Biography of Steve Wozniak, Apple Computer Co-Founder

Biography of Steve Wozniak, Apple Computer Co-Founder Steve Wozniak (born Stephan Gary  Wozniak; August 11, 1950) is the co-founder of Apple Computer and is credited with being the main designer of the first Apples. A noted philanthropist who helped found the Electronic Frontier Foundation, Wozniak was the founding sponsor of the Tech Museum, the Silicon Valley Ballet, and the Children’s Discovery Museum of San Jose. Fast Facts: Steve Wozniak Known For: Apple Computer co-founder with Steve Jobs and Ronald Wayne and the main designer of the first Apple computersBorn: August 11, 1950 in Los Gatos, CaliforniaEducation: Attended  De Anza College and the University of California, Berkeley; awarded a degree from Berkeley in 1986Spouse(s): Alice Robertson (m. 1976–1980), Candice Clark (m. 1981–1987), Suzanne Mulkern (m. 1990–2004), Janet Hill (m. 2008)Foundations Started: Apple Computer, Inc., Electronic Freedom FrontierAwards and Honors: National Medal of Technology, Heinz Award for Technology, The Economy and Employment, Inventors Hall of Fame inducteeChildren: 3 Early Life Wozniak (known as the Woz) was born on August 11, 1950, in Los Gatos, California, and grew up in the Santa Clara Valley, now known as Silicon Valley. Wozniaks father was an engineer for Lockheed and always inspired his sons curiosity for learning with a few science fair projects. He gave Steve his first crystal set at the age of 6. Wozniak got his ham radio license in the sixth grade and built an adder/subtractor machine to calculate binary arithmetic in the eighth grade. As a young man, Wozniak was a bit of a prankster/genius and wrote his first programs in his own version of FORTRAN at the University of Colorado but was put on probation for computer abuse- essentially, he spent the computing budget for the whole class five times over. He designed his first computer called the Cream Soda Computer, which was comparable to the Altair, by the time he was 18. He began courses at the University of California, Berkeley, where he was introduced to Steve Jobs by a mutual friend. Jobs, still in high school and four years younger, would become Wozniaks best friend and business partner. Their first project together was the Blue Box, which allowed the user to make long-distance phone calls for free; Wozniak himself thinks he should be remembered by posterity for running the first dial-a-joke service in the San Francisco Bay area. Early Career and Research In 1973, Wozniak dropped out of college to begin designing calculators at Hewlett Packard, but he continued to work on side projects. One of those projects would become the Apple-I. Wozniak built the first design for the Apple-I in his office at Hewlett Packard; he worked closely with an informal users group known as the Homebrew Computer Club, sharing schematics and giving away his code. Jobs had no input into the original build but was the visionary of the project, discussing enhancements and coming up with some investment money. They signed partnership papers on April 1, 1976, and began selling the Apple-I at $666 per computer. That same year, Wozniak began to design the Apple-II. In 1977, the Apple-II was revealed to the public at the West Coast Computer Faire. It was an astonishing success, even at the very steep price of $1,298, selling 100,000 units in three years. Jobs opened their first business office at Cupertino and Wozniak finally quit his job at H-P.  Wozniak has been credited by everyone, including Steve Jobs, as the main designer on the Apple I and Apple II. The Apple II was the first commercially successful line of personal computers, featuring a central processing unit, a keyboard, color graphics, and a floppy disk drive. Leaving Apple On February 7, 1981, Wozniak crashed his single-engine aircraft in Scotts Valley, California, an event that caused Wozniak to temporarily lose his memory. On a deeper level, it certainly changed his life. After the accident, Wozniak left Apple and returned to Berkeley to finish his degree in electrical engineering/computer science- but dropped out again because he found the curriculum confining. He was awarded a bachelors degree anyway in 1986 and has since been awarded numerous degrees from institutions such as Kettering and Michigan State University. Wozniak did return to work for Apple for a brief period between 1983 and 1985. During that time, he greatly influenced the design of the Apple Macintosh computer, the first successful home computer with a mouse-driven graphical interface. He still has a ceremonial role in the company, saying, I keep a tiny residual salary to this day because thats where my loyalty should be forever. He founded the UNUSON (Unite Us In Song) corporation and put on two rock festivals. The enterprise lost money. In 1990, he joined Mitchell Kapor in establishing the Electronic Frontier Foundation,  the leading nonprofit organization defending civil liberties in the digital world. In 1987, he created the first universal remote. In 2007, Wozniak published his autobiography, iWoz: From Computer Geek to Cult Icon, which was on the best seller list of The New York Times. Between 2009 and 2014, he was hired as chief scientist for Fusion-io, Inc., a computer hardware and software company that was acquired by SanDisk Corporation. He was later the chief scientist at the data virtualization company Primary Data, which shut down in 2018. Marriage and Family Steve Wozniak has been married four times, to Alice Robertson (m. 1976–1980), Candice Clark (m. 1981–1987), Suzanne Mulkern (m. 1990–2004), and currently Janet Hill (m. 2008). He has three children, all from his marriage with Candice Clark. Awards Wozniak was awarded the National Medal of Technology by President Ronald Reagan in 1985, the highest honor bestowed on America’s leading innovators. In 2000, he was inducted into the Inventors Hall of Fame and was awarded the prestigious Heinz Award for Technology, The Economy and Employment for â€Å"single-handedly designing the first personal computer and for then redirecting his lifelong passion for mathematics and electronics toward lighting the fires of excitement for education in grade school students and their teachers.

Research Methodologies Applied To Evaluate The Impact Of Stimulant Assignment

Research Methodologies Applied To Evaluate The Impact Of Stimulant Energy Drink - Assignment Example Methodology Collection Of Data The first thing for any study is the process of data collection and the method of sampling. Data is collected on the basis of sampling which can be randomized, or purposive with respect to the variable that has to be analyzed. Randomized data means each individual will have equal probability to be included in the sample. Purposive data is considered by some criteria fixed by the experimenter (effects of a drug on diabetic patients).Sampling makes sure that the results are based on non biased assumptions and simply random sampling reduces the chance of bias. So in this study we will fix inclusion criteria with a purposive sampling- that means people who use computers whether desktops and laptops will be included and the others in the population will not be included- thus our purposive sampling will narrow it to population of computer users. The exclusion criteria would be non computer users and having vision problems other than technology related. Data will be collected through a set of questionnaire method:- a. Energy severity score: Rate your self energy on a scale of 1 to 10( more energy feeling more score) b. Rate your sleep scale from 1-1 0 ( more score more awake) We would see then whether our distribution obtained is symmetrical or asymmetrical and conform to normal distribution and whether undue weightage has been given to extreme values during data collection. Collected data can have a symmetrical representation and in that case mean, median and mode will be the same for a particular variable and when these value changes it is called asymmetrical and this measure is called skewness, On the other hand there can be incidences such the data is collected more on the upper and lower sides of a variable(tails) it will be called leptokurtic data and if the middle values of a variable are collected it is called platykurtic data. In the former the distribution looks pointed and in later it has a plateau shaped. Ideally if a data is ideally collected then the curve should look mesokurtic with frequency of the scores evenly distributed at upper and lower and middle limits. This is called a normal distribution. The normal distribution has a unit area of one and this is helpful to measure testing of hypothesis.(Chance,2005). Thus the need for data representation becomes important Analysis of Data Testing of Hypothesis: We will take the mean scores of sleepiness and energy in both the groups and go for a testing of hypothesis Data can be analyzed for statistical significance based on the normal distribution. This means if the computed probability value or p value as measured from t test or Anova is
