Microspheres vary widely in quality, sphericity, uniformity, particle size and particle size distribution. One example of a compactness measure is sphericity formula 1. Those measurements however suffer from uncertainties in the deviation of the object from sphericity. The snub dodecahedron has the highest sphericity of all Archimedean solids. Epsilon provides a measure of departure from sphericity. It used an improved inflation system to improve the balloon's smoothness and sphericity. A revised inflation system was used for the balloon, to improve its smoothness and sphericity. By evaluating epsilon, we can determine the degree to which sphericity has been violated. This suggests that the data may violate the assumption of sphericity. When sphericity has been established, the F-ratio is valid and therefore interpretable. For simplicity and comparative purposes, the values are manually calculated assuming a sphericity of 1. The Almagest introduced the idea of the sphericity of heavens. Their mission was to determine the sphericity of the Earth. Some idea of the sphericity of the Earth seems to have been known to Parmenides. However, it contains clear proofs of the Earth's sphericity in the first chapter.
