PDF-(BOOS)-Supernova (The MIT Press Essential Knowledge series)

A concise illustrated introduction to the history and physics of supernovae the brilliant explosions of stars with striking color illustrations Supernovae are the explosions of stars They are some of the most energetic phenomena in the Universe rivaling the combined light of billions of stars Supernovae have been studied for centuries and they have also made appearances in popular culture a glimpse of a supernova in a painting provides Sherlock Holmes with a crucial clue for example In this volume in the MIT Press Essential Knowledge series astrophysicist Or Graur offers a concise and accessible introduction to these aweinspiring astronomical phenomenaGraur explains that a deep observational understanding of supernovaewhy and how they shine and how their brightness changes over timeallows us to use them as tools for experiments in astrophysics and physics A certain type of supernova for example brightens and fades in such a predictable manner that we can measure the distances to their host galaxies We owe our existence to supernovaethey give us iron for our blood and calcium for our bones But supernovae may also have caused a mass extinction event on Earth 26 million years agoGraur shows how observations of supernovae played a role in the transformation of astronomy from astrology to astrophysics surveys the tools used to study supernovae today and describes the lives and deaths of stars and the supernova remnants neutron stars and black holes they leave behind Illustrations in both color and black and white many from Graurs own Hubble Space Telescope data make this account of supernovae particularly vivid.

Peppermint comes from the blending of watermint and spearmint, and has a very strong, minty flavour and scent that is exquisitely refreshing. It tastes delicious, which is why it is commonly paired with chocolate and other desserts or candies, but you’ll also find peppermint in all sorts of cosmetics, including soaps, shampoos, face scrubs, toothpastes and mouthwash. Essential oils have been making waves in health and wellness communities because of the incredible benefits they have for your body and mind, so it should come as no surprise that essential oils also work wonders on your hair! If you were to ask ten people what they love about essential oils and why they actively choose to incorporate them into their daily routine, each person would have a different answer. That is because every essential oil offers a range of health and wellness benefits for your body and mind, and they are all as unique as the person using them. If you are looking for a more natural way to freshen up a room, soothe an ache or ease anxiety, it’s time to try essential oils. Essential oils are natural extracts from the stems, leaves, bark and flowers of special plants, obtained through distillation or cold pressing. The oils themselves are very strong, so they are then mixed with a carrier oil, to be used safely. They are called “essential” oils because they capture the plants flavour and scent, also known as its “essence”. Natural essential oils are often used in aromatherapy, a form of alternative medicine to support health and well-being, but there are many ways to use them. Wondering how to safely use essential oils for adults? No worries, here’s everything you need to know about essential oils! Fifty years ago, neuroscientists thought that a mature brain was fixed like a fly in amber, unable to change. Today, we know that our brains and nervous systems change throughout our lifetimes. This concept of neuroplasticity has captured the imagination of a public eager for self-improvement--and has inspired countless Internet entrepreneurs who peddle dubious brain training games and apps. In this book, Moheb Costandi offers a concise and engaging overview of neuroplasticity for the general reader, describing how our brains change continuously in response to our actions and experiences.Costandi discusses key experimental findings, and describes how our thinking about the brain has evolved over time. He explains how the brain changes during development, and the synaptic pruning that takes place before brain maturity. He shows that adult brains can grow new cells (citing, among many other studies, research showing that sexually mature male canaries learn a new song every year). He describes the kind of brain training that can bring about improvement in brain function. It\'s not gadgets and games that promise to rewire your brain but such sustained cognitive tasks as learning a musical instrument or a new language. (Costandi also notes that London cabbies increase their gray matter after rigorous training in their city\'s complicated streets.) He tells how brains compensate after stroke or injury describes addiction and pain as maladaptive forms of neuroplasticity and considers brain changes that accompany childhood, adolescence, parenthood, and aging. Each of our brains is custom-built. Neuroplasticity is at the heart of what makes us human.
