The Trouble With Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next
Lee Smolin Manufacturer: Houghton Mifflin ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 0618551050 |
Book Description
In this groundbreaking book, the renowned theoretical physicist Lee Smolin argues that physics—the basis for all other science—has lost its way. The problem is string theory, an ambitious attempt to formulate "a theory of everything" that explains all the forces and particles of nature and how the universe came to be. With its exotic new particles and parallel universes, string theory has captured the public"s imagination and seduced many physicists. But as Smolin reveals, there"s a deep flaw in the theory: no part of it has been proven, and no one knows how to prove it. As a scientific theory, it has been a colossal failure. And because it has soaked up the lion's share of funding, attracted some of the best minds, and penalized young physicists for pursuing other avenues, it is dragging the rest of physics down with it. With clarity, passion, and authority, Smolin charts the rise and fall of string theory and takes a fascinating look at what will replace it. A group of young theorists has begun to develop exciting new ideas that are, unlike string theory, testable. Smolin tells us who and what to watch for in the coming years and how we can find the next Einstein. This is a wake-up call, and Lee Smolin—a former string theorist himself— is the perfect person to deliver it.Customer Reviews:

The End of Time: The Next Revolution in Physics
Julian Barbour Manufacturer: Oxford University Press, USA ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0195145925 |
Book Description
Richard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist. In this highly provocative volume, Barbour presents the basic evidence for a timeless universe, and shows why we still experience the world as intensely temporal. It is a book that strikes at the heart of modern physics. It casts doubt on Einstein's greatest contribution, the spacetime continuum, but also points to the solution of one of the great paradoxes of modern science, the chasm between classical and quantum physics. Indeed, Barbour argues that the holy grail of physicists--the unification of Einstein's general relativity with quantum mechanics--may well spell the end of time. Barbour writes with remarkable clarity as he ranges from the ancient philosophers Heraclitus and Parmenides, through the giants of science Galileo, Newton, and Einstein, to the work of the contemporary physicists John Wheeler, Roger Penrose, and Steven Hawking. Along the way he treats us to enticing glimpses of some of the mysteries of the universe, and presents intriguing ideas about multiple worlds, time travel, immortality, and, above all, the illusion of motion. The End of Time is a vibrantly written and revolutionary book. It turns our understanding of reality inside-out.Customer Reviews:

An All Around Guide to Cutting.......2000-04-22
When Barbara presents information on reading cattle and working the herd, she excels. The reader will appreciate how she breaks down each step of a cut and correlates those steps with what the rider should be doing to effectively ride his or her horse. She could have written the whole book on those topics, and the reader would still want more.
The book's quirky format may annoy some readers. (On the even numbered pages are inspirational quotes from cutters or photos/illustrations; the odd numbered pages contain the text.) But the presentation does make for easy reading. Whether the reader is interested in acquiring performance coaching/positive thinking skills, learning how to cut cattle, or both, Barbara shares enough gems to make this a worthwhile read.

Cool Companies: How the Best Businesses Boost Profits and Productivity by Cutting Greenhouse Gas Emissions
Joseph J. Romm Manufacturer: Island Press ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 1559637099 |
Book Description
Despite ongoing negotiations, consensus has not yet been reached on what action will be taken to combat global warming. A number of companies have looked beyond the current stalemate to see the prospect of reducing greenhouse-gas emissions not as a roadblock to growth and innovation but as a unique opportunity to increase profits and productivity. These "cool" companies understand the strategic importance of reducing heat-trapping emissions and have worked to cut their emissions by fifty percent or more. In the process, they have not only reduced their energy bill, but have increased their productivity, sometimes dramatically.
In Cool Companies, energy expert Joseph Romm describes the experiences of these remarkable firms, as he presents more than fifty case studies in which bottom line improvements have been achieved by improving processes, increasing energy efficiency, and adopting new technologies. Romm places efforts to reduce emissions in the context of proven corporate strategies, showing managers how they can build or retrofit their operations with the latest technologies to reduce emissions and achieve quick returns on the investment. Case studies explain:
In profiling successful companies such as DuPont, 3M, Compaq, Xerox, Toyota, Verifone, Perkin-Elmer, and Centerplex, among many others, Cool Companies turns on its head the notion that the effort to combat global warming will come with massive costs to the industrial sector. It is a unique and essential business book for anyone concerned with increasing profits and productivity while reducing greenhouse gas emissions.
Customer Reviews:
simple approach and numerous examples.......2001-07-24
I approached my own boss with these ideas and received a chuckle in response. Its an uphill fight out there, hopefully the more people become informed, the easier it will be. This book is a great one to hand to a nay sayer. (I plan on sending a copy to both my boss and President Bush for Christmas)
Improving your Bottom Line by Reducing Greenhouse Gases.......2000-06-13
Cool Companies offers insights into the detailed processes by which all company sites-from industrial giants like DuPont and 3M all the way down to individual apartment owners-have used greenhouse gas emission reduction to drive many more dollars to their bottom line.
The only question one is left with after Romm so effectively makes his case is why the coal and oil companies are playing Chicken Little and screaming that reducing greenhouse gases will hurt American business. Obviously, the only American businesses they are referring to must be their own. The Wall Street Journal and the American Chamber of Commerce would be well served to get the true picture and start representing the needs and interests of the majority of their customers-whose interests, at this point, are often diametrically opposed to those of the fossil fuel industry.
Run out and buy this book, before your competitors do.......1999-10-16
If you work anywhere in corporate management -- Whether you are the Chief Operating Officer, The Chief Financial Officer, the Plant Manager, or the Environmental Manager, you need to run out and buy this book, and then read it, before your competitors do.
You'll find case study after case study of how the best companies cut carbon. From building design, to the office environment, to industrial processes on the plant floor, this book tells -- often in the words of the managers themselves -- how they did what they did. Not only the technologies they chose, but how they sold other managers, developed creative financing strategies(often getting projects financed off ledger, out of future savings for example), and obtained credit for cutting other emissions.
If you are an environmentalist or a regulator facing the prospect of a climate treaty, the examples Romm outlines show why the arcane debate about the cost of cutting greenhouse gasses is flat out irrelevant. Cool Companies save money by becoming more efficent.
Bottom line? If you read only one book on cutting greenhouse gasses -- make it this one.

