Researchers in Germany and the United States this spring captured the first images of so-called atomic spin utilizing a scanning tunneling microscope. The telescope had an iron-coated tip to manipulate cobalt atoms on a plate of manganese. The experiment was conducted in a vaccuum at 10 Kelvin thanks to liquid helium. Results of the experiment were published in April in Nature Nanotechnology.

This progress may influence future magnetic data storage. Saw-Wah Hla, a physics professor on the team, says, "“Different directions in spin can mean different states for data storage.... The memory devices of current computers involve tens of thousands of atoms. In the future, we may be able to use one atom and change the power of the computer by the thousands.”

Quantum mechanics is strange. Probably the field's proposition that is most well-known by the general public is the dual (particle and wave) characteristic of both light and matter. How this experiment influences or confirms the theory long-term remains to be seen.

I guess this means that my 8 Gig thumb drive will grow in the future. I'm just not sure how convenient it will be to carry around liquid helium so my thumb drive will work. But, it'd be nice to have an 8 Exabyte thumb drive that's the size of a pea.

Physics professor Daniel Sheehy will be the speaker at the Highland Road Park Observatory on Friday 28 October from 7:30pm to 8:30pm. Quantum physics, his topic, is the study of single particles and small groups of particles. At that level everyday matter exhibits some very strange behavior and Dr. Sheehy is very good at describing this strange scenic to a general adult audience. The talk has no admission fee.

Don't forget Professor Sheehy's talk tomorrow night. We're quite excited as it's been a while since we've had this topic address on a Friday night.

Here's one of his articles...

Professor Sheehy returns to HRPO, this time at 4pm during NanoDays on Saturday to present "Living in the Age of Quantum Physics". This talk will bisect the demonstrations and activities suitable for younger kids.
