Try to sing the impossible note! Singers try to sing into a pipe, and find certain notes are impossible to sing, even for professionals. WHY?! If you'd like to support Dianna during her recovery, you can do so here → https://www.patreon.com/physicsgirl This edition of the Physics Girl Everyday Mysteries series is a physics experiment uses a quirk of the voice and your vocal cords. Try it at home! Prof Joe Wolfe’s acoustics website: http://newt.phys.unsw.edu.au/music/ Intro chapter on the voice: http://www.animations.physics.unsw.ed... Wade et al paper on soprano singing through resonances: https://asa.scitation.org/doi/abs/10.... More on vocal tract resonances: http://newt.phys.unsw.edu.au/jw/sopra... https://www.ncbi.nlm.nih.gov/pubmed/1... More facts: Most objects have a number of different resonant frequencies. The first resonance of the pipe were were using was around 70 Hz, which was lower than any of us could sing. A bass singer could hit that note, but were were singing in the range of the second and third resonances of the pipe. No longer compiling your pipe singing submissions, but feel free to tweet me your attempts! @thephysicsgirl http://physicsgirl.org/ http://twitter.com/thephysicsgirl http://facebook.com/thephysicsgirl http://instagram.com/thephysicsgirl Creator: Dianna Cowern Editor: Levi Butner Research: Imogen Ashford #ResonantFrequency #naturalfrequency #notesinging #impossiblesinging #impossiblenote #physics #frequency #audio #PhysicsGirl

Thank you Independence Science for printing such wonderful t-shirts for the New Jersey Abacus Bee. We can’t wait to don them this Saturday!

The vibrant colors and tactile abacus beads are a perfect match for what promises to be an exciting day of friendly math competition and STEAM fun!
