A new video was added to Ivy Gorgon's playlist, Biological sex science. “Learning that I was intersex was just absolutely mind-blowing.” #Shorts Mimi was born a little different and she spent years hiding it. But a chance discovery at 21 changed her life for the better. Intersex is an umbrella term for over 30 different chromosomal variations. Variations are a natural biological event, estimated to happen in about 17 in every 1,000 live births.

“Waves are energy in motion. They carry momentum and information through the universe. They are all around us. Light waves, ocean waves, sound waves, and many others. Sound waves are pressure waves caused by a physical interaction. They move through matter. And in doing so, cause it to vibrate. In this experiment, two techniques are used to visualize sound waves: Water resting in a low-frequency speaker and salt resting on a high-frequency mechanical wave driver. As the instruments are activated they vibrate in resonance with the wave form, revealing geometric patterns. The patterns change with the pitch and volume of the sound wave, visualizing the nature and shape of wave forms.”

The Emu in the Sky

If you look up into the sky tonight, you can still spot the Emu in the Sky. You’ve almost certainly been looking at it all your life, but you’ve probably never seen it. The Emu is stretched across one of the most familiar objects in the night sky, the Milky Way.
