Just to add to your comment, even so that the energy in each pulse is less than 100 billion times less than the energy from bright sunlight emitted in a second, it is still significant, but the number of laser pulses…

FWiW you can have 3 or even more frequencies in a laser beam coherent with each other, i.e. where te phase of the waves is locked together. This allows you to interfere the waveforms of the different lasers in time, as…
Actually supercontinuum lasers are not a recombination of different (incoherent) lasers but rather a 'processed' output from a single laser. You start with a high peak power laser pulse (e.g. a femtosecond mode locked…
For linux users, a very useful app: BasKet Note Pads. It's an organization tool, you write pages with notes, format text in those notes, dragndrop files into the page, and the killer feature: at any time you can capture…
I'm in Portugal so I can't comment on your experience. In here one can get it at any 'mom&pop' hardware store, which are more common than 'Home Depot' style stores.
There is also lots of information in this page http://members.optusnet.com.au/~eseychell/PCB/etching_CuCl/i... about an alternative to ferric cloride, acid cupric cloride. It is easier to buy, since all you are doing is…

I think that it is also worth noting that there is no free, independent implementation of LabVIEW. Being dependent on a vendor is not ideal, but hey, it's life. Anyway, there are some tasks that lend themselves much…
I think you have a good point that most people prefer to use the mouse, and commands that may seem obvious for some people may not be immediate for another. A clickety pointy UI would make it's affordances more…
I had similar ideas, but I think it is technically challenging to produce such transparent displays so close to the eye (i.e. integrated in eyeglasses, for example). The eye can't focus in objects that close. One…
