摘要:
Quantum computing is a distant, albeit intensely pursued, goal. To understand its allure, consider how much more information one can process by replacing the classical bit, representing either a 1 or a 0, with a two‐state quantum system, such as an ion having two energy levels. This system, called a qubit, might be in either of its two states, representing a 1 or a 0, but it can also be in a superposition of its two states.

摘要:
The great majority of cosmic‐ray particles reaching Earth's surface are positive and negative muons. At sea level, the muon flux is about104/m2per minute. These muons are mostly decay products of short‐lived &pgr; mesons created by cosmic‐ray protons hitting the upper atmosphere. Because muons are 200 times heavier than electrons and impervious to the strong nuclear force, they are far more penetrating than electrons, neutrons, x rays, or even gamma rays. With a typical energy of 3 GeV, a cosmic‐ray muon will pass through 15 m of water or 2.5 m of steel.

摘要:
In a sense, a simple bacterium is like a soap bubble. Both consist of a fluid enveloped by a thin layer of another fluid. But poke a hole in each structure, and their resemblance ends: The soap bubble pops; the bacterium's single cell reseals. The origin of this difference lies in the competition between surface tension and its lesser‐known one‐dimensional analog, line tension.
