Equal and Opposite

Posted on February 17, 2014 by hindsolar

Newton’s third law of motion tell us that for any force that is applied there is always an equal and opposite force. Physics and Astronomy are tightly intertwined. I thought the example of a plane captures this idea and is quite interesting. Planes must maintain certain altitudes. This is controlled by the wing of the […] Continue reading →

The Kessel Run

Posted on February 17, 2014 by colepospisil

In Star Wars: A New Hope, Han Solo claims to have made the Kessel Run in only 12 parsecs. It is at this point that a general outcry raises from the physicists who know that a parsec is a unit of distance, not time. But when one knows more about Star Wars, it all makes sense. […] Continue reading →

Zero Gravity

Posted on February 17, 2014 by colepospisil

Planets are like ogres, they have layers. As you approach the center of the planet, mass is skimmed off until the effective mass of the planet is zero at the center. At this point, the planet’s gravity affects you in equal and opposite directions, so there is essentially no gravitational force. Everywhere other than the […] Continue reading →

E=mc² is Incomplete

Posted on February 17, 2014 by gradytlynch

This brief and to the point video breaks down the nature of Einstein’s famous equation E = mc^2. Using the simple analogy of a right triangle, it shows how an object with mass can never achieve light speed. In everyday life, the “pc” component of Einstein’s equation doesn’t matter, as objects can rarely travel significantly […] Continue reading →

Interfer… What did you say again?

Posted on February 17, 2014 by blankster22

To this point in history, we have created some pretty impressive telescopes. We are now able to see things that we could scarcely have even conceived of a hundred years ago. But even with the incredible advancements we’ve made so far, there’s good reason to think that we can even make what we have now […] Continue reading →

Archaeoastronomy

Posted on February 17, 2014 by Leigh

Archaeoastronomy is a relatively new field that combines the disciplines of archaeology and astronomy; in it, scientists piece together the astronomical discoveries of ancient people by analyzing the remains from their civilizations. It is a very interesting and informative field … Continue reading → Continue reading →
