In science we must be interested in things, not in persons.
“I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale.”
“All advances in engineering are tested first on small-scale models, in wave tanks, or in wind tunnels. Without models, the research would be prohibitively expensive, and progress would be correspondingly slow.”
