When I am on Twitter, every now and then a witty or funny tweet catches my attention. I laugh, and sometimes re-tweet. More often, however, I read tweets that cause anxiety and make me frown at my computer screen with the countenance of a distraught fish. I am talking about tweets like this one (Fig…. Read more »
Scientific Methods and Techniques
A new method of addressing mental health and crime
Imagine your friend, Alex, has bipolar disorder. Alex feels like the medication he has been taking gives him headaches and that getting high on pills works better, and he chooses to stop taking it as a result. Very soon, Alex’s symptoms begin to come back. To you he seems anxious and maybe even impulsive, but… Read more »
Climate change: Adapt or die
My research is dependent on migratory birds being present on their wintering grounds in the Appalachian Mountains in the month of March. But this year it was an unseasonably warm winter, and it was not possible to know when migrants would depart for their breeding grounds. Luckily, the temperatures dropped again and the migrants hung… Read more »
This is your brain on electricity
In the famous Milgram Experiment, it only took commands from a purported authority figure to get people to subject another study participant to electric shocks up to 450 volts (about a quarter of the voltage used to execute people in the electric chair). In reality, the other participant was an actor, and there were no actual… Read more »
Globular cluster simulator: Can your PC handle it?
If you are a video game enthusiast, you might be familiar with the importance of the graphics processing unit, or the GPU. The GPU determines whether you can play a game with all the fancy visual effects turned on, how high you can set the screen resolution, and how many frames (the images you see… Read more »
An introduction to spectroscopy: Applications from astronomy to art
Astronomers have a favorite saying that if a picture is worth a thousand words, then a spectrum is worth a thousand pictures. A spectrum is measured by the scientific technique known as spectroscopy, and unless you’re already familiar with the term, this may compel you to ask: what is spectroscopy? The short answer is that… Read more »
Roots of the Langlands Program
The Langlands Program has been progressing for a long time, with many of the big names in mathematics involved. Dr. Matthias Strauch, an Associate Professor in the Indiana University Mathematics Department, and I discussed some of the history of the field. The story begins with linear equations, although the modern scope of research has flown… Read more »
Ordering disordered materials
When we look around the world, we see order and symmetry. It’s evident in snowflakes, flowers, and beehives, just to name a few. Going beyond what the plain eye can see, we also know that several chemical structures consist of ordered atoms. For example, think of sodium chloride (more plainly known as table salt). Its… Read more »
Makerspaces and their growing role in STEM education
As a young child, years before the first Harry Potter book was published, I sat at my mother’s kitchen table mixing together anything I could find into a tall glass and calling it a potion. Now, this was just pure imagination and I’m sure that none of my concoctions were palatable, possibly even so bad… Read more »
Heritability: what it means and why it’s important
In a previous post, I briefly discussed something called genetic correlation and how this might be important for the evolution of a trait. Now, I hope to further clarify that concept and add to that a discussion of a very important concept in evolutionary biology—heritability—and tie it back to my initial discussion of the evolution… Read more »
