Things We Don't Know (TWDK) is a science communications project, which seeks to help improve the public understanding of science. There are two distinct aspects to science; learning about what science has discovered, and discovering new things. Naturally, a scientist must first learn what we already know before they can start their own research. Here at TWDK we feel that scientists tend to concentrate on explaining the things we already know, and rarely explain the things we don't. TWDK is dedicated to explaining what scientists know we don't know, the questions to which we still seek answers.
