    (fun with Lagrangians) Cylinders with the same mass but different moments of inertia will roll down a flat surface at different accelerations, as they have to "convert" different amounts of potential energy into kinetic energy to achieve a given angular velocity.

    (199) A (continuous) wavelet transform is given by the overlap integral of the signal s with the kernel (wavelet) w, where the kernel is both shifted and stretched, allowing to extract information at different scales.

    (198) Aliasing: If your sampling is not fine enough, the signal you recover can have some very weird shape. Ironically this animation suffer from aliasing, so some dots seem to be moving backwards 🤷‍♂️

    (197) You can create the illusion of movement by sliding a mask over an appropriately prepared image. How-to in the short thread below (1/5)

    Surprised it took me this long to hear about but check it out :)

    By the way, congratulations for you ! Which Physics book would you recommend for someone curious but not in the field? And something 'light' about relativity?

    (185) At the interface between a dielectric and a metal, Maxwell equations admit solutions in the form of oscillations along the surface that couple the electric field and the electrons in the metal (surface plasma polaritons).

    (184) Any pulse can be thought as the superposition of sinusoidals If all sinusoidals travel at the same speed, the pulse will propagate without changing shape. But if different frequencies travel at different speeds, the pulse will be distorted (dispersion).

    I love your They somehow make me very happy when I read them. Like reconnecting to the reasons I studied Physics in the first place such a long time ago 😊

    (183) The dynamics of a free rigid sphere can be surprisingly complicated. In fact, beside rotating around an axis, the sphere can also precede (i.e. the axis of rotation is itself rotating) and nutate (i.e. the axis of rotation oscillates back and forth).

    Hallo you can read it here: Thread by : "Moving all the old Physics factlects to the same hashtag to make easier to find them. As Twitter does not allow me to ed […]" Enjoy :) 🤖

    Why not creating a section on your website with a collection of all the ? Making them a must for all players will definitely get you an invitation to all the shows. 😏🤓

  16. Let me introduce you the by . One of the most fun and instructive moments on Twitter for me! This is an example of the interesting factlets you can find. Two coupled nonlinear (wow that's new this week) oscillator sinchronize in anti-fase! Huygens.

    Hey, you must be in that parallel universe too, . 'Cause you heard and are repeating: You can only repeat something from a parallel universe: if you share it, too.
