The twin paradox is completely misrepresented here. The paradox is special relativity says all motion is relative and therefore the clocks could both be correctly said to be moving slower relative to each other and therefore both twins would be older than the other. The solution is special relative ignores acceleration, but you must take into account the acceleration of the rocket which requires general relativity. It's embarrassing a university could get such a well known problem so wrong.

The tortoise and Achilles one is dumb. It all depends on the total distance and the tortoise head start. Obviously this could be worked out but where is Achilles starting? 20 miles away when the tortoise is a hundred feet or something? Waste of math and time. Who cares
