Topics include conformation and molecular dimensions of polymer chains in solutions, melts, blends, and block copolymers; an examination of the structure of glassy, crystalline, and rubbery elastic states of polymers; thermodynamics of polymer solutions, blends, crystallization; liquid crystallinity, microphase separation, and self-assembled organic-inorganic nanocomposites. Case studies include relationships between structure and function in technologically important polymeric systems."

This activity shows students that heterogeneous mixtures can be separated by physical means, and that when separated, all the parts will equal the whole.

A class demonstration gives the students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. Students discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of mixtures and solutions.

They use a fluorescent compound as the dye to track through a series of dilution steps. They observe how the changing color intensity, or saturation, of each subsequent solution. They also keep a running calculation of the concentration dye in each serial dilution. Finally, using a UV lamp, they investigate whether the fluorescent dye can be detected after it disappears from view under normal lighting conditions. Matthew D.

Students systematically dilute solutions of food coloring with pure water. They observe how the color intensity, or saturation, of each subsequent solution changes. They also keep a running calculation of the concentration of drops per ml water. They apply what they learn to discussions of biomedical engineers working with cells. Matthew D. Cathell Mathematics and Statistics Science and Technology 2009-11-02T09:52:37 Course Related Materials http://www.oercommons.org/courses/go-with-the-flow Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.

Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are discussed.

The class uses examples from the materials science and engineering core courses (3.012 and 3.014) to introduce mathematical concepts and materials-related problem solving skills. Topics include linear algebra and orthonormal basis, eigenvalues and eigenvectors, quadratic forms, tensor operations, symmetry operations, calculus of several variables, introduction to complex analysis, ordinary and partial differential equations, theory of distributions, and fourier analysis.

It is basically the idea that the mysterious phenomena underlying most of the most challenging problems in modern / ultramodern science / philosophy are, in fact, multiple aspects of a singular structure, which the NSTP (Non – Spatial Thinking Process) theory (a major component of superultramodern science / philosophy) is the unique theoretical representation of. The NSTP theory thus unifies and demystifies the phenomena, and solves the problems. The first part of this article presents the solutions to two of the problems viz. Zeno’s paradoxes and the problem of quantum non-locality. The second part states the remaining problems. And the third, and the last, part states some other challenging problems, solvable with the NSTP theory, which are not directly connected to the aforementioned structure.

Asking students to write these statements about a text will enable students to read the text closely and will ensure that they understand the structure of a problem/solution text.
