As a celebration steeped in American history, you might expect it to be a day of remembering our forebears and displaying patriotism. However, in modern times, consideration of the first Thanksgiving is generally relegated to schoolchildren. Although that first celebration was a landmark moment in the history of America, beyond giving thanks for freedom and safety, you won't typically find the flag waving of the Fourth of July or Memorial Day. Instead, the holiday remains centered on family, friends, and food. Some see the holiday as a last bastion of non-commercialization. Beyond a few centerpieces and themed party supplies, Thanksgiving doesn't receive the same marketing push as Valentine's Day, Halloween, or especially Christmas. It feels more pure in this regard. However, the time and money required to create a traditional Thanksgiving spread doesn't make the day completely free of pressure. As a national holiday, Thanksgiving means a day free from school and work for most. Even television seems to conspire to bring families closer together, with spectacles such as the Macy's Thanksgiving Day parade, big football games, and themed marathons on numerous cable channels inviting everyone to gather 'round. Although giving thanks for the many blessings of life is easily interpreted as a religious sentiment, there is no particular creed or belief system associated with the holiday. A community might host an ecumenical service in honor of the holiday. Families often say a prayer over the food before beginning dinner. Churches sponsor holiday dinners as outreach to the poor and lonely. However, all of these actions are founded on the basic, secular premise of giving thanks. From preschoolers making handprint turkeys to adults remembering the most important people and moments in their lives, it is easy to answer, "Why do we celebrate Thanksgiving?" Like the Pilgrims did on that long-ago day, we all gather to give thanks for the many bounties life offers.

Eventhough parachutes seem to have been used in China since the 1100s and that Leonardo da Vinci of Italy had invented devices similar to parachutes nowadays, worldwide skydivers state that the French inventor André-Jacques Garnerin is the one to make the first parachute. In 1797 he jumped from a balloon over Paris using a parachute and kept on making other jumps in France and also in England.

In World War I , that is between 1914 and 1918, the military began using parachutes in their missions

end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy. LIGHT IN THE AIR Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the co

d after Lord John Rayleigh, an English physicist, who first described it in the 1870's.) WHY IS THE SKY BLUE? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by t

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Breakdance, breaking, b-boying or b-girling is a street dance style that evolved as part of the hip hop movement among African American and Puerto Rican youths in Manhattan and the South Bronx of New York City during the early 1970s

A breakdancer, breaker, b-boy or b-girl refers to a person who practices breakdancing.

Breakdancing may have begun as a building, productive, and a constructive youth culture alternative to the violence of urban street gangs.[1] Today, breakdancing culture is a remarkable discipline somewhere between those of dancers and athletes. Since acceptance and involvement centers on dance skills, breakdancing culture is often free of the common race and gender boundaries of a subculture and has been accepted worldwide.
