"Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike"--

"What bit of science do the Imagineers turn to when they want to make a splash? Fluids! In this DVD, the Imagineers demonstrate how they use fluids to their advantage in constructing rides and attractions like Grizzly River Run and The Seas with Nemo and Friends. Students will learn that a fluid is any substance that flows or moves easily due to its molecular make-up. They will also discover how fluid dynamics help us learn how fluids move and behave...

In the new 2021 high-definition program, learn all about the states of matter - solid, liquid and gas. What are reversible and irreversible change? What are physical and chemical changes? These questions and more are covered in depth with detailed graphics, engaging examples and exciting video. On-screen, multiple-choice reviews at the end of each segment reinforce important points and make learning fun.

On July 4, 2012, scientists at the giant atom smashing facility at CERN announced the discovery of a subatomic particle that seems like a tantalizingly close match to the elusive Higgs Boson, thought to be responsible for giving all the stuff in the universe its mass. Now CERN's scientists are preparing to restart the history-making collider, hoping to find the next great discovery.

Dropping boulders off a tower makes gravel for the Mammoth Island roads, but lifting the boulders up to the top of the tower is difficult and dangerous. A young Mammoth Islander suggests that rolling boulders up a ramp would be easier than hauling them up a tower.

Amanda, a divorced photographer, finds herself bored and uninspired by everyday events. Suddenly, she envisions herself in a fantasy world with strange creatures and quirky representations of real-life subcellular particles. Interjected by discussions with mystics and scientists, she questions what reality is and searches for a redefinition of her perception of life. Explores the links between quantum mechanics, neurobiology, human consciousness,...

With our time on Earth coming to an end, a team of explorers undertakes the most important mission in human history; traveling beyond this galaxy to discover whether mankind has a future among the stars.

Two young Mammoth Islanders enlist the help of a visiting inventor to design a machine that will make the rides at the amusement park much more exciting. After observing the power in the expanding steam of a tea kettle, they decide to build a steam engine that would convert heat energy to mechanical energy that will power everything from spinning cotton candy to powering roller coasters.

"What is the force that puts the thrill in thrill rides? Gravity, of course! One of the biggest challenges for Imagineers in designing theme park attractions, like Disney's Rockin' Roller Coaster and The Twilight Zone Tower of Terror, is figuring out the best way to work with-and sometimes against-gravity's constant 1G force. Learn to define gravity and explain the relationship between gravity, mass, and distance. Apply an understanding of forces...
