I Don't Care What You Did Last Summer

What your teachers are doing

All of your public school teachers have a history. Almost all of them have masturbated. Many of them have smoked marijuana. Almost all of them have dated; most of them have danced. Some of them are gay. Some of them are heterosexual. Almost all of them have private kinks which you don’t know about, because they don’t practice them in public, let alone when they’re doing their jobs. Some of them have been sex workers.

And you know what? All of them can be fired or blacklisted by local prudes on school boards or the school administration. Teachers: you don’t get to be human. This outrages me.

Leaving CorVegas

desperately seeking sonya

Jen-Luc Piquant and I are heading out to Oregon State University today, as I am a featured speaker at OSU’s first Sonia Kovaleskaya Mathematics Day, honoring the prominent Russian female mathematician of the same name.

I am contractually obligated to link to activities involving Oregon State. So, here you go.

The Dangerously Clean Water Used To Make Your iPhone

The ordinary person thinks of reverse-osmosis as taking “everything” out of water. RO is the process you use to turn ocean water into crystalline drinking water. And in human terms, RO does take most everything out of the water.
But for semiconductors, RO water isn’t even close. Ultra-pure water requires 12 filtration steps beyond RO. (For those of a technical bent, the final filter in making UPW has pores that are 20 nanometers wide.

Water is a good cleaner because it is a good solvent–the so-called “universal solvent,” excellent at dissolving all kinds of things. UPW is particularly “hungry,” in solvent terms, because it starts so clean. That’s why it is so valuable for washing semiconductors.
It’s also why it’s not safe to drink. A single glass of UPW wouldn’t hurt you. But even that one glass of water would instantly start leeching valuable minerals back out of your body.
