Metro police chief Steve Anderson's letter to Judge Higgins.
It is not a biography, as you would seemingly assume, it is more like a guidebook. And Why? The book is predetermined for all those individuals who believe that they can accomplish something exceptional. Despite being a technophile, he is also a philanthropist, programmer, writer and an electronics engineer. In , Steve single-handedly managed to develop Apple I, and one year later he also designed Apple II — first ever microcomputer. In , Upside Magazine placed her among the most influential individuals in technology. Steve Wozniak declared that all of the merits go to his father, Jerry.
But this kid I told, he said, "Oh, you know, there's this guy down the street, Mr. Giles, and he's teaching a class on this. Are you in it? I remember being astounded. It turned out that on Wednesday nights Mr. Gileswho actually was a ham radio operatorhad these classes I could take. I learned Morse code there, I learned some of the electronics calculations I needed, I learned what fre quencies ham radio operators were allowed to use.
Basically, I got to learn all the stuff that was going to be on the test you had to take to be a licensed ham radio operator. My dad saw what I was doing, and he got his license with me. We both took the test and passed when I was in the sixth grade. And for that Christ mas, I got kits to build a Hallicrafters transmitter and a Hallicrafters receiver.
In today's money, it probably cost a couple thousand dollars.
That's a lot of money to spend on a sixth grader. And building the radio transmitter and receiver was a lot of work!
You had to unpackage hundreds of parts. I had to learn to solder for that, too. In fact, I soldered together the whole 30 A Little More About the Transistor The transistor will likely go down as one of the greatest inven tions in modern history, ranking right up there with the car, the telephone, and Gutenberg's printing press. William Shockley and his team at Bell Labs invented the transistor in Put most simply, a transistor is a tiny electronic device to con trol the flow of electricity.
But a transistor is more than that. It hastwo key abilities: the first isto amplify an electric signal, and the other isto switch on or off 1 or 0 , letting currentthrough or blocking it as necessary.
Transistors are in practically allmodern electronics these days, from musical birthday cards, to your car, to your personal com puter. Since and this is what has made the computer rev olution possibleit has become cheaper and cheaper to pack more transistors onto a computer chip every year. He said that everyyearmanufacturing would get so good that double the number of transistors would be able to fit on a chip for the same price.
A simple logic gate comprises about twenty transistors, com pared to an advanced computer chip in a modern circa computer, which can include as many as a billion transistors. We also had to go up on the roof and string antennas of a certain length, to be right for the signals I needed. This was the beginning of learning the kinds of things I would need later to design and assemble computer boards like the one that later became the Apple I.
I loved my transmitter and receiver. They were such standouts in ham radio qualitythese days, I even see these models fea tured in radio museums and collectors' magazines. I didn't really get into talking to the other ham radio operatorsthey were so The Logic Game much older than me and we really didn't have anything except for the ham radios in common. So after building it, I have to admit the whole thing got a little boring.
But this experience was a major one. For one thing, I'm fairly sure I was one of the youngest ham radio operators in the country. That was huge for me. But even more importantly, I learned all about the process of getting a ham radio licensewhat I needed to know, what I needed to build the equipmentand then I built the radio. It gave me a lot of confi dence for doing all kinds of other projects later on.
So my dad ended up being a key influence here, too. I mean, he even got his ham radio license with mestudying with me and taking and passing the test! The thing is, he never really tried to lead me in any direction or push me into electrical engineer ing. But whenever I got interested in something he was right there, always ready to show me on his blackboard how something worked.
He was always ready to teach me something. My mom really pushed me along, too. In the third grade, when I started doing math flash cards at school, my mom prac ticed multiplication with me the night before we'd have to do them in school. And as a result, in school I was the only boy who could beat the girls at them. I remember a teacher said, "Wow, that's incredible. I never had a boy before who could beat the girls at flash cards.
