•Total eclipses occur every so often, affecting different parts of the world.•Some of the observed impacts of eclipses include:

•Total eclipses occur every so often, affecting different parts of the world.•Some of the observed impacts of eclipses include:

–Cats run and hide (Elona, 1914)–New York cabbies stop cursing (Bloomberg, 2001)–Planetary-averaged rainfall decreases by 10% on the day in question (Smith, 1981)

Eclipses…local effects

•A total eclipse will occur and be visible in San Jose on Feb 30, 2006.

•Theoretical work (Tran, 2003) has suggested that this will result in:

Eclipses…local effects

•A total eclipse will occur and be visible in San Jose on Feb 30, 2006.

•Theoretical work (Tran, 2003) has suggested that this will result in:

–A 45% decrease in incoming solar energy received at the surface for the day

–A cooling of the pavement outside Duncan Hall by 7.3 deg C

Eclipses…proposed study

•We propose to study the impacts of the Feb 30, 2006 eclipse as follows:

•We propose to study the impacts of the Feb 30, 2006 eclipse as follows:

–First, we will install a device to measure the incoming radiant energy.

•We propose to study the impacts of the Feb 30, 2006 eclipse as follows:

–First, we will install a device to measure the incoming radiant energy.

•Radiant energy will be measured for five consecutive days surrounding the eclipse, in order to generate appropriate statistics.

•We propose to study the impacts of the Feb 30, 2006 eclipse as follows:

–Second, we will tape thermometers to the concrete outside Duncan Hall and measure ground temperatures.

•Again, measurements will be made for five consecutive days surrounding the eclipse.

–Third, we will interview vendors at the Sharks game in order to determine the volume of diet pepsi sold at the game that night.

Eclipses…analyses

•Data gathered will be presented in graphical and statistical formats.

Eclipses…analyses

•Data gathered will be presented in graphical and statistical formats.

•Results will be compared with the predictions of Tran (2003).

Eclipses…preliminary work

•Here – you (Fall 05 class) could insert some preliminary data in the form of your plot PLUS an explanation of what is plotted PLUS a short discussion of what it means •The purpose is to show faculty that you have made a plot AND thought about it!

Eclipses…preliminary work

My early analysis suggest global cooling…the data may be contaminated by (whatever)…we will be looking at this in more detail
