Within Modern Orthodox Judaism, the Union of Orthodox Congregations created the National Conference of Synagogue Youth (NCSY) to reach Jewish teenagers in public schools. Founded by Rabbi Pinchas Stolper, himself a noted charismatic speaker and writer, the movement also developed its in-house literature geared to the newly observant mainly written by Rabbi Aryeh Kaplan. In addition, many Modern Orthodox professors have developed and used a sophisticated modern terminology to present Judaism in a scientific manner. Their books on Jewish sciences are the most readily accessible.
