Can you solve the rogue submarine riddle? - Alex Rosenthal

Practice more problem-solving at https://brilliant.org/TedEd [https://brilliant.org/TedEd] -- Smuggling yourself aboard the rogue submarine was the easy part. Hacking into the nuclear missile launch override — a little harder. And you’ve got a problem: you don’t have the override code. You know you need the same numbers that were used to authorize the launch, but one wrong answer will lock you out. Can you figure out what numbers to enter to stop nuclear war? Alex Rosenthal shows how. Lesson by Alex Rosenthal, directed by Igor Coric, Artrake Studio. A very special thank you to Jon Schneider and Brian Chen, who wrote the original version of this puzzle for the 2021 MIT Mystery Hunt and were inestimably helpful in adapting it to this format.

Scientists are mesmerized by this lake - Nicola Storelli and Daniele Zanzi

Explore the depths of Lake Cadagno, a meromictic lake that is considered a model for Earth before the Great Oxidation Event. -- In the millions of years since oxygen began saturating Earth’s oceans and atmosphere, most organisms have evolved to rely on this gas. However, there are some places where oxygen-averse microorganisms like those from Earth’s earliest days have re-emerged. And one such place is hidden high in the Swiss Alp’s Piora Valley. Nicola Storelli and Daniele Zanzi dive into the depths of Lake Cadagno. Lesson by Nicola Storelli and Daniele Zanzi, directed by Ivana Volda, Thomas Johnson Volda. A special thanks to Francesco Di Nezio, Bruno Giussani, Raffaele Peduzzi, Sandro Peduzzi, Samuele Roman, and Mauro Tonolla who provided information and insights for the development of this video.
