"Spicy world of NanoScience" since 2007
There are some common calculations done by the beginning student of nanoscience and I thought it would be good to go over some of these calculations in a video and post it to Youtube. This is mostly to help my students but others may find it useful. I was inspired by Salman Khan over at Khan Academy: http://www.khanacademy.org/ . I used three tools to create these videos. The first is SmoothDraw which is used to draw the programs: http://www.smoothdraw.com/ The second is DreamCalc which is a scientific calculator: http://www.dreamcalc.com/ . The third is Camtasia which records everything you do on the computer: http://www.techsmith.com/camtasia/. Finally I also used a Logitech web cam to record the vocals and a Wacom digitizing tablet to draw.
In this example I calculate the surface area in square meters per gram for a given type of nanoparticle.
