The arrow of time

I have always loved the strange world of reversed time, but the reversal of the previous droplet movie looks particularly startling. I love the way the the energy of the waves focuses to create the large stationary droplets. The laws of physics on the macro scale are time reversal symmetric so if you could prepare a series of inward propagating waves (say with an oscillating wall), you could create such droplet creation events. Of course the accuracy required to produce a series of such events would be nearly impossible to produce. Still it would be interesting to try...

Woooaaaahhhhhh o.O

We can draw up and down for the first dimension, left and right for the second dimension, and depth and higt for the third dimension.

We can go forward in time, but NOT backwards.

It seems to me that the dimensions below us like the first and second and third that which we live in we can understand and change, but we have to live by the laws of the dimensions superior to us, which means we can't change them. We can only live in them.
