Cell-phone and satellite communication; autonomous cars, rockets and drones; magnetic resonance imaging; atomic clocks.

What do these technologies have in common? Those who designed them studied physics. Indeed, physics forms the basis of much of modern science and technology.

But this is not the only reason to study physics. It is no exaggeration to say that studying physics leads to not just technical, but also deeply philosophical—and sometimes even theological—questions. How do magnets work? Why does iron glow when heated? And why do snowflakes have such beautiful symmetry? Is there a smallest object? Or a fastest speed? Do we all experience time in the same way? Can matter itself be created or destroyed? And is there anything that is truly eternal?

Throughout history, those who have studied physics—from Aristotle to Heisenberg— were motivated by a desire to understand nature, and to try to answer questions such as these. Would you like to join the conversation?
