The International 420 Class Dinghy (not to be confused with the Club 420) is a double-handed (2 crew) monohull planing dinghy with centreboard, bermuda rig and center sheeting. The name describes the overall length of the boat in centimeters (the boat is exactly 4.2 meters long). The hull is fiberglass with internal buoyancy tanks. The 420 is equipped with spinnaker and optional trapeze, making teamwork necessary to sail it well. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed.The 420 was designed specifically to be easier to handle than its larger higher-performance cousin, the 470. The 420 was designed by French engineer Christian Maury, as a stepping-stone for club and youth sailing to the 470. The 420 is an International class recognized by the International Sailing Federation.A derivative of the 420 called the Club 420 is popular in the North America. This class is not recognised by International Sailing Federation or the International 420 Class Association and cannot be used at class events. The boats are very similar in appearance but the Club 420 is slightly stronger, heavier and less refined.

42355 Typhon (/ˈtaɪfɒn/; from Greek: Τυφών) is a scattered disc object that was discovered on February 5, 2002, by the NEAT program. It measures 162±7 km in diameter, and is named after Typhon, a monster in Greek mythology.A large moon was identified in 2006. It is named Echidna—formal designation (42355) Typhon I Echidna, /ᵻˈkɪdnə/, from Greek: Έχιδνα—after Echidna, the monstrous mate of Typhon. It orbits Typhon at ~1300 km, completing one orbit in about 11 days. Its diameter is estimated to be 89±6 km. Typhon is the first known binary centaur, using an extended definition of a centaur as an object on a non-resonant (unstable) orbit with the perihelion inside the orbit of Neptune.

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking).While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel.Examples of applications for 4130, 4140 and 4145 include structural tubing, bicycle frames, tubes for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages. 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by the United States military. These steels are also used in aircraft parts and therefore 41xx grade structural tubing is sometimes referred to as "aircraft tubing".

420356 Praamzius is a trans-Neptunian object (TNO) and possibly a dwarf planet in the Kuiper belt. It has the second-lowest eccentricity of any TNO, after 2003 YN179. Praamzius orbits near the 3:5 resonance with Neptune, but it takes about 160 Neptune orbits (26,500 years) to make an orbit less than would be expected of an object in a true 3:5 resonance. It was discovered on 23 January 2012, with precovery observations accepted by the Minor Planet Center dating back to December 2011, with possible precovery observations dating back to 2004 that have yet to be accepted. It was officially named on 22 February 2016 after the Lithuanian god of the sky, peace, and friendship.Praamzius is one of the most recently discovered minor planets that have been given a numeric designation, most likely because of the large number of observations, on average about one every 10 days, since it was discovered. All of the observations, except 6 in February 2013, were made by the Mount Graham Observatory, the discovery site.Analysis of precovery observations of Praamzius from 2002, 2003, 2004, and 2007, show that it is probably one of the reddest objects in the solar system, being more than 1.5 magnitudes fainter measured in the G (green) filter than the R (red) filter.

The 422nd Rifle Division was formed for the first time as a standard Red Army rifle division late in 1941, after the Soviet winter counteroffensive had begun, but was soon re-designated. A second formation began in March, 1942, again in the far east of Siberia, until July, after which it was moved west to join the reserves of Stalingrad Front in August. It was the highest-numbered rifle division to see active service in the front lines during the Great Patriotic War. Over the course of the next six months, the division distinguished itself in both defensive and offensive fighting and earned its re-designation as the 81st Guards Rifle Division on the first day of March, 1943. The 422nd was never reformed.

421-a tax abatement is a property tax abatement in the state of New York that is given to real estate developers for building new multi-family residential housing buildings. The program gets its name from being from section 421-a in the New York Real Property Tax Law. The 421-a program began in 1971, and has since included provisions in it to mandate the creation of affordable housing units in order to qualify for the program. Under the original program, areas in which developers qualified for the tax break included all of Manhattan and portions of the rest of New York City. The original program lapsed in January 2016 after disagreements between the state government and the New York City government, but a deal was made in November 2016 between unions, developers, and Governor Andrew Cuomo to bring it back, pending the approval of the New York State Legislature. In the April 2017 budget negotiations, the program was officially renewed, with the official new program name being "Affordable New York". The program is administered by the New York City Department of Housing Preservation and Development (HPD). Under the program, the city government stands to lose billions of dollars in foregone property tax revenue, making this program controversial.

