Not everyone studies this level of physics at all, and it certainly "gratifies one's intellectual curiosity".

Football "gratifies my intellectual curiosity". Shall I start spamming hn with football threads then? Retard.

From the HN Guidelines [1]:

> On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

> Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

Relativity was taught in Physics 3 when I was an undergraduate (Computer Science Student). However, no mention of that particular thought experiment was used in reference. If there's something to complain about, it's the source for the article, but not the scenario/thought experiment itself.

Wikipedia has a great explanation of it though: http://en.wikipedia.org/wiki/Ladder_paradox

It is just about September. Let's hope it's not an eternal one.
