An Introduction

Hey everyone. I don’t expect many people to read this, but I’m doing it anyway. My name is Moez Janmohammad, I’m a physics major at SMU in Dallas, and I’ve made this blog to share my work, research, and other science topics.

Currently, my interests include the search for dark matter, particle physics, and the history of time. I have a strange obsession with relativity, I read everything relating to Einstein’s theories that I can get my hands on. One day, I hope to become a researcher at CERN, but for now, I’ll be chilling at SMU, immersing myself in an excellent physics program. I should be starting research with Dr.Jodi Cooley, as part of the SuperCDMS collaboration.

To the one person that will probably read this, if you have physics topics I should discuss, let me know in the comments below, or send me an email, mjanmohammad@smu.edu

  1. maybe you can explain to me something I have been unable to figure out: when a coin is tossed up into the air and it reaches its peak, how come their is only one force acting on the object (gravity), not two. from my physics class i learned that there always has to be an opposite force, but this example seems to contradict it?

    ps. yes, this was a question on a physics exam.

    1. We know that gravity acts in only one direction, which we define as down. According to Newton’s third law, all forces have an equal an opposite force, but that is only the case for an object that is not accelerating. In the case of an object being tossed in the air, gravity can be the only force acting on the coin because the coin is in free fall, hence the coin losing velocity to a downwards acceleration on the way up, and gaining velocity to a downwards acceleration on the way down.

  2. What is in the future for dark matter research? Since the Higgs Boson particle has been recently found, what is the purpose of restarting the Large Hadron Collider at CERN? How is the physics program at SMU/advice for physics oriented high schooler?

    1. Dark matter research is a very lengthy topic, something I plan to get to in the next couple weeks. The basic idea is this
      -around 4 percent of our universe is baryonic matter, or matter that we can see
      -about 26 percent is dark matter, or matter that doesn’t interact with electromagnetic waves like light
      -about 70 percent is dark energy, an entirely different concept.

      the important thing to know is that dark matter has not been proven to exist. There are quite a few theories outlining why gravity works the way it does in space, and dark matter is just one of many. There is another theory that is widely followed that is based on an extension of newton’s second law (f=ma), proposing that it can be modified for accelerations over great distances, like in space.

      As for the LHC, the discovery of the Higgs was not the end of particle physics. It helped a lot of theories, but there are still infinite things that could be discovered at higher energies. If my memory serves me correct, the LHC is planned to be upgraded to be able to have collisions in the 14-20 TeV range, 10 times more powerful than any other accelerator.
      Some of the stuff we’re looking for includes supersymmetry, momentum loss (which would indicate an existence of dark matter), and various other particles that have been theorized but not discovered.
