Waves are ubiquitous in nature and technology. Whether it’s the rise and fall of ocean tides or the swinging of a clock’s pendulum, the predictable rhythms of waves create a signal that is easy to track and distinguish from other types of signals.
Electronic devices use radio waves to send and receive data, like your laptop and Wi-Fi router or cellphone and cell tower. Similarly, scientists can use a different type of wave to transmit a different type of data: signals from the invisible processes and dynamics underlying how cells make decisions.
