and the universe said i love you.

too many people completely separate disability from themselves in their mind. it's something that happens to other people. other sad people i don't want to think about. are they really even people, it's too much to bear thinking about that happening to a person... those background characters over there. it would never be me, i can't cope with thinking about that possibility.

this mass denialism of the fragility of the human body (YOUR human body) has created a whole category separate from the disabled - the "elderly." since anyone can join it if they live long enough.. no they can't be disabled. that's scary, and worse it's political. so they are just "old." so what they lost their hearing, their mobility, their heart function? that's just how it goes for old people. as if that's not a person as real as you. as if you wouldn't be devastated if that happened to you today (and it can btw). as if you won't be when it's your turn to be old, and disabled.

My grandparents lived to 98 and 103. Read that again— 98 and 103. My grandmother died 5 months ago and was born in 1923.

She was extremely wealthy. My grandfather left her millions. She paid about 13,000 a month for her care.

And her nurses abused her. She could do nothing. She could not speak for herself, feed herself, clothe herself, and the humiliation they made her endure was disgusting. When she tried to express discomfort, they gave her drugs to “keep her calm” (keep their shift easy). We fought like HELL to hold that fucking place accountable. The only reason we were aware is because we hired a private nurse on her behalf, too.

The elderly are a massive, extremely vulnerable, and disabled group. You cannot leave them out of your advocacy, you cannot leave them out of the conversation. “They’re loud, they smell, they’re opinionated, they’re rude, they make me uncomfortable”. I don’t care. I don’t care! They need your advocacy too! I want you to think, if my grandmother— who was in the best retirement home she could afford, with a personally hired third-party nurse to step in where the other carers failed, had such abhorrent care… what about everyone else? What about all the elderly who don’t have a support system?

when i was a kid, i would have to tiptoe around his anger issues often, sometimes running quietly past his work table until he got his own place completely separate from our family, locked away for days. every so often he would start screaming in the car and trying to hit me or my brother for talking too loud while my mom attempted to calm him down as he swerved on the road. and now he, smiling, helps me with car insurance.

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.
