Hi everyone! First of all, thanks for the training opportunity! I did eventually come up with 50 ideas, but I took longer than an hour. I expect almost all of them to be very very very unpractical (but that's apparently not an issue); some of them are more or less deliberately absurd (in the vein of "technically, it's not excluded by the rules..."). I do want to ask around: I personally would be in favor of a "culture of practice" here. What do you think?
Hi everyone! :)
So I'm actually introducing myself now!
I'm a long-time lurker, 21 years old, living in Germany, and I'm currently in… the equivalent of high school (my education path is pretty serpentine – long story). I will hopefully be graduating next spring/summer and then presumably study mathematics.
I actually don‘t know how I first ended up here – I vaguely remember stumbling across a few articles and then succumbing to link-hopping (resulting in a few dozen open tabs). It seems to be ages since I know about LessWrong. Also, last December I attended a meetup.
Currently, I am working myself through the Sequences; although I will probably revisit at least some of the parts... (read more)
Hi everyone! Very, very, very low confidence – these are my two very first Fermi estimates ever; so Feedback will be very much appreciated.
q1:
Let‘s assume that every train station has ten rail tracks and that every rail track at a train station is ten miles long. That makes 100 miles for every train station. How many train stations are there in the world – 10^6 (1.000.000)? Seems a bit low, let‘s go with 10^9. So that‘s 10^2 * 10^9 = 10^11 miles only for train stations.
So how long are train rails that actually connect train stations combined? Uh… Let‘s assume that there will always be two train tracks for every connection (as for both directions, one
