Historian Discovers Majority of 17th-Century Scientific Manuscripts Detail Early Experimental Methods A recent study by a leading historian analyzing rare scientific manuscripts has revealed fascinating insights into the origins of experimental science. Through meticulous examination of newly surveyed documents, the historian found that 60% of 480 examined texts date back to the 17th century—a period widely recognized as the dawn of modern scientific inquiry. Of these 17th-century documents, the researcher noted that 25% specifically discuss early experimental methods, offering valuable clues about the methodologies used by pioneering scientists of the era. To calculate how many manuscripts cover experimental approaches, the analysis focuses on the key statistic: 25% of 480. Doing the math:
25% of 480 = 0.25 × 480 = 120 documents
