Sir James Hopwood Jeans OM FRS (11 September 1877 – 16 September 1946) was an English physicist, astronomer and mathematician.
One must stand stiller than still. On reverse time travel.
In real science a hypothesis can never be proved true. . . A science which confines itself to correlating phenomena can never learn anything about the reality underlying the phenomena, while a science which goes further than this and introduces hypotheses about reality, can never acquire certain knowledge of a positive kind about reality; in whatever way we proceed, this is forever denied us.
We have already considered with disfavour the possibility of the universe having been planned by a biologist or an engineer; from the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.
The motion of the stars over our heads is as much an illusion as that of the cows, trees and churches that flash past the windows of our train.
The human race, whose intelligence dates back only a single tick of the astronomical clock, could hardly hope to understand so soon what it all means.
Science should leave off making pronouncements: the river of knowledge has too often turned back on itself.
We may as well cut out group theory. That is a subject that will never be of any use in physics.
Sciences usually advances by a succession of small steps, through a fog in which even the most keen-sighted explorer can seldom see more than a few paces ahead. Occasionally the fog lifts, an eminence is gained, and a wider stretch of territory can be surveyed-sometimes with startling results. A whole science may then seem to undergo a kaleidoscopic rearrangement, fragments of knowledge sometimes being found to fit together in a hitherto unsuspected manner. Sometimes the shock of readjustment may spread to other sciences; sometimes it may divert the whole current of human thought.
Put three grains of sand inside a vast cathedral, and the cathedral will be more closely packed with sand than space is with stars.
Humanity is at the very beginning of its existence-a new-born babe, with all the unexplored potentialities of babyhood; and until the last few moments its interest has been centred, absolutely and exclusively, on its cradle and feeding bottle.
The really happy person is the one who can enjoy the scenery, even when they have to take a detour. [make the best of what is necessary. . . if you can't have what you love, love what you have. . . as there are lovable or at least positive aspects in everything, because anything could be worse]
. . . to many it is not knowledge but the quest for knowledge that gives greater interest to thought-to travel hopefully is better than to arrive.
The plain fact is that there are no conclusions. If we must state a conclusion, it would be that many of the former conclusions of the nineteenth-century science on philosophical questions are once again in the melting-pot.
The universe can best be pictured as consisting of pure thought, the thought of what for want of a better word we must describe as a mathematical thinker.
