Postfix notation is a mathematical notation. It is a way to write down equations and other mathematical formulae. Postfix notation is also known as Reverse Polish Notation. The notation was invented by Charles Hamblin in 1920. He wanted to simplify writing logic equations. He used Jan Łukasiewicz's prefix notation. When postfix notation is used, no grouping elements (like parenthesis) are needed. Some computer languages, like Postscript use Postfix notation. It is also used in some models of Hewlett-Packard calculators With postfix notation, the operations are noted after their arguments. Because of this, postfix is relatively easy to do with computers that have a stack to do calculations. Further Explanation. Reverse Polish Notation uses a system that involve "stacks", each of which stores a certain value in specific ranks. The stacks usually start off with the first stack (often called the X stack), followed by the second stack (often called the Y stack), the third stack, and so on. New values can be entered on the first stack by pushing up the stack ranks by one. On a Reverse Polish Notation calculator, the "Enter" function would do the same.  Using a common operator (plus, minus, multiply, or divide) will make the operator act from the first stack to the second stack. For example, the Reverse Polish Notation "12 3 /" means "take the numbers 12 and 3, then divide 12 by 3". On a Reverse Polish Calculator, this is written as "12 Enter 3 /", to denote each declared ranking up of the stacks. Reverse Polish Notation is able to deal with expressions involving brackets too. Suppose there is a normal equation "4 * (5 + 8)". In Reverse Polish Notation, this expression will be formatted as "5 8 + 4 *". The "5 8 +" part refers to the bracket "5 + 8" to equal 13. The "4 *" part refers to multiplying the result together to get 52. On that step, the resulting stack from adding 5 and 8 is automatically raised one rank after adding in the new value 4. Then
Infix notation is the commonly used arithmetic and logical formula notation. The operators are written between the operands they act on (e.g. 2 + 2). It is not as simple to parse by computer as prefix notation ( e.g. + 2 2 ) or postfix notation ( e.g. 2 2 + ), but many programming languages use it due to its familiarity. In infix notation, parentheses are necessary to show the order of the operations. In prefix or postfix notation no parenthesis are needed. When there are no parentheses, there are rules that show the order of operations. The rules are explained in the order of operations article.
Fiqh or Islamic jurisprudence () is an expansion of Sharia law and is meant to be used with fatwas by Islamic clerics (known as 'Ulema' in Arabic) to help Muslims not break Sharia law. Fiqh is a section of Islamic law which deals with acts of Muslim, that includes both worship and daily life actions.  In Sunni Islam there are four main schools of thought, they are: The different schools of thought are not different beliefs but different views .

Hurricane Wilma was the most intense tropical cyclone ever recorded in terms of pressure in the Atlantic Ocean. It destroyed parts of the Yucatán Peninsula and southern Florida during October in the 2005 Atlantic hurricane season. Wilma broke several records for both strength and seasonal activity. Wilma was only the third Category 5 ever to develop in the month of October, and with its formation, the 2005 season became the most active hurricane season on record, exceeding a total of 21 storms from the 1933 season. Wilma was the twenty-second storm (including it was a subtropical storm as discovered in reanalysis), thirteenth hurricane, sixth major hurricane, and fourth Category 5 hurricane of the record-breaking Atlantic hurricane season. Meterological history. The meteorological history of Hurricane Wilma, the strongest tropical cyclone known in the Western Hemisphere, began in the second week of October 2005. A big weather system formed across much of the Caribbean Sea and slowly organized to the southeast of Jamaica. By late on October 15, the system had become strong enough for the National Hurricane Center to name it Tropical Depression Twenty-Four. The depression slowly moved southwestward, and in conditions that were good for strengthening, it strengthened into Tropical Storm Wilma on October 17. In the beginning, development was slow because of its large size, although thunderstorms slowly organized. From October 18, and over the next day, Wilma underwent explosive deepening over the open waters of the Caribbean; in a 30-hour period, the system's central atmospheric pressure dropped from 982 mbar (29.00 inHg) to the record-low value of 882 mbar (26.05 inHg), while the winds increased to 185 mph (300 km/h). At its strongest, the pinhole eye of Wilma was about 3 miles (5 km) in diameter, the smallest known eye in an Atlantic hurricane. After the inner eye died off because of an eyewall replacement cycle, Wilma weakened to Category 4 status, and on October 21, it made landfall on Cozumel and on the Mexican mainland with winds of about
The Yucatán Peninsula is a peninsula in North America. It separates the Caribbean Sea from the Gulf of Mexico. The peninsula is east of the Isthmus of Tehuantepec, a northwestern geographic divider, separating Central America from the rest of North America. Before the conquistadores came, the peninsula was the home of the Mayan civilization. The peninsula includes the Mexican states of Yucatán, Campeche, and Quintana Roo; the northern part of Belize; and Guatemala's northern department of El Petén. Mexican states on the isthmus to the south and west of the peninsula include Chiapas and Tabasco.  The Chicxulub crater is on the north coast.

