Just puttering around. Summer was relaxing. Presently back to school, only 3 days of classes attended thus far, more physics. This is the "learn to think in the language" year, if you think about learning physics like learning a language -- as I do. Last year was "get comfortable with the sounds, learn some vocabulary" stage.

I've pretty much given up on the other place. Took way too much time. Do go back once in a while to check out the notifications, but misleading to let people believe they can converse with me at the other place. Won't happen! Have also given up on linked-in and openstudy and others -- instead just living, the real world! Want to put some of the neat science stuff I'm encountering into LJ posts.

Oh, ok, here's something that could be built, beyond my scope. Ships can have gyroscopic stabilizers, anti-roll, basically a big gyroscope down in base. So far so good. But turn the idea around -- could use big gyros in ship or aircraft, with pushers, to press axis of ship/plane vs gyros. Might be an interesting assist, especially with plane, to the usual method of control via "little flaps" (to use technical terminology). Think of rapid evasive maneuvers, or conversely an anti-jitter comfort-enhancer for passenger aircraft.

Much as I like the idea of this, one needs to understand more about the psychology of "Travel sickness" before looking too far into that, I think it may have been those Jap Maglev trains or the pendolino's early days they found that having a totally smooth ride and banking perfectly into corners was great for the stability and ride of the vehicle, but made passengers "Give it psychodelic yoedels", I can definately see that as an idea to combat the rough ride due to turbulance though, but would be extremely concerned with regards to the structural integrety of the plane, certainly large planes as if you turn them upside down, the wings cannot support themselves, let alone any extra forces placed upon them!

I've been thinking about your above comment a lot -- so though it's been a long time, you're not being ignored!

Neat about planes not being engineered to fly upside down. Makes sense.

Perhaps need to have some introduced roughness of ride, random. Reminds me of Donald Knuth's typesetting (author of TeX, etc). He found it desirable to introduce slight fluctuations in the type on page, because it was pleasing / comfortable for reading.

Another aspect -- think about sensory deprivation experiments, and we then induce (or perceive) fluctuations at lower level, which we take as thoughts or sense inputs. I visited a friend at their new house, once, which was all white -- white walls, and they had off-white furniture, very minimalist decoration. Made me uncomfortable. Our natural state is for the jungle or woods, where there is lots of random input coming all the time.
