Lest We Forget the Pioneer: Ottokar Tumlirz and His Early Demo of the Coriolis Effect

Two years ago I wrote an article about The Myth of the Toilet Flush, comparing the angular rotation caused by the earth's rotation to the typical rotation in experiments with garden hoses that make it easy to observe the Coriolis effect. There are several orders of magnitude in difference, and the effect can only be … Continue reading Lest We Forget the Pioneer: Ottokar Tumlirz and His Early Demo of the Coriolis Effect

The Twisted Garden Hose and the Myth of the Toilet Flush

If you have wrapped your head around why and how the U-shaped tube in the flow meter (described in my previous post) is twisted by the Coriolis force - here is a video of a simple experiment brought to my attention by the author of the quoted article on gyroscope physics: You could also test it … Continue reading The Twisted Garden Hose and the Myth of the Toilet Flush

Intuition and the Magic of the Gyroscope – Reloaded

I am baffled by the fact that my article The Spinning Gyroscope and Intuition in Physics is the top article on this blog so far. So I believe I owe you, dear readers, an update. In the previous article I have summarized the textbook explanation, some more intuitive comments in Feynman's Physics Lectures, and a new … Continue reading Intuition and the Magic of the Gyroscope – Reloaded
