Scientists Capture Shadow Cast By 1 Atom

slew writes "Scientist at Griffith University have shown the first absorption image of a single atom isolated in a vacuum. A single atomic ion was confined in an RF Paul trap and the absorption imaged at near wavelength resolution with a phase Fresnel lens. They predict this absorption imaging technique should prove useful in quantum information processing and using the minimum amount of illumination for bio-imaging of light-sensitive samples. Here's a pointer to the paper."

    Electricity: Net charge state relayed from one atom to the next. Getting deeper than that? Good luck, our perception plays a big part in how we gauge truth and we cannot perceive this level of existence.

    Just like the Higgs Boson. It is right up there with basic photon experiments, interesting I guess, but not nearly as practical. The whole proceedings of announcements and the conference and the comments from these people flipping out over this "discovery" smacks of a cult and is way too emotional for the practical implications (zero). Grown men crying and shit about statistical readings that "they we're really hoping for," all hinging around what is a probably a politically charged project (VERY expensive Hadron Collider). My bullshit meter is going off is all, can't help it. In a time of cutbacks the Collider needs to maintain funding and notoriety--the thing cost a freaking fortune and takes a lot of money to maintain and run. I'm just questioning the value of this discovery--is the HC required to reproduce? For some strange reason people want this to be a big deal when it PROBABLY is not. For one, they assume a "big bang," which I'm not ready to assume is true because it could lead us down the wrong path of reasoning. I'm just not going to buy that this is some major discovery, until I see a practical application, just because the science community wants it to be so. As of right now, the Higgs Boson only fills in one blank in a theory, or model, with many blanks yet left.
