    Running

    By tjpapaleo,

    So since I've participated in a sport of running called Cross Country, I think I might talk about the physics I'm doing everyday. Let me "run" you through the basics one "step" at a time! I need to stop hanging out with      Briana. So anyways, everyone hates running, but why? Well, because everytime you step, you exert a big force to the ground and the ground pushes back with an equal and opposite force (Newton's 3rd Law). This pounding on your legs, mainly knees and calves, causes pain in the areas that get the biggest force. Also, you may not believe it or feel it, but air resistance or drag force plays a major role in how fast you may run. So as you know, drag force = -bv, meaning that as you increase your speed,  you increase the amount of air resistance acting on you. If you want to increase your speed by 2 miles, you have to work twice as hard to beat drag force. So that's all on running for today. Tune in next time where we hit more everyday physics.

    String Theory

    By tjpapaleo,

    Going back to theory based physics, we now have to look into what String Theory is now. So, to start off with a general idea of what it is, String Theory is the idea of one-dimensional objects called strings are able to move through space and time and interact with each other. Meaning, the idea of String Theory is the idea of multilevel universes living amongst each other. String Theory can also get into various subject (to solve problems) such as black hole physics, early universe cosmology, nuclear physics, and condensed matter physics. A big problem with the theory is that the full theory does not have a full definition for all circumstances. Also, the theory describes multiple universes, which has created problems involving particle physics based on String Theory. So, that's all for now on String Theory. I will address more later (maybe) but for now tune in for more physics on reality.
