Powers of Ten – an oldie, but still interesting.

This might be worth a look when thinking about measurements and the significance of getting the decimal point in the wrong place. This is pretty old – going back to the 80’s by the look of things – so be aware that the units they’re using might not match the ones you need (they use microns and angstroms where DP Bio is on micrometers and nanonmeters). This in itself may be a good introduction to TOK and changing ways we view Science over time.
