The scanning tunneling microscope is a device for viewing surfaces at the atomic level. It uses the quantum tunneling phenomenon, which allows particles to pass through a barrier that would normally be insurmountable. Electrons tunnel through the vacuum between two planar metal electrodes, on each of which is an adsorbed atom, providing a tunneling-current density that can be measured. Scanning one atom (taken as the tip) as it moves past the other (the sample) permits plotting of tip displacement versus lateral separation for a constant current. The calculation shows the extent to which scanning-tunneling-microscope images of an individual atom are visible. It confirms that for low bias, the microscope images the space-averaged dimensions of the electron orbitals across closely packed energy levels—the Fermi level local density of states.An atom can be ionized by removing one of its electrons. The electric charge causes the trajectory of an atom to bend when it passes through a magnetic field. The radius by which the trajectory of a moving ion is turned by the magnetic field is determined by the mass of the atom. The mass spectrometer uses this principle to measure the mass-to-charge ratio of ions. If a sample contains multiple isotopes, the mass spectrometer can determine the proportion of each isotope in the sample by measuring the intensity of the different beams of ions. Techniques to vaporize atoms include inductively coupled plasma atomic emission spectroscopy and inductively coupled plasma mass spectrometry, both of which use a plasma to vaporize samples for analysis.A more area-selective method is electron energy loss spectroscopy, which measures the energy loss of an electron beam within a transmission electron microscope when it interacts with a portion of a sample. The atom-probe tomograph has sub-nanometer resolution in 3-D and can chemically identify individual atoms using time-of-flight mass spectrometry.Spectra of excited states can be used to analyze the atomic composition of distant stars. Specific light wavelengths contained in the observed light from stars can be separated out and related to the quantized transitions in free gas atoms. These colors can be replicated using a gas-discharge lamp containing the same element. Helium was discovered in this way in the spectrum of the Sun 23 years before it was found on Earth.

Question: What is the name of the phenomenon that allows the particles to pass through?
Answer: quantum tunneling phenomenon

Question: At what level is a scanning tunneling microscope used at?
Answer: atomic
Though the word atom originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles. The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.

Question: What was initially known to be the smallest particle?
Answer: atom

Infinitesimal calculus was developed independently in the late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz. Today, calculus has widespread uses in science, engineering, and economics.In mathematics education, calculus denotes courses of elementary mathematical analysis, which are mainly  devoted to the study of functions and limits. The word calculus (plural calculi) is a  Latin word, meaning originally "small pebble" (this meaning is kept in medicine, see Calculus (medicine)). Because such pebbles were used for calculation, the meaning of the word has evolved for meaning method of computation. It is therefore used for naming specific methods of calculation and related theories, such as propositional calculus, Ricci calculus, calculus of variations, lambda calculus, and process calculus.

Question: Who developed infinitesimal calculus and when?
Answer: late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz
Although argon is a noble gas, it can form some compounds under various extreme conditions. Argon fluorohydride (HArF), a compound of argon with fluorine and hydrogen that is stable below 17 K (−256.1 °C; −429.1 °F), has been demonstrated.  Although the neutral ground-state chemical compounds of argon are presently limited to HArF, argon can form clathrates with water when atoms of argon are trapped in a lattice of water molecules. Ions, such as ArH+, and excited-state complexes, such as ArF, have been demonstrated. Theoretical calculation predicts several more argon compounds that should be stable but have not yet been synthesized.

Question: What noble gas is mentioned in these theoretical compounds?
Answer: argon
Argon is used for thermal insulation in energy-efficient windows. Argon is also used in technical scuba diving to inflate a dry suit because it is inert and has low thermal conductivity.Argon is used as a propellant in the development of the Variable Specific Impulse Magnetoplasma Rocket (VASIMR).  Compressed argon gas is allowed to expand, to cool the seeker heads of some versions of the AIM-9 Sidewinder missile and other missiles that use cooled thermal seeker heads. The gas is stored at high pressure.Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating. Also, potassium–argon dating and related argon-argon dating is used to date sedimentary, metamorphic, and igneous rocks.Argon has been used by athletes as a doping agent to simulate hypoxic conditions.  In 2014, the World Anti-Doping Agency (WADA) added argon and xenon to the list of prohibited substances and methods, although at this time there is no reliable test for abuse.

