Oh man, I read a super cool article about that about a year ago. It provided an algorithm for automatic differentiation using an imaginary number such that it times itself equaled 0, but wasn't equal to zero itself. I'll try to fi

There are models using higher-dimenions (and lower dimensions, and factional dimensions) to model physical phenomena, but the problem with a lot of them is that you end up with the "fitting n points to an n degree polynomial" prob

Yeah, they can do deterministic calculations. You just avoid ever putting the quibits in a state where measurement gives probabilistic results. it would, however, be a ridiculous use of technology, like using a Neural net to simulate an XOR

Our professor loves to tell the story of how one of his friends in grad school based his thesis on a series of experiments to be run by a mars probe. One morning my professor runs into him and he's just completely panicked. My professo

Wait, that's not the norm? What's the alternative, do they just let a professor invent a couple dozen projects?

Don't you dare talk shit about my Unicode characters. Any langauge written after Unicode's adoption has no excuse not to use them. They're wonderful. They're magical. They let you say exactly what you mean, and keep it c

Yeah, the problem is that diseases have effectively 2 different fatality rates: one for those who get medical attention, and one for those who don't. As a medical system approaches saturation, it becomes harder to get medical attention

I'd call lawn darts safer, as the danger with them is a lot more obvious. Everyone understands that throwing sharp things at people will lead to injury. It takes a significantly more informed consumer to know that a product masqueradin

Arm bands should never be used. Unless they're the kind that has a chest piece, there is a significant risk of them pinning a child's face in the water.

As a lifeguard, I'm going to have to disagree with you. Arm-floats are blatantly dangerous, and should never be used. If they don't fit exactly the way the manufacturer planned, they run the risk of pinning a kid's face in th

Almost certainly. Of the saves I made over the years, the only one where I wasn't already giving the victim extra attention for 5-10 minutes was a seizure.
