As electrical energy can create mechanical vibrations (perceived as sound by the human ear), so in turn can mechanical vibrations create electrical energy, such as the previously mentioned ball lightning. It could be theorized, therefore, that with the Earth being a source for mechanical vibration, or sound, and the vibrations being of a usable amplitude and frequency, then the Earth's vibrations could be a source of energy that we could tap into. Moreover, if we were to discover that a structure with a certain shape, such as a pyramid, was able to effectively act as a resonator for the vibrations coming from within the Earth, then we would have a reliable and inexpensive source of energy.

A pessimist says the glass is half empty, an optimist says the glass is half full, and an engineer says the glass is too big.

Ask Gandhi, and eye for an eye makes us both blind.....ask an engineer, and the numbers don't lie - the first to strike wins.

A societal revolution is politically organic in nature. It can't be engineered. It has to be evolved.

As we look around the world, especially in Egypt, Lebanon, Turkey, the west coast of Italy, Peru, and Bolivia, there are stone structures and the remains of others which don't easily fit into the standard picture of history. The pyramids of Giza in Egypt, Puma Punku in Bolivia, and the great megalithic wall of Sachsayhuaman in Peru are but three examples of astonishingly well-made stone works which modern engineers, stone masons, and other experts puzzle over. Conventional academics in general date these structures well within the standard timeline of so-called civilization. The generally prescribed creation date of the three pyramids of Giza is about 2500 BC, Puma Punku is alleged to have been constructed around 600 AD, and Sachsayhuaman approximately 1200 to 1400 AD. However, what intrigues engineers, architects, stone masons, and other professionals is the extreme precision of the work, often in very hard stone, which many archaeologists insist was usually achieved using bronze and or copper chisels, wooden measuring devices, and stone hammers.

Character is like 'Structural Integrity' in the field of engineering. A construction is believed to have structural integrity when it can withstand 'impact' from anywhere and anything, functioning adequately for its desired purposes and service life, until a physical collapse proves otherwise. 'Integrity' springs from the original Latin root 'integrum', which means "Intact". A man has INTEGRITY when he remains INTACT, despite the IMPACT of forces that seek to sidetrack him. He will never confuse "what is" with "what ought to be", EVEN WHEN "what is" will work in his favour. A man who will choose, not what the world forces his hands to choose, but what aligns with his destiny and will propel him to become what he is meant to become. Such men are few, such men should be me and you.

Conjugation of the irregular verb “to design”: I create, You interfere, He gets in the way. We cooperate, You obstruct, They conspire.

Current theories regarding the function and construction of the pyramid fall short. A credible theory would have to explain the following conditions found inside the Great Pyramid: -The selection of granite as the building material for the King's Chamber. It is evident that in choosing granite, the builders took upon themselves an extremely difficult task. -The presence of four superfluous chambers above the King's Chamber. -The characteristics of the giant granite monoliths that were used to separate these so-called "construction chambers." -The presence of exuviae, or the cast-off shells of insects, that coated the chamber above the King's Chamber, turning those who entered black. -The violent disturbance in the King's Chamber that expanded its walls and cracked the beams in its ceiling but left the rest of the Great Pyramid seemingly undisturbed. -The fact that the guardians were able to detect the disturbance inside the King's Chamber, when there was little or no exterior evidence of it. -The reason the guardians thought it necessary to smear the cracks in the ceiling of the King's Chamber with cement. -The fact that two shafts connect the King's Chamber to the outside. -The design logic for these two shafts—their function, dimensions, features, and so forth.

Bad design with good materials may give you the designed fatigue life, but a good design with bad materials will never give you the designed fatigue life.

Each type of knowledge has value; however, from an engineering point of view, practical knowledge seems to be more valuable than theoretical knowledge.

Birds fly more efficiently than aeroplanes. Nature is the superior engineer.

Designing Structures is an art and this needs to be transparent, as designs come and go but creativity stays there

Engineering is the art and science of nuts and bolts.

Engineering is defining and following datasheets.If it doesn't work then use common sense.

Engineering is not only study of 45 subjects but it is moral studies of intellectual life.

Engineering is maths & management

Engineering-driven companies falsely assume that because they build it, the industry will magically become aware and be willing to buy it.

Engineers are all too often unsung heroes; if we are ever, in truth, to travel between stars, it will be thanks to their aspirations and imagination... for they are the bridge builders.

E per tutto il giorno mi riempivano la testa di stronzate che volevano farmi tenere a mente, come ad esempio le equazioni per calcolare la distanza fra il posto dove ci trovavamo e quelle in cui volevano farci andare loro, e naturalmente quelle per tornare indietro; cazzate come le coordinate coassiali, il calcolo dei coseni, la trigonometria sferoide, l'algebra di Boolean, gli antilogaritmi, l'analisi di Fourier, quadrati e matrici. Mi dissero che io avrei dovuto fare da riserva al computer di riserva.

