One such example of group stupidity is the case of Influenza vaccinations here in Israel.

not a planet (it didn't clear out its orbit...), I now learned that Earth's doesn't have life on it. Sounds strange? Well, Navarro-González et la., in a recent paper that appeared in PNAS, showed that the same tests used on the Viking program and that came out negative for life on Mars, showed negative results also in ...

The other day I found out to my dismay that the balcony underneath my air conditioner at home leaks water into the living room below it. Instead of sealing the balcony (as I should...) I temporarily solved the problem by placing a baby bath tub underneath. After "recycling" the water on the lawn, I wondered, could A/C reclaimed water be economically useful?

- Passing the Eddington limit without getting a ticket: A detailed summary of the theory of porous atmospheres and how they can explain the existance of super-Eddington objects.
- Standing on Ice? Ever wondered how cold should it be and for how long, if the ice is to be thick enough for you not to fall through it?

I just recently read Motl's post on a particularly prolific crackpot, who solved all of the known problems in physics, and then some more. That reminded me of an old story, a true one, which teaches us that you can be a crackpot in many orthogonal ways (that is, in mutually independent ways).

A few days ago I stumbled upon an interesting article from Time magazine, entitled: "Another Ice Age?". No it is not a recent article. It is politically incorrect to talk about global cooling these days. The article appeared in 1974, after "three decades of cooling" prompted some to believe that an imminent ice-age may be coming. It is interesting to read it in perspective, and perhaps there is a lesson we could learn from it. Here are a few excerpts from it. Read and enjoy.
