Science Café of Olympia meets each month on the second Tuesday at Orca Books. It provides an informal atmosphere where people with and without scientific background can meet to deepen their understanding of interesting topics in science and technology. After a presentation by an expert in the field, the meetings are opened for discussion. This month, a big brain will discuss cutting edge electron microscopy. The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail, like our imagination in creating this blurb.

SCIENCE CAFE, 7 p.m., Orca Books, 500 E. Fourth Ave., Olympia, free admission, 360.352.0123
