Weekly Calendar

April 11, Physics Table, Friday, 12:00-1:00 p.m., LDC 113 (Fireplace Room) Join the Department staff for lunch. We can meet on 3rd Olin at 11:55 for the short walk to the dinning hall or you can join us there. This will be an opportunity to meet Martha Anderson and Chris Carlson, the P123 Speakers.

April 11, P123 - What Physicists Do, Friday, 1:10-3:10 p.m., Olin 141, "Measuring Evaporation with Satellites", Martha Anderson and "Metallic Mining Regulation in Wisconsin: Protecting the Water", Chris Carlson. This week we welcome back two physics alums from the class of 1987 - Dr. Martha Anderson and Dr. Christopher Carlson. They are earth scientists from Madison, Wisconsin who are using their physics backgrounds to study environmental questions here on our home planet.

Martha Anderson, a scientist at UW-Madison in the field of "Remote Sensing", uses GOES thermal imagery to map land-surface evapotranspiration (ET; evaporation + plant transpiration) over large regions. ET is a critical boundary condition for both atmospheric models (forecasting, climate change. . .) and hydrologic models (groundwater flow, surface runoff...). Remote estimates of ET are also useful to farmers in scheduling irrigation, to biologists in assessing ecosystem health, and to govt. agencies in projecting crop yields. Martha is currently writing a proposal to NASA to routinely map ET over the Florida Everglades, as a means for monitoring impacts of wetland restoration and water management activities on local hydrologic conditions.

Christopher Carlson is a hydrogeologist with the WDNR working on metallic mining. He has been involved with the permitting process for the proposed Crandon Mine in northeastern Wisconsin since January of 1995. He is responsible for coordinating the portions of the technical review and impact assessment concerning groundwater existing conditions and modeling, mine waste geochemistry, surface water existing conditions and mitigation, mine waste facility design, and mine stability and grouting.

FYI

Number 6. Students may be interested in the article that was designated Number 6 in the Physical Review Letters' Top Ten List of the ten most-cited papers published in Physical Review Letters since its inception in 1958. Take a look at http://www.aps.org/apsnews/0303/030312.html It is a seminal background paper that is the effect which will be discussed by Savas Gider in his P123 talk "How to Make a Hard Drive" on May 2.

Sigma Xi Talk: "Plague, Polio, Measles and Smallpox: Disease Eradication and Bioterrorism". MN State Epidemiologist Dr. Harry Hull will be speaking on Wednesday, April 9, at 7 PM in Boliou 104. Dr. Hull is an MD who trained as an Epidemic Intelligence Service Officer at the Centers for Disease Control in Atlanta, Georgia. Previously he worked with the World Health Organization in both the eradication campaign for smallpox and the ongoing polio eradication campaign. This talk is open to the entire community and should be of wide interest given the recent world events.
