The article discusses the importance of engineering to ensure the creation of simple gadgets that are often overlooked for their simplicity. The article suggests that simple gadgets such as coffee makers, digital watches, and wristwatches are often more complex and more affordable than they are. These include coffee makers that heat water and pass it over the grounds without moving a moving pump, which requires fluid thermodynamics and buoyancy. Digital watches use quartz movements, which can function like tuning forks, and quartz can tell time by converting it to a format digital circuits. E-inkers, particularly affordable and effective measures, have become more affordable due to their compact design. The author also highlights the complexity of measuring time and the importance importance of reading e-ink-readers.
