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.

Inside the Human Cell

I check my heart now, and I find that there is still a feeling there, of something hot & struggling.

I roll my eyes back under my closed lids, and there is the sense of opening in the middle of my forehead.

The chest thing is like fighting for words and the forehead thing is pure & empty, like after all the words have been said.

There now. Belief.

I have the biology of it. All I need is the stuff to put in there. All I need are the words.

Be the architect of your life. Know how to arrange it with intelligence. Plant its foundation firmly and develop it with foresight. Life’s a difficult, fatiguing expedition. Intellectual stimulation mixes well with the dust & stones of the long road to eternity.

Theatrics

What society thinks of as reality today is the hypnosis of social conditioning, an induced fiction in which we are all collectively participating.

It is the melodrama of existence, filled with obsessions & pursuits, wherein our only fate is to be born and grow old.
