Talk:2

Etymology

I can see a typo 'combare' instead of 'compare'. Please fix it. 46.242.13.140 (talk) 10:39, 5 June 2023 (UTC)

Thanks. I just removed the paranthetical comment. It is not adding anything to the explanation, which already compares with "who". Sirfurboy🏄 (talk) 12:24, 5 June 2023 (UTC)

Conway joke

The bit I removed... Guy and Conway wrote: "Two is celebrated as the only even prime, which in some sense makes it the oddest prime of all." This is a joke, because of the incongruousness of applying the ordinary meaning of "odd" to an even number. This does not mean that the number 2 is ever actually referred to using the expression "the oddest prime". Of course JHC and RKG are as impeccable a source as you could have for a maths article, but I do not think this adds anything in an elementary exposition of the properties of 2.

Humor can aid the learning process. People are capable of differentiating terms, especially when described appropriately. Memory improves drastically when information is diversified properly, without lending to confusion, and when the information is tied to things not directly related to what is being presented at hand that others might find meaningful. I would prefer to re-include this in a note, since it is a historically valuable quotation from a reliable source, however I see your point and it is valid, though I believe it can still be incorporated in a more indirect way. Radlrb (talk) 17:03, 25 September 2023 (UTC)

Yes, but Wikipedia is supposed to be an encyclopedia. It is supposed to give an overview of a topic to the general reader (at least as far as this is possible within the constraints of necessary technical background). It is not supposed to include everything anyone can find in a Wreliable source that might have some connection with the topic. As I said at 5 I do not think that the huge amounts of sometimes extremely technical content that you have been adding to these articles is an improvement. Absolutely nothing personal, but I will start an RFC somewhere to see if everyone disagrees with me. Imaginatorium (talk) 18:07, 25 September 2023 (UTC)

Alright. Please move forward with it. This quote relates entirely, which is why it has lasted so long, relevant to your point. I'd like to point out that you are not being constructive in seeking amendments, and are firing away immediately toward an Rfc. Inclusive, of me writing in your talk page a while back, yet you chose to not give a response, whatever it may mean [1]. Radlrb (talk) 21:11, 25 September 2023 (UTC)

Writing as a great admirer of the late Professor Conway, I must sadly agree that his comment is unsuited to this page. It might be used in his own article as an example of his humour, but it's not helpful in explaining the properties of the number 2. Certes (talk) 22:43, 25 September 2023 (UTC)

Its actually useful in amplifying the property of it being the singular even prime number, if one can get accustomed to the idea of being presented both a true statement and a humorous juxtaposition at once, and generate a stronger first impression. That's deeper philosophy of psychology of learning, here being a great example of this; of course it can backfire, but I rather tend on the end of generating an article suitable for all audiences on an elementary property, that might bring to light some joy, even if it is a challenge to bring together if not ready. Again, a note is actually harmless, and it being a note too would let the reader understand the nuance; esp. when including explicitly a statement about the infinitude of odd numbers.

The pool ball 2

"2" is the notable number of the second pool ball. Its color is blue.

191.255.194.29 (talk) 10:01, 30 October 2023 (UTC)

Please see related discussion at Talk:15 (number)#The pool ball 15. Certes (talk) 12:42, 30 October 2023 (UTC)

For any n from 1 to 15(?), the nth pool ball is marked n. The colour is not notable, and any generic n statement is not notable. Therefore these should not go in. Imaginatorium (talk) 13:47, 30 October 2023 (UTC)

I am asking myself: would the typical reader look for this information in 2, or in Pool (cue sports)#Equipment? However, without a good source, I'm not sure it belongs even in the latter. Certes (talk) 14:46, 30 October 2023 (UTC)

It belongs in the latter, with a source. Polyamorph (talk) 14:56, 30 October 2023 (UTC)

Semi-protected edit request on 22 February 2024

2 is the second number in the number line 74.142.90.6 (talk) 16:39, 22 February 2024 (UTC)

 Not done: There are numerous number lines. It is not the second number in the real number line, the integer number line, or even the natural number line if you include zero (which is often the case). This would also be self-referential and so not helpful to a reader. Tollens (talk) 17:38, 22 February 2024 (UTC)

Why is this page semi protected?

and 3 is not 120.21.89.235 (talk) 22:38, 21 April 2024 (UTC)

Some Wikipedia articles, such as those for political leaders, are routinely permanently protected because they would otherwise be frequent targets for vandalism. Others are protected temporarily when the level of vandalism becomes too high. That's the case here. It's perhaps time to lift the protection here. HiLo48 (talk) 02:25, 22 April 2024 (UTC)
