2Physics Quote:
"Lasers are light sources with well-defined and well-manageable properties, making them an ideal tool for scientific research. Nevertheless, at some points the inherent (quasi-) monochromaticity of lasers is a drawback. Using a convenient converting phosphor can produce a broad spectrum but also results in a loss of the desired laser properties, in particular the high degree of directionality. To generate true white light while retaining this directionality, one can resort to nonlinear effects like soliton formation."

Nuclear Fusion

Today we have 3 short postings on recent happenings in Fusion research.
Nuclear fusion is the power that drives our sun and thus our life.
Supporters of nuclear fusion argue that it has the potential to be a safe and
sustainable source of energy that does not produce any greenhouse-gas
emissions or long-lived nuclear waste. A fusion reactor would need just
100 grams of deuterium and 3 tons of natural lithium to produce a power
output of 1 GigaWatt, which is equivalent to a large power station
[lithium is needed to generate tritium].
So, follow our 3 postings below:

Mary Hodder on the Flickr - Yahoo ID flap
I was struck by Mary Hodder 's take on the Flickr - Yahoo ID issue because I think she does a better job of articulating the emotional attachment aspect than I did: "Yahoo reset my cookie last week for Flickr.
