α - The Inverse of the Fine-Structure Constant (1/137) of quantum electrodynamics, a dimensionless pure number that governs the interactions of elementary particles with photons of light and determines the “distance between an atom’s spectral lines, which are like the DNA of the atom.
Since the early 1900s, physicists have postulated that the number could lie at the heart of a grand unified theory, relating theories of electromagnetism, quantum mechanics and, especially, gravity.
There is a most profound and beautiful question associated with the observed coupling constant, e, the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to -0.08542455. (My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to π or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest ... mysteries of physics: a magic number that comes to us with no understanding by man. You might say the "hand of God" wrote that number, and "we don't know how He pushed his pencil." We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!"- Richard Feynman, QED: The Strange Theory of Light and Matter, Princeton University Press, pg. 129
Stable matter, and therefore life and intelligent beings, could not exist if its value were much different. For instance, were α to change by 4%, stellar fusion would not produce carbon, so that carbon-based life would be impossible. If αwere greater than 0.1, stellar fusion would be impossible, and no place in the universe would be warm enough for life as we know it. (Barrow, John D. (2001). "Cosmology, Life, and the Anthropic Principle". Annals of the New York Academy of Sciences. 950, cited at Wikipedia.org).

Methods
These notes are taken from Wikipedia on Gematria, and Notarikon.
Mispar Hechrachi - (absolute value) that uses the full numerical value of the 22 letters. Sometimes it is also called Mispar ha-Panim (face number), as opposed to the more complicated Mispar ha-Akhor (back number).
Mispar Gadol - counts the final forms (sofit) of the Hebrew letters as a continuation of the numerical sequence for the alphabet, with the final letters assigned values from 500 to 900. The same name, Mispar ha-Gadol, is also used for another method, which spells the name of each letter and adds the standard values of the resulting string.
Mispar Katan - calculates the value of each letter, but truncates all of the zeros. It is also sometimes called Mispar Me'ugal.
Mispar Siduri - (ordinal value) with each of the twenty-two letters given a value from one to twenty-two.
Mispar Bone'eh - (building value, also Revu'a, square) is calculated by walking over each letter from the beginning to the end, adding the value of all previous letters and the value of the current letter to the running total. Therefore, the value of the word achat (one) is 1 + (1 + 8) + (1 + 8 + 4) = 23.
Mispar Kidmi (triangular value) uses each letter as the sum of all the standard gematria letter values preceding it. Therefore, the value of Aleph is 1, the value of Bet is 1 + 2 = 3, the value of Gimmel is 1+2+3=6, etc. It's also known as Mispar Meshulash (triangular or tripled number).
Mispar P'rati - calculates the value of each letter as the square of its standard gematria value. Therefore, the value of Aleph is 1 × 1 = 1, the value of Bet is 2 × 2 = 4, the value of gimmel is 3 × 3 = 9, etc. It's also known as Mispar ha-Merubah ha-Prati'.
Mispar ha-Merubah ha-Klali - is the square of the standard absolute value of each word.
Mispar Meshulash - calculates the value of each letter as the cube of their standard value. The same term is more often used for Mispar Kidmi.
Mispar ha-Akhor - The value of each letter is its standard value multiplied by the position of the letter in a word or a phrase in either ascending or descending order. This method is particularly interesting, because the result is sensitive to the order of letters. It is also sometimes called Mispar Meshulash (triangular number).
Mispar Mispari - spells out the standard values of each letter by their Hebrew names ("Achad" (one) is 1+8+4=13 etc.), and then adds up the standard values of the resulting string.
Mispar Shemi - (also Millui letter "filling"), uses the value of each letter as equal to the value of its name.For example, the value of the letter Aleph is (1 + 30 + 80) = 111, Bet is (2 + 10 + 400) = 412, etc. Sometimes the same operation is applied two or more times recursively.
Mispar Ne'elam - (hidden number) spells out the name of each letter without the letter itself (e.g. "Leph" for "Aleph") and adds up the value of the resulting string.
Mispar Katan Mispari - (integral reduced value) is used where the total numerical value of a word is reduced to a single digit. If the sum of the value exceeds 9, the integer values of the total are repeatedly added to produce a single-digit number. The same value will be arrived at regardless of whether it is the absolute values, the ordinal values, or the reduced values that are being counted by methods above.
