A museum curator is digitizing a collection of ancient telescopes, including 3 refracting telescopes from the 1700s rated at 12.5 cm, 18.3 cm, and 15.7 cm in length, and 2 reflecting telescopes averaging 24.6 cm in length. What is the mean length of all telescopes in the digital archive?

**Unlocking History: A Museum’s Digital Journey Through Ancient Telescopes** In an era where digital preservation bridges past and present, one U.S.-based museum is turning centuries-old astronomical tools into accessible data. A curator is digitizing a rich collection of ancient telescopes—three 18th-century refracting instruments measuring 12.5 cm, 18.3 cm, and 15.7 centimeters in length—alongside two reflecting telescopes with an average size of 24.6 cm. This effort sparks quiet interest: why is a quiet digitization effort becoming a quiet point of curiosity among history and science enthusiasts? As cultural institutions leverage advanced imaging and cataloging technologies, public engagement with preserved heritage is evolving—driven by the desire to explore, learn, and connect with scientific innovation across time. This collection offers more than historical value; it represents a tangible shift toward open access to scientific heritage. The digitization project captures each telescope’s physical dimensions with precision, and our focus today is on a foundational quantitative insight: what is the mean length of all telescopes in the archive? By exploring this calculation, readers gain a clear example of how museums use data to tell stories—without relying on sensationalism or technical jargon. ---
