Whether in the intellectual pursuits of science or in the mystical pursuits of the spirit, the light beckons ahead, and the purpose surging in our nature responds.

The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.
Interpretation
The quote discusses the fate of the universe as it evolves into a state of radiation, highlighting cosmic expansion.
Arthur Eddington's quote reflects on the long-term future of the universe, describing how it will eventually become a vast expanse of radiation as it continues to expand infinitely. He muses that this transformation can be seen as a grand broadcast, where the physical world's demise leads to a new phase of existence dominated by increasingly longer wavelengths of radiation, illustrating the interplay between cosmic phenomena and the nature of reality.
In practice
This quote could be used in a lecture on cosmology to illustrate the future of the universe.
Whether in the intellectual pursuits of science or in the mystical pursuits of the spirit, the light beckons ahead, and the purpose surging in our nature responds.
The physical world is entirely abstract and without actuality apart from its linkage to consciousness.
It is one thing for the human mind to extract from the phenomena of nature the laws which it has itself put into them; it may be a far harder thing to extract laws over which it has no control. It is even possible that laws which have not their origin in the mind may be irrational, and we can never succeed in formulating them.
Whatever else there may be in our nature, responsibility toward truth is one of its attributes.
In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. ... The frank realisation that physical science is concerned with a world of shadows is one of the most significant of recent advances.
So far as physics is concerned, time's arrow is a property of entropy alone.
Scientific understanding is often beautiful, a profoundly aesthetic experience which gives pleasure not unlike the reading of a great poem.
The danger is that the compromises and special interests inherent in Kyoto-style targets and cap-and-trade will be accepted because of bureaucratic momentum.
All civilizations become either spacefaring or extinct.
Receiving the National Medal of Science is the thrill of a lifetime, but good science does not happen in isolation.
As history proves abundantly, mathematical achievement, whatever its intrinsic worth, is the most enduring of all.
It was strange, in a way, because there were no ideas involved in the laser that weren't already known by somebody 25 years before lasers were discovered. The ideas were all there; just, nobody put it together.
