Microphone

The condenser microphone, invented at Western Electric in 1916 by E. C. Wente,[19] is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers. Here, the diaphragm acts as one plate of a capacitor, and the vibrations produce changes in the distance between the plates. There are two types, depending on the method of extracting the audio signal from the transducer: DC-biased microphones, and radio frequency (RF) or high frequency (HF) condenser microphones. With a DC-biased microphone, the plates are biased with a fixed charge (Q). The voltage maintained across the capacitor plates changes with the vibrations in the air, according to the capacitance equation (C = ​Q⁄V), where Q = charge in coulombs, C = capacitance in farads and V = potential difference in volts.  The capacitance of the plates is inversely proportional to the distance between them for a parallel-plate capacitor. The assembly of fixed and movable plates is called an "element" or "capsule".

Lee de Forest

Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor, self-described "Father of Radio", and a pioneer in the development of sound-on-film recording used for motion pictures. He had over 180 patents, but also a tumultuous career—he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. His most famous invention, in 1906, was the three-element "Audion" (triode) vacuum tube, the first practical amplification device.  Although De Forest had only a limited understanding of how it worked, it was the foundation of the field of electronics, making possible radio broadcasting, long distance telephone lines, and talking motion pictures, among countless other applications.

Portrayal of women in American comics

The first known female superhero is writer-artist Fletcher Hanks's minor character Fantomah,[7] an ageless, ancient Egyptian woman in the modern day who could transform into a skull-faced creature with superpowers to fight evil; she debuted in Fiction House's Jungle Comics #2 (Feb. 1940), credited to the pseudonymous "Barclay Flagg". The first widely recognizable female superhero is Wonder Woman, from All-American Publications, one of three companies that would merge to form DC Comics. In an October 25, 1940, interview conducted by former student Olive Byrne (under the pseudonym 'Olive Richard') and published in Family Circle, titled "Don't Laugh at the Comics", William Moulton Marston described what he saw as the great educational potential of comic books (a follow up article was published two years later in 1942.[8]) This article caught the attention of comics publisher Max Gaines, who hired Marston as an educational consultant for National Periodicals and All-American Publications, two of the companies that would merge to form the future DC Comics. At that time, Marston decided to develop a new superhero. In the early 1940s the DC line was dominated by superpowered male characters such as the Green Lantern, Batman, and its flagship character, Superman. According to the Fall 2001 issue of the Boston University alumni magazine, it was his wife Elizabeth Hollowy's idea to create a female superhero.[9]  Marston introduced the idea to Max Gaines, cofounder (along with Jack Liebowitz) of All-American Publications. Given the go-ahead, Marston developed Wonder Woman with Elizabeth (whom Marston believed to be a model of that era's unconventional, liberated woman).[9] In creating Wonder Woman, Marston was also inspired by Olive Byrne, who lived with the couple in a polygamous/polyamorous relationship.[10] In a 1943 issue of The American Scholar, Marston wrote:

Fort Glanville Conservation Park

Construction of the fort began in 1878. It was officially opened in October 1880 and completed by 1882. Due to changes in the Port River and shipping movements, Fort Largs surpassed it for strategic importance by 1890. By the close of the 19th century, the fort was largely unused and had no defence significance. It was briefly used for military purposes during World War I and World War II, though not for its original defensive role. For much of the 20th century the area was put to a variety of uses including accommodation, a caravan park and a boy scout campsite. After coming into state government hands in 1951 it was declared as a conservation park and is now managed by the Department of Environment, Water and Natural Resources (DEWNR); preserving and showcasing its historic value. The fort and surrounds occupy the northern half of the 5-hectare (12-acre) conservation park, the southern half is a caravan park. The fort is a lunette shaped defensible battery that was supported by land forces for self-defence. When constructed it was seen as state of the art, incorporating powerful and modern weapons. Its main armament is two rifled muzzle-loading (RML) 10inch 20 ton guns backed up by two RML 64 pounder 64 cwt guns, both rare in their particular configuration. The fort retains its original 19th century cannons and three have been restored to working condition.

Basketball court

Basketball courts come in different sizes. In the National Basketball Association (NBA), the court is 94 by 50 feet (28.7 by 15.2m). Under International Basketball Federation (FIBA) rules,[1] the court is slightly smaller, measuring exactly 28 by 15 meters (91.9 by 49.2ft). In amateur basketball, court sizes vary widely. The baskets are always 10 feet (3.05m) above the floor (except possibly in youth competition). Basketball courts have a three-point arc at both baskets. A basket made from behind this arc is worth three points; a basket made from within this line, or with a player's foot touching the line, is worth 2 points. The free-throw line, where one stands while taking a foul shot, is located within the three-point arc at 15 feet from the basket. A foul shot is worth 1 point, but if a shot is made from the foul line while in play it is still worth 2 points.[2]

Question: How long is a standard basketball court?

General speed limits in Germany are set by the federal government. All limits are multiples of 5km/h. There are two default speed limits: 50km/h (31mph) inside built-up areas and  100km/h (62mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130km/h (81mph) based on accident experience, congestion and other factors, many rural sections have no general speed limit.

Generic drug

A generic drug is a pharmaceutical drug that has the same chemical substance as the drug that was originally developed, patented and innovated. Generic drugs are allowed for sale after the expiry of the patent of the original drugs. Because the active chemical substance is the same, the medical profile of generics is believed to be equivalent in performance.[1][2] The generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in characteristics such as manufacturing process, formulation, excipients, color, taste, and packaging.[2][3]

Question: What's the difference between generic medication and name brand?
