Swirling patterns in the ice of Mars’ North Pole suggest the planet is emerging out of a long ice age that began some 370,000 years ago. The findings are extremely important for climate change, improving our understanding of both Mars’ and Earth’s climate.
Look no further than Archimedes for the embodiment of a man ahead of his time. Even among his peers, who practiced philosophy, arts and established democracy more than two thousand years ago, Archimedes of Syracuse outshined them all.
Some might be surprised to learn that the country’s entire nuclear arsenal is still programmed on floppy disks, and army personnel is still reliant on the antiqued IBM Series/1 computer to implement the launch codes.
The induction motor is one of the most important inventions in modern history. It turned the wheels of progress at a new speed and officially kicked off the second industrial revolution by drastically improving energy generation efficiency and making long distance distribution of electricity possible.
In vacuum, light always travels at a constant speed of 299,792,458 metres per second. Nothing can travel faster than this constant c, as denoted by physicists. These two postulates are basic building blocks of modern physics and were first announced more than a hundred years ago by Albert Einstein. Yet, there are ingenious ways to slow light to the point of trapping it in a dead stop. Prepare for some weirdness.
A decade-long study of thousands of Americans has found direct evidence of how air pollution causes heart disease. The link between the two has been established a long time ago, but it’s only now that the biological mechanisms have been explained thoroughly.
It’s the largest any human has come across.
