The original Doctor Who was an educational show mostly aimed at school aged children that used a sci-fi gimmick to teach history lessons (much of which are a bit outdated now). They would alternate storylines between future and past settings through most of William Hartnell’s run.

Towards the end of classic Who it was already much more like modern Who than those first seasons.

The trick is to figure out how long you sleep naturally and go to sleep that amount of time before you need to wake up. Doesn’t work for insomniacs unfortunately.

I think if you tried the onions we have available to us, you’d understand.

Seems kind of cruel to bring back mammoths just as we’re in the process of cooking the planet.

Technology may change, but we still haven’t made anything better than microfilm or microfiche for long term document archival.

Mostly we seem to have just given up on the idea of there being a future in 500 years.

Could always do the old school google walking route and take a kayak with you.
