John Harrison & Nevil Maskelyae, “The Principles of Mr. Harrison’s Time Keeper“, 1767 was the topic of an earlier blog post on the nautical, “pocket watch”.
Here I present the “mariner’s compass” in William Gilbert’s, “De Magnete”, 1600 AD.
Shen Kuo, “Dream Pool Essays’, 1088 AD. was the description of the “magnetic, needle compass” use in “celestial navigation” in history.
Outside of China, Alexader Necham in 1187 Europe gave a description of “mariner’s compass” in celestial navigation for Europeans.
William Gilbert, “De Magnete”, 1600 AD is a treatise on “geomagnetism” the force. William Gilbert’s discovery of “‘magnetic force” of the planet Earth was a historic event for the Scientific Movement. Regiomontanus established the first scientific printing press in 1472.
Then 128 years later, William Gilbert made the astrophysical discovery of “geomagnetism”. “Gravitation” was the next astrophysical, force discovery inspired by William Gilbert, “De Magnete”, 1600 AD. of Isaac Newton, “The Principia: The Mathematical Principles of Natural Philosophy”, 1687 AD.
Astrophysical forces discovered, “gravity” and “electro-magnetism” with “nuclear” are enough for “Physical Cosmology” theory. In an lexicography, William Gilbert is known for coining the term “electricity”.
