Documents efforts to contact and communicate with potential extraterrestrial life and interstellar space. Attempts to answer the question: Are we alone? Looks at the Drake equation, the standard for anyone seeking to find the number of planets with intelligent life in the Milky Way galaxy. Discusses the pioneering research at the Search for Extraterrestrial Intelligence Institute (SETI) based in Mountain View, California.

Dr. Ronald Evans reviews how cell receptors called PPARs regulate body weight by controlling fat burning or storage. Part of the 2004 Howard Hughes Holiday Lecture Series.
Very little in the physical world around us occurs without chemical reactions being involved. Takes an in-depth look at five common products that are in use all around us. Also, explores the chemistry behind their manufacture and/or use, including chemical equations. The products are soap, polystyrene, aluminum, paint, and car batteries.
Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
Fractals are complex, never-ending patterns created by repeating mathematical equations. A math student at MIT delves into their mysterious properties and how they can be found in technology and nature. Part of the "Science Out Loud" series.
Part of the "Chemistry in Action" series. Chemicals interacting with each other are one of the most fascinating topics in chemistry. Fireworks, burning flares, and rusting all illustrate chemical reactions. Describes the different types of reactions as well as the process of balancing chemical equations. Introduces the following terminology: chemical equations, Law of Conservation of Mass, decomposition and synthesis reactions, replacement reactions, and reaction rates.
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.

How did the universe form? Where did it come from? Where does Earth fit into the equation? This segment focuses on Earth's place in the universe. Other topics covered include the solar system, gravity, planetary experience, and stars. Part of the "Earth Science" series.
From cooking food to enjoying the warmth of a fire, chemical reactions happen every day. Students learn the major characteristics and types of chemical reactions. Additional concepts and terminology discussed include: reactants, products, physical and chemical changes, chemical equation, reaction rate, and indicators of chemical reactions.
Things really get spinning with a discussion of accelerated circular motion. The Standard Deviants explain rotational motion, which is the rotation of objects like planets. Along the way, students learn about radical radians and linear momentum. Part of the "Standard Deviants School: Physics" series.
Can we trust the robots of the future? Explores the world of artificial intelligence, taking us into labs and workshops where innovators teach robots to perceive, think, and move just like human beings.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term scalars. Part of the Science Video Vocab Series.
Play with voltage and resistance sliders and observe changes to the equation and circuit.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the scientific theory. Part of the Science Video Vocab Series.

Part of the Science Video Vocab Series.
The Standard Deviants discuss two-dimensional kinematics and motion in a plane. They also look at the role gravity plays in projectile motion and highlight some important equations for figuring out projectile motion and uniform circular motion. Part of the "Standard Deviants School: Physics" series.
Half a century ago, astronauts got on top of a really big rocket and sent a tiny little capsule on a 384,000 km trip to the moon and back. They were able to do it because a lot of extremely smart and dedicated people pushed engineering and chemistry to the limits. In this episode, host Joe Hanson travels to NASA in Houston to talk to astronaut Don Pettit about the rocket equation. Part of the "It's Okay to Be Smart" series.
The monarch butterfly migration is one of nature’s greatest events. This orange-winged wonder travels up to 4,500 km from all over North America to spend the winter hanging from oyamel fir trees in central Mexico’s mountain forests. But how does an animal with a brain the size of a sesame seed navigate to this one special place? Part of the "It's Okay to Be Smart" series.
The rate of a chemical reaction is affected by a number of factors, including temperature and the concentration of reactants at the beginning of the reaction. While the chemical equation may show reactants turning into products as a straightforward process, it is actually involved and precise. How exactly do reactants turn into products? Sometimes, the answer is as simple as two atoms bumping into each other and forming a bond. Most of the time, however, the process is much more complex. Controlling the rate of reactions has implications for a variety of applications, including drug design and corrosion prevention. Part of the series Chemistry: Challenges And Solutions.
