Instead of the tilde “˜” and the lowercase “n”, you should see the letter ñ. To type this symbol on your Mac, hold down the “option” key and press the “n” key. The squiggly-line symbol is used mainly in mathematics but can also be used as a special character in word processing programs or text editors (especially under Unix). It can be confusing that there are two completely different ways to generate a ~ over the letter n. Despite its name, this symbol has nothing to do with the letter o - it’s just a sideways squiggle on top of a lowercase n.

How to Make the n With the Squiggly Line Over it on a Macbook?Ī squiggly line or a tilde (~) above the letter n is called an “overline” in typography. It’s an incredibly useful shorthand way of denoting complicated and connected chemical reactions so researchers can focus more closely on what they need to understand to make scientific discoveries. This symbol indicates that structural changes may occur on one side of the equation that is either unknown to the scientist or not essential for further understanding.įor example, scientists can use this squiggly line symbol to denote a mixture without drawing out each isomer when studying mixtures of isomers. In organic chemistry, a wavy line symbol is a vital tool for representing complex molecules. What Does a Squiggly Line Mean in Organic Chemistry? The length and direction of the squiggle determine how fast or slow each note will be. It indicates that notes of the chord are played rapidly one after the other instead of simultaneously (like in a strummed chord). The line in music notation for an arpeggio is squiggly in front of the chord.
Understanding the significance of “?” in mathematics can be crucial for thoroughly comprehending mathematical equations. In other words, it differs from the symbols typically used for negation in logic or similar applications. It’s important to note that the approximation defined by this symbol is reflexive and symmetric but not transitive. This symbol indicates that one number is approximately equal to another. In math, a squiggly line commonly referred to as “?” often appears in equations. It’s also much harder to type.īut if you’re a cool, contemporary teenager, squiggly lines convey the desired impression of a tilde in a tone far better than the scarily old-fashioned ‘about’ or ‘approximately’ do. You could replace the squiggly line with the word ‘about’ or ‘approximately.’ It means almost the same, just with more syllables. That remained the case until 1918 when the Spanish alphabet was reformed, and the ñ (used for all instances of “n” doubling in some languages) became an official character. Interestingly, the symbol has a name: the tilde.Īround the 12th century, Spanish scribes began using a squiggly line over letters to indicate they were doubled to use less paper.Īround 1522, this practice became specific to indicate only an “n” was being doubled.
