In science we must be interested in things, not in persons.

If it takes a hundred years, it will be a pity, but I will not cease to work for it as long as I live.

I was taught the method for advancement is not quick or simple.

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.
