Lean back and settle in for cutting-edge scientific snippets from the trend-setting Dr Karl Kruszelnicki. In Short Back & Science, Dr Karl combs through some of the greatest scientific conundrums of our age, such as what is killing half the bacteria on Earth every two days and why don't mole rats get cancer? Why would anyone pay $40 million for a cup of tea, and how did a toilet seat help to end the First World War? Are bananas really slippery, radioactive and loaded with potassium? What do clouds weigh? And why are there scientists running around naked in the Antarctic? Brushing aside any hype about coconuts and antioxidants, there is no one better to trim down to the facts than Australia's most trusted scientist, Dr Karl. This is a specially formatted fixed layout ebook that retains the look and feel of the print book.

Australia's favourite science guru explains the facts about climate change -- and how we can fix it How do Greenhouse Gas molecules shimmy and shake to trap 400,000 Hiroshima atom bombs' worth of the Sun's heat each day? Who did the early research into Climate Change and then spent billions trying to cover it up? What's the Hockey Stick Graph and why is it so important? How did Climate Change tip the Earth off its axis? Why was Sydney the hottest place on Earth on 4 January 2020? How can we move to zero and even negative emissions? How can kelp help? When it comes to long-haul transport, why is hydrogen the way to go? And much more! Now, in this never dull, easy-to-understand guide Dr Karl explains the science of climate change and how we can fix it. (We can!)

Why do stars seem to twinkle? Where do all the teaspoons go? Why is the Giant Panda so paradoxical? Why does dark matter matter? The world around (and inside) us is completely astonishing. Dr Karl Kruszelnicki, the most esteemed science communicator in Australia, has chosen 101 fascinating facts from his bestselling books to delight and intrigue you. Taking a microscope to everyday science he gives us insights into the surprising origins of the "selfie", the rise and rise of 3D printing, how a nit is hatched by massive amounts of farting, why humans are basically fat doughnuts, and how you can stop milk from spoiling by dropping a Russian brown frog into it. These are things you need to know. These are things you don't even know you need to know. A riveting ride through the extraordinary world of science.

The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

How do waves break, and what makes good surf? What are dangerous rip currents, and how do you spot one? What should you do if you get caught in one? Australia’s best-known surf scientist, Rob “Dr. Rip” Brander, takes readers on a fascinating and entertaining journey to uncover how beaches form and behave, the science of waves and currents, and how beaches respond to storms and climate change. He explains where the sand we lay our towels on came from, how the tides that wash up new treasures each day work, why no two beaches are exactly the same, and why some of them are disappearing. He also explores some of the hazards to watch out for, from rip currents to tsunamis to the (unlikely) event you find yourself swimming with a shark. Whether you’re a surfer looking for the perfect wave or you just enjoy hitting the beach with friends and family, this book is a must-read for all ocean lovers.
