The Mind Blowing Physics Behind the Leaning Tower of Pisa!

The Leaning Tower of Pisa Literally Broke My Brain!

Guys, I'm still not over our Italy trip from a couple of year back! Like, I've seen a million pictures of the Leaning Tower of Pisa but seeing it in person was insane! It seriously looks like it's about to topple over any second, but this thing has been standing (well, leaning) for over 800 years! My physics brain was going crazy trying to figure out how!

So Why Is It Even Leaning??

Okay, so basically what happened is peak medieval engineering fail! They started building this tower in 1173 and literally didn't bother checking what was underneath. OOPS! Turns out the ground on the south side is just soft clay and sand - definitely not tower-supporting material!

By the time they finished just the first three floors, the whole thing was already tilting because the soil was compressing unevenly. The builders were probably like "well this is awkward" and then literally ABANDONED the project for almost 100 years! Can you imagine just leaving a half-built leaning tower and hoping it would figure itself out?? The dedication to procrastination is honestly impressive!

The Physics Is Actually Mind-Blowing! ⚖️

This is where it gets really cool though! The reason the tower hasn't fallen over is all about center of gravity. I learned in physics class that an object falls when its center of gravity moves outside its base of support. While I was there, I kept tilting my body to match the tower's 4-degree angle (yes, I measured it with an app because I'm that girl), and I could literally feel how my weight wanted to tip me over!

The tower's center of gravity is WAY off from the center of its base, but somehow, it's still just barely within the foundation's footprint - by like a few feet! It's basically been doing this insane balancing act for centuries. It's like when you lean way over to reach something and you're teetering on the edge of falling but somehow don't!

How Is This Thing Still Standing?

I was staring at this tower thinking "this defies everything I know about physics" but then our tour guide explained the genius behind it:

First, the tower is actually curved! When the builders came back after their century-long coffee break, they tried to fix the lean by making the new floors taller on the sinking side. If you really look at it (which obviously I did because I'm a total nerd), it's shaped like a giant banana! This curve helps redistribute the weight.

Also, the foundation is actually massive - way wider than the tower itself. This spreads out all that weight over a bigger area, which helps a ton with stability.

But here's the coolest part - in the 1990s, engineers literally performed surgery on this thing! They removed 70 tons of soil from under the high side to let the tower settle back a bit. That's like removing 70 grand pianos from underneath! This gave the tower another 300 years of stable leaning. Talk about job security for future engineers!

Italy = Life Changing Experience!

Honestly, standing next to this massive leaning structure made physics feel so real in a way that studying formulas never could. Also, can we talk about how I climbed ALL 294 steps to the top?? My legs were literally jello afterward, but the view was incredible!

And the gelato!! I had pistachio and dark chocolate after the climb, and it was probably the best thing I've ever tasted. Sometimes physics field trips have the best rewards!

I took like 300 photos from every possible angle because I'm that tourist, but whatever! Sometimes even massive engineering mistakes turn into something amazing that people travel across the world to see. There's definitely a life lesson in there somewhere!

Who else has been to Pisa? Please tell me your legs also felt dead after those stairs!
