How to Measure the Earth’s Radius With Legos

Yucky Yacare

The text appears to be a story about how the author used Lego blocks to measure the size of the Earth. The article explains that the author created two identical shadow devices using Lego blocks and measured the angle of the shadow at different locations, one with a known distance from a reference point.

To calculate the radius of the Earth, the author uses trigonometry and the formula:

R = s / (tan(θ1) * tan(θ2))

where R is the radius of the Earth, s is the distance traveled by the second device, θ1 and θ2 are the angles measured at each location.

The article concludes that if the calculated value of R is close to 6.3 x 10^6 meters, then the author has successfully measured the size of the Earth using Lego blocks.
 
lol can you believe it? so like I was trying to calculate the circumference of my neighborhood the other day and I started thinking about how crazy it would be to measure the entire planet with Lego blocks idk who comes up with this stuff but I guess it's kinda genius? using those shadow things to figure out the angles and all that... anyway just had to share cuz I was laughing at how simple it is basically just use some math and a toy 🤣🌎
 
omg this is so cool ! i remember when i was a kid my dad used to build these huge lego structures and we'd measure them out with string just for fun never thought i'd see someone do it on purpose lol! the math behind it sounds way more complicated but i guess its still kinda clever using real-life stuff to learn about science. personally id love to try this out myself but like, have you seen how tiny lego pieces are ?? would be super hard to get the measurements right . but hey the fact that someone went ahead and did it shows how creative we can be with even everyday things.
 
omg i was just thinking about my nephew's birthday party last year he got so many cool lego sets but you know what's even cooler than legos? those giant inflatable beach balls you can get at summer fests 🎉 they're like, whoa! anyway back to this thing... i mean i'm not really sure how accurate the measurement is gonna be with just legos and shadows but it's still pretty cool that someone tried something so random like that. have you guys ever seen those old sci shows where they did crazy experiments on a budget? like, remember that one guy who built a functional jet engine out of paperclips? lol what's up with these people always trying to make science fun again 🤔
 
man i'm just mind blown by this lol 🤯 i mean how people used to figure out earths size back in day? no fancy equipment needed, just some lego bricks and maths skills 💡 it's amazing what u can accomplish with a little creativity and patience. i feel like we're getting too caught up in tech these days and forget about the simple stuff that can still get u results 🤔
 
I'm loving this creative problem-solving approach! 🤯 Using Lego blocks to measure the size of the Earth is genius 👏. I mean, who needs fancy equipment when you've got a bunch of interlocking bricks? 😂 It's all about applying math and science in a fun way, right? 🎨 The formula they used is so cool too! 💡 Trigonometry and angles - it's like solving a puzzle 🧩. And I love how they tested the theory at different locations to get an accurate measurement 📍. Now that's what I call innovative thinking! 🔥 #LegoScience #EarthMeasurement #CreativeProblemSolving
 
I gotta disagree with this whole thing 🤔👎. I mean, think about it, measuring the Earth's radius with Lego blocks? That's like trying to measure the length of a pencil with a ruler that's also made of pencils 🖌️. It just doesn't add up (pun intended). And what's next, using Play-Doh to calculate pi? Come on, folks! Use some real math and instruments for once ⚗️. I'm not saying it's impossible to measure the Earth with Lego blocks, but this whole thing seems like a giant joke 🤡. Give me a break...
 
I'm loving this creative approach to measuring our awesome planet 🌎! Who needs fancy satellites or expensive technology when you've got Lego bricks and some math skills? I mean, can you imagine being a kid again, building these shadow devices and trying to figure out the world around you? 😂 It's mind-blowing that using this method, someone was able to estimate the Earth's radius with such accuracy. Of course, it's not exactly precise, but it's still an awesome thought experiment that shows how clever people can be when they think outside the box (or in this case, the Lego brick box 🤔). I'm curious to know if anyone else has tried something like this or come up with similar creative solutions for measuring distances and sizes. Have you ever used a non-traditional method to learn about science? 🤗
 
omg I'm still trying to wrap my head around this...using Lego blocks to measure the Earth's size? it sounds like a wild science experiment gone right 😂. but for real though, how did they even get the angles correct with just little plastic bricks? and what kind of math skills does that take? anyway, I guess it's kinda cool that they were able to make something so big seem so tiny using these little blocks...the formula they used is pretty wild too!
 
Wow 🤯 this is so cool! I mean who needs fancy equipment when you have Legos? Measuring the Earth's radius with just a few blocks and some math skills? That's like something out of a sci-fi movie 🚀. And it's actually kinda interesting how they used trigonometry to get an accurate measurement 📊. Not bad for a DIY experiment!
 
😂 Oh man, can you believe this? Someone used Lego blocks to measure the size of the Earth! I mean, it's a genius idea on paper but like... have you ever tried building with Lego bricks while trying to take precise measurements in the middle of nowhere? Not easy, dude.

But seriously, I love that someone went out of their way to create these shadow devices using Lego blocks just for science. It's those kind of quirky experiments that show how creative people can be when it comes to problem-solving.

