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.

Interpretation

What this quote means

This quote reflects the idea that our understanding of reality, especially in physics, is merely an interpretation of underlying truths.

Arthur Eddington's quote emphasizes that the realm of physical science reveals a deeper, often abstract, representation of reality. He suggests that what we perceive as the physical world is akin to shadows cast by the true nature of existence, highlighting the limitations of our understanding and the symbolic nature of scientific inquiry. Eddington argues that recognizing this distinction is crucial for grasping the complexities of life and the universe.

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.

So far as physics is concerned, time's arrow is a property of entropy alone.

A star is drawing on some vast reservoir of energy by means unknown to us. This reservoir can scarcely be other than the subatomic energy which, it is known exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service. The store is well nigh inexhaustible, if only it could be tapped. There is sufficient in the Sun to maintain its output of heat for 15 billion years.

Thin ribbons of fear snake bluely through you like a system of rivers. We need a cloudburst or soothing landscape fast, to still this panic. Maybe a field of dracaena, or a vast stand of sugar pines—generous, gum-yielding trees—to fill our minds with vegetable wonder and keep dread at bay.

Erotic acts are instinctive; they fulfill a role in nature. The idea is familiar, but it is one that contains a paradox: there is nothing more natural than sexual desire; there is nothing less natural than the forms in which it is made manifest and satisfied.
