The Symmetry Challenge: Physics on a Napkin

Send in your physics-on-a-napkin (or envelope or surface of choice) to enter the symmetry challenge. (Photo: Reidar Hahn, Fermilab. Drawings: Kurt Riesselmann, Fermilab.)

We've all heard the stories of great ideas first scribbled down in a bar on any convenient surface, often a cocktail napkin. We've also heard many cases of colleagues in bars asked to describe just what it is they do. Lacking a whiteboard or chalkboard to draw on, the cocktail napkin comes to the rescue again.

So here's the challenge: Describe your own physics research in 60 seconds, along with a photo, scan, or the original of a cocktail napkin with whatever scrawlings help tell your story. The explanation can be in the form of a 60-second audio or video file or up to 200 words of text. E-mail entries to symmetry or mail them care of David Harris, Communications Office, SLAC National Accelerator Center, MS 58, 2575 Sand Hill Road, Menlo Park, CA 94025.

Symmetry will send a prize to the author of the clearest, most entertaining entry and explanation and show a selection of the best in the magazine.

Quick and Healthy Groceries

The new National Heart, Lung, and Blood Institute obesity guidelines suggest using a shopping list and keeping a well-stocked kitchen for quick, healthy meals. Shop for low-fat foods and fill your kitchen cupboards with a supply of lower-calorie basics like the following:

•  Low- or no-fat dairy products

•  Light or diet margarine

•  Eggs/egg substitutes

•  Sandwich breads, bagels, pita bread, English muffins

•  Soft corn or low-fat flour tortillas

•  Low fat, low sodium crackers

•  Plain cereal, dry or cooked

•  Rice, pasta

•  White meat chicken or turkey

•  Fish and shellfish (not battered)

•  Beef: round, sirloin, chuck arm, loin and extra lean ground beef

•  Pork: leg, shoulder, tenderloin

•  Dry beans and peas

•  Fresh, frozen or canned fruits in light syrup or juice

•  Fresh, frozen or canned vegetables

•  Low- or no-fat salad dressings

•  Mustard and catsup

•  Jam, jelly, or honey

•  Herbs and spices

•  Salsa

Noon Today: An Inconvenient Truth

Come to Panofsky Auditorium today at noon for a lunchtime presentation of the slideshow "An Inconvenient Truth," based on the like-named movie, from 12:00 to 1:00 p.m. Menlo College Professor and Climate Project representative Gary Latshaw will discuss the impacts of climate change and the possible consequences of the continued use of fossil fuels around the world.

Colloquium Monday:
Green Cement

Next Monday, materials expert Brent Constantz will give an afternoon colloquium, "Sequestering Carbon Dioxide in the Built Environment: a Revolutionary Cement Technology." Constantz is the inventor on more than 60 issued U.S. patents—and many patent applications—for high-performance and novel cements used in applications from bone repair to civil construction. Constantz will discuss how carbon dioxide from power plant emissions can be sequestered into cement materials. The cement provides a two-way savings in greenhouse gas levels by both removing the carbon dioxide emitted from the power plant and displacing the carbon dioxide that usual cement production would have generated.

The colloquium will take place in Panofsky Auditorium at 4:15 p.m. and is open to the public. See the colloquium Web site for more details.
