There are so many different types of scientists. What problems are they investigating? #SciCommChallenge takes readers on a journey through the fascinating questions that scientists are investigating around the world. The book does so in two experiments whereby scientists are challenged to communicate their research in less than 200 words (Chapter 1) and also in one tweet (Chapter 2). This first volume is an attempt to begin an important discussion regarding the nature of scientists’ work. It is meant to only be a start and by no means is it exhaustive. The full range of responses is included here to provide opportunities for analysis and discussion by trainees in science, science educators, scientists, and also the public at large.
