Space Weather, Earthly Effects

From the physics standpoint, space weather is the ultimate challenge for our understanding of the heliophysics system - the chain of interacting complex domains ranging from the Sun to the upper mantle of the Earth. Predicting the dynamic evolution of the system is the test for our capacity to capture the key physical processes operating in these domains. For more information.




The Lectures, which are the centerpiece of all Philosophical Society of Washington meetings, are selected to appeal to those with a general interest in science and do not require a specialized knowledge of the subject. They always contain information that is current, explanations that are understandable and a few controversial issues to be challenged by a critical listener. The series is designed as much as possible to include a wide range of disciplines.

The meetings are open to the public, free, and no reservations are required. Dress is informal. Meetings are followed by lively conversation. All must exit the Cosmos Club at 10:30 p.m. Conversations are continued at another location. Please note, there is no parking at the Cosmos Club.

Meeting Location

The John Wesley Powell Auditorium is adjacent to the Cosmos Club, 2170 Florida Avenue NW, Washington DC 20008. Entrance is through the club gate, the first right-hand entrance on Florida Avenue north of the intersection with Massachusetts Avenue NW. The auditorium entrance is to the left of the gate.

The Cosmos Club is within walking distance of the DuPont Circle Metro stop (Q Street exit), the Connecticut Avenue bus routes (L2, L4), and the Massachusetts Avenue bus routes (N2, N4).
