In the film series, many of the dragons are shown to have unique types of breath weapons and fire types. These differences make the dragons attacks much more varied in combat style. This ability differentiates them from other organisms, and enables them
Then the guide taught us how to make a model 今天我继续学校旅行。 我们参观了科技馆,并且它是真正地有趣。 我们达到目的那里很快速通过火车。 我们看见了有些农场和村庄。 在博物馆,我得知很多机器人。 我不知道他们可能下棋与我们。 很凉快的! 然后指南教我们如何做一个式样机器人。 我采取了很多伟大的相...

They have been known to fall asleep while flying, waking only when they crash into the ocean or the side of a mountain. Gronckles have relatively small wings that beat as fast as a hummingbird's. They are slow in the air, but make up for this with their maneuverability. A Gronckle ...
This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust. Maglev trains float on a cushion of air, eliminating friction. This lack of friction and the trains' aerodynamic designs ...

With a speed range like this, a locomotive would need 20 or 30 gears to make it up to 110 mph. A gearbox like this would be huge (it would have to handle 4,200 horsepower), complicated and inefficient, and create a possible point of mechanical failure. It would also have to provide...
How is a magnetic field created? How long does it take a 19k W steam engine to do 6.8*10^7J of work? How do airplanes fly upside down if it's the shape of the wings that make them fly? What is an optical fiber and how does it work?
resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become cor...
