1When did Charles Babbage design the world’s first true computer’? 2 Who helped him to write a programme for his invention? 3 Whose daughter was Ada Lovelace? 4 Did Babbage and Lovelace finish their work? 5 What source of power did Babbage use for the Analytical Engine? Why? 6 Who did he get the idea for his input device from? Did you know? Prior to 1980, Webster’s Dictionary defined the word ‘computer’ as a person who computes, typically with a slide rule! 5 Complete the sentences with the proper names of computer pioneers. Then choose the scientist you like most and prepare a short talk about their inventions. Semyon Korsakov Blaise Pascal Charles Babbage Ada Lovelace Gottfried Leibniz Wilhelm Schickard 1 … was a genius of the first order – a mathematician and professor, an engineer and inventor, a politician, a writer, a founder of scientific organizations and an expert on industry. His pioneering book on the Economy of Machinery and Manufactures was cited repeatedly by Marx in Capital. He was a human dynamo who needed only five or six hours to sleep a day and who was driven by millenarian version of man and machine that brought him within a hair’s breadth of the invention of the greatest of all machines – the Computer. 2 The English mathematician … wrote hypothetical programs for the Analytical Engine, saying, “A new, a vast and a powerful language is developed for future use of analysis”. For that work …is often considered the world’s first programmer. In 1980, the US Department of Defense settled on (in honour of ….) the name … for a new standardized computer language. But some scientists think that… was Babbage’s fairy lady – interpreter, adviser, collaborator and only supported Charles Babbage financially, intellectually and emotionally. As such her achievement was certainly remarkable.
3 …was a very competent mathematician. He became intrigued with the possibility of using machinery to enhance natural intelligence and later he invented several devices which he called machines for the comparison of ideas. Just like Babbage, … could see the perspective of the suggested mechanization of thinking and just like Babbage, intended to use punched cards as a memory holder. Aiming to create an auxiliary amplifier for natural intelligence, … invented five devices. He announced his new devices in September 1832. Later the same year, he presented his ideas to the Imperial Academy of Science in St. Petersburg, but their experts rejected his application, failing to see the potential of mechanizing searches through large stores of information. The commission, led by the famous mathematician M. Ostrogradski, even made an ironical note: “Mr. … wasted his intelligence in order to teach other people to live without intelligence.” 4 The French most celebrated mathematician … was also a famous physicist and religious philosopher. In 1642, at the age of 18, …. constructed a calculating device, the Pascaline, to help his father in his tax computations. The machine was regarded by …’s contemporaries as his main claim to fame. It was the first digital calculator since it operated by counting integers. In fact the machine could only add, because subtractions were performed using complement technique.
5 The great German mathematician … was one of the first men who dreamed for a logical (thinking) device. While working on adding automatic multiplication and division to Pascal’s calculator. … created the first mechanical calculator, suitable not only for a addition and subtraction, but for multiplication also. It was the first calculator that could perform all four arithmetic operations.
6 The German astronomer, mathematician and cartographer … created an adding machine preceding that of Pascal. He called it a Calculating Clock, the first form of the mechanical calculator that we use today. Unfortunately, the machine designed by… around 1623, didn’t manage to survive to the present day. Only 3 documents about the machine have been found till now. But modern engineers have been able to reproduce it from details in his letters.

Did you know? A supercomputer was used to mimic brain but even with its 83 000 processors it could mimic just 1% of one second of human activity and it took 40 minutes to do so.
44A Read the article and suggest the title. What do you understand by ‘intelligence’? There's more to intelligence than processing speed. While a supercomputer like the Sequoia can analyze problems and reach a solution faster than humans, it can't adapt and learn the way humans can. Our brains are capable of analyzing new and unfamiliar situations in a way that computers can't. We can draw upon our past experiences and make inferences about the new situation. We can experiment with different approaches until we find the best way to move forward. Computers aren't capable of doing that -- you have to tell a computer what to do. Humans are also very good at recognizing patterns. While we're making progress in machine pattern recognition, it's mostly on a superficial level. For example, some digital cameras can recognize specific faces and automatically tag photos of those people as you take pictures. But humans can recognize complex patterns and adapt to them -- computers still have trouble doing that. Could computer scientists build a machine that simulates the way humans think? It's not as easy as it sounds. The human brain is incredibly complex. We still don't have a full understanding of how the brain works. Without this understanding, it's challenging to create a meaningful simulation of the brain. One of the features computers would need to be more intelligent than humans is the ability to draw conclusions from observations. In a study published in 2009, computer engineers at Cornell University designed a program that could do this on a limited scale. The program gave the computer a basic set of tools it could use to observe and analyze the movements of a pendulum Using this foundation, the software was able to extrapolate basic laws of physics from the pendulum's motions. It took about a day for the computer to arrive at the same conclusions it took humans thousands of years to grasp. While the Cornell project was a remarkable achievement in computer engineering, we're still years away from computers that can make conclusions from general observations. The Cornell software gave the computer the tools it needed to draw conclusions -- the computer was unable to create or refine these tools for itself. As long as computers rely on sets of pre-installed instructions to perform tasks, they can't be said to be more intelligent than humans. Even IBM's Watson can only respond to input -- it can't spontaneously pull up information or think in the way we humans do. Only when computers can adapt and perform tasks outside their initial programming will they be truly intelligent. Until that time, computers are just very sophisticated calculator. Hundreds of computer scientists are trying to solve this crucial problem. Some are attempting to design computers that can mimic human thought -- a tricky situation considering we still don't have a complete understanding of how we think. Other computer scientists prefer to design systems that don't use the brain as a model. Futurists like Dr. Ray Kurzweil predict that it's just a matter of time before we develop a computer system capable of being self-aware. After that, we may see computers capable of recursive self-improvement. That means computers will be able to analyze their own capabilities and make adjustments to improve performance. But creating a self-aware computer system is beyond our capabilities right now. It may not even be possible. While we continue to gain understanding in the fields of biology and computer science, we may encounter a fundamental obstacle before we can ever create a self-aware machine. Alternatively, we may come to a point where human and machine intelligence merge, leaving the entire question moot
