Yesterday was (depending upon who’s counting) the 16th anniversary of that thing we call the World Wide Web becoming a public entity. The Web is not to be confused with the Internet, which is much older, of course1. I’m talking about Tim Berners-Lee’s idea and implementation thereof. (I should not neglect to mention that this was done at CERN, the particle physics laboratory in Europe.) His original posting (on the newsgroup alt.hypertext) proposing the structure can be viewed here, and here’s an extract:
The project started with the philosophy that much academic information should be freely available to anyone. It aims to allow information sharing within internationally dispersed teams, and the dissemination of information by support groups.
The WWW world consists of documents, and links. Indexes are special documents which, rather than being read, may be searched. The result of such a search is another (“virtual”) document containing links to the documents found. A simple protocol (“HTTP”) is used to allow a browser program to request a keyword search by a remote information server.
The web contains documents in many formats. Those documents which are hypertext, (real or virtual) contain links to other documents, or places within documents. All documents, whether real, virtual or indexes, look similar to the reader and are contained within the same addressing scheme.
To follow a link, a reader clicks with a mouse (or types in a number if he or she has no mouse). To search and index, a reader gives keywords (or other search criteria). These are the only operations necessary to access the entire world of data.
What am I going to do to celebrate?
Since everyday I celebrate the WWW by using it a lot, to commemorate the event I think I’m going to pay a visit to the (real, physical) library, then read a good old-fashioned book for a while, and then hand-write a letter. I used to write so many letters, long ago, and from time to time I try to stop everything and pick up a pen and write one. I got in the mood the other day while in Aspen, and went and found some letter-writing paper and envelopes, curled up on a sofa, and wrote for a good while, putting it all into an envelope and posting it the next day. It’s quite a feeling, letting your thoughts build up and sort of get bottlenecked behind your slowly working hand. My writing is now so slow and so unlovely compared to how it used to be. Typing on computers has diminished my writing skills somewhat. I actually still do a fair bit of writing by hand: Of course, my research notes on what I’m doing, the actual work of my computations, writing lecture notes, and so forth. I also sometimes write drafts of introductions to (and sometimes other sections of) my research papers by hand, which I understand is very unusual these days. Sometimes I’m just in the mood to do it that way. But writing a letter (that someone else will read) swiftly and steadily, by hand, is a different thing altogether.
Now I know that the appearance of the WWW really has nothing to do with the much earlier advent of email, which is what, along with the telephone, eroded the popularity of the art of letter-writing so much, but I still think of it as one of those things that has definitely eaten into that down time that we used to reserve for writing letters. Then of course there are blogs, which serve a lot of the purpose that the letter used to – catching up on what your friends and relatives are doing… So I’m not too off the mark.
By the way, some time ago I talked about letter writing in a blog post, and not long after, I got some letters and a card in the mail from some very thoughtful readers of the blog! Thanks so much! They were an unexpected delight! There was one case where I could not acknowledge receipt to the writer (from New York) because I could not read their signature very well, so if you’re reading – thanks!
Oh. So I’ve talked about reading and writing, so what about the arithmetic promised in the title? Hmmm. Ok, on the right is an Ulam spiral2, and I’ll leave you to use the wonder of the WWW to learn exactly what one of those remarkable things is, if you don’t know. It’s a visual mystery about prime numbers.
