Nuclear Fission or Fusion?

Posted on March 16, 2015 by christophermfitzgerald

Fusion involves the combination of nuclei between two atoms and fission is the process of splitting the nuclei of atoms. When looking at the release of energy from nuclear fission versus nuclear fusion there is a clear winner: Nuclear Fusion. Through … Continue reading → Continue reading →

Where did we come from?

Posted on March 16, 2015 by jamej00

Formation of the Solar System In only the recent history of astronomy, we’ve began to understand that our solar system is in fact no different than other star systems in the universe.  We now understand that stars in fact all form from a collapsing cloud called a nebula, which is composed mostly of hydrogen and… Continue reading →

A Star In a Box

Posted on March 10, 2015 by pgolemanska

A solution to our energy problems? A star in a box. Taking the process of fusion that powers stars and recreate it on Earth can be the road to large quantities of energy with very little pollution and radioactive waste. One of the most efficient ways to generate energy nowadays is a fission reactor, but […] Continue reading →

An Ode to Gravity

Posted on February 22, 2015 by matthewrbirnbaum

Oh, gravity.  You have kept me grounded my whole life.  Where ever I have traveled you have kept my feet on the ground and my head out of the clouds.  I can not see you but feel your presence in all aspects of life.  While some look to defy your laws, I look to embrace […] Continue reading →

The Potsdam Gravity Potato

Posted on February 14, 2015 by revanth111

Source: Universe Today The above picture is a rendering of the Earth’s gravitational field produced by the German Research Center for Geophysics’ Helmholtz’s Center in Potsdam, Germany. Known as the “Gravity Potato,” it shows that the Earth’s gravity is not as uniform as one would think. In fact, the gravitational force is a dynamic surface that […] Continue reading →

Spectacular arrangement of Mars, Venus and the Moon this week!

Posted on February 14, 2015 by agiantchicken

Check that out! Later on this coming week, it is expected that Mars, Venus, and the Moon will come so close to one another in our sky, that they will be separated by less than a single degree in the sky on February 20! While given the moon’s moves along its orbit rather fast around the […] Continue reading →

Black Hole!

Posted on February 14, 2015 by newbeelity

A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it. (Definition from Wikipedia) General relativity indicates that a sufficient density can deform spacetime to form a black hole. The boundary of the region from which nothing can escape is called the event horizon. It has no detectable features when observing something traveling across an… Continue reading →

Special Relativity

Posted on February 14, 2015 by newbeelity

In physics, special relativity (SR, also known as the special theory of relativity or STR) is the accepted physical theory regarding the relationship between space and time.(Definition from Wikipedia) At the end of the 19th century, Maxwell equations of electromagnetism had been proved by plenty of experiments. However, Maxwell equations are not consistent with the Galilean transformations in Newtonian physics. As a result,… Continue reading →

Gravitational Redshift

Posted on February 14, 2015 by farhannshabab

Most of us know about redshifting, a phenomenon of the Doppler effect. This is the change in frequency of a wave, both mechanical and electromagnetic, for an observer when there is relative motion between the source and the observer. For example, when an observer is moving closer to a wave source, each successive wave front […] Continue reading →

The Scale of Atoms and Modern Processors

Posted on February 14, 2015 by conorastr201

Everyone knows that atoms are small, but exactly how small is small? This new video by Kurz Gesagt explores this question, and the sheer scale is mind boggling to try to imagine. Among the analogies used is that of filling rooms with rice grains; if the end of your finger was the size of the room, and […] Continue reading →
