Best Ball Rebounders: A Brief History
The first known mention of a “ball” was found in the writings of ancient Chinese philosopher Lao Tzu (c. 551 BC). His writings were discovered during the Ming Dynasty. According to him, there are four elements or elements of which the world is made up: Fire, Water, Wood and Earth. These four elements have no fixed shape, but they do not exist in isolation either.
They all interact with each other.
In the same way, basketball players have been described as being like water; they move around fluidly and freely. Their movement is based on their ability to absorb energy from the air through their bodies and release it into the ball.
A similar description of a ball was given by Greek mathematician Archimedes (341–212 BC) in his book On the Method of His Time. He wrote that a sphere is the most stable form of matter, and that if two spheres are placed together, they will remain connected forever. The only problem with this theory is that it doesn’t explain why two spheres would stay connected even when one breaks off and floats away.
This problem was not discovered until the mid-1500s by Sir Isaac Newton (1642-1727). His theory of gravity not only solved this problem, but also provided a new insight into the nature of matter. It also led to his discovery of the many properties of gravity and its effects on objects in space.
Newton’s theory of gravity involved two main concepts. The first concept states that every object in the world has gravity. The other states that the force of gravity is directly proportional to the amount of matter in each object. The theory also maintains that for any two objects in the world, the force of gravity between them is always attractive and acts along the line that connects the centers of both objects.
In 1755, French mathematician and historian Edme Mentle d’Alembert (1717-1783) formalized the concept of matter. He described the nature and behavior of matter in an attempt to understand Sir Isaac’s theory of matter. He concluded that every object in the world is made up of infinitely small and invisible particles that he called “atoms.”
The most important concept of d’Almbert’s atom theory is the idea that all matter is made up of different combinations and arrangements of atoms.He also said that there are only a few types of atoms that make up everything in the world.
This theory was later modified in 1811 by English chemist and physicist John Dalton (1766-1844). He suggested that atoms of a particular element are all identical and unchangeable, meaning that there is no difference between one atom and another of that particular element. He also said that an atom cannot be created or destroyed, only joined together or taken apart.
Dalton’s theory was later proved when English physicist Ernest Rutherford (1871-1937) discovered the nucleus at the center of an atom in 1911. Of course, Rutherford’s research was only made possible because of the work of Robert A. Millikan (1868-1953), who invented the first accurate method for measuring the charge on an electron.
The discovery of electrons led to the invention of a new machine called a “voltaic pile” by Italian physicist Alessandro Volta (1745-1827). The voltaic pile is a battery that works by allowing electrical charge to build up on two different metal rods. This allowed for the first electrical experiments to begin.
Later in the nineteenth century, German-born British physicist John Ambrose Fleming (1849-1945) invented the “thermionic valve” or “electronic valve.” This helped to improve the electron tube, which is a metal container that holds a hot object, such as a cathode (a negatively charged electrode), that emits electrons. These electrons can then be directed by a magnetic field to a positively charged electrode, called a plate.
These devices are still in use today!
The next step was taken by Scottish physicist James Clerk Maxwell (1831-1879). He worked out a set of equations that describe all of the basic laws of electricity and magnetism. He was the first person in history to unite light with electricity and magnetism. His work also provided an important mathematical tool for understanding the interactions of subatomic particles in terms of 4 quantum numbers (called “quaternions”).
In 1891, German-born American physicist Karl Guthe Jansky (1889-1935) invented the first radio telescope.
The twentieth century saw much advancement in the fields of electronics, computers, and software. The first computer was created at the University of Pennsylvania by John Presper Eckert (1919-1995) and John W. Mauchly (1907-1980) in 1946. It was called the “ENIAC” (which stands for Electrical Numerical Integrator And Computer). It could add or subtract 5,000 numbers in one second!
It was 10 feet high, covered about 1,800 square feet, and weighed around 30 tons. It had more than 500,000 soldered parts!
In 1965, American computer scientist (and a future Nobel prize winner) Robert Glen “Bob” Trapp (b. 1927) invented the first laser printer.
The last half of the twentieth century also saw the rise of the personal computer. In the 1970s, this began with inventions such as the “Altair 8800” (which was released in January, 1975). This was followed by inventions like the “Apple I” in 1976 and the “Commodore PET” in 1977.
These computers were not like their modern day successors. In fact, they only held a maximum of around 4 kilobytes of memory! (Most modern computers have around 2,000,000 kilobytes of memory!)
However, these early inventions are the simplest roots of what we have today.
It is this technology that allowed me to create and send you this message. It also allows us to touch base with our various colony planets and all other Auvahrs in the galaxy — even if we can’t meet them face to face.
It is a great time to be an Auvahr!
