'Cartouche' is actually a French word meaning 'gun cartridge'. When Napoleon's soldiers were in Egypt, they nicknamed this shape 'cartouche' because it reminded them of the shape of their gun cartridges, or bullets. At the time, people could not read hieroglyphic writing, so they did not know that the cartouche surrounded the name of the pharaoh. 'Cartouche' became so commonly used that it has remained the standard name for the shape around the name of an Egyptian pharaoh or queen. Were royal names always written inside cartouches? In the first three dynasties, royal names were written inside a rectangle called a 'serekh'.
Maximum Speed. The maximum swimming speed for humans is approximately 2 meters per second, or approximately 4.5 miles per hour, Dutch researchers Huub Toussaint and Martin Truijens reported in the journal Animal Biology in 2005 â only 16 percent of the maximum land speeds of elite human sprinters.
How fast can fish swim? I seriously question the speeds often given for any fish, especially when Wikipedia and some reputable some encyclopedias claim that sailfish are supposed to be the fastest fish and can hit 60 miles per hour. I once went to several references and online sites looking for Orca speeds. I found a range of speeds from 25 to 35 miles per hour (from here on shortened to mph) on the publications and web sites. None were anywhere near as fast as some the speeds some fish can supposedly attain. Since Orcas can run down, catch, and eat, blue fin tuna, I question all the old, unsubstantiated fish speeds.
