Lumen (unit)
The lumen (symbol: lm) is the SI unit of luminous flux, which quantifies the perceived power of visible light emitted by a source. Luminous flux differs from power (radiant flux), which encompasses all electromagnetic waves emitted, including non-visible ones such as thermal radiation (infrared). By contrast, luminous flux is weighted according to a model (a " luminosity function") of the human eye's sensitivity to various wavelengths; this weighting is standardized by the CIE and ISO. The lumen is defined as equivalent to one candela-steradian (symbol cd·sr): : 1 lm = 1 cd·sr. A full sphere has a solid angle of 4π steradians (≈ 12.56637 sr), so an isotropic light source (that uniformly radiates in all directions) with a luminous intensity of one candela has a total luminous flux of :. One lux is one lumen per square metre. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux e ...

Lumen (dating App)
Lumen was a dating app launched in 2018 for individuals over 50, co-founded by Charly Lester. Her app attracted more than 1.5 million users in less than a year. The app operated on a freemium model, allowing users to join for free while generating revenue through paid "premium" features. These features included advanced search filters, enabling users to refine potential matches based on criteria such as height, children, smoking habits, political views, and zodiac signs. Additionally, premium users could access features like viewing who had marked them as a "favorite." To address the issue of scammers, the platform employed artificial intelligence software and implemented a "selfie" registration system. This system required users to take a live photograph during registration, which was then compared to their uploaded profile pictures to verify authenticity. Lumen gained attention as part of MagicLab’s portfolio, which was acquired by Blackstone Inc. Blackstone Inc. is an A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Lumen (AKA-30)
USS ''Lumen'' AKA-30 was an in service with the United States Navy from 1944 to 1946. She was scrapped in 1964. History ''Lumen'' (AKA–30) was named after the minor planet 141 Lumen, which in turn was named after an 1867 book by astronomer Camille Flammarion. She was laid down by Walsh-Kaiser Co., Inc. Providence, R.I., 19 July 1944 under a Maritime Commission contract; launched 20 November 1944; sponsored by Mrs. Alex Walker; and commissioned 29 December 1944. After shakedown, ''Lumen'' departed Norfolk 29 January 1945, loaded troops and equipment at Pearl Harbor, then sailed for the Okinawa campaign, the largest amphibious operation of the Pacific War. Following brief stops in Eniwetok and Ulithi, the cargo ship arrived off Okinawa 17 April and under the threat of night air raids unloaded the men and cargo which were needed to secure this strategic base so close to Japan. Departing Okinawa, ''Lumen'' arrived Saipan 27 April and for the rest of the war shuttled cargo amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Lumens
Stellar, or Stellar Lumens (XLM) is a cryptocurrency protocol which allows transactions between any pair of currencies. The Stellar protocol is supported by the nonprofit Stellar Development Foundation (though this organization does not have 501(c)(3) tax-exempt status) which was founded in 2014. The for profit arm, Lightyear.io, was founded in 2017. History In 2014, Jed McCaleb, founder of Mt. Gox and co-founder of Ripple, launched the network system Stellar with former lawyer Joyce Kim. Before the official launch, McCaleb formed a website called "Secret Bitcoin Project" seeking alpha testers. The nonprofit Stellar Development Foundation was created in collaboration with Stripe CEO Patrick Collison and the project officially launched that July. Stellar received $3 million in seed funding from Stripe. Stellar was released as a decentralized payment network and protocol with a native currency, stellar. At its launch, the network had 100 billion stellars. 25 percent of those w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

141 Lumen
141 Lumen is a carbonaceous asteroid from the intermediate asteroid belt, approximately 130 kilometers in diameter. It is an identified Eunomia family#Interlopers, Eunomian interloper. Description It was discovered on January 13, 1875, by the brothers Paul Henry and Prosper Henry, but Paul is the one who was given the credit for this discovery. It is named for ''Lumen: Récits de l'infini'', a book by the astronomer Camille Flammarion. Richard P. Binzel, Richard Binzel and Schelte J. Bus, Schelte Bus further added to the knowledge about this asteroid in a light-curve survey published in 2003. This project was known as Small Main-belt Asteroid Spectroscopic Survey, Phase II or SMASSII, which built on a previous survey of the main-belt asteroids. The visible-wavelength (0.435–0.925 micrometre) spectra data was gathered between August 1993 and March 1999. Lightcurve data has also been recorded by observers at the Antelope Hill Observatory, which has been designated as an offi ...
