Using Things You Can’t See to Study Things You Can’t See

How do we see things that are too tiny to actually see? One way is to use beams of x-rays or neutrons, which are also invisible to human eyes, but which allow us to visualize the nanoscale in indirect ways. I will talk about (and demonstrate) how this happens, and I will relate some things I have “seen” recently, including proteins binding to surfaces and nanocapsules with the thinnest polymer shells ever created.
