hologram = holo<whole> + gram<written/recorded>
- holo: From Greek holos, meaning "whole" or "complete."
- gram: From Greek gramma, meaning "something written" or "record."
Etymology Origin:
The term hologram combines Greek roots to describe a technology that captures and reproduces a "whole" image in three dimensions. Holo reflects the complete visual representation, while gram refers to the recorded or projected form. Coined in the mid-20th century, the word mirrors advancements in optics and laser technology, where light patterns recreate objects entirely (holistically).
