physical toys: ![]() Levitating pyrolytic graphite over four neodymium magnets (quadrupole) ![]() Nice beta type Stirling engine running with the heat of your hand ![]() Looks like a normal gyro - but.... ![]() it's unstable - precession becomes "stronger" ![]() and at the end it flips. As every cryo it conserves the angular momentum => in the "flipped" position it a the same spin direction as in the first picture :-) |
