Roger Dean creates wonderful science fiction scenery.

Recently read Against the Fall of Night by Arthur C Clarke, which is bursting with interesting ideas. Some more for thought:

Outer Space – I bet you can figure out with decent certainty your location across the entire universe just from sampling the nearest bit of space.

Heliosphere – Similar to the above; every drop of space from many AUs away to the nearest lake has a unique composition.

Deep Space Network – at the very least a catchy name

Voyager 1’s Family Portrait

New Horizons – Almost to Pluto!

Thermoelectric Effect – not directly related, but super cool

What is a Fourier Transform?

, , on October 27, 2011

A mathematical method of converting a set of data (represented as any function) to the sum of its wave components.

Basically, this is a result of the idea that a function can be exactly recreated using only combinations of sin and cosin functions of various amplitude, phase, and frequency. The trick is that most transforms require a lot of computing to tease out every wave component.


Maxwell’s demon and the Nasal Cycle

Maxwell’s demon and the Nasal Cycle, both things you should know, of course. Don’t mind the damn Jimbo!

Update: Oh, so there is some testing and rationale behind the Jimbo appeal.


White Hole

Terrific model and easy visualization. The circular jump is a white hole (G. Jannes, R. Piquet, P. Maissa, C. Mathis, G. Rousseaux).
