Online home of Jeremy Scheff

Welcome to my blog! Here, you will mainly find me writing about whatever interests me at the moment. Since I am a predictably simple man, most of my posts are about sports, science, and programming, with an occasional foray into politics if I'm really bored. My favorite posts include:

All my other posts are listed below, in chronological order.

Side projects galore


God damn, I’ve been neglecting this blog. It’s sad really, because I do have a lot to say. I guess I’ve just been talking to myself instead of blogging lately, which maybe says something about my mental stability, but whatever. I’m blogging now, and I’m going to blog the fuck out of this blog.

It’s 2016. My job is pretty cool in some ways, but in some other ways it bothers me a great deal. It’s probably not in my best interest to go into that in great detail here (as if anyone is reading this, right?) so I will leave the rest unsaid, and just get to the broader point. I am someone who cares a great deal about science, engineering, creating cool things, doing things the right way, etc. And when I say “cares a great deal” I mean probably more than I can adequately articulate with my pedestrian writing skills. It’s almost like a spiritual thing. So for someone like me, what do you do when your day job is preventing you from attaining your desired level of spiritual satisfaction?

Side projects!

The Bishop Sankey Diagram


Or, my best pun ever:

Basic income vs. basic job


Chris Stucchio wrote an article about the differences between basic income and basic job policies, based on relatively straightforward math. Briefly, basic income says give everyone money with no strings attached and get rid of other forms of welfare. Basic job is the same, except anyone who can work is mandated to work, either in a normal job like today or in a New Deal-style government works program.

Chris’s main conclusion was that basic job came out looking way better than basic income. Additionally, a major purpose of his post was to encourage other people to play around with the math as well rather than just bloviating. Since I’m a big basic income proponent and have some quibbles with how he came to conclude that basic income doesn’t look too good, I will follow his lead and play around with the math.

The effect of a blocked jump shot on future jump shots in the NBA

, , , (1 Comment)

If an NBA player gets a jump shot blocked, does it change the way he plays the rest of the game? You can imagine there could be a psychological effect like a loss of confidence, or a conscious/subconscious decision to try harder to avoid being blocked again which could harm shooting efficiency. Basketball statistics legend Dean Oliver recently Tweeted that claim it has a big effect on Steph Curry and basketball players in general. But is it actually true? And how big is the effect? Let’s look at some data.

The Large Hardon Collider


The Large Hadron Collider is a marvel of modern technology. It is also an endless source of juvenile amusement, since the word “hadron” is very similar to “hardon”. The Large Hadron Collider was built by the European research organization CERN (“CERN” means “science” in European). At CERN’s official website, there are currently 141 articles which mistakenly use the word “hardon” instead of “hadron”. The first result is the title of one poor fellow’s PhD thesis.

Model-based insights into distinguishing cortisol profiles in depression and post-traumatic stress disorder (PTSD)



One of my main scientific goals is the application of mathematical models to find interesting insights into biological systems. This is a really broad goal, as depending on the area, there may be very different ways to gain insight. Here, I want to discuss one example, an interesting paper by Sriram and coworkers that was published in PLOS Computational Biology last year entitled “Modeling cortisol dynamics in the neuro-endocrine axis distinguishes normal, depression, and post-traumatic stress disorder (PTSD) in humans”.

Did Adrian Peterson actually rush for more yards than Eric Dickerson but have it go unnoticed due to measurement error?

, , , (1 Comment)

Despite miraculously recovering from ACL surgery and successfully leading his team for the playoffs, Adrian Peterson tragically missed the all time rushing record by 9 yards.

…or did he?

Let’s think about how the NFL measures yardage. They take the difference between where the ball was before the play and where the ball is after the play, and then they round to the nearest integer. What happens if you rush for half a yard? It’ll get recorded as either 0 yards or 1 yard. Spread out over an entire season, and this kind of rounding error can have a big impact.

Things I wish I knew about food and cooking 7 years ago


7 years ago, I was an undergrad moving into my first apartment with a kitchen. Two of my roommates had a crazy idea. They wanted to not get meal plans and instead just cook all our food. My other roommate and I thought that was ridiculous, but we were at least willing to give it a try. That turned out to be a fortuitous decision for me, as I found that cooking allows me to make healthier, tastier, and cheaper food and it’s actually pretty fun.

Vote and die: are you more likely to cast the deciding vote in the election, or to die on your way to your polling place?

Vote or die? Or, vote and die?

Here is a calculator that will compare the odds of your single vote swinging the 2012 US presidential election with the odds of you dying on the way to your polling place.
