Science is great! Science is exciting! Science is fun! You can talk about science here! Chemistry or Physics or Biology, you can talk about all these sciences! Hurrah! Here's a contribution from me: [url]http://www.periodicvideos.com[/url] A website containing lots of videos (one for each element - and some more additional ones) giving information about them - both in general terms given by [url=http://en.wikipedia.org/wiki/Martyn_Poliakoff]Professor Poliakoff[/url], a really lovely guy who I met a couple of years back and some of his research group. There's also another website: [url]http://www.sixtysymbols.com/[/url] which is a similar sort of concept and pretty interesting - focusing on symbols, whether they be operators in equations, constants or anything else - very engrossing.
I hate chemistry at uni. I'm more of a biology kind of person.
Was considering making this myself, but yay, science chat! Today in electricity and magnetism lecture I am going to learn why a moving electric charge produces and electric field that points radially outward from it. I am excited about this.

This is our plasma reactor when it's all switched off [img]http://mikeh269.com/plasma/plasmareactor.jpg[/img] We then pumped it down to approximately 0.1mbar, allowing a stream of air to flow through from the right hand side to the vac pump on the left and struck a plasma using RF (13 MHz).
