Parents always hope their children will acquire more scientific knowledge, but the path from pure science to technology is actually extremely long. What truly and directly changes our lives are the successive advancements in technology. Mr. Wu Jun's book A Technology History for Children helps teenagers build a solid foundation in scientific literacy, enabling them to view the world more holistically and integrate knowledge from various disciplines.
— Yu Minhong, Chairman of New Oriental Education & Technology Group

Every child should read a history of technology, as it is essentially the evolutionary history of human thought. How did we, step by step, transform from one species of mammal on this planet into its dominant force? This is a question we inevitably ask when looking back at the long river of history. By the way, at good universities, students in science and engineering often are required to take a course in the history of technology. Because it is general knowledge for deep thinkers.
— Zhang Quanling, Chairman of Shaonian Dedao (Youth Achievement)

I first got to know Mr. Wu Jun by listening to his lectures on The Information Transmission. Mr. Wu is an expert in information science and a masterful storyteller. He consistently uses perfectly apt metaphors, associations, and questions to captivate his audience. This series uses a richly illustrated approach to narrate the development of human technology from primitive society to the future. The text is concise yet not superficial; the content is profound yet not obscure. It covers knowledge in agriculture, industry, science, mathematics, and more. It is truly a rare find in children's literature. I suggest parents use this book as bedtime reading for their children, allowing them to unconsciously learn about the history of human technology and fall in love with science.

I prefer the history of technology because, among all histories, it is more hardcore, more logical, and clearer. After reading A Technology History for Children, it feels like a lush tree of human technology has grown in my mind. The origins of people's work, life, and cultural characteristics today can all be found in this book.

He holds a PhD in Computer Science from Tsinghua University and Johns Hopkins University (a globally top-tier research university). He formerly served as a principal designer of Google's search algorithms for Chinese, Japanese, and Korean and as Vice President of Tencent's search business. He is now an investor based in Silicon Valley.

★ The original work upon which this book is based won the "Wu Dayou Prize for Popular Science Books" and was shortlisted for "China Good Book"!
This book is a quality product validated by both the market and professional circles: it has long been a top-seller in the adolescent popular science category on Dangdang (China's largest online book retailer). It holds an average rating of 8.5/10 on Douban (a major Chinese review platform) with over 400,000 readers recommending it!

★ This book perfectly addresses a global educational focus: cultivating the next generation's core scientific literacy and critical thinking skills!
The book's design aligns highly with concepts emphasized in European and American education systems, such as "Inquiry-based Learning" and "Science Practices." It effectively helps young people build a lifelong framework for scientific thinking. For instance, in Science Lessons, 40 milestone stories completely recreate the entire scientific process, from posing questions and designing experiments to drawing conclusions.

★ A "Scientific Journey" guide that truly sparks curiosity!
From Archimedes in ancient Greece to modern scientists discovering the Higgs boson, this book seamlessly integrates mathematics, physics, chemistry, biology, astronomy, and other disciplines through over 1,000 cross-disciplinary knowledge points and more than 300 vivid and interesting illustrations. It answers those fundamental questions that drive human progress: How do we measure the world? How do we discover unknown elements? How do we "listen" to the echoes of the universe? It helps young readers think like scientists and develop a grand, historical understanding of the technological world we inhabit.

★ "Science is not a collection of facts, but a way of understanding the world." This book is an excellent map to that way of understanding.

This series consists of 4 volumes:
"40 Great Science Adventures"
"A History of Technology"
"The Wonderful World of Math"
"The Language of Technology"

From ancient civilizations to modern science, many achievements in the history of science stemmed from generations of scientists' quests for the unknown:
How did people measure length in ancient times without rulers?
How could one tell if a gold crown was adulterated with silver?
Did alchemists really refine a new element benefiting humanity from 7,000 liters of urine?
Did a moldy melon really save countless lives?
How can we "listen" to changes in cosmic bodies 1.3 billion light-years away?
...

This book meticulously selects 40 of the most representative experiments in human scientific history as its core narrative thread. Using these experiments as anchor points, it constructs 40 fascinating "science lessons." Each lesson revolves around a central scientific question. Dr. Wu Jun not only clearly explains the experiments themselves but also vividly recreates the scientific context of the time, the challenges the scientists faced, and their paths of reasoning.

The content spans millennia, from ancient measurement techniques and the discovery of the law of buoyancy, to modern electromagnetism, genetics, and the verification of relativity, and onward to contemporary particle physics, cosmology, and gravitational wave detection. By traversing this "history of experiments," young readers will personally experience these thrilling "Eureka moments," learning not just scientific knowledge but, more importantly, acquiring the essence of scientific thinking—empiricism, skepticism, logic, and innovation.
