Femtosecond Lasers Used To Color Metals 166
Maximum Prophet writes "An optics professor and a postgrad have developed a way to use ultra-short pulses of laser light to etch nano features into the surface of metals so that they can absorb or reflect specific wavelengths of light. This is very similar to the way that butterflies get the color in their wings."

This argument is like the quarterback vs the coach.
While the postgrad may have done 99.9999999% of the annoying and tedious labor-intensive development of the concept, it is often the case that such partnerships start with a short conversation in a hallway, where either one of them could rightly claim to have spawned the insightful flash that led to the exercise in the first place, and neither one of them could rightly deny the claim of the other. Add that to the fact that the lab is provided by the professor's tenure and grant-gathering capabilities, and you really can't say that the professor isn't entitled to being listed prominently.

*And how well a given metal accepts these markings will depend heavily on its crystal structure.
