Anyone can learn physics. Think, for a moment, about your everyday life. You know quite a bit about the way the world around you works. You know that when you drop your keys, there is something called gravity that causes them to fall. You know that the things around you have mass, and you have […]

I only recently started learning physics. My first real physics class was a course on classical mechanics, which I took in the Spring of 2012. I would never recommend anyone start learning physics the way I did, but I was under quite a bit of pressure to graduate, and decided to rush right in. My […]

There is a big debate in metaphysics regarding how material objects persist through time. It seems clear that objects really do persist in some commonsense way – I’m not sure whether anyone debates this – but most philosophers are divided between two views on what this means. The first view is known as “endurantism”, and […]

Here I am, getting ready to pull an all-nighter studying for my grad quantum mechanics and mathematical methods in physics finals. By anyone’s standards, I shouldn’t be here. In fact, I shouldn’t be studying physics at all. Up until a year and a half ago, I had never studied physics. Ever. In addition, I had […]

                A few months back, I picked up Greiner and Mueller’s Gauge Theory of Weak Interactions and Greiner et al.’s Quantum Chromodynamics. Now that the semester is coming to an end, I’m going to finally have time to start working through them. From what I have worked through so far, they are […]

In my earlier posts, I mentioned several times that axions don’t interact very much with the particles in the standard model, with the exception of photons. Awesomely enough, not only can axions decay to photons, but photons can decay to axions as well! This is called the Primakoff Effect (and Inverse Primakoff Effect): when axions […]

In cosmology, the roles that axions play are pretty complicated, but I’m going to try to do my best to explain them. 80% of the matter in the universe is made up of “dark matter”, and we don’t really have any idea what it is. A lot of cosmologists think that, along with dark energy, […]
