quote

Today, one of my friends who is writing the final version of his thesis called me to ask about a quote from Prof. Ashby that I used it in my public defence. I wish to share it with you:

When modern man builds large load-bearing structures, he uses dense solids: steel, concrete. When nature builds large load-bearing structures, she generally uses cellular materials: wood, bone. There must be a good reason for it.
