An electron may not be exactly what has been thought since its discovery 100 years ago. According to recent measurements by physicists at Purdue University, West Lafayette, Ind., the tiny particle may not be a simple negative point charge, as scientists often describe it.
Science and engineering students have learned for years that the electron has a constant electronic strength. but now we've seen that this may not be the case," explains David Koltick, professor of physics. His research shows that the electromagnetic force from the electron, or its electronic strength, may increase while moving toward the particle's central core.
According to his ...
