      Nanoscience is the study of matter on the scale of ~micrometers-nanometers (0.000001 to 0.000000001 meters). A single atom is about a tenth of a nanometer! On this scale, edges don’t look sharp and objects don’t look as solid- everything gets a bit fuzzy, and physics doesn’t work the same. This is because quantum mechanics starts to take over. Nanoscience is extremely important for teenagers (how many teenagers use smart phones?). The touch screens on smartphones use nanoscience to work (when you push on them the electrical conductance changes so the phone knows that you are pushing on it). Also, some day we might build a quantum computer! And we will have to use nanoscience to do so. So, sooner or later teenagers will have quantum computers in their phones and gadgets…

      I think Physicists here will be better at answering than me. But it is the science of tiny things. Think of something tiny. Now something smaller. No, smaller than that …. SMALLER …O.k 🙂 that is the scale of nano science. Things are small, they act strangely and have great properties. Loads of cool stuff will be made from nano materials in the future, some people even say an elevator into space.
