Very welcomed change of offerings. With that, in our area, the primary employers are a nuclear power plant, a DEA nuclear research facility, Army Cyber, NSA, and the medical college, which makes the odds of having tech-savvy folks in the audience pretty high. According, it would have been nice for Dr. Tyson to add a “tech timeout” to provide a little more depth into the math and engineering behind Doppler, speed-of-light, etc. Especially important for the kids to see practical application of math. Also, maybe use the last 15-20 minutes for a question and answer session could be very enriching and entertaining. My 17yr old son really enjoyed the lecture. Please come back soon!
