POWER

How close are we to the brink of something? Or how close to a shore? Electrical essences in the basement! Do you realize how much things have changed in the past two centuries?

A Canticle For Leibowitz by Walter M. Miller, Jr. (1959)

Ground Pattern

There are depths in man that go the length of lowest Hell, as there are heights that reach highest Heaven – for are not both Heaven and Hell made out of him, made by him, everlasting Miracle and Mystery as he is?

Electromagnetic

Heard of terahertz waves?

The terahertz (1 trillion cycles per second) gap refers to a portion of the electromagnetic spectrum where efficient generation, detection, and manipulation of radiation have been very challenging. It’s found from 0.1 THz to 10 THz, between the technologies of infrared/optics and microwave/electronics.

Passes through clothing, paper, plastics, ceramics. Strongly absorbed by water and many molecules. Sensitive to moisture; good for spectroscopy. Reflects off metals. Safer than X-rays for human scanning.

Wireless Communication (6G and beyond) — THz bands offer enormous bandwidth for ultra-high-speed data (terabits per second), though with short range and high atmospheric absorption.
