Princeton, Massachusetts
Princeton is a town in Worcester County, Massachusetts, United States. It is bordered on the east by Sterling and Leominster, on the north by Westminster, on the northwest by Hubbardston, on the southwest by Rutland, and on the southeast by Holden. The preeminent landmark within Princeton is Mount Wachusett, which straddles the line between Princeton and Westminster but the entrance to which is within Princeton.

Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

Daguerreotype
Daguerreotype (; french: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process. Invented by Louis Daguerre and introduced worldwide in 1839, the daguerreotype was almost completely superseded by 1860 with new, less expensive processes, such as ambrotype ( collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist polished a sheet of silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposed it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; made the resulting lat ...

Francis Thomas Bacon
Francis Thomas Bacon OBE FREng FRS (21 December 1904 – 24 May 1992) was an English engineer who in 1932 developed the first practical hydrogen–oxygen fuel cell. It is used to generate power for space capsules and satellites. Life and works Francis Thomas Bacon was born in 1904 at Ramsden Hall, Billericay, Essex, England. An engineer at Trinity College, Cambridge, in 1932 he developed the fuel cell which was used as part of the Apollo moon project in the 1960s. Fuel cells were first demonstrated by Sir William Robert Grove in 1839, but his invention lay largely dormant for over 100 years until it was revived by Bacon. The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. The U.S. President Richard Nixon welcomed Bacon to the White House, and told him; "Without you Tom, we wouldn't have gotten to the moon.” After the successful lu ...
