I participate on this site because I really enjoy physics and because I would like to learn more about what makes an online community work well. Questions often interest me more than answers – although I think the best answers are grounded in observation and experiment. I’m optimistic that there are still many surprising discoveries yet to be made in the physical sciences. I believe physicists should be good citizens. I believe my children will know things about the natural world I can’t even imagine – and will learn them in ways quite different than how I was educated.

What determines the angle of the cushion on a pool table? This analysis claims the 'sweet spot' of a pool ball is (7/5)r . I would have guessed that height was the reason for table design, rather than a particular angle. |

Michelson–Morley @ Home I honestly don't recall how far we took the lab in class or what the precision was (I did this as a student a long time ago!) but it was an actual laboratory using lasers performed as part of a unit about the 'classic' MM experiment to measure the aether. |

What is the most optimal earth's axial tilt in terms of variation of seasons? Uranus has an axial tilt of 97.77 degrees. I can imagine an exoplanet being discovered with a similar tilt. It would fall to physics to discover the tilt and then try to predict what impact this would have on climate. If the planet was otherwise earth-like there would be great interest to understand the impact of axis tilt on habitability. |

How much information about the scale of a waterfall can be obtained from its sound? Thanks for sharing your experience. I find it always interesting to hear from someone that is actually performing experiments! |

What is a strain gauge and how do I use one? +1 for fine description of most common type of strain gauge. Comment just to point out that many other unconventional designs are possible as well. |
