July 17 - Yellow Pig Day
Yellow Pig Day is a mathematician's holiday celebrating "yellow pigs" and the number 17. It has been celebrated annually since the early 1960's primarily on college campuses and pirmarily by mathematicians.
The Yellow Pig was the brainstorm of mathematicians Michael Spivak and David C. Kelly in the early 1960's. They were students at Princeton University studying mathematics. History was made as they were listing interesting properties of the number 17. During this thought wave, the yellow pig was born.
Spend part of the day thinking and working in multiples of 17. And spend the other part of the day giving thought to yellow pigs.
July 3rd Week - Lyme Disease Awareness Week
Lyme disease, also known as Lyme borreliosis, was first recognized in Lyme, Connecticut, in 1975. Seven years later, its cause, a spirochete or spiral-shaped bacterium called Borrelia burgdorferi, was discovered by a researcher at the National Institute of Allergy and Infectious Diseases.
July 3 - August 11 - Dog Days of Summer
The Dog Days of Summer, also known as Canicular Days, are typically the hottest and most unhealthy days of the year. The traditional timing of Dog Days is the 40 days beginning July 3rd and ending August 11th coinciding with the heliacal (at sunrise) rising of Sirius. Sirius, the Dog Star, is visible with the rising Sun at this time of year. Ancients associated this sky picture with the hot days that coincided with it. Sirius is the brightest star in the constellation Canis Major (Greater Dog).
