Neil deGrasse Tyson is clearly a very gifted teacher

His daughter was very well-behaved, he said, but that's how she's always been. "Shannon has always had a great temperament," he writes. "I never had to do anything to make her behave. ... She was and is quite mature for her age."Sounds like a dad who knows his daughter.What age do you think is the right age for children to travel? Please share your family's experience in the ments below.This week's episode of Cosmos: A Spacetime Odyssey really honored the "spacetime" ponent of the series' title. Veering away from the science history vignettes of recent episodes but not their anti-creationist campaign the fourth episode in the rebooted series was all about the laws of physics, and what happens when they're broken. What if everything that is happening has already happened?Danielle: I have to say that I think this week's episode was the most informative so far. Neil deGrasse Tyson is clearly a very gifted teacher, and his explanation of Einstein's principles of relativity was illuminating. And the approach looking at how time travel works in the context of the space-time continuum, and the types of illusions we confront each day was captivating. This was also the first time he threw some hard math our way, which I enjoyed. Plus black holes are cool, and imagining what happens within a black hole is also cool.Abby: So first of all, I'm pretty sure this week's episode means that Neil deGrasse Tyson is a Time Lord. The science fiction portion of the show where Tyson slides from what we know about black holes to the coolest things we can plausibly imagine about them was a much-needed demonstration of educated fantasy. Danielle: I don't actually know anything about string theory, but this is a broad strokes explanation of string theory, right? Black holes could potentially break the laws of physics, and possibly act as a portal to other universes, or times, or dimensions? Okay I'm going to go reread Flatland and then A Wrinkle In Time, brb.Abby: Yes, good, me too. I think you're correct, although I too have a giant string theory blind spot. I know menters on the internet are really reluctant to tell someone they're wrong about something, now might be a good opportunity to try that out, people.
