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). 

Introduction to Solid State Chemistry is a first-year single-semester college course on the principles of chemistry. This unique and popular course satisfies MIT's general chemistry degree requirement, with an emphasis on solid-state materials and their application to engineering systems.

An introduction to current concepts of how cellular molecules come together to form systems, how these systems exhibit emergent properties, and how these properties are used to make cellular decisions.

The human cardiovascular system is made up of the heart, blood vessels and blood supply. These act as one system to supply vital oxygen, nutrients, and hormones to tissues and remove carbon dioxide and metabolic waste products. This system also plays a central role in stabilizing body temperature and pH levels, as well as maintaining homeostasis. In this free online cardiovascular anatomy and physiology course, the learner will explore the structure and functions of the cardiovascular system. The course explains the composition of blood and provides an overview of how blood is used for transport and energy mobilization. It also outlines how the blood responds to haemorrhage and is involved in maintaining the correct body temperature. The course then examines blood vessels, explaining the function and location of arteries, veins and capillaries. Finally, it covers the anatomy of the heart, describing the structure of the chambers of the heart, the cardiac valves and the heart walls. It also describes the pericardium, the NAVL and the fibrous skeleton of the heart. This free online cardiovascular anatomy and physiology course will be of great interest to professionals in the health care sector who would like a greater knowledge and understanding of the human cardiovascular system. Students of medicine and biology who would like to study the structure and function of the heart, blood vessels and blood supply, which make up this very important anatomical system, will also find this course of great help.<br />

The human body cannot generate energy itself and so must obtain it from external sources. Energy from the sun is captured by plants, which in turn are eaten by animals. We humans use these plants and animals as food sources but, in order to obtain the energy we require from them, our food must be broken down into smaller molecules that the body can process. This is accomplished by a complex series of organs known as the digestive system. This free online human physiology course provides a clear introduction to the human digestive system. In this course you will learn how energy is obtained from food and be introduced to the different food types and vitamins. The course looks at the stages involved in ingestion and swallowing, describing how the stomach is designed for food storage and the initial processing of food. How the small and large intestines are structured to facilitate the digestion and absorption of nutrients is also examined. The course also provides an overview of the elimination of the waste products of digestion from the body. It outlines the special roles played by the liver and pancreas in the secretion of digestive enzymes. The mechanisms used by the digestive system to protect the body from infection are covered. This includes looking at the tonsils and other lymphoid tissue in the small and large intestine and explaining how the mammary gland protects the breastfeeding baby from infection. This free online human physiology course will be of great interest to healthcare professionals who would like a greater understanding of the human digestive system and its importance in human physiology, and to students of biology, medicine and nursing who would like to gain a greater knowledge and understanding of the structure and function of the human digestive system. <br />

Discover how to integrate nature’s value into decisions affecting the environment and human well-being.

Step into the world of Tissue Engineering, a rapidly expanding field of applied biology aiming to create artificial organs for transplantation, basic research, or drug development.

Water is essential for life on Earth and of crucial importance for society. Water also plays a major role in affecting climate. Its natural cycle, from ocean to atmosphere by evaporation, then by precipitation back to land returning via rivers and aquifers to the oceans, has a decisive impact on regional and global climate patterns.

For students of engineering, climate science and environmental studies, this course offers a first introduction to the physics of water systems and their role in climate. In addition, we show you the state-of-the-art engineering interventions that can be applied to water systems. These can improve coastal safety and increase the availability of water supplies worldwide.

The course welcomes students from all over the globe, so we actively encourage discussion of water and climate issues you may experience in your location, now and in the coming decades.

After taking this course, you will be able to:

• Understand the different processes at play in the global water cycle.
• Identify and describe the flows of water and sand in different riverine, coastal and ocean systems.
• Identify mechanisms of climate change and explain the interplay between climate change, sea level, clouds, rainfall and future weather.
• Explain why, when and which engineering interventions are needed in rivers, coastal and urban environments.
• Explain why water for food and water for cities are the main challenges in water management and propose solutions.
• Explain and confront the challenges in better understanding and adapting to the impact of climate change on water over the coming 50 years.

The course consists of knowledge clips, movies, exercises, and exam assignments. There are opportunities to discuss course materials with your fellow students and the Course Team through our online forum. We also provide interactive feedback video sessions in which the lecturers discuss issues raised by students.

Delft University of Technology (TU Delft) has a unique reputation when it comes to water and climate, with faculty experts in the fields of climate research, water management and hydraulic engineering. The course introduces you to many aspects of water and climate: from the micro scale of raindrops to the macro scale of oceans, and from understanding the physics of the different water systems to practical engineering solutions that may help societies adapt to the present and future impacts of climate change on water.

Together with the courses "Drinking water treatment" and "Urban Sewage Treatment" this course forms the Water XSeries, from the Faculty of Civil Engineering and Geosciences at TU Delft.

This course is an investigation to distinguish episodic memory, which is memory of personal events, from semantic memory, which is general knowledge independent of time and place.

Use your kitchen as a laboratory to learn about chemistry using everyday chemicals.

9.63 teaches principles of experimental methods in human perception and cognition, including design and statistical analysis. The course combines lectures and hands-on experimental exercises and requires an independent experimental project. Some experience in programming is desirable. To foster improved writing and presentation skills in conducting and critiquing research in cognitive science, students are required to provide reports and give oral presentations of three team experiments. A fourth individually conducted experiment includes a proposal with revision, and concluding written and oral reports.
