Béla Bartók wrote the first four volumes of the Mikrokosmos as a series of beginning piano exercises for his son Péter. The great Hungarian composer's complete six-volume collection represents one of the most comprehensive anthologies of contemporary technique ever assembled. This edition, consisting of the first two volumes, presents more than 100 pieces of study material suitable for first- and second-year students. In a 1945 radio interview, Bartók explained, "The Mikrokosmos is a cycle of 153 pieces for piano, written with a didactic purpose. That is, to give piano pieces which can be used from the very beginning and then going on. It is graded according to difficulties. And the word Mikrokosmos may be interpreted as a series of pieces in many different styles, representing a small world. Or it may be interpreted as 'world of the little ones, the children.'" This volume constitutes the definitive edition of Bartók's tutorials, drawing upon all known manuscripts and the printed originals for a corrected version approved by the composer's son and the first student to benefit from these exercises.

This classic guide offers clear, concise instruction in the basics as well as the finer points of pencil drawing. Appropriate for beginning and intermediate students, it features sixty-six well-chosen illustrations that encompass a wide range of subjects — mainly architectural, but also people, animals, and landscapes — and demonstrate a tremendous variety of techniques. An architect, painter, art director, and teacher, Arthur L. Guptill wrote several popular books on drawing. He begins this two-part treatment, aimed at architects, artists, and students, with discussions of drawing objects in outline and in light and shade, the principles of freehand perspective, methods of cast and life drawing, and sketching animals. The second part examines the choice of subjects and drawing in outline and in flat and graded tones. The important subject of composition receives considerable attention, with particular focus on unity and balance. Additional topics include working from photographs and from nature, the representation of buildings — including exteriors, interiors, and street scenes — and portraying details and accessories, from furniture, draperies, doors, and windows to clouds, water, and trees.

Hard-Boiled Egg Index is a true story on the struggles Kudzai Gumunyu and most Zimbabweans went through during the record- and heart-breaking hyper-inflationary period in Zimbabwe. Though saddening, the story is told in a humorous and vivid way detailing how Kudzai had to adjust to the effects of economic meltdown. Zimbabwe's inflation rate reached a mind-boggling 89.7 sextillion percent by 2008 and US$1 was worth 3 nonillion Zimbabwean dollars had the Central Bank not debased the currency three times with twenty-five zeros. The ZWD100 trillion became the highest denomination on the planet. Before the crazily denominated notes, money was being carried in wheelbarrows and grain bags and the purchased item in your hand due to rapid loss of value. Every day became a struggle from shortages of foodstuffs, collapse of services, bank queues, as well a salary that could not keep up with inflation. The writer also gives the life and economic lessons learned, which can be useful to other countries navigating similar economic minefields. It ends with a positive outlook for the country and the hope that the Jewel of Africa (Zimbabwe) will sparkle again given its educated and competent human capital, abundant and rich mineral fields, tourist attractions, rich agricultural lands aided by a favorable climate, as well as, recently, a change of leadership.

While many books explain the how of bitcoin, The Internet of Money delves into the why of bitcoin. Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in 2008, is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide. In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label "digital currency." Andreas goes beyond exploring the technical functioning of the bitcoin network by illuminating bitcoin's philosophical, social, and historical implications. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin--the internet of money--is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.

What is money? How does it work and what effects does it have on our society and economy? Hardly anyone has penetrated the answers to these questions better and explained them more comprehensibly than Alfred Lansburgh, who published them in the form of letters to his son, under the pseudonym "Argentarius" in his publishing house "Die Bank". This edition contains the following collections of letters from the years 1921: On Money (Original "Vom Gelde")

