Conventional approaches to leg bag emptying involve lifting the leg ontoa toilet seat or leaning down to empty the bag into ...

The quantum analogue of Galileo’s leaning tower experiment is revisited using wave packets evolving under the gravitational potential. We first calculate the position detection probabilities for particles projected upwards against gravity around the classical turning point and also around the point of initial projection, which exhibit mass dependence at both these points. We then compute the me...
