✊✨ John Lewis was just 20 years old when he began using peaceful protest to challenge segregation, a commitment to "Good Trouble" that helped reshape the #USA.

This #video follows his life from a student activist in #Nashville and a Freedom Rider to the youngest speaker at the March on #Washington and a longtime leader in the U.S. House of Representatives.

💁🏻‍♀️ ICYMI: 🚢🧪 Maintaining a constant depth is one of the hardest parts of #underwater #engineering.

The latest build from Brick Experiment Channel solves this using a Raspberry Pi Zero 2 and a medical syringe as a ballast tank. By pulling water in or pushing it out, the system achieves neutral buoyancy. This allows the #LEGO vehicle to sit suspended in the #water.

#Biomechanics researcher Víctor Ortega-Jiménez spent five years figuring out their secret: feather-like oars on their middle legs that deploy and collapse in just 10 milliseconds. Engineers are now building small #robots that mimic these water-skating abilities.
