Through suffering and a sense of pride, the object of your demonstration will now likely feel that they have "been there" and "seen it" with "their own eyes". As they freeze and become exhausted at 3:00 AM while out walking the tundra, point out the low, non-setting (or non-rising) sun, and re-iterate your point in their heightened state of misery. Point to the very high sun and make your point when they are the most miserable. ![]() If the person in question is from a temperate latitude, take them to the tropics to feel the heat of the noon sun, preferably trapped out on a sailboat without water. There are numerous other ways of demonstrating that the Earth is round, or curved, at least, from analysing the center of gravity to simply observing the other round objects that are visible in space but I believe these illustrations to be the simplest to comprehend. Take a piece of card (A3, or so), attach two obelisks to the card by their bases and, with a light source, produce shadows - now, slowly bend the card so that it becomes convex (that is, the side with obelisks attached bulging out) and watch the effect. However, a demonstration can be achieved by a simple, local experiment (as opposed to having a party venture to a distant enough point): ![]() Shadows differ from place to placeĮratosthenes carried out this experiment to determine the circumference of the Earth, already assuming its spherical shape incidentally, the proof of such being consequential of the procedure. Luckily someone on the internet has already spent some time to help us here to make these easy to illustrate: 1. Simplest, you say? There are two that strike me as being simple to demonstrate. ![]()
