why are three letter names considered to be powerful?

They are not powerful, but in some business circles are called “power names” because for humans names, they are short and easy to remember.\nThe concept of “power names” comes from the Kabbalah and the 72 names of Divinity.  See the site below:

No special reason. All letters have been used in physics.\nRather arbitrary chosen.\n\nTh

If people didn't have names, you would have a hard time calling someone over!  But names have been something that cavemen have created.  A tradition 1,000,000 years old, it's kind of hard to break this tradition!  But instead of names, people and movies and stuff call robots by letters and numbers.  I don't think they name people after numers because it would be hard to memorize, and the names would be booooooooooring!

One is three, one is two.  Three is more advanced, and therefore inherently more complex.\n\n:-p

I got plenty of D's... \nSo, I know them to exist.\n\nIf you mean E's...\nThe reason is that folks would confuse an E with "excellent", and that would not fit the \nSystem of Letter Grading as intended.

The first two are P and T.  (every third letter spelling out "Happy" and "Birthday")  I don't know the name you are trying to spell with NEO, though.

666 as a name or word\n\nAnother interpretation is that 666 is actually some kind of code based on the letters of someone's name or a word. This sparks great public interest since it seems to provide some way to identify the Antichrist. Numerologists like to devise clever ways of assigning numbers to letters so that the letters of a name will add up to this symbolic number. Probably the best-known scheme has A=100, B=101, and so on. With this code, the name "HITLER" adds up to 666. Another commonly cited example is President Ronald Wilson Reagan, where counting the letters of his first, middle, and last name lead to 666. While these ideas are intriguing, they usually require many specific preconditions, like having to start with 100, numbering the surname only, etc. (even though in the former case, you can also number a=1, b=2, and so on and decode his initials 'A' and 'H' as 18, which of course equals 6+6+6.) By adapting the rules however, it is possible to connect most if not all names to the evil number. See also Vicarius Filii Dei. More convincing interpretations invoke more than mathematics to prove their point.\n\n    * For example, scholars who believe the Book of Revelation refers to real people and events argue that the number represents the value of Nero or Neron Caesar (נרון קסר, Nrwn Qsr*, pronounced "Neron Qesar") in Hebrew letters, which also have numerical values under the form of numerology called Gematria (note that Hebrew is written from right to left):

There is a form of writing known as angelic script, also called the celestial alphabet. This is bred from alchemical writings with ties to hassidic and orthodox hebrew practice. From it are derived seals and sigils. Due to the number of angels, not all have their names written in specific seals and sigils. Also since the seals are usually used in specific practice, the higher angels are the ones called upon for protection/guidance/help/so forth.\n\nFor all intensive purposes though, the hierarchy, in specific the kabbalah (the sephirotic system of names) would be the best way to go, as it holds very closely with core orthodox hebrew teachings, which is where angels orginated.\n\nCheck the links, its interesting stuff.

there are different reasons. 3 is a very powerful number in a lot of cultures. also, in fairy tales they like to isolate people, things, etc. having thins come in 3s allow them to create a patten, and then have the third person or thing break this pattern.

It means "to the power of". Used for indices \n\neg. 4^5 is 4 to the power of 5

it means "raised to the power of".\nthat is, 2^3 means "2 raised to the power of 3" or "2 cubed" \n(2^3 = 2*2*2 = 8)\n\nwhile writing, the index is a superscript of the base. In the above example, 3 will be written as the superscript of 2.\nBut when such a representation is not possible, say while typing, a circumflex (^) is used as explained above.

6- for the number of letters in your name :)

Probably in order to preserve the correct pronunciation. The letter 'Y' tends to elide with vowels which follow it. Thus the superlative of 'hardy' ('hardiest' e.g. perrennials) would be pronounced as in 'yes' or 'yeast' if spelt with a 'Y' - hardYEST.

Yeah because everything always happens in three. Well at least I have always believed three is the magic number. Other people might think otherwise.

I think it's just the using of letters. Just like unknowns are usually called x, y, stuff like that.

I know it has already been answered but I"ll take a chance with something different. Ok 3 to the third power plus two would be 3 to the fifth power which is 243.\n :)

It's true -- a lot of these words seem to come from Latin -- which had a love affair with the V (in vino veritas; veni, vidi, vici).  However, vim, vigor and voluptous are rather nice words of power and excess.\n\nMaybe it's the little buzz you get when a "v" passes through your lips?\n\nVast.  Victory. Vanity.  Hmmm. They all do have a little sting to them, don't they?
