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.
A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
It is impossible to devise an experiment without a preconceived idea; devising an experiment, we said, is putting a question; we never conceive a question without an idea which invites an answer. I consider it, therefore, an absolute principle that experiments must always be devised in view of a preconceived idea, no matter if the idea be not very clear nor very well defined.
I can't imagine how many kids around the world will look at pictures of Pluto and think, 'I want to grow up to be a scientist.'
Perhaps in ten thousand years, the starry sky that humankind gazes upon will remain empty and silent. But perhaps tomorrow we'll wake up and find an alien spaceship the size of the Moon parked in orbit.
Science merely amplifies the capabilities of human beings. Science gives us the ability to do ill and to do good more than we had, and to question science in this respect is like questioning whether people ought to have two hands or just one, because with two hands they could do more evil than they can with just one.
Science is history arranged according to the superstition and taste of the moment. The vocabulary of scholars has no wit, no salt. These heavy tomes have no soul, they are filled with distress.
