Learn the chemistry behind the visual arts, and how an understanding of art’s material properties helps preserve our cultural heritage.
How do artists create visual effects? In order to create an artistic impression, artists select materials that allow image formation, and that lend color, emphasis, shape, and size to the object created.
A scientist might follow up by asking, why those materials? What characteristics do they have that allow them to embody the artist’s intent? How durable are they? Will they maintain the same qualities, both physical and aesthetic, they had when the work left the studio?
Conservation science further notes that all materials deteriorate over time, and then asks a follow-up question: What physical interventions are possible to maintain, preserve and protect the work as the artist intended? Whatever is done to the art object, the result must be to make the work recognizable as the artist’s work or the result is a failure.
That is a key goal of this course: to understand, from a chemical point of view, how conservation protocols and the material aspects of an art work allow a better appreciation of an artwork and its creation, as well as confidence that it is the artist’s work.
These are not new problems. According to Leonardo da Vinci, the study of art should include the following topics:
- A knowledge of materials
- The chemistry of colors
- The mathematics of composition
- The laws of perspective
- The illusions of chiaroscuro
As the briefest study of Leonardo's life shows, he was clearly ahead of his time in wanting to understand the reasons for a vast array of natural and artificial phenomena. Even so, a thorough understanding of those subjects listed above still escapes us today – but, progress has been made and that progress is at once the subject matter and the goal of this course.
By introducing problems that chemical engineers are asked to solve and exploring the reasons why the enabling sciences are required to solve them, participants will gain a better understanding of the underlying disciplines supporting the work in chemical engineering.
Ce cours vous apportera une compréhension des concepts fondamentaux de la thermodynamique du point de vue de la physique, de la chimie et de l’ingénierie. Il est scindé un deux MOOCs. Dans la première partie, le Professeur J.-Ph. Ansermet de l’EPFL et son collaborateur le Dr. Sylvain Bréchet ont rassemblé en quatre leçons tous les principes fondamentaux de la thermodynamique. La deuxième partie du MOOC illustre l’approche thermodynamique par une série d’applications présentées par des spécialistes provenant de diverses institutions partenaires du réseau RESCIF.
A course that offers a scientific framework for understanding food and its impact on health and society from past to present. Eating and understanding the nuances of food has become a complicated and often confusing experience. Virtually every day brings news about some “miracle food” that we should be consuming or some "poison" we should be avoiding.
This eight-week online course provides an overview of the economy surrounding biotechnology. As a participant, you’ll learn about biorefineries, nutrients, biopolymers, bioenergy, and the cycle that takes products from biomass to world markets.
This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions.
This course is designed to cover subjects in advanced high school chemistry courses, correlating to the standard topics as established by the American Chemical Society. This course is a precursor to the Advanced Chemistry Coursera course. Areas that are covered include atomic structure, periodic trends, compounds, reactions and stoichiometry, bonding, and thermochemistry.
Learn chemical principles by examining materials with examples from energy generation and storage to emerging technologies. 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.
Discover a world built by atoms, shaped by molecules and kept running with chemical reactions! This subject is an introduction to the world of chemistry. You will learn about atoms, the building blocks of everything around us. You’ll learn about how these atoms are put together to make compounds, to make most of the materials that we use every day. We’ll have some fun looking at some common types chemical reactions and finally, we’ll use our knowledge of these chemical reactions along with a new way of quantifying the world in order to be able to make powerful predictions about quantitative chemistry.
