Agriculture, like other sectors of the economy, is a profit-driven business. Simple cultivation systems such as monocultures have therefore become firmly established, because they promise higher returns. However, they are more susceptible to diseases and parasites, which can caus … | Continue reading
The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller fractions of time. And in atomic clocks, the world's st … | Continue reading
