Take a boy to the edge of a lake and watch him looking for a stone to send skimming over the surface of the water. Later he grows up into a physicist who somehow manages to get paid for skimming stones. So now we have a new field of scientific investigation. Shin-ichiro Nagahiro and Yoshinori Hayakawa used a virtual lake front called Smoothed Particle Hydrodynamics. This helps them to verify the 'magic angle' for stone-skip. I am glad to note that they give my friend, the jesus-lizard, a mention. It seems he knew all along.
