Science Experiment: The Monster Study

The Monster Study is the name given to a stuttering experiment performed on 22 orphan children in Davenport, Iowa in 1939. It was conducted by Wendell Johnson at the University of Iowa. Johnson chose one of his graduate students, Mary Tudor, to conduct the experiment, and he supervised her research. After placing the children in control and experimental groups, Tudor gave positive speech therapy to half of the children, praising the fluency of their speech, and negative speech therapy to the other half, belittling the children for every speech imperfection and telling them they were stutterers.

Wax Anatomical Model of a Human Head, Europe, 1801-1900

This wax model of a human head shows the internal structure of the brain, complete with its protective covering, the meninges, the eye, cheek, neck and jaw. Wax models were used for teaching anatomy to medical students or as part of popular anatomy shows. 

They were used to pick out and emphasize specific features of the body, making their structure and function easier to understand, especially at a time when few bodies were available for dissection. The model was donated by the Department of Human Anatomy at the University of Oxford. (Source)

Clouds of Jupiter

Jupiter shows a pattern of clouds of white, brown, and orange. And then there is the Great Red Spot. The Great Red Spot is the largest of the clouds of Jupiter. Other cloud shapes include eddy shapes, white ovals, brown ovals, and brown barges.

There are three layers of clouds on Jupiter, and each one is composed of different molecules.  At one level there are clouds of ammonia, at another level there are clouds made of ammonia and sulfur, and at a third level there are clouds of water (H2O).

Stabbing His Own Heart

Werner Theodor Otto Forssmann, a German surgical trainee in 1929, is famous for an experiment he performed on himself. Without any direction, he put himself under local anesthetic, incised a hole in his arm and pushed a catheter all the way up his limb and shoved it into his heart. He performed the procedure on himself with two feet of cable after which he walked to the X-ray room. He was fired after this stunt, but was awarded the 1956 Nobel Prize for Medicine for developing a procedure that allowed for cardiac catheterization. (Source)
