I made this video last week in Pyongyang, North Korea. Visited the middle school for gifted students. They have 2 floors of physics labs, and one each of chemistry and biology labs as well as an extensive mathematics program. This is a video of my visit to a physics classroom where the teacher is showing his (6th grade) students that vibrating a spring creates a standing sine wave.
Students are selected for the gifted student program when they are 6 years old and receive intensive training in mathematics and the sciences. How extensive? I visited a 6th grade biology class where the students had recently cloned a rabbit in the lab.
Tell your kids to study their math.
