Imagine you want to send a rocket to the moon, which is located directly overhead, and because rocket fuel is expensive, you want to do so with as little energy as possible. 

 Would you fire the rocket “straight up” or at an angle towards the horizon?  If at an angle, what angle requires the least amount of fuel?

Sound like an easy problem?  It’s not.   In Launchpad, some of us thought we had the “answer” several times, but this just led to more Richard Feynman-like questions.

In fact, we have a hunch that a thorough explanation of this query will reveal why Einstein’s Theory of Relativity clashes with Newtonian Physics, yet they are both right.

Real Science requires childlike curiosity and sustained effort.  Far more difficult than memorizing answers for an AP test, but far more rewarding and life giving too.
