There, scientists can make casts, or reproductions, of the bones and try to recreate the complete skeleton. Scientists can learn a lot from this process: The way the bones fit together gives a basic idea of the dinosaur's shape and posture. Flat, leaf-shaped teeth mean that the dinosaur ...
When you realize that the Earth's magnetic field measures 0.5 gauss, you can see how powerful these magnets are. Most MRI systems use a superconducting magnet, which consists of many coils or windings of wire through which a current of electricity is passed, creating a magnetic field of up ...
A planetary alignment occurs because the planets orbit the sun on a flat plane called the ecliptic, making them always appear in a row somewhere in our sky. But what does change regularly is how many of the seven planets you can see in the line, and the more planets there are, the mor...
Astronauts conduct experiments and improve our knowledge of cultivating plants in space, as well as many other critical arenas of science. Earth-bound researchers and scientists analyze the results and conduct their own experiments, thinking up new theories and possible solutions to test. Before we ...
Confucius did this until he was 30 years old, but he always wanted to do more. He didn’t like the way rulers treated their subjects. He began reading again. He wanted to find a way to help people who were less fortunate than he was. Through many hours of studying, he founded the ...
We’ve been using telescopes designed to reveal the invisible parts of the cosmos for more than 60 years. BecauseEarth’s atmosphereabsorbs most wavelengths of light, many of our telescopes must observe the cosmos from orbit or outer space. ...
On the other hand, I was unlucky that the velocity of impact was mostly endured by the soft and delicate tissues of my brain and neck. The full extent of the damage/dysfunction developed from that incident would not be known for many years, and I am only just learning the complexity, ...
Space.com: I find it very interesting how many ways space makes so many things possible for us here on Earth. Especially when it comes to the medical field, I don’t think we realize how many things that are part of our lives came from research made possible by spaceflight. ...
That exchange opened up a written correspondence. “Praise God, we are all glad to have had contact with you after so many months,” Deborah wrote in a June 2000 email. “You are coming back, you are going to be delivered of the demons that have held you in captivity.” Sarah had m...
fancy flying, fires his weapons, lands his torpedo in the vent, and, with a loud explosion, the Death Star is no more. This climactic scene from "Star Wars: Episode IV" is typical of many action science fiction movies. It makes for a great movie going experience, but is the science ...
