As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.

Summary

This quote highlights the distinction between forces that we encounter in our daily lives, such as electromagnetism and gravity, versus the weak and strong forces that are not immediately perceptible. It points out that while we are familiar with certain forces, understanding and studying the fundamental particles that contribute to these forces require advanced equipment used in 20th or even 21st-century physics. The quote underscores the notion that uncovering the intricacies of the universe often necessitates sophisticated tools and technologies beyond what we encounter in our everyday experiences.
