Sound is a travelling wave transmitted through a solid, liquid, or gas, composed of frequencies that our ears can hear. This audiobook explores sound and it's secrets.

Examines wedges, explains their functions, and suggests simple experiments to demonstrate how they work.

Wer sich mit Einstein in einen Fahrstuhl begibt, lernt nicht nur den berühmtesten Physiker aller Zeiten kennen, sondern erlebt auch ungeahnte Abenteuer: Angenommen, das Seil des Fahrstuhls reißt. Dann zeigt eine Waage, auf der beide vielleicht stehen, nichts mehr an! Können sie dann überhaupt wissen, dass sie wirklich nach unten fallen und nicht etwa schwerelos im All schweben? Mit Experimenten und Versuchen zum Ausprobieren werden die Hörer anschaulich in die Grundlagen der Mechanik eingeführt.

Do you like to gaze at the stars? So did the young Stephen Hawking. Eventually, he turned his fascination with the night sky into a career of trying to figure out how the universe began and how it works. As a child, Hawking loved the stars and he loved math class. In college, he studied physics and cosmology, or how the universe came to be. But then he was diagnosed with amyotrophic lateral sclerosis (ALS), a disease that shuts down the nerves that control muscles.

Ice cubes clink in a glass. Steam rises from a pot of boiling water. Solids, liquids, and gases are all around you. But what exactly are solids, liquids, and gases? And how do you tell them apart? Listen to this audiobook to find out!
