Unicorn Meteor Shower Tonight!
The Physics of a meteor Shower We’ve all seen a meteor shower, but do you understand the physics behind it? A giant rock hurdling through space? Nope. It’s actually dust burning up in the atmosphere. Most meteors are no larger than a grain of rice. The most interesting thing about a meteor shower is that the meteors are mostly stationary relative to the sun. It’s a cloud of dust that sits at the same spot … Continue reading Unicorn Meteor Shower Tonight!
Stephen Hawking’s Ph.D. Thesis Crashes Cambridge Site After It’s Posted Online
Interest in “Properties of Expanding Universes” is at an all-time high: Stephen Hawking’s doctoral thesis of that name crashed Cambridge University’s open-access repository on the first day the document was posted online. The Cambridge Library made several PDF files of the thesis available for download from its website, from what it called a high-resolution “72 Mb” file to a digitized version that is less than half that file size. A “reduced” version was offered that … Continue reading Stephen Hawking’s Ph.D. Thesis Crashes Cambridge Site After It’s Posted Online
Scientists detect gravitational waves from a new kind of nova, sparking a new era in astronomy
Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe. On Aug. 17, those signals reached Earth — and sparked an astronomy revolution. The distant collision created a “kilonova,” an astronomical marvel that scientists have never seen before. It was the first cosmic event … Continue reading Scientists detect gravitational waves from a new kind of nova, sparking a new era in astronomy

How to manage studying for math with ADHD
We get a lot of students with ADHD that struggle with studying for mathematics. I’d like to take some time to share some tricks and techniques for managing this learning difference and using it to your advantage. I have a particular insight into this subject because I have ADHD and managed to survive all the way through an M.S. in physics. It took me a long time to figure out what works, for me it … Continue reading How to manage studying for math with ADHD
