"Eppur si muove" (Yet it moves).

I n the 17th century, the problem of the relative movement of the Earth with respect to the sun was an issue of central importance, and in fact, the man who has been considered responsible for the birth of modern science was committed to house arrest for defending the heliocentric hypothesis. Four centuries after the (never-confirmed) legend of Galileo Galilei’s rebellious phrase, a problem of ...

"Eppur si muove" ("and yet it moves").

Eppur si vola (and yet it flies).

In his book ‘LeVol des Insectes’, whichwas published in 1934, the French entomologist Antoine Magnan mentioned in passing that when he and his assistant, the mathematician André Sainte-Laguë, applied the conventional laws of fixed-wing aerodynamics to flapping wings, they were unable to explain how insects could fly (Magnan, 1934). Thus was born the infamous ‘bumblebeeparadox’,much to the annoy...

Hořava-Witten Stability: eppur si muove

We construct exact time-dependent solutions of the supergravity equations of motion in which two initially non-singular branes, one with positive and the other with negative tension, move together and annihilate each other in an all-enveloping spacetime singularity. Among our solutions are the Hořava-Witten solution of heterotic M-theory and a Randall-Sundrum I type solution, both of which are ...
