The shape and length of the apex can be different. It can even sometimes be different within the same writing. While pretty much all apices are made up of a line sloping up to the right, the line can be more or less curved, and is different in length from less than half the height of a letter to more than the height of a letter. Sometimes, it is put at the top with a hook, pointing out to the left. Rather than being centered over the vowel it changes, the apex is often drawn to the right.
Later, it developed into the acute accent, which is still used in some languages to mark vowel length. In particular, Czech and Slovak, Hungarian, Irish, and (a long time ago) Icelandic.
Although not really known by some modern Latinists, the sign was actually used a lot during classical and postclassical times. The reason why it is not usually noticed is probably because of its smallish size and the fact that it is usually quite thin. People who look carefully will soon start to notice apices in the exhibits of any museum, not only in many of the more formal epigraphic writings, but also in handwritten palaeographic things.
Forgetting the apex, modern Latin spelling has recently started marking long vowels by using the macron. The macron is a sign that had always been used, and still is, to mark metrically long "syllables" (more recently called "heavy" syllables). This has caused confusion between syllable and vowel length in Latin, and most western dictionaries still cannot describe the nature of Latin vowels properly because of this. To make even more confusion, the acute accent is sometimes used in Latin to mark stressed syllables, just like in Spanish, when the macron is not used.
The apex is often thought to be the opposite of another ancient Latin diacritic, the sicilicus, which is said to have been used above "consonants" to show that they should be pronounced as doubles. However, in his article "Apex and Sicilicus", Revilo P. Oliver says that they are the same sign, a "geminationis nota". This was used over any letter to show that the letter should be read twice.
If Revilo P. Oliver is right, the apex as a sign showing vowel length would have been made in the time when long vowels were written double. Then, when long vowels were not regularly written twice.
However, Oliver's view that the two marks were the same has recently been challenged.
Acute
Acute can mean:
Differential geometry
Differential geometry is a field of mathematics. It uses differential and integral calculus as well as linear algebra to study problems of geometry. The theory of the plane, as well as curves and surfaces in Euclidean space are the basis of this study. Big discoveries were made in the 18th and 19th century. In geometry, the sum of the angles of a triangle is 180 degrees. Carl Friedrich Gauß wondered whether triangle bearings of ships really has a sum of angles of exactly 180 degrees; with this question he was among the pioneers of modern differential geometry.
A long time ago, differential geometry was used for map projections. Today, it is used for fields as diverse as general relativity theory, or satellite navigation. Grigori Perelman's proof of the Poincaré conjecture uses differential geometry.
New Azerbaijan Party
The New Azerbaijan Party ("Yeni Azərbaycan Partiyası", YAP) is the ruling political party in Azerbaijan since 1993.
It was formed on 18 December 1992 by the former President of Azerbaijan Heydar Aliyev, who led it until his retirement and death in 2003. It is now led by his son, Ilham Aliyev, who succeeded his father as the party leader and as President of Azerbaijan since October 31, 2003. The founder of the party, Heydar Aliyev, was a member of the Communist Party of the Soviet Union until July 1991 before the collapse of the Soviet Union and the independence of Azerbaijan later that year. The headquarters of the party is in the capital city Baku.
The party's stated ideologies are lawfulness, secularism, and Azerbaijani nationalism. It wants to build a "social-oriented" economy, meaning a middle path between socialism and "laissez-faire" capitalism (a mixed economy), and lists civil solidarity and social justice as the basis of its ideology.
Tonga at the Olympics
Tonga has been in seven Olympic Summer Games. They have never been in the Winter Games.
Tonga was the smallest independent nation to win an Olympic medal. Super Heavyweight Boxer Paea Wolfgram won a silver medal in the 1996 Summer Olympics.
Tonga wanted to enter a delegation for the 2010 Winter Olympics. The Tonga Amateur Sports Association (TASA) said they had one athlete to compete in the luge event. In December 2008, two male athletes were selected to travel to Germany for training, but only one of them would be at the Olympics. Bruno Banani was selected as Tonga's candidate. He failed to qualify by crashing in the final round of qualifications.
Forgery
Forgery is producing a fake document, signature, banknote, or work of art in order to deceive. It is illegal, as it is fraud. Forging money and certain other items is called counterfeiting.
Crazyracing Kartrider
Crazyracing Kartrider () is an online computer racing game. Nexon opened a beta version of this game in 2004. There are various kinds of karts and items that you can use in this game.

In flag mode, players try to bring back a flag to your team zone.
It is easy to play. Only arrow keys and Ctrl, Alt keys are needed to control your kart. Decorating and changing your character and kart is another interesting part of this game. Lucci is game money. You can get it by racing. You need Lucci to buy a kart, or character accessories.
Recently Nexon launched Kartrider Rush to Apple App store. Kartrider Rush is minimized version of Crazyracing Kartrider.
Hanok
Hanok is a type of house. It is built in a traditional Korean style of architecture.
The main feature of Hanok is that it has combination of ondol, the Korean under-floor heating system, and wooden floor for heating and cooling. This style is mainly used in Korea because of problems caused by the area having both a continental climate and an oceanic climate.
Hanoks have different shapes in different parts of Korea. In the northern part of the Korean peninsula, Hanok have the structure of a house with several wings. The wings are often built in either a square or the letter L. This helps keep the wind out of the house in the colder northern places and helps keep the house warm. These kind of house also has low roofs. In the warmer southern Korean peninsula, Hanok have a single wing and a wooden floor. This helps let the air in and out.
The Hanok is also different based on the class of the people who live it. Hanok of Upper class people usually have tiled roofs (called "giwa") while lower class houses have roofs made of rice-straw (called "choga"). Hanok for the upper-class people are built not only to be homes, but also to be very ornamental.
A cappella
A cappella music is music where people sing without instruments.
In a choir, there are up to 5 parts: soprano, alto, tenor, baritone, and bass. A cappella can also have those 5 parts. A difference is with percussion. With musical instruments, percussion is done with musical instruments that you hit, such as drums. In an a cappella performance, a person makes the percussion sound. For a beatbox performance, performers make sounds like electric drums, synthesizer and electric guitar. Another part of percussion in a cappella performance is making classical drum sounds for tapping the beat.
The word a cappella is Italian for "in the manner of the church" or "in the manner of the chapel". It was first used in religious music. Gregorian chant is an example of a cappella singing.
