Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completelyoff the grid, but even at the loneliest corners of the world, electric...
As it spins, the generator uses the kinetic energy from the turbine to make electricity. Electricity cables: The electricity travels out of the generator to a transformer nearby. Step-up transformer: Electricity loses some of its energy as it travels down wire cables, but high-voltage ...
Why do they use such high voltages? To explain that, we need to know a little about how electricity travels.As electricity flows down a metal wire, the electrons that carry its energy jiggle through the metal structure, bashing and crashing about and generally wasting energy like unruly school...

Of course, using a generator to make electricity is just the beginning. After you get your electrons moving along, you'll need an electrical circuit to do anything with it. Find out why next.Electrical Circuits Batteries When you load a battery into an electronic device, you're not simpl...
You have mentioned numerous times that we should restrain artificial intelligence, but it’s much harder to restrain humans. What do you think we can do to restrain the large internet companies?" 创新工场CEO李开复(问): 互联网巨头拥有巨量的数据,而这些数据会给他们各种以用户隐私和利益换取暴利的...
That was all it took to make me an artist. W: How do you describe your work? M: My work speaks to the five-year-olds in all of us that we become experienced when we grow up. We’re always five years old at heart. We all want to have fun. W: That’s a unique idea, which...
To what extent do you agree or disagree? Some people think that robots are very important for humans' future development. Others, however, think that robots are a dangerous invention that could have negative effects on society. Discuss both views and give your opinion. Some people claim that ...
In turn, ecological behaviour is defined as behaviour that directly (e.g., saving electricity in one’s home) or indirectly (e.g., supporting campaigns that promote renewable energy) contributes to changing humans’ impact on the natural environment and raises awareness of environmental issues (e...
There are many reasons why people use humidifiers, from relieving sinus congestion to creating a more habitable environment for tropical plants. Butwhat does a humidifier do, exactly? One thing that makes winter uncomfortable for humans, even inside a nice warm building, is low humidity. People ...
