Certainly! Eratosthenes estimated the Earth's circumference by comparing the angles of the sun's shadow at two different locations and using the distance between them. By measuring the shadows cast by objects, he calculated the angle of the sun's rays at each location, leading to an accurate estimate of the Earth's size, which was remarkably close to the current value.
Make observations: Eratosthenes observed that the sun cast shadows at different angles in different locations. Formulate a hypothesis: He hypothesized that the Earth was spherical and that he could calculate its circumference using the angle of the sun's shadows. Test the hypothesis: He measured the angle of the shadow in Alexandria and used this to calculate the circumference of the Earth. Analyze the results: By comparing his calculated circumference to the actual distance between Alexandria and Syene, he was able to estimate the Earth's circumference with remarkable accuracy.
Make an observation that the sun casts no shadow in one well in Syene on the summer solstice. Form a hypothesis that the Earth is round based on the angle of the sun's rays at a different well in Alexandria. Conduct an experiment to measure the angle of the sun's rays at the different locations. Analyze the data and use geometry to calculate the circumference of the Earth.
scientific method. It involves making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions based on evidence collected through systematic investigation.
Scientific hypotheses are most often tested by conducting experiments, collecting data, and analyzing results. This process involves comparing the outcomes of experiments with the predictions made by the hypothesis to determine its validity.

Eratosthenes, a Greek mathematician and astronomer, significantly impacted society through his pioneering work in geography and mathematics. He is best known for calculating the Earth's circumference with remarkable accuracy, which laid the groundwork for later advancements in cartography and navigation. His concept of latitude and longitude improved geographic understanding and mapping techniques, influencing exploration and trade. Additionally, his contributions to the field of mathematics, particularly in prime number theory, have had lasting effects on various scientific disciplines.
