   A full moon light takes away all the colours it touches, and if you stare to the grey landscape long enough it  turns blue (away from artificial lights). This phenomena is called blueshift or “Purkinje shift”. As your eyes become  maximally dark adapted, the blue appears.

But how the dark shades become blue to us is still under discussion and much controversy.

A short guide on your eye….

In our retina with have rods and cones. Cones allow us to see colors and fine details, but they only work in bright light. So it will be impossible to read a book by moonlight or glance at a red rose. After sunset, the rods take over.

Rods are very sensitive (1000 times more so than cones) and are responsible for our night vision. According to some reports, rods can detect as little as a single photon of light! There’s only one drawback: rods are colorblind. Roses at night thus appear gray.If rods are so sensitive, why can’t we use them to read by moonlight? The problem is, rods are almost completely absent from a central patch of retina called the fovea, which the brain uses for reading. The fovea is densely packed with cones, so we can read during the day. At night, however, the fovea becomes a blind spot. The remaining peripheral vision isn’t sharp enough to make out individual letters and words.

So if moonlight intensity (400 000 x fainter than sunlight) is below the cones detection threshold, cones are not being stimulated, how come we perceive the blueness ?

The question remains, although some scientists try to unveil the mystery. Some try a bio-electrical approach: that signals from rods can spill into adjacent blue-sensitive cones under conditions of full-moon illumination. This would create an illusion of blue.

GUIDA Comment 

According to the Chef that invented this recipe, after you feed this to you “honey bunny” you won’t stay single for long. It seems to be one of the most simple, yet sexyest pasta inevented so far….Huuuuuum! I think I’ll try this one friday winter night! ) )

Vodka Cream Pasta 20060228_f_120x901.jpg

1 tablespoon extra-virgin olive oil, once around the pan in a slow
1 tablespoon butter
2 cloves garlic, minced
2 shallots, minced
1 cup vodka
1 cup chicken stock
1 can crushed tomatoes (32 ounces)
Coarse salt and pepper
16 ounces pasta, such as penne rigate
1/2 cup heavy cream
20 leaves fresh basil, shredded or torn
Crusty bread, for passing

Heat a large skillet over moderate heat. Add oil, butter, garlic, and shallots. Gently saute shallots for 3 to 5 minutes to develop their sweetness. Add vodka to the pan, 3 turns around the pan in a steady stream will equal about 1 cup. Reduce vodka by half, this will take 2 or 3 minutes. Add chicken stock, tomatoes. Bring sauce to a bubble and reduce heat to simmer. Season with salt and pepper.
While sauce simmers, cook pasta in salted boiling water until cooked to al dente (with a bite to it). While pasta cooks, prepare your salad or other side dishes.Stir cream into sauce. When sauce returns to a bubble, remove it from heat. Drain pasta. Toss hot pasta with sauce and basil leaves.Pass pasta with crusty bread.
