We finally learn the rule of quantum mechanics responsible for a lot of the strangeness of the theory.

This video provides an explanation of what diffusion is, how it occurs, and how to change the rate of diffusion. The concept of diffusion is demonstrated through the example of a plate of food emitting a smell that travels across a room....

The proof and maths of Noethers theorem: There are two ways to approach Noethers theorem that I know of. The most common is through Lagrangian mechanics- where the proof is surprisingly simple but unfortunately quite opaque . The other...

Well be looking at Bells Theorem and what it actually says about whether Quantum Mechanics is true.

Derivation for the impulse and momentum formula for a system of particles. Notice that if the sum of external forces = 0 then momentum in the system is conserved!

Conservation of Momentum example 1

If you're given the parametric equations describing the path of a particle. How do you find out the accelerations in the normal and tangential direction? Find the velocity and you know the tangential direction. Find the acceleration and...

This video is a lecture presentation on how to calculate the density of a substance. The presenter explains how density is the property of a substance that defines how massive that substance is per unit volume. The video shows examples...

What are the three ways of measuring sand clouds? When measuring a sand cloud, what key points do scientists determine?<br/>

Contextuality might mean that there are no alternatives to Quantum mechanics that are sensible. Given Quantum isnt sensible either, there may just not be any sensible theories at all.

Water in the Air reveals the varied phases of water that surround us, fall on us, travel in air, and serve as a crucial component of the water cycle. Emphasis is on the fact that water in air can be vapor or solid, visible or invisible,...

These second-order linear differential equations can be written in the form

dx/dt = ax +
by
dy/dt =
cx + dy
Depending on the values of a,b,c and d, the dynamics will be very different! They can be...
