A basic statistical analysis of the Physics GRE

So I am going to talk a bit about the Physics GRE. This is a test I spent many hours of my life studying for. I personally scored a 56 percentile on the official test, which isn't terrible. On practice tests I scored from the 30's to the 80's, depending on the test, averaging out in the 60's somewhere. The top of one of the practice GRE Physics tests. This particular test is test GR1777. The practice test can be found on the ETS website https://www.ets.org/s/gre/pdf/practice_book_physics.pdf Usually the people that I have seen defend this test are those who did well on it. To be frank, even though I was getting decent scores, I don't like this test and I do not think that it is a good indicator of talent, ability, or knowledge. I also have a reason for this which is valid regardless of your position on the matter, the reason being the spread of my scores. A question I ended up asking myself was, "Is this massive spread just happening to me? Do all p

What life is like as an observational astronomer

Hi to whoever is reading this! I don't know how you found this, maybe you know me and decided to check out this blog. Maybe I shared the link and curiosity got the best of you. Maybe you are curious about what the work life of an observational astronomer is like and started to research it. Maybe you have no idea how you wound up on this page. This is actually my first blog about what I do, partially because I've always wanted to share about the work I get to do, but have never gotten around to it. This job is an introverts dream, while simultaneously being an extroverts nightmare. Luckily for me, I'm a natural introvert, so I'm pretty okay with how removed from society I currently am. But it also so freaking cool what I do (I'm literally helping study the universe!), that I really want to share. I guess it might also help me stay slightly more sane talking about some of the stuff I do. The view Out of everything, one of the coolest thing about my job is the ab

Some Philosophy on Politics With a Statistical Analysis of Polls

Listen, if you don't want to read about my political musings or the assumptions I put into this analysis, you can skip to the first graph I made and the results section. The truth of what Polls actually mean I think a good example of a biased political narrative, regardless of political slant, is attempting to use polls to paint a political narrative. One thing I hear often in some form or another is, "The polls show that Joe Biden is ahead and that means he will win!" and the response to this is often "Well actually, Hillary Clinton was ahead in the polls and lost and that means the polls are inaccurate and meaningless." Both of these statements contain truth. Joe Biden is currently ahead in the polls. This does not mean that the polls are saying he will absolutely win. It's also true that Hillary Clinton did indeed lose four years ago even though she was ahead in the polls. That doesn't mean that polls are meaningless. If conducted scientifically we
