USRA 2-8-8-2
The USRA 2-8-8-2 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-8-2 wheel arrangement in the Whyte notation, or (1'D)'D1' in UIC classification. A total of 106 locomotives were built to this plan for the USRA; postwar, it became a de facto standard design.
Lighting
In order to specifically measure the amount of light entering the eye, personal circadian light meter called the Daysimeter has been developed. This is the first device created to accurately measure and characterize light (intensity, spectrum, timing, and duration) entering the eye that affects the human body's clock.
USRA Heavy Mountain
The USRA Heavy Mountain was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification.
Light-year
The light - year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles. As defined by the International Astronomical Union (IAU), a light - year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word ``year '', the term light - year is sometimes misinterpreted as a unit of time, as a year is a unit of time equivalent to approximately 365 days.
USRA Light Mikado
The USRA Light Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light freight locomotive of the USRA types, and was of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification.
Old Ironsides station
Old Ironsides is a light rail station operated by Santa Clara Valley Transportation Authority (VTA), located in Santa Clara, California. Old Ironsides is served by the Mountain View–Winchester light rail line.
United States Railroad Administration
The United States Railroad Administration (USRA) was the name of the nationalized railroad system of the United States between December 28, 1917, and March 1st, 1920. It was possibly the largest American experiment with nationalization, and was undertaken against a background of war emergency.
USRA Heavy Mikado
The USRA Heavy Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration (USRA), the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. A total of 233 locomotives were built to this plan for the USRA; postwar, it became a "de facto" standard design, which was built to the total of 957 locomotives including the USRA originals and all subsequent copies.
USRA Light Mountain
The USRA Light Mountain was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification.
USRA Light Santa Fe
The USRA Light Santa Fe was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. These locomotives were of 2-10-2 wheel arrangement in the Whyte notation, or 1′E1′ in UIC classification; this arrangement was commonly named "Santa Fe" in the United States. At the time, the Santa Fe was the largest non-articulated type in common use, primarily in slow drag freight duty in ore or coal service.
USRA 0-6-0
The USRA 0-6-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light switcher of the USRA types, and was of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification.
Cape May–Lewes Ferry
The ferry trip takes approximately 80 minutes and provides a view of three lighthouses: the Cape May Light in New Jersey, and the Harbor of Refuge Light and Delaware Breakwater East End Light near Lewes.
Remote control
The first remote intended to control a television was developed by Zenith Radio Corporation in 1950. The remote, called ``Lazy Bones '', was connected to the television by a wire. A wireless remote control, the`` Flashmatic'', was developed in 1955 by Eugene Polley. It worked by shining a beam of light onto a photoelectric cell, but the cell did not distinguish between light from the remote and light from other sources. The Flashmatic also had to be pointed very precisely at the receiver in order to work.
Tehachapi Pass
Tehachapi Pass is a mountain pass crossing the Tehachapi Mountains in Kern County, California in the United States. Traditionally, the pass marks the northeast end of the Tehachapis and the south end of the Sierra Nevada range.
Gamburtsev Mountain Range
The Gamburtsev Mountain Range (also known as the Gamburtsev Subglacial Mountains) is a subglacial mountain range located in East Antarctica, just underneath the lofty Dome A, near the Southern Pole of Inaccessibility. The range was discovered by the 3rd Soviet Antarctic Expedition in 1958 and is named for Soviet geophysicist Grigoriy A. Gamburtsev. It is approximately long, and the mountains are believed to be about high, although they are completely covered by over of ice and snow. The Gamburtsev Mountain Range is currently believed to be about the same size as the European Alps, and, as of 2008, it is unknown how the mountains were formed, though the current speculated age of the range is over 34 million years and possibly 500 million years. Current models suggest that the East Antarctic ice sheet was formed from the glaciers that began sliding down the Gamburtsev range at the end of the Eocene. Vostok Subglacial Highlands form an east extension of Gamburtsev Subglacial Mountains.
USRA Heavy Pacific
The USRA Heavy Pacific was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard heavy passenger locomotive of the USRA types, and was 4-6-2 wheel arrangement in the Whyte notation, or 2′C1′ in UIC classification.
