We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier… — Edwin Powell Hubble Copy Share Image
Wisdom cannot be directly transmitted, and does not readily accumulate through the ages. — Edwin Powell Hubble Copy Share Image
A scientist naturally and inevitably ... mulls over the data and guesses at a solution. He proceeds to testing of the guess by new… — Edwin Powell Hubble Copy Share Image
Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation. — Edwin Powell Hubble Copy Share Image
The great spirals, with their enormous radial velocities and insensible proper motions, apparently lie outside our Solar system. — Edwin Powell Hubble Copy Share Image
Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation. — Edwin Powell Hubble Copy Share Image
Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive… — Edwin Powell Hubble Copy Share Image
With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary-the utmost limits of our telescopes. There, we measure shadows,… — Edwin Powell Hubble Copy Share Image
I knew that even if I were second or third rate, it was astronomy that mattered. — Edwin Powell Hubble Copy Share Image
There we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. — Edwin Powell Hubble Copy Share Image
