The millihertz (mHz) is a unit of frequency equal to one-thousandth of a hertz. While it sounds minuscule, frequencies at this scale have critical applications in science and technology. For example, the Earth’s rotation slows down over time, a phenomenon observable at the millihertz level. Measuring such tiny variations requires precise timing methods, akin to those used in atomic clocks that define international time standards.

In the realm of biology, certain very slow rhythms in the human body, such as some brainwave patterns, occur at millihertz frequencies. Understanding these subtle oscillations can provide insights into sleep cycles and neurological conditions. Millihertz frequencies are also employed in geophysics for monitoring seismic activities and gravitational wave detection, highlighting their significance in uncovering the mysteries of the universe.

Did you know?

Hertz (Hz), the unit of frequency, measures the number of cycles per second. It’s named after Heinrich Hertz, the physicist who first proved the existence of electromagnetic waves. In 1888, his groundbreaking experiments paved the way for the development of radio, television, and other communication technologies. Fascinatingly, the concept of frequency extends well beyond sound — it’s also crucial in physics, describing phenomena such as light waves and even the rotation of electron orbitals.

In our everyday lives, Hertz is everywhere. When you listen to music, the pitch you hear is influenced by the frequency in Hertz, with middle C on a piano vibrating at about 261.6 Hz. Even your household electrical system operates at frequencies of 50 or 60 Hz, depending on your region. This widespread influence underscores how integral Hertz is to both technology and daily experiences.
