kaleidoscope (s) (noun)
, kaleidoscopes (pl)
1. An optical toy consisting of a cylinder with mirrors and colored shapes inside that create shifting symmetrical patterns when the end is rotated.
2. A complex set of events or circumstances.
3. From early 19th century, Greek kalos, "beautiful" + eidos, "form"; + scope, "see".
An optical instrument, consisting of from two to four reflecting surfaces placed in a tube, at one end of which is a small compartment containing pieces of colored glass: on looking through the tube, numerous reflections of these are seen, producing brightly-colored symmetrical figures, which may be constantly altered by rotation of the instrument.
, more kaleidoscopic, most kaleidoscopic
Descriptive of a device that exhibits brightly colored and continually varying figures.
1. The recording of a TV program on motion pictures for subsequent use.

koniscope, coniscope, dust counter, Aitken dust counter
An scientific instrument which indicates the presence of dust particles in the atmosphere.
Named after John Aitken (1839-1919), a Scottish physicist and meteorologist, one of the founders of cloud physics and aerosol science who invented the first koniscope.
An apparatus which once was used for measuring the pulse waves or the variation in blood pressure.
Examination of the interior of the stomach through an abdominal incision.
Any instrument used in examining the abdomen; now specifically one in the form of a tube for insertion into the peritoneal cavity in laparoscopy, having a source of light at the inserted end and an optical system for forming at the other end an image of the illuminated region; an endoscope for examining the peritoneal cavity.
The laparoscope is a type of endoscope, the earliest of which, dating from 150 years ago, was a crude tube down which lamplight was reflected. With the advent of fiberoptics in the 1960's and of high-intensity, low-heat, halogen bulbs in the 1970's, endoscopy became clinically practical.
Typically, in laparoscopy, the abdomen is first inflated with carbon dioxide, and the laparoscope passed through a small incision in the abdominal wall. The device is frequently used to view the female reproductive organs, in particular where endometriosis or pelvic inflammatory disease is thought to be present, or infertility is suspected because of obstruction of the fallopian tubes by scarring (adhesions).
Fitted with grasping and cutting tools, the laparoscope can perform minor surgery, take tissue samples for biopsy, and remove eggs from the ovaries (as in gamete intrafallopian transfer). Often done on an ambulatory basis, laparoscopy is among the new techniques that have revolutionized modern surgery.
1. Visual examination of the interior of the peritoneal cavity with a laparoscope inserted into it through the abdominal wall or the vagina.
2. An examination of body cavities during certain types of surgery; for example, surgeries to remove fibroid tumors, or gall bladders, are often removed through the navel rather than cutting into the body.
