In this course, we go beyond the calculus textbook, working with practitioners in social, life and physical sciences to understand how calculus and mathematical models play a role in their work.

Through a series of case studies, you’ll learn:

  • How standardized test makers use functions to analyze the difficulty of test questions;
  • How economists model interaction of price and demand using rates of change, in a historical case of subway ridership;
  • How an x-ray is different from a CT-scan, and what this has to do with integrals;
  • How biologists use differential equation models to predict when populations will experience dramatic changes, such as extinction or outbreaks;
  • How the Lotka-Volterra predator-prey model was created to answer a biological puzzle;
  • How statisticians use functions to model data, like income distributions, and how integrals measure chance;
  • How Einstein’s Energy Equation, E=mc2 is an approximation to a more complicated equation.

With real practitioners as your guide, you’ll explore these situations in a hands-on way: looking at data and graphs, writing equations, doing calculus computations, and making educated guesses and predictions.

This course provides a unique supplement to a course in single-variable calculus. Key topics include application of derivatives, integrals and differential equations, mathematical models and parameters.

This course is for anyone who has completed or is currently taking a single-variable calculus course (differential and integral), at the high school (AP or IB) or college/university level. You will need to be familiar with the basics of derivatives, integrals, and differential equations, as well as functions involving polynomials, exponentials, and logarithms.

This is a course to learn applications of calculus to other fields, and NOT a course to learn the basics of calculus. Whether you’re a student who has just finished an introductory Calculus course or a teacher looking for more authentic examples for your classroom, there is something for you to learn here, and we hope you’ll join us!

The cell is a powerful case study to help us explore the functional logic of living systems. All organisms, from single-celled algae to complex multicellular organisms like us, are made up of cells. In this course, you will learn the how and why of biology by exploring the function of the molecular components of cells, and how these cellular components are organized in a complex hierarchy.

This course is designed to explore the fundamentals of cell biology. The overarching goal is for learners to understand, from a human-centered perspective, that cells are evolving ensembles of macromolecules that in turn form complex communities in tissues, organs, and multicellular organisms.

We will focus, in particular, on the mitochondrion, the organelle that powers the cell. In this context, we will look at the processes of cell metabolism. Finally, we will examine the F1F0 ATP synthase, the molecular machine that is responsible for the synthesis of most of the ATP that your cells require to do work. To underscore the importance of cell biology to our lives, we will address questions of development and disease and implications of science in society.

By the end of four weeks, we hope learners will have a deep intuition for the functional logic of a cell. Together we will ask how do things work within a cell, why do they work the way they do, and how are we impacted?

Join us as we explore the extraordinary and wonderfully dynamic world of the cell.

Many health complaints, such as cardiovascular disease, diabetes or joint problems seem inescapable diseases of old-age, but originate mostly from our lifestyle. A lifestyle that is largely dictated by our environment. The mismatch between our 'old' genes - our evolutionary heritage - and the 'modern' environment is the reason that we cannot resist the constant stimuli that seduce us to make unhealthy choices. Do's and don'ts cannot help us. 

This health course will take a radically different approach to showing you how to secure a lifestyle, which will keep you healthy throughout the lifespan. We have to let the environment do the work for us. By making small changes at our home, work, school or neighbourhood, healthier choices can become easier and automated.

Practical assignments will give you the skills to re-design your daily environments to promote healthy, longer lives for you and your family, colleagues and neighbours with whom you share your re-designed environments. You will learn how to create your own healthy living zone!

We will take you on excursions to Copenhagen, Denmark and to Ghent, Belgium to show you hands-on how the environment can help you live longer, healthier and happier lives!

SCOPE: To create an interactive learning module to help reinforce the concept of maintaining lab safety where hazardous materials are used in various laboratories.

Academic laboratories where hazardous materials are used are potentially dangerous places. Taking the necessary precautions to avoid unnecessary hazards is paramount for the safety of all involved.

In this course, you will learn about lab safety through an interactive game called "Don't Endanger the Owls".

The characters in the game include Wise Owl, Owlet, and the Zombie Squirrels. Owlet is the student figure and Wise Owl is Owlet’s sage advisor / professor figure.

In the game, your goal is to stop the Zombie Squirrels from spreading their Zombiegen by finding an “Anti-Zombiegen” in the lab that will counteract the effects of the Zombiegen. In order to find the Anti-Zombiegen, you will journey through three lab rooms: the biology lab, the chemistry lab and the analytical lab. Along the way, you will learn safe laboratory practices. In the end, if you follows safe laboratory practices, you will find the Anti-Zombiegen and saves the campus from the Zombiegen outbreak.

“Don’t Endanger the Owls” is a collaboration between the instructors of Rice University’s Responsible Conduct of Research Graduate Course, Rice’s Environmental Health and Safety and HyperWindows Inc.

Explore what it means to be human today by studying what it meant to be a hero in ancient Greek times.

In this introduction to ancient Greek culture and literature, learners will experience, in English translation, some of the most beautiful works of ancient Greek literature and song-making spanning over a thousand years from the 8th century BCE through the 3rd century CE: the Homeric Iliad and Odyssey; tragedies of Aeschylus, Sophocles, and Euripides; songs of Sappho and Pindar; dialogues of Plato, and On Heroes by Philostratus. All of the resources are free and designed to be equally accessible and transformative for a wide audience.

You will gain access to a supportive learning community led by Professor Gregory Nagy and his Board of Readers, who model techniques for “reading out” of ancient texts. This approach allows readers with little or even no experience in the subject matter to begin seeing this literature as an exquisite, perfected system of communication.

No previous knowledge of Greek history, literature, or language is required. This is a project for students of any age, culture, and geographic location, and its profoundly humanistic message can be easily received without previous acquaintance with Western Classical literature.

Everyone has an opinion on parenting – where babies should sleep, what they should eat, and whether parents should spank, scold, or praise. What’s more, the media often offers support for whichever opinions appear most popular at any given time. This leaves those of us who like to base our decisions on firm, provable facts feeling dizzy.

“The Science of Parenting” addresses this confusion by moving beyond the chatter and opinion surrounding parenting, and by looking directly at the science. Parenting itself is far from a science. Nevertheless, scientists have conducted thousands of studies that can help parents – or future parents – make sensible, informed decisions.

One goal of this course will be to provide a survey of important scientific findings spanning a range of topics that are central to the lives of parents: 

  • diet;
  • sleep;
  • discipline;
  • learning;
  • screen time;
  • impulse control;
  • vaccination.

We’ll also explore ongoing mysteries, like what causes autism, and why so many children are allergic to peanuts.

Perhaps more important, this course will not only dig into existing science, but will also explore the underlying nature of parenting science itself. Often, scientists measure correlations: they ask how different parenting practices are related to different behaviors in children. But the claims they make from correlational data are often much, much stronger. For example, from correlational data, scientists often claim that parents cause the behaviors of their kids. This course will show how this type of error – common in the scientific literature – can explain a significant amount of the confusion present in the media and general public. We will discuss how to avoid the same error when evaluating science, and how to use the sum of available evidence to inform decision making.

The course’s instructor, David Barner, is a leading authority on cognitive development. He is joined by leading experts on behavior genetics, vaccination, autism, lying, and spanking, as well as by real live parents who try to use science to inform their decisions. This class is suitable not only for parents, future parents, and grandparents, but also for professionals interested in health care, social work, and early childhood education who want to increase their knowledge and analysis skills.
