Erez Lieberman Aiden and Jean-Baptiste Michel show us how it works, and a few of the surprising things we can learn from 500 billion words. (Filmed at TEDxBoston.)

Like an actor's script, a sheet of music instructs a musician on what to play (the pitch) and when to play it (the rhythm). Sheet music may look complicated, but once you've gotten the hang of a few simple elements like notes, bars and clefs, you're ready to rock. Tim Hansen hits the instrumental basics you need to read music. [Directed by Thomas Parrinello, narrated by Tim Hansen].

Imagine you're fast asleep and then suddenly awake. You want to move but can't, as if someone is sitting on your chest. And you can't even scream! This is sleep paralysis, a creepy but common phenomenon caused by an overlap in REM sleep and waking stages. Ami Angelowicz describes just how pervasive (but harmless) it is and introduces a cast of characters from sleep paralysis around the world.

One of the most significant scientific discoveries of the early 21st century is surely the Higgs boson, but the boson and the Higgs Field that allows for that magic particle are extremely difficult to grasp. Don Lincoln outlines an analogy that all of us can appreciate, starring a large dinner party, a raucous group of physicists, and Peter Higgs himself.

You might have felt it -- the feeling that you've experienced something before, but, in reality, the experience is brand new. There are over 40 theories that attempt to explain the phenomenon of déjà vu. Michael Molina explains how neuroimaging and cognitive psychology have narrowed down the theories that could explain that feeling you're having...again.

Have you noticed how the full moon looks bigger on the horizon than high overhead? Actually, the two images are exactly the same size -- so why do we perceive them differently? Scientists aren't sure, but there are plenty of intriguing theories. Andrew Vanden Heuvel unravels the details of focus, distance and proportion that contribute to this mystifying optical illusion.

Is love a signal winding through your neural pathways? A cliche? A cult? Love is easy to compare but difficult to define, maybe because we're fundamentally biased; we try to define love while falling in or out of it. And love feels differently to every person who feels it, but this subjective emotion has evolutionary explanations, too. Brad Troeger takes a shot at the definition of love. [Directed by STK Films, narrated by Addison Anderson].

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Lucianne Walkowicz shows us the waves we can't see.

Traveling is extremely arduous for microscopic sperm -- think of a human trying to swim in a pool made of...other humans. We can compare the journey of a sperm to that of a sperm whale by calculating the Reynolds number, a prediction of how fluid will behave, often fluctuating due to size of the swimmer. Aatish Bhatia explores the great (albeit tiny) sperm's journey. [Directed by Brad Purnell, narrated by Addison Anderson].

What do Game of Thrones' Dothraki, Avatar's Na'vi, Star Trek's Klingon and LOTR's Elvish have in common? They are all fantasy constructed languages, or conlangs. Conlangs have all the delicious complexities of real languages: a high volume of words, grammar rules, and room for messiness and evolution. John McWhorter explains why these invented languages captivate fans long past the rolling credits. [Directed by Joyce Stenneke, narrated by John McWhorter].

The Japanese dance and theater art of kabuki, derived from the word kabuku, meaning "out of the ordinary," can be traced back to the streets of seventeenth-century Kyoto. Kabuki became a dramatic art for the common people, with its use of makeup and facial expressions rather than masks, as well as a playful take on current events. Amanda Mattes tracks the evolution of kabuki and its place in Japan's rich cultural heritage. [Directed by Tom Gran, narrated by Addison Anderson].

The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus -- that particularly perplex scientists. George Zaidan and Charles Morton show how to make an educated guess of where those itty-bitty freewheeling electrons might be. [Directed by Karrot Animation, narrated by George Zaidan].

Everyone hates mosquitos. Besides the annoying buzzing and biting, mosquito-borne diseases like malaria kill over a million people each year (plus horses, dogs and cats). And over the past 100 million years, they've gotten good at their job -- sucking up to three times their weight in blood, totally undetected. So shouldn't we just get rid of them?

The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that it's expanding constantly, so that all stars will eventually burn out into a cold nothingness. Renée Hlozek expands on the beauty of this dark ending. [Directed by Giant Animation Studios, narrated by Renée Hlozek].
