Memorable quotes of Steve Jobs.

1. “I was worth over $1,000,000 when I was 23, and over $10,000,000 when I was 24, and over $100,000,000 when I was 25, and it wasn’t that important because I never did it for the money.”
2. “Being the richest man in the cemetery doesn’t matter to me … Going to bed at night saying we’ve done something wonderful… that’s what matters to me.” – Wikiquote, as quoted in The Wall Street Journal (Summer 1993).
3. “Unfortunately, people are not rebelling against Microsoft. They don’t know any better.” – Wikiquote, Interview in Rolling Stone magazine, no. 684 (16 June 1994)
4. “The only problem with Microsoft is they just have no taste. They have absolutely no taste. And I don’t mean that in a small way, I mean that in a big way, in the sense that they don’t think of original ideas, and they don’t bring much culture into their products.” – YouTube
5. “It’s really hard to design products by focus groups. A lot of times, people don’t know what they want until you show it to them.” – Businessweek, 1998
6. “I feel like somebody just punched me in the stomach and knocked all my wind out. I’m only 30 years old and I want to have a chance to continue creating things. I know I’ve got at least one more great computer in me. And Apple is not going to give me a chance to do that.” – Playboy, 1987
7. “I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.” - Steve Jobs’ Stanford Commencement Address
8. “My job is not to be easy on people. My jobs is to take these great people we have and to push them and make them even better.” – All About Steve Jobs
9. “I’m the only person I know that’s lost a quarter of a billion dollars in one year…. It’s very character-building.” – Wikiquote, as quoted in Apple Confidential 2.0: The Definitive History of the World’s Most Colorful Company (2004) by Owen W. Linzmayer
10. “The cure for Apple is not cost-cutting. The cure for Apple is to innovate its way out of its current predicament.” - As quoted in Apple Confidential 2.0: The Definitive History of the World’s Most Colorful Company (2004) by Owen W. Linzmayer

Infinity symbol in physics

In physics, approximations of real amounts can be used for continuous dimensions and natural amounts can be used for discrete dimensions. Therefore, it is assumed by physicists that no measurable quantity might have an infinite value, for example if you take an infinite value within an extended real number system, or by needing the counting of thousands of occasions. It's for instance presumed impossible for just about any body to possess infinite mass or infinite energy. Concepts of infinite items like an infinite plane wave exist, but you will find no experimental way to generate them.

Theoretical programs of physical infinity

The concept of declining infinite values for measurable amounts doesn't originate from a priori or ideological motivations, but instead from more methodological and practical motivations.[citation needed] Among the needs associated with a physical and scientific theory would be to give functional formulas that match or at best approximate reality. For example if any object of infinite gravitational mass were to exist, any using the formula to calculate the gravitational pressure would result in an infinite result, which may constitute no benefit because the result could be always exactly the same no matter the positioning and also the mass from the other object. The formula could be helpful neither to compute the pressure between two objects of finite mass nor to compute their motions. If the infinite mass object were to exist, any object of finite mass could be attracted with infinite pressure (and therefore acceleration) through the infinite mass object, which isn't what we should can watch the truth is. Sometimes infinite consequence of an actual quantity may imply that the idea getting used to compute the end result might be approaching the stage where it fails. This might help to indicate the restrictions of the theory.

This perspective does not necessarily mean that infinity can't be utilized in physics. For convenience's sake, information, equations, ideas and approximations frequently use infinite series, unbounded functions, etc., and could involve infinite amounts. Physicists however require the finish result be physically significant. In quantum area theory infinities arise which have to be construed in a way regarding result in a physically significant result, a procedure known as renormalization.

However, you will find some theoretical conditions in which the finish outcome is infinity. An example may be the singularity within the description of black holes. Some solutions from the equations from the general theory of relativity permit finite mass distributions of zero size, and therefore infinite density. It is really an example of what's known as a mathematical singularity, or perhaps a point in which a physical theory stops working. This doesn't always imply that physical infinities exist it might mean simply the theory is not capable of explaining the problem correctly. Two other good examples exist in inverse-square pressure laws and regulations from the gravitational pressure equation of Newtonian gravity and Coulomb's law of electrostatics. At r= these equations evaluate to infinities.

Cosmology

In ancient cosmologies, heaven was regarded as a good dome, or firmament. In 1584, Bruno suggested an unbounded world in Around the Infinite World and Mobile phone industry's: "Countless suns exist countless earths center around these suns inside a manner like the way the seven planets center around our sun. Living creatures inhabit these mobile phone industry's."

Cosmologists have lengthy searched for to uncover whether infinity is available within our physical world: Exist thousands of stars? Does the world have infinite volume? Does space "continue forever"? It is really an open question of cosmology. Observe that the question to be infinite is realistically outside of the question of getting limitations. The 2-dimensional top of the Earth, for instance, is finite, yet doesn't have edge. By travelling inside a straight line you will eventually go back to the precise place one began from. The world, a minimum of in principle, might have the identical topology if a person travelled inside a straight line with the world possibly you might eventually revisit a person's beginning point.

If, however, the world weren't curved just like a sphere but were built with a flat topology, it may be both unbounded and infinite. The curvature from the world could be measured through multipole moments within the spectrum from the cosmic background radiation. As up to now, research into the radiation designs recorded through the WMAP spacecraft hints the world includes a flat topology. This is in line with an infinite physical world. The Planck spacecraft released last year is anticipated to record the cosmic background radiation with 10 occasions greater precision, and can give more understanding of the question of if the world is infinite or otherwise.
