It was the annual homecoming dance at the local high school gym. Most of the young folk were out on the dance floor but a few young men and women lined the sides of the gym, hoping for a dance partner to ask them out onto the dance floor.
After waiting anxiously for quite a while, a rather awkward freshman finally got up the nerve to ask a pretty junior for a dance at the homecoming.
She gave him the once-over and said, "Sorry, I won't dance with a child."
"Please forgive me," responded the underclassman. "I didn't realize you were pregnant."

First Star Photograph

In 1850, the first photograph of a star was made. At Harvard Observatory (founded 1839), the observatory director, William Cranch Bond and a Boston photographer John Adams Whipple took a daguerreotype of Vega. (A daguerreotype used a copper base with a thin film of polished silver sensitized by iodine vapors to form a thin yellow layer of silver iodide. After the photograph was taken, the plate was developed in a current of magnesium vapor at 75ºC, which adhered to the light-struck parts of the plate. The plate was then fixed in sodium thiosulfate, and rinsed.) Overall, this process to take an image of a star or nebula took many hours of patient skill. Fortunately better photographic materials were later invented.
