    Galileo Galilei (1564-1642) was an Italian scientist. Using precise measurements, he created the Law of Falling Bodies. He made a telescope, which he used to study lunar craters. He discovered four moons in the sky around Jupiter. This made him the first scientist to use a telescope to make important astronomical discoveries. It was the year 1609, and Galileo has just heard of the invention of the telescope in Holland. With only a few details, he was able to build his own – which was vastly superior! He had heard of a new theory, known as the sun-centered (or heliocentric) theory, which was proposed by Nicholas Copernicus. Using his new tool, he agreed that the planets were in orbit around the sun. At the time, it was widely believed that planets, the sun, and the moon all circled around Earth. Galileo was a university professor, and was required to teach the beliefs of the time rather than this new sun-centered theory. When it was heard that he was telling his students about this new theory, he was sentenced to life in prison by the church. However, since he was quite aged by this point, it was agreed that he could live out his sentence on house arrest. Galileo is well respected within the science community, largely because of his excellent scientific techniques. Many believe that his methods opened the door for future scientists. His technique sounds quite simple to us: First, he analyzed a problem using common-sense and everyday experiences. Then, he analyzed the problem using mathematical techniques. Sir Isaac Newton (who was born the year Galileo died) used Galileo’s “Law of Inertia” as the basis for his “First Law of Motion.” Galileo became blind at the age of 72. He died in 1642.

    People always wanted to fly and tried to build different mechanisms to make their dream come true. Read the article about Wright brothers and their invention - the first manned, powered, heavier-than-air aircraft and choose the correct answer.

  • 10. 

    Orville and Wilbur Wright were inventors and the aviation pioneers credited with the invention of the first airplane, heavier-than-air, that had a successful flight. Wilbur was born in 1867 in Indiana; Orville in 1871 in Ohio. The two brothers were interested in technology and mechanics from an early age – Orville had designed and built his own printing press by his junior year of high school. Bicycles became a big trend in the late 1800s, so the brothers used their mechanical knowledge to open the Wright Сycle Shop in 1892. Soon after, they started making and selling their own bicycles for people to buy. The more they worked with bicycles, the more they became interested in transportation and, eventually, the idea of human flight. At the time, people had only recently begun experimenting with flights. People around the world were building gliders and other flying mechanisms, and Orville and Wilbur decided to see if they could use their skills to make a working flying machine. Before building any airplanes, Orville and Wilbur read everything they could find on flying and flight. They also studied the way birds moved when they flew. This gave them the idea to use “wing warping” in their models, a twist which let the wings of their planes and gliders move. The famous first flight was made by Orville because he won a coin toss with his brother. The flight took place at Kitty Hawk North Carolina on December 17, 1903. They chose Kitty Hawk because it had a hill, good breezes, and was sandy which would help soften the landing in case of a crash. The first flight lasted for 12 seconds and they flew for 120 feet. The Wright Brothers didn't stop with this first flight. They continued to perfect their craft. They managed to patent their invention and they sold their patents to the Wright company for $100,000. In 1912, Wilbur was diagnosed with typhoid fever and died. Orville spent three decades of his life serving in different Aeronautics committees.He died in 1948 after his second heart attack.

    Galileo was the first man to prove that planets, the sun, and the moon all circled around Earth.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Galileo was not the first man to prove that planets, the sun, and the moon all circled around Earth. In fact, he was the one who provided evidence to support the heliocentric model, which states that the Earth and other planets revolve around the sun. This model was proposed by Nicolaus Copernicus. Galileo's observations using his telescope further supported this heliocentric view, challenging the prevailing geocentric belief that the Earth was at the center of the universe. Therefore, the statement that Galileo was the first to prove planets, the sun, and the moon circled around Earth is false.

    Phosphorus is called the "element of life and thought" because it is an essential component of DNA, RNA, and ATP, which are all vital for life. It is also present in phospholipids, which are the main building blocks of cell membranes. Additionally, phosphorus plays a crucial role in energy transfer and storage within cells. In terms of thought, phosphorus is involved in the synthesis and release of neurotransmitters in the brain, which are responsible for transmitting signals between nerve cells. Therefore, phosphorus is closely associated with both the biological processes of life and the cognitive processes of thought.

    What chemical element does not have a permanent residence in the Periodic System of Chemical Elements?

    • A.

      Helium

    • B.

      Nitrogen

    • C.

      Hydrogen

    • D.

      Neon

    Correct Answer
    C. Hydrogen
    Explanation
    Hydrogen is the chemical element that does not have a permanent residence in the Periodic System of Chemical Elements. This is because hydrogen, unlike other elements, does not fit neatly into any specific group or category in the periodic table. It has unique properties that make it difficult to classify, and its placement in the periodic table has been a subject of debate among scientists. Therefore, hydrogen is considered to not have a permanent residence in the periodic system.

    Which of these is not one of the groups of the Periodic Table?

    • A.

      Alkali metals

    • B.

      Noble gases

    • C.

      Non-metals

    • D.

      Transition metals

    Correct Answer
    C. Non-metals
    Explanation
    The Periodic Table is divided into several groups based on the properties of the elements. Alkali metals, noble gases, and transition metals are all groups on the Periodic Table. Non-metals, on the other hand, are not a specific group on the Periodic Table. Non-metals are a classification of elements based on their physical and chemical properties, but they are not grouped together in a specific section of the Periodic Table like alkali metals, noble gases, and transition metals are.

    In a liquid the particles are arranged ....

    • A.

      Regularly spaced and freely moving

    • B.

      Irregularly and less tightly packed, they are free to move

    • C.

      Regularly and tightly packed, they are not free to move

    • D.

      Irregularly and very spaced out, they are free to move

    Correct Answer
    B. Irregularly and less tightly packed, they are free to move
    Explanation
    In a liquid, the particles are arranged irregularly and less tightly packed, allowing them to move freely. Unlike in a solid where the particles are tightly packed and fixed in position, the particles in a liquid have more space between them and can move around more easily. This explains why liquids can flow and take the shape of their container.
