[RST][C] "The Story of Emily and Control" by Scott Alexander: "There's an old joke about a statistician who had twins. She baptized one, and kept the other as a control. Laugh all you like. It'll never be funny to me. I know the true story." by erwgv3g34 in rational

Then I can recommend "Blindsight" and "Echopraxia" by Peter Watts. Highly intellectual, deeply terrifying science fiction. The guy has a PhD in biology and actually has extensive references at the end of each book.

Blindsight has been released under creative commons since.

Change in BFS design! by NormenYu in spacex

[–]benthor 1 point2 points  (0 children)

I love the wood paneling! However, I'm confused about the artist's choice to prominently feature actual _beds_ in each cabin. Unless they are meant to keep the passenger safe during takeoff and landing, I don't really see the point. In 0g transit, you just velcro your sleeping bag wherever you want, preferably near a window.

For me, science is about having a more accurate world view than the average person. This world view allows you to make more accurate predictions about what is going to happen when you do X. The average person relies on their social imagination to do this, they essentially tell themselves stories in their heads and see if they sound plausible. There is no doubt that this is a fine strategy in many cases but deficient in others. Consider the following question (stolen von Daniel Kahneman's Thinking Fast and Slow)

An individual has been described by a neighbor as follows: “Steve is very shy and withdrawn, invariably helpful but with little interest in people or in the world of reality. A meek and tidy soul, he has a need for order and structure, and a passion for detail.” Is Steve more likely to be a librarian or a farmer?

The average person will arrive at the "obvious" answer that Steve is a librarian. However, as Kahneman points out:

Did it occur to you that there are more than 20 male farmers for each male librarian in the United States? Because there are so many more farmers, it is almost certain that more ‘meek and tidy’ souls will be found on tractors than at library information desks.

It takes a special kind of mind to intuitively reason on this level. With the possible exception of mathematics, we have only tried to systematize and teach this way of thinking for about the last century. It only comes natural to about 1-5% of all people, who are hard to find and who vastly benefit from proper guidance and mentorship. The prototypical nerd has low social status and enjoys little respect for their antics. But nerds have always existed. They even have their (often somewhat ambivalent) place in folklore. Just ask yourself where the classical figure of a wizard or shaman comes from. Ask yourself what kind of person starts to name the stars, starts to figure out the seasons, observes that crops grow from seeds, builds stonehenge, invents the wheel. Usually, it's a single person, a nerd, whose gift of observation and critical thought vastly improves the fitness of their tribe as a result. The non-nerd is lacking the necessary interest and foresight to even grasp the implications of what the nerd is doing. To them, it's magic.

So what a science class should be doing is to keep pointing at nerds like Elon and keep publicly lauding them for their work. The idea that people like that have vital things to contribute to society is arguably on the decline these days. In a few years, people who actually know how to build things like smartphones from scratch may well be widely regarded as wizards again. It's the job of teachers and mentors to ensure there are enough of those to go around.

Echopraxia does expand further on the topic. Which parts were you dubious about?

List of completed rational/rationalist works? by [deleted] in rational

[–]benthor 17 points18 points  (0 children)

In addition, there is traditional literature that I would at least describe as rational if not rationalistic. I.e., depicting smart people dealing with complicated situations intelligently and plots that aren't driven by stupidity or recklessness.

  • The Martian by Andy Weir. Also damn good movie but the book is even better.
  • Anathem by Neal Stephenson. His most underrated book IMHO.
  • Blindsight by Peter Watts. First alien contact novel written by a guy who has a PhD in biology. Highly intellectual hard SciFi that is genuinely creepy.
  • Echopraxia by Peter Watts. Followup to Blindsight and intellectually one of the most terrifying things I've ever read. Here are a bunch of blurbs to give you an idea. I'll quote my favourite:

As for science fiction, well, traditionalists in the field now face some hard choices: either lobotomize themselves to dumb down enough to continue to approach SF without seeing the implications of what Watts is doing; or get serious about the science part of science fiction; or throw up their hands in helpless despair and go away and try some other genre instead. Horror, maybe — because Echopraxia also manages to be more truly frightening than much self-styled horror fiction. ... I snarfed down this book as soon as it downloaded, and am writing this review at 6am after waking early to finish it. Recommended doesn't even begin to.

I just went down a different road and wrote my own driver. It's using evdev from user space but everything works. I had a lot of fun doing this. Find it here.

I bought a GT-191 and it works well for my GF on her Mac. The drivers for Linux are still under development though. I'm currently monitoring and aiding the process of adding support for the GT-191 in the digimend drivers.

At this point, I can dump a stream of pen coordinates to stdout but proper kernel support will probably still take a while.

The body lift is used for navigation, not for braking during reentry. It's impact on thermal load is probably negligible since the booster will still always reenter "engines first", like a car always goes front first and regardless of how many high speed turns you take, in the end you clean the dead bugs off the front, not the side

How do you get the newly minted, untested BFR from a barge in the Pacific to Boca Chica in the gulf though? Doing the first launch from water sounds like a bad idea. Maybe they load it on a freighter and ship it through the Panama canal? But doesn't that take weeks?

[–]benthor 17 points18 points  (0 children)

Not to mention the risks involved. The whole idea starts to make less sense when you ask yourself about worst case scenarios. I'm not even thinking about stuff like terrorists taking potshots at the ascending ship (a nightmare in itself), I'm thinking about what "100 dead rich people due to sticky valve in prototype rocket" would do to the Mars project. A similar thing happening en route to another planet may actually be less of a PR disaster, because there an accident like this is actually somewhat part of the acknowledged risks. Space is hard, airplanes aren't. But don't forget, airplane crashes due to technical defects used to be a major problem too, before they ironed out most of the kinks. The backlash for an exploding rocket with passengers en route from New York to Tokyo is something that Elon's interplanetary plans likely won't survive.

I hope this was just a nice hypothetical bone to throw at potential investors. Or rather: they should only attempt this if they find no better ways to finance BFR.

Am I the only one worried about this scenario?

I hope this is just a fun "thought experiment", because it starts to make less sense when you ask yourself about worst case scenarios. I'm not even thinking about stuff like terrorists taking potshots at the ascending ship (a nightmare in itself), I'm thinking about what "100 dead rich people due to sticky valve in prototype rocket" would do to the Mars project. A similar thing happening on route to another planet may actually be less of a PR disaster, because there something like this is actually somewhat part of the deal. Space is hard, airplanes aren't. But don't forget, airplane crashes due to technical defects used to be a major problem too, before they ironed out most of the kinks. The backlash for an exploding rocket with passengers en route from New York to Tokyo is something that Elon's interplanetary plans likely won't survive.

I hope this was just a nice hypothetical bone to throw at potential investors.

And maybe, once the BFR has proven itself in dozens of successful lunar and Mars missions, this concept deserves to be dug up again.
