RADIOMETER, POND
Text: 09/24/04 experiment 1) When placed in front of a radiant electrical heater, velocity is minorly increased but stops when radiometer is heated. 2) Light impacting white stops motion. 3) Light impacting black increases motion. 4) When radiometer is initially cooled motion increases in same light. 5) Radiometer when placed in cool water then placed in front of radiant electrical heater (heating up) will spin with increased motion but when gas has heated up will stop altogether then reverse its motion (cooling down) once taken from front in front of radiant electrical heater. 6) "Light incident to any body that absorbs or reflects it does not press upon it. The radiometer of Professor Crooke's invention is not operated by the pressure of light, but by corpuscular bombardment on the reflecting side of its vanes." Keely, Snell Manuscript The above sounds like our experiment when kids we threw stones in pond water BETWEEN a floating object and the shore where it would eventually arrive. If stones were thrown beyond the object it would go to the site of impact (away from the shore). There is something about an explosion that is attractive to neighboring objects. See implosive effects of large explosions being greater than their initial repulsive/expansive forces. Perhaps like a SAW-TOOTH wave form???
