Thanks to MinutePhysics, you’ll never look at this oblate spheroid you live on the same way again. Earth, and the water that covers it, is subject to a score of dips, tugs and bulges thanks to the wibbly-wobbly nature of rocky-craggy-gravity… stuff.
Anyway, the question of how high above sea level you or Mt. Everest is is a lot more fascinating and complicated than you think. Elevate your understanding!
These are may favorite science stories. Finding out that the things that just ARE, those things that we take intellectually and observationally for granted, like blue skies, wind, tall trees, or seasons … the world is even more amazing when you discover how it works. I have found no exception to this rule.
Chokecherries, on the boil. Coming soon: syrup, I’m told.
Finished reading The Cuckoo’s Calling, the mystery that J.K. Rowling wrote under a pseudonym. Great bedtime reading.
Seriously? That’s the finding of a made-to-spark-a-debate list from Paste on the worst holiday songs, from Halloween to Valentine’s. Eartha Kitt? Those are fighting words!
