Halacha:

Science & Medicine 

Description

Derech HaTeva is a publication of the undergraduate students of Stern College for Women. <br> Editors in Chief: Shoshana Simpson, Adina Zinkin <br><br> Witnesses are only needed when there is an element of doubt with regard to the case and therefore clarification is required. However, if all matters are apparent and straight forward, then testimony by witnesses is obviated. The question that many rabbanim contemplated is whether scientific evidence sufficiently constitutes yediya b'lo reiya.
