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
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
