Fear not! Physics content returns in mid-August. In the meantime, join us for an evening walk along Playa las Bachas on Santa Cruz Island in the Galápagos. White sand, calm water, and a peaceful sunset at one of the most serene beaches in the islands. Check out the video below!

This summer, while educational content lies essentially dormant in the USA, I have been thinking about posting videos from my family's recent trip to the Galápagos Islands. I have made 5 so far and have roughly 20 more to make, all filmed with my new GoPro Max 2 360 degree camera. They are currently unlisted but available in a playlist on my YouTube channel. The question is: will posting roughly 25 non-physics videos confuse my audience? I genuinely want your opinion on this one. Check out the video below!
This one has nothing to do with physics! I have been applying to Survivor annually since I was 39, and this year I submitted an open call audition video. I am 53, I am from Ann Arbor, I have been married to Kate for 25 years, and I look like Ozzy and Rupert had a kid together. Put me on Survivor, please! Check out the video below! In this new lesson, Bobby, Billy, Bo and I explore the capacitance of a parallel-plate capacitor, including what happens when a dielectric is inserted between the plates. We work through why adding a dielectric to an electrically isolated capacitor decreases the electric field and electric potential difference between the plates, and therefore increases the capacitance. We also revisit an important idea: capacitance depends only on the physical properties of the capacitor, not on the charge stored or the electric potential difference. 
The natural length of a spring is the length of the spring with no forces acting on it. In this short demonstration, I use a vertically hanging spring to show exactly what that means, measure the displacement from equilibrium when a mass is added, and explain why so many students struggle with this concept.

This one has nothing to do with physics! My daughter Ryan, who you may remember from several Flipping Physics videos, is a photography major at Rhode Island School of Design and a tattoo apprentice in Los Angeles. If you are in the Venice Beach area between mid-June and early August, you might be able to get a tattoo from her at a reduced price. She can design one for you or you can pick from her flash sheet designs. Even if you cannot make it to LA, you can support her by following her on Instagram or TikTok. Check out the video below!
Torricelli's Theorem says the speed of a fluid flowing out of a small spigot from a large reservoir equals the square root of 2 times the gravitational field strength times the vertical height of the fluid above the spigot. In this video, I use a rain barrel to demonstrate it in action, predicting exactly where the water will land using projectile motion, and placing a rubber ducky right on that spot. Check out the video below!
This one is for all of my late testing AP Physics students. Whether you missed your exam due to a snow day in Denver or for any other reason, I see you and I did not forget about you. Get a good night's sleep, eat well, stay hydrated, bring a straight edge, and bring mass to the party. It has been a long year, longer for you. I am proud of you. Go do your best!
In this new lesson, Bobby, Billy, Bo and I explore equipotential surfaces in a uniform electric field. We connect what we already know about uniform electric fields, conductors in electrostatic equilibrium, and electric potential to build a deeper understanding before moving on to parallel-plate capacitors. We also discuss why it takes zero work to move a charge at a constant speed along an equipotential surface and why that requires constant speed rather than constant velocity.  |

Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class. Archives
