    For a quick and dirty clean room run the shower really hot for a few minutes to make a bunch of steam and then wait for the humidity to naturally equalize, boom you got a few minutes to do your swap job.

    I’ve never heard of this… what’s the idea behind it? That you get the RH near 100%, and any dust particles will be a nucleation point for water to condense on, causing them to literally rain out of the air?















  • This is kind of a weirdly phrased question.

    Mathematically, THE argument of the sine function is the angle in question. One definition of sine, using the sides of a right triangle, is the ratio of the opposite leg to the hypotenuse of said triangle: sin(theta)=opposite/hypotenuse.

    Edit: it occurred to me that maybe what you’re asking is how to compute the angle, theta, for which sin(theta) = a certain ratio of opposite/hypotenuse. There is an inverse sine function (often called arcsin) that does just that. Arcsin(opp/hyp)=theta. That’s the case where it would make sense to take the side lengths as arguments.

    Going off OP’s thought–the pump or spray bottles whose design and/or straw length makes it literally impossible to get the last bit of product out. I’ve had some where the straw just plain ends about 1/2" from the bottom so there was never even a chance to use all the product you paid for.

    The worst part is I’ve also used spray bottles that–through very minor design tweaks–enable you to get virtually every speck of liquid. So it’s not like it’s even hard problem to solve, but fuck you just throw out the last 10% and buy a new bottle!
