Scientists have an impact on nearly every part of our lives, from our medicine to our food packaging to our growing understanding of our place in the universe. Science can also be a source of inspiration and even spirituality for many people. One of science’s most wonderful and, at times, confounding qualities is that it’s constantly evolving, like a vast detective hunt in which the mystery has no known end.

Humans have been observing and experimenting with the world around us since the beginning of history, from early hunting and planting strategies, to mathematical and astronomical theories, right up to our exploration of Mars and genetic engineering. From astronomers to physicists, scientists devote their life to questioning and exploration, sharing their results with other experts and the public as they go. As the 10 quotes below reveal, many scientists engage the most fundamental and perplexing aspects of our universe. They grapple with life’s most challenging questions, such as the purpose of human existence, the role of faith, and the essence of love.
