“Fifty years ago, when the WWF was founded there were about three billion people on earth. Now there are almost seven billion. Over twice as many - and every one of them needing space. Space for their homes, space to grow their food (or to get others to grow it for them), space to build schools and roads and airfields. A little of that space might be taken from land occupied by other people but most of it could only come from the land which, for millions of years, animals and plants have to themselves.”

“What makes love making and reading resemble each other most is that within both of them times and spaces open, different from measurable time and space”

"If on a winter's night a traveller". Chapter 7. Translated from the Italian by William Weaver (1981).

“Minkowski… supposed that this fourth dimension of time was not detached from and independent of the three dimensions of space. He introduced a new four-dimensional space to which ordinary space contributed three dimensions, and time one; we may call it 'space-time'…. The succession of positions which a particle occupied in ordinary space at a succession of instants of time would be represented by a line in space-time; this he called the 'world-line' of the particle…. Newton's absolute space and absolute time fell out of science, and they carried much with them in their fall. First to go was the concept of simultaneity…. It now became necessary to find a way of treating gravitation which should not involve simultaneity. Einstein found through the medium of his 'Principle of Equivalence'.”

James Jeans (1877–1946) British mathematician and astronomer

The Growth of Physical Science (1947)

“Looked at from the perspective of twentieth-century earth, we see three great stages in the dynamic process of the universe. To this whole process, as it spreads out over perhaps ten billion years of time and ten billion light years of space, we give the name evolution, and we see three great patterns within it. The first is physical evolution.”

Kenneth E. Boulding (1910–1993) British-American economist

This presumably started with the development of the most elementary particles (whatever they may be); then of neutrons, protons, electrons, and radiations; then of elements from hydrogen to uranium and beyond formed by combining protons and electrons; then of chemical compounds; then finally of increasingly complex molecules from amino acids, and proteins to the great watershed of DNA, the beginnings of life.

“The truth is that other systems of geometry are possible, yet after all, these other systems are not spaces but other methods of space measurements. There is one space only, though we may conceive of many different manifolds, which are contrivances or ideal constructions invented for the purpose of determining space.”
