About this course


Are we alone in this universe? What new information and observations on exoplanets have we discovered?

In the past decade, astronomers have made incredible advances in the discovery of planets outside our solar system. Thirty years ago, we knew only of the planets in our own solar system. Now we know of thousands circling nearby stars.

Super-Earths and Life is a course about life on Earth, alien life, how we search for life outside of Earth, and what this teaches us about our place in the universe.

Meanwhile, biologists have gained a strong understanding of how life evolved on our own planet, all the way back to the earliest cells. We can describe how simple molecules can assemble themselves into the building blocks of life, and how those building blocks might have become the cells that make up our bodies today.

Super-Earths and Life is all about how these fields, astronomy and biology, together with geology, can help answer one of our most powerful and primal questions: are we alone?

About this course

In this course, which investigates physical transformations in food, we will be visited by world-famous chefs who use a number of different styles and techniques in their cooking. Each chef will demonstrate how he or she prepares delicious and interesting creations, and we will explore how fundamental scientific principles make them possible.

Topics will include:

  • How cooking changes food texture
  • Making emulsions and foams
  • Phase changes in cooking

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen! By following along with the recipes of the week, taking precise measurements, and making skillful observations, you will learn to think like both a chef and a scientist. This practice will prepare you for the final project, when you will design and perform an experiment to analyze a recipe of your choice from a scientific perspective.

The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?
