The Discovery of the Wollemi Pine. The Wollemi pine was a critically endangered species when it was discovered by Dave Noble in 1994, and its exact location in the Wollemi National Park remains a closely guarded secret.The botanist Carrick Chambers stated that the discovery was: the equivalent of finding a small dinosaur alive on earth.The Wollemi pine evolved around 140 million years ago, when Australia was part of a super continent called Gondwana, which linked Australia, New Guinea and Antarctica.The arrival of the Wollemi pine coincided with the first flowering plants, and the extinction of the dinosaurs.he botanist Carrick Chambers stated that the discovery was: the equivalent of finding a small dinosaur alive on earth.

Blu-ray disks, however, use a combination of silicon and copper which is bonded during the burning process, this alloy is much more resilient than the organic dye. Manufacturers claim a life span from 100 up to 150 years for Blu-ray disks.â. â = However, these media don't exist long enough yet to confirm or reject those claims. So at the moment, it's about as long as the oldest working DVD/BD is still working. These claims are made assuming the disks are stored properly.
According to the Blu-ray Disc Association, the rotational speed of Blu-ray exceeds that of DVD--by how much depends upon which type of Blu-ray Disc you're looking at. For Blu-ray data discs, the linear velocity (the speed at which the disc surface is moving past the fixed laser beam) is about 5 meters per second, as opposed to 3.5 meters per second on a DVD disc.
