... in 1827 Robert Brown observed that pollen grains in water move in haphazard manner. From a Newtonian perspective, this is surprising as force is required to initiate motion and cause changes in direction. Where does this force come from; could it be that the observed particles are in some sense acti ...

... This experiment uses a vertical shaft that can freely rotate to spin a massive bob of mass m. The bob hangs by two strings from a horizontal bar with a counterweight on the other side. The counterweight helps the shaft rotate evenly. A spring can connect the bob to the shaft and provides a force to ...
