 Jupyter notebook은 Jupyter 프로젝트를 위한 사용자 언어에 독립적인 HTML 응용 프로그램입니다.
 2015년에 Jupyter notebook은 IPython 코드 기반의 The Big Split™ 의 일부분으로 시작되었습니다.
-IPython 3는 *IPython notebook* 과 같은 사용자 언어에 독립적인 코드와 *IPython kernel for Python* 과 같은 특정 언어 기반의 코드의 기능을 가지고 출시되었습니다.
+IPython 3는 _IPython notebook_ 과 같은 사용자 언어에 독립적인 코드와 _IPython kernel for Python_ 과 같은 특정 언어 기반의 코드의 기능을 가지고 출시되었습니다.
