# What does the Steak N' Shake Time Machine commercial's “smart stuff” mean?

I would like to know if there is any physical/mathematical significance to the following expression:

$$m\left(\left.\gamma v^{2}\right|_{t_{0}}^{t_{1}}-c^{2}\int_{v_{0}}^{v_{1}}{\frac{2v/c^{2}}{2\sqrt{1-v^{2}/c^{2}}}\:dv}\right)$$

For reference, starting at 21 seconds

Does this equation have any real meaning and if so, what does it mean? I do notice an integral.
