The Sun Changes its Position in Space…by August TischnerThe Sun changes its position in space, therefore it cannot be regarded as being “in a condition of rest.”Si concedimus, eos, qui corpora in mundi spatio moveri eademque non moveri posse dicunt, insulsa loqui, praesumere non licet hominem astronomum talem sententiam elocuturum utque eam demonstraret operam daturum esse. 1883ContentsDedicationIllustration: Nicolaus Copernicus.
