"About Understanding Science
The mission of Understanding Science is to provide a fun, accessible,
and free resource that accurately communicates what science is and how
it really works. The process of science is exciting, but standard
explanations often miss its dynamic nature. Science affects us all
everyday, but people often feel cut off from science. Science is an
intensely human endeavor, but many portrayals gloss over the passion,
curiosity, and even rivalries and pitfalls that characterize all human
ventures. Understanding Science gives users an inside look at the
general principles, methods, and motivations that underlie all of
science. "
