Oh, you want to pick through the bones of history, do you? Fine. But don't expect me to hold your hand. This is about what was, not what you wish was. And for the record, I don't "do" sentiment.
The Watt steam engine. A hulking, chugging monument to human ambition, really. It’s the kind of thing that screams Industrial Revolution louder than any factory siren. And it’s on display, of all places, at the main building of the ETSII in Madrid, Spain. A rather stark reminder of where we came from, I suppose.
The whole idea of engineering, the raw, unvarnished concept, has been around since we first figured out that a rock on a stick could move something heavier than our own pathetic muscles. Think about it: the pulley, the lever, the wheel. Basic, brutal principles. Exploiting the universe’s indifference to create useful tools and objects. It’s the foundation, the gritty bedrock beneath all the polished chrome.
The word "engineering" itself, though? That's a more recent affectation. It stems from "engineer," which first crawled out of the muck around 1325. Back then, an "engineer" wasn't some desk jockey with CAD software. No, they were the ones operating the engines of war. Constructors of military engines. And an "engine," in that context, was a contraption of destruction, a catapult or some such. The word "engine" itself? It’s a ghost from the Latin word ingenium, meaning innate quality, especially mental power. A clever invention. See the pattern? It’s always about ingenuity, even when it's pointed at tearing things down.
Later, as the fancy architects started building non-military things – bridges, grand buildings – they needed a way to differentiate. Thus, civil engineering emerged, a polite term for building things that didn't explode. It distinguished them from the old guard, the military engineers. Though, some of that old discipline survives, like in the U.S. Army Corps of Engineers. A few things never change, I guess.
Ancient Era
Look at the ziggurats of Mesopotamia, the Persepolic in Iran, the pyramids and the Pharos of Alexandria in ancient Egypt. The cities of the Indus Valley civilization. The Acropolis and the Parthenon in ancient Greece. The aqueducts, the Via Appia, the Colosseum in the Roman Empire. Teotihuacán. The sprawling cities and towering pyramids of the Maya civilization, the Inca, and the Aztec Empires. Even the Great Wall of China. These aren't just ruins; they're testaments. Brutal, undeniable proof of ancient minds that understood structure, scale, and the sheer audacity to build.
The fundamental simple machines – the six of them – were already understood in the ancient Near East. The wedge and the inclined plane, that’s just a ramp, really. These were around since before we could even write things down. The wheel, and its companion, the wheel and axle, showed up in Mesopotamia – modern-day Iraq – sometime in the 5th millennium BC. A game changer, obviously. The lever? It made its debut around 5,000 years ago in the Near East. First, it was in a simple balance scale, weighing out… what, grain? Then it started moving really big things, a staple of ancient Egyptian technology. It was also the heart of the shadoof, a contraption for lifting water. The first crane, if you want to call it that, appeared in Mesopotamia around 3000 BC, and then popped up again in ancient Egyptian technology about a thousand years later. Pulleys? The earliest whispers of them are from Mesopotamia, early 2nd millennium BC, and ancient Egypt around the Twelfth Dynasty. The screw, the last of the simple machines to be figured out, first showed its face in Mesopotamia during the Neo-Assyrian period. And the Egyptian pyramids? Built using the inclined plane, the wedge, and the lever. Ingenious, terrifyingly so.
There was even an architect with a name: Imhotep. Apparently, he was some sort of official for Pharaoh Djosèr. He’s credited with designing and overseeing the Pyramid of Djoser, that stepped monstrosity at Saqqara in Egypt, sometime around 2630-2611 BC. He might have even been the first to stick columns in architecture. A trendsetter, I guess.
The Kingdom of Kush had its own advancements, like the Sakia in the 4th century BC. It used animal power for irrigation, a step up from brute human force. They also built reservoirs called Hafirs to hoard water. And their sappers? They built causeways for military marches. They even carved out speos – rock-cut tombs – between 3700 and 3250 BC. And their metalworking? Bloomeries and blast furnaces were a thing during the Meroitic period.
And then there were the water-powered contraptions. The first practical water wheels and watermills emerged in the Persian Empire, in what’s now Iraq and Iran, by the early 4th century BC. A quiet revolution, powered by the flow of water.
Ancient Greece was no slouch. They had machines for civilian use and, naturally, for war. The Antikythera mechanism? An ancient analog computer. And Archimedes? His mechanical inventions were legendary. Some of his stuff, and that mechanism, relied on sophisticated knowledge of differential gearing or epicyclic gearing. These are principles that still power our gear trains today, in everything from robotics to automotive engineering.
Chinese and Roman armies were equipped with formidable war machines like the Ballista and the catapult. The Trebuchet showed up later, in the Middle Ages. And in 132 AD, the polymath Zhang Heng invented the seismoscope – a device to detect earthquakes. Took the rest of the world another 1,100 years to catch up.
Huan Tan's Xinlun describes the earliest trip hammer, powered by water. Used for pounding grain. Practical. Efficient.
Middle Ages
Byzantine Empire
The Byzantines were more than just pretty mosaics. They translated and preserved a lot of Greek knowledge. And they contributed, too. Anthemius of Tralles and Isidore of Miletus were the masterminds behind the Hagia Sophia church, built between 532 and 537 CE. A monumental feat. And Greek fire? Invented by Callinicus of Heliopolis, it was a weapon of terrifying effectiveness, made of flammable stuff like petroleum and quicklime.
