How do hurricanes get so big? Start off the coast of West Africa to see how this region is the perfect breeding ground for low-pressure disturbances. Chart the role of the Coriolis force, water temperature, and other factors that must coincide for these systems to grow into hurricanes threatening the U.S.
Description
This program covers the important topic of oscillations (part 3) and simple harmonic motion in Physics. We begin by discussing how oscillations arise in nature and how everyday processes such as pendulums lead to simple harmonic motion. We also discuss how this motion can be modeled by a sinusoid. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed...
Description
The genesis of tornadoes takes place under complex conditions that are still being deciphered by meteorologists who make detailed measurements from up close. Go inside a supercell thunderstorm to see a tornado being spawned. Then learn tornado safety tips and the precautions that professional storm chasers take.
85) Physics 2 Tutor (Thermodynamics, Oscillations & Waves): Learning By Example. Speed of Sound Waves
Description
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...
Description
The region downwind from the Great Lakes is famous for its lake effect snowstorms, which can total more than 200 inches of snow per year for some locations. Examine the factors behind this phenomenon as well as the mortal danger posed by blizzards, as shown by the tragic Children’s Blizzard of 1888.
Description
Trace the evolution of artificial intelligence (AI) from simple calculating machines to computers that can vanquish chess masters. Learn the distinction between weak AI, such as a chess-playing machine, and strong AI, which is a machine that has a truly human-like mind. Question whether strong AI is even possible..
Description
Apply the reality-analyzing tools you’ve learned in the course to the problem of life. Consider the close connection between life and sunlight. Then look at the startling exception to this rule: the fauna that flourish around volcanic vents in the dark ocean depths. What does this tell us about life’s origins?.
Description
Close by investigating one of the most eventful weather triggers of all: the El Nino–Southern Oscillation, which starts as a warming trend in the eastern Pacific and can lead to extreme weather throughout the world. Our detailed understanding of this once-mysterious phenomenon, as well as other extreme weather cycles, shows how far the science of meteorology has come.
92) Brain and Self
Description
What makes us distinctly human? Analyze the contributions of genetics, environmental factors, and social interaction to our effective functioning as members of the species. See how CT, MRI, and PET imaging technologies provide windows into brain structure and activity..
Description
No subject is bigger than reality itself, and nothing is more challenging to understand, since what counts as reality is undergoing continual revision and has been for centuries. For example, the matter that comprises all stars, planets, and living things turns out to be just a fraction of what actually exists. Moreover, we think that we control our actions, but data analytics can predict, with astonishing accuracy, when we will wake up, what we will...
Description
This program covers the important topic of transverse waves (part 2) in Physics. We begin by discussing how transverse waves arise in nature and conclude by learning in detail how to write down the mathematical representation of these waves. 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...
Description
This program covers the important topic of the first law of thermodynamics in Physics. We begin by discussing how this law is derived and how it is applied to practical problems in physics. 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 that the skills learned in this section...
96) Physics 2 Tutor (Thermodynamics, Oscillations & Waves): Learning By Example. Pendulums and Resonance
Description
This program covers the important topic of Pendulums and Resonance in Physics. We begin by discussing how under the right conditions a pendulum can be made to perfectly transfer energy which is known as resonance. 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 that the skills...
Description
Thanks to an ongoing revolution in the science of meteorology, we can now understand how extreme weather conditions arise, produce far more accurate forecasts, and know how to protect ourselves when dangerous conditions develop. The Science of Extreme Weather is your field guide to the worst that Earth’s atmosphere can inflict. In 24 exciting, informative, and potentially life-saving half-hour lectures aimed at weather novices and amateur forecasters...
Description
This program covers the important topic of thermometers and temperature scales in Physics. We begin by discussing the concept of temperature and various ways in which temperature can be measured. 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 that the skills learned in this...
Description
This program covers the important topic of latent heat and phase change in Physics. We begin by discussing the how adding or taking away energy from an object can cause it to change state between solid, liquid, and gas. 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 that...
