A lump of magnetic putty totally engulfs a rare-earth magnet in slow motion. The actual sequence is eight times longer than this video shows. The putty will not rest until the magnet is at the center of the glob. What is this "magnetic putty"? From the YouTube link:
The putty looks and feels like regular silly putty, but the difference lies in the fact that it has been infused with millions of micron-sized ferrous particles (most often iron oxide powder). The magnetic putty is not actually magnetic by itself, since the infused particles are made of iron powder.
The presence of the strong neodymium iron boron magnet (the silver cube in the video) magnetizes the ferromagnetic particles in the putty. When this happens, the ferrous particles align with each other and this alignment generates north and south magnetic poles, making the putty into a temporary magnet. Once magnetized, the putty will remain magnetized even after the rare-earth magnet has been removed from the putty. This effect persists for a few hours until thermal agitation shakes the particles and they lose their alignment.

But I'll always be partial to lynx...
IMHO, Jan 1, 1983 should be day 1, mostly because that's when TCP/IP was adpted.
The day 2 computers 1st comunicated using TCP/IP and through a router should be regarded as the first internet-like communication, and thus this day should mak the birthdate of the internet.

I don't know, when did Al Gore say he invented it?
I second SimonSays' suggestion. January 1st makes sense, and, more importantly, is easy to remember.
With Snow Leopard and all; the upcoming iTab.
Lest it's Bill!! :P
Yup yup yup!!
:)
P.s. - Glad he's off the board!
That's a lot of buts.

"would www be the same as “internet”?"
No... the www is just one of the applications of the internet. It has a related protocol: HTTP. It has to do with the traffic and presentation of web pages.
E-mail is another application (and it's protocols, like SMTP & POP). There are many other, but www and e-mail is what interest most people.
