It is garbage because a very closed CPU is used as an educational platform without datasheet availability.

This Broadcom SOC is great for mass-produced routers, bad for sharing with people trying to learn how Linux boots, learning assembly and possibly advancing to their own RTOS. I'm aware of the measly peripheral datasheet sections that are available online, but for Atmel and NXP chips one has to read a LOT more to make basic hardware level programs (how are the VICs nested, timing and boot issues/settings, other exceptions made by Broadcom i their ARM11 implementation etc).

Consistency is unimportant if youre giving people a board with the OS pre-installed, the kernel can handle different CPUs while users use different programs. But if you want to learn a bit more and go lower level (for example from Arduino), you're screwed by Broadcom SOC's severe lack of documentation. And forget about learning to code for the GPU.

I was thinking the same thing. AIM was the first feeling of being online? Hell no! It was 9600 baud modems, BBSes and the first live chat for a lot of us was IRC.

I know I know unix has a chat thingy too, but it was IRC that connected the world, in strange little dungeon chatrooms, where you had to smell the bots before trying to download mp3s from them :)

When the first-ever reactor was being setup by Fermi, he know exactly how to build it and what the results will be. No human had ever built one before. And yet it was 'science' before the first reactor.

More than being 'testable', science gives you results rather than emotional satisfaction. There is much of science not testable (immediately) such as time travel and the likelihood of intelligent aliens in nearby galaxies.

A different definition might be:

- Science is the most likely truth given the observable

- Religion is usually the least likely truth, but one that emotionally appeals to us.

It was religion that claimed the world is flat, and sits on the back of a giant tortoise and a few other animals piled up. Science claimed the world was round before it was directly testable. It because testable when people sailed around the world. Yet there are still people in the 21st century who believe the world is flat, and they're being lied to.

Holy assumptions in the original article. It links the core's relative rotation to the magnetic field. The magnetic field exists because a huge mass of ferroelectric material rotates.

Now which do you think affects the magnetic field more, the cores RELATIVE rotation speed (a few degrees in a million years?) or the overall Earth rotation (roughly 365 degrees in a day)? This is like putting a magnet in a plastic cup, rotating the magnet, and rotating the cup SLIGHTLY slower, and saying the resulting magnetic field is due to the cup rotating SLOWER.
