This issue of 'Shadow of A Doubt' from the National Capital Area Skeptics (NCAS) focuses on promoting critical thinking and scientific understanding through upcoming events and discussions.

Featured Lecture: Positively Skeptical: A Way of Knowing

Speaker: Prof. Marvin Zelkowitz
Affiliation: Professor of Computer Science at the University of Maryland in College Park.
Date & Time: Saturday, March 18, 2006, 2 - 4 pm
Location: Silver Spring Library, 8901 Colesville Road, Silver Spring, MD 20910

Prof. Zelkowitz, a long-time member and past president of NCAS, will explore the concept of skepticism, tracing its roots from ancient Greece through the Renaissance to the present day. The lecture aims to define skepticism beyond mere cynicism, highlighting its importance for personal well-being and critical evaluation of information. It will address why one should question beliefs and examine the credibility of evidence. The talk will also touch upon current skeptical organizations and NCAS's role within this movement. The timing is noted as particularly relevant due to the ongoing controversy between Intelligent Design and Evolution, and the celebration of Charles Darwin's birthday.

• Dark Matter (11:15 a.m. - 12:30 p.m.): Examining its existence, effects on galactic clusters, related theories in particle physics and supersymmetry, and potential detection methods.
• Lunch (12:30 p.m. - 2 p.m.): Participants are expected to provide their own lunch.
• Dark Energy (2 p.m. - 3:15 p.m.): Exploring Einstein's theories, the discovery of the accelerating universe, and new developments in understanding dark energy.
• Or, Maybe We Don't Understand Gravity? (3:30 p.m. - 4:30 p.m.): Presenting alternative theories of gravity that do not rely on dark matter or dark energy.

Mario Livio is a senior astronomer at the Space Telescope Science Institute. Ticket prices vary for general admission, RAP members, and senior members. Contact information for registration is provided.

Recurring Themes and Editorial Stance

The recurring theme throughout this issue is the promotion of scientific skepticism and critical thinking. The NCAS positions itself as an organization that encourages evidence-based reasoning and challenges pseudoscientific claims. The editorial stance is clearly in favor of scientific inquiry, rationalism, and the rigorous examination of evidence, as exemplified by the featured lecture and seminar topics. The organization actively seeks to engage the public in these discussions and encourages member participation in its activities and outreach efforts.
