Scientist: Patent and Sir Frank Whittle
1. Who invented the BALLPOINT PEN?
A. Biro Brothers
Explanation:
The Hungarian brothers, Laszlo and George Biro, made the first ball point pen in 1894. It followed the first workable fountain pen which was invented by L.E. Waterman in 1884.
2. In which decade was the first solid state integrated circuit demonstrated?
A. 1950s
Explanation:
On September 12, 1958, Jack Kilby demonstrated the first working IC while working for Texas Instruments, although the U.S. patent office awarded the first patent for an integrated circuit to Robert Noyce of Fairchild.
3.What J. B. Dunlop invented?
A. Pneumatic rubber tire
Explanation:
Invented in 1887.
4. Which scientist discovered the radioactive element radium?
D. Marie Curie
5. When was barb wire patented?
A. 1874
Explanation:
Joseph F. Glidden was born in New York on Jan. 18, 1812. He invented barbed wire in 1873 and was granted the patent on Nov. 24, 1874. After a three year battle over the patent, which he eventually won, Gidden became known as the "Father of Barbed Wire".
6. What is the name of the CalTech seismologist who invented the scale used to measure the magnitude of earthquakes?
A. Charles Richter
Explanation:
Richter was born on an Ohio farm in 1900. He died in 1985.
7. What Galileo invented?
D. Thermometer
Answer: Option D
Explanation:
Various authors have credited the invention of the thermometer to Cornelius Drebbel, Robert Fludd, Galileo Galilei or Santorio Santorio. The thermometer was not a single invention, however, but a development.
Galileo Galilei also discovered that objects (glass spheres filled with aqueous alcohol) of slightly different densities would rise and fall, which is nowadays the principle of the Galileo thermometer (shown). Today such thermometers are calibrated to a temperature scale.
8. This statesman, politican, scholar, inventor, and one of early presidents of USA invented the swivel chair, the spherical sundial, the moldboard plow, and the cipher wheel.
