"'Those who wish to enjoy peace must be ready for war.', [Epaminondas] lectured them [in 370BCE], 700 years before Vegetius's more famous Roman dictum, Qui desiderat pacem, praeparat bellum." --- Victor Davis Hanson 1999 _The Soul of Battle: From Ancient Times to the Present Day, How 3 Great Liberators Vanquished Tyranny_ pg54 |

"Small wonder that after the VOC's [Vereenigde Oost-indische Compagnie's] demise, its logo came to be read as Vergaan onder Corruptie (Perished by corruption)." --- David S. Landes 1999 _The Wealth & Poverty of Nations_ pg 146 (J.S. Furnivall 1939 _Netherlands Indies_ pg 49) |
"«The labouring classes [in the USA] are comparatively few in number», Joseph Whitworth reported on his arrival back home [in England in 1853], «but this is counter-balanced by, and indeed, may be regarded as one of the chief causes of, the eagerness with which they call in the aid of machinery in almost every department of industry. Wherever it can be introduced as a substitute for manual labour, it is universally and willingly resorted to... It is this condition of the labour market, and this eager resort to machinery wherever it can be applied, to which, under the guidance of superior education and intelligence, the prosperity of the USA is mainly due.»" --- Simon Winchester 2018 _The Perfectionists_ pp122-123 |

Except that computer people use 2 as a base raised to multiples of powers of 10, instead of 10 raised to multiples of powers of 3 because powers of 2 are handier for them, but they also want to stay somewhat close to the values of 10 most folks are used to.

"Particles -- in our current theory -- are actually indivisible points in space. That means that in theory they take up zero volume and they are located at exactly one infinitesimal location in 3-dimensional space. There's actually no size to them at all. And since you're made of particles, that means you're not mostly empty space, you are entirely empty space! Think for a moment about how much sense that doesn't make for the concept of mass. Remember that some particles have tiny almost-zero masses and others have enormous fat masses. For example, here's a question that makes little sense [to the authors now]: What is the density of an electron? An electron has non-zero mass and it exists in zero volume, sot he density (mass divided by volume) is actually... undefined? It makes no sense. " --- Jorge Cham, Ph.D. & Daniel Whiteson, Ph.D. 2017 _We Have No Idea_ pg65 |
