The Fabric of the Cosmos the book, such as discussions revolving around classical physics, quantum mechanics, and cosmological physics. Chapter 2, "The Universe and the Bucket", features space as its key point. The question posed by Greene is this: "Is space a human abstraction, or is it a physical entity?" The key thought experiment is a spinning bucket of water, designed to make one think about what creates the force felt inside the bucket when it is spinning. The ideas of Isaac Newton, Ernst Mach, and Gottfried Leibniz on this thought experiment are discussed in detail. Chapter 3, "Relativity and the Absolute", focuses on spacetime.
Australasian College of Physical Scientists and Engineers in Medicine 1986. The ACPSEM facilitates training and professional accreditation for practising medical physicists in Australia and New Zealand. This includes significant support for the TEAP training program for medical physics trainees. The ACPSEM also promotes education and research into the biomedical applications of physics, mathematics, engineering and computing. The ACPSEM has an official scientific journal, Australasian Physical & Engineering Sciences in Medicine, which is published 4 times a year. The ACPSEM holds an annual Engineering and Physical Sciences in Medicine conference, and has done every year since 1961. The ACPSEM is governed by an elected board known as the ACPSEM Council,
