"There can be no such thing as a 'pure' science, as science is always influenced by the human mind."

"The greatest joy of a scientist is to see a new truth emerge."

"It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him."

"The development of a new idea is an act of creation."

"The highest value of human life lies in its service to humanity."
