The great Paris tower was underway. From each corner of a broad base the size of a football field, four spidery iron structures rose, curving inward in one majestic sweep toward the middle. The construction – a web of connecting girders – called for 300 workers to assemble some 15,000 pieces of iron and snap 2.5 million rivets into place. This would be the world’s tallest man-made structure, reaching a height of 300 meters (934 feet). A glorious demonstration of engineering, it was conceived by Gustave Eiffel, the most illustrious engineer of nineteenth-century France. The tower was to be the focal point of the International Exhibition of Paris in 1889, commemorating the 100th birthday of the French Revolution. After that, since it had no practical use, it was to be torn down. It took two years, two months, and three days to build the Eiffel Tower. Eiffel used wrought iron, which was a relatively new building material at the time, used primarily for bridges and aqueducts. As the tower rose, becoming the city’s most prominent feature, not everyone approved. “Useless and monstrous,” one newspaper called it. Another described it as an “odious column of bolted metal.” Called the Magician of Iron, Eiffel’s mathematical prowess and attention to detail was legendary. To put the tower project on paper took 30 draftsmen working full time for 18 months. Every rivet of the 2.5 million needed for the structure had its designated place, down to a fraction of a millimeter. The Tower became the hit of the International Exhibition, with nearly two million people visiting it. Still, not everyone loved this prodigious web of steel girders. A famous writer was once asked why he ate lunch there every day, since he was known to hate the sight of it. He replied, “Because it’s the only place in Paris where I can’t see the damn thing.” So why wasn’t the Eiffel Tower torn down? It almost was. What saved it was the radio broadcasting center and the weather station that Eiffel installed at the top. Now France’s most famous landmark, it is not the only national symbol that Eiffel was involved with. He also built the iron skeleton of a lady we’re all familiar with: The Statue of Liberty. As for the Eiffel Tower, “I ought to be jealous of that tower,” he once said. “She is more famous than I am.”  The Eiffel Tower under construction highlights the intricacy of the design as well as the massive size of the project in relation to the city of Paris.

Eiffel's most famous works are still major tourist attractions in the 21st century. The Eiffel Tower is the most-visited paid monument in the world. An average of 25,000 people ascend the tower every day. Approximately four million people visit New York's Statue of Liberty National Monument and Ellis Island each year.

In spring 1665 a college student named Isaac Newton studied natural philosophy, what we call “science.” Back then, a good student could learn everything to know about the natural world. But plague, the Black Death, came to England. Cambridge University closed. Isaac went home to Woolsthorpe. For two years Isaac thought about his studies during four years at university. He’d always been thoughtful—not the best at games, making friends, or minding sheep. But everybody knew Isaac Newton liked to think. Folks told time by the sundial he’d drawn on a wall. Home at Woolsthorpe, Isaac’s learning about science and math bubbled up in his head like yeast rising in a loaf of bread. So... Newton unplugged. His mind roamed like that of an artist or composer. He was driven by the need to create—not paintings or symphonies, but questions. “Why do things always fall down?” “Why does the earth move around the sun? “Why doesn’t the moon fall onto the earth?” “Does everything ‘up there” work like things work ‘down here?’” Isaac Newton answered his questions with three science rules, Newton’s Laws of Motion. At Woolsthorpe, Newton grappled with the concept of moving objects. He worked out the math to find the area under curves. He called this math fluxions. Today we call this calculus, useful for launching rockets or tracking TV signals. Once back at Cambridge, Newton said nothing until he read someone else’s paper on fluxions. Newton published a better paper. Soon he was Cambridge’s top math professor. Isaac Newton wondered another twenty years. He played with prisms in a dark room and theorized that white light comprises the visible spectrum of red, orange, yellow, green, blue, indigo, and violet. He practiced alchemy and chemistry, looking for the legendary philosopher’s stone to turn base metals to gold. In 1687, Newton published our most important science book, the Principia. In the Principia, Newton showed how laws of gravity and motion work the same at great distances—far off in space, or in your classroom. We accept these ideas, but in 1687 many still had medieval beliefs that sun, moon, planets, and stars all traveled in their own crystal spheres. Yes, Newton wondered about A LOT:

