¶ Educational Resources

An excellent place for quality materials that strengthen your understanding of our beautiful planet Earth. The best resources do more than state the answer; they show how we know.

¶ Start with Observation

Begin with things you can observe directly: the changing height of Polaris, lunar eclipses, star trails, time zones, shadows at different latitudes and the way ships or buildings disappear bottom-first with distance. Direct observation gives the rest of the evidence a place to land.

¶ Calculators

Check out Walter Bislin's Flat Earth Calculator HERE. Tools like this are useful because they force a claim to become numbers. Once a claim becomes numbers, it can be tested.

¶ Recommended Topics

• Basic geometry: angles, circles, spheres and scale.
• Astronomy basics: phases, eclipses, seasons and celestial poles.
• Atmospheric optics: refraction, mirages and horizon observations.
• Navigation: latitude, longitude, great-circle routes and GPS.
• Scientific reasoning: hypotheses, theories, predictions and falsifiability.

¶ How to Use This Wiki

Pick a claim, read the relevant science, then look for a prediction. A good explanation should help you understand what you would expect to see next. That is where real learning begins.

¶ Source Habits

When using any resource, prefer primary sources, full context and measurements over clipped images or anonymous summaries. A good educational path teaches you how to evaluate the next claim without needing someone else to pre-chew it.
