Properties of water

Water (H
2O) is the most abundant compound on Earth's surface, covering 70 percent of the planet. In nature, water exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some properties may vary from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for all life on Earth. Water makes up 55% to 78% of the human body.

H2O (software)

H2O is open-source software for big-data analysis. It is produced by the start-up H2O.ai (formerly 0xdata), which launched in 2011 in Silicon Valley. The speed and flexibility of H2O allow users to fit hundreds or thousands of potential models as part of discovering patterns in data. With H2O, users can throw models at data to find usable information, allowing H2O to discover patterns. Using H2O, Cisco estimates each month 20 thousand models of its customers' propensities to buy.

H2O's mathematical core is developed with the leadership of Arno Candel; after H2O was rated as the best "open-source Java machine learning project" by GitHub's programming members, Candel was named to the first class of "Big Data All Stars" by Fortune in 2014. The firm's scientific advisors are experts on statistical learning theory and mathematical optimization.

The H2O software runs can be called from the statistical package R and other environments. It is used for exploring and analyzing datasets held in cloud computing systems and in the Apache Hadoop Distributed File System as well as in the conventional operating-systems Linux, Mac OS, and Microsoft Windows. The H2O software is written in Java, Python, and R. Its graphical-user interface is compatible with four popular browsers: Chrome, Safari, Firefox, and Internet Explorer.

H2O (H2O album)

H₂O is the first album released by H₂O. It was released on June 25, 1996. The CD was recorded and mixed in 3 days. H2O did a video for "Family Tree" in the fall of 1996.

Personnel

Dove (steamboat)

The steamboat Dove operated in the late 1890s and early 1900s as part of the Puget Sound Mosquito Fleet and also for a time on Grays Harbor. She was later converted into a tug. The Dove (ex-Typhoon) should not be confused with the Virginia III (ex-Typhoon).

Construction

Dove was originally built in 1889 in Portland, Oregon for ferry service under J.B. Montgomery, and launched under the name Typhoon.

Operations

In 1891, J.B. Montgomery sold Typhoon to George Emerson at Grays Harbor, who in turn sold the vessel a short time later to C.O. Lorenz, who brought her to Puget Sound and placed her on the Tacoma-Henderson Bay route. In 1903, she was acquired by Matthew McDowell, who rebuilt the vessel and placed her on the Seattle-Tacoma-East Pass route under the name Dove.

Later operations

In about 1916, McDowell sold Dove to Washington Tug & Barge Co. of Seattle, and Dove thereafter served as a tug.

Hawk and Dove

Hawk and Dove are a superhero team that appear in DC Comics. Created by Steve Ditko and Steve Skeates and debuting in Showcase No. 75 (June 1968) during the Silver Age of Comic Books, the duo has existed in multiple incarnations over the years across several eponymous ongoing series and mini-series, and has also appeared in a number of recurring roles and guest-appearances in titles such as Teen Titans, Birds of Prey, and Brightest Day. The most prominent incarnations have been the original pairing of teenage brothers, the temperamental and militant Hank Hall (Hawk I) with the well-read and pacifistic Don Hall (Dove I), as well as the current teaming of Hank Hall with Dawn Granger (Dove II), an unrelated young woman who assumes the role of Dove in Hawk and Dove (vol. 2) No. 1 (October 1988) following Don's death in 1985's Crisis on Infinite Earths maxi-series.

The central concept which was originally inspired by the emerging political divides of the 1960s (see war hawks and war doves) traditionally revolves around two young heroes with contrasting personalities and diametrically opposed ideologies who, by speaking their super-heroic aliases, are transformed and granted power sets of heightened strength, speed, and agility. With Dove representing reason and nonviolence and Hawk representing force and aggression, they complement one another and find a state of balance in order to effectively combat evil. With Dawn's introduction, it was revealed that Hawk and Dove receive their powers from the Lords of Chaos and Order, respectively, and that their powers are mystic in origin.

Moony

Moony (born Monica Bragato, born 27 September 1980) is a musician from Italy. She was the vocalist on DB Boulevard's hit single "Point of View", as well as on her own single "Dove (I'll Be Loving You)".

Raised in Venice, Moony was first noticed singing in the Venetian club scene and was asked to provide vocals for a number of songs by DJ and producer Cristiano Spiller. The first single was "Positive", in 1998, sampled from the "Physical", song of Olivia Newton-John, and the second single with Spiller was "Batucada" (1999). She also featured in the project, Angel Moon, in the song "He's All I Want", released in 1998.

Her first major success was "Point of View" as part of the group DB Boulevard. That song became popular across the European dance music scene, and entered the UK Singles Chart at number three. It earned DB Boulevard the distinction of being the first Italian music group to be nominated in the MTV Europe Music Awards. From there on, she launched her solo career. The first single "Dove (I'll Be Loving You)" was a commercial success and entered the UK Singles Chart at number nine. She released her debut album Lifestories in 2003.

White and Black in chess

In chess, the player who moves first is referred to as "White" and the player who moves second is referred to as "Black". Similarly, the pieces that each conducts are called, respectively, "the white pieces" and "the black pieces". The pieces are often not literally white and black, but some other colors (usually a light color and a dark color, respectively). The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise referred to as "white squares" or "light squares" on the one hand, and "black squares" or "dark squares" on the other. In most cases, the squares are not actually white and black, but a light color and a contrasting dark color. For example, the squares on plastic boards are often off-white ("buff") and green, while those on wood boards are often light brown and dark brown.

In old chess writings, the sides are often called Red and Black, because those were the two colors of ink then commonly available when hand-drawing or printing chess position diagrams.
