Department of Geological Sciences

Advisor Dr. Gary Girty
Saprock is that part of the regolith in which more than 20% of the weatherable minerals are chemically or texturally altered. In the Peninsular Ranges of southern California, saprock is a ubiquitous feature of the land
3.052 Nanomechanics of Materials and Biomaterials (MIT)
This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10-9 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a ser
Mongoose Attacking an Asian Cobra
This brief video show a mongoose successfully attacking an Indian cobra. Younger students may find the video disturbing--recommended for middle school students and up. There is no commentary but there is background music.
Baboons of the Serengeti
Baboons of the Serengeti - Learn about the Baboon tribes of the Serengeti and see their ways of life in this short clip. (The clip ends abruptly.) (03:35)
20.462J Molecular Principles of Biomaterials (MIT)
This course covers the analysis and design at a molecular scale of materials used in contact with biological systems, including biotechnology and biomedical engineering. Topics include molecular interactions between bio- and synthetic molecules and surfaces; design, synthesis, and processing approaches for materials that control cell functions; and application of state-of-the-art materials science to problems in tissue engineering, drug delivery, vaccines, and cell-guiding surfaces.
End of Feudalism and Beginning of Commerce
Europe experienced radical economic and social changes between the 11th and 14th centuries. The medieval world was based on feudalism, a highly regulated and hierarchical form of society in which everyone had their place and responsibilities. The manorial system, in which lords owned the land worked by their vassals, or serfs, started to wane in the late Middle Ages with the development of nation-states. Medieval cities, dominated by the guilds that brought economic stability, became the centers
Animation: Static Electricty andWater
This video demonstrates the phenomenon of static induction. A thin thread of flowing water can detect static electricity if a charged object is approached to it. That simple object can be a balloon and it can be charged by rubbing it on a carpet. (01:48)
Fracture surface in a liquid crystalline polymer
Above their melting point, liquid crystalline polymers exhibit a mesophase within which, although able to flow and are not arranged in a crystal, they exhibit long range orientational order. This molecular alignment can be exploited to make high strength and stiffness fibres such as Kevlar, or even mouldable thermotropics such as Vectra. Molecular alignment can also be controlled by an external applied field; a property exploited in liquid crystal displays. This specimen has not had a magneti
9.12 Experimental Molecular Neurobiology (MIT)
Designed for students without previous experience in techniques of cellular and molecular biology, this class teaches basic experimental techniques in cellular and molecular neurobiology. Experimental approaches covered include tissue culture of neuronal cell lines, dissection and culture of brain cells, DNA manipulation, synaptic protein analysis, immunocytochemistry, and fluorescent microscopy.
