Have you ever wondered why ceramics are hard and brittle while metals tend to be ductile? Why some materials conduct heat or electricity while others are insulators? Why adding just a small amount of carbon to iron results in an alloy that is so much stronger than the base metal? In this course, you will learn how a material’s properties are determined by the microstructure of the material, which is in turn determined by composition and the processing that the material has undergone.

As a participant in this course, you’ll be introduced to mathematical models formulated in terms of ordinary and partial differential equations. It has been shown that symmetries help us to better understand methods of integration of differential equations and to find new classes of integrable equations.

Learn how to identify symmetrical forms and appreciate their importance in nature, art, architecture, crystallography and technology. Understand symmetry quantitatively, recognize its role in beauty and design, and appreciate its function in our everyday life. The level of difficulty is intermediate-to-hard with a workload is 7-10 hrs/week. This MOOC is for credit and students who obtain a Verified Certificate with an overall mark of more than 60% earn 3 Academic Units (AU) that can be directed towards either an Unrestricted Elective (UE) or General Elective (GE-STS) subject at NTU. The usual NTU examination procedure requires student identification through webcam plus keystroke patterning for each assignment submission with a no-tolerance policy towards cheating. Students who are found to cheat, tamper with or falsify grades, or collude on assignments will be denied credits. It is not necessary to be enrolled at NTU to be awarded 3 AU and once received the AU remain valid 3 years. Because this is a for-credit course students must join the Signature Track stream within the first 2 week add-drop period (up to 21 August 2015, 2359 hrs) in accordance with NTU rules.
