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.
