Well for example take the least squares formula \theta = (X^T X)^{-1} X y. You derive that by setting a derivative to zero, and solving for \theta. If you don't know what a derivative is, then you're just using an equation that came out of

He must have been already recognized as being very talented in mathematics to get accepted into the Ph.D. program at Princeton. They only accept around 15 students every year from all over the world. I wonder how did his talent demonstrate

Maybe I didn't understand something, but it seems to me that companies like Blippy would have to change something in their code to link with your server instead of Gmail. If it's the case, it would be hard to get everyone to adopt this syst

It was probably just called the 'anechoic chamber', which is the correct technical term.

I have been on a tour of a chamber like that recently, and the blue material in the spikes has roughly the rigidity of cardboard. The material is reinforced by metal wires, however. Even though the wires are not very thick (you could bend t

However one very useful thing this tablet can do that the iPad cannot is serve as a notebook (because it has a resistive and not a capacitive screen). I'm a student and I would love to have a cheap portable device for taking electronic note

Since Steve Jobs is known for replying to emails, people can potentially try to manipulate Apple's image like that guy did. It could hurt the reputation of the company; I wonder why Jobs does that (and his emails usually don't have much con

The Poincare-Perelman theorem. That's how it's probably going to be called.

That joke is from the Time magazine article, where they name Putin man of the year.

You're contradicting yourself. If you don't believe in objective reality, you can't use biological arguments involving the brain. If you doubt objective reality, then you have to doubt all those observations about the brain you mention. (Na

I'd bet that the quality of the display is already much worse on the MB.

It's a shame that he doesn't paint something more compelling than ketchup. Photographers can create truly astonishing work based only on what they get through a lens. With his technique he could produce even more impressive and thought-prov

I think he was trying to say that the magnitude of the mental boost from using amphetamines will not compensate for the health risks, and that if your mental skills are not already extremely sharp without amphetamines (like those of Erdos),

It seems to me that a great interface for presenting products would almost necessarily have to be individually designed for each store. I don't see how you could use the same kind of interface to present, say, books and perfume. Also, I hav

All Of Statistics by Larry Wasserman. The material is presented both very succinctly and rigorously, and overall it's the best statistics book I have come across.

What bothers me the most when I read this kind of stuff, is that there is no clear reason why the success of Feynman & co. should be attributed to some innate talent rather than to hard work, and yet most people firmly believe in the fo

Why don't you publish your magazine online? There's alltop.com that does something like this already, but I can see ways to make it better.
