What if We Replaced Nuclear With Potatoes

$Why Wolves Dont Chirp Check out Brilliant (and get 20% off) here: https://brilliant.org/MinuteEarth/ Sounds that animals make can be really different, and it turns out that theres a reason why some species communicate with certain sounds. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. To learn more, start your googling with these keywords: frequency - how often a wave occurs in a certain unit of time Hertz - a unit of frequency (Hz), the number of waves that occus in a second pitch - a perceptual property of sounds that allows their ordering on a frequency-related scale echolocation - the location of objects by reflected sound refraction - the change in direction of a wave diffraction - the bending of waves around obstacles and the spreading out of waves beyond openings Subscribe to MinuteEarth on YouTube: http://goo.gl/EpIDGd Support us on Patreon: https://goo.gl/ZVgLQZ And visit our website: https://www.minuteearth.com/ Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC And download our videos on itunes: https://goo.gl/sfwS6n Credits (and Twitter handles): Video Writer, Director, and Narrator: Kate Yoshida (@KateYoshida) Video Illustrator: Arcadi Garcia Rius (@garirius) With Contributions From: Henry Reich, Alex Reich, Ever Salazar, Peter Reich, David Goldenberg, Julián Gómez, Sarah Berman Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder Image and sound credits: Copes gray treefrog call Credit: U.S. Geological Survey Department of the Interior/USGS Google Earth photos Credit: Google, Maxar Technologies, Landsat/Copernicus Bottlenose dolphin whistles Credit: Centro Inderdisciplinare di Bioacustica e Richerche Ambientali, Università degli Studi di Pavia http://www-3.unipv.it/cibra/edu_dolphins_uk.html Humpback whale call Credit: NOAA and Northeast Passive Acoustics Research Group Koala call Credit: FreeSoundEffects.com Wolf howl sound - OrangeFreeSounds user Alexander http://www.orangefreesounds.com/wolf-howl-sound/ References: Arch, V.
