African-Americans in astronomy and space
By: Rex Coker
Ronald Ervin McNair born in Lake City, South Carolina on October 21,1950 gave many blacks in the deep south the dream they yearned for. A stand out in his school for academics, Ron chased the American dream. He used his brain as well as...
Isaac Newton's Three Laws of Motion
By: Ernest Washburn
Newton's first law (law of inertia) states that an object in motion continues to stay in motion and an object at rest continues to stay at rest as long as no outside force acts upon that object. Although the law is named after Newton it...
Isaac Newton's Three Laws of Motion
By: Jesse Delia
Newtons 3 Laws of Motion are as follows...1. The Law of Inertia - "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force."This means, an object tends to 'keep doing what its doing', until...
Space exploration in the future
By: Dave Powell
For future space exploration, I'd like to see telescopes whose images can be digitally filtered in real time by very fast computers. You could do a lot of neat things with them. Yes, most of today's telescopes are already computer controlled. But this control is...
The super C velocities debate in Physics
By: Dave Powell
Scientists continue to debate faster-than-light speeds, and to search for the subatomic particles known as Tachyons. These particles would theoretically travel faster than light in air, water, space, or any other medium, and would have real energy but imaginary mass (based on the square root...
Atomic physics: Quarks and anti-quarks
By: Ernest Washburn
Quarks are one of two groups of fermions. There are six different 'flavors' of quarks but only two occur naturally in the modern universe. These are the up and the down quark. The up quark has a charge of +2/3 and is the lightest of...
Astronomical determination of Passover date
By: Tziona Yisrael
What better time to post this topic than now in preparations for next year's Passover. Too many people believe that a "barley search" is in order before we can identify the start of the Hebrew New Year, but nothing could be further from the Truth...
By: Joe Makintosh
It is every six year old boy's dream, but only the select few of them are chosen to represent their country, even the world, and make history. However, being an Astronaut is not easy, it involves intense training and being forced to their physical limits...
An overview on how astronauts are trained
By: Susan Klatz Beal
When NASA is considering astronauts for the Astronaut Candidate Program, they look for people who have varying backgrounds. Mission Specialists are typically people who have training as engineers, physicists, mathematicians, or other areas of science.The commander and pilot of the Shuttle Missions, each of...

Is time travel possible? If it were possible, should we be allowed to go back in time, and change the past? Would we even want too if we knew that we could? Time travel in theory is possible, but it is so complex, and involves...