A static mixer is a piece of equipment that is used to mix liquids in laboratories. It has a unique shape. Structure. A static mixer is made up of rectangular plates twisted around at 180° so that they make a double-helix shape. Liquids flow along the curves of the static mixer and also are separated by the smooth sides of the mixer. The mixer can also be turned clockwise, or right, and then quickly turned counter-clockwise, or left. This creates opposite currents in the liquid and mixes it more efficiently. Uses. The static mixer can be used to mix acids and alkalis for a neutralization. It can also be used to mix two liquids that normally wouldn't mix, like oil and water (see emulsion). It separates the particles of the water and oil until they become so small that they mix.
Komárno is a town in the southwest of Slovakia. It is an important, historical town which is famous for having a historical fortification. The river Váh flows into the Danube at Komárno. The Danube at this point forms the border between the countries Slovakia and Hungary. The Hungarian name for the town is Komárom. History. At first there was just one town, with the Danube flowing through the middle of the town. Since the end of World War I, when Czechoslovakia became a separate country from Hungary, the town has been split into two: Komárno is on the left (north) bank of the river, now in Slovakia, and Komárom is on the right (south) bank of the river, in Hungary. Komárno has a population of 37.000 and Komárom has a population of 19.600. The two towns are joined by a bridge. People have lived in the area of Komárno for thousands of years. The first castle was built in the 10th century. In 1244 a law was made which said that every merchant who sailed a boat down the Danube past Komárno had to stop for several days in Komárno and unload all the cargo so that people could buy it if they wanted. If the merchant did not want to do this he had to pay a large duty (amount of money) to continue his journey. This law was stopped in 1751.  In the 15th century Komárno had become very important. The rulers and the court of the kingdom of Hungary often stayed there. The fortress was very powerful and they managed to fight off Turkish invaders after the Turks had already captured Esztergom and Buda. The fort was badly damaged in 1783 in an earthquake, but it was built up again because of the Napoleonic wars. Today Komárno is a nice town to visit. There are many tourist attractions, especially the fort which is on the Hungarian side of the town (Komárom). There are also spa health centres where people can swim or bathe gently in the waters which help to make people who are ill healthy again.  Notable people. Famous people who were born in Komárno are:
Komarno (, , ) is a city in the Horodok Raion (district) of the Lviv Oblast (province) in western Ukraine. 4,000 people live there. It was founded in 1324.

The Hasidic dynasty of Komarno comes from this town.
In statistics and probability theory, correlation is how similar two sets of data are. This relationship means that if one set of data changes, the other will change as well (at least more commonly than if it were up to pure chance). Correlation does not always mean that one causes the other. In fact, it is very possible that there is a third factor involved. Correlation can have one of two directions: Positive or negative. If it is positive, then the two sets go up together. If it is negative, then one goes up while the other goes down. Lots of different measurements of correlation are used for different situations. For example, on a scatter graph, people draw a line of best fit to show the direction of the correlation. Correlation can be measured through correlation coefficients. The most common correlation coefficients are Pearson correlation coefficient and Spearman's rank correlation. Correlation is useful in real life. An example of correlation is the height of a parent and their children. Explaining correlation. "Strong" and "weak" are words used to describe the strength of correlation. If there is strong correlation, then the points are all close together. If there is weak correlation, then the points are all spread apart. There are ways of making numbers show how strong the correlation is. These measurements are called correlation coefficients. The best known is the Pearson product-moment correlation coefficient, sometimes denoted by formula_1 or its Greek equivalent formula_2. You put in data into a formula, and it gives you a number between -1 and 1. If the number is 1 or −1, then there is strong correlation. If the answer is 0, then there is no correlation. Another kind of correlation coefficient is Spearman's rank correlation coefficient. Correlation vs causation. Correlation does not always mean that one thing causes the other (causation or causal relationship), because there might be something else that is at play. For example, on hot days people buy ice cream, and people also go to the beach where some are attacked by sharks. There is a correlation between ice cream sales and shark attacks (they both go up as the temperature goes up in this case). But that ice cream sales
Sunscreen (also known as sunblock, or sun cream) is a photo-protective topical product that helps prevent skin damage from ultraviolet (UV) radiation emitted by the sun. It reduces sunburn and other skin damage, with the goal lowering your risk of skin cancer.  The most effective sunscreens protect against both UVB (ultraviolet radiation with wavelength between 290 and 320 nanometres), which can cause sunburn, and UVA (between 320 and 400 nanometres), which damages the skin with more long-term effects, such as premature skin aging. Most sunscreens work by containing either a petrochemical compound that absorbs ultraviolet light (such as oxybenzone) or minerals that reflects light (such as titanium dioxide, zinc oxide), or a combination of both. Sunscreen is regulated as an OTC product by the FDA. Most sunscreens are not considered reef safe as they use petrochemicals. As such the use of petrochemical based sunscreen has been banned in ecological and progressive area's, such as, Mexico's Marine Reserves, the State of Hawaii, Aruba, Thailand's National Park areas, the Marshal Islands.
