The fine-tuned Universe is the proposition that the conditions that allow life in the Universe can occur only when certain universal dimensionless physical constants lie within a very narrow range of values, so that if any of several fundamental constants were only slightly different, the Universe would be unlikely to be conducive to the establishment and development of matter, astronomical structures, elemental diversity, or life as it is understood.

The Antikythera mechanism, a complex clockwork mechanism composed of at least 30 meshing bronze gears.
The mechanism was retrieved from 45 metres (148 ft) of water in the Antikythera shipwreck off Point Glyphadia on the Greek island of Antikythera in 1901, most probably in July of that year. The wreck had been found in April 1900 by a group of Greek sponge divers who retrieved numerous large artefacts
It is not known how the mechanism came to be on the cargo ship, but it has been suggested that it was being taken from Rhodes to Rome, together with other looted treasure, to support a triumphal parade being staged by Julius Caesar
The artefact was retrieved from the sea in 1901, and identified as containing a gear wheel on 17 May 1902 by archaeologist Valerios Stais, among wreckage retrieved from a wreck off the coast of the Greek island Antikythera. The instrument is believed to have been designed and constructed by Greek scientists and has been variously dated to about 87 BC, or between 150 and 100 BC, or to 205 BC, or to within a generation before the shipwreck, which has been dated to approximately 70-60 BC

The Art of War
Author: Sun Tzu
Subject: Military strategy and tactics
Period: 5th century BC
The Art of War is an ancient Chinese military treatise dating from the Spring and Autumn Period (roughly 771 to 476 BC). The work, which is attributed to the ancient Chinese military strategist Sun Tzu ("Master Sun", also spelled Sunzi), is composed of 13 chapters. Each one is devoted to a distinct aspect of warfare and how that applies to military strategy and tactics. For almost 1,500 years it was the lead text in an anthology that would be formalised as the Seven Military Classics by Emperor Shenzong of Song in 1080. The Art of Warremains the most influential strategy text in East Asian warfare. It has a profound influence on both Eastern and Western military thinking, business tactics, legal strategy and beyond
Sun-tzu's Art of War has been credited with influencing Napoleon, the German General Staff, and even the planning for Desert Storm. Many Japanese companies make this book required reading for their key executives. And increasingly, Western businesspeople and others are turning to the Art of War for inspiration and advice on how to succeed in competitive situations of all kinds.
All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.
The Road Not Taken by Robert Frost
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim
Because it was grassy and wanted wear,
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I,
I took the one less traveled by,
And that has made all the difference.

First Disk Drive: IBM RAMAC 350
Computers hold thousands of data records. Imagine if finding the one you wanted required starting with the first, then going through them in order.
High speed, random access memory : RAM —plucking information from storage without plodding through sequentially— is essential to the way we use computers today. IBM’s RAMAC (Random Access Method of Accounting and Control) magnetic disk drive pioneered this ability.
The RAMAC 350 storage unit could hold the equivalent of 62,500 punched cards: 5 million characters (about 3.75 MB).
Due to archaic hole punched cards storage methods, storing information was exceedingly cumbersome and slow.

IBM recognized the need for a storage device that swiftly accessed data in any order. Its RAMAC magnetic disk drive, much faster than any previous technology, unleashed computers’ processing speed by providing inexpensive, fast, large capacity storage (lel?).
