This text systematically presents the basics of quantum mechanics, emphasizing the role of Lie groups, Lie algebras, and their unitary representations. The mathematical structure of the subject is brought to the fore, intentionally avoiding significant overlap with material from standard physics courses in quantum mechanics and quantum field theory. The level of presentation is attractive to mathematics students looking to learn about both quantum mechanics and representation theory, while also appealing to physics students who would like to know more about the mathematics underlying the...

When does physics depart the realm of testable hypothesis and come to resemble theology? Peter Woit argues that string theory isn't just going in the wrong direction, it's not even science. Not Even Wrong shows that what many physicists call superstring "theory" is not a theory at all. It makes no predictions, not even wrong ones, and this very lack of falsifiability is what has allowed the subject to survive and flourish. Peter Woit explains why the mathematical conditions for progress in physics are entirely absent from superstring theory today, offering the other side of the story.

'Not Even Wrong' describes the attempts of human beings to understand how the world works at the most fundamental level and what the role of mathematics is in its description. The author's perspective is unusual in that he is sceptical about string theory, which has dominated his field for 20 years.

This all-new hiking guide covers Minnesota's distinct areas of terrain and habitat the northern arboreal forests, the western prairies, the deciduous forests, and the southeastern Mississippi River bluffs. These diverse areas offer a wide variety of hiking experiences, flora and fauna, and spectacular vistas. Ranging from easy walks of several miles to daylong outings, these hikes take advantage of Minnesota's extensive and well-maintained state and national parks. Bonus destinations of historical importance or scenic value also are described. Each chapter includes driving directions to the...
