(PhysOrg.com) -- There was something peculiar about dolphins that stumped prolific British zoologist Sir James Gray in 1936. He had observed the sea mammals swimming at a swift rate of more than 20 miles per hour, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support those kinds of speeds. The conundrum came to be known as "Gray's Paradox." http://www.physorg.com/news146730722.html Physics Mon, 24 Nov 2008 06:32:02 EST news146730722
