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.

Terahertz, symbolized as THz, is a unit of frequency equivalent to one trillion cycles per second, or 1,000,000,000,000 Hz. In the electromagnetic spectrum, terahertz waves occupy the fascinating territory between microwaves and infrared light. This region, often referred to as the “terahertz gap,” has long captivated scientists because of its potential in numerous applications, including advanced imaging techniques, security screening, and even the detection of defects in materials.

Remarkably, terahertz radiation is non-ionizing, meaning it is much safer for biological tissues compared to X-rays. This capability opens doors to potentially revolutionary medical imaging and diagnostics opportunities without the risk of harmful radiation exposure. As researchers continue to explore this “hidden power,” the future holds exciting prospects for terahertz technology across a multitude of fields.
