I was just watching Titanic and spent 20 minutes looking up the effects of hypothermia and discovering that Jack may have been alive and in stage 3 hypothermia when Rose let go, and because he sank instead of floated, he was in fact alive. It was a fun little time sink. What rabbit holes have you done down recently?

    Learning about Space. There we’re working miniature prototypes of a ship to get humans up to 12% of Speed of Light. Project Orion worked by blasting nuclear bombs behind a ram jets once per second.

    The concept of time and higher dimensions. I don’t understand the physics, but listening to others explain the concepts and spending time to think about it can keep me busy for hours

      I always have such a hard time with the 4th dimension concept. (Not the time one though, the other one) Sometimes I grasp it for a bit and then minutes later I’ll be confused again.

    Ham Radio.

    It started with a pair of two-way walkies, talking with a friend in the backyard while sitting in my bed and then you’re pointing to satellites and the ISS to download weather and old space images.

      I love radio stuff, but I just haven’t dove into Ham yet. That said there a local radio shack with their call signs posted on the window so I might just dig in.

      Maybe find my excuse to actually use gnuradio for something.

        Sure. Ham people are always open to share their knowledge.

        With gnuradio you can download weather imagery with a RTL SDR dongle.
