Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks – some even 1,700 years before. Was Leonardo a copycat?
Yosemite Valley is a land forged in wildfire and sculpted by water, and the delicate balance of these two elements is essential to the creatures and trees that call this land their home. But with climates changing and temperatures rising, the Sierras are under siege. Water is scarcer and the threat of fire is more common. Join scientists and adventurers as they trudge through mountains of snow, climb trees as tall as buildings and soar high in the air to spy just how these global changes are affecting one of America’s greatest wildernesses.
The Vikings were among the fiercest warriors of all time. Yet only a select few carried the ultimate weapon of their era: the feared Ulfberht sword. Fashioned using a process that would remain unknown to the Vikings’ rivals for centuries, the Ulfberht was a revolutionary high-tech tool as well as a work of art. Considered one of the greatest swords ever made, it remains a fearsome weapon more than a millennium after it last saw battle. But how did Viking sword makers design and build the Ulfberht, and what was its role in history? Now, NOVA uses cutting-edge science and old-fashioned detective work to reconstruct the Ulfberht and finally unravel the mystery of the Viking sword.
