Synopsis

Databases are structured collections of data that enable efficient retrieval, insertion, updating, and deletion of information. They serve as the foundation for various applications, from simple contact lists to complex enterprise systems. Key concepts include tables, which organize data into rows and columns; relationships, which define connections between tables; and SQL (Structured Query Language), used to interact with databases by querying and manipulating data.

    Evolution Is Wrong - A Radical...

    A Fascinating Exploration on Why the Darwinists’ Theory No Longer Explains EverythingThere was once a set of ideas called the theory of evolution, conceived by clever people and confirmed by countless scientists. Then people discovered the electron microscope. This made it possible to make the molecules within the cell visible, and suddenly questions about evolution arose that were not possible before. Which force actually bundles the atoms in the right order? What moves the molecular chains into the correct position? How did the first living unit within the cell actually come about? How does inheritance work, how does information pass on to the next generation? Did humans descend only and exclusively from primates—as Charles Darwin and countless other great minds assumed—or did additional “engines” intervene in evolution? Today it is clear: countless questions can no longer be answered with the previous theory of evolution. There is a form of life called “Blob” (Physarum polycephalum). The “thing” has neither eyes nor ears, neither a mouth nor a nose or even a brain. Nevertheless, it takes in food, overcomes obstacles by the shortest route and exchanges information with other “blobs.” The “blob” contradicts any evolutionary thought that one develops from the other. Or the “gastric-brooding frogs” (Rheobatrachus) found in Australia. They hatch their young in the stomach. Impossible in a slow, evolutionary process. Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called “Intelligent Design.” Intelligent planning is suspected behind this. Anyone or anything—a spirit of the universe? Aliens?—could be behind this planning. Erich von Däniken uses countless examples to demonstrate the impossibility of the previous evolutionary idea. He quotes scientists who argue against the previous teaching, but also those who defend it. Unfortunately, established science still refuses to look at discrepancies and holes in the theory of evolution, even though it is quite obvious that there is more going on with regard to the development of all species, as well as human culture, than could be explained by the theory of evolution alone.

    An introduction to the basics of blockchain technology. 
    Are you confused by the blockchain? 
    Do you know what it is and how it works? 
    Do you want to know how it can change the world? 
    Then, you’ve chosen the right book. 
    Blockchain technology is not new. In fact, it was introduced in 2009 with the Bitcoin cryptocurrency, but since then, things have moved on at a significant pace. These days, many industries are developing their own blockchain-based solutions, looking to replace their existing database and record-keeping systems with one that works faster and is far more secure. 
    In this book, you will learn:What blockchain isHow blockchain works – a brief overview and a more technical lookThe history of blockchain technology and BitcoinThe advantages and disadvantages of blockchain technologyHow blockchain works with the financial industryHow it works with other industriesHow decentralized apps and smart contracts workWhat the proof-of-work concept is and how it worksThe current and future use cases for the blockchainWhat Ripple and the R3 consortium areAnd much more 
    The blockchain has already changed the world in so many ways, and most of us aren’t even aware that the systems we’ve used every day have changed. Not every blockchain is decentralized; some still have a centralized intermediary. Not every blockchain is open-source. Banks, governments, and financial institutions are all maintaining control but in a more open, secure way that is far less open to fraud than previous financial transaction systems.

    This audiobook is narrated by an AI Voice.  Firing the Cloud: How Humanity Survived and Accelerated is a sweeping, provocative journey through 15,000 years of human history tracing how we evolved from small, fire-lit bands of hunter-gatherers to a globally networked civilisation living inside a digital cloud. 
     
    The book explores the great transitions that shaped us: the Agricultural Revolution’s trade of autonomy for stability, the Industrial Age’s relentless acceleration and the Technological Era’s shift from reality to virtuality. Each chapter weaves anthropology, history, and systems thinking to reveal what we gained and what we lost at every turn. 
     
    Thoughtful, urgent and ultimately hopeful, this audiobook challenges listeners to become memory-keepers of the human story and to shape a future that is not only faster, but wiser.

    For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years. 
     
     
     
    Now we face a human-made climate crisis with drastic consequences. The complete story behind greenhouse gases, however, involves microbes and their role in natural ecosystems. Microscopic organisms are also part of the solution, producing biofuels and other forms of green energy which keep fossil fuels in the ground. Other microbes can be harnessed to reduce the release of methane and nitrous oxide from agriculture, and geoengineering solutions that depend on microbes could pull carbon dioxide out of the atmosphere. 
     
     
     
    David L. Kirchman introduces a unique and timely contribution to the climate change conversation and the part microbes play in our past, present, and future. He takes listeners into the unseen world behind the most important environmental problem facing society today and encourages us to embrace microbial solutions.

    Are you a man looking to get into nursing and do not know how to? 
    Do you wish to understand just what it takes to become a nurse in a female-dominated field? 
    If so, then you have come to the right place. 
    This book will usher you into the world of being a male nurse and thriving at it! 
    For a better part of the last decade, nursing has been considered a female domain, with men being looked at as anomalies in the field. The view that men cannot make good nurses has thus led to widespread stereotypes of men who get into the field. Men in nursing are generally often viewed with suspicion, with people even questioning their sexual orientation.  
    However, as you will learn in this book, nursing had originally been a field meant for men. During the old periods up until the 19thcentury, large-scale caregiving was a role that was meant for men. Thus, this already defeats the stereotype that men lack the necessary temperament to get into nursing. 
    Furthermore, men who get into nursing consider it the most fulfilling profession that they could choose and simply want to care for people. 
    So, perhaps you may be wondering… 
    Why is it hard for men to get into nursing? 
    What are some of the challenges male nurses face in the profession? 
    How do female nurses react to and treat their male colleagues? 
    What are male nurses doing to change the negative perception of men in the field? 
    What does the future hold for male nurses? 
    If these and many questions are bothering you, then this is the book that answers them and more, as it covers the ins and outs of becoming a male nurse and how to make the best of it.
