Geobiology

The material for this course (12.007 Geobiology, Spring 2009) has been made available by the Massachusetts Institute of Technology Department of Earth, Atmospheric, and Planetary Sciences as part of the OpenCourseWare initiative. "This course introduces parallel evolution of life and the environment. Life processes are influenced by chemical and physical processes in the atmosphere, hydrosphere, cryosphere and the solid earth. In turn, life can influence chemical and physical processes on our planet. This course introduces the concept of life as a geological agent and examines the interaction between biology and the earth system during the roughly four billion years since life first appeared." The website provides lecture notes, recommended readings and assignments. The notes are available as PDF files.

Classical mechanics : a computational approach

The website for this course (12.620J Classical Mechanics: A Computational Approach, Fall 2008) has been made available by the Massachusetts Institute of Technology Department of Earth, Atmospheric, and Planetary Sciences as part of the OpenCourseWare initiative. The course covers: the Lagrangian formulation; action, variational principles, and equations of motion; Hamilton's principle; conserved quantities; rigid bodies and tops; Hamiltonian formulation and canonical equations; surfaces of section; chaos; canonical transformations and generating functions; Liouville's theorem and Poincaré integral invariants; Poincaré-Birkhoff and KAM theorems; invariant curves and cantori; nonlinear resonances; resonance overlap and transition to chaos; properties of chaotic motion. The website provides an online version of the textbook for the course, Structure and Interpretation of Classical Mechanics, written by Professors Gerald Jay Sussman and Jack Wisdom, and problem sets.

WorldWide Telescope

"The WorldWide Telescope (WWT) is a Web 2.0 visualization software environment that enables your computer to function as a virtual telescope-bringing together imagery from the best ground and space-based telescopes in the world for a seamless exploration of the universe." Users can follow guided tours or explore on their own. The telescope is provided by Microsoft Research. It can be downloaded to a PC or viewed on a Mac or a PC using a Web client and Microsoft Silverlight. A high specification PC is needed, particularly for the downloaded version.

Physics : spotlighting exceptional research

A free service from the American Physical Society (APS) which highlights exceptional papers from the "Physical Review" journals. It features expert commentaries written by active researchers who are asked to explain the results to physicists in other sub-fields. "Physics" includes essays (1000-1500 words) that focus on a single "Physical Review" paper or letter, concise review articles (3000-4000 words) that survey a particular area and look for interesting developments in that field, and synopses (200 words) which are staff-written distillations of interesting and important papers each week.

Numbers and number theory index

This section is part of the MacTutor History of Mathematics Archive at the University of St Andrews in Scotland. It provides a collection of articles on the history of the study of numbers and number theory, covering number systems in various ancient civilisations, Fermat's last theorem, perfect numbers, prime numbers, the concept of zero, pi, the Golden ratio, the number e, Pell's equation and the concept of infinity. There are links to biographies of mathematicians who contributed to the theories, and also to references to further reading

Quantum field theory

The University of Nottingham has made available this set of 14 lecture notes on quantum field theory as part of their open courseware initiative (U-NOW). The notes are aimed at third and fourth level undergraduates or postgraduates. Topics covered include second quantisation, free quantum fields, the Lehmann-Symanzik-Zimmermann (LSZ) reduction formula, free theory generating functionals, interacting theory, Feynman diagrams, momentum spaces, divergences, renormalisation and the on-shell renormalisation procedure, dimensional regularisation, coupling constants and asymptotic freedom. The notes were written by Dr Kirill Krasnov of the School of Mathematical Sciences and are licensed under a Creative Commons England and Wales Public License. They are available as PDF files and can be viewed online or downloaded

Freshwater and Marine Image Bank

"The Freshwater and Marine Image Bank is an ongoing digital collection of images related to freshwater and marine topics, in all their diversity. It includes images of fish, shellfish, and marine mammals, pictures of fish hatcheries and dams and vessels, materials related to polar exploration, regional and traditional fisheries, and limnological (freshwater) subjects. Its scope is global.

The images included in the Freshwater and Marine Image Bank were researched and scanned by the staff of the Fisheries-Oceanography Library of the University of Washington. The images were scanned in full color and saved (for the most part) in JPEG format."

World Database on Protected Areas

"The World Database on Protected Areas is a foundation dataset for conservation decision making. It contains crucial information from national governments, non-governmental organizations, academic institutions, international biodiversity convention secretariats and many others. It is used for ecological gap analysis, environmental impact analysis and is increasingly used for private sector decision making."
