This is a fairly current me.
The picture below is a 4-space cube or tesseract. N-space cubes contain all sorts of fascinating symmetries. The sets of colored lines create lesser n-cubes within the tesseract. Things like cubes, squares, lines, and points are all sub-space cubes of the tesseract.
If your browser is set to see animated pictures the colored lines above will
appear and disappear.
They make pretty pictures, but what do they mean?
A fifth grade student can draw a 5-space cube once they are shown how. And with a bit of high-school binary math you can create N-cubes of any dimension. This is a 5-space cube. If you click on the 5-cube, it will show you a monster 8-space cube.
This is the Chinese Ring Puzzle. The object is to get the blue wire
handle off of the green-ring thingy.
The order of moves to solve the puzzle is a Gray Binary Counting Sequence discovered several
hundred years ago.
The Chinese invented the puzzle several thousand years ago.
I've always wanted to fly. I think Hang Gliders are the most fun way to fly. It's a real thrill when you hit a thermal that puts you on an UP elevator at more than a thousand feet per minute. Yes. They can go Down that fast too.
I'm paraplegic, (can't walk) but I can still water ski, snow ski, kayak, swim, crank a handcycle and even fly a hang glider.
I have had the pleasure of playing the cello in small string ensembles and I used to play in the Oak Ridge Symphony Orchestra (ORSO).
My Amateur Radio callsign is WB4UFG. These days, everyone uses cell phones, but in an emergency such as a tornado, Ham Radio is sometimes the only reliable communications available.
In addition to my personal website HowToAdapt.com, I enjoy designing websites like CCOR
and the Knox County disAbility Resource Center.
Working on them keeps me out of trouble - most of the time.
