We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery also has its beauty. Neither do I believe that the spirit of adventure runs any risk of disappearing in our world.
And the day came when the risk to remain tight in a bud was more painful than the risk it took to blossom.
The only risk of failure is promotion.
It takes courage to step out of the line marked 'security' into the line marked 'risk.'
Risk is an essential part of progress.
Scientists tend to risk theories they admire
All inquiries carry with them some element of risk.