Mispar Misafi - adds the number of the letters in the word or phrase to their gematria.
Kolel - is the number of words, which is often added to the gematria. In case of one word, the standard value is incremented by one.
Notarikon - נוטריקון
A method of deriving a word, by using each of its initial (Hebrew: ראשי תיבות) or final (Hebrew: סופי תיבות) letters to stand for another, to form a sentence or idea out of the words. Another variation uses the first and last letters, or the two middle letters of a word, in order to form another word.
Rashi uses notarikon seven times in his pirush ("explanation") on Chumash:
Bereishit (Genesis) 15:2 "וּבַגְּמָרָא שֶׁלָּנוּ דָּרְשׁוּ נוֹטְרִיקוֹן, דּוֹלֶה וּמַשְׁקֶה מִתּוֹרַת רַבּוֹ לַאֲחֵרִים"
Bereishit (Genesis) 17:2 "כִּי אַב הֲמוֹן גּוֹיִם. לְשׁוֹן נוֹטְרִיקוֹן שֶׁל שְׁמוֹ"
Bereishit (Genesis) 30:2 "וּמִדְרַשׁ אַגָּדָה יֵשׁ רַבִּים בִּלְשׁוֹן נוֹטָרִיקוֹן"
Bereishit (Genesis) 49:22 "אֶבֶן יִשְׂרָאֵל. לְשׁוֹן נוֹטְרִיקוֹן אָב וּבֵן, ’אֲבָהָן וּבְנִין‘, יַעֲקֹב וּבָנָיו"
Shemot (Exodus) 20:12 "אִם תְּכַבֵּד יַאֲרִיכוּן יָמֶיךָ וְאִם לָאו יִקְצְרוּן. שֶׁדִּבְרֵי תוֹרָה נוֹטְרִיקוֹן הֵם נִדְרָשִׁים, מִכְּלָל הֵן לַאו וּמִכְּלָל לַאו הֵן"
Bamidbar (Numbers) 11:8 "דָּבָר אַחֵר, 'לְשַׁד' לְשׁוֹן נוֹטָרִיקוֹן לַ'יִשׁ שֶׁ'מֶן דְּ'בַשׁ, כְּעִסָּה הַנִּלּוֹשָׁה בְשֶׁמֶן וּקְטוּפָה בִדְבַשׁ."
Bamidbar (Numbers) 22:32 "כִּי יָרַט הַדֶּרֶךְ לְנֶגְדִּי. רַבּוֹתֵינוּ חַכְמֵי הַמִּשְׁנָה דְּרָשׁוּהוּ נוֹטָרִיקוֹן, יָרְאָה, רָאֲתָה, נָטְתָה"
Chilufei Otiyot
Atbash - exchanges each letter in a word or a phrase by opposite letters. Opposite letters are determined by substituting the first letter of the Hebrew alphabet (Aleph) with the last letter (Tav), the second letter (Bet) with the next to last (Shin), etc. The result can be interpreted as a secret message or calculated by the standard gematria methods. A few instances of Atbash are found already in the Hebrew Bible. For example, see Jeremiah 25:26, and 51:41, with Targum and Rashi.
Albam - the alphabet is divided in half, eleven letters in each section. The first letter of the first series is exchanged for the first letter of the second series, the second letter of the first series for the second letter of the second series and so forth.
Achbi - divides the alphabet into two equal groups of eleven letters. Within each group, the first letter is replaced by the last, the second by the tenth, etc.
Ayak Bakar - replaces each letter by another one that has a 10-times-greater value. The final letters usually signify the numbers from 500 to 900. Thousands are reduced to ones (1000 becomes 1, 2000 becomes 2 etc.)
Ofanim - replaces each letter by the last letter of its name (e.g. "Fe" for "Aleph").
Akhas Beta - divides the alphabet into three groups of 7, 7 and 8 letters. Each letter is replaced cyclically by the corresponding letter of the next group. The letter Tav remains the same.
Avgad - replaces each letter by the next one. Tav becomes Aleph. The opposite operation is also used.
