Unlock the secrets of creating animated fire particles using SubUV texture techniques. This video will teach you how to set up fire animation with controllable color variations and incorporate it into your scenes, intensifying the...

In this video, you will learn how to create materials for smoke particles using the Niagara system. Explore techniques for achieving realistic smoke effects that can be used in various scenarios, such as chimneys or environmental...

We've covered macrophages and dendritic cells, so let's move on to neutrophils. These are the most abundant white blood cells, and they act as the first line of defense in innate immunity. How do they form, and what do they do...

Conventional current and electron flow. In this video we briefly learn the difference between conventional current and electron flow. We learn how the electron was discovered and why battery terminals are positive and negative. What is...

On the divergence field In Gauss law The operator that works on a vector field.
<
br/>
A normal explanation of the divergence operator, is saying that it measures how much is flowing in or out in a given area. In this video we...

Particle physicist Nima Arkani-Hamed (Institute for Advanced Study) relates his belief that supersymmetry must exist at some energy scale.

Particle physicist Nima Arkani-Hamed (Institute for Advanced Study) describes how physicists knew that the Higgs boson had to be there before any experiment.

Nobel Laureate in Physics Roger Penrose (Oxford) describes how, according to Einstein's special relativity, massive and massless particles move with respect to the light cones of space-time.

Imperial College cosmologist Claudia de Rham describes her view of how reinterpreting Einstein's theory of gravity in terms of particle physics gives a more coherent and elegant picture of the forces of nature.

Cosmologist Justin Khoury (Penn) describes what many have described as "the worst failure of contemporary theoretical physics".

University of Chicago cosmologist Rocky Kolb describes the history of dark matter: how it was overlooked by most physicists for decades together with current hypotheses of what it might be and experiments to determine which one is valid.

University of Chicago cosmologist Rocky Kolb relates how he reacts very differently to dark matter than dark energy: dark matter he regards as an opportunity, while dark energy "drives him nuts".

Let's learn about the differences between asteroids, comets, and meteors!

Index theory is a method used to gain global information about a nonlinear differential equation. One powerful insight is that closed orbits (periodic solutions) must have at least one fixed point inside of the curve. In fact, for a...

These second-order nonlinear differential equations can be written in the form: dx/dt = f(x,y) dy/dt = g(x,y) Got a nonlinear differential equation? No problem, just linearize it! This method approximates the vector field as a linear...

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 characterized by finding the eigenvalues...

Here we show another way to graphically interpret first order ordinary differential equations (ODE's) in the form dx/dt = f(x). Rather than solve the differential equation by integrating, which is often impractical, it's useful to graph...

In this representation I discuss the main principles of quantum mechanics behind the quantum computer. and How to build a device that can manipulate the energy operator of the Schrodinger Equation for an electron to change its spin...

In today’s lesson, we’ll look at phrasal verbs from a grammatical perspective. You’ll learn about the syntactic features of phrasal verbs, particles as adverbs or prepositions, and the difference between phrasal verbs,...

How to use interrogative questions in Japanese to ask things like "what are you doing on the weekend"

The Aurora has fascinated and intrigued people for ages. It is a display of light in Earth’s magnetosphere caused by high energy particles arriving to the planet in the solar wind. The Aurora is seen in both hemispheres. In the northern...

This problem is about finding the force on a particle when you are given the equation for potential energy as a function of position.

This problem is about using conservation of energy to find the speed of a particle given a graph of its potential energy as a function of position.

This problem is about the relationship between frequency and radius for a charged particle moving in a circle in a constant magnetic field.
