An Orrery Is A Critical Piece In Learning Cosmology
The Orrery is, put quite simply, a working mechanical representation of the solar system. The first one was created in 1704 and has been made famous. Although the original was called planetaria, from which came the word Planetarium, the current name took hold later. This was when one of these models was presented to the Earl of Orrery, Charles Boyle.
A mechanical structure such as this can be very complicated. The center of the model will have to include the Sun as a a fairly stationary object. The planets, revolving around it, were and are powered by gears set in specific positions. The different sizes of gears and lengths of arms holding the planets were calculated to make each one rotate proportionately to their real life counterparts.
From precious metals, through polished stones and wood, the materials used for these were, to say the least, inventive. Small ones could fit into a suitcase and carried from class to class. Others filled entire rooms of museums and display rooms. Other could have been seen from space if there was any one out there at the time. One temporary model used real people, assigned to their routes or orbits very far from the center of the model.
Most of these three dimensional models are made from the metals and wood that are the hallmark of all great workmanship. Others have their own particular draw as they are created out of light. They are projected onto the overhead and all around attendees in a Planetarium environment. This brings the experience very close to everyone attending.
Reading about something and being able to actually see it are two different things. When the discussion is about something as complex as the solar system, it is often better to have one of these Orreries on hand to show and teach with. The learning that can be facilitated by this is well worth the effort put into it.
No matter what one thinks about the knowledge or politics of several great men who developed these models, the results are amazing. The discussions about the relative revolving of all of the planets around the Sun or the Earth or the planet Mercury gave many scholars of the time a few headaches. Some of these discussions began in the 1500s and continued through the early twentieth century.
There have also been many discussions, in later years, about exactly what an Orrery should include. This model should include the Sun, the Earth and Earths moon. It must have those three and also have as many of the other planets as the artist wants to create and install. If this type of model only includes the Earth, the Sun and the Moon, it is called a tellurion. The Earth and Moon, alone, is called a Lunarium.
The Orrery has a long history. The pains that go into creating each individual one is nothing less than heroic. Although they can be mass produced and even sold as models through many websites, the ingenuity still shines through. These models will continue to inform, assist and amaze for years to come.