== Events ===== 429 BC ======= By place ========== Greece ======The Athenians under Xenophon march into Thrace to attack Chalcis. They destroy crops outside Spartolus and begin negotiating with pro-Athenian factions in Chalcis, but the anti-Athenian factions ask for help from Olynthus. An army from Chalcis, Spartolus, and Olynthus meet the Athenians in battle, but their hoplites are defeated. Reinforcements soon arrive from Olynthus, and they launch a second attack on the Athenians. The Athenians are routed, with all of their generals and 430 other men killed.The Athenian admiral Phormio has two naval victories, the Naupactus and the Battle of Chalcis at the mouth of the Corinthian Gulf. In the first battle, his 20 ships defeat 47 Corinthian ships commanded by Machaon, Isocrates, and Agatharchidas that were advancing to reinforce the Spartan general, Cnemus' campaign in Acarnania. In the second battle, Phormio routs Cnemus' 77-vessel fleet.The Athenians, in alliance with Polychna, destroy the Cretan city of Kydonia.The Macedonian king, Perdiccas II, once again betrays the Athenians and sends 1000 troops to support a Spartan assault on Acarnania but they arrive too late to help. In response to this, King Sitalkes of Thrace invades Macedonia with a vast army that includes independent Thracian tribes (such as the Dii) and Paionian tribes (Agrianes and Laeaeans). His progress is slowed when the promised support from Athens fails to materialise. So Perdiccas once again uses diplomacy to ensure the survival of Macedonia. He promises the hand of his sister in marriage to the nephew of Sitalkes, who then persuades Sitalkes to leave Macedonia.The plague in Athens that is killing thousands of the city's inhabitants, claims Pericles. Cleon, who has headed the opposition to Pericles' rule, succeeds to power in Athens following Pericles' death.=== 428 BC ===Hippolytus was first performed for City Dionysia and was written by Euripedes==== By place ========== Greece ======The chief city of Lesbos, Mytilene, revolts against Athenian rule. The Spartan admiral, Alcidas, leads 40 Peloponnesian alliance ships with the aim of assisting the inhabitants of Mytilene. However, the rebellion by Mytilene is crushed before his forces can arrive.Despite encouragement from the Ionian leaders to engage the Athenians, Alcidas declines. Rather, Alcidas leads his fleet to Cyllene where the Spartans resolve to strengthen the fleet and send it to Corcyra where a revolution has broken out. Spartan leaders, Brasidas and Alcidas, then defeat a fleet of Corcyran ships. However, they retire when word reaches them that 60 Athenian ships from Leucas under the command of Eurymedon have been dispatched to intercept them.====== Italy ======The Greek colony of Cumae in Italy falls to the Samnites, who begin to take control of the Campanian plain.==== By topic ========== Literature ======Euripides' play Hippolytus is performed in the Dionysia competition, the famous Athenian dramatic festival. The play is awarded first prize.Sophocles writes Oedipus Rex.=== 427 BC ======= By place ========== Greece ======Sparta's King Archidamus II is succeeded by his son Agis II.Following the surrender of Mytilene to Athens, the Athenian leader Cleon insists that the city be destroyed. In response to the pleadings of a number of Athenian citizens, Cleon's decree to destroy the population of Mytilene is reversed with only the ringleaders of the Mytilenean revolt being executed.Plataea surrenders to the Spartans and Thebans after its garrison comes close to death from starvation. Over 200 prisoners are put to death and Plataea is destroyed.The civil war in Corcyra, in which the Athenians and the Spartans have interfered ineffectually, results in a victory of the democrats (who support an alliance with Athens) over the oligarchs.In an effort to blockade Sparta from access to Sicilian corn, Athens responds to a plea for help from a delegation from the city of Leontini led by Gorgias, the sophist and rhetorician. Leontini is being threatened by Syracuse which is allied to Sparta. However, the Athenian mission led by the Athenian general Laches is unable to offer much help. Laches is later prosecuted by Cleon for his unsuccessful mission to support Athenian interests in Sicily.====== Roman Republic ======The Quaestorship is opened to the Plebs.=== 426 BC ======= By place ========== Greece ======The Athenian leader Cleon and Athenian general Demosthenes revitalise the city's military and naval forces despite opposition from Nicias, a rich merchant and soldier, and his supporters.Demosthenes unsuccessfully besieges the Corinthian colony of Leukas. As a result, he does not return to Athens, fearing for his life. However when, later in the year, Ambracia invades Acarnania, and the Acarnanians seek help from Demosthenes, who is patrolling the Ionian Sea coast with twenty Athenian ships, he reaches the Athenian naval base in the Gulf of Corinth at Naupactus and secures it just in time to defend it against a large Spartan army from Delphi under Eurylochus which has come to assist the Ambraciots. Demosthenes defeats the Spartan army and Eurylochus is killed during the Battle of Olpae. The Acarnanians and Ambraciots then sign a peace treaty.An Athenian army under Nicias, Hipponicus and Eurymedon defeats a combined Tanagran and Theban army in the Battle of Tanagra.