Becoming Angela

I went for a “long” run this morning. It was an 8 kilometre run at a slower pace than I would normally run now. After Tuesday’s torturous run, today’s run felt easy! The upper leg soreness isn’t quite as bad as it was, and keeping my pace nice and slow really helped make the run feel comfortable. I finished my run in 1 hour and 3 minutes, which wouldn’t be a great time if I were running at a normal pace, but I suppose it is perfectly acceptable for a LSD (long, slow distance) run.

As I was nearing the end of my run and taking note of the time, I couldn’t help but think about the marathon in October. Here I had just run for an hour, and I hadn’t even finished 1/4 of the marathon distance. Once again doubt washed over me. What was I thinking? Did I…

The history and future of the Universe in four minutes: Brian Greene at TED2014

TED Blog

Physicist Brian Green promises he will tell the audience at TED 2014 the whole history of the universe in four minutes. “Forgive me,” he says, “if I leave out a detail here or there.”

He does it with two metaphors. One from the beginning till now, and another from now till the end.

The universe today is 13.8 billion years old, and it can be very hard to get our minds around that number. So Greene uses a metaphor pioneered by Carl Sagan. Imagine that we’re part of a single calendar year. All of cosmic history compressed into a single calendar year. On this calendar:

  • May 12, the Milky Way is formed.
  • Sept 2nd, the Earth is formed.
  • 11:40pm New Year’s Eve, Humans evolve.
  • 11:44pm, we domesticate fire.
  • 11:58pm the first cave paintings are made.
  • 11:59:49pm writing is developed, so all of recorded history takes place…
