A specimen is a sample of something, like a specimen of blood or body tissue that is taken for medical testing. The noun specimen comes from the Latin word specere, meaning âto look.â Biologists collect specimens so they can get a better look at something to study it. The idea is that, with a good specimen, you can learn about an entire group: it's a good representation. That meaning is echoed in the slang use of specimen, a strong, healthy and attractive person.
A microscope (from the Ancient Greek: Î¼Î¹ÎºÏÏÏ, mikrÃ³s, small and ÏÎºÎ¿ÏÎµá¿Î½, skopeÃ®n, to look or see) is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes. The most common (and the first to be invented) is the optical microscope, which uses light to image the sample.
