How Do You Know What Time It Is? (Wells of Knowledge Science Series)

Oppenheim Toy Portfolio Gold Seal Award 2003
What would life be like with no clocks and no calendars? How would you understand when to rise up within the morning? How would you understand when baseball season was about to begin? Lengthy, way back, all individuals might do was watch the solar and moon and attempt to determine issues out. Ultimately, they made easy clocks like sundials. And as time marched on, individuals got here up with extra methods to measure it. At this time, quartz crystal watches and atomic clocks inform us EXACTLY what time it’s, at any second, everywhere in the world.
