Video Summary
Once upon a time, in a math land so grand that nine canaries found themselves perched on wires over sand. Many say it was all planned - just a device to represent equivalent fractions for kids all over the world to see. Who knows?

Each wire held a fraction, or a piece of the pie, Three ninths, one third— oh not in my eye!
“Listen up,” said the canaries, feathers all a-fluff, “Equivalent fractions, that’s some sick stuff!” 🎵

Thank you for watching Numberock's Equivalent Fractions Song.

A song to help kids learn about fractions (numerators, denominators, improper fractions, you know, the good stuff).

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

Check out some beautiful music made from space itself
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub

There is no sound in space. In the near-vacuum of space, there is nothing to transmit the physical waves that we need to perceive sound. But that doesn't mean we can't MAKE sound from space. This week, I feature several artists using scientific data to create "space sonification" projects. From the longest palindrome ever created to a chorus created from Earth's magnetic field, these pieces lie at the intersection of art and science. More than just art, they allow us to perceive patterns in complex data in a completely new way
Perhaps it answers the question: If the universe had a voice, what song would it sing?

Why does sex exist? You might think the obvious answer is “reproduction” but there are plenty of organisms on Earth that don’t require sex to reproduce. And the more that scientists examined sex, they more they realized that it’s an expensive and inefficient way to get your genes to the next generation. The true purpose of sex is actually one of the longest-standing mysteries in evolutionary biology. But scientists are closer than ever to finding the answer. Here’s what we know about the evolutionary enigma of sex.

Pucker up. I'm gonna lay some science on you!

When you really think about it, kissing is an odd human behavior. You know, all the rubbing of our faces all over each other. So there must be a good reason why we do it, right? From motherly comforts to testing the genetic compatibility of your "mate", the science of kissing is pretty awesome.

Learn more about "The Science of Kissing" by Sheril Kirshenbaum at http://amzn.to/Nuy0TE

Sheril's book has an extensive bibliography if you'd like to look more closely at any of these studies, but here's a couple that I mentioned:

Study of facial features and attractiveness ("men prefer fuller, redder lips"): http://psycnet.apa.org/journals/psp/68/2/261/

Claus Wedekind's famous "t-shirt" study: http://www.ncbi.nlm.nih.gov/pubmed/7630893

Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control themselves. This week we look at all these questions and more.

In a world of distractions, how do we pay attention?

It seems like every week someone tells us how the internet and the digital age are overloading our brains. Sure, sometimes it feels like we're being fed more information than we can handle, that we're paying attention to the wrong things. Are we giving our brain a fair shot?

I explore some science that show how paying attention can be a bad thing, and then some science about how paying attention can be a very helpful thing
Special cameos by Hank Green and Mike Rugnetta!
