T = E^-1
wherein T = Time and E = Energy
In short, time is the inverse of energy, and energy is the inverse of time.

Ever hear of the time-space continuum?
Here is the wikipedia site:
http://en.wikipedia.org/wiki/Time_space_continuum

What does all this mean you wonder?

Simple: if I have the time to do something, then I don't have the energy. Likewise, if I have the energy to do something, then I don't have the time.

Concrete examples:
I have the energy to mop my floor around 2 pm on a Tuesday afternoon. However, I am at work when this happens, so I don't have the time.
I have the time to mop my floor around 2 pm on a Saturday afternoon. However, after a 45-50 hour workweek + spending all Saturday morning shopping for groceries, running errands, waiting in line at La Poste, etc. I don't have the energy. All I have the energy for is a three-hour PASSED OUT ON THE COUCH major nap session.
See? Time-Energy discontinuum.

I don't think this time-energy discontinuum will go away in the near future. Maybe once we retire. At which point, there will most likely be a (time*energy) - health discontinuum. Yay for the rat race!

Found out, in true French Bureaucratic fashion, that I have been accepted to the program and will be starting next week. Still haven't received the official papers and it starts less than a week.

I demand to be cited as the original discoverer of this Time-Energy Discontinuum for all future scientific articles.
