What are the benefits of solving a rubiks cube? I know chess is good for Logic, Concentration, Focus, Visualization and all that. However I don't have a chess board but do have a rubiks cube. Does the rubiks cube also help in those areas? More so or less so?

To work out the laplace transform of exp(-as)*(1/s+5) Does convolution have to be used or can s - shifting be used. If s-shifting can be used can you please provide an example of how to use it in this case? My first though was s-shifting but then I would get exp(-as)*(1/[(s-a)+5])...

Wasn't really thinking that far into it, was just thinking about a basic circuit I could build without going into the effects of Quantam Mechanics but thanks away. So say the current comes out of the end of the resistor as the voltage is the same at all points after there (say it is 0V) why...

No potential difference - no current flow. However in a short circuit the potential should be the same at all points however due to the finite resistance of the wire there is a potential difference and hence current flow, on the other hand if we tied to points in a circuit down to the same...

If we have a circuit with one resistor in series with a voltage source like given in the link then at all points before the resistor the voltage is the same, and after the resistor the voltage at all points along the wire is the same, as there is no potential difference between two points before...

On average, how many times do you need to roll six dice together to see all six different numbers turn up within a single such group roll?
