Clams don't have smiling faces – the simile is derived from the longer expression "happy as a clam at high tide." Didn't grow up ocean-side? Here's what it means: Clams are bivalves -- invertebrates sporting a shell divided into two separate sections. They also have a strong foot ...
On Earth, the solar wind is responsible for dazzling aurora light shows around the polar regions. In the Northern Hemisphere the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it's called the southern lights (aurora australis). If solar wind speeds...
Some think the best option is renewables – types of natural energy, such as wind and solar power, which can be replaced as quickly as they are used.Neil Others prefer a return to nuclear energy, arguing that it’s clean, green ...
Modern Earth has a magnetic field called a "magnetosphere" that protects us from the worst effects of solar wind. Mars once had a strong magnetosphere of its own, but it's been substantially weakened over geologic time. This could help explain why the planet's surface looks so desolate today...
Meanwhile, on the cathode side of the fuel cell, oxygen gas (O2) is being forced through the catalyst, where it forms two oxygen atoms. Each of these atoms has a strong negative charge. This negative charge attracts the two H+ ions through the membrane, where they combine with an oxygen...

With continual strong solar wind / interplanetary magnetic field (SW/IMF) driving, latent coupling has the capacity to produce relaxation oscillations of the coupled system. Fast flux exchanges are mediated by electrons and Alfvén waves; slow exchanges are mediated by ion flows, principally O+. ...
Once an earthbag home is complete, you would never guess that the walls are made of dirt. The walls are strong enough to hang cabinets and pictures, and plumbing and electricity are installed just as in a conventional home. Lofts can provide extra space. Earthbag builders Kaki Hunter and Don...
Reflected light - Reflected light, usually in the form of glare (see explanation above), is light that has bounced off a reflective object to enter your eyes. Just like direct light, strong reflected light can make it difficult to perceive the details or directly view an object. Snow, water...
Just like direct light, strong reflected light can make it difficult to perceive the details or directly view an object. Snow, water, glass and white sand are all good reflectors. Ambient light - Ambient light is light that has bounced and scattered in many directions so that it is does ...
