4. Will we be able to predict catastrophic weather events (tsunami, hurricanes, earthquakes) more accurately? 4.我们是否能够更准确地预测灾害性事件(海啸、飓风、地震)? 5. What happens if all the ice on the planet melts? 5.如果地球上所有的冰融化会怎样? 6. Can we create an environmentally fr...
Because Mars has no magnetic field, humans would receive whopping doses of cosmic radiation — not a problem on Earth, where the planet's magnetic field works to block it out. A 1,000-day trip to Mars has the potential to result in a 40 percent chance of the astronaut developing cancer...

Enlarge the outline of the map to fit a large sheet of poster board. Copying the map on a transparency and projecting the image onto the wall with a projector is a quick way to create the appropriate size image. Simply trace the outline onto the poster board. You can also enlarge the i...
When the matter is that of romantic or erotic attraction, we look to Venus and Mars. Along with any aspects made between them, the astrologer checks to see if electric, disruptive, exciting Uranus factors into the quixotic calculus; or do Pluto's magnetic and possessive tendencies show up?
Electrified charging coils (线圈) will be buried under the concrete roads that will create a magnetic (磁性的) field on the surface of the road. This technology is similar to the technology used for developing wireless charging stations for tablets and phones. Cars will be fitted with a receiv...
Magnetic storage rings: Antimatter must remain separate from normal matter so storage rings with magnetic fields can move the antimatter around the ring until it is needed to create energy. Feed system: When the spacecraft needs more power, the antimatter will be released to collide with a targe...
Auroras occur on other planets, too — all that's required to make an aurora is an atmosphere and a magnetic field. "Auroras have been seen in the atmospheres of all the gas giant planets, which is not surprising, since these planets all have robust magnetic fields," said Jeff Regester,...
energy states of the reactants (the inputs of a chemical reaction) or the products (the outputs). Instead, they in effect create a smoother path from reactants to products by lowering the amount of energy that needs to be "invested" in order to receive a "return" in the form of ...
Silicon manufacturers, homebuilding materials manufacturers and space agencies have all put aerogel to use. Its popularity has only been hindered by cost, though there is an increasingly successful push to create aerogels that are cost-efficient. In the meantime, aerogels can be found in a range ...
