# Turing Machine Runs »

A Turing machine is a minimal idealization of a computer. It consists of a line of cells known as the tape with an active element called the head that moves back and forth on the tape and changes the color of cells according to a set of rules. For various initial conditions (x-axis), the plot shows the number of times the head changes direction in the first 50 steps of the evolution of the Turing machine. For this Demonstration, 4096 Turing machines in each of four classes have been randomly chosen.

How do we know if a rose is real?

If it looks like a rose, but you
touch it and it's in two dimensions,
it's only a photo.

# Maurer Roses »

The graph shows a walk along a Maurer rose in steps of d degrees (including rotations) with either n or 2n petals, according to whether n is odd or even. Varying z scales the degrees.

# Sputnik 1 Orbiting the Earth »

October 2007 marks the 50th anniversary of the launch of the Russian satellite Sputnik 1, the first human-made object to orbit the Earth. The satellite was carried into orbit on a Soviet R-7 rocket and had a height of 228 km at perigee (closest point to Earth) and a height of 945 km at apogee (farthest point from Earth). Its velocity at perigee was 8 km/s and its time for completing one orbit was 96 minutes. Sputnik 1 stayed in orbit for three months before falling to Earth in January 1958.
