Our sun was but a fledgling protostar, continually amassing more matter via gravity and steadily cranking up its internal nuclear fusion. There was no solar system, only a giant, rotating cloud of particles called the solar nebula. To figure out how all that leftover gas and dust led to ...
When you deal with massive bodies like the Earth, however, which has a mass of 6 x 1024 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now. The force of gravity acting on ...
And in 1660 Robert Boyle (1627–1691)—now thoroughly committed to the experimental approach to science—published New Experiments Physico-mechanicall, Touching the Spring of the Air and its Effects in which he argued that air has an intrinsic pressure associated with it, wh...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
R&B is not what it was four years ago. When I first started, I couldn't jump off the cliff with all these deep harmonies and chord changes and flavors. I just couldn't do it without being kind of stuck and pigeonholed. I had to figure out a nice balance between what's...
“Earth’s gravity should hold onto the oxygen, and yet, we see this gas shooting off into space. We’re trying to figure out how that works.”Moen adds:“That is a science question that has been hanging around for four decades.”Cusp aurora...
It may seem obvious to people these days, but when he first said it--it was groundbreaking. Whether you look at it in a personal way, or in an existential way, it is so true that it is as obvious and apparent as gravity. Like Newton, we needed Hill to point out something t...
Little to no gravity can affect how rooting materials function. Different rooting materials and soils are better than others when it comes to water and air distribution -- both key to successful plant growth. Out in space, grainy soils can cause water to scatter and fine soils can prevent air...
It's on the underside of the frame, helping to keep the center of gravity low. The gas tank is the only notably heavy component mounted high up, between the handlebars and the seat. The design, then, focuses a lot on weight distribution. With most of the heavy parts mounted at or ...
“The challenge was how to mix the three quotes on the building when it doesn’t have corners, and it’s an oval going up and down,” he says. This was also a challenge for Killa and team. “It took us four and a half months to figure out how to take something flat and stick...
