In about 250 BC, the Greek mathematician Archimedes figured out that you could inscribe and circumscribe polygons on a circle, calculate the length of the polygon, and get an upper and lower bound of pi. He was accurate to 1/1000.

This is just a scaled up version of what fish do to insects all the time and the likes of flies are very quick. It is a little unusual to see it, but it's not really that spectacular.

I was preparing a presentation where I mentioned that the Atlas rocket had a "1.5 stage" configuration. I opted to illustrate it with a painting because in a photograph the exhaust is so bright you cannot see clearly the three engines

You had furniture in your school? We had to make do with moldy cardboard boxes for desks and sharp piles of rusting scrap metal for chairs, and we had to collect the scrap metal ourselves from train yards and storm drains.

We had to use cleverly arranged FedEx boxes Sure, we sold out, but we all got free mouse pads!

I don't believe people get the shakes from fat withdrawal. (By the way, this photo came from fatty, well-marbled beef.)

If it turns out to be real, I want Martian snow as my screen saver.

There's plenty of snow on Mars. Here's a nice picture.

I agree with Dvorak. Maybe that's because I'm somewhat of a dinosaur too. So I wrote my own photo program that performs the important fundamentals, such as merging Mars Rover raw photos into color images and generating web pages with lat-lon-altitude from the image exif info. Important, fundamental stuff! (This can't be advertising if if I don't make any money on it, right?)

For a big group of color images and an explination of why they look the way they do, check out http://www.xpda.com/mars/

I have found that a good place to view pictures, particularly for us normal people is at http://xpda.com/mars/. The guy there has put together a really nice page with Pictures from the rovers... he even used multiple images with the different spectral filters to show us color photos. -Although it may not be the perfect site for scientific research, it's realy nice for us normal people to get a feel of what it looks like on Mars, and what the rovers have been upto.

For those who are interested he also has a real nice writeup about how he makes the color pictures and what the different filters the cameras use and why.

And another mirror, for your enjoyment...

sort of offtopic, but...

Has anyone looked at the entire site linked in the post? Friggin' amazing how much time this guy has spent (since '99) collecting information about, well, stuff. All types of stuff, but mostly geek-type stuff. I thought it was fascinating. Go Bob.

The eye!

as opposed to the catalog of scandalous corruptions that we have to live with today. Computer memory prices go up? Computer device prices should always be going down in comparison to what you get. F*ck the cartels.

What do you think? 1970s Pr0n stars or computer salesmen? You be the judge!

In this picture which one do you think is the compsci geek and which one is in league with the devil (aka the Marketing guy)?
