He did enlighten me as to the gravity of our environmental problems. Practically, he talked about how our relentless exploitation has depleted many important natural resources. Moreover, he indicated that problems like global warming also stem from various kinds of pollution, the most severe of whi...
We modified the microsphere-surface distance by changing the angle of the chamber's bottom surface relatively to the horizontal plane: the component of gravity directing microspheres toward the chamber surface was reduced when the angle was increased from horizontal plane (see Fig. 2a,b). ...
