Note on "orange and not orange"
|
| Jul 22, 2019 at 22:03 | comment | added | Jasper | Even if you changed the phrase 'both orange and not orange" to "both orange and not-at-all orange", a pointillist could paint a car in completely non-orange colors, so that from a distance the car would appear to be orange. | |

justification of "for an infinity of cases"
|
| Jul 22, 2019 at 17:53 | comment | added | Torsten Schoeneberg | As an aside, there are many formulae which single out primes; if you are generous, already Eratosthenes's sieve is such a formula. en.wikipedia.org/wiki/Formula_for_primes Some mathematicians are interested in deciding how efficient such formulae can be made; I think more mathematicians are interested in problems like, what's the asymptotic density of primes in a set of the form X? That would be something like: we figured out that if we only check the lots #1, #11, #21, #31, ... we are sure there will still always come another one where all cars are orange. | |
| Jul 22, 2019 at 17:46 | comment | added | Torsten Schoeneberg | The paragraph "Thus, for an infinity of cases ..." makes no sense to me. For each single number, you can decide in principle whether it's prime; but there are infinitely many numbers. In the analogy, there are infinitely many parking lots now. Then it's not like "for infinitely many parking lots, you have to go through all cars there". Rather, you can only check finitely many parking lots anyway, with whatever method you have. | |
