Roemer first proved that light has a finite speed by timing Io's eclipses and emergences, revealing a cumulative delay over orbits corresponding to about 220 million meters per second.
Trace how Alessandro Volta created the first battery from early electricity work and the animal electricity debate, using a zinc-silver pile with an electrolyte to form anode, cathode, and discharge.
Explore how the Doppler effect changes perceived pitch as ambulance sirens approach and recede, due to shifting frequencies and wavelengths of sound waves.
Explore how Maxwell linked electric, magnetic, and light waves into one theory and how Hertz experimentally confirmed electromagnetic waves, laying the groundwork for radio and wireless communication.
Pioneering serum therapy, researchers Behring and Kitasato immunized animals to produce antitoxins against diphtheria and tetanus, demonstrating effectiveness in early human trials.
Explore the discovery and impact of radioactivity, tracing how polonium and radium emerged from uranium research, led by Marie and Pierre Curie, and their Nobel Prize legacy.
Explore how classical conditioning links neutral stimuli like a bell or lab coat to unconditioned stimuli such as food, triggering conditioned salivation in dogs and humans.
Are you a science junkie? Are you curious about how things work? Do you like learning about scientific discoveries which helped change the world?
If yes, then this course is for you!
Do you know when the circumference of the earth was first calculated? This was over 2000 years ago using just an obelisk, the shadows cast by the mid day sun and some basic trigonometry.
Do you know that in the Age of Sail, ships that sailed with 100s of men on long voyages, often returned with just a few sailors? The rest were struck down by a mysterious and painful illness which never seemed to strike on land.
Do you that bees which you see waggling around on their hive, dance for a specific purpose? Bees use their waggle dance as a form of communication to tell other bees where food and nesting sites are located.
A complete, first principles discussion of some of the most important scientific experiments conducted over the last 2000 years. Understand what the experiment was, why it was important and who first demonstrated it,
