We are well over the one-year mark on the global COVID-19 pandemic. Progress is uneven. The U.S., for example, spent much of the last year at war with itself over basic scientific common sense. Instead of embracing cost-effective protocols like masking and social distancing, right-wing elements of the U.S. chose […]

Since Wednesday, I, like most Americans, have been trying to make sense of the events of that day. I find it’s usually best to begin with the facts, so that’s where I will start this reflection. Wednesday was to be devoted to proposal writing. After reading the newspaper, then eating […]
Over the winter break, I have picked up my little muon detector data side project that started in the spring term of 2020. A few days ago, I remarked on how I wanted to take account of “weather” in the data – variations around a daily expectation given seasonal conditions […]
I am spending some time playing around with the cosmic ray muon data from an instrument in the SMU Physics Department. That instrument is located in the basement hallway of Fondren Science Building. I already setup a “dashboard” of information derived from the instrument, available here: https://blog.smu.edu/saso/projects/muon-observatory/. If you want […]
With reports from Pfizer/BioNTech and Moderna that the preliminary analysis of their data suggests a 95% effective vaccine (one each for each company) [1], I found myself wondering about the mathematics of vaccine effectiveness. There were some small details about how numbers were calculated from the data that were lost […]
There are a lot of idiots on social media. This will come as no surprise to most of you (to the rest … well, chalk up one more). For example, in response to the COVID Tracking Project’s update of weekly COVID-19 infection, hospitalization, and death data, this was posted: Of […]
The Biden transition team has been hard at work preparing for the first real presidency in 4 years. While there will be a lot of work to do to claw out of the abyss created by the previous 4 years of chaos, mismanagement, and willful ignorance of reality, it’s nevertheless […]
In my thoughts on the close of the experiment with American Fascism, I worried at the end about the damage that would be wrought in the months before Trump is constitutionally required to leave office. Here is a good example on the scientific side of things: www.washingtonpost.com/weather/2020/11/09/trump-removes-climate-program-director/ UPDATE: 10:46am This […]
On Saturday, we took a break from the pandemic to go outside and look for a comet. We live in a Dallas suburb, but one which has grown a lot in 10 years. The skies are not quite as dark as they used to be, but we thought it might […]
It has been 73 days since Texas, racing to reopen without first putting in place large-scale testing and tracing infrastructure, ceded the population of the state to the SARS-CoV-2 virus. That was COVID Day, or C-Day: May 1, 2020. On C-Day, Texas announced that businesses could re-open at 25% capacity; […]
This is the second day in a row that Collin County, TX, has not reported or updated its COVID-19 case or death count (or any other statistics). It is – likely not coincidentally – two days since the State took over the handling of cases from the County. The question […]
In 1970, Hall, Lind, and Ristenen (Univ. of Colorado at Boulder) published a paper in the American Journal of Physics (AJP, vol. 38, No. 10) on “A Simplified Muon Lifetime Experiment for the Instructional Laboratory.” Basically, it articulates precisely the experiment at the heart of a similar instrument at SMU.
