An ambulance passes you, and the siren drops in pitch. You have just witnessed the same phenomenon astronomers use to measure the expansion of the universe.

The Doppler effect is hiding in plain sight. It is in the whine of a passing motorcycle, the weather radar tracking a storm toward your town, the ultrasound listening to a heartbeat, and the ancient light of galaxies rushing away from us. One simple idea about motion and waves, and it explains all of it.

Herbert Coburn takes you from the roadside to the edge of the cosmos in clear, vivid language with no equations required.

Inside, you will discover:

• Why the siren changes pitch - the intuitive picture of bunched and stretched waves, finally made obvious
• Doppler's bold idea - the claim his colleagues found reckless, and the trumpet-and-train experiment that proved it
• Moving source versus moving observer - the subtle difference most explanations get wrong
• Sonic booms and shock waves - what happens when a source catches up with its own sound
• Why light is different - the relativistic Doppler effect and what changes when nothing outruns c
• Redshift and the expanding universe - how a shift in color revealed the biggest fact in cosmology
• Hunting exoplanets - detecting unseen worlds by the wobble they induce in their stars
• Doppler in daily life - speed guns, weather radar, sonar, GPS, and the ultrasound that watches blood flow

Complete with hands-on experiments you can try yourself, this is the definitive guide to the one effect that connects a passing ambulance to the birth of the universe.

Listen to the siren fade. Then look up and see the same thing happening to the stars.