Question: What is the half-life of Argon 39?
Answer: 269 years
At the same time, however, two separate ship reports indicated that John had sustained winds of at least 55 knots (100 km/h, 65 mph), far stronger than the advisory strength of 35 knots (65 km/h, 40 mph). John would go on to restrengthen into a strong Category 1 hurricane after reentering the Central North Pacific, defying all JTWC predictions. After later reanalysis, the JTWC raised the estimated wind speeds of John for every advisory from 1200 UTC September 1 to its final advisory exactly a week later by at least 5 knots (9 km/h, 6 mph) and as much as 25 knots (46 km/h, 29 mph).

Question: How many miles per hour is 55 knots?
Answer: 65 mph
Clearing Johnston Atoll, John turned to the northwest and began strengthening again as shear decreased. On August 27 local time, John reached a secondary peak strength of 135 miles per hour (210 km/h), and shortly thereafter it crossed the International Date Line at approximately 22° N and came under the surveillance of the Guam branch of the Joint Typhoon Warning Center (JTWC). By crossing into the western Pacific, John also became a typhoon and was referred to as Typhoon John during its time in the western Pacific. Immediately after crossing the Date Line, John again weakened and its forward motion stalled. By September 1, John had weakened to a tropical storm and was nearly motionless just west of the Date Line. There, John lingered for six days while performing a multi-day counterclockwise loop. On September 7, a trough moved into the area and quickly moved John to the northeast. John crossed the Date Line again on September 8 and reentered the central Pacific.After reentering the central Pacific, John briefly reached a tertiary peak strength of 90 miles per hour (145 km/h), a strong Category 1 hurricane, well to the north of Midway Island. However, the trough was rapidly pulling apart John's structure, and the cold waters of the northern central Pacific were not conducive to a tropical cyclone. On September 10, the 120th advisory was released on the system, finally declaring John to have become extratropical approximately 1,000 miles (1600 km) south of Unalaska Island.

Question: Where did John become a typhoon?
Answer: western Pacific
During John's time in the Western North Pacific, the Joint Typhoon Warning Center (JTWC) had particular difficulty in forecasting and even estimating the strength of John. John weakened considerably after entering the Western North Pacific, and, before estimates were later revised, four consecutive advisories were issued that declared John a tropical depression. Each of these advisories called for imminent dissipation. As John persisted and did not dissipate as the JTWC had predicted, it was upgraded to a minimal tropical storm in the next advisory.

Question: Where was John while it was evaluated by the JWTC?
Answer: Western North Pacific
John affected both the Hawaiian Islands and Johnston Atoll, but only lightly. While John passed over 345 miles (550 km) to the south of Hawaiʻi, the islands did experience strengthened trade winds and rough surf along the southeast- and south-facing shores, and, while moving westward, on west-facing shores as well. The waves, ranging from 6 to 10 ft (1.8 to 3.0 m) in height, flooded beach parks in Kailua-Kona. Additionally, heavy rains on the Big Island of Hawaiʻi caused minor, localized flooding and some short-term road closures. No deaths, injuries or significant damages were reported in Hawaiʻi.Although John passed within 25 km (16 mi) of Johnston Atoll, it had weakened greatly to a Category 1 system by closest approach. Prior to the storm's arrival, waves between 20 and 30 ft (6.1 and 9.1 m) were reported on the island. Additionally, in the Northern Hemisphere, the strongest winds and heaviest rain lie to the north of a tropical cyclone, so the atoll, which lay to the south of the storm's path, was spared the brunt of the storm. Nonetheless, the 1,100-man personnel for the United States military base on Johnston Atoll had been evacuated to Honolulu as a precaution while John approached. Damage to structures was considerable, but the size of the island and relative functionality of the base led to low damage; monetary losses were estimated at close to $15 million (1994 US$).The remnants of John moved through the Aleutian Islands, producing a wind gust of 46 mph (74 km/h) in Unalaska. The storm brought a plume of warm air, and two stations recorded a high temperature of 66 °F (19 °C).

Question: How long did John pass south?
Answer: 345 miles

Question: Where were heavy rains?
Answer: Big Island of Hawaiʻi
The eccentricity of Pan's orbit causes its distance from Saturn to vary by ~4 km.  Its inclination, which would cause it to move up and down, is not distinguishable from zero with present data.  The Encke Gap, within which Pan orbits, is about 325 km wide.

