All of modern society relies upon a seemingly simple but surprisingly complex unit of measurement: the second. But knowing exactly what a “second” is is more complicated than you might think!

Hurricanes, typhoons, and tropical cyclones are Earth’s most powerful storms, capable of unleashing destruction and death on coastal areas worldwide. As climate change warms Earth’s oceans, we face more risk of storms rapidly intensifying into category 5, sometimes in less than a single day. Being able to predict these rapidly intensifying storms will save lives, but studying hurricanes in detail is difficult and dangerous. So in order to improve our understanding of hurricanes, scientists have built a machine that can create hurricane conditions indoors. #weather #hurricanes

News about climate change is often full of doom, guilt, and anxiety. This can make many people reluctant to pay attention to or discuss it. We asked former Vice President Al Gore to help us find a different way to talk about climate change.

Why is the universe organized the way it is? And why is it so empty? From planets and stars to superclusters and galactic filaments, the universe’s largest structures formed because of its smallest. In this special collaboration with PHD Comics, we’ll learn how the earliest, quantumest blips seeded the structure of everything everywhere.

Butterfly metamorphosis is still a bit of a mystery. What happens inside a chrysalis to turn a caterpillar into a beautifully painted butterfly? Does it really turn to soup? I visited Dr. Arnaud Martin, who uses the CRISPR genetic modification technology to learn about how genes build bodies. Dr. Martin uses CRISPR to disrupt certain genes, and then looks for changes in butterfly wing patterns, creating designs we never see in nature. This tells us which genes control which part of the "wing painting" process. In the process of visiting Dr. Martin’s lab, I had my mind blown about what REALLY happens during butterfly metamorphosis. You will too. #butterflies #CRISPR #genetics

Otters are more than just cute, adorable little fuzzballs, they are one of the greatest conservation success stories of all time. Sea otters are a keystone species, meaning that an entire ecosystem depends on their presence. After they were nearly hunted to extinction for their dense fur, sea urchins (the otters' favorite food) nearly destroyed the Pacific kelp forests, a habitat that hundreds of species rely on for food and shelter.
Thanks to the hard work of conservation scientists at places like the Monterey Bay Aquarium, sea otter populations are on their way back. Here's the story of one orphaned sea otter pup's journey back to the wild

Lyrics:
Any whole with equal sized parts
Like a pie, brownies, or a chart
Can be split into fractions to help you find
The parts that you want and the parts you left behind
Whether it’s made of shapes or numbers
There’s a number on top and a number under
1 whole, 1 half, 1 third,
1 fourth, or a quarter, whatever’s preferred
1 fifth, 1 sixth, 1 seventh,
1 eighth, 1 ninth, 1 tenth, 1 eleventh
Twelfths: “Um, hey! What about me?”
And 1 twelfth
The denominator is down
It tells the total number of pieces around
Then the numerator calls out
The number of parts that you’re talkin’ about
2 wholes, 2 halves, 2 thirds,
2 fourths, or quarters, whatever’s preferred
2 fifths, 2 sixths, 2 sevenths,
2 eighths, 2 ninths, 2 tenths, and 2 elevenths
Twelfths: “Yea, I’m… still here.”
And as high as you want to go!
The denominator is down
It tells the total number of pieces around
Then the numerator calls out
The number of parts that you’re talking about
3 wholes, 3 halves, 3 thirds,
3 fourths, or quarters, whatever’s preferred
3 fifths, 3 sixths, 3 sevenths,
3 eighths, 3 ninths, 3 tenths, and 3 elevenths
Everyone:
And 3 twelfths

What are fractions? You will learn how fractions are a way of writing the part or parts of something. All fractions have a numerator and a denominator. Parts that are the same size and shape are called congruent parts.

Can you take a derivative only partway? Is there any meaning to a "half-derivative"? Does such a concept even make sense? And if so, what do these fractional derivatives look like?

===============================
Minor correction: The footnote at 7:34 should say the trig substitution produces another *whole* factor of pi (not a root pi) in the numerator which then cancels the *two* root(pi)'s that appear in the denominator from applying the half integral formula twice.
