Spacetime
In physics, spacetime is a mathematical model that combines the three dimensions of space and one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur. Until the 20th century, it was assumed that the three-dimensional geometry of the universe (its spatial expression in terms of coordinates, distances, and directions) was independent of one-dimensional time. The physicist Albert Einstein helped develop the idea of spacetime as part of his theory of relativity. Prior to his pioneering work, scientists had two separate theories to explain physical phenomena: Isaac Newton's laws of physics described the motion of massive objects, while James Clerk Maxwell's electromagnetic models explained the properties of light. However, in 1905, Einstein based a work on special relativity on two postulates: * The laws of physics are invariant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potez 4D
The Potez 4D was a four-cylinder, inverted inline aircraft engine. It was first built shortly before World War II, but did not enter full production until 1949. Like the other D-series engines, the cylinders had a bore of 125 mm (4.9 in) and a stroke of 120 mm (4.7 in). Power for different models was in the 100 kW-190 kW (140 hp-260 hp) range.

Ring Finger
The ring finger, third finger, fourth finger, leech finger, or annulary is the fourth digit of the human hand, located between the middle finger and the little finger. Sometimes the term ring finger only refers to the fourth digit of a left-hand, so named for its traditional association with wedding rings in many societies, although not all use this digit as the ring finger. Traditionally, a wedding ring was worn only by the bride or wife, but in recent times more men also wear a wedding ring. It is also the custom in some societies to wear an engagement ring on the ring finger. In anatomy, the ring finger is called ''digitus medicinalis'', ''the fourth digit'', ''digitus annularis'', ''digitus quartus'', or ''digitus IV''. In Latin, the word ''anulus'' means "ring", ''digitus'' means "digit", and ''quartus'' means "fourth". Etymology The origin of the selection of the fourth digit as the ring finger is not definitively known. According to László A. Magyar, the names of the ...

Air Sinai
Air Sinai ( ar, سيناء للطيران ') was an airline based in Cairo, Egypt. It operated as a 'paper airline' for parent company Egyptair under a wet lease-like agreement to serve flights exclusively between Egypt and Israel. History The Egypt–Israel peace treaty signed in March 1979 stipulated that there must be active civilian aviation routes between Egypt and Israel. To fulfill the treaty, Air Sinai was established in 1982 to fly scheduled services between Egypt and Israel (on routes previously flown by Nefertiti Aviation), which for political reasons could not be handled by parent company Egyptair. Services started using a Boeing 737-200 leased from Egyptair and new routes from Egypt's tourist destinations followed. By the mid-1980s a Fokker F27 Friendship was also in use on these services. During 1982, a Boeing 707-320C was leased and operated on behalf of Egyptair on their flights to Europe, especially twice weekly from Cairo to Copenhagen. Due to the tense Egypt ...

4-Digits
4-Digits (abbreviation: 4-D) is a lottery in Germany, Singapore, and Malaysia. Individuals play by choosing any number from 0000 to 9999. Then, twenty-three winning numbers are drawn each time. If one of the numbers matches the one that the player has bought, a prize is won. A draw is conducted to select these winning numbers. 4-Digits is a fixed-odds game. Magnum 4D is the 1st legalised 4D Operator licensed by the Malaysian Government to operate 4D. Soon thereafter, other lottery operators followed suit, as this is a very popular game in Singapore and Malaysia. The recently launched Daily Derby 4D Blue and Green and 5D jackpots of WTL-M is also growing popular now. Singapore Pools is the sole provider of gambling games in Singapore. 4-D and lottery 6/49 are two of the most popular. A similar 4-D game with its prize structure fully revealed can be found in Taiwan. 4-Digits is somewhat similar to " Pick 4" in the United States, Canada 5-Digits "Pick 5", and Jackpot in Germany an ...

4D (train)
The 4D was a prototype double deck electric multiple unit built for the Public Transport Corporation in Victoria, Australia, for operation on the Melbourne railway system. It remains the only double deck train to have ever operated in Melbourne. The train's name stood for "Double Deck Development and Demonstration." Depending on sources, the intention was for this train to be the demonstration unit for a future order of either 20 or 50 extra sets, had the tests been successful. Design A tender for the design and construction of 19 double-deck trains was opened on 24 November 1989. The number of carriages to be built was at the discretion of the builder, however it had to comply with capacity and length requirements. By 11 April 1990, when the tender was closed, a number of tenders were received, including from Comeng and A Goninan & Co. However, the project was stopped by the State Government, due to financial constraints. Instead, The Met was granted approval to acquir ...

4-D (psychedelic)
4-D (3,5-methoxy-4-trideuteromethoxyphenethylamine) is a lesser-known recreational psychedelic drug. It is one of the few drugs that bears deuterium. It is a deuterated analog of mescaline. It may be prepared either as a sulfate salt or a hydrochloride salt. 4-D was first synthesized by Alexander Shulgin. In his book '' PiHKAL'', the dosage is listed as approximately 200–400 mg for the sulfate salt, and 178–356 mg for the hydrochloride salt. 4-D lasts for approximately 12 hours. It causes closed-eye visuals, mild open-eye visuals, color distortion, and mydriasis. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-D.
