The "new" schools (Sakya, Kagyu, and Geluk) divide the teachings into only four levels. The first three are the same as in the Nyingma school. The last level is simply called Anuttarayogatantra ("Highest Yoga Tantra"). These Highest Yoga Tantras are divided into "mother", "father" and "non-dual" tantras. The new schools use a practice called Mahamudra in place of Dzogchen.

Alpha
Alpha (uppercase/lowercase Α α), is the first letter of the Greek alphabet, used to stand for the "a" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 1. Letters that came from it are the Roman A and Cyrillic А.
Alpha is often used in physics and chemistry as a symbol or in the names of things, for example alpha particles (which are two protons and two neutrons bound together into a particle the same as a helium nucleus). The symbol is also used a lot in mathematics in algebra, for example in naming angles, and in statistics, to represent statistical significance level.
Beta
Beta (uppercase/lowercase Β β), is a letter of the Greek alphabet, used to represent the "b" sound in Ancient Greek and "v" in Modern Greek. In the system of Greek numerals, it has a value of 2. Letters that came from it include the Roman B and Cyrillic Б.
The sounds [b] and [v] resemble each other a lot. In Ancient Greek the "b" sound became "v" around 200 BC. Therefore, the letter B means the "v" sound in the Cyrillic alphabet, and a new letter, Б, was made for [b].
The letter beta is also used in finance, science and mathematics. For example. the beta function is named after the capital letter Β, and the probability of type II error in statistics is written with the lowercase β.
Gamma
Gamma (uppercase/lowercase Γ γ), is the third letter of the Greek alphabet, used to represent the "g" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 3. Letters that came from it include the Roman C and Cyrillic Г.
In mathematics, the lowercase γ is used to represent Euler–Mascheroni constant, and the uppercase Γ is used to represent gamma function and gamma distribution.
In physics, gamma rays (γ-rays) are a kind of radiation that result from nuclear decay. In the physics and engineering, gamma is used to represent many different things, depending on the subject.
Epsilon
Epsilon (uppercase/lowercase Ε ε), is the letter of the Greek alphabet, used to represent the "e" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 5. Letters that came from it include the Roman E and Cyrillic Е. It is also used in calculus to represent a very small number (particularly in proofs involving limit). In set theory, a typographical variant of epsilon can be used to represent the statement "a is a member of set A" (symbolically formula_1).
Digamma
Digamma or Wau (uppercase/lowercase Ϝ ϝ ς) was an old letter of the Greek alphabet. It was used before the alphabet converted its classical standard form. It looked like a Latin "F", but it was pronounced like "w". In the 5th century BC, people stopped using it because they could no longer pronounce the sound "w" in Greek. However, they kept it as a sign for the number "6" in the system of Greek numerals. It was originally called "Wau" because of its sound. Later, when the sound was lost, it was called "Digamma", which means "double Gamma", because it looks like a Gamma (Γ) with two hooks. The Latin letter F was also taken over from Wau.
In mathematics, the name "digamma" is used in digamma function, which is the derivative of the logarithm of gamma function (that is, formula_1).
Stigma (letter)
Stigma (uppercase/lowercase Ϛ ϛ), is a sign that was used in the Greek alphabet for the combination of the two letters Sigma (σ) and Tau (τ). It is also used as a symbol for the number 6 in the system of Greek numerals.
Zeta
Zeta (uppercase/lowercase Ζ ζ), is the letter of the Greek alphabet, used to represent the "z" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 7. Letters that came from it include the Roman Z and Cyrillic З.
Eta
Eta (uppercase/lowercase Η η) is a letter of the Greek alphabet. In very early Greek writing it stood for the consonant sound "h", but in Classical Greek it stood for a long vowel "e". In Modern Greek, it is pronounced as "i". In the system of Greek numerals, it has a value of 8. Letters that came from it include the Roman H and Cyrillic И.
In mathematics, the lowercase η is used to represent Dirichlet eta function. The same letter is also used to represent conformal time in cosmology, efficiency in telecommunications and elasticity in economics.
Heta
Heta (uppercase/lowercase ) is another name for the letter Eta (Η), a letter of the Greek alphabet, and also for some other variant forms of it. This name is used to show that this letter at first was pronounced as "h", just like in Latin. Later, in the Ionian dialect of Greek, people stopped pronouncing the sound "h", and therefore they gave the letter a new meaning and used it for a long "e" sound instead. Some other dialects then took over this new letter "Eta", and so they had to find a new form for the letter for "h". In some dialects they invented a new letter "" to stand for "h". Today, the name "Heta" is also used for this letter.
Theta
Theta (uppercase Θ / lowercase θ), is a letter in the Greek alphabet. It represents the "th" sound (as in "think") in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 9. The Cyrillic letter Ѳ came from theta.
In mathematics, the lowercase θ is used as a variable to represent an angle, and the uppercase Θ is used in big-theta notation (a variant of big-O notation). The lowercase θ is also used to represent the potential temperature in meteorology.
Iota
Iota (uppercase/lowercase Ι ι), is the letter of the Greek alphabet, used to represent the "i" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 10. Letters that came from it include the Roman I and Cyrillic І.
In mathematics, the lowercase formula_1 is used to represent the inclusion function in set theory. The term "iota" is also used to refer to an infinitesimal amount or an insignificant quantity.
Lambda
Lambda (uppercase/lowercase Λ λ) is a letter of the Greek alphabet. It is used to represent the "l" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 30. Letters that came from it include the Roman L and Cyrillic Л.
In mathematics, the lowercase λ is used as a variable for eigenvalues in linear algebra, and as the parameter of both exponential distribution and Poisson distribution. In physics, the same symbol is used as a variable representing wavelength.
Mu (letter)
Mu (uppercase/lowercase Μ μ) is a letter of the Greek alphabet used to represent the "m" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 40. Letters that came from it include the Roman M and Cyrillic М.
In mathematics and statistics, the lowercase μ is used to represent population mean and the Möbius function. It is also used to represent coefficient of friction, micrometre and muon in physics.
Coat of arms of Haiti
The first coat of arms of Haiti was created in 1807, and has appeared in its current form since 1986.
It has a palm, with several flags at its sides, and two cannons on a green lawn. On the lawn there are several objects, such as musical instruments (a snare drum and bugles), guns, and ship anchors. Above the palm tree, there is a Phrygian cap placed as a symbol of freedom.
The ribbon on the bottom displays the national motto: "L'Union Fait La Force" (French for "Union Makes Strength").
Nu (letter)
Nu (uppercase/lowercase Ν ν) is a letter of the Greek alphabet used to represent the "n" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 50. Letters that came from it include the Roman N and Cyrillic Н.
