The Marvels of Modern Science
Sun, 06/15/2008 - 05:54 — Jinghao
A partnership between Duke University and Boston College resulted in the discovery of a metallic material that "absorbs both the magnetic and electrical properties of electromagnetic waves over a certain frequency range, thus turning the light into heat." Good job, geniuses. There is such a thing called dark hair (I have to deal with this all the time) and black paint, either of which does a good job of converting all incident light into heat. I don't need a degree in Material Sciences Engineering to recognize what a joke this is, and neither should anyone else.
Here's a suggestion Jay made for these brilliant scientists: "maybe they'll invent a means for people to carry portable light, so they can see into dark places."

No, but it absorbs all
No, but it absorbs all wavelengths of visible light and heats up due to the absorption. The material isn't the central focus--it's the effect and purpose.

Note that they discovered a metallic material. Metallic material is not the same as the material of hair here. Perhaps I'm reading what you said wrong, but your hair, like Katherine said, is not metal.
No, you don't need a degree to tell me the properties of color and whatever else. But can you discover something of a metal sort that exhibits those properties? Yeah, you can. That is what seems to be new here. Anyway, I'm no science major, but that's what is coming out of here.
You want black

Enjoy. 2006. Not new.
What's the difference between
What's the difference between the two studies then? Did they test things differently? Were they trying to come to a different conclusion, but failed to do so?
