I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

Полезный урок для тренировки разговорного английского и произношения. Сначало читаете с английскими субтитрами, а потом без помощи субтитров. Упражнение не на понимание текса, а именно тренировка речи.

How the Brain Works These brief videos provide an introductory appreciation of how we learn skills and information, move, think, feel, speak and remember. They are brought to you by the UCLA Brain Research Institute and by Bruce H. Dobkin, MD, who directs the neurorehabilitation program in the Department of Neurology at UCLA. The videos especially aim to reach out to students in grade school to stir their interest, and to people with disabilities in walking, using an affected upper extremity, and loss of memory from neurological diseases such as stroke, brain trauma, tumors, multiple sclerosis, cerebral palsy, Parkinsons, and Alzheimers disease.

Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawn mowers.

Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion.

The Physics we're talking about today has saved your life! Whenever you walk across a bridge or lean on a building, Statics are at work. Statics is the study of objects when they're NOT accelerating. In this episode of Crash Course Physics, Shini talks to us about stretching, compressing, and springing as they relate to Statics! Also... Game of Thrones.

Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini talks to us about a particular mistake made in engineering the Millennium Bridge which allows us to talk about simple harmonic motion.

What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and what it all has to do with this thing called "Moment of Inertia."

Explore the lytic and lysogenic viral replication cycles with the Amoeba Sisters! This video also discusses virus structures and why a host is critical for viral reproduction. Expand details for table of contents and further reading suggestions! This updated video replaces our older virus video

Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know how far your window was off the ground. By using integrals, a tennis ball, and a stop watch, you can figure that out! It's all here in this episode of Crash Course Physics!

Who is the Easter Bunny?

Bei dem Osterfest geht es um die Kreuzigung von Jesus Christus und um seine Auferstehung von den Toten. Es ist ein religiöses Fest.

Talks about films with grammar revision and description learning

In this class we will discuss what sucessfull public speech is, you experience with it, evaluate speech of other persons. Also we will discuss grammar - usage of structures to express past habits and actions.

A couch is a sofa, such as people have in their sitting-rooms, often in front of the television. Some people spend a lot of time sitting on the couch watching television, and probably getting fat for want of exercise. We have a name for such people in English – couch potatoes. And, as British people are well known for watching TV a lot, perhaps we are a nation of couch potatoes. Google, the company that runs the internet search engine, has just published a survey which claims that British people now spend more time on the internet than they do watching television – 164 minutes a day on average on the internet, 148 minutes watching television.
