Dig into Noam Chomsky’s theory of universal grammar and decide: are there universal grammar rules and are they hardwired into our brains?

Uploaded 29-06-20

--

Language is endlessly variable. Each of us can come up with an infinite number of sentences in our native language, and we’re able to do so from an early age— almost as soon as we start to communicate in sentences. How is this possible? In the early 1950s, Noam Chomsky proposed a theory that the key to this versatility was grammar. Cameron Morin details Chomsky's theory of universal grammar.

Lesson by Cameron Morin, directed by Eoin Duffy.

(Filmed at TEDxPSU.)

Why do we call women ladies? Well, etymologically-speaking, the word comes from the Old English words for hlaf (bread) and daege (maid), which, combined, mean the female head of the household and eventually indicated high social standing. Jessica Oreck and Rachael Teel follow the word to its contemporary position simply describing a female.

Explore the sustainability of fossil fuels, nuclear power, and renewable energy and how much space each of these power sources use.

No matter how we make electricity, it takes up space. Coal requires mines, and plants to convert it into electricity. Nuclear power takes uranium mines, facilities to refine it, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels. So how much space would it take to power the whole world? Explore the sustainability of different power sources.
