Square-Wheeled Bicycle

My father was telling me about a former math student at McGill name Stan Wagon who built a square-wheeled bicycle and a road to ride it on. Sure enough, he has a website with a photo. There's more info on the web; this article goes into more detail. Here's a quote: "Just as a square rides smoothly across a roadbed of linked inverted catenaries, other regular polygons, including pentagons and hexagons, also ride smoothly over curves made up of appropriately selected pieces of inverted catenaries. As the number of a polygon's sides increases, these catenary segments get shorter and flatter. Ultimately, for an infinite number of sides (in effect, a circle), the curve becomes a straight, horizontal line."

Ivan: What? My blog has comments?

Now that you point it out, I do recall reading your comment and going to the link...but my post was independently inspired by what my father said.

A person who is on Xanax should be extremely careful if he takes grape juice. Grape juice and the anti-anxiety medicine drug do not blend with each other quite well. Grape juice blocks a kind of enzyme, cytochrome P-450 3A4 1A2 in our intestinal wall. These enzymes are found in the liver and the intestinal tract. These enzymes are helpful in the metabolization of drugs. Drugs are mostly lipid-soluble. Cytochrome P450 enzymes break the drug in the gut itself making it water soluble, which then can be eliminated out of the body in the form of urine by the kidney. Hence it can be well understood that what a great job these cytochrome enzymes are doing. Xanax blocks this enzyme in the gut itself making the body retain the harmful effects of Xanax in the body itself, which otherwise could be eliminated from the body in the form of urine.

Xanax is an antidepressant which is basically used to treat anxiety disorders. People buy Xanax to treat all forms of anxiety disorder, be it panic disorder, obsessive compulsive disorder, post traumatic stress disorder or any other kind of anxiety disorder. Pharmacies sell cheap Xanax which can be easily availed by the people who require it. For more information on the subject log on to http://www.buy-xanax-online-now.com