Girls always seemed to get better grades than boys, I thought. And then I thought: Whoa. My gosh, I'm good at somethingmath and I'm going to work harder at it. And I worked harder and harder to try to always be the best, to try to always be ahead. That's what really put me ahead at such a young age, this drive to keep my lead. I had a teacher in both the fourth and fifth grades, Miss Skrak, who really praised my science projects, like I was the smartest kid in the class because I knew science so well.
As you'd predict, 32 I accelerated even more later on. In sixth grade I was doing elec tronicsprojectsmostkids neverfigure out howto do evenin high school-level electronics. SoI wasveryluckywith allmy teachers, especiallyMiss Skrak. She came along at just the right time in my life. At about this time, there was another lucky accident. I found this article about computers in one of the old engineering jour nals my dad had hanging around.
Back then, back in , writ ing about computers wasn't common at all. It was designed to calculate bomb trajectories for the military during World War II. So it was designed back in the s.
This journal had all kinds of pictures of huge computers and articles describing them. These computers were unlike anything I'd ever seen. One picture showed a big round tube that looked like a TV tube. And the article explained that the round tube was where these huge computers stored data. It used phosphor lights and then it could read if the phosphors lights were on or offjust like the digits 1 and 0 on today's computers can be inter preted as On or Offand then it could reset them quickly.
This, the article explained, was actually a way to store data, and I was just intrigued by that idea. I was about eleven years old at the time. Suddenly I realized that some incredible things were just start ing to happen with computers at these very early stages.
Of course, they were nowhere near the point of making computers affordable or usable for the world. They weren't even talking about a point where anyone could buy a computer and put it in your house and learn how to use it yourself. I thought that would be just the best thing, and that was the dreamThe Dream, I The Logic Game have to put that in capital lettersbecause it was the single force that drove me for years afterward.
How to make The Dream come true. I thought about that constantly. There were so many incredible things happening with com puters at that time, and I would never have known about them if I hadn't been too shy to do anything but read magazines at my house. The amazing thing was that at this early stage in my life, I'd managed to find this journal Dad had with this stuff in it.
This was a magazine most people were never supposed to see or even be interested in because it was targeted to high-level govern ment engineers. After that, I was addicted. I started reading and rereading this journal and others my dad had. I remember one day finding an article on Boolean algebra. That's the type of mathematics com puters use.
And that's how logic became the heart of my existence, there in the fifth grade. In logic, for instance, you might ask if a word starts and ends with a vowel.
Well, then the formula would be an ANDthere's a vowel at the beginning and a vowel at the end. That's AND in Boolean algebra. But what about a word that starts with a vowel but doesn't end with one, or the other way around, but not both?
That's an OR statement in Boolean algebra. And in this journal they had diagrams of AND gates and OR gates and I copied them, learning to draw them the standard way. For instance, a half-moon shape with a dot in the middle rep resents an AND gate.
If it has a plus sign in the middle instead of a dot, it's an OR gate. Then I learned how to draw a picture that represented an inverterit's a triangle pointing to the right with a little tiny circle at the very end of its tip. What's funny is, I use these very same symbols when I design electronics to this day, 34 and I learned all this in my room with these journals in front of me on my bed in fifth grade. Here's what was amazing to me back then. I thought to myself: Hey, at my current level of fifth-grade math, I am able to learn the math used by a computerDe Morgan's Theorem, Boolean alge bra.
I mean, anyone could learn Boolean algebra and they wouldn't even need a higher level of math than I already had in fifth grade. Computers were kind of simple, I discovered. And that blew me away. Computerswhich in my opinion were the most incredible things in the world, the most advanced technology there was, way above the head, above the understanding, of almost everyone were so simple a fifth grader like me could understand them!
I loved that. I decided then that I wanted to do logic and computers for fun. I wasn't sure if that was even possible. To say you wanted to play with computers in those days, well, that was so remote. It was like saying you wanted to be an astro naut. It was ; there weren't even real astronauts yet! The odds of being one seemed really slim. But logic was different.
