How amazingly complex and interesting everything around us is: the Internet and cellular communication, electricity and sewage systems, waste recycling and solar energy!
This book is your guide to the world of useful inventions, modern technologies, and "smart" mechanisms.
Examine familiar objects and devices in the smallest detail on huge fold-out pages and understand all the intricacies of complex processes - from baking pizza to purifying water and launching a satellite.
Find out why the refrigerator is cold, how the toaster knows the bread is toasted, which machines have cams and drums, and why a doorbell needs a hammer and a flush tank needs a float.
Learn how you use photocells, satellite signals, alternating current, and magnetic fields every day.
Open the book - the journey begins!
