It's not that the math is that bad, understanding the implications of the math is the tricky part. But digital PCM upset a lot of folks when it was introduced.

Simple.

And "do you really want the theory"?

A copy of MathCad helps a lot in understanding these types of papers, as you have to graph the equations to begin to understand the real meaning of them. (Some like Mathmetica, I like MathCad, it's a choice.) As I've said before, you do better to just read the summary at the end, unless it really is of direct interest to you. Honestly, the derivative equations are simpler IMHO.

And I'll confess that it's been quite a while since I solved any partials, though I still remember them. If you don't use them, they'll slip away from you.

When that mess was first derived, there was a massive raid on the physics and math departments of universities and the national science labs. A debate on the social purpose/meaning of research vs making money was pretty hot at the time.

Interesting comment after the article. I had noted a few days ago that Das estimated that only about 2000 people in the world really understand derivates. Very similar comment here.

[quote]I worked for a very brief time on the sorts of radio technology now used in mobile phones. The mathematical analysis is ghastly. Turning that maths into functional hardware, pushed the limits of what we could do on the 70's, an yet by the 90's it was all understood, and there was a chip for it, and we could spit these things out in billions.
I dare say that not beyond a couple of thousand people in the world really understand how a mobile phone works, and not beyond 100 could actually design the chips that go in them. But that is enough.

Lampedusa has some serious problems with refugees, they've had more come in one day than the normal population of the island.

And an article/obituary on one of the last of the WWII generation.

Both are well worth a read.

The Arab uprisings have everyone confused.

Look at the Kurds, they've essentially seceded from Iraq and are running their "autonomous zone" as if it were an independant country. They are just as "uprisen" as the rest, they just managed it under US control and didn't have to fight Saddam on their own.

That's really a random sampling to show the kind of stories coming out of there. Just MHO, if the US military does actually leave Iraq, the Turks will invade the Kurdish area.

Some of that's just down the road from me. Literally.