Question: What feature of Pan's orbit causes a distance variation?
Answer: Encke Gap
The existence of a moon in the Encke Gap was first predicted by Jeffrey N. Cuzzi and Jeffrey D. Scargle in 1985, based on wavy edges of the gap which indicated a gravitational disturbance. In 1986 Showalter et al. inferred its orbit and mass by modeling its gravitational wake. They arrived at a very precise prediction of 133,603 ± 10 km for the semi-major axis and a mass of 5–10×10−12 Saturn masses, and inferred that there was only a single moon within the Encke gap. The actual semi-major axis differs by 19 km and the actual mass is 8.6×10−12 of Saturn's.

Question: How much does the semi-axis differ by?
Answer: 19 km
The moon was later found within 1° of the predicted position. The search was undertaken by considering all Voyager 2 images and using a computer calculation to predict whether the moon would be visible under sufficiently favorable conditions in each one. Every qualifying Voyager 2 image with resolution better than ~50 km/pixel shows Pan clearly. In all, it appears in eleven Voyager 2 images.

Question: How close was the moon to the exact position that it was thought to be in?
Answer: 1°
Allen was born Allan Stewart Konigsberg in the Brooklyn borough of New York City. He and his sister, Letty (b. 1943), were raised in Midwood, Brooklyn. He is the son of Nettie (née Cherry; November 8, 1906 – January 27, 2002), a bookkeeper at her family's delicatessen, and Martin Konigsberg (December 25, 1900 – January 8, 2001), a jewelry engraver and waiter. His family was Jewish, and his grandparents immigrated to the US from Russia and Austria and spoke Yiddish, Hebrew, and German. Both of Allen's parents were born and raised on the Lower East Side of Manhattan.His childhood was not particularly happy; his parents did not get along, and he had a rocky relationship with his stern, temperamental mother. Allen spoke German quite a bit in his early years. He would later joke that when he was young he was often sent to inter-faith summer camps. While attending Hebrew school for eight years, he went to Public School 99 (now the Isaac Asimov School for Science and Literature) and to Midwood High School, where he graduated in 1953. Unlike his comic persona, he was more interested in baseball than school and his strong arms ensured he was first to be picked for a team. He impressed students with his extraordinary talent with cards and magic tricks.For pay, he wrote jokes (or "gags") for agent David O. Alber, who sold them to newspaper columnists. At age 17 he legally changed his name to Heywood Allen and later began to call himself Woody Allen. According to Allen, his first published joke read: "Woody Allen says he ate at a restaurant that had O.P.S. prices—over people's salaries." He was earning more than both his parents combined. After high school, he attended New York University, studying communication and film in 1953, before dropping out after failing the course "Motion Picture Production". He studied film at City College of New York in 1954 but left before the end of the first semester. He taught himself rather than studying in the classroom. He taught at The New School and studied with writing teacher Lajos Egri.p.74

Question: Which parent of his lived longer?
Answer: Martin Konigsberg

Question: How old was Woody Allen when he took his name?
Answer: age 17

From 2003 through 2005 Novell released many products across its portfolio, with the intention of arresting falling market share and to move away from dependencies on other Novell products, but the launches were not as successful as Novell had hoped. In late 2004, Chris Stone again left the company, after an apparent control issue with then CEO Jack Messman. In an effort to cut costs, Novell announced a round of layoffs in late 2005. While revenue from its Linux business continued to grow, the growth was not fast enough to offset the decrease in revenue of NetWare. While the company's revenue was not falling rapidly, it wasn't growing, either. Lack of clear direction or effective management meant that Novell took longer than expected to complete its restructuring.

Question: When did Novell fire people to cut costs?
Answer: late 2005

Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European colonies and the arrival of enslaved Africans (c. late 16th–early 17th centuries), and are known only through archaeological investigations and oral history. Other civilizations were contemporary with the colonial period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own written records. Because many Christian Europeans of the time viewed such texts as pagan, men like Diego de Landa burned them, even while seeking to preserve native histories. Only a few hidden documents have survived in their original languages, while others were transcribed or dictated into Spanish, giving modern historians glimpses of ancient culture and knowledge.

Question: How were the records documented?
Answer: written
