The Eiffel Tower


Since today is March 31, it’s the perfect time for a crash course on a marvel of engineering that was actually inaugurated on this very day back in 1889.

The Eiffel Tower: The "Temporary" Eyesore

Most people know the Eiffel Tower as the quintessential symbol of Paris, but its journey from a 20-year permit to a permanent global icon is full of surprises.

1. It was supposed to be demolished

The tower was built as the entrance arch for the 1889 World's Fair (celebrating the 100th anniversary of the French Revolution). Gustave Eiffel only had a permit to keep the tower standing for 20 years. It was slated to be scrapped in 1909, but it was saved because it proved to be a perfect giant antenna for the new technology of radio transmission.

2. Parisians hated it

When it was first built, the "Iron Lady" was considered a hideous industrial scar on the city's skyline. A famous group of artists and writers (including Guy de Maupassant) signed a "Protest Against the Tower of Monsieur Eiffel," calling it a "gigantic black smokestack."

Fun Fact: Maupassant reportedly ate lunch at the tower’s restaurant every day—not because he liked the food, but because it was the only place in Paris where he didn't have to look at the tower.

3. Engineering Feats

  • Expansion: Because it is made of puddled iron, the tower actually grows in the summer. Thermal expansion can cause the metal to swell, making the tower up to 15 centimeters (6 inches) taller in the heat.

  • The Stairs: On the day it opened (March 31, 1889), the elevators weren't finished. Gustave Eiffel himself walked up all 1,710 steps to unfurl the French flag at the top.


Why it matters today

The Eiffel Tower paved the way for modern skyscrapers by proving that a "curtain wall" of iron could withstand massive wind pressure without the need for thick stone walls. It wasn't just a monument; it was a laboratory for aerodynamics and meteorology.

Agentic Workflows


On this day in 1858, Hyman Lipman patented the first pencil with an attached eraser. While that sounds simple, it mirrors exactly what we are seeing in technology today: the transition from "standalone tools" to "integrated systems."
