Refraction and Snell’s law | Geometric optics | Physics | Khan Academy

In the last couple of videos we talked about reflection. And that’s just the idea of the light rays bouncing off of a surface. And if the surface is smooth, the incident angle is going to be the same thing as the reflected angle. We saw that before, and those angles are measured relative to […]

Organic Chemistry: 5 Must-Know Reactions of Benzene

Hi everyone this is Maverick Puah the Chemistry Guru now in this video we want to go through the 5 must-know reactions of benzene and 3 important reactions of methylbenzene now the first must-know reaction of benzene is the nitration of benzene to form nitrobenzene. So this reaction is done using concentrated HNO3 in concentrated […]

The non-common sense of quantum physics | Alberto Casas | TEDxMadrid

The non-common sense of quantum physics | Alberto Casas | TEDxMadrid

Translator: Reviewer: Denise RQ What is common sense? Common sense is the judgments that we make on things based on our own experience. The problem is that our experience is very limited and it encompasses a very reduced range of scales, more specifically, physical scales: distance scales, time scales, energy scales. And the mental models […]

Work/energy problem with friction | Work and energy | Physics | Khan Academy

Welcome back. Welcome back. Welcome back. I’ll now do another conservation of energy problem, and this time I’ll add another twist. So far, everything we’ve been doing, energy was conserved by the law of conservation. But that’s because all of the forces that were acting in these systems were conservative forces. And now I’ll introduce […]

If You Don’t Understand Quantum Physics, Try This!

If You Don’t Understand Quantum Physics, Try This!

Quantum physics has a mystique of being complicated and hard to understand, in fact Richard Feynmann who won the Nobel prize for his work on quantum electrodynamics said: “If you think you understand quantum physics, you don’t understand quantum physics”. Which is kind of disheartening for us because if he didn’t understand it, what chance […]

Electromagnetic waves and the electromagnetic spectrum | Physics | Khan Academy

– You might note that if you’ve got a positive charge sitting out in space it’s gonna create an Electric field, and that Electric field is gonna point radially outward away from the positive charge. And you might note that if you’ve got a current in a wire, that current is gonna create a Magnetic […]

Building An Artificial Intelligence

This video is brought to you in thanks to Squarespace. Whether you need a domain, website or online store – make it with Squarespace! In the last video in this series, we discussed the biologically inspired structure of deep learning neural networks and built-up an abstracted model based on that. We then went through the […]

What is Scientific Racism? | The History of Hate

Oh yeah, this one is gonna make me popular. So yeah, there was a time where racism was not only mainstream but scientifically approved. We had top scientists in their fields writing long diatribes about “race science” all of which turned out to be… well, racist conjecture. And while we put it in the realm […]

Neuromorphic Computing Is a Big Deal for A.I., But What Is It?

Neuromorphic Computing Is a Big Deal for A.I., But What Is It?

We often talk about how traditional computing is reaching its limit–there’s a threshold we can’t move past without making some seriously big changes to the way we structure computers. One of those exciting ways is by making physical computers a little more like human brains. We introduced this concept in more detail here, but a […]
