How the mighty have fallen. New research proves that the fearsome T-Rex wasn't so fast.
Here's part of a yahoo news story discussing it.
To get a better estimate of the giant's movement, the new study modeled a typical complete T. rex skeleton, which probably weighed between about 13,000 and 17,000 pounds, and estimated its center of mass and the inertia, or resistance to movement, that it would have had when the animal turned or pivoted.
The center of mass is important to consider because two animals with similar weights may move in different ways depending on how their mass is distributed. For example, an elephant’s four tree trunk-like legs keep its center of mass over its feet, while T. rex would have had to balance its mass differently over its two small legs, bending them to keep from toppling over.
The model results, detailed in the June 21 issue of the Journal of Theoretical Biology, also showed that T.Rex would have had considerable inertia preventing it from turning quickly; a 45-degree turn would have taken one or two seconds—far longer than for a human.
These calculations lend further support to previous research indicating that the large tyrannosaurs could run no faster than 25 mph (and certainly not the 45 mph seen in some movies), because its leg muscles weren’t big enough for fast running.
It has a touch screen like the iPhone but it runs on windows instead of OS X.
It looks just like the iPhone. In fact LG is complaining about patent violation, although no lawsuits have been filed.
It's been praised as the iPhone killer, and the Sidekick killer. I don't think it can kill the iPhone just yet though.
