Inventions, Discoveries and Explorations

The first programmable computer was developed by Konrad Zuse. He was a German engineer and inventor who is considered to be one of the fathers of computer science. In 1936, he developed the Z1, which was the first working programmable computer. The Z1 was a binary, electromechanical computer that could be programmed using punch tape. It was not a commercial success, but it was a major milestone in the development of computers.

Lewis E. Waterman is credited with inventing the modern fountain pen in 1884. The first fountain pens were invented in the early 1700s, but they were not very practical. They were often leaky and difficult to use. Waterman’s pen was the first to use a reliable filling system that prevented leaks. It was also the first pen to use a nib made of gold, which was more durable and gave a smoother writing experience. Waterman’s pen was a commercial success, and it helped to make fountain pens the popular writing instrument that they are today.

Archimedes was a Greek mathematician, physicist, engineer, inventor, astronomer, and geometer. He is considered one of the greatest scientists of all time. Archimedes discovered the law of floatation while taking a bath. He noticed that the water level rose when he got into the bath, and he realized that this was because the water was displaced by his body. He then realized that this principle could be used to determine the density of objects. The law of floatation states that a body immersed in a fluid experiences an upthrust equal to the weight of the fluid displaced. This means that if the weight of the object is greater than the weight of the fluid displaced, the object will sink. If the weight of the object is less than the weight of the fluid displaced, the object will float. The law of floatation is used in many different applications, including the design of ships, submarines, and hot air balloons. It is also used in the construction of dams and other structures that must withstand the force of water.

Louis Pasteur developed the earliest effective vaccine against rabies that was first used to treat a human bite victim on 6 July 1885. The method involved inoculation with homogenates of RABV-infected rabbit spinal cord that had been desiccated progressively in sterile air.
