“It is my purpose to build a bridge which shall not only be the greatest bridge ever built, but one that will be an object of beauty, simple in its lines, and harmonious with its surroundings.” – Joseph Strauss.
“A great bridge in a great city, although primarily utilitarian in its purpose, should nevertheless be a work of art to which Science lends its aid.” – Othmar Ammann.
“The sun never sets on a Man-Chung Tang bridge.” – Man-Chung Tang.
“Structural mechanics is the basis of engineering. Yes, engineers must have more imagination, more creativity… but they must never lose mathematics and structural mechanics. If they lose that, they lose everything. They’ll become under-architects.” – Michel Virlogeux.

AI: Roman Slaves, Russian Serfs, and American Slaves Compared: Human Tragedy 💔

“Sell your old oxen, your blemished cattle, your blemished sheep, your wool, your hides, your old wagon, your old tools, your old slave, and your sick slave, and if anything else is superfluous, sell it. The head of a family should be a seller, not a buyer.” – Cato the Elder, De Agri Cultura (Illustrating the view of slaves as disposable assets).

“I looked around me – my soul was tormented by the российского пространства (vastness/suffering of Russia).” – Alexander Radishchev, Journey from St. Petersburg to Moscow (1790). Radishchev’s book was a scathing early critique of serfdom, detailing the abuses and hardships faced by serfs, for which he was exiled.

AI: Galileo Galilei, Johannes Kepler, and Christiaan Huygens Compared: The Telescope Revolutionized Astronomy in the 17th Century 🔭

“Philosophy [i.e., science] is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it; without these, one wanders about in a dark labyrinth.” – Galileo Galilei
“O telescope, instrument of much knowledge, more precious than any sceptre!” – Johannes Kepler
“The more I observe, the more I see that nature is full of order and laws.” – Christiaan Huygens

AI: Herodotus, Thucydides, and Plutarch Compared: Ancient Greek Historians (Part III, Plutarch: “The Lives of the Noble Grecians and Romans” ⚖️)

“For it is not Histories that I am writing, but Lives; and in the most illustrious deeds there is not always a manifestation of virtue or vice, nay, a slight thing like a phrase or a jest often makes a greater revelation of character than battles where thousands fall…” – Plutarch, Life of Alexander
“An imbalance between rich and poor is the oldest and most fatal ailment of all republics.” – Plutarch
“Painting is silent poetry, and poetry is painting that speaks.” – Plutarch

AI: Herodotus, Thucydides, and Plutarch Compared: Ancient Greek Historians (Part II, Thucydides: “The History of the Peloponnesian War” 🗣️)

“Thucydides, an Athenian, wrote the history of the war between the Peloponnesians and the Athenians, beginning at the moment that it broke out, and believing that it would be a great war, and more worthy of relation than any that had preceded it.”- Thucydides

“Our constitution is called a democracy, because it is in the hands not of the few but of the many. Yet our administration, while securing equal justice to all alike in their private disputes, does not ignore the claim of excellence. When a citizen distinguishes himself, then he will be called to serve the state, in preference to his fellows, not as a matter of privilege, but as a reward of merit; and poverty, so far from being a cause of hindrance, is rather a stimulus to exertion.” – Pericles’ Funeral Oration

“Consider, Athenians, my past service and the piety with which I have served the divine. Though fortune now turns against me, my life has been one of devotion to the state. Pity this army, now facing utter ruin, and remember that those who act unjustly, even if they prosper for a time, will ultimately face the wrath of the gods.” – Nicias (The Siege of Syracuse)

AI: Herodotus, Thucydides, and Plutarch Compared: Ancient Greek Historians (Part I, “The History of Herodotus” or “Persian Wars” 🔎)

“Herodotus of Halicarnassus here displays his inquiry, so that human achievements may not be forgotten in time, and great and marvelous deeds – some displayed by Greeks, some by barbarians – may not be without their glory; and especially to show why the two peoples fought with each other.” – Herodotus
“[The Oracle at Delphi told Croesus:] that if he should send an army against the Persians he would destroy a great empire.”
“[The Oracle at Delphi advising the Athenians:] ‘Yet Zeus grants… a wooden wall, which alone shall be uncaptured, a blessing to you and your children.'”

AI: ♨️ Gilbert N. Lewis, ☮️ Linus Pauling, 💊 Dorothy Crowfoot Hodgkin, ⚗️ Robert Burns Woodward, and 🎥 Ahmed Zewail Compared: Modern Chemists

“Thermodynamics predicts the possibilities, not the probabilities.” – Gilbert N. Lewis. This view reflects his understanding that thermodynamics determines whether a reaction can occur spontaneously (possibility/feasibility) but not how fast it will occur (probability/rate).

“Facts are the air of scientists. Without them, you can never fly.” – Linus Pauling

“I don’t feel that there are any particular difficulties about being a woman in science… except for the interruptions.” – Dorothy Crowfoot Hodgkin

“It has seemed interesting to me that the human mind, looking only at the structure of the molecule, could create such a complex sequence of reactions.” – Robert Burns Woodward.

“Just as geographical exploration enriched humankind’s knowledge of the world, chemical exploration using femtosecond lasers is enriching our knowledge of the world of molecules.” – Ahmed Zewail.

“Atoms cannot be seen, but we infer their existence and properties from the ways in which substances behave.” – John Dalton

“Every chemical combination is wholly and solely dependent on two opposing forces, positive and negative electricity, and every chemical compound must be composed of two parts combined by the agency of their electrochemical reaction since there is no third force.” – Jöns Jacob Berzelius

“The periodic law discovered by me, being not merely a summary of facts, but a reliable and fruitful method of investigation, may serve as a means of further progress in the discovery of new elements.” – Dmitri Mendeleev

“Marie Curie is, of all celebrated beings, the only one whom fame has not corrupted.” – Albert Einstein

Isabella I of Castile was “very powerful, very prudent, wise, very honest, chaste, devout, discreet, truthful, clear, without deceit. Who could count the excellences of this very Catholic and happy Queen, always very worthy of praises.” – Andrés Bernáldez

“My loving people, we have been persuaded by some that are careful of our safety, to take heed how we commit ourself to armed multitudes for fear of treachery; but I assure you, I do not desire to live to distrust my faithful and loving people … I know I have the body but of a weak and feeble woman, but I have the heart and stomach of a king, and of a King of England too, and think foul scorn that Parma or Spain, or any Prince of Europe should dare to invade the borders of my realm.” – Elizabeth I to the Troops at Tilbury

“I found myself without money, without credit, without army, without experience and knowledge of my own and finally, also without any counsel because each one of them at first wanted to wait and see how things would develop.” – Maria Theresa

“I praise loudly, I blame softly.” – Catherine The Great

“The British Empire is a great moral force for good in the world.” – Queen Victoria