Advanced Metalcutting Calculators in U.S. & Metric Units: Milling, Turning, Boring, Drilling, and Machining Time
Edmund Isakov Manufacturer: Industrial Press ProductGroup: Book Binding: CD-ROM Similar Items: ASIN: 0831132116 |
Product Description
Advanced Metalcutting Calculators contains four calculators, each for major metalcutting operations: Milling, Turning, Boring, Drilling, and one calculator for exact machining time when facing, cutting off, and deep grooving. All calculators are developed in Microsoft Excel, and execute all parameters in both U.S. and Metric units of measure. These calculators provide more accurate computations than any other calculators on the market. They are unique in computing cutting forces, torque values, and required machining power. Additionally, feed and radial cutting forces are calculated by the Turning and Boring Calculator (covered by U.S. Patent No. 6,836,697). Any metalworking professional is sure to find these calculators handy, especially for maximizing productivity of cutting by selecting such parameters at which nominal power of the machine tools can be effectively utilized.
Distinctive Features
- All calculators computer RPM versus selected cutting speed, cutting time, and metal removal rate.
- All calculators compute cutting parameters in customary U.S. and metric units of measurements
Milling Calculator provides advanced computations of
- Cutting force versus tensile strength of work material and area of the chip.
- Torque at spindle versus cutting force and the cutter diameter.
- Area of the chip versus feed per tooth and the depth of cut.
- Adjustments to feed rate depending on the lead angle of the cutter and width of cut.
- Required machining power versus cutting force and cutting speed, or versus torque at spindle and cutters rpm.
Turning Calculator provides advanced computations of
- Cutting force components.
- Torque at spindle versus tangential force and the workpiece diameter.
- Required machining power versus tangential force and cutting speed, or versus torque at spindle and the workpiece rpm when indexable insert of the cutting tool is sharp.
- Required machining power at the moment when insert must be indexed or changed.
Boring Calculator, in addition to the same four feature above, provides advanced computations of
- Deflection versus resultant cutting force, unsupported length of the bar, moment of inertia of the bar cross-sectional area, and the modulus of elasticity of the bar material.
- Modulus of elasticity of the bar material used versus the code assigned to steels, tungsten heavy alloys, and cemented carbides (these materials are used to fabricate boring bars).
Drilling Calculator provides advanced computations of
- Tangential force versus drill diameter, feed rate, power constant of the work material, and the drill wear factor.
- Thrust (axial force) versus tangential force and the coefficient of porportionality.
- Torque at the drill versus tangential force and the drill diameter.
- Required machining power versus tangential force and the cutting speed, or versus torque at the drill and the spindle rpm (for sharp indexable inserts and at the moment when the inserts must be indexed or changed).
- Penetration rate versus feed rate and rpm.
Machining Time Calculator (facing, cutoff, and grooving) provides advanced computations of
- Radius of the workpiece (in inches) when spindle of the machine tool runs at its maximum rpm.
- Machining time when facing or cutting off to the center of the workpiece, min.
- Machining time when deep grooving, facing, or cutting off to a shoulder of the workpiece, min.
