. we wait a bit longer and call them back. they tell us it will be a while! she says we should go ask the scientists in person so we go back to her bedroom and she inquires at this imaginary lab, at which point the scientists yell at her and tell her now they will make us wait even longer!

keep in mind she is 100% directing this play. she is making all this up. she is fully in control of this game, and she has decided that what we are going to pretend is that we are dealing with this exhausting nonsense, not actually treating Piggy.

finally the blood tests come back. they are inconclusive. the scientists do not know what is wrong with Piggy. the little girl walks back to the stuffed pig on the exam table, sighs deeply, and says in a very serious voice "we can never help you."

i'm obsessed with this kid. when given complete control over a make believe scenario, instead of becoming the heroic rescuer administering effective cures, she is instead a beleaguered vet making multiple calls to an overworked lab only to be left unable to help her patient.
