Internal links and syntax[edit]

If you have never used this tool before, I recommend it: http://can-we-link-it.nickj.org/. You just type (or copy) the name of an article in the box, and Nick rummages through your article, to end up by suggesting many different internal links which you might have overlooked. Most of them are good; some are not (you have to check). Nick won't make any suggestions until the syntax of your article is correct: Usually bad syntax is caused by stray brackets or apostrophes in the copy. Nick provides you with a list of the bad apples, but then you have to seek them out. A fairly easy way is to copy the text into a word processor and then search for the stray marks there. (The new links for this article are indicated here.) Of course one must be cautious in doing so and not engage in linking just for the sake of linking. I hope this has been helpful. Again, I recommend using Nick's very valuable tool. Yours sincerely,

Bristol upbringing[edit]

I've stuck up on flickr one pic of a house in Bristol (Cotham Road, Bristol, BS6) which has a [1] under a CC, license; anyone is free to stick it up on wikimedia and then link to it from here. There's another house in bishopston where he apparently grew up, 15 monk road, which is on streetview [2]. I could try getting a photo of that one too.

What I don't have is reliable data on when he lived in these houses, indeed, it's not clear that paul himself lived in cotham road, or whether it was just his parents and elder brother.

According to Farmelo's biography, the move to Monk Road took place in April 1913, when Paul Dirac was 10.Redcliffe maven (talk) 17:36, 30 December 2015 (UTC)

Requested Citation for Dirac's magnetic monopole claim[edit]

Hi,

It's quite weird that I was required to post here, as you have forbidden unregistered users from making (productive) edits.

But, I digress. I would like to tidy up the statement for which a citation was requested by User:Ashiataka and also, of course, provide the citation.

The claim is "In 1933, following his 1931 paper on magnetic monopoles, Dirac showed that the existence of a single magnetic monopole in the universe would suffice to explain the observed quantisation of electrical charge"

However I think this is slightly incorrect. I do not think the year 1933 is involved at all.

From what I can gather, Dirac was saying the existence of any magnetic charge implies that electric charge is quantised. The introduction of the theoretical construct of a magnetic monopole merely facilitated a framework where one could assume such a charge exists. Indeed, if User:Ashiataka took a few minutes (if that) to read the magnetic monopole page, a similar argument to the one above is provided (with additional citations). I therefore believe the passage should therefore read something like:

"In 1931, Dirac proposed that the existence of a single magnetic monopole in the universe would suffice to explain the quantisation of electrical charge" [1]

Thank you for this citation, which I have now added to the article. The block on nonregistered users has been placed because of past vandalism of this article. The simplest way to get permission to edit protected pages is to register. Dirac66 (talk) 01:42, 20 May 2016 (UTC)

Dirac denounced Quantum Field Theory[edit]

At 42:30 into this video, Dirac denounced Quantum Field Theory as an abomination. Should not this be reflected in Wikipedia's article? https://www.youtube.com/watch?v=jPwo1XsKKXg — Preceding unsigned comment added by 47.201.179.7 (talk) 04:33, 16 January 2017 (UTC)
