Re: Tricky Box Problem

Spoiler:
The box [imath]0\times50\times1[/imath] fits inside a [imath]1\times1\times1[/imath] box so yes it is possible if you allow the box to have a volume of zero.

Re: Help! I'm trying to get a 14 year old interested in Maths.

Re: The fastest you can go.

Are you asking in what speed will the length dilation (of the craft) affect the time (for an external observer) so that it will appear to take a longer time to travel from A to B? If that is indeed your question the the answer is never. The length of the craft (in the direction of the speed) wont de...
