🔬#MESExperiments 54: SpillNot Centripetal Tray https://3speak.tv/watch?v=mes/863a9706 & https://youtu.be/eeQXcD3j4kE

In this experiment I showcase the amazing SpillNot centripetal waiter's tray, whose circular motion can balance a cup of water without spilling it over, even while performing a full 360 degrees upside down! The SpillNot works on the principle that circular motion involves a centripetal force that brings the tray back towards the centre of the circular motion — this results in the cup of water experiencing a normal force far directly onto the tray, which far exceeds the downwards force due to gravity. The most astonishing part is that even a straw placed in the cup barely even experiences any slight nudge as it moves at rapid speeds. I also place my phone in the tray with both front selfie camera and rear camera views to further illustrate this amazing phenomenon!

Motion in Space: Velocity and Acceleration https://3speak.tv/watch?v=mes/e443f9d3 & https://youtu.be/c9wE-BMvaY4

In this video, I go over further into vector functions, and this time look at motion in space in terms of the velocity, acceleration, and position of objects moving in 2D or 3D space. Using the fact that the rate of change of the position of an object is the velocity, and likewise that the rate of change of velocity is the acceleration, I show we can write the velocity and acceleration of an object just in terms of the derivatives of the position vector. Likewise, going backwards via vector integrals, we can obtain the velocity from the acceleration vector, and the position from the velocity vector.

Spherical Harmonics: Atomic Orbitals, Laplacian in Polar and Spherical Coordinates, Laplace Equation https://3speak.tv/watch?v=mes/220d6572 and https://youtu.be/p5SdobFPiKY

In this video, I go over a deep dive into the famous spherical harmonics, which are the solutions to Laplace’s equation in spherical coordinates and are very prevalent in physics, especially in the quantized configurations of atomic orbitals or the electron charge distribution around the atom's nucleus.

🔬#MESExperiments 53: Synchronization of 32 Metronomes https://3speak.tv/watch?v=mes/718150d8 and https://youtu.be/a7Nwrt3O1JQ

In this video I have uploaded the famous synchronization of 32 metronomes experiment from the Ikeguchi Laboratory in Japan on September 14, 2012.

Vector Functions: Arc Length and Curvature https://youtu.be/i9ForOVH5Bk

In this video, I go over further into vector functions and this time do a deep dive into the arc length and curvature of a space curve. I also go over normal, binormal vectors, as well as the TNB frame, normal & osculating planes, and much more, so buckle up!

🔬#MESExperiments 52: Magnets in Repulsion Bridge Drop Tests https://youtu.be/ZhrCJXM9DP4

In this experiment I drop magnets in repulsion vs a nonmagnet from a bridge of about 29 feet high, and got similar drop times for both with no significant difference. I did 10 drop tests while alternating hands to mitigate any inherent bias and still got similar times.
