These are all the possibilities I can think of under the above conditions. But I wonder ia we haven't all been going off on the wrong track. If an automobile is travelling at the rate of 80ft per second, and passes another car going 50 ft per second, while the motor is giving a push of 1000 pounds, then the work done relative to the road is 80,000 ft Lbs. per second, and the work done relative to the second car is only 30000 ft lbs. per second. But the work done relative to the second car doesn't count, because the first auto is pushing against the road, and not against the second auto. Why not apply this to the rocket and measure the velocity relative to the thing it pushes against, which is the expanding gasses pushed out from behind. It can be seen that the velocity of the rocket measured with respect to these gases is always constant, one the gases have left the nozzle of the rocket. My knowledge of physics does not permit me to foresee the results of this, so for a couple of years I'll have to let it go at that. Perhaps some of you have suggestions. Letters are exceedingly welcome. TODAY'S LESSONS IN SUPER SCIENCE By Milton R. Rothman Monthly
