As the title of the poem suggests, it was astronomical in focus, dealing with the stars. While it is uncertain whether the work ought to be called the Astronomia or Astrologia[3] either title would translate into English as "astronomy". All these sources do agree on one point: there survives from antiquity no expression of doubt as to whether Hesiod wrote the Astronomia.

Scholars of the 19th century, however, argued against Hesiodic authorship, going so far as to assign the poem to the Hellenistic Period following the work of Eudoxus. Most of the surviving content of the Astronomia concerns two star groups: the Pleiades and the Hyades.

The earliest likely reference to the Astronomia was no ringing endorsement. The author of the Epinomis states that no man should be called an astronomer if he, like "Hesiod", simply studied the risings and settings of the stars. From Wikipedia, the free encyclopedia. A Greek—English Lexicon9th ed.

Water resistance is just 30m, which is understandable for a watch of its complexity. Moving on, one thing some might notice is that there is no visible crown.

Of course, the eye is going to be drawn to the whimsical and elaborate world created within the dial. There is a lot to see, and also a lot that moves. To begin, the movement actually consists of three separate arms; one arm leads to a sub-dial that displays the time; another leads to a flying tourbillon; and finally, the third arm leads to a globe.

Though overshadowed, time is quite legible, the blued hour and minute hands are fairly large and contrast brilliantly against the 18k rose gold skeletonized sub-dial.

Horizontally, it makes a single rotation every 60 seconds. Vertically, it makes a rotation once every 10 minutes. Finally, the globe, which is made out of rose gold and blue lacquer, rotates on its own axis once every 60 seconds. It also makes a rotation around the dial once every 10 minutes because the entire structure or movement itself rotates clockwise and makes a rotation once every 10 minutes.

So in the middle of the dial is a large 1. These planets all rotate along with the movement, making a single rotation of the dial once every 10 minutes. The end result of all these rotating elements is stunning to behold and it does look as if you have a mini solar system spinning on your wrist.

The movement that enables all this is in-house caliber JCAM Comprising of components, the movement is unique because it is mostly constructed out of titanium. Since the mainspring has to drive so many rotating components, titanium is used to reduce the load on the mainspring.

Cosmology is a branch of astronomy. It studies the Universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. In the past, astronomy included disciplines as diverse as astrometrycelestial navigationobservational astronomyand the making of calendars. Nowadays, professional astronomy is often said to be the same as astrophysics.

Professional astronomy is split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena.

These two fields complement each other. Theoretical astronomy seeks to explain observational results and observations are used to confirm theoretical results. Amateurs play an active role in astronomy.

It is one of the few sciences in which this is the case. This is especially true for the discovery and observation of transient events. Amateur astronomers have helped with many important discoveries, such as finding new comets.


Astronomy should not be confused with astrologythe belief system which claims that human affairs are correlated with the positions of celestial objects. Various departments in which scientists carry out research on this subject may use "astronomy" and "astrophysics", partly depending on whether the department is historically affiliated with a physics department, [7] and many professional astronomers have physics rather than astronomy degrees.

In early historic times, astronomy only consisted of the observation and predictions of the motions of objects visible to the naked eye. In some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose.

In addition to their ceremonial uses, these observatories could be employed to determine the seasons, an important factor in knowing when to plant crops and in understanding the length of the year. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye. As civilizations developed, most notably in MesopotamiaGreecePersiaIndiaChinaEgyptand Central Americaastronomical observatories were assembled and ideas on the nature of the Universe began to develop.

Most early astronomy consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon and the Earth in the Universe were explored philosophically.

The Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it.Fireworks weren't the only thing to light up the sky over Independence Day weekend.
