Video of Louis Kahn's Salk Institute by Filmmaker & architect Pablo Casals-Aguirre. It's great to see the masterpiece in action.
In the words of Louis Kahn:
"I did not follow the dictates of the scientists, who said that they are so dedicated to what they are doing that when lunchtime comes all they do is clear away the test tubes from the benches and eat their lunch on these benches. I asked them: was it not a strain with all these noises? And they answered: the noises of the refrigerators are terrible; the noises of centrifuges are terrible; the trickling of the water is terrible. Everything was terrible including the noises of the air-conditioning system. So I would not listen to them as to what should be done. And I realizes that there should be a clean air and stainless steel area, and a rug and oak table areal From this realization form became. I separated the studies from the laboratory and placed them over gardens. The garden became outdoor spaces where one can talk. Now one need not spend all the time in the laboratories. When one knows what to do, there is only little time one needs for doing it. It is only when one does not Know what to do that it takes so much time. And to know what to do is the secret of it all."

[I ask myself - would adding trees in the plaza destroy the 'purity' of form? ]
