Experiments with rubber balloons and rubber sheets have led to surprising observations, some of them hitherto unknown or not previously described in the literature. In balloons, these phenomena are due to the non-monotonic pressure-radius characteristic which makes balloons a subject of interest to physicists engaged in stability studies. Here is a situation in which symmetry breaking and hysteresis may be studied analytically, because the stress-stretch relations of rubber - and its non-convex free energy - can be determined explicitly from the kinetic theory of rubber and from non-linear elasticity. Since rubber elasticity and the elasticity of gases are both entropy-induced, a rubber balloon represents a compromise between the entropic tendency of a gas to expand and the entropic tendency of rubber to contract. Thus rubber and rubber balloons furnish instructive paradigms of thermodynamics. This monograph treats the subject at a level appropriate for post-graduate studies.

Enthusiasts look forward to a time when tiny machines reassemble matter and process information but is their vision realistic? 'Soft Machines' explains why the nanoworld is so different to the macro-world that we are all familar with and shows how it has more in common with biology than conventional engineering.
Surprising history of ordinary things Learn the fascinating history and trivia you never knew about things we use daily from the host of The Story Behind podcast. Everyday objects and major events in history: Every single thing that surrounds us has a story behind it. Many of us learn the history of humans and the major inventions that shaped our world. But what you may not have learned is the history of objects we surround ourselves with every day. You might not even know how the major events in history (World Wars, ancient civilizations, revolutions, etc.) influenced the inventions of things we use today. The history and science behind the ordinary: From the creator of The Story Behind podcast comes this revelatory new book. The Story Behind will give insight into everyday objects we don’t think much about when we use them. Topics covered in the podcast will be examined in more detail along with many new fascinating topics. Learn how lollipops got started in Ancient Egypt, how podcasts were invented, and why Comic Sans was created. Learn the torture device origins of certain exercise equipment and the espionage beginnings of certain musical instruments. Ordinary things from science to art, food to sports, customs to fashion, and more are explored. Readers will: • Understand the wonders behind everyday objects • Learn truly obscure history and fun facts that will change the way they see the world • Learn how major historic events still affect us today through seemingly mundane things • Become formidable trivia masters
