To See a World in a Grain of Sand: Fifteen Ways to Look at a Computer 

By Linda Liukas

Renowned Finnish author and programming instructor Linda Liukas unravels the human stories behind computers - from the first line of code to the birth of the bit - revealing how these breakthroughs shaped our world and where technology is taking us next.
 
What do a British society lady in 1843 and a juggling mathematician some hundred years later have in common? The former wrote the first line of code, and the latter invented the bit - both crucial components of the machine that would change the world.

Taking the reader on a journey across a fascinating map of computer science, Linda Liukas’ book takes a panoramic route to the present day, stopping at fas­cinating human events and revolutiona­ry ideas. At the same time, it takes an insightful look at the impact of techno­logy on our lives and reflects on where the computer is heading next - and us with it.

About the author

Linda Liukas is Finland’s most renowned coding ambassador and author-illustrator. Linda travels the world as a keynote speaker and her speaking topics range from education to AI. She shares the message of embracing coding and computing at technology conferences, teacher training sessions and even at the United Nations. Her 2015 TED talk has gathered over 2 million views. In 2014 Liukas was awarded Finland’s State Prize for her services to making digital technology education accessible for children. In 2017 Linda won China’s biggest design award, the Design Intelligence Award, and in 2018 she was named by Forbes list as one of the most influential women in tech. Linda is the creator of Hello Ruby, a children’s picture book series about the whimsical world of computers which has been a worldwide success story since its release in 2015. The Hello Ruby series has been translated into 37 languages. Hello Ruby made its debut on Kickstarter and quickly reached its $10,000 funding goal after just 3.5 hours, gathering 380 000 dollars in total funding. Linda is co-founder of Rails Girls, a global initiative teaching coding to girls in over 260 cities. Linda has studied business, design and engineering at Aalto University and product engineering at Stanford University.She loves Muji, Zelda Fitzgerald, software, and sparkly things.“Writing software is about expression, creativity, and practical application. Our kids should learn to bend, join, break and combine code in a way it wasn’t designed to. Just as they would with crayons and paper or wood and tools. I believe there’s plenty to learn in programming logic and culture before showing children a single screen.” – Linda Liukas

Reviews

“Now that computers, algorithms, and information networks are a big part of everyone's daily life, it would be wise to have at least some basic understanding of what it's all about. This book is an excellent work that increases everyone's understanding. Liukas writes in an engaging and enjoyable style. In places, the issues are explained in great detail, without giving the reader the feeling of being underestimated. The book also does not resort to pandering to readers by oversimplifying, but instead focuses on the core of the subject matter throughout.”

Mikko With, author

“In this fascinating and educational book, Linda recounts her journey with computers and data processing in the first person, while also reviewing the development of computers and the people and ideas behind them. In addition to purely technological developments, the book considers, for example, how beauty and aesthetics are expressed in technology and programming, and the importance of curiosity in development and learning. Towards the end of the book, we follow the exciting parallel development of Linda's baby and artificial intelligence.”

Katrin kirjahylly

"To an average person like me, computer science (or computer engineering in general) seems dauntingly technical and inaccessible.(...)Linda Liukas' To See a World in a Grain of Sand is for people like me. The book is about what computer science really is, but from an unusual perspective. It examines it through human stories and experiences, which may sound unusual, but I will come back to the genius of the approach later.(...) However, Liukas manages to capture a broader perspective in his book, which makes the reading experience even philosophical in places. A great work, especially for people who are not technology wunderkinds.”

"Over the years and decades, I have read many books on IT, but nothing like this book by Liukas. The book combines humanistic thinking with technology, as well as its meaning and implications, in a fluent yet thought-provoking way. No background in technology or programming is needed to read the book, perhaps more a curious mind, plenty of curiosity and an open mind. (...) If you’re deeply familiar with computers, read this book — you’ll see things in new ways. If you’re not, and don’t care to be, read this book anyway.”

Kaisa Vähähyyppä, Dimesio Magazine

“Liukas moves from algorithms to mycelium, walks through the who’s who of computing, visits museums and factories, flâneurs in Paris, and traces the growth of an AI alongside a human child. She’s a darn good writer. Her sentences flow and sing. She makes technology feel. (...) Liukas knows how to imagine and be curious. This makes the style of the book approachable and interesting. In this book, we are on a journey of discovery together, although Liukas undeniably leads and coaxes us forward skilfully along the path. She interprets a star map for the reader and tells a narrative about it."
