Dinosaurs and weight


The beauty of time, is that we can review the things and in case, rectify it, however the popular culture is responsible of to encase the aceppted precepts from the beginning, making continue in the minds of all us, the wrongs precepts, even after years of be know that is wrong.

The spinachs are not so nutritive, was erred in decimal point, giving it 10 times more nutritunional value. In schools is still seen the Börh's atomic model, which only it work for hydrogen atom, but after years has variations in Sommerfield and Schrödinger's atomic models, even the matter conservation law of Lavoisier was refuted by mass and Einstein's energy equilvalence.

Now is the dinosaurs turn, the magazine "Jornual of Zoology" of the london  Zoology Society, indicates that scientifics has rectified about the dinosaurs weight, and they have reported that dinosaurs were not too big as previously thought and now have been stereotyped in many movies, now have been discovered mistakes in ecuations used for calculate its weight since 25 years, making it decrease even half on its tonnage.

The animal leg diameter is directly proportional to its corporeal weight, is therefore as bigger was a dinosaur, its feet would had bigger volumen insomuch that it was imposible to walk for many dinosaurs. The model exact volume is got by water amount that is displaced of measurer cylinder, and the volume becomes to weight throught a factor that represent the proportion volume/weight of the crocodile meat. After make a scale with de size when the dinosaur were alive.

The ecuations becomes more difficult when is about a animal in movement, and acquires difficulty directly propotional to the speed of itself. These ecuations has been partly corrected, but still are inaccurate, with time exist the posibility to have a significant improvement.

The problem is if these corrections has got take in account in books, magazines and above all, movies, since in cited examples in beginning of this articule, still continue extending in our culture and giving us a wrong information about our world. Which we will transmit to next generations.
