A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is minced up, or morcellated, into smaller pieces inside the woman's belly cavity in order to extract from the abdomen.
What disease does Steven Hawking suffer from? He has a muscular dystrophy cognate to amyotrophic lateral sclerosis (ALS), the latter being also known as Lou Gehrig's disease. Edit
Hawking has devoted most of his life to studying these questions. Initially, cosmologists believed the holes were like a cosmic vacuum cleaner, sucking up everything in their path. Hawking revolutionized the study of the holes when he demonstrated in 1976 that, under the strange rules of quantum physics, once black holes form they start to evaporate away, radiating energy and losing mass in the process.
