# How can I write the reduced planck's constant in Socratic's math notation?

##
Planck's constant, #h# , is a commonly used physical constant.

However equally common (really, more common in any QM applications), is the reduced planck's constant #h/(2pi)# .

It is denoted by:

Though a horizontal bar through the "h" would work fine as well.

I did try "hbar" but unfortunately it ...

Here's an approach to use to add that symbol. Go to any web page that lists the symbol and simply go **CTRL + C**, then head back to the editor and hit **CTRL + V**.

Add some hashtags to get it to format and you're done!

For example, I found the symbol here

https://en.wikipedia.org/wiki/Planck_constant

Here's how the symbol would look in the editor

without hashtagsħ

with hashtags

#ħ#

You can thus use it as you would any other math symbol.

without hashtagsħ = h/(2pi)

with hashtags

#ħ = h/(2pi)#

You can also get the symbol in MS Word by using its UNICODE tag

U+0127

and go for the same copy / paste + hashtags routine.
