Eyes on the SkyFeet on the Ground

Science can measure the passage of time with remarkable precision. Most of the clocks we use today are either mechanical (with springs, gears, pendula, etc.) or electronic (with batteries, computer chips, vibrating quartz crystals, etc.). Before mechanical clocks, sundials were commonly used. Sundials can still be seen on older buildings. The motion of the stars at night also mark time.

One Day

Today we know that the Earth is a mostly solid sphere that turns on its axis once every 24 hours.

The Moon, in turn, is a smaller solid sphere that revolves around the Earth about every 28 days. It reflects the light of the Sun and shows us its "phases", depending upon the relative position of the Sun, Earth, and Moon.

The Moon A Lunar Calendar

The motion of the stars can be used as a calendar of sorts. Even more conspicuous in the evening sky than the stars, however, is the Moon. The Moon shines very brightly with reflected sunlight. As the Moon orbits the Earth, we view it from different angles, and see its different phases.

What’s Your Sign?The astrological year is divided into the 12 signs of the zodiac, and the movements of celestial bodies are believed to bring about changes in the life of an individual, depending on the sign he is born under. Depending on the date of your birth, you will fall into one of the 12 signs of the zodiac, and if you're a believer, the implications are many. In every month of the western calendar, there exists a date where one zodiac sign gives way to the next, and a birthday on this day would mean that you're a cusp - and your personality traits will reflect a combination of the two signs.
