$An educational infographic titled 'The Sieve of Eratosthenes Explained', showing a step-by-step process to find all prime numbers up to 100 on a 10x10 grid. A column on the left details six labeled steps, including 'Circle 2, Cross Out Multiples' and 'Circle 3, Cross Out Multiples,' each with color-coded actions. On the 1-100 grid, numbers are circled in different colors or marked with colored 'X's according to these steps, effectively sifting out the composite numbers.At the bottom, a gold ribbon highlights the final set of prime numbers found: 2, 3, 5, 7, 11, and more, up to 97. The process is concluded when it is stated that 'Prime Numbers Remain up to $\sqrt{100}=10$'. To the right, a friendly cartoon illustration of Eratosthenes, wearing a toga, points to the grid and adds a final insight in a speech bubble: 'Only need to check up to the square root of the limit!'$

$A detailed educational infographic titled "How Eratosthenes Calculated the Circumference of the Earth," featuring a cross-section of the Earth and historical scenes from ancient Egypt. To the left, Eratosthenes stands in Alexandria measuring a $7.2^\circ$ shadow cast by a gnomon, while to the right, a deep well in Syene is shown with the sun directly overhead, casting no shadow.The central diagram uses geometric lines to show that the $7.2^\circ$ angle at the surface is equal to the angle at the Earth's center between the two cities. Four labeled steps explain the calculation: since $7.2^\circ$ is $1/50$th of a full circle ($360^\circ$), the distance between the cities (5,000 stades) is multiplied by 50 to find the total circumference of 250,000 stades.$

Introduction More than two thousand years ago, Eratosthenes Calculated the Circumference of the Earth using a simple but brilliant scientific

A realistic, wide-angle historical reconstruction of Eratosthenes at work in ancient Alexandria. The scholar, an older man with a grey beard and a white toga, sits at a rustic wooden table overlooking a bustling Mediterranean harbor with the famous Pharos Lighthouse in the background. He is focused on a large parchment map of the Nile, using a brass compass and calipers to measure distances between the cities of Alexandria and Syene. Surrounding him are the tools of a Hellenistic polymath: rolled papyrus scrolls, an armillary sphere, an hourglass, and a large wooden gnomon used for tracking shadows. To his left, a stone plaque is engraved with Greek text, and the warm sunlight suggests a clear, late morning in the 3rd century BCE.
