| Jan 5, 2016 at 17:51 | comment | added | Luis Masuelli | @katz I was wrong. I had the strange idea that hyperreal numbers were a deprecated concept. | |
| Jan 5, 2016 at 17:34 | comment | added | Mikhail Katz | @LuisMasuelli, why are hyperreal numbers examples of disappearing entities? Is this because they are ghosts of departed (i.e., disappearing) quantities? | |

| Dec 24, 2015 at 20:52 | comment | added | A.Ellett | "Mathematical discourse" is notorious for not being very clear (philosophically speaking) about what a mathematical object is. There are various philosophies of mathematics to work these things out. But most mathematicians aren't interested in such philosophy and happily change their philosophical hats, so to speak, as the occasion merits and suits their needs. A mathematician can be a Platonist one moment, in the next a Formalist, and then switch to being a Constructivist. | |

| Dec 23, 2015 at 20:23 | comment | added | user84431 | As remarked above too, I reckon my reference to objects is perhaps too loose. A a provisional attempt to clarify my question, I would say that I understand "mathematical object" as what mathematical discourse refers to (or purports to refer). In this sense, I don't see a clearcut distinction between "objects", "concepts" and "ideas". | |
| Dec 23, 2015 at 18:48 | comment | added | Kyle Strand | By "objects" do you mean "concepts" or "ideas"? | |
| Dec 23, 2015 at 17:38 | comment | added | Mikhail Katz | Yes. I constantly misplace my math books, never to be seen again. | |

| Dec 22, 2015 at 16:51 | comment | added | Patrick Stevens | I would note that the luminiferous aether as a physical entity never disappeared, because it never existed. The idea may have disappeared, but the entity did not. (I wouldn't usually pick such nits, but the question is very close to philosophy, and in such questions I think it's best to be very clear.) | |

| Dec 22, 2015 at 15:22 | comment | added | Jason Starr | In the days before computers, there were algorithms aimed at performing computations by hand with the aid of numerical tables. I remember learning about mantissas and surds in school. Apart from historical interest, those algorithms have fallen into disuse. Of course numerical analysis is essential for computation, but that is different than algorithms for computation by hand. | |
| Dec 22, 2015 at 14:57 | comment | added | user84431 | Thank you for your precisions. I would say that I agree to define "disappear" as "fall into disuse, to the point that living mathematicians practically forget about the existence of this part of mathematics". | |
| Dec 22, 2015 at 14:50 | comment | added | Gerry Myerson | They may not disappear, but functions have been known to vanish.... | |
| Dec 22, 2015 at 14:22 | comment | added | Jason Starr | Could you please define "mathematical objects"? Could you please define "disappear"? By "disappear" do you mean "fall into disuse, to the point that living mathematicians practically forget about the existence of this part of mathematics"? That certainly happens. | |