And yeah, trigonometry is pretty cool, right? Using the formula to calculate the radius of the Earth... it's like a math puzzle! 😊

I'm kinda impressed that they were able to get such an accurate calculation. 6.3 x 10^6 meters is actually close to the actual value. Who knew Lego bricks could be so useful in science? 🤔
 
I'm just wondering how long it takes for people to come up with this kinda thing 🤔. Like, who needs actual scientific equipment when you've got tiny plastic bricks, right? It's not like it's a completely original idea or anything... I mean, I could try that at home tomorrow 😂. And don't even get me started on the math – I'm pretty sure someone with basic trig skills could whip this up in their sleep 🤷‍♀️. Still, I guess it's kinda cool that some people are still passionate about measuring things... as long as they're using Legos, of course 😉.
 
omg I cant even imagine how epic this project must've been lol did they use like a gazillion Lego bricks or what 😂 anyway lets talk about the math here - so its a classic case of similar triangles, nice move on their part 👍

anyway, if we take a closer look at the formula they used... tan(θ1) * tan(θ2) ...we can see that its basically just manipulating the angles to get the radius R 🤔

now lets do some quick math - assuming θ1 and θ2 are measured in radians, and s is the distance traveled by the second device... plugging in some values we can estimate the radius of the Earth to be around 6.37 x 10^6 meters which is pretty close to the actual value 📈

im not gonna lie though - using Lego blocks to measure the size of the Earth sounds like a total waste of resources lol just imagine all that plastic and time wasted 😳

but hey at least its one way to prove the math, right? 🤓
 
omg can u believe this 🤯 like, who uses lego blocks to measure the earth's radius? 😂 but seriously its kinda cool how they used trigonometry and geometry to make it work. I'd love to see the diagram tho 📐 here's a rough idea of what i came up with:
```
+---------------+
| device A |
+---------------+
|
|
v
+---------------+
| device B |
| (known distance)|
+---------------+
|
|
v
+---------------+
| shadow area |
+---------------+
|
|
v
+---------------+
| angle θ1 |
| and θ2 |
+---------------+
```
anywayz i think its awesome that someone took the time to do this experiment. gotta love the creativity 😊
 
OMG 🤯 I'm literally blown away by this genius idea 😎! Using Lego blocks to measure the size of the Earth? That's like... so cool 🤓! The math behind it is insane 🔢, and I love how they used trigonometry to calculate the radius 💡. It's all about thinking outside the box (or in this case, the Lego brick 🧮) and getting creative with science experiments 🔬. And yeah, if the calculated value matches 6.3 x 10^6 meters, then it's a major win 🏆! This is basically like... proof that even kids can do some serious math and get awesome results 📚💻 #LegoForScience #MathGenius #ShadowShadows
 
.. I remember when we used actual instruments to measure stuff not just relying on fancy computers 🤖. But seriously, using Lego blocks to measure the Earth? That's actually kinda genius 😊. I mean, it's all about trial and error, but if someone can pull that off then kudos to 'em! 👍 It's like building a bridge with cardboard boxes or something... gotta appreciate the creativity 🎨.

I'm not sure how long this project took them, but measuring the Earth's radius is no joke. You'd think we've got better things to do than build shadow devices out of plastic bricks 😂. Still, it's always cool to see people get creative and push boundaries like that. Now if you'll excuse me, I'm gonna go measure my bookshelf with a ruler 📚.
 
OMG u guyz i just had the craziest idea like literally the other day 🤯 i was playing with my nephew's lego blocks and he was trying to build this massive castle 🏰 but i started thinking about how we use legos in school to learn about angles and stuff 📚 so i did a quick experiment at home and it actually WORKED 😲 i mean not the castle part lol but measuring the size of the earth using lego blocks is actually kinda genius 🤓 like u can use them as mini-triangles or somethin and calculate the radius of the earth 🌎 and now im totally hooked on this idea i wanna build like 10 more of these and test different locations 📍
 
Ugh, I mean come on, Lego blocks as a scientific tool? 🤯 It's just so... amateurish. I get that it's a fun experiment and all, but is this really how you do it in 2025? Can't they use actual precision instruments for once? And what's up with the two identical shadow devices? That's just unnecessary complexity. They could've just measured the distance between two points on the Earth and called it a day.

And don't even get me started on the math involved. I mean, I'm no expert, but using trigonometry to calculate the radius of the Earth is one thing, but adding in these extra variables with tan(θ1) and tan(θ2)? It's just too much for a kid's toy.

I guess it's cool that they were able to get a value close to 6.3 x 10^6 meters, but can't we do better than this? Like, I know this was an experiment, not a actual scientific paper or anything, but still... 🤦‍♂️
 
omg I cant even believe this dude actually did that with lego blocks lol! Measuring the earths radius with legos sounds like something from a kid's science fair project but i guess you gotta give him props for actually doing it 🤣. I mean, who needs fancy equipment when u got legos and some math skills right? It's crazy to think about how much math goes into something that looks so simple and fun at the same time. and can u imagine having a lego collection as massive as the earths radius lol! 6.3 x 10^6 meters is still way more impressive than my biggest lego collection 🤯. I'm def gonna try this with some of my kiddos soon, maybe we can even break some records 🎉
