This video lesson will present Gravity Assist, or what is wrongly referred to as the gravitational slingshot. Gravity assist is a maneuver performed by interplanetary spacecraft to travel farther on less fuel. It is a classic exercise in Newtonian mechanics. [37:49]

This video lesson highlights how science can be learned from daily life experiences. It emphasizes the ways in which simple laws of physics can be understood from personal observations and experiences, and in fact it demonstrates that we use these laws as if they were built into our instincts. The video also introduces Newton's laws of motion. [41:37]

This video lesson uses the technique of induction to show students how to analyze a seemingly random occurrence in order to understand it through the development of a mathematical model. [41:24]

A university-level course in basic observational procedures in astronomy. Covers how to use a telescope, and includes lecture notes.

The goal of this lesson is for students to understand just how many particles Avogadro's Number truly represents, or, how big a mole really is. [19:02]

This video is the second lesson in the How Cold Is Cold? BLOSSOMS series and examines the properties of materials under low temperature conditions. [32:19]

This video lesson is part of a two-part series and introduces the concept of temperature. Temperature can be a challenging concept to convey since our perception is tied to words that are relative to our own experience, which varies quite a lot. [19:18]

The objective of this lesson is to introduce students to one of the most important issues affecting human life and health in the 21st century, the application of modern biotechnology to the problems of environmental pollution. [22:51] (English Subtitles)

By viewing high-speed videos of raindrops hitting mosquitos, learn how insects are able to fly in the rain by calculating the impact forces of raindrops on flying mosquitoes.

This video lesson introduces students to the concept of size. It looks at how to classify objects based on their size and how the size of an object affects its properties and behavior. In our world, we have many different sizes - starting from quarks and subatomic particles, to atoms and molecules, all the way to aggregates and huge objects like ourselves, and beyond to larger bodies like mountains, planets, stars, galaxies and even to the whole universe. [42:13]

Students learn how scientists in several fields work together to take part in the steps of anti-cancer drug discovery.

An open course in intermediate microeconomics for those students needing a challenge. Includes list of suggested readings, lecture notes, assignments, exams, and study materials.

The text for the first fourteen books of Ovid's Metamorphoses. Includes links to share recommended related sites among users.

Historically chronicled, the environment's effects on people and people's effects on the environment are emphasized and brought to life through the many materials suggested here.

College-level electrical engineering course highlighting numerical analysis for engineers. This course introduces students to the formulation, methodology, and techniques for numerical solution of engineering problems. Course features include suggested readings, lecture notes, assignment problems, and exams with solutions.

This course surveys questions about human behavior and mental life ranging from how you see to why you fall in love. The great controversies: nature and nurture, free will, consciousness, human differences, self and society. Students are exposed to the range of theoretical perspectives including biological, evolutionary, cognitive, and psychoanalytic. One of the best aspects of Psychology is that you are the subject matter. This makes it possible to do many demonstrations in lecture that allow you to experience the topic under study. Lectures work in tandem with the textbook. The course breaks into small recitations sections to allow discussion, oral presentations, and individual contact with instructors.

This learning video addresses a particular problem of selection bias, a statistical bias in which there is an error in choosing the individuals or groups to make broader inferences. Rather than delve into this broad topic via formal statistics, we investigate how it may appear in our everyday lives, sometimes distorting our perceptions of people, places and events, unless we are careful.

Could a Tyrannosaurus be created in a modern-day lab? Join paleontologist, Jack Horner, in using protein sequencing to find the closest relative to the T-Rex, and then hypothetically re-creating a specimen in the lab.

This lesson presents the basics of aerodynamics by using kite flying as an example, i.e., forces acting on a flying object. [39:36]

An introductory course in labor economics from MIT. Emphasizes applied microeconomics and empirical analysis. Includes suggested readings, assignments, and exams.
