I can never satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model, I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand.

Mathematics as an expression of the human mind reflects the active will, the contemplative reason, and the desire for aesthetic perfection. Its basic elements are logic and intuition, analysis and construction, generality and individuality. Though different traditions may emphasize different aspects, it is only the interplay of these antithetic forces and the struggle for their synthesis that constitute the life, usefulness, and supreme value of mathematical science.
Interpretation
What this quote means
Mathematics is both a rational and creative endeavor, merging logical analysis with intuitive thought to achieve beauty and understanding.
This quote by Richard Courant emphasizes that mathematics is not only a logical discipline but also an artistic one that reflects human creativity and intellect. It highlights how the combination of different elements—such as the interplay between logic and intuition—contributes to the richness and value of mathematical science, suggesting that the synthesis of contrasting forces is essential for understanding its true beauty and utility.

Climate Change is a national security issue. We found that climate instability will lead to instability in geopolitics and impact American military operations around the world. People are saying they want to be perfectly convinced about climate science projections. But speaking as a soldier, we never have 100 percent certainty. If you wait until you have 100 percent certainty, something bad is going to happen on the battlefield.

We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going.