I could see that it just came so easily for me. And it always would. So that's how computers became the heart of my life straight through. As a matter of fact, computer logic was something I eventually became better at than probably any other human alive. I can't be sure of that, of course. Maybe there were really highup people in colleges who were as good at applying De Morgan's Theorem in their heads.
But by the time I designed the first Apple computer, logic was my life. I know it sounds unbelievable, but I just loved logic and everything about it, even back then.
I was in elementary school and junior high at a time when sci ence projects were coolwhen you weren't strange if you did one, and you got celebrated if you won an award. So I got cele brated a lot. My science fair projects are some of the things I am still proudest of.
We're talking third, fourth, fifth, sixth, and The Logic Game eighth grades here. For some reason, I didn't enter a project in the seventh grade. And these projects were hard, harder than kids many grades ahead of me could ever pull off, and I knew it even then. I put some science projects together that, for that audience of kids and judges, just blew their minds.
The science fairs gave me the feeling of what I was and could be in the world, just by entering something good in a science fair. The teachers recognized something different about me immedi ately; some of them even started calling me Science Whiz because I had all these great projects in the science fairs.
And probably as a result of that, by sixth grade I was doing electron ics projects few people in high school could even understand yet. Those kinds of acknowledgments and those kinds of achieve ments made me want to keep working at those things until they would be my things in the world. My first science competition was in third grade, and I won.
But the project was pretty simple, really. Basically I put together this little contraption with a light and a couple of batteries and a lit tle wireall mounted on a piece of wood. It was a working flash light!
A lot of people were surprised by that, and I won. No big deal, it turns out, because I felt inside it wasn't really that impres sive, and I knew I would do even better the next time. It was in the fourth grade that I did the first project that really taught me about things I would need laterphysics, electronics, and the project materials.
It was an experiment to see what would happen if you dipped these two carbon rods into any liq uid of your choice. The carbon rods were connected by a wire to a lightbulb and an AC plug. By dipping the carbon rods into the liquid, the liquid in effect became one of the "wires. If the light- bulb glowed, brightly or dimly, you could see how well the liquid could conduct electricity.
I used every liquid I could get my hands onwater, Coca-Cola, iced tea, juice, beer. Which liquid conducts electricity best? The answer turned out to be salt water. This is an extremely impor tant thing to know if you want to understand, for instance, hydroelectric machinery or even just plain old batteries.
But the next experiment, man, that was a big one. What I did was build this giant real-life electronic model representing what each of the ninety-two atoms in the periodic table looks like in terms of its electrons.
Download PDF. When Stephen Gary Wozniak was born , computers already existed, but not nearly the way you know them today. To be passionate about computers meant to be passionate first and foremost about electronics — and Steve grew up in the exact right environment for that.
His father Francis worked at an electronics company, Electronic Data Systems in Los Angeles, at the time, and would sometimes take him to work, where he could play with various electronic parts. Woz also adopted most of the values that would shape his later way in life during this time, such as honesty, fairness, kindness and a sense of humor.
Winning science competition after science competition in high school, pursuing a degree in engineering in college was only the next logical step for him.
He transferred in , but without the funds to build his own computer, he kept teaching himself by re-designing existing computers to be more efficient on paper, until he finally had enough money and parts while taking a gap year, working at Tenet, a small computer company.
Eventually, he managed to build his first computing machine, the Cream Soda Computer , which was really just a circuit board, but an actual, usable computer nonetheless. People often wanted Woz to move into Apple management, but he always refused.
He was an engineer at heart, and that meant he wanted to keep engineering things. He stayed honest along the way, even offering his bosses at HP rights to the first Apple prototype, and only moving on with Apple once they rejected them — a move that saved Apple millions of dollars in potential lawsuits later on.
The people who build empires on being good. Woz is one of those people. He always has and always will be, the good soul of Apple.
