Containing 97 percent of Earth's water supply, the ocean plays a huge role in regulating global temperatures, supporting plant and animal life, and contributing to the livelihoods of millions of people. But in spite of all this, the ocean remains drastically unexplored, and the details of its impact on human lives aren't fully understood. Scientists from around the world are realizing that to address issues plaguing the ocean, such as dead zones, coral bleaching, and climate change, we need to better understand this incredible, unique feature of our planet. With a range of impressive, cutting-edge technologies at their disposal, oceanographers have set out to measure, sample, and analyze at every turn. Every day, mysteries about the ocean are being solved, and every day, new questions come to light. The more scientists learn, the better they are able to answer these new questions. What lies in the deep? And who is at the forefront of these exciting discoveries? The scientists and research included in this book shed light on the most pressing issues currently facing oceanographers and point us in the right direction to solving these challenges.
In January 2009, a mysterious software developer, Satoshi Nakamoto, exchanged a specially designed code with another developer. The code was a digital currency that Nakamoto had proposed several months before in a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” This was the first Bitcoin transaction. Since then, Bitcoin has become the face of a tech revolution in digital cryptocurrencies based on blockchain technology. Its success has sparked a tech revolution that could fundamentally change global economics. Delve into the world of coders, libertarians, criminals, financial regulators, and crypto-detectives to understand what digital cryptocurrencies have to offer, their limitations and potential pitfalls, security issues, and how they may affect government and financial regulations in the future.
On April 22, 1970, an estimated twenty million people held in a teach-in to show their support for environmental protections. This new celebration, Earth Day, brought together previously fragmented issues under the same banner. It was the largest nationwide event ever, and lawmakers took notice. But one day didn't change everything. Fifty years after the first Earth Day, climate change remains a dire concern. The divide between political parties continues to widen, and environmental policy has become an increasingly partisan issue. The spread of disinformation has also made climate change a debatable idea, rather than scientific fact. A new generation of advocates continue the fight to make environmental policy a top priority for the United States and for nations around the globe
The best part about coding is that anyone with a computer can learn how to do it. From education to healthcare to entertainment, software touches almost every aspect of twenty-first century life. Take a high-level perspective on the types of people who create that software—including many jobs that do not involve writing code at all. Learn about the software development cycle and the huge variety of skills developers draw on, including psychology, mathematics, and art, to create amazing apps and programs. Explore why diversity is needed to prevent bias in design. Learn about the different coding languages and what they are used for, how developers choose a language, and tools that simplify coding. Jennifer Connor-Smith breaks down stereotypes about coding as a career that is open only to technology-obsessed gamers, revealing ways people use software to improve medical care, nurture dementia patients, promote social justice, and more. Hands-on activities show you how easy it is to learn to think like a coder. The next generation of coders will require diverse teams, creativity, and ethical codes of conduct to create the best and most successful software. Will you be one of them?
