While the current pace of innovation seems breathtaking, here's something to consider: 100 years ago, we were not even sure what an atom was. Ernest Rutherford had to show us, with a pretty simple set of experiments, that the atom had a nucleus. 100 years later we have taken the atom for granted and criticize new tablet computers for not having a better camera. I feel like science is dissolving into the background of technology in a way that is both amazing and depressing. Our daily routines rely on devices, such as smart phones, that are infinitely more powerful than anything Rutherford had access to or could have imagined. It's all science but most people only see a logo. The iPad 2 may be near the bleeding edge of science and few users know or care.