 The Renaissance began in Europe in the 15th century and marked the change from the medieval period to the modern world. Towering figures such as Michelangelo, Galileo, and especially Leonardo da Vinci were known as Renaissance men because of their talents and lasting achievements in several important areas of knowledge. They were also accomplished musicians, public speakers, athletes, poets, and so forth. And they were expected to do all this stuff without breaking a sweat. You could give the same title to an ancient Egyptian named Imhotep, who lived about 2600 BCE. He was the vizier, the most important government official, during the reign of Pharaoh Djoser. He served as the high priest of the god Ra and was an expert astronomer. Imhotep designed and oversaw the building of the first major pyramid in Egypt. Located at Saqqara, at the time it was the world’s tallest structure. He innovated the use of stones rather than mud bricks to build it, and it was that added strength that enabled the pyramid to rise so high. He is also credited with the invention of several devices that facilitated the construction. Many people believe that Imhotep, rather than the Greek Hippocrates who lived more than 2,000 years later, is the real “Father of Medicine.” In an era when most physicians relied on magic spells and appeals to the gods, Imhotep prescribed dozens of effective down-to-earth treatments for illnesses and injuries. He is credited with ending a seven-year famine in Egypt. He advised the pharaoh to make sacrifices to Khnum, the god of the annual flooding of the Nile River, and thereby provide desperately needed water to farmers. On a more practical level, he invented an improved irrigation system to carry water to the crops even if the river level was abnormally low. In addition to these accomplishments, an inscription at the base of one of his statues notes that he was “Chief Carpenter, Chief Sculptor, and Maker of Vases in Chief.” In his little spare time, he wrote poetry and dispensed philosophical advice. Imhotep can also boast of two accomplishments that eluded even Leonardo da Vinci. He was deified after his death and worshipped for many centuries, an honor accorded to hardly anyone besides the pharaohs. And today the comic book community gives him the credit for founding S.H.I.E.L.D., the Marvel Comics espionage and crime-fighting agency that became the basis for blockbuster movies such as Iron Man, Thor, and Captain America.

Wikimedia Commons  Egyptologists ascribe to Imhotep the design of the Pyramid of Djoser (the Step Pyramid) at Saqqara in Egypt in 2630 – 2611 BC. Wikimedia Commons  Jim Whiting has written a book on another great Egyptian leader -- Ramses the Great who lived about 1350 years after Imhotep. He fully lived up to the "Great" part of his name. His reign lasted for 67 years, the second longest in Egypt’s 3,000-year history. He had dozens of wives and more than 100 children, outliving many of them. He was a military leader who expanded the borders of his country. That resulted in decades of peace and prosperity for his people. He ordered huge statues of himself to be erected all over Egypt.

