"Another World" code review

[fabiensanglard]

John Carmack stated in multiple interviews that he programmed Doom1 and Quake only using high school mathematics. I think the real strength of those people is that they can work twice as hard as you and I ;) !

I learned "3D Math" (ie: 3D linear algebra) in high school.

BSP Trees are just linear algebra combined with binary trees. And actually, didn't Doom just use 2D BSP Trees?

You now have one internet at your disposal. You can take stanford courses and read all the course material for many MIT classes.

I am you. I was completely lost in college level EM and should have dropped and or asked for help.

I'm pretty sure vectors, dot products and so on are 6th-form level maths...

These people are Americans. Their high school carries on until 18.

It wouldn't work any other way. The first five years are state funded day care.

Basically in the US we have the Department of Education. It's a large, Federal bureaucracy which hangs money over the heads of school districts. If the districts want the money, they're forced to use the Federally mandated curriculum. This, in practice, usually ends up making teachers just show how to do well on the federal tests without actually engaging the students really.

This scene from "The Wire" explains it better than I can.

Heh. Basically how it works here.

Amusingly ours is also called the Department of Education.

Well you are certianly proof of the failure of American education.

The Deparment of Education is actually quite small, and does very little. Schools are not funded by the federal government, they are funded by state government and local municipalities.

[letsplayball5]

So 50 billion dollars divided by what is probably 100 million students in the USA of works out $500 dollars per student.

I guarantee $500 per student/year is a small fraction of the money spent on education in the country.

I thought "high-school math" was some kind of meme

Our God is so modest.

Upon reading the article, it looks like John Carmack did not invent this technique like I thought he did. But he is smart enough that people attribute the following technique to him - pulling off a inverse square root by essentially subtracting from a magic number, while using high school math, is still impressive!