=== 425 BC ======= By place ========== Persian Empire ======Artaxerxes I, Achaemenid king of Persia, is succeeded by his son Xerxes II.====== Greece ======Demosthenes captures and fortifies the port of Pylos in the Peloponnesus, giving Athens a strong base close to Sparta. Meanwhile, a Spartan army, commanded by Brasidas, lands on the nearby island of Sphacteria, but is repulsed by the Athenians. An Athenian fleet summoned by Demosthenes bottles up the Spartan navy in Navarino Bay.Cleon joins Demosthenes in the invasion by Athenian troops of Sphacteria. The resulting Battle of Pylos results in an Athenian victory leading to the surrender of many of the Spartan troops. Pylos remains in Athenian hands, and is used as a base for raids into Spartan territory and as a refuge for fleeing Spartan helots.Following the failure of peace negotiations between Athens and Sparta, a number of Spartans stranded on the island of Sphacteria after the Battle of Pylos are attacked by an Athenian force under Cleon and Demosthenes. The resulting Battle of Sphacteria leads to a further victory by the Athenians over the Spartans. The Spartans sue for peace, but the Athenian leader Cleon persuades Athens to refuse.====== China ======Zhou wei lie wang becomes King of the Zhou Dynasty of China.==== By topic ========== Architecture ======Callicrates starts to build the Temple of Athena Nike on the Acropolis in Athens (approximate date). Between -410 and 407 BC the temple is surrounded by a parapet.====== Art ======What some historians call the Rich style begins in Greece.====== Literature ======Euripides' play Hecuba is performed.Aristophanes' play The Acharnians is performed. Produced by Callistratus, it wins Aristophanes a first prize at the Lenaea.=== 424 BC ======= By place ========== Persian empire ======Xerxes II rules as King of Persia for only about 45 days until he is killed. He is reportedly murdered, while drunk, by Pharnacyas and Menostanes on the orders of Secydianus (or Sogdianus), the son of one of Artaxerxes I's concubines, Alogyne of Babylon.====== Greece ======At the Congress of Gela, the statesman Hermocrates of Syracuse persuades the cities of Sicily to agree to make peace and urges the exclusion of foreign powers. As a result, the three-year war between his city and Sicily's pro-Athenian towns ends and the Athenian forces, which had been sent to Sicily to support Greek settlements, are forced to withdraw.Demosthenes and Hippocrates attempt to capture Megara, but they are defeated by the Spartans under their general Brasidas. Demosthenes then marches to Naupactus to assist in a democratic revolution, and to gather troops for an invasion of Boeotia. However, Demosthenes and Hippocrates are unable to coordinate their attacks and Hippocrates is defeated at the Battle of Delium by Pagondas of Thebes. During the battle, Socrates is said to have saved the life of Alcibiades. Demosthenes attacks Sicyon and is defeated as well.After he frustrates the Athenian attack on Megara, Brasidas marches through Boeotia and Thessaly to Chalcidice at the head of 700 helots and 1000 Peloponnesian mercenaries to join the Macedonian king Perdiccas II. Refusing to be made a tool for the furtherance of Perdiccas' ambitions, Brasidas wins over the important cities of Acanthus, Stagirus, Amphipolis and Torone as well as a number of minor towns. An attack on Eion is foiled by the arrival of Thucydides at the head of an Athenian squadron.Brasidas' capture of the city of Amphipolis is a major reverse for Athens, for which the Athenian general (and future historian) Thucydides is held responsible and banished. This gives Thucydides the opportunity for undistracted study for his History and for travel and wider contacts, especially on the Peloponnesian side (Sparta and its allies).Nicias captures the Peloponnesian island of Cythera, from which to harry the Spartans.==== By topic ========== Literature ======Sophocles' play Oedipus Rex is performed.====== Architecture ======The temple to Athena Nike (also known as the Wingless Victory) on the Athenian Acropolis is completed.

Seventeen representatives from each side swear an oath to uphold the treaty, which is meant to last for thirty years or one generation (meaning they are not responsible for the next generation's decision). All of Sparta's allies agree to sign the peace, except for the Boeotians, Corinth, Elis, and Megara.Alcibiades engineers an anti-Spartan alliance between Athens and the democracies of Argos, Mantinea and Elis.====== Italy ======The city of Cumae, the most northerly of the Greek colonies in Italy, falls to the Samnites.==== By topic ========== Art ======The construction of the Porch of the Maidens (the Caryatid Porch) commences at the Erechtheion which is part of the Acropolis in Athens.====== Drama ======Aristophanes' play The Peace is performed.=== 420 BC ======= By place ========== Greece ======The young and popular Alcibiades is elected "Strategos" (one of a board of ten generals) and begins to dominate Athenian life and politics.
