    I didn't realise the TSR Cool Society would be host to such intensive biological discussion!

    yeah i gathered that's why i don't like using the word or googling the answer but is it like an emotion or a physical thing or what?
    well... it's an emotion felt when you experience a physical thing. I'm trying so hard to keep it PG hahaha awh you're so innocent bless you stay that way

    Is this cool enough for the Cool Society? I took this picture of a thin section I was looking at under the microscope today! It's basically a very, very thin slice of rock - every one of those distinct coloured blobs is a mineral crystal. The reason why they look so amazing is because the sample is in between two crossed polar filters which results in some interesting optical phenomena (which can help you diagnose the mineral) and there's also an additional filter that shifts the hue from greyscale to coloured. The colours pulsate when you rotate the stage! It's so cool...

    how do you get such a thin slice of rock?

    It takes a few stages. You firstly use a diamond saw to cut a relatively thin slice of rock and you use a special glue with the same refractive index as glass to mount the sample to a slide. You then, using a series of increasingly fine grinding surfaces, often using diamond (or other very hard substances) particles as abrasives, grind the surface down to 30 microns. If your rock isn't strong enough to withstand this process then you'd encase it in some other medium first to give it some structural integrity before grinding it down as per normal.

    Hi! :hello: We've just started our first Geophysics module today, actually. Do you still work in the field?

    nah i graduated from uni with a geophysics degree and then became a bum!I didn't mean I was a professional geophysicist. Sorry if I gave you that impression! :eek: What did you learn in your module today?

    It was just a very basic introduction (P & S waves, surface waves; vertical, radial and transverse seismographs; bulk and shear moduli and how they relate to wave velocities). About to get started on the reading we've been suggested (Global Tectonics by Kearey & Vine - I think Vine was one of the major figures in proving plate tectonics, wasn't he?).

    Didn't know his name off the top of my head but yer Vine was a legend. Free thinker and put all those sheep to shame when he was proved wrong. That's what I hate about the UK university system. Everyone gangs up on the underdog and publicly humiliates and shames them instead of encouraging free thinking and ingenuity. **** the UK academic institutions! Full of arrogant snobs! The lot of them!

    Oh dear, that doesn't give me a lot of optimism about my aim of going into research...
