In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays are also known as plane angles as they lie in the plane that contains the rays. Angles are also formed by the intersection of two planes; these are called dihedral angles. Two intersecting curves may also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection.

The magnitude of an angle is called an angular measure or simply "angle". Angle of rotation is a measure conventionally defined as the ratio of a circular arc length to its radius, and may be a negative number. In the case of a geometric angle, the arc is centered at the vertex and delimited by the sides. In the case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation.

E, or e, is the fifth letter and the second vowel letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is e (pronounced ); plural es, Es, or E's.

It is the most commonly used letter in many languages, including Czech, Danish, Dutch, English, French, German, Hungarian, Latin, Latvian, Norwegian, Spanish, and Swedish.

G, or g, is the seventh letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages, and others worldwide. Its name in English is gee (pronounced ), plural gees.

The lowercase version can be written in two forms: the single-storey (sometimes "opentail") and the double-storey (sometimes "looptail") . The former is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis. Lenses are made from materials such as glass or plastic and are ground, polished, or molded to the required shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called "lenses", such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses.

Lenses are used in various imaging devices such as telescopes, binoculars, and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia.

Mount is often used as part of the name of specific mountains, e.g. Mount Everest.

Mount or Mounts may also refer to:

Sony Group Corporation (ソニーグループ株式会社, Sonī, , SOH-nee), formerly known as Tokyo Tsushin Kogyo K.K. (東京通信工業株式会社, Tokyo Telecommunications Engineering Corporation) and Sony Corporation (ソニー株式会社), commonly known as Sony, is a Japanese multinational conglomerate headquartered in Minato, Tokyo, Japan. The Sony Group comprises entities such as Sony Corporation, Sony Semiconductor Solutions, Sony Entertainment (including Sony Pictures and Sony Music Group), Sony Interactive Entertainment, Sony Financial Group, and others.

Sony was established in 1946 as Tokyo Tsushin Kogyo by Masaru Ibuka and Akio Morita. This electronics company, known for creating products such as the transistor radio TR-55, the home video tape recorder CV-2000, the portable audio player Walkman, and the compact disc player CDP-101, embarked on diverse business ventures. In 1988, Sony acquired CBS Records, and in 1989, it acquired Columbia Pictures. The company also introduced the home video game console PlayStation in 1994, which was the first of the eponymous brand. In Japan, Sony expanded into the financial sector. In 2021, Sony transformed into a holding company, handing over the name Sony Corporation to its subsidiary as the electronics company.

Sony, with its 55 percent market share in the image sensor market, is the largest manufacturer of image sensors, the second largest camera manufacturer, and is among the semiconductor sales leaders. It is the world's largest player in the premium TV market for a television of at least 55 inches (140 centimeters) with a price higher than $2,500 as well as second largest TV brand by market share and, as of 2020, the third largest television manufacturer in the world by annual sales figures.

Although not being a part of any traditional keiretsu, Sony has a weak tie to the Sumitomo Mitsui Financial Group (SMFG), which traces its roots to the Mitsui zaibatsu. This connection dates back to the 1950s when it was the only bank the company dealt with. Sony is listed on the Tokyo Stock Exchange (in which it is a constituent of the Nikkei 225 and TOPIX Core30 indeces) with an additional listing in the form of American depositary receipts listed in the New York Stock Exchange (traded since 1961, making it one of the oldest Japanese company to be listed on an American exchange), and was ranked 88th on the 2021 Fortune Global 500 list. In 2023, the company was ranked 57th in the Forbes Global 2000.
