Harvard Mark I
The early 1940’s were known for the worldwide war. This war did change history. In the year 1944 an invention was created. It has revolutionized the world today. This piece of technology happens to be a computer.
Howard H. Aiken is credited to inventing the Harvard Mark I computer in the year 1944. The first computer was actually invented in 1941 in Germany which the name of it is the Zuse Z3. The Harvard Mark I is a significant computer because it was American made and this contraption had a great ability in doing calculations. The creator, Howard H. Aiken, was born in Hoboken, New Jersey. In 1939 he obtained his PH. D in physics at Harvard University. The machine was built by IBM engineers in Endicott, New York. It was shipped to Harvard University in February 1944.
The original name of the Harvard Mark I computer was the IBM Automatic Sequence Controlled Calculator. Its acronym is (ASCC). The Harvard Mark I was an electromechanical computer. In actuality the computing mechanism in the majority of the computers built in the year 1940 was electronic. The numeral system in this computer is in the decimal format. During this time the numeral system in most of these computers were binary.
The numeral system of binary is quite easy to comprehend. Binary is two numbers that represent any number. This means in binary code there is only 0 and 1. For instance the number 5 is 101. Binary code is read from right to left. The first spot is one. For every spot afterwards the number doubles. For instance it goes 1,2,4,8,16,32,64,128 and it goes on. This means 5 = 101 because there is a number one in the four spot and another one in the one spot. You add the four and one spot to get 5. Any number can be turned into binary code.
There are many interesting facts about the Harvard Mark I. This computer was composed of switches, relays, rotating shafts and clutches. The machine used 765,000 components. Within this computer there were 500 miles of wire. The length of the Harvard Mark I was 51 feet. Its height was 8 feet. The length of the computer was 2 feet. Its weight was about 10,000 pounds. The calculating units were run by a 50 foot shaft run by a 5 horsepower electric motor. There were 3 million connections in this computer. Norman Bel Geddes was the designer of this contraption.
The massive calculator had many functions that are outdated today. It was able to do three additions or subtractions in a second. Multiplication equations took six seconds to resolve. A division equation took 15.3 seconds. A logarithm or trigonometric function took over one minute to resolve. The computer read the instructions through a punched paper tape. The Harvard Mark I was able to use many digits to solve equations. Interestingly, the task of this computer was to do computations for the U.S. Navy Bureau of Ships during World War II.
The future of the Harvard Mark I had many events. After the Harvard Mark I, the Harvard Mark II, III and IV were created. Howard Aiken was also responsible for these creations. The Mark II and III went to the naval base in Dahlgren, Virginia. The Mark IV was constructed for the U.S. Air Force. The Harvard Mark I remained at Harvard. This computer became disassembled. Portions of the Mark I do remain at Harvard. These portions form part of the Harvard collection of Historical Scientific Instruments.
World War II was a significant war. I decided not to write about World War II technology specifically because I believe that writing about the beginning of computers is more important for my topic. This war did cause the creation of innovative technology. These creations include the nuclear weapon created by the Americans and the synthetic rubber. The Japanese needed synthetic rubber because they were not able to obtain rubber. The United States supplied Japan the rubber until the trading stopped due to war. When countries are engaged in war they are able to use their creative skills to innovate in the field of technology.
The Harvard Mark I is a computer that I enjoyed learning about. First off this computer or massive calculator amazed Americans. Just four years prior to this, massive calculations had to be done manually. This boosted the morale of the American mathematicians. This is because the earliest computer the Zuse Z3was created by Germany in the year 1941. For the purpose of the war this was an advantage to the Nazi side. This government was able to use this computer and be able to show their strength.
Reading about this contraption made me astonished about the evolution of computers. Just 70 years ago the first computer was invented. Its only purpose was to do computations. This computer would have not fit in a regular size living room. 40 years later the personal computer was invented. These computers though used paper just like the punch cards to use its information. During this decade, the 80’s, the floppy disk, speakers, mouse, printer and the keyboard were introduced. During this time people were amazed because they were used to using a typewriter. Ten years later the laptop was introduced in the commercial market. This was a breakthrough because computers were now portable enough to fit in a book bag. In our lifetime we have already seen changes made towards computers. Net books were introduced five years ago. These mini laptops are about the size of a textbook, but with half the weight. I also consider the Ipod and I pad to be a breakthrough in the field of computers. I pods and I pads do most of the functions of a computer and they are less than an inch thick. Compared to the Harvard Mark I, the Ipod is a miracle.
My appreciation for computers is immense. There are people in the world today that have seen the whole evolution of computers. We are now getting to a point where progress to computers cannot be much innovating anymore. If Howard Aiken would have been alive today, he would have been proud to see the enormous progress that has been made to computers. Those calculations that needed to get done in the 40’s can now be done on a program on a laptop.
