Yale faculty member Claire Bowern explains the evolution of the English language in this animated TED-Ed video.
Enjoy!
When we talk about ‘English’, we often think of it as a single language. But what do the dialects spoken in dozens of countries around the world have in common with each other, or with the writings of Chaucer? Claire Bowern traces the language from the present day back to its ancient roots, showing how English has evolved through generations of speakers.

A simple explanation on why we only see one side of the Moon from Earth.
Enjoy!
Only one side of the Moon is visible from Earth because the Moon rotates about its spin axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases. The unilluminated portions of the Moon can sometimes be dimly seen as a result of earthshine, which is sunlight reflected off the surface of the Earth and onto the Moon. Since the Moon’s orbit is both somewhat elliptical, and inclined to its equatorial plane, librations allow up to 59% of the Moon’s surface to be viewed from Earth (but only half at any instant from any point).
