SCIENCE TRIVIA XV

141) Who won a Nobel Prize in Chemistry in 2009 for studies of the structure and function of the ribosome?


Ada E. Yonath was the first woman from the Middle East to win a Nobel prize in the sciences.

142) What aquatic biologist is widely credited with helping launch the environmental movement?


Rachel Carson's most well-known book, Silent Spring, described the harmful effects of pesticides on the environment. In 2012, the book was designated a National Historic Chemical Landmark by the American Chemical Society for its role in the development of the modern environmental movement.

143) What is the standard unit of kinetic energy?


One joule in everyday life represents approximately the energy required to lift a medium-sized tomato (100 g) 1 meter vertically from the surface of the Earth.

144) What branch of science is concerned with the interaction between matter and electromagnetic radiation?


Spectroscopy is the study of the interaction between matter and electromagnetic radiation.

145) Which of the following is the hottest?


The electricity of a lightning strike does not have a temperature, per se, but the air around a bolt of lightning can reach a temperature of 54,000 degrees Fahrenheit, which is 5 times hotter than the surface of the sun which is a mere 10,000 degrees Fahrenheit. The central region of the sun, however, is much hotter than lightning at 27 million degrees Fahrenheit.

146) In 2012, what new molecule was discovered by a 10-year -old in science class?


Tetranitratoxycarbon is a hypothetically-possible molecule, unknown to science until ten-year-old Clara Lazen (a fifth-grader in Kansas City, Missouri) assembled a model of it in her science class in 2012. As an oxygen-rich compound of carbon and nitrogen, it is similar to nitroglycerin and is predicted to have explosive properties.

147) What is the energy an object possesses due to its motion?


Kinetic energy is the energy an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

148) What is the average number of readers for a published scientific paper?


There are a lot of scientific papers out there. One estimate puts the count at 1.8 million articles published each year, in about 28,000 journals. Who actually reads those papers? According to one 2007 study, not many people: half of academic papers are read only by their authors and journal editors, and the average number of readers for a published scientific paper is only 0.6.

149) What is the scientific term for brain freeze?


Brain freeze, or sphenopalatine ganglioneuralgia is a form of headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream.

150) What do scientists use to clean up radioactive waste?


Scientists have discovered that sunflowers can pull radioactive contaminants out of the soil.