A Progressive's Case for Bitcoin is for everyone who is starting to learn about Bitcoin and wants to understand the reality behind the buzz. Exploring the value proposition of Bitcoin through a progressive lens, Maier's book explores why Bitcoin is good for the environment, how it helps poor and marginalized communities, and why Bitcoin serves as a protest against too-big-to-fail banks: all the people-centric reasons Bitcoin was created in the first place. This inspirational read, which requires no background knowledge, is a great starting point for anyone who is curious about Bitcoin beyond the boundaries of western privilege, clickbait headlines, and social media chatter. “Jason’s book is outstanding, and fills a niche that has been seriously underserved until now —a treatise on Bitcoin for progressives. He thoughtfully walks the reader through the shortcomings of the current financial system and the benefits that Bitcoin can bring to people around the world.” —Lyn Alden, Macro Economist and Investor “In A Progressive’s Case for Bitcoin, Jason offers an uncommon perspective of how Bitcoin can be used as a tool for progressive social change. Through a combination of introspection and real-world case studies, Jason explores how Bitcoin can help to empower marginalized communities including the unbanked, those affected by hyperinflation and more.” —Lamar Wilson, Founder, Black Bitcoin Billionaire “A Progressive's Case for Bitcoin offers a refreshing perspective on Bitcoin particularly suited for a more liberal voter. Maier writes with humility and clarity inviting even the most ardent Bitcoin critics to question their assumptions. It is one of the best books written on Bitcoin.” —Dr. Mark Stephany, Physician and Host of The Progressive Bitcoiner “—If you care about the environment, human rights, or equality, you need to read this book and share it with everyone you know who considers themselves to be a progressive. This is a must read book!” —Dennis Porter, Co-Founder and CEO of the Satoshi Action Fund “Jason Maier has written what may be the most consequential Bitcoin book to date. In our historical moment, everything is politicized, often before it is even understood. So it is with Bitcoin, a technology attacked by many on the political left and embraced by those on the right, but which is actually nothing more than a few hundred lines of code. The social, political, economic, and environmental consequences of Bitcoin have hardly been thought through. Maier shows how Bitcoin—yes, Bitcoin!--actually aligns with the deepest values of progressives and serves their highest goals, most surprisingly, aiding the fight against climate change." “Reading this book, you realize that humanity is on the verge of a devastating mistake. Progressives have always pointed out injustices and critiqued systems of privilege. Yet, in a brilliant PR campaign, those very systems have enlisted progressives to protect themselves from being reformed or disrupted by an upstart technology. Maier’s book is a desperately needed corrective. He explains Bitcoin like a veteran teacher, breezes through arguments in a conversational style, yet his careful reasoning reminds you he is a mathematician. Open-minded progressives, and maybe even close-minded ones, will have to rethink their opinions on the possibilities and promise of neutral, digital money.” —Troy Cross, Environmentalist and Professor of Philosophy, Reed College C. Jason Maier is a teacher of mathematics with a personal conviction about how Bitcoin will reshape the world. More of Jason's writing can be found at www.bitcoinmagazine.com

The new book from one of TIME's 2021 most influential people Author was in Forbes 30 Under 30 Hall of Fame "A crucial contribution to development of a new technology that will impact all of our lives.” –Laura Shin, host of the Unchained podcast and author of The Cryptopians: Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze “Vitalik Buterin is one of the most influential creators of our generation....Like most of his work, it is sure to become a must-read.”–Camila Russo, author of The Infinite Machine, founder of The Defiant The ideas behind Ethereum in the words of its founder, describing a radical vision for more than a digital currency—reinventing organizations, economics, and democracy itself in the age of the internet. When he was only nineteen years old, in late 2013, Vitalik Buterin published a visionary paper outlining the ideas behind what would become Ethereum. He proposed to take what Bitcoin did for currency—replace government and corporate power with power shared among users—and apply it to everyday apps, organizations, and society as a whole. Now, less than a decade later, Ethereum is the second-most-valuable cryptocurrency and serves as the foundation for the weird new world of NFT artworks, virtual real estate in the metaverse, and decentralized autonomous organizations. The essays in Proof of Stake have guided Ethereum’s community of radicals and builders. Here for the first time they are collected from across the internet for new readers. They reveal Buterin as a lively, creative thinker, relentlessly curious and adventuresome in exploring the consequences of his invention. His writing stands in contrast to the hype that so often accompanies crypto in the public imagination. He presents it instead as a fascinating set of social, economic, and political possibilities, opening a window into a conversation that far more of us could be having. Media scholar Nathan Schneiderprovides introductions and notes.
