Take a step back to define reality as understood by the ancient Greeks. Then work your way forward through revolutionary ideas about reality proposed by Plato, Aristotle, Copernicus, Galileo, Kepler, and finally Newton, who inspired the Age of Enlightenment. Close with the Romantic backlash of the 19th century..

This program covers the important topic of the speed of sound waves in Physics. We begin by discussing how sound waves propagate through the air and how the speed of sound depends on the material through which the sound is propagating. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition...

Since its earliest days, science has been on a mission to unite disparate phenomena under the umbrella of more comprehensive theories. Follow the search for a grand unified theory (GUT) that unifies the workings of quantum forces, and a theory of everything (TOE) that quantizes gravity. One current TOE candidate is string theory..

Moment for moment, the one billion volts discharged in a typical lightning strike may be the most extreme of all weather phenomena. Watch lightning unfold in super-slow motion, and gain an appreciation for the exquisite complexity of this electrifying event.

Atoms are the bedrock of ordinary matter, but a century ago many scientists were very reluctant to accept their existence, despite growing evidence that chemical elements come in countable units. Investigate the backstory of the atomic hypothesis, and witness its triumph and the complications that ensued..

This program covers the important topic of work, heat, and PV diagrams in Physics. We begin by discussing how work and heat are related, and how the Pressure-Volume (PV) diagrams can be used to illustrate this relationship. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so...

Explains the mechanisms and principles behind everyday technology, machines, processes, and systems.

Lincoln knew that winning the war would take more than the same old strategies and maneuvers. It would require using technology to create new ways of waging war. Lincoln worked to make sure his soldiers and sailors had the best and latest hardware. By combining new tools with time-tested tactics, he helped revolutionize warfare.

"A wealth of good ideas" for using technology in education, from increasing student engagement to managing hybrid and distance learning ( Teachers College Record ). How should I use technology in my courses? What impact does technology have on student learning? Is distance learning effective? Should I give online tests and, if so, how can I be sure of the integrity of the students' work? These are some of the questions that instructors raise as technology...

One of Claude Shannon’s colleagues at Bell Labs was the brilliant scientist and brash Texan John Kelly. Explore Kelly’s insight that information is the advantage we have in betting on possible alternatives. Apply his celebrated log-optimal strategy to horse racing and stock trading..
