OSU Science Pub: Life on other planets
Speakers: Martin Fisk and Rick Colwell, OSU College of Oceanic and Atmospheric Sciences A mere 20 light-years from Earth — just down the block by galactic standards — a planet orbits a red dwarf star in what one scientist has called a "mini-version of our own solar system." The star is known as Gliese 581, and this planet, one of six in orbit, appears to be the right size and distance from its sun to be hospitable for life. Many s...cientists believe that life elsewhere in the Milky Way Gal

Readings in the History of Aesthetics
Anyone with connection to the Internet has access to a vast number of philosophical documents via online etexts. Fortunately, quite a bit of the best work in philosophy is in the public domain, and a few of these readings provide a convenient access for almost anyone seeking information and help in the history of aesthetics. However, many of the historically significant writings in aesthetics are not presently available on the Internet, and this open source text helps somewhat to remedy that nee

Peer-to-Peer Copying
Most Internet content today is "served" from a central system that takes requests from a user's "client." Typically, the user asks for access to information or other data; the requested content is then "pushed" from the central system to the user. In this model, the various visitors to a given web site do not interact. By contrast, peer-to-peer technology (commonly known as "P2P") creates conversations among individual personal computers (PCs). In this respect, P2P systems resemble an affili

Freedom of Expression on the Internet
The Internet offers extraordinary opportunities for "speakers," broadly defined. Political candidates, cultural critics, corporate gadflies -- anyone who wants to express an opinion about anything -- can make their thoughts available to a world-wide audience far more easily than has ever been possible before. A large and growing group of Internet participants have seized that opportunity. Some observers find the resultant outpouring of speech exhilarating. They see in it nothing less than the re

Access to the Internet
Using the Internet depends, in the first instance, on access to the network. The initial emergence of "the Internet" in the early 1990s, from the increasing connectivity of a series of university and government networks alongside private services like America Online, Prodigy, and CompuServe, occurred almost entirely across slow dial-up modem connections over telephone wires. Sufficient for email, Usenet news groups, transferring relatively small files, and later viewing simple web pages, slow tr

California Fires MODIS imagery and TOMS Aerosols from October 2003
This animation sequences through the MODIS imagery of the devastating Californian fires from October 23, 2003 through October 29, 2003. Then the animation resets to October 23, 2003 and zooms out to see the TOMS aerosol sequence. It clearly shows that the California fires had an impact on air quality as far east as Maine.

GLOBE 1987 Global Patterns Poster
The purpose of the ESS activities associated with the GLOBE 1987 Global Patterns Poster is to help students understand the broader global context for local GLOBE measurements. Students discover patterns in global maps of environmental data, interpret those patterns, and draw conclusions and make predictions based on them; communicate those interpretations and predictions; and develop an understanding that the components of the Earth system interact. By completing this activity, students will gai

Elementary GLOBE: We're All Connected
A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. One of the "big ideas" in Earth system science is the notion of interaction among parts of the Earth system. In the Elementary GLOBE book All About Earth: Our World on Stage, the children in Ms. Patel's class discuss instances of how the four major spheres of Earth's system interact. They symbolize these interactions by using large arrows to link the system components: air, water, soil, living

Yet Another Calculus Text
I intend this book to be, firstly, a introduction to calculus based on the hyperreal number system. In other words, I will use infinitesimal and infinite numbers freely. Just as most beginning calculus books provide no logical justification for the real number system, I will provide none for the hyperreals. The reader interested in questions of foundations should consult books such as Abraham Robinson's Non-standard Analysis or Robert Goldblatt's Lectures on the Hyperreals. Secondly, I have aime

But What Does It Mean? Symbolism in Artwork
In this elementary-level lesson, students will learn about the importance of symbolism and prior knowledge in the interpretation of artwork. After defining symbolism and seeing a simple example, students will analyze and identify symbols in The Artist in His Museum, 1822, a self-portrait created by Charles Willson Peale in 1822. They will then be given additional factual information about Peale's life and be asked to revisit their initial perceptions and confirm or revise their thoughts. Finally
