Thomas Edison is credited with inventing the light bulb. He developed a practical and commercially viable incandescent light bulb in 1879, which revolutionized the way we illuminate our surroundings. Edison's light bulb used a carbon filament that could last for hours, making it a significant improvement over previous designs. His invention played a crucial role in the widespread adoption of electric lighting and had a profound impact on society, transforming the way we live and work.

Neil Armstrong was the first person to walk on the moon on July 20, 1969. He was an American astronaut and a part of the Apollo 11 mission. Armstrong made history by taking the first step onto the lunar surface, famously saying, "That's one small step for man, one giant leap for mankind." His achievement marked a significant milestone in space exploration and solidified his place as a legendary figure in human history.

Galileo is credited with inventing the telescope. He was an Italian astronomer and physicist who made significant contributions to the field of astronomy. In 1609, he constructed a telescope and used it to observe the moon, planets, and stars. His observations revolutionized our understanding of the universe and supported the heliocentric model proposed by Copernicus. Galileo's invention of the telescope had a profound impact on the development of astronomy and paved the way for future discoveries in the field.

Charles Darwin is known as the "Father of Evolution" because of his groundbreaking work on the theory of evolution. In his book "On the Origin of Species," Darwin presented evidence for the concept of natural selection, which explains how species evolve and adapt over time. His ideas revolutionized the field of biology and had a profound impact on our understanding of the diversity of life on Earth. Darwin's contributions to the theory of evolution continue to be widely recognized and studied to this day.

Michael Faraday is credited with inventing the electric generator. Faraday was a British scientist who made significant contributions to the field of electromagnetism in the 19th century. He discovered the principle of electromagnetic induction, which is the basis for generating electricity. Faraday's experiments and inventions laid the foundation for the development of electric generators, which are devices that convert mechanical energy into electrical energy. His work revolutionized the field of electricity and had a profound impact on the modern world.

Greg Mendel is known as the "Father of Genetics" because of his groundbreaking work with pea plants. He conducted experiments in the mid-19th century where he crossbred different varieties of pea plants and carefully observed the traits that were passed down to the offspring. Through his experiments, Mendel discovered the basic principles of inheritance, including the concepts of dominant and recessive traits. His work laid the foundation for modern genetics and revolutionized our understanding of how traits are inherited from one generation to the next.

Ohms discovered that "resistance equals voltage, divided by current." He formulated Ohm's law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This fundamental relationship between voltage, current, and resistance is widely used in electrical and electronic circuits.

Robert Hooke is known as the "father of the cell theory" because he was the first to observe and describe cells. When he looked at cork under a microscope, he saw small compartments that he called "cells" due to their resemblance to small rooms. Hooke's observations and naming of cells laid the foundation for the development of the cell theory, which states that all living organisms are composed of cells.

Leevwenhooke is not a known inventor of the microscope. The correct answer is Antonie van Leeuwenhoek. He was a Dutch scientist who is commonly credited with inventing the microscope in the late 17th century. Leeuwenhoek's microscopes were simple but highly effective, allowing him to make groundbreaking observations of microorganisms and other microscopic structures. His contributions to the field of microscopy were instrumental in advancing our understanding of the microscopic world.

Ptolemy is the correct answer because he was an ancient Greek astronomer and mathematician who proposed the geocentric model of the universe, which stated that the Earth was the center of the solar system. This model dominated scientific thought for over a thousand years until it was eventually replaced by the heliocentric model proposed by Copernicus.

Ben Franklin is attributed with discovering and understanding the nature of electricity. Through his famous kite experiment, he demonstrated that lightning is a form of electricity and invented the lightning rod to protect buildings from lightning strikes. Franklin's contributions to the field of electricity laid the foundation for future advancements and understanding in the field.

Mendeleev was responsible for the organization of the elements in a "periodic table" by atomic number. He is credited with creating the first widely recognized periodic table, which arranged the elements in order of increasing atomic mass. However, he also left gaps in the table for undiscovered elements and predicted their properties based on the patterns he observed. His periodic table laid the foundation for the modern periodic table that we use today, which is organized by atomic number rather than atomic mass.

Democritus is credited with the discovery of the "atomos" and the idea that it is indivisible. He proposed that all matter is made up of tiny, indivisible particles called atoms. This theory challenged the prevailing belief at the time that matter could be infinitely divided. Democritus' ideas laid the foundation for modern atomic theory and greatly influenced the development of scientific thought.

Bohr was responsible for the model that had "orbits" around the nucleus of the atom. This model, known as the Bohr model, proposed that electrons orbit the nucleus in specific energy levels or shells. It was a significant development in understanding the structure of the atom and explained phenomena such as atomic spectra. This model also laid the foundation for further advancements in quantum mechanics and helped shape our understanding of atomic structure.

Llnnaeus is the correct answer because he is the scientist who developed the binomial nomenclature system, which assigns two names to each organism - the genus and species names. This system is still widely used today in the field of biology to classify and identify different species.

Dalton is considered the "Father of Atomic Theory" because he proposed the first modern atomic theory in the early 19th century. His theory stated that all matter is made up of tiny indivisible particles called atoms, which combine to form compounds in fixed ratios. Dalton's theory also introduced the concept of conservation of mass in chemical reactions and provided a framework for understanding the behavior of gases. His work laid the foundation for the development of modern chemistry and our understanding of the structure and properties of matter.

Thomson's model of the atom, also known as the "plum pudding model" or "blueberry muffin model," proposed that the atom is a positively charged sphere with negatively charged electrons embedded within it, similar to the way plums or blueberries are embedded in a muffin or pudding. This model suggested that the atom is mostly made up of positive charge with small negatively charged electrons scattered throughout. This model was later disproven by Rutherford's gold foil experiment, which led to the discovery of the atomic nucleus.

Archimedes is the correct answer because he was the scientist responsible for the principle of buoyancy. This principle states that when a body is submerged in a fluid, it loses weight equal to the weight of the fluid displaced by the body. Archimedes discovered this principle while he was in a bathtub and realized that the water level rose as he got in, demonstrating that his body was displacing an equal volume of water. This principle is fundamental to our understanding of buoyancy and is still used in various applications today.

Robert Boyle stated that "the volume of a given mass of gas (the temperature being constant) varies inversely as the pressure; or, that the pressure and volume of a gas are inversely proportional."

Daniel Bernouilli (1700-82) is the correct answer because he was responsible for explaining the principle of flight and the relationship between fluid velocity and pressure. This principle, known as Bernoulli's principle, states that as the velocity of a fluid increases, its pressure decreases. Archimedes, Niels Bohr, and Robert Boyle were not specifically known for their contributions to the principle of flight or this specific relationship between fluid velocity and pressure.
