This first-year University chemistry course explores the basic principles of the chemical bond by studying the properties of solids. Properties such as stiffness, electrical conductivity, thermal expansion, strength, and optical properties are the vehicle by which you can learn a great deal of practical chemistry.
You will see how experts use their knowledge of trends in the periodic table to predict the properties of materials. 3.091x is an engineering course so there is an emphasis on applications and how materials are used. The on-campus version of the course has been taught for over forty years and is one of the largest classes at MIT.
This course will cover the relationship between electronic structure, chemical bonding, and atomic order, and characterization of atomic arrangements in crystalline and amorphous solids: metals, ceramics, semiconductors, and polymers (including proteins). There will be topical coverage of organic chemistry, solution chemistry, acid-base equilibria, electrochemistry, biochemistry, chemical kinetics, diffusion, and phase diagrams. Examples will be drawn from industrial practice (including the environmental impact of chemical processes), from energy generation and storage (e.g., batteries and fuel cells), and from emerging technologies (e.g., photonic and biomedical devices).

You will become intimately acquainted with the operational principles of neuronal “life-ware” (synapses, neurons and the networks that they form) as well as with recent ideas about how the dynamics of these networks generate the “neuronal code.” As an aperitif we will highlight present brain-excitements and for dessert we will discuss the future of brain research

Each mammalian cell has the same genes, yet performs distinct functions. This is achieved by epigenetic control of gene expression; the switching on and switching off of genes. This course will cover the principles of epigenetic control of gene expression, how epigenetic control contributes to cellular differentiation and development, and how it goes wrong in disease.

This course will introduce you to some of the science behind food preparation, cooking methods, and generally, the enjoyment of food. The ultimate goal is to inspire you to apply scientific principles in your everyday cooking, including the principles of manipulating the human perception of food.
Each of our cells contains nearly identical copies of our genome, which provides instructions that allow us to develop and function. This course serves as an introduction to the main laboratory and theoretical aspects of genomics and is divided into themes: genomes, genetics, functional genomics, systems biology, single cell approaches, proteomics, and applications.
