Time's Arrow and Archimedes' Point: New Directions for the Physics of Time

Why is the long run so diverse from the prior? Why does the prior have an effect on the longer term and never the wrong way round? What does quantum mechanics particularly let us know concerning the international? during this very important and obtainable publication, Huw expense throws attention-grabbing new gentle on many of the nice mysteries of recent physics, and connects them in a unconditionally unique method.

Example text

Human behavior is not the only thing susceptible to explanation by reference to function or purpose. If you asked me about the rock sitting on my desk, I would offer the following explanation. A heating duct is located just over my desk, and whenever the heat comes on, unsecured papers blow about. So I use the rock as a paperweight. Following a similar strategy, we might explain that a carburetor is the component of an internal combustion engine that mixes fuel and oxygen. In both of these examples, we e>:plain by specifYing the purpose the thing in question serves.

A lake is polluted and some of its indigenous species ofwildlife begin to diminish. There seems to be a connection. But what is the process by which greater pollution leads to less and less wildlife? Similarly, if we want to understand more about wby a law-like regularity obtains, we may need to consider underlying processes. Recall our discussion earlier of Gay-Lussac's Law: if volume is held constant, the pressure exerted by a gas will vary direcdy with the temperature. Why, we might wonder, should this particular relationship between temperature, volume, and pressure hold fur gasses?

For if our psychic can do what he claims, we must take seriously the notion that forces and processes are at work in nature that have so far escaped our detection; we must begin thinking about revisions to our current understand- ing of things. SUMMARY Observation is the first step in scientific inquiry. To ensure observationaJ accu- racy, the following criteria must be satisfied. 1. Do we have a clear sense of what the relevant phenomena are? , are key terms clearly specified? 2. Can we find a way to guarancee that nothing relevant is overlooked?