Evolution optimizes strongly for energy efficiency because of limited food supply, not for ease of construction or understanding by human engineers.

Expertise in a subfield was the key to a successful career as an engineer, and expertise was becoming a necessity for the mathematicians and computers as well.

Failure analysis is as easy as Monday-morning quarterbacking' design is more akin to coaching. However, the design engineer must do better than any coach, for he is expected to win every game he plays. That is a tough assignment when one mistake can often mean a loss. And when defeat occurs, all one can hope is to analyze the game films and learn from the mistakes so that they are less likely to be repeated the next time out.

For Commander Ripley Jones, it was becoming more and more troublesome. It had been said that nothing is infallible, Antares apparently being the proof. After hastily recalling all crew and leaving Spacedock 7 thirty hours ago, there had been nothing but problems. Breakdowns in the sensors and telemetry, system failures of a wide variety and finally – the Last Straw: a coupling seal in the stardrive engine failed. Fortunately the cut-out worked, or the whole of engineering would’ve disappeared in a flaming ball of anti-matter. Five crewmen were seriously injured as it was. Commander Smith, the Chief Entech, had the offending unit stripped down and under repair. They were currently on conversion drive - which could only propel them at sub-light speeds – and Ripley was currently in an elevator with a very pissed Captain Falconer.

Here is the product of an ancient civilization empowered with the knowledge that as long as the moon continued to orbit the Earth, the special relationship that existed between the two assured the Egyptians of vast amounts of energy. The source of the energy is the Earth itself, in the form of seismic energy. The ancient Egyptians saw tremendous value in this form of energy and expended a considerable amount of effort to tap into it. The benefits they received may have been twofold: energy to fuel their civilization, and the ability to stabilize the Earth's crust by drawing off seismic energy over a period of time rather than allowing it to build up to destructive levels.

How in the fucking hell did you do that?" Calyph shrugged. "I'm an Engineer," he said simply, as if it would explain everything.

If automating everything makes people lazier and lazier, and laziness leads to stupidity, which it does for most people, judging by the current content circulating the social networks everywhere, except North Korea, where they don’t have any internet to speak of - at some point the Japanese robots, for which a market niche is currently being developed, with no concerns on how they should be designed to act in society or outside it - will have no choice, but to take everything over, to preserve us from ourselves…

If you're going to go out, go out in a blaze of glory.

If I were king, I would redress an abuse which cuts back, as it were, one half of human kind. I would have women participate in all human rights, especially those of the mind.

I have seen ideas that work on paper not work in the field. But I have never seen an idea that does not work on paper work in the field.

In 1983 Donald Rahn of Rahn Granite Surface Plate Co. told me that diamond drills, rotating at nine hundred revolutions per minute, penetrate granite at the rate of one inch in five minutes. In 1996, Eric Leither of Tru-Stone Corp. told me that these parameters have not changed since then. The feedrate of modern drills, therefore, calculates to be .0002 inch per revolution, indicating that the ancient Egyptians drilled into granite with a feedrate that was five hundred times greater or deeper per revolution of the drill than modern drills! The other characteristics of the artifacts also pose a problem for modern drills. Somehow the Egyptians made a tapered hole with a spiral groove that was cut deeper through the harder constituent of the granite. If conventional machining methods cannot answer just one of these questions, how do we answer all three?

In accordance with the prevailing conceptions in the U.S., there is no infringement on democracy if a few corporations control the information system: in fact, that is the essence of democracy. In the Annals of the American Academy of Political and Social Science, the leading figure of the public relations industry, Edward Bernays, explains that “the very essence of the democratic process” is “the freedom to persuade and suggest,” what he calls “the engineering of consent.” “A leader,” he continues, “frequently cannot wait for the people to arrive at even general understanding … Democratic leaders must play their part in … engineering … consent to socially constructive goals and values,” applying “scientific principles and tried practices to the task of getting people to support ideas and programs”; and although it remains unsaid, it is evident enough that those who control resources will be in a position to judge what is “socially constructive,” to engineer consent through the media, and to implement policy through the mechanisms of the state. If the freedom to persuade happens to be concentrated in a few hands, we must recognize that such is the nature of a free society.

Indeed, "brute force" solutions are often characteristic of advanced cultures, not primitive ones. The Romans and their predecessors spent a long time figuring out how to build arches... and virtually all our buildings today use post-and-lintel construction, precisely what the arch was devised to replace. We have better materials and more money, and given that, arches are usually not worth the extra complexity.

