Blue Whale Songs
Scientists can’t seem to figure out why blue whales are singing at a deeper pitch.

Blue whales’ songs are hauntingly deep, filled with extraterrestrial vibratos, and utterly mysterious. Despite many [...]

My sweet physheads have completed lab activities for the fall Physics 53 course and are now finishing the last of the material for recitation and preparing for the final exam — my how time flies. For the lab on mechanical waves and sound in particular, many students choose to submit a short research blurb about [...]

As students study for their final exam today — I thought it appropriate to capture a Wordle moment from Dr. Evans’ Energy 1 notes. Words and equations used in this course represent powerful ideas which have driven progress in science and technology and have served as a foundation to understanding our world. When [...]

Physheads love to oscillate.
LoggerPro is a great piece of software from Vernier, which has very good curve fitting capabilities as you can see in this screen shot:

Archimedes was such an amazing scientist, perhaps the greatest of antiquity, it is always delightful to recall the Eureka tale and consider the application of Archimedes’ Principle to the plethora of boats which populate the waters around DUML.
Students tend to enjoy this lab and are frequently heard exclaiming Eureka!

One of the highlights of the DUML summer physics is our four hour cruise to Cape Lookout National Seashore. Weather permitting, we head out on the Susan Hudson, get dropped off about an hour later at the dock in the bay.
Students generally have a great time relaxing. This year the trip was planned for [...]

The first exam, fourth quiz, ninth chapter, second lab, second week, and a ton of learning and problem solving are behind us. The pace of the course is quite something … as you can see in this picture as Dr. Evans presents a lecture about collisions.
DUML students are very aware of the pace — [...]

The second official lab allows students to figure out a procedure for determining the work done by friction for a typical introductory mechanics situation; namely, carts with an attached “friction pad” accelerated up an inclined plane. Anytime we can get out of the book and work out the concepts in the real world, [...]

Big class, lots of work, fast pace, challenging material, … Physics during summer session has begun in earnest. We are now into the fourth day of class, and are working on problems from chapter 5. Here is a picture of from the first recitation session, a couple of days, a quiz, homework set and lab [...]

Communicating with Dr. Evans today –> massaging schedule for lecture, recitation and labs
Communicating with Tom (IT) today –> imaging the physics computers
Communicating with self today –> modifying and uploading lab info to network folder
Life begins to accelerate on the island as we all get ready for a great summer session. I love the freshness of [...]
