The United States has debated immigration since the country's founding, and the Statue of Liberty—a potent symbol for immigrants—is often invoked as an argument for why we should usher in those who seek safety and opportunity with open arms. A little-known fact about Lady Liberty adds an intriguing twist to today's debate about refugees from the Muslim world: according to the Smithsonian Institute the statue itself was originally intended to represent a female Egyptian peasant as a Colossus of Rhodes for the Industrial Age. That might be surprising to people more familiar with the statue’s French roots than its Arab ones.
Octopuses have three hearts, parrot-like beaks, venomous bites, and eight semi-autonomous arms that can taste the world. They squirt ink, contort through the tiniest of spaces, and melt into the world by changing both color and texture. They are incredibly intelligent, capable of wielding tools, solving problems, and sabotaging equipment. As Sy Montgomery once wrote, “no sci-fi alien is so startlingly strange” as an octopus. But their disarming otherness doesn’t end with their bodies. Their genes are also really weird.
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.