It did occur to him that perhaps he’d gone to the wrong Academy – the guys in the Space Fleet always had more interesting stories to tell at the spaceport bars. You know, tales about the dude who got vaporized in a plasma accident in the engineering section, or the fella who got turned into a blob of weird space jelly by some alien virus – or the time someone flew a starship into an astor-field at warp four by mistake (they were still trying to find the black box on that one). The Imperial Space Fleet’s recruiting office sure didn’t go around advertising ‘Join up, see the universe, meet interesting aliens and die screaming’, but it was known there were risks involved. It was part of the job after all, and yet somehow, they still got recruits signing up in droves. Yes, indeedy – the stories were far more interesting than his – took a load of ore to Gorda, took a load of mining equipment back to Tordrazil. Took a load of Florpavian Flame-birds to a zoo on Deanna, took a load of machinery to Salus. Picked up and dropped off a few passengers on the way. Still, Florpavian Flame-birds were a risky cargo… and damned tricky to transport – which is probably the only reason he’d had any entertainment at all on the last trip.

I didn't have a drill, so I had to make my own. First I heated a long nail in the fire, then drove it through a half a maize cob, creating a handle. I placed the nail back on the coals until it became red hot, then used it to bore holes into both sets of plastic blades.

if we were to build a Great Pyramid today, we would need a lot of patience. In preparation for his book "5/5/2000 Ice: The Ultimate Disaster", Richard Noone asked Merle Booker, technical director of the Indiana Limestone Institute of America, to prepare a time study of what it would take to quarry, fabricate, and ship enough limestone to duplicate the Great Pyramid. Using the most modern quarrying equipment available for cutting, lifting, and transporting the stone, Booker estimated that the present-day Indiana limestone industry would need to triple its output, and it would take the entire industry, which as I have said includes thirty-three quarries, twenty-seven years to fill the order for 131,467,940 cubic feet of stone. These estimates were based on the assumption that production would proceed without problems. Then we would be faced with the task of putting the limestone blocks in place. The level of accuracy in the base of the Great Pyramid is astounding, and is not demanded, or even expected, by building codes today. Civil engineer Roland Dove, of Roland P. Dove & Associates, explained that .02 inch per foot variance was acceptable in modern building foundations. When I informed him of the minute variation in the foundation of the Great Pyramid, he expressed disbelief and agreed with me that in this particular phase of construction, the builders of the pyramid exhibited a state of the art that would be considered advanced by modern standards.

I have been branded with folly and madness for attempting what the world calls impossibilities, and even from the great engineer, the late James Watt, who said ... that I deserved hanging for bringing into use the high-pressure engine. This has so far been my reward from the public; but should this be all, I shall be satisfied by the great secret pleasure and laudable pride that I feel in my own breast from having been the instrument of bringing forward new principles and new arrangements of boundless value to my country, and however much I may be straitened in pecuniary circumstances, the great honour of being a useful subject can never be taken from me, which far exceeds riches.

I have learned over the years that many formally educated corrosion professionals are either engineers or chemists by training. While those two groups represent the largest two categories of backgrounds in the oilfield corrosion control industry, they are in the minority.

I looked more closely at what I considered to be the most significant information regarding the Great Pyramid, which was the accuracy with which it was built. It soon became obvious to me that the researchers on both sides of the issue were sympathetic to the craftspeople involved in building the pyramids. But the researchers were not craftspeople themselves, and they did not have the perspective gained through years of experience working with their hands and with machinery. Having that experience myself, I have some very strong opinions regarding the level of manufacturing expertise practiced by the ancient Egyptians. They were not primitive by any means, and their craftsmanship and precision would be an extreme challenge to duplicate today.

In engineering colleges, they have seating plans...And Students have cheating plans.

In literature, too, we admire prose in which a small and astutely arranged set of words has been constructed to carry a large consignment of ideas. 'We all have strength enough to bear the misfortunes of others,' writes La Rochefoucauld in an aphorism which transports us with an energy and exactitude comparable to that of Maillard bridge. The Swiss engineer reduces the number of supports just as the French writer compacts into a single line what lesser minds might have taken pages to express. We delight in complexity to which genius has lent an appearance of simplicity. (p 207)

In modern society, it is not enough to be an engineer, a doctor, a chemist, a biologist, or a physicist, you must be all of them to understand why human health is failing on such a massive scale.

In order to draw mechanical vibrations and relieve the stresses that build up within the Earth, we would need an object that would respond sympathetically with the Earth's fundamental frequency. This object would need to be designed in such a way that its own resonant frequency was the same as, or a harmonic of, the Earth's. In this manner, energy transfer from the source would be at maximum load. In harmony with the Earth's vibrations, this object would have the potential to become a coupled oscillator. (A coupled oscillator is an object that is in harmonic resonance with another, usually larger, vibrating object. When set into motion, the coupled oscillator will draw energy from the source and vibrate in sympathy as long as the source continues to vibrate.) Because the Earth constantly generates a broad spectrum of vibration, we could utilize vibration as a source of energy if we developed suitable technology. Naturally, any device that attracted greater amounts of this energy than is normally being radiated from the Earth would greatly improve the efficiency of the equipment. Because energy will inherently follow the path of least resistance, it follows that any device offering less resistance to this energy than the surrounding medium through which it passes would have a greater amount of energy channeled through it. Keeping all of this in mind and knowing that the Great Pyramid is a mathematical integer of the Earth, it may not be so outlandish to propose that the pyramid is capable of vibrating at a harmonic frequency of the Earth's fundamental frequency.

