“Color is primarily Quality. Secondly, it is also Weight, for it has not only color value but also brilliance. Thirdly, it is Measure, for besides Quality and Weight, it has its limits, its area, and its extent, all of which may be measured.Tone value is primarily Weight, but in its extent and its boundaries, it is also Measure.Line, however, is solely Measure.”

On the creation of research institutions, in a speech to the Indian National Science Academy (1963), as quoted in the "Homi Jehangir Bhabha" profile at the Vigyan Prasar Science Portal
Context: I feel that we in India are apt to believe that good scientific institutions can be established by Government decree or order. A scientific institution, be it a laboratory or an academy, has to be grown with great care like a tree. Its growth in terms of quality and achievement can only be accelerated to a very limited extent. This is a field in which a large number of mediocre or second rate workers cannot make up for a few outstanding ones, and the few outstanding ones always take at least 10-15 years to grow.
Too many of our National Laboratories have been established by deciding upon the field in which it was desired to work and by drawing up an organisational chart on the pattern of some corresponding large laboratory abroad. It was then assumed naively, that the posts in the chart could be filled by advertisement, forgetting that workers of the appropriate and high level either do not exist in India, or can only be obtained at the cost of some other institution, which thus becomes weaker of it. Our Universities, weak as they always were, have been further weakened in this matter.
