Manhattan walk

For a two-dimensional square lattice (z=4), FH theory gives o>h = 1 104. The upper bound can be estimated by using ice model [22] to be h = (4/3) / = 1.5396. Numerical simulation evaluates o>h = 1.38. The estimate of the lower bound is possible by using the model of the Manhattan walk [23]. The Manhattan walk is a Hamilton walk on the directed lattice. Walks have to follow the arrows on the edges, which are alternately up/down and left/right, as the traffic regulation in Manhattan downtown. 

Exact solution of Manhattan walks on the square lattice is known. The number of walks is given by... 

Today, physicists would agree that time is one of the strangest properties of our universe. There is a story circulating among scientists of an immigrant arriving in Manhattan who has lost his watch. He walks up to a man on Broadway and asks, Please, Sir, what is time The scientist replies, Tm sorry, you ll have to ask a philosopher. I m just a physicist. ... 

Minkowski metric with k = 1. The shortest path from a to b walking on a co-ordinate axis. Named for the streets of Manhattan, which resemble a co-ordinate axis... 

STP was said to be an acronym for "Serenity, Tranquility and Peace, although for many it proved to be a foundation-shaking experience. Among the first to try STP was Richard Alpert, who took it in an apartment building on 57th Street in Manhattan and promptly tried to walk out the window. He was so scared by his response that he said the drug should not be released under any circumstances, that it was too intense. Later, considering that... 

Dr. Williams, by the way, gave this advice at the age of 8O/2, while striding the mile from the federation s office to his midtown Manhattan hotel. ( Can you walk that far he asked me before setting out.) He was still working almost full-time mentoring doctors at the University of Rochester hospital in upstate New York, and bicycling the six-mile round trip from home two or three times a week. He also took the stairs rather than the elevator at the hospital, worked out on a NordicTrack in his basement for 15 minutes most days, and kept to a low-fat diet. 

Just across the Brooklyn bridge, the quiet tree-lined streets and perfectly preserved brownstones of Brooklyn Heights make you wonder why anyone would want to live in noisy Manhattan. A walk along Brooklyn Height s Promenade affords aweinspiring views of the Manhattan skyline. 

Going to Work in the Morning from Brooklyn tells the story of a man who absolutely does not want to go to work, although he knows he must. We follow him in his anguished, comical struggle to get out of bed, into a suit and tie, out the door, and onto the Manhattan-bound subway. We feel his despair while we laugh at his actions the film successfully walks a fine line between comedy and drama. 

One of Olson s colleagues at Fort Detrick, Colonel Vincent Ruwet, offered to accompany Olson to New York to see a recommended psychiatrist. They were joined on the journey by a civilian, Robert Lashbrook, who worked for the Cl A. To pass the evening in Manhattan the three men went to see a musical, but Olson became so upset that Colonel Ruwet had to walk him back to their hotel during the intermission. Later, while Ruwet was asleep, Olson went out wandering the streets. At one point he apparendy became convinced that Ruwet had ordered him to destroy all his paper money, and tore it up and threw away his wallet.
