You cannot hope to build a better world without improving the individuals.
In science we must be interested in things, not in persons.
I am among those who think that science has great beauty.
More and more, I feel the need for a house and a garden.
Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.
All my life through, the new sights of Nature made me rejoice like a child.