In the one hundred thirty years since Petrie published his seminal studies of the pyramids and temples of Egypt, the hand tools and building and sculpting tools used by men and women have improved exponentially in capability and efficiency and hard drives are better known as integral devices in a computer. Yet we are taught that during the three thousand years that the ancient Egyptians flourished on this planet, the tools used by men and women did not change. How could this be? The finely crafted and precise boxes inside the pyramids at Giza were supposedly created in the fourth dinasty, 2500 BCE, or forty-five hundred years ago. The finely crafted and precise boxes inside the rock tunnels of the Serapeum were supposedly created in the eighteenth dynasty, 1550-1200 BCE, or thirty-five hundred years ago. We are asked to believe that in a one-thousand-year span, the ancient Egyptians did not make any significant improvement in their tools and methods for cutting hard igneous rock. We, however, have examined the results of their labor, and it is clear that the Egyptians were not stupid people. In fact, they were geniuses in their accomplishments, yet we are to accept that while they tapped into the awesome power of the human spirit and creativity, they did not ask, over the course of a full millennium, how they could do their job better--how they could demand less pain and strain from their workforce, how they could do more with less effort, how they could reduce injuries and provide workers with more time off. If there is any mystery to ancient Egypt, it is why a paradigm that was established one hundred thirty years ago still holds force among many Egyptologists and archaeologists.

It is contrary to the usual practice of professional men to give their opinions upon each other's work unless regularly called upon in the way of their profession.

It now remains for those who are absolutely convinced that the ancient Egyptians constructed the pyramids using primitive techniques to build a pyramid themselves, using those same techniques that they propose the Egyptians used. As part of such an attempt, it would help if they cut out just one seventy-ton block of granite from the Aswan quarry, which is located five hundred miles away, using their hardened copper chisels or dolerite balls and then transported the block to the Giza Plateau with their barges, ropes, and manpower. If the proponents of traditional theories of constructing the pyramids are able to accomplish this feat, then we should give serious consideration to their proposals about pyramid construction.

Math is my Passion. Engineering is my Profession.

Mister Geoffrey, my experiment shows that the dynamo and the bulb are both working properly," I said. "So why won't the radio play?" "I don't know," he said. "Try connecting them here." He was pointing toward a socket on the radio labeled "AC," and when I shoved the wires inside, the radio came to life. We shouted with excitement. As I pedaled the bicycle, I could hear the great Billy Kaunda playing his happy music on Radio Two, and that made Geoffrey start to dance. "Keep pedaling," he said. "That's it, just keep pedaling." "Hey, I want to dance, too." "You'll have to wait your turn." Without realizing it, I'd just discovered the difference between alternating and direct current. Of course, I wouldn't know what this meant until much later. After a few minutes of pedaling this upside-down bike by hand, my arm grew tired and the radio slowly died. So I began thinking, "What can do the pedaling for us so Geoffrey and I can dance?

Nothing is easier than yesterday's solutions.

I was hoping to be able to get into the Queen's Chamber while I was in Egypt in 1986 to get a sample of the salt for analysis. I had speculated that the salt on the walls of the chamber was an unwanted, though significant, residual substance caused by a chemical reaction where hot hydrogen reacted with the limestone. Unfortunately, I was unable to get into the chamber because a French team was already inside the Horizontal Passage, boring holes into what they hoped were additional chambers. (It was discovered, after I left Egypt, that the spaces contained only sand.) As it turned out, my research would have been redundant. Noone reported in his book that another individual had already had the same idea and done the work. In 1978, Dr. Patrick Flanagan asked the Arizona Bureau of Geology and Mineral Technology to analyze a sample of this salt. They found it to be a mixture of calcium carbonate (limestone), sodium chloride (halite or salt), and calcium sulfate (gypsum, also known as plaster of paris). These are precisely the minerals that would be produced by the reaction of hot, hydrogen-bearing gas with the limestone walls and ceiling of the Queen's Chamber. [...] The interior chambers of the Great Pyramid have the appearance of being subjected to extreme temperatures; and [...] the broken corner on the granite box shows signs of being melted, rather than simply being chipped away.

On a world built to ordered specification, there was no logical reason for such a mountain to exist. Yet every world should have at least one unclimbable mountain.