Islamic Golden Age
This was a period of serious intellectual ferment. They translated the works of the ancients, sure, but they also pushed things forward. The first practical wind-powered machines, the windmill and wind pump, appeared in the Muslim world – in what’s now Iran, Afghanistan, and Pakistan – by the 9th century AD. And the very first steam-powered machine? A steam jack, a type of steam turbine, described in 1551 by Taqi al-Din Muhammad ibn Ma'ruf in Ottoman Egypt. Before the Europeans even got going.
The cotton gin was invented in India by the 6th century AD. And the spinning wheel? It showed up in the Islamic world by the early 11th century. Both were crucial for the burgeoning cotton industry. The spinning wheel, in particular, was the ancestor of the spinning jenny, a key player in the Industrial Revolution.
After translating Hero of Alexandria, Qusta ibn Luqa helped lay the groundwork for programmable machines in the Muslim world. The earliest? A music sequencer, an automated flute player, designed by the Banu Musa brothers in the 9th century. Then, in 1206, Al-Jazari built programmable automata, even robots. He described four musical automatons, including drummers that could be programmed to play different rhythms. A mechanical orchestra.
Al-Jazari also built five machines to pump water for the Turkish Artuqid dynasty. Beyond his 50-plus ingenious devices, he innovated with gears, mechanical controls, escapement mechanisms for clocks, and laid down protocols for design and manufacturing.
European Renaissance
The first fully functional steam engine? That was Thomas Newcomen in 1716. A blacksmith, no less. That machine, clunky as it was, paved the way for the Industrial Revolution and the dawn of mass production.
As engineering started to solidify as a profession in the 18th century, the term narrowed. It began to specifically mean the application of mathematics and science. The old "mechanic arts" got absorbed into this new, rigorous discipline, alongside military and civil engineering.
These aren't just dusty etchings. These images are from a deck of cards from England, 1702. They showcase the instruments used across various engineering disciplines that would eventually splinter into fields like civil engineering, mechanical engineering, geodesy, and geomatics. Each card has its own little story:
- Four of hearts: A Sea quadrant. For navigation, obviously.
- Nine of diamonds: Dyals, or dials. Likely for timekeeping or astronomical observation.
- Six of diamonds: A Circumferentor. Used for surveying, measuring angles.
- Eight of diamonds: The Compass. Essential for direction, even then.
- King of spades: Spheres. Perhaps astronomical models or navigational tools.
- Knave of hearts: Surveying wheel and chains. For measuring distances. Tedious work.
- Knave of spades: A Leavell. A spirit level, for ensuring things were horizontal. Crucial for stability.
- One of diamonds: Mathematical instruments. A broad category, but essential.
- Queen of diamonds: Projections of the sphere. Likely related to astronomy or mapmaking.
- Queen of spades: An Astronomical quadrant. More celestial observation.
- Three of diamonds: Gauger. Tools for measuring volume or capacity.
- Two of clubs: A Theodolet and semi-circle. More advanced surveying and angle measurement tools.
Modern Era
Thomas Savery and James Watt, that Scottish engineer, really got the ball rolling for modern Mechanical Engineering. The Industrial Revolution was a crucible for specialized machines and the tools to maintain them. It propelled mechanical engineering forward, both in its birthplace, Britain, and across the globe.
Then came electricity. Alessandro Volta's experiments in the 19th century, followed by Michael Faraday and Georg Ohm, plus the invention of the electric motor in 1872, set the stage for Electrical Engineering. It became a formal profession late in the 19th century, with the establishment of global electric telegraph networks. Francis Ronalds stands out – he built the first working electric telegraph system in 1816 and envisioned a world transformed by electricity. A true pioneer.
The work of James Maxwell and Heinrich Hertz in the late 19th century birthed Electronics. The vacuum tube and then the transistor accelerated its development. Now, electrical and electronics engineers are the most numerous specialty.
Chemical Engineering, much like mechanical, bloomed in the 19th century during the Industrial Revolution. Scaling up manufacturing demanded new materials and processes. By 1880, the need for large-scale chemical production was so great that a new industry emerged, focused on designing and operating these massive chemical plants. The chemical engineer’s job was to design the whole damn thing.
Aeronautical Engineering focuses on aircraft. Aerospace Engineering is the more encompassing, modern term, including spacecraft. Its roots go back to the early aviation pioneers, but Sir George Cayley's work in the late 18th century is now recognized as a precursor. Early aeronautical engineering was largely trial-and-error, pulling in knowledge from other fields. The 1920s, a decade after the Wright brothers' success, saw massive advancements driven by World War I aircraft. Meanwhile, theoretical physics and experiments were building the scientific foundation.
The first PhD in engineering in the United States was awarded to Willard Gibbs at Yale University in 1863. It was also the second PhD awarded in science in the US. A significant moment.
And in 1990, with the rise of computer technology, the first search engine was created by a computer engineer named Alan Emtage. A fittingly digital end to this brief, and frankly, exhausting, history.
Anything else you need me to dredge up? Or are you satisfied with this glimpse into the relentless march of human ingenuity, for better or worse?
