At a certain stage, the potential gain from further refinement is not sufficient to warrant delaying submission or to risk impeding progress with your course. Remember, you should be aiming for what is ‘good enough

If Fiber is the Medium, What is the Message? Next-Generation Content for Next-Generation Networks
By investigating price and capacity trends over the past century, Eli Noam shows that it is possible to predict the type, style, and genres of media content of a future ultra-broadband infrastructure, which allows a richer, more bit-intensive content. The nature of content is critical for the economic viability of an ultra-broadband infrastructure. This paper asks what types of media content we will have when we achieve widespread fiber optic networks. In the past, an expansion of transmission c

11.5.5 Chance

Another important source of inventions and scientific discoveries is chance, which is strongly associated with acts of insight. As well as the sort of painstaking work that either precedes an invention or goes into the steady improvement in performance, in the development of most inventions there's a moment when chance plays a part. Often people are looking for one thing but find another – perhaps working on one technology when they stumble on the principles behind another. The skill of the

1.1 A milestone in the advancement of astronomy

Unaided human eyes, well as they may serve the needs of everyday life, are not very suitable for detailed astronomical observation. First, the eye has a limited sensitivity. A distant source of light, such as a star, will not be seen at all unless the intensity of light from it reaching your eye is above the sensitivity threshold of the retina. Second, the ability of the eye to distinguish fine detail is limited by the finite physical size of the detectors on the retina and by the small apert

2.2.1 Reading diagrams: questioning what they say

With each of these diagrams, and with others you are trying to read, there are several questions you can ask.

  • What is the purpose of the diagram, that is, what is it aiming to tell us?

  • How is the information imparted?

  • What assumptions does it make about our ability to understand it?

  • What are we expected to remember?

  • How successful is it in doing all
