This course introduces what we already know, and what we are still discovering, about the form and function of the human brain.

In BIO101 [1], you were introduced to biology on a microscopic scale when you learned about the functions of molecules, genes, and cells.  In this course, you will learn about biological changes that happen on a very large scale, across entire populations of organisms and over the course of millions of years, in the form of evolution and ecology.  Evolution, the process by which different species of organisms have developed and diversified from their evolutionary forbears, has been a central theme in the field of biology ever since Darwin first published his theories about it.  Mounting evidence from many different branches of science all point to the fact that species have experienced a gradual but definite physical change.  In this course, we will learn about evolution and theories that stem from evolution. We will also learn about ecology, the study of the interactions between different types of organisms and their surroundings.  Changes in surroundings will force organisms to adapt and changeoften…

This course is designed to introduce you to the study of Calculus.  You will learn concrete applications of how calculus is used and, more importantly, why it works.  Calculus is not a new discipline; it has been around since the days of Archimedes.  However, Isaac Newton and Gottfried Leibniz, two 17th-century European mathematicians concurrently working on the same intellectual discovery hundreds of miles apart, were responsible for developing the field as we know it today.  This brings us to our first question, what is today's Calculus?  In its simplest terms, calculus is the study of functions, rates of change, and continuity.  While you may have cultivated a basic understanding of functions in previous math courses, in this course you will come to a more advanced understanding of their complexity, learning to take a closer look at their behaviors and nuances. In this course, we will address three major topics: limits, derivatives, and integrals, as well as study their respective foundations and a…

In this course, you will look at the properties behind the basic concepts of probability and statistics and focus on applications of statistical knowledge.  You will learn about how statistics and probability work together.  The subject of statistics involves the study of methods for collecting, summarizing, and interpreting data.  Statistics formalizes the process of making decisions, and this course is designed to help you use statistical literacy to make better decisions.  Note that this course has applications for the natural sciences, economics, computer science, finance, psychology, sociology, criminology, and many other fields. We read data in articles and reports every day.  After finishing this course, you should be comfortable evaluating an author's use of data.  You will be able to extract information from articles and display that information effectively.  You will also be able to understand the basics of how to draw statistical conclusions. This course will begin with descriptive statistic…

This chemistry survey is designed to introduce students to the world of chemistry.  The principles of chemistry were first identified, studied, and applied by ancient Egyptians in order to extract metal from ores, make alcoholic beverages, glaze pottery, turn fat into soap, and much more.  What began as a quest to build better weapons or create potions capable of ensuring everlasting life has since become the foundation of modern science.  Take a look around you: chemistry makes up almost everything you touch, see, and feel, from the shampoo you used this morning to the plastic container that holds your lunch.  In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior.  We will use this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter.

In this second semester course, we will cover a wide-ranging field of topics, learning everything from the equation that made Einstein famous to why you can’t replace a dead car battery with a household battery. In General Chemistry I (CHEM101 [1]), we studied the basic tools you need to explore different fields in chemistry, such as stoichiometry and thermodynamics.  This second-semester course will cover several of the tools needed to study chemistry at a more advanced level.  We will identify the factors that affect the speed of a reaction, learn how an atom bomb works on a chemical level, and discover how chemistry powers a light bulb.  Topics in advanced organic and inorganic chemistry courses will build upon what you learn in this class.  We will end with discussion of organic chemistry, a topic that is as important to biology as it is to chemistry.

Organic chemistry is a branch of chemistry that focuses on a single element: carbon!  Carbon bonds strongly with other carbon atoms and with other elements, forming numerous chain and ring structures.  As a result, there are millions of distinct carbon compounds known and classified.  The vast majority of the molecules that contain carbon are considered organic molecules, with few debatable exceptions such as carbon nanotubes, diamonds, carbonate ions, and carbon dioxide.  Carbon is central to the existence of life as it is an essential component of nucleic acids (DNA and RNA), sugars, lipids, and proteins.  A well-rounded student of science must take courses in organic chemistry to understand its application to various topics, such as the study of polymers (plastics and other materials), hydrocarbons, pharmaceuticals, molecular biology, biochemistry, and other life sciences. In the first semester of organic chemistry, you will learn the basic concepts needed to understand the three-dimensional structu…

This course is a continuation of CHEM103 [1]: Organic Chemistry I.  As you progress through the units below, you will continue to learn the different chemical reactions characteristic of each family of organic compounds.  We will focus on four most important classes of reactions: electrophilic substitution at aromatic rings, nucleophilic addition at carbonyl compounds, hydrolysis of carboxylic acids, and carbon-carbon bond formation using enolates.  The enolate portion of this course will cover the reactivity of functional groups. We will also look at synthetic strategies for making simple, small organic molecules, using the knowledge of organic chemistry accumulated thus far.  At the end of this course, you will possess the tools you need to plan the synthesis of fairly complicated molecules, like those used in pharmaceutics.  From the perspective of a synthetic organic chemist, the two most challenging aspects of synthesizing drug molecules are the incorporation of  "molecular rings" (rings of 5, 6,…

Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond  closely to actual observations.  Given this definition, the story behind everything in the universe is  one of physics.  In practice,  the field of physics is more often limited to the discovery and refinement of the basic laws that underlie the behavior of matter and energy.  While biology is founded upon physics, in practice, the study of biology generally assumes that the present understanding of physical laws is accurate.  Chemistry is more closely dependent on physics and   assumes that physical laws provide accurate predictions.  Engineering, for the most part, is applied physics. In this course, we will study physics from the ground up, learning the basic principles of physical laws, their application to the behavior of objects, and the use of the scientific method in driving advances in this knowledge.  This first course o…
