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.
The major difference as pointed out before is the additional capacity that a Blu Ray disc holds compared to a DVD. A Blu ray discs holds 5 to 10 times the memory than a DVD can. Also, the experience of watching a Blu Ray disc video in high definition is unmatched by DVDsâ video quality. About 23 hours of standard-definition (SD) video and over 9 hours of high-definition (HD) video can be stored on a 50GB disc. Another important distinction is in the playing format.
