Image credit: NASA/JPL-Caltech/ESA/Institute of Astrophysics of Andalusia, University of Basque Country/JHU By Stacy Palen I was poking around, looking for something completely different when I came across this nice little vignette from "Physics Today" published in 20061. It’s the story of the discovery of dark matter, told by Vera Rubin... Continue reading
Most elementary schools in the US no longer teach cursive writing, and many educators, psychologists, and others have lamented the change. Philadelphia-based health and science writer Markham Heid summarizes some of the research showing the benefits of longhand writing and adds an argument of his own in this September 2019 essay in elemental+, a Medium blog. Markham Heid–"Bring back handwriting: It's good for your brain"–elemental+, 12 September 2019 Heid’s argument is stated very clearly in the title of his essay. What advantages does he say handwriting offers? Summarize them. Which of the advantages do you find most persuasive? Why? Explain... Continue reading

By Stacy Palen I long ago stopped keeping track of the number of moons around Saturn and Jupiter. It often feels like there is a contest going on among astronomers—who can find the most moons around “their” planet! In early October, a report hit the news of 20 new moons... Continue reading
The NCAA is in the news again, and it’s not even March or bowl season. What’s going on? A new law in California gives student athletes the right to be paid for the use of their names and images, and the NCAA is strongly opposed to it. Veteran journalist and LA Times editorial writer Scott Martelle has a few things to say about the controversy in this October 2019 column. Scott Martelle, "NCAA's response to California: Don't stop our exploitation" Martelle makes it clear from the very beginning that he opposes the NCAA’s objection to California’s new law allowing college...

We already know this. People spend a lot of time—maybe too much—on their phones and other devices, and it’s a troubling trend. But who is ultimately responsible for changing the habits and fixing the problem? Does the responsibility lie squarely with individual users to make changes? Should designers and developers of apps and devices make modifications to their products to make them less addictive? Both? Neither? San Francisco-based New York Times writer Nellie Bowles explores these questions in this October 2019 article. Nellie Bowles, "Addicted to screens? That's really a you problem" Bowles’s essay about screen addiction focuses on the... Continue reading

Credit: NASA/Bill Ingalls By Stacy Palen In July 2019, I received a few queries about a “black supermoon.” Since I had no idea what that was, I decided to track it down. It comes from a group of click-bait articles like this one, which are apparently taking off from a... Continue reading

What if your very life depended on trusting people that you had learned explicitly to hate, feat, and distrust? Yikes! What a terrible question, right? You may not be able to answer it easily, but most likely you will never find yourself in such a dramatic situation, so no worries. Writer and former publisher of the Jewish Journal Rob Eshman talked with someone who did face that question, and he writes about their conversation in this October 2019 Los Angeles Times essay. Eshman, “The Yom Kippur lesson I learned from a Muslim man” Early on in his essay, Eshman mentions... Continue reading

B.O'Kane / Alamy Stock Photo By Stacy Palen This week in Physics Seminar, we had a psychologist come and talk to us about a number of studies that indicate how stereotypes impact the performance of underrepresented groups. Generally, this refers to women and minorities (although other categories also intersect). The... Continue reading

By Stacy Palen I teach at an open-enrollment university with a very large number of non-traditional students: nearly all of my students have jobs with large time commitments. Many of them are parents of young children. More than half of them are married. This semester, something interesting has been happening... Continue reading

By Stacy Palen It’s that time of the semester when we are talking about galaxies, galactic structure, and supermassive black holes. Fortunately, Chandra has our back and has released a new image of a superbubble in NGC3079. The picture is sufficiently spectacular that I want to let you know about... Continue reading

By Stacy Palen Credit: Sloan Digital Sky Survey, www.sdss.org Once in a while something new happens. In the case of an article published in The Atlantic, astronomers observed an object that had properties like those of a supernova explosion, but much too fast. That led to some detective work across... Continue reading
