In 46 episodes, Phil Plait (aka The Bad Astronomer) teaches you astronomy! This course starts with the astronomical observations we can make with the naked eye and expands out to cover the solar system, stars, galaxies, and the universe itself. The content is loosely based on an introductory university-level curriculum. By the end of this course, you will be able to: * Define the components of the universe, from the planets in the Solar System to dark energy and gamma rays * Understand how astronomers collect and analyze data to study the past and current state of the universe * Explain the difference between asteroids, comets, and meteors * Contextualize observed phenomena within scientific theories about the history and physics of space, such as the Big Bang theory

In 50 episodes, Dr. Deboki Chakravarti will teach you organic chemistry. This course is based on sophomore-level college material, covering topics from Organic Chemistry I and II. It was developed with 9 reference texts and journal articles on specialized topics in organic chemistry, in particular: Organic Chemistry texts by Brown, Foote, Iverson and Ansyln (8th ed.); Clayden, Greeves and Warren (2nd ed.); McMurry (9th ed.) By the end of this course, you will be able to: * Recognize and name the major functional groups in organic compounds * Understand the influence of molecular structure and conformation on chemical properties and reactivity * Identify the possible reactions for a given organic compound and select reasonable reaction mechanisms given the reactant structure and functional groups * Sketch a mechanism for an organic reaction, showing valid arrow-pushing and formal charges * Develop and compare synthetic routes to a target molecule from a starting compound * Interpret spectra (e.g. IR, NMR, MS, UV/vis) and understand how they are used in structure determination * Connect the chemical properties of organic compounds to their real-world applications (e.g. in polymers, medicine, and biochemistry).

Masterpieces of microengineering, kinesins are motorized transport machines that move cellular materials to their correct locations in the cell so they can perform their functions. Kinesins have two feet, or "globular heads," that literally walk, one foot over another. Known as the "workhorses of the cell," kinesins can carry cargo many times their own size.

We are two sisters on a mission to demystify science with humor and relevance by creating videos, GIFs, comics, and resources. Our content is focused on high school biology (Pinky is a former high school biology teacher), though we do receive comments that some of our content is useful for intro biology courses at the college level as well. We're for anyone wanting to learn biology! We frequently remind viewers that we cannot include all of the fascinating exceptions and details in a video under 10 minutes. We like to create memorable visuals to the content, but they're not scientific illustrations. Meaning, nitrogen and carbon don't tap dance. Our illustrated cell and molecule cartoons are definitely not to scale. DNA is usually a right-handed double helix (well...there are exceptions) and it doesn't have eyes...a face...or a top hat...

Between you and the rest of the world lies an interface that makes up 16% of your physical weight. This is your skin, the largest organ in your body: laid out flat, it would cover close to 1.7 square metres of ground. But besides keeping your organs in, what is its purpose? Emma Bryce takes us into the integumentary system to find out. Lesson by Emma Bryce, animation by Augenblick Studios.

Planet Earth is this solid thing you are standing on right now. In your everyday life you don't really waste a thought about how amazing this is. A giant, ancient, hot rock. How did it come into existence and how big is it really? You will be surprised. The ground you are standing on is just a very, very small part of the big picture.

This video presents an overview of the Fourier Transform, which is one of the most important transformations in all of mathematical physics and engineering. This series will introduce the analytic theory of the Fourier Transform, along with the Fast Fourier Transform (FFT) algorithm for efficient computations. We will explore lots of applications in image compression, audio analysis, and solving partial differential equations.
