The history fission and fusion is rather short and very convoluted, so a brief description of the two processes is a good place to start. Simply put, "fission" is a nuclear process in which an atom is split (or decays) to form two smaller atoms...

I think we've all spent time, periodically in our lives pondering this idea. And how we might manipulate it to go back a few years and reverse some traumatic event, or personal failing or regret, or even just to make billions on the stock...

What happened 1 second ago is history, we cannot change it no matter what we do. What will happen 1 second from now is the future, we also really have no control of the future so we cannot change it, just prepare ourselves as well...

Perception is an integral part of the human experience. It is the hammer and nails we use to build our reality; to both see and interpret the world as we see fit. Time, a concept as ancient as our species, does not escape the unforgiving...

Apollo 1 CrewSpace flight is dangerous. Astronauts are sitting on gigantic tubes packed with explosive materials. Spacecraft move dangerously fast, making a collision inevitably fatal. Spacecraft fly through a deadly, inhospitable environment of vacuum, radiation, and extreme cold. By contrast, the heat generated by re-entry...

To understand Newton's three laws of motion it is worth considering the history leading up to his discovery, to see the background to his ideas. Thinking about motion stretched right back to ancient Greece, where the views expressed by Aristotle on the subject would come...

When faced with a redox reaction, sadly, you can't rely on the atoms and molecules alone to guide you in balancing. There will often be multiple solutions that appear to be right, yet don't reflect chemical reality. To make sure that you get the...

Oxidation numbers do not have a true physical significance in the real world, but they are tremendously useful as a book-keeping method when estimating oxidation states. In practice, students utilize oxidation numbers most frequently when balancing redox reactions (see the article "How to Balance...
