January 28 th is Kathleen Yardley Lonsdale's birthday. Lonsdale was a leading figure in the field of crystallography. She began her work in the laboratory of William Bragg developing the techniques of x-ray crystallography. Her early work centered on simple molecules and branched into more complex organic compounds. She was the first to verify the shape of the benzene molecule. She showed the six carbon atoms that make up benzene were laid out in a flat hexagon. Her later research involved x-ray crystallography of pharmaceuticals and other biochemical compounds. The Royal Society elected her as their first female Fellow in 1945 to honor her work.

I'm talking about making a positive impression... there are lots of ways you can make a negative impression on a science fair judge. If that's your goal, turn in a poster with breakfast stains on it, which describes a project totally unrelated to science that you started on the way to school that day. On the other hand, if you are doing a science fair project and want to win an award or get a good grade, here are the types of things a science fair judge.
