100 enigmas que la ciencia (todavia) no ha resuelto

Outlining 100 concepts and phenomena that science has not yet been able to fully explain, this survey examines topics such as the origins of the universe, the possible existence of wormholes, animal migrations, sexual orientation, diseases, cold fusion, and a host of others. In looking at the farthest reaches of time and space; the Earth and the solar system; the human body, health, and life; and technological innovations and challenges, this book demonstrates that for all of the many mysteries science has helped resolve, many others remain—and in some cases, the answers are tantalizingly close.
