In Jewish mythology, it was the letter aleph that was carved into the head of the golem that ultimately gave it life. The main difference between these is that ALEF SYMBOL is part of a left-to-right directionality character set and HEBREW LETTER ALEF is part of a right-to-left directionality character set. ALEF SYMBOL is acompatibility character and these two characters are considered border-linesemantically distinct. It is common to use these characters interchangeably, especially when using a font that supports only one of them. ALEPH – the name of the IBS supercomputer – is the first letter of the Hebrew alphabet which signifies that this is the “one” or “first” supercomputer for IBS and ICCP. In addition, it also means “wind” or “air” and refers to some of the research that is conducted on the supercomputer.

What is the highest aleph?

There is no largest aleph among all alephs. It was shown by Cantor that the set of all alephs is meaningless, i.e., there is no such set. See also Totally well-ordered set; Continuum hypothesis; Set theory; Ordinal number; Cardinal number.

The aleph symbol of metallurgy began in the ancient times with royalties and alchemists studying the properties of metals and mostly gold. Incidentally, another variant runs, “99 bottles of beer on the wall, 99 bottles of beer, Take one down, Put it back up, 99 bottles of beer on the wall” . The Question and Answer section for Aleph is a great resource to ask questions, find answers, and discuss the novel. The Trans-Siberian train from Moscow to Vladivostok is often symbolized as life itself.

The Letter Aleph (א)

AsciiDoc and Markdown are known as “lightweight aleph symbol.” It’s more correct to say Unicode can support over a million “code points” (rather than “characters”). U+2135 and U+05D0 are examples of Unicode code points. The appearance of the Aleph characters in the third column of the tables below depends on the fonts that are installed on your system. If your system does not support a font that contains a character, you will see an empty box or a question mark. If ALEF SYMBOL and HEBREW LETTER ALEF look different from how they look at the FileFormat.Info links above, your browser may be doing font substitution.

How do you type the aleph symbol?

  1. You can use 'ℵ', 'ALEF SYMBOL' (U+2135).
  2. Instead of the usual digit 0 , you can use a zero-like character with left-to-right directionality, such as '〇', 'IDEOGRAPHIC NUMBER ZERO' (U+3007).
  3. The cleanest way is to use the 'LEFT-TO-RIGHT MARK' (U+200E) character (Wikipedia) after the aleph: ‘א‎0’.

Once you release the Alt key, the ℵ symbol will be displayed. This trick will work for other special characters also. To type the ℵ using the keyboard you can the Alt code from the shortcode section. Here are the two simple steps to type the ℵ using Alt code from your keyboard.

In set theory, the Hebrew aleph glyph is used as the symbol to denote the aleph numbers, which represent the cardinality of infinite sets. This notation was introduced by mathematician Georg Cantor. In older mathematics books, the letter aleph is often printed upside down by accident, partly because a Monotype matrix for aleph was mistakenly constructed the wrong way up. The assumption that the cardinality of each infinite set is an aleph number is equivalent over ZF to the existence of a well-ordering of every set, which in turn is equivalent to the axiom of choice.


Make sure you switch on the Num Lock from the keyboard and you the number from the Numpad and not from the top row of the keyboard. Loanwords from Hebrew or Aramaic in Yiddish are spelled as they are in their language of origin. ], but that digraph is not permitted at the beginning of a word in Yiddish orthography, so it is preceded by a silent aleph.

The character is also known as first transfinite cardinal . Each finite set is well-orderable, but does not have an aleph as its cardinality. Is a bijection from the ordinals to the infinite cardinals.

The set of all finite subsets of any given countably infinite set. The cardinality of the natural numbers is ℵ 0 , (read aleph-nought or aleph-zero; the term aleph-null is also sometimes used), the next larger cardinality of a well-orderable set is aleph-one ℵ 1 , ;, then ℵ 2 , and so on. Continuing in this manner, it is possible to define a cardinal number ℵ α , for every ordinal number α , as described below. This character is a Other Letter and LTC is commonly used, that is, in no specific script.

  • This letter is actually the source of the Greek letter Alpha, as you can see by the similarities in the two letters’ names, and the English letter “A,” is therefore ultimately derived from Aleph, as well.
  • This trick will work for other special characters also.
  • Even the utterance of a Hebrew letter, when put upon the air, is like a prayer, a manifestation of praise that is meant for and sent to find the ear of the Almighty himself.
  • These letters are believed to have derived from an Egyptian hieroglyph depicting an ox’s head.
  • This notation was introduced by mathematician Georg Cantor.

Uses with the narrator in the starting of the book, or as Hilal follows with the narrator and Tatiana are part of their understanding of the world. The root of the word Aleph is also connected to many other words in the Hebrew language. The world “eleph,” for example, means a thousand.

On this Wikipedia the language links are at the top of the page across from the article title. In graduate school, I spent many hours using Fontastic to create mathematical fonts while procrastinating writing my thesis. For example, I fiddled a lot with the pixels in my 2ℵ0 character. In 1874 Cantor showed that there is more than one level of infinity and started using ℵ, followed by a subscript, to represent different levels of infinity. The two tables below list some ways to insert these characters. You can use the third column of these tables to see how the web browser you are using right now supports these different markup methods.


Some publications use a silent aleph adjacent to such vowels in the middle of a word as well when necessary to avoid ambiguity. In Modern Hebrew, the frequency of the usage of alef, out of all the letters, is 4.94%. Despite the name it does not correspond to an aleph in cognate Semitic words, where the single “reed” hieroglyph is found instead. Common markup languages include AsciiDoc, HTML, LaTeX, Markdown, SGML, XHTML, and XML.

Unicode has two code points for the Hebrew letter aleph. This character should be used for the mathematical symbol since ETH it retains the left-to-right orientation of the text. The cardinality of any infinite ordinal number is an aleph number. Any set whose cardinality is an aleph is equinumerous with an ordinal and is thus well-orderable. Symbol for the transfinite enumeration of the infinite cardinal numbers in order of magnitude, a function mapping ordinal numbers to infinite cardinals.

The set theory symbol refers to a set having the same cardinal number as the “small” infinite set of integers. The symbol is often pronounced “aleph-null” rather than “aleph-zero,” probably because Null is the word for “zero” in Georg Cantor’s native language of German. It is sometimes also pronounced “aleph-zero” or “aleph-naught,” the latter of which is also spelled “aleph-nought.” Since it is the first letter, it is at the head of the alef-bet, like a king. Even the utterance of a Hebrew letter, when put upon the air, is like a prayer, a manifestation of praise that is meant for and sent to find the ear of the Almighty himself. But for non-Hebrew readers, these symbols by themselves are meaningless.