 Victoria, still in her widow's garb at age 80. When eighteen-year-old Victoria was crowned queen of England in 1837, the British wondered and worried who their very young queen would marry. Whoever he was, he would have power and influence, so the queen’s choice was critical. Victoria had many royal suitors and was getting advice from all directions about which alliance with which suitor would be most advantageous for England. But as the British quickly learned, their new queen had a mind of her own, and she had already picked Prince Albert of Saxe-Coberg, an area of what is now Bavaria, Germany. The British were shocked! Royalty often intermarried, so it wasn’t because Victoria and Albert were first cousins—her mother and his father were sister and brother—but because there was a great deal of anti-German sentiment in England at the time. Victoria didn’t care. He was her “dear Albert” and they were married in 1840 when they were both twenty-one. They loved each other and were determined that theirs would be a happy marriage. The odds were against this. Neither Albert nor Victoria had grown up in happy families—in fact, both had been exposed to mostly miserable marriages—and Victoria was spoiled, stubborn, and had a quick temper. Fortunately, Albert was a kind man who understood her well and knew how to be patient with her. That patience was put to the test many times as they raised their nine children. Victoria disliked being pregnant and wasn’t fond of babies and toddlers. But Albert provided balance. He doted on their four sons and five daughters and was closely involved in their care and education. The British public adored the royal family, and they came to love the scholarly Albert. He became a British citizen, was a wise political advisor to Victoria, and was active in public life. When he died from stomach problems in 1861 at age forty-two, the British grieved for him. Victoria went into deep mourning. Often called “the widow of Windsor,” she wore only black and lived a secluded life at Windsor Castle until her own death at age eighty-one. Today, her name and Albert’s grace London’s great Victoria and Albert Museum, known affectionately as the V&A. London is also home to several major public monuments that were commissioned by Victoria to honor her “dear Albert” and which serve as a reminder that theirs was truly a royal love story.  Marriage of Victoria and Albert Painting by George Hayter It has been said that Queen Victoria started a bridal custom of wearing a white wedding gown. Prior to that time royal brides wore elaborate dresses made especially for the occasion from gold or silver fabric sometimes embroidered with silken threads and embellished with semi-precious stones to show their wealthy status. Ordinary brides of the working class wore their “best dress” usually made in a dark and durable material.  Prince Albert and Queen Victoria with five of their children. The Prince Consort (26 August 1819 – 14 December 1861), lived long enough to see only one of his children married and two of his grandchildren born , while Queen Victoria (24 May 1819 – 22 January 1901) lived long enough to see not only all her grandchildren, but many of her 87 great-grandchildren as well.  Albert, Victoria and their nine children, 1857.

She was 15 pounds below minimum weight for the Navy when she joined, but she had a mighty mind. Admiral Grace Hopper changed the Navy. And your world. She graduated from Vassar College in math and physics then took a doctorate from Yale in math. She joined the Navy in World War II because it needed mathematicians to build the massive machines that computed tables of distance, gun elevation, projectile weight, windage and other factors for precise naval gunnery. Almost immediately she saw something other mathematicians didn’t see: computers could talk. They weren’t just number crunchers to Grace. They could do much, much more if they were given a simple language that would bring the advantages of gigantic computing power and enormous data storage to common uses. While working on the early computers she developed a “compiler,” a kind of translating machine that turned plain-language needs into a set of mathematical commands that retrieved number data from storage banks, performed thousands or millions of math operations, and provided real-world answers. In 1959 she was crucial in devising the first broad-based computer language, COBOL (COmmon Business Oriented Language). It is the root of the many computer operating systems we use today. Then-Captain Grace worked with the National Bureau of Standards to develop self-testing capabilities so a computer could “de-bug” itself. She coined this word when she extracted a fried moth disrupting one of her computers. She led the Navy away from a few giant computers to interconnected, smaller, scattered computers, opening the door to the internet. You are reading plain language words from my small computer on your web-connected small computer. Thank you, Grace. In 1985, at 79, she was promoted to rear admiral of the United States Navy Reserve. She said, “The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, ‘Try it.’ And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances.” She died in 1992 at 85. Admiral Grace Hopper received many awards and decorations but the Navy’s most sincere tribute came in 1996 when it named the guided missile cruiser DDG-70, USS Hopper. Naturally, its sailors call their ship “Amazing Grace.”
 Jan Adkins successfully tackles the art and science of 10,000 years of bridge building and imparts a lot of historical drama along the way. The process is given fascinating life in this accessible study, wonderfully illustrated by Jan Adkins himself. Ranging from ancient Rome to the present day, from simple log bridges to marvels of industrial technology, and from well-known landmarks to little-known feats of engineering and art, this book gives readers a new appreciation for that most familiar of structures, the bridge.
