Yes, you can always choose an orientation of the path but not necessarily of the manifold along the path. I understand what he was saying now and misunderstood since it is not the usual way one talks about specifying an orientation at a

Yes, I took "circle" to mean any closed path since the difference is immaterial in generic manifold. You wouldn't normally be talking about "orienting a circle" in the manner the original poster did, but I see now w

by tgb 8y ago
This depends upon the circle you chose. Nonorientable manifolds still have many orientable circles (any sufficiently small loop is orientable).

I think this is misleading or misstated. Haversine distance of points on a sphere is a monotonic function of euclidean distance, so one's nearest neighbor is the same in both. You must be warning people not to just take the sum of squa

It certainly can be a reduction if you can compost at home. The result is useful. The effort is very minimal if you don't need it to compost quickly. It doesn't need to be transported to a landfill. And my understanding is that it

The best feature of recent years was when Google started showing you information from your emails on the Android smart home screen (swiping to the left). It was brilliant: have a flight tomorrow? It would show you the information, including

Quoting the last section of the article: """The reason why purple and violet look similar to us is because they stimulate our cones in a similar way, but most other animals don’t share the same types of cones and “post-proce

Thanks for pointing this out, thought I was going crazy. So the article's explanation of why violet and purple look similar even though they are completely unrelated in spectrum is bogus (the article claims it's due to this second

For (2) you can cut out the middle man (the mirror) and have the laser just point in the opposite direction of your desired acceleration. It amounts to the same thing, assuming the mirror reflects perfectly (by conservation of momentum - th

Here's my pet conspiracy theory: cigarette companies in the US colluded to get themselves banned from marketing, thereby saving themselves tons of money. Some research suggests marketing mostly just shifts spending from one brand to an

Well, they're tracking the location of the university not the nationality of the student and the absolute best students go to MIT/Stanford even if they're from outside the US. I haven't read the paper but the article her

I'm confused. If the marginal utility of a mcmansion is not ten times that of the town house, then why does the mcmansion sell for ten times the price? Are you saying it's being used as a store or value or investment or something?

I don't understand. Currently the website I'm on and the browser get access to all my keystrokes. The suggestion is to allow an <input> tab to let the browser take over and do its thing for suggesting autocompletes (whatever

It'd be your browser providing this. They already get all your keystrokes.

I was surprised when I learned that e + pi is not known to be transcendental. Everyone would be floored if it weren't, but it's still an open question.

I'm a life long morning person and avoided social outings like that for exactly this reason. I'm less reluctant to these days since I think they're actually fun but yeah I can't sleep in later than like 8 AM generally. B

I think he's wrong about people not having loyalty to meat. There is a ton of literal hatred for veganism and vegetarians in this world. Think of the practically cult-like following bacon has. I recall a thread some years ago on Reddit

The article doesn't really explain, but there's more to it than that. My guess is that the male offspring are still fertile, but carry the gene drive and so spread the infertile-female gene to all their offspring. Eventually, the
