# 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 [<u>Walter Bislin's</u>](http://walter.bislins.ch/bloge/index.asp) Flat Earth Calculator [here](http://walter.bislins.ch/bloge/index.asp?page=Advanced+Earth+Curvature+Calculator). Tools like this are useful because they force a claim to become numbers. Once a claim becomes numbers, it can be tested.

### Recommended Topics

<div>- **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.

</div>### 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.

### Observation Project Ideas

These projects are practical ways to turn abstract arguments into direct experience.

- **Shadow pair experiment:** Compare stick shadows at two different latitudes near local solar noon.
- **Polaris altitude log:** Record Polaris altitude while travelling north or south.
- **Ship or building horizon observation:** Use known observer height, target height and distance, then compare with the curvature calculator.
- **Star trail photography:** Capture long exposures facing north, south and near the equator if travel allows.
- **Time-zone check:** Compare sunrise, sunset and solar noon between cities at different longitudes.

### Source Quality Checklist

- Does the source provide raw measurements, or only a conclusion?
- Are the location, time, altitude and equipment stated?
- Can the observation be repeated by an ordinary person?
- Does the explanation make a prediction before the result is known?
- Does it depend on a conspiracy to dismiss every conflicting measurement?
