Inventors and Scientific Discoveries

William Harvey discovered the circulation of blood in 1628, demonstrating that blood flows through the body in a continuous loop pumped by the heart. Edward Jenner developed the smallpox vaccine, Joseph Lister pioneered antiseptic surgery, and 'Jonon Esals' appears to be a misspelling or error.

William Caxton introduced the printing press to England around 1476, becoming the first English printer and publisher. James Arkwright was involved in textile manufacturing, James Watt in steam engines, and Isaac Newton was a physicist and mathematician.

Joseph Lister pioneered antiseptic surgery in 1865 by using carbolic acid (phenol) to sterilize surgical instruments and clean wounds, dramatically reducing infection rates. Edward Jenner developed the smallpox vaccine in the late 18th century, not antiseptic techniques.

John Logie Baird, a Scottish engineer, demonstrated the first working mechanical television system in 1926. While several inventors contributed to television technology (including Philo Farnsworth with electronic television), Baird is widely credited in general knowledge contexts as the television's inventor.

Jonas Salk developed the first successful polio vaccine in 1955, using inactivated virus (IPV). Albert Sabin later developed the oral polio vaccine (OPV). Salk's vaccine was the breakthrough that ended polio epidemics in the United States. Selman Waksman discovered streptomycin, an antibiotic, not a polio vaccine.

James Watt did invent the steam engine, Alexander Graham Bell invented the telephone, and John Logie Baird invented the television. However, penicillin was discovered by Alexander Fleming, not J. Perkins (Perkins is associated with an early refrigeration technique).

László Bíró, a Hungarian journalist, invented the modern ballpoint pen in the 1930s. The key innovation was a tiny ball that rolled to distribute ink as it moved across paper. Waterman is associated with fountain pens, while Oscar and Wilson are not associated with pen inventions.

Orville and Wilbur Wright invented, built, and flew the world's first successful motor-operated airplane in 1903. Balloons were invented much earlier by the Montgolfier brothers in 1783.

Faraday is famous for electromagnetic induction and electrolysis, not diffusion of gases. The other pairs are correct: Roentgen discovered X-rays, Newton formulated gravitation laws, Pasteur founded bacteriology.

Daniel Gabriel Fahrenheit invented the mercury thermometer in 1714, which became known as the doctor's thermometer due to its medical applications. Edison invented the light bulb and phonograph, Galileo invented the thermoscope (precursor to thermometer), and option A is correct.

A.I. Oparin proposed the theory of chemical evolution of life in his 1924 book 'The Origin of Life'. His hypothesis suggested that organic molecules could form from inorganic precursors under early Earth conditions, eventually leading to primitive cells. Darwin proposed biological evolution by natural selection, Lamarck proposed inheritance of acquired characteristics, and Haeckel proposed recapitulation theory - none addressed chemical origins.

Alexander Graham Bell invented the telephone in 1876 and was awarded the first US patent for it. John Logie Baird invented television, Thomas Edison invented the phonograph and improved the light bulb, and James Watt improved the steam engine - none invented the telephone.

Einstein formulated the mass-energy equivalence principle E=mc², showing that mass and energy are interchangeable. This revolutionary concept became a cornerstone of modern physics. Planck contributed to quantum theory, Dalton to atomic theory, and Rutherford to nuclear structure, but none established this specific relationship.

Charles Babbage designed the first mechanical computer, the Analytical Engine, earning him recognition as the 'father of the computer'. Edison worked on electrical devices, Mac Millan was a publisher, and Rangabhashyam is not associated with computing.

Sir Isaac Newton does not have an element named after him, unlike the other three scientists. Rutherfordium (Rf, 104) honors Ernest Rutherford, Seaborgium (Sg, 106) honors Glenn Seaborg, and Curium (Cm, 96) honors Marie Curie. Despite Newton's monumental contributions to physics, no element bears his name.
