It's not every day you move an atom with a mouse click. But this is precisely what I do one day at the Singularity University, a new institution supported by Google and Nasa, which aims to educate a select group of entrepreneurs and scientists about the rapid pace of technology.
The class of 40 students - who are taking time out of their working lives - has settled into a busy routine. Our 12-hour days are crammed with experiments, visits to technology centres including IBM and Willow Garage, and discussion with experts. The purpose is to open our eyes to the pace of change and future possibilities.
On Wednesday we arrive at IBM Almaden research centre, a series of black glass buildings in the hills near San Jose. Unassuming office doors open to reveal scientists working away in a scene reminiscent of a sci-fi movie. We meet Kevin Roche, who is building complex machines that can deposit thin films of atoms to form nano-scale devices.
This is where, in 1989, the physicist Donald Eigler built a scanning tunnelling microscope and demonstrated the ability precisely to manipulate individual atoms by rearranging xenon atoms to spell out IBM. In homage, we use a similar machine and write SU (for Singularity University) by selecting iron atoms with a mouse and nudging them across the screen.
We open another door and witness magnetic "racetrack" memory experiments. This is the idea of storing data in magnetic field domains that can then slide or "race" along nano-wires so they can be read quickly. The idea may help our future portable devices to store hundreds of times more video.
