The latest global arms race has gone hypersonic. Capable of flying faster than 5000km/h without losing manoeuvrability and lower in the atmosphere than traditional ballistic missiles, hypersonic weapons will offer clear advantages in penetrating missile defences — once they’ve actually been perfected. Though still in development by nations around the world, once fully operational, the missiles are expected to be capable of destroying targets anywhere on the planet within an hour of getting data and permission to launch. The weapons will also lessen the timelines for a response by a nation under attack.
Leonardo da Vinci liked to think that he was as good at engineering as he was at painting, and though this was not actually the case (nobody was as good at engineering as he was at painting), the basis for his creativity was an enthusiasm for interweaving diverse disciplines. With a passion both playful and obsessive, he pursued innovative studies of anatomy, mechanics, art, music, optics, birds, the heart, flying machines, geology, and weaponry.
There are several characteristics of the changing climate that are helping to increase the risks of damage from Hurricanes, even though global warming is not directly causing such a storm to spin up. Katharine Hayhoe, a climate researcher at Texas Tech, put the relationship between climate change and storms such as Florence as follows: "Hurricanes are absolutely being affected by our changing climate, in many ways. As the world warms, the rainfall associated with hurricanes is becoming more intense; they are getting stronger, on average; they are intensifying faster; they are moving more slowly; and, as sea level rises, the storm surge from these events can be more damaging."
Margareth Geertruida Zelle ( August 7, 1876- October 15, 1917) is the most famous and controversial spy of World War One.
