In these lectures we will develop a quantitative model to describe the structure of the observable Universe as a whole. To begin, let us review the relevant physical scales. An Earth mass is 6× 1027 g ≃ 3 × 1051 GeV/c2 ≃ 3× 10−6 M⊙. Its radius is 6.4 × 10 8 cm. It spins around the Sun, which has a mass M⊙ = 2 × 10 33 g ≃ 1057 GeV/c2 and radius R⊙ ≃ 7 × 10 10 cm. The Earth-Sun distance is 1AU = ...

Recent healthcare legislation, financial pressures, and regulatory oversight have increased the need to create improved mechanisms for performance measurement, quality management tracking, and outcomesbased research. The Anesthesia Quality Institute (AQI) has established the National Anesthesia Clinical Outcomes Registry (NACOR) to support these requirements for a wide-range of customers includ...

This certainly is the ideal form of a distributed system, where the “implementation detail” of building a powerful system out of many simpler systems is entirely hidden from the user. Are there any such systems? Unfortunately, when we look at the reality of networked computers, we find that the multiplicity of system components usually shines through the abstractions provided by the operating s...
