The only known photograph of Frédéric Chopin, often incorrectly described as a daguerreotype. It is believed to have been taken in 1849 during the degenerative stages of his tuberculosis, shortly before his death. Chopin, a Polish pianist and composer of the Romantic era, is widely regarded as one of the most famous, influential, admired and prolific composers for the piano. He moved to Paris at the age of twenty, adopting the French variant of his name, "Frédéric-François", by which he is now known. Photo credit: Louis-Auguste Bisson

An 1877 photo of Louis Ducos du Hauron, a French pioneer of color photography. This is one of the earliest examples of subtractive color and one of the first to be printed on paper. The overlapping, subtractive yellow, cyan and red (magenta) image elements can clearly be seen at the edges. The CMYK color model, used for all color printing today, is an example of a subtractive color space .

An caliper, which is a caliper that uses a vernier scale to interpolate linear measurements. Vernier calipers can measure internal and external dimensions using, respectively, the uppermost and lower jaws, and also depths, using the depth probe (located at the right end). In this example, the first two digits (2.4) are decided by the location of the zero of the vernier scale in the centimeter scale, and the last digit (0.07), by the first line of the vernier scale that exactly matches a line of the centimeter scale above.

A test firing of twin linear XRS-2200 aerospike engines, originally built for the Lockheed Martin X-33, a next-generation, commercially operated reusable launch vehicle. The aerospike engine is a type of rocket engine that maintains its efficiency across a wide range of altitudes through the use of an aerospike nozzle. A vehicle with an aerospike engine uses 25-30% less fuel at low altitudes, where most missions have the greatest need for thrust. Photo credit: Marshall Space Flight Center
