During each week of this course, chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Inspired by such cooking mastery, the Harvard team will then explain the science behind the recipe.
Topics will include:
- How molecules influence flavor
- The role of heat in cooking
- Diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià.
You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen. By following along with the engaging recipe of the week, taking precise measurements, and making skillful observations, you will learn to think like both a cook and a scientist. 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?
HarvardX requires individuals who enroll in its courses on edX to abide by the terms of the edX honor code : https://www.edx.org/edx-terms-service. HarvardX will take appropriate corrective action in response to violations of the edX honor code, which may include dismissal from the HarvardX course; revocation of any certificates received for the HarvardX course; or other remedies as circumstances warrant. No refunds will be issued in the case of corrective action for such violations. Enrollees who are taking HarvardX courses as part of another program will also be governed by the academic policies of those programs.
HarvardX pursues the science of learning. By registering as an online learner in an HX course, you will also participate in research about learning. Read our research statement: http://harvardx.harvard.edu/research-statement to learn more.
Harvard University and HarvardX are committed to maintaining a safe and healthy educational and work environment in which no member of the community is excluded from participation in, denied the benefits of, or subjected to discrimination or harassment in our program. All members of the HarvardX community are expected to abide by Harvard policies on nondiscrimination, including sexual harassment, and the edX Terms of Service. If you have any questions or concerns, please contact email@example.com and/or report your experience through the edX contact form: https://www.edx.org/contact-us.
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).
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.
