They plan to have a rooftop garden on top when the construction is done. It was featured on NOVA. It's a huge project and will save a lot of time getting from place to place. I did not know that London was the first place to feature below-ground transportation. I thought it was the subway in New York but no. Any idea how much it will cost when completed? Will you be able to take advantage of it? less

I use TinkerCAD to make a lot of my projects, but I learned AutoCAD as well, but I need to learn SolidWorks and Sculptris if I want to learn how to truly make things :D

It's among the fastest manmade objects. Not counting for the fact we're traveling at 220 km/s around Sagittarius A* (black hole at the center of our galaxy), and everything on earth as well. You know what I mean :P
You can go ahead and post all of your politics crap. Politics are important but y'all are still taking this circus too seriously, so I'm spamming some science to settle the scales with some seriousness :P less

So for a period of time, it'd look as if, for the southern hemisphere, there were two suns in the sky. A Type II supernova would only be a fifth as bright as a Type I supernova and would last FAR longer. Sadly it'll be a couple billion years before this even has a chance of happening, and the sun will be long dead. The sun will have a relatively quiet death, just hazing out into a planetary nebula with a white dwarf at the center. Gosh space is sexy :D less

Any magical power or process of transmuting a common substance, usually of little value, into something of great value.

Think on it."Scientists Greater than Einstein"" tells the stories of ten scientists whose discoveries have had an amazing impact on humanity. Combined, these ten scientists have saved more than 1.6 billion lives--and yet, most remain unknown and unheralded. For instance: Do you know about the eye doctor who in the 1970s figured out how to save millions of children with a nickel's worth of medicine? How about the man from the dusty fields of Mexico who has saved hundreds of millions of people from dying of starvation and malnutrition? Everyone knows about Jonas Salk and his polio vaccine. Do you know whose discovery made Salk's vaccine possible and who created the measles vaccine that has saved many more lives than the polio vaccine? Much of the world's population is alive today due to these ten scientists and no one knows their names. Scientists Greater than Einstein will correct this oversight. less
