6.1 Basic isotropy

As we have said, the photons in the 3 K background have been practically free from interaction with anything since about 4 × 105 years after the instant of the big bang. The present angular distribution of the microwave radiation – the way in which it is spread across the sky – is therefore almost the same as it was then. The spectrum we find today depends on the temperatures at that time – for the intensity of the radiation in a particular region of the early Unive

9 Letting go

This is the point where you have to make the decision that the assignment is complete and ready to be sent off. It is not always an easy decision to make. Perhaps you feel that there is always room for further improvement or there is something more that you could have done.

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
