Choking alone (without back blows) to assist a choking victim, is referred to as "The Heimlich Maneuver." The purpose of abdominal thrusts is to create pressure that will expel any object lodged in the airway upwards to relive the obstruction. The Heimlich Maneuver specifically excludes back blows; its inventor, Dr. Henry Heimlich, believed that back blows were likely to cause an airway obstruction to become more deeply lodged in the victim's airway. So, while abdominal thrusts are part of other choking victim protocols, the Heimlich Maneuver uses only abdominal thrusts to attempt to dislodge airway obstructions. The American Red Cross recommends
What Is Life? can be viewed as a well-reasoned theoretical prediction of what biologists should have been looking for during their search for genetic material. Both James D. Watson, and Francis Crick, who jointly proposed the double helix structure of DNA based on X-ray diffraction experiments by Rosalind Franklin, credited Schrödinger's book with presenting an early theoretical description of how the storage of genetic information would work, and each independently acknowledged the book as a source of inspiration for their initial researches. The book is based on lectures delivered under the auspices of the Institute at Trinity College, Dublin, in February 1943 and
