Re: Mechanical/Electrical Off-Season Projects

I've been doing a little web research on bicycle frames and I now think that alum may not be the best choice for a bike that will see a lot of use and mileage. From what I have read, steel tubing has...

Re: Mechanical/Electrical Off-Season Projects

I mentioned in another thread last year that I was working on ideas for a recumbent bike, and I would post my plans when I got around to building one.

Re: Ideas to move in the direction of making FIRST competitions 'fair'

I think your data proves the point that FIRST is not a fair competition. Since each team only contributes 33% of the makeup of each alliance, how can any team expect to have consistant match results,...

would there be a continuity of history going back 50k years? would they know we had the technology to launch a device like this?

Re: Send a message to humanity 50,000 yrs from now

The pyramids have more evidence of being 3 to 5k years old

but the Sphynx could be much older. One theory says it was originally a lion, and the egyptians reformed it to change the shape of the head.

Re: Ideas to move in the direction of making FIRST competitions 'fair'

that was true in the past, but for the last several years winning a regional also meant you could go to the championship. For some teams, if you dont win, you cant go.

you are correct, in the normal sense of physics and math, even when you run into a brick wall you do not experience infinite acceleration to zero velocity. therefore as your velocity dropped to zero...
