15.965 Technology Strategy for System Design and Management (MIT)
This course provides you with a framework to understand the structure and dynamics of high-tech businesses, together with an approach for their effective strategic management. It is focused on domains in which systems are important, because either or both products are parts of larger and more complex systems, or they are comprised of systems. The domains covered include computing, communications (in particular the mobile and IP domains), consumer electronics, industrial networking, automotive, a
What goes up must come down
Falling demand for oil is not just an immediate reaction to the current financial crisis but a response to the structural impact of five years of very high oil prices, says Dr Pierre Noel, an expert in energy economics and policy, who notes that oil prices will rise again due to the cyclical nature of the business. However, Dr Noel believes that OPEC exacerbates these ups and downs by overshooting in both directions and considers the long term implications as the OPEC cartel gathers strength.
7.340 Learning and Memory: Activity-Controlled Gene Expression in the Nervous System (MIT)
The mammalian brain easily outperforms any computer. It adapts and changes constantly. Most importantly, the brain enables us to continuously learn and remember. What are the molecular mechanisms that lead to learning and memory? What are the cellular roles that activity-regulated gene products play to implement changes in the brain?How do nerve cells, their connections (synapses), and brain circuits change over time to store information? We will discuss the molecular mechanisms of neuronal plas
Douglas Melton, Harvard University: "Stem Cell Challenges in Biology and Public Policy" - April 10,
Douglas Melton will discuss the biology and public policy challenges surrounding stem cell research. The potential of human embryonic stem cells for understanding human development and finding new therapies will be presented. Dr. Melton is a cell and molecular biologist as well as an advocate of embryonic stem cell research. His research focuses on the developmental biology of the pancreas. One of the primary goals of his work is to understand how human embryonic stem cells differentiate into pa
6.002 Circuits and Electronics (MIT)
6.002 is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. At MIT, 6.002 is in the core of department subjects required for all undergraduates in EECS. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage ele
7.342 Developmental and Molecular Biology of Regeneration (MIT)
How does a regenerating animal "know" what's missing? How are stem cells or differentiated cells used to create new tissues during regeneration? In this class we will take a comparative approach to explore this fascinating problem by critically examining classic and modern scientific literature about the developmental and molecular biology of regeneration. We will learn about conserved developmental pathways that are necessary for regeneration, and we will discuss the relevance of these findings
15.988 System Dynamics Self Study (MIT)
Many books and thousands of papers cover the field of system dynamics. With all of these resources available, it can be difficult to know where to begin. The System Dynamics in Education Project at MIT put together these resources to help people sort through the vast library of books and papers on system dynamics. This course site includes a collection of papers and computer exercises entitled “Road Maps,” as well as a collection of assignments and solutions that were initially part
Virtual laboratories in Molecular and Cell Biology - Immuno-electron-microscopy
A virtual laboratory that includes immuno-gold labelling and transmission electron micrography (immuno-EM). It allows the student to study intracellular-traffic pathways of two cell-surface receptor molecules, following stimulation of the cells with their specific ligand, for different time periods. The programme first introduces the theory underlying the techniques and includes a video of EM work in a real laboratory. The student is then taken through a series of questions which requires them t
Virtual laboratories in Molecular and Cell Biology - SDS-PAGE
A protein analysis laboratory using SDS-PAGE, western-blotting and endoprotease digestion. The programme includes a section on the theory of the techniques, a video demonstration in a real laboratory, and a series of questions which guide the students through the structural analysis of model proteins (3 are included). Students go to the virtual laboratory and devise their own experiments in order to determine the molecular weight, subunit composition etc of the proteins. Results (gels and blots)
8.902 Astrophysics II (MIT)
This is the second course in a two-semester sequence on astrophysics. Topics include galactic dynamics, groups and clusters on galaxies, phenomenological cosmology, Newtonian cosmology, Roberston-Walker models, and galaxy formation.
3.185 Transport Phenomena in Materials Engineering (MIT)
This course deals with solid-state diffusion, homogeneous and heterogeneous chemical reactions, and spinodal decomposition. Topics covered include: heat conduction in solids, convective and radiative heat transfer boundary conditions; fluid dynamics, 1-D solutions to the Navier-Stokes equations, boundary layer theory, turbulent flow, and coupling with heat conduction and diffusion in fluids to calculate heat and mass transfer coefficients.
7.340 Nano-life: An Introduction to Virus Structure and Assembly (MIT)
Watson and Crick noted that the size of a viral genome was insufficient to encode a protein large enough to encapsidate it and reasoned, therefore that a virus shell must be composed of multiple, but identical subunits. Today, high resolution structures of virus capsids reveal the basis of this genetic economy as a highly symmetrical structure, much like a geodesic dome composed of protein subunits. Crystallographic structures and cryo-electron microscopy reconstructions combined with molecular
7.349 Biological Computing: At the Crossroads of Engineering and Science (MIT)
Imagine you are a salesman needing to visit 100 cities connected by a set of roads. Can you do it while stopping in each city only once? Even a supercomputer working at 1 trillion operations per second would take longer than the age of the universe to find a solution when considering each possibility in turn. In 1994, Leonard Adleman published a paper in which he described a solution, using the tools of molecular biology, for a smaller 7-city example of this problem. His paper generated enormous

Fracture surface in a liquid crystalline polymer, oriented by a magnetic field
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 polymer has been subjected to a m
Injection-moulded polystyrene (PS) case
The colours in the image are the result of birefringence and relate to the residual strain in the polystyrene. The pattern of strain is indicative of the flow of material during the injection process and it highlights the injection point (known as a 'sprue') which can also be identified by a small lump on the surface; the molecular alignment is greatest near this point. Towards the edges of the ruler and along its length, the material becomes more relaxed and as the molecular alignment falls, th
Injection-moulded polypropylene (PP) hinge
The colours in the image are the result of birefringence and relate to the residual strain in the polypropylene. The pattern of strain is indicative of the flow of material during the injection process and reveals the molecular alignment in the constriction which constitutes a hinge. The aligned molecules provide a fatigue resistant, flexible joint. A sprue which has been cut off is also visible in the top left-hand corner of the image.
