"The more I learn the more I know there is to know", adapted from Socrates

"Unthinking respect for authority is the greatest enemy of truth", Albert Einstein

"Extraordinary claims require extraordinary evidence", Carl Sagan.

"Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution". Albert Einstein

"Our aim as scientists is objective truth; more truth, more interesting truth, more intelligible truth. We cannot reasonably aim at certainty. Once we realize that human knowledge is fallible, we realize also that we can never be completely certain that we have not made a mistake" Karl Popper

"Passion (in any argument) is inversely proportional to the amount of real information available", Gregory Benford.

"Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not" Richard Dawkins

"If we are uncritical we shall always find what we want: we shall look for, and find, confirmations, and we shall look away from, and not see, whatever might be dangerous to our pet theories", Karl Popper

"... there is no need to know the truth of the actual matters, but one merely needs to have discovered some device of persuasion which will make one appear to those who do not know to know better than those who know", Socrates in Gorgias

"It has become almost a cliché to remark that nobody boasts of ignorance of literature, but it is socially acceptable to boast ignorance of science and proudly claim incompetence in mathematics", Richard Dawkins

There is an almost universal tendency, perhaps an inborn tendency, to suspect the good faith of a man who holds opinions that differ from our own opinions..." Karl Popper

"I do not attempt to convert my opponents - I aim at converting their audience", David Goodman (DGG), Wiki Administrator

"I'm not an atheist and I don't think I can call myself a pantheist. We are in the position of a little child entering a huge library filled with books in many different languages. The child knows someone must have written those books. It does not know how. The child dimly suspects a mysterious order in the arrangement of the books but doesn't know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God. We see a universe marvelously arranged and obeying certain laws, but only dimly understand these laws", attributed to Albert Einstein.

My Favorite Fathers of Modern Science and Giordano Bruno, the First Martyr of Science

"As long as I have any choice in the matter, I shall live only in a country where civil liberty, tolerance, and equality of all citizens before the law prevail", Albert Einstein

My favorite wonders of engineering[edit]

Wonders of empirical engineering[edit]

The Pantheon, Rome (125 AD). The Pantheon's five-rings coffered dome is still the world's largest unreinforced solid concrete dome. The height to the oculus and the diameter of the interior circle are the same, 43.4 meters.
Gothic cathedrals (12th–14th centuries). The use of the pointed arch, rib vaults and the flying buttress allowed the weight of the roof to be counterbalanced by buttresses outside the building, giving greater height and more space for windows (stained glass, and the rose window) allowing to bring light and color to the interior. From left to right: (1) Choir of Saint-Denis Basilica, considered the first use of all of the elements of gothic architecture (1140-1144); (2) rib vault and rose window, (3) flying buttresses, and (4) the nave of Notre-Dame de Paris (1163–1345); (5) the nave of Westminster Abbey (present church 1245-1376); and (6) rib vault in the nave of Catedral Primada de América, Santo Domingo (1521-1541), the first and the only standing gothic cathedral in the Americas.
Cupola del Brunelleschi, Florence Cathedral (Cattedrale di Santa Maria del Fiore). The dome was built between 1420 and 1436. Florence Cathedral's dome is still the world's largest brick and mortar (masonry) dome. The octagonal dome has 42.05 m in diameter and 45 m wide tambour. The height of the dome is 114.5 m, it stands 52 m above the floor. The dome was built without the use of interior scaffolding supported on the floor (visit pending).

Modern wonders of engineering[edit]

Panama Canal (1914), one of the American Society of Civil Engineers' Seven Wonders of the Modern World, and also listed as one of the Seven Wonders of the Industrial World.
Empire State Building (1931), New York City, a U.S. National Historic Landmark and one of the American Society of Civil Engineers' Seven Wonders of the Modern World. Tops the list of America's Favorite Architecture by the American Institute of Architects. Tallest skyscraper in the world from 1931 to 1970.
Hoover Dam (1936), Nevada-Arizona, a U.S. National Historic Landmark and one of the Seven Wonders of the Industrial World. When nine generators were operational in 1939, the dam's power plant became the world's largest hydroelectricity facility.
Golden Gate Bridge (1937), San Francisco, one of the American Society of Civil Engineers' Seven Wonders of the Modern World. The longest suspension bridge main span in the world from 1937 to 1964.
The modern electric car (1990s to 2010s). From left to right: General Motors EV1 (1996); Chevrolet Volt plug-in hybrid (2010); Tesla Model S all-electric car (2012); BMW i3 BEV/REx (2013); Toyota Mirai hydrogen fuel cell car (2014); and Tesla Model 3 all-electric car (2017). There were over 10 million plug-in electric cars on the world's roads by December 2020.
