Yep I enjoyed Star Trek as a child as I now appreciate Neil degrease Tyson et al for their scientific / mathematical skill sets. As to your one question about iOS, the only iOs device I have is an iPad Air 2 128, everything else Windows PC (and a bit of Android) and sure GAS can be fun (as well as distracting alas).

I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. - Richard Feynman
