How much do you know about Albert Einstein? Albert Einstein, born on March 14, 1579 in Germany, was a great scientist in the world. He was strange because he hated haircuts and new clothes. He believed in peace. All his life, he hated war. However, his most famous idea, E=mc2, helped create the world's most dangerous weapon . Many people think he was the smartest person in the world. But Einstein said that _ What did he like? Einstein liked learning sailing . He sailed in small boats all his life. He once joked, "Sailing is the sport that takes the least energy!" When Einstein was a child, his mother made him take violin lessons. At first, he didn't like the violin. But then he learned to love music and became a good violinist. Later, he said, "Love is the best teacher." Why is the sky blue? In 1910, Einstein asked a question which many children often ask, "Why is the sky blue?" After his careful research, he answered the question like this: "It's because light is made up of many colors including blue. When light travels to Earth, gas particles spread the blue light all over the sky." His answer is true in physics. What are the answers to this following set of questions: 1.

Chicago ( or ), officially the City of Chicago, is the third-most populous city in the United States. With over 2.7million residents, it is also the most populous city in both the state of Illinois and the Midwestern United States. It is the county seat of Cook County. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10 million people and is the third-largest in the U.S. Chicago has often been called a global architecture capital. Chicago is considered one of the most important business centers in the world.

Chicago was incorporated as a city in 1837, near a portage between the Great Lakes and the Mississippi River watershed, and grew rapidly in the mid-nineteenth century. After the Great Chicago Fire of 1871, which razed several square miles and left more than 100,000 homeless, the city made a concerted effort to rebuild on the damage. The construction boom accelerated population growth throughout the following decades, leading Chicago to become among the five largest cities in the world by 1900. During this period Chicago made noted contributions to urban planning and zoning standards, new construction styles (including the Chicago School of architecture), the development of the City Beautiful Movement, and the eventual creation of the steel-framed skyscraper. What are the answers to this following set of questions: 1. How many people live in Chicago?
2. What is Chicagoland?
3. How many people live there?
4. What was early Chicago near?
5. What water bodies did the portage connect?
6. How many people had nowhere to live after the fire?
7. How many actual houses were ruined?
8. True or False: The population size never recovered from the disaster.
9. What movement started in Chicago?
10. What tall structure was invented there?
11. True or False: The Baroque school of architecture started there.

"A computer program is a collection of instructions that performs a specific task when executed by a computer". A computer requires programs to function and typically executes the program's instructions in a central processing unit.

A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler can derive machine codea form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter.

A part of a computer program that performs a well-defined task is known as an algorithm. A collection of computer programs, libraries, and related data are referred to as software. Computer programs may be categorized along functional lines, such as application software or system software.

The earliest programmable machines preceded the invention of the digital computer. In 1801, Joseph-Marie Jacquard devised a loom that would weave a pattern by following a series of perforated cards. Patterns could be woven and repeated by arranging the cards.

In 1837, Charles Babbage was inspired by Jacquard's loom to attempt to build the Analytical Engine. The names of the components of the calculating device were borrowed from the textile industry. In the textile industry, yarn was brought from the store to be milled. The device would have had a "store"memory to hold 1,000 numbers of 40 decimal digits each. Numbers from the "store" would then have then been transferred to the "mill" (analogous to the CPU of a modern machine), for processing. It was programmed using two sets of perforated cardsone to direct the operation and the other for the input variables. What are the answers to this following set of questions: 1. What is a part of a computer program that performs a defined task?
