How does evolution really work? Actually, not how some of our common evolutionary metaphors would have us believe. For instance, it's species, not individual organisms, that adapt to produce evolution, and genes don't "want" to be passed on -- a gene can't want anything at all! Alex Gendler sets the record straight on the finer points of evolution. [Directed by Giant Animation Studios, narrated by Julianna Zarzycki].

The ratio of a circle's circumference to its diameter is always the same: 3.14159... and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we'll never figure out its exact value no matter how close we seem to get. Reynaldo Lopes explains pi's vast applications to the study of music, financial models, and even the density of the universe. [Directed by Igor Coric, narrated by Addison Anderson].

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.

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].
