# Thread: Introductory/Interesting Physics/Maths Articles for the wiki

1. ## Introductory/Interesting Physics/Maths Articles for the wiki

So I'm gonna try getting up some introductory/interesting physics/maths content for the wiki. Does anyone have any requests or ideas? Or anyone who wants to help?

2. I think a little something about the "Einstein Cross" (and related phenomena of gravitational lensing, etc) would be a fitting article for this site, considering we use it as an icon, heh.

Anyhow, from a sysop (not contributor) perspective, let me know if there's anything I can do to help. The wiki software's a little buggy at the moment once you get off the main rails of the basic functionality, so I'm on standby to deal with any problems.

That's a great idea, will be a good excuse to get some basic general relativity up. Trying to avoid too much maths will be a fun challenge

And thanks, will do!

I think you should teach everyone General Relativity - with a charismatic but deep presentation style - and then as a flourish at the end of the series demonstrate the mathematical structure of the Einstein cross.

That could actually be pretty fun. My GR is pretty rusty too, so would be a good excuse to brush up. Making GR 'introductory' is the thing I had trouble with the last time I thought about this. If enough people showed an interest I'd probably actually try this though - it didn't really go anywhere last time because nobody seemed to care :P

6. There used to be a decent-ish video called "Calculus in 60 Minutes" or the like on YouTube. As one would imagine, it placed greater emphasis on entertainment than on understanding, though.
