Meet Damini Jordan & Johan Santana who are students from Renaissance Youth Center in Bronx, New York. Damini and Johan used #coding to create Blind Stick & Blind Glasses, an upgraded and hands-free version of a blind stick that beeps when the censor is activated. Their motivation for their project is to improve the lives of people with visual impairment. Press play to hear more about their project and how it works! Coding enables young people to become creative STEM problem solvers who can…

** Re-uploaded to fix small errors and improve understandability ** Do you find orbital mechanics too confusing to understand? Well, you wont after this video! In this Animation we're in space! We are going to look at why when navigating in an orbit, to speed up, you need to slow down your spacecraft! But before we answer that question, we will first review what an orbit is in the first place and what mechanical energy is! So grab a coffee and I really hope you enjoy and learn from my latest…
