  • I use Excel to calculate the ages of the oldest rocks in the Solar System. If I was using it to find accounting loopholes for a private equity firm, I’d probably kill myself.

    Ted’s problem is that he equates the tools and the processes of post-industrial society with its people. Just because the possibility exists for these surrogate activities to replace meaningful work doesn’t mean we all succumb automatically.

    These social customs are derived from genuine interactions with friends. I’m curious how you deal with talking to people you care about? When I ask my friends how they are doing I’m actually curious about their lives, and I expect them to also be curious about mine. This type of reciprocation is necessary for a friendship in my opinion.


  • I’m a planetary scientist so technically this is a field, you can also be into meteorites as a hobby.

    Chondrule formation. These are spherical balls of formerly molten rock that solidified and clumped together to form chondrites, some of the oldest rocks in the Solar System that predate planet formation. Essentially these are nebular dust grains that formed when the Solar System was still an accretionary disk.

    Except, do chondrules predate planet formation? What causes them to melt while they’re floating around? How do they overcome the kinetic barriers to agglomeration? Are the terrestrial planets, whose bulk composition is thought to be chondritic, actually composed of chondrites?

    If you want to see one of the most simultaneously esoteric and bitter scientific debates, attend a chondrule formation session at a meteorite or planetary science conference. MetSoc is a great one in August, and officially I go to present my work but actually I just love the fireworks. As an achondrite person, I don’t touch this topic with a ten foot pole, but I love to watch when someone introduces a new wacky idea (space lightning? Shine from a molten Io? Extrasolar?) and you see 15 eminent greybeards rush the mic to yell their objections.
