What Sets Us Apart

The Story Behind Our Specialties

Polaris (alpha UMi, alpha Ursae Minoris, Alpha Ursae Minors, commonly North Star, Northern Star or Pole Star, also Lodestar, sometimes Guiding star) is the brightest multiple star in the constellation and the 45th brightest star in the night sky. It is very close to the north celestial pole, making it the current northern pole star.

Because of its importance in celestial navigation, Polaris is known by numerous names. It became known as Polaris during the Renaissance, its name derived from the Latin Polaris "of/near the (north) pole".

Because alpha UMi lies nearly in a direct line with the axis of the Earth's rotation "above" the North Pole, Polaris stands almost motionless in the pole sky and all the stars of the Northern sky appear to rotate around it. Therefore, it makes an excellent fixed point from which to draw measurements for celestial navigation and for astrometry.

Justice, harmony and balance have been associated with the stars of Libra since ancient times. Libra is symbolized by the scales of the Roman goddess of justice, Astraea. Zebeneschimali, Libra's second brightest star, is one of the only green stars in the sky which can be seen clearly with the naked eye. Libra lies between Virgo and Scorpio on the zodiac band.

"Lyra", the Harp. It's easy to find Lyra, by first finding Vega – one of the brightest stars in the Earth night's sky. Look for Vega high overhead in mid-summer. Lyra looks like a small, lopsided square, with Vega just beside one of the corners of the square.

The legend tells the story of Orpheus, who was given a harp by God Apollo. Orpheus' music was sweeter than that of any other mortal man. It could soothe any savage, bring joy to the heart of the weary. It was even said that rivers changed course to stay near its beauty.

On March 22nd, 2007 the endodontic world lost an extraordinary professional. I lost a wonderful colleague and I lost a friend. Dr. Thomas Charles Dumsha, or Dr. D. as I called him, was an accomplished scholar and devoted mentor. Thom was memorable. Thom was genuine. Much of what I know about the specialty of endodontics and beyond the field of dentistry, Dr. D. Taught me. It is to him that I dedicate this office, TCD Endodontics.
