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 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.

Nothing is easier than yesterday's solutions.

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.

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.

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?

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.

One also finds, even to this day, some amazing works such as the aforementioned Sachsayhuaman and the Coricancha in Cusco, where no mortar of any kind was used. It was stone-on-stone, with astonishing accuracy of fit. In the Inca toolkit, as found in the archaeological record, only copper and bronze chisels have been found, along with wooden measuring instruments and stone pounders or hammers. Conventional archaeologists contend that such tools were responsible for the refined workmanship seen in Cusco and other 'Inca' areas. However, the stone used - granite, andesite, and basalt - are harder than the majority of the tools used, and thus could not have been responsible for the work. The same is true of Tiwanaku and the connected site of Puma Punku. Massive megalithic blocks with sculpted surfaces are found at these locations, made of local sandstone, which would be difficult to shape with bronze chisels and stone hammers. However, the real enigmas are the even harder andesite and basalt stones, cut and shaped with such precision that modern engineers, stone masons, and other professionals question how such work could have been achieved without at least 20th century technology.

One of my friends compared me to Bruce Banner, due to my work with radiation and human health. So I looked up Bruce Banner and this is what I found: Banner, a physicist, is sarcastic and seemingly very self-assured when he first appears in Incredible Hulk #1, but is also emotionally withdrawn in most fashions...Banner is considered one of the greatest scientific minds on Earth, possessing "a mind so brilliant it cannot be measured on any known intelligence test." He holds expertise in biology, chemistry, engineering, physiology, and nuclear physics.

Philosophy in its old form could exist only in the absence of engineering, but with engineering in existence and daily more active and far reaching, the old verbalistic philosophy and metaphysics have lost their reason to exist. They were no more able to understand the "production" of the universe and life than they are now able to understand or grapple with "production" as a means to provide a happier existence for humanity. They failed because their venerated method of "speculation" can not produce, and its place must be taken by mathematical thinking. Mathematical reasoning is displacing metaphysical reasoning. Engineering is driving verbalistic philosophy out of existence and humanity gains decidedly thereby. Only a few parasites and "speculators" will mourn the disappearance of their old companion "speculation." The world of producers -the predominating majority of human beings- will welcome a philosophy of ordered thought and production.

Pornography wants to suck you up. Once you got sucked up… you are going to be manipulated by social engineering.

Programmers are isolated. They sit in their cubicle; they don't think about the larger picture. To my mind, a programmer is not an engineer, because an engineer is somebody who starts with a social problem that an organization or a society has and says, "OK, here's this problem that we have- how can we solve it?" The engineer comes up with a clever, cost-effective solution to address that problem, builds it, tests it to make sure it solves the problem. That's engineering.

Scientists and inventors of the USA (especially in the so-called "blue state" that voted overwhelmingly against Trump) have to think long and hard whether they want to continue research that will help their government remain the world's superpower. All the scientists who worked in and for Germany in the 1930s lived to regret that they directly helped a sociopath like Hitler harm millions of people. Let us not repeat the same mistakes over and over again.

Smyth is credited for noting another anomaly in the Queen's Chamber—there were flakes of white mortar exuding from stone joints inside the shaft. Analysis of the mortar found it to be plaster of paris—gypsum (calcium sulfate). Smyth also described this chamber as having a foul odor, which caused early visitors to the chamber to beat a hasty retreat, and it was assumed that tourists were relieving themselves, though the way Smyth described this chamber, few people stayed long enough to do so. However, as I will make clear, this odor may not have been the result of unhygienic conditions but of the chemical process that once occurred in the Queen's Chamber. One of the greatest mysteries of this chamber has been the salt encrustation on the walls. It was up to one-half-inch thick in places, and Petrie took it into account when he made measurements of the chamber. The salt also was found along the Horizontal Passage and in the lower portion of the Grand Gallery. How did salt come to build up on the walls?

Steiger presented another analysis by a professional engineer, who saw the wall carvings at Dendera as an accurate illustration of an electrical device—one which would not be out of place in a modern electrical blueprint file. "In regards to the ancient Egyptian electron tubes, electromagnetic engineer Professor S.R. Harris identified a box-and braided cable in the picture as 'virtually an exact copy of engineering illustration used today for representing a bundle of conducting wires.' The cable runs from the box the full length of the floor and terminates at both the ends and at the bases of two peculiar objects resting on two pillars. Professor Harris is said to have identified these representations as high voltage insulators.

Structure Design must be safe and sound such that the exterior looks will magnetise the cameras from every nook and corner

Subsequent experiments conducted by Tom Danley in the King's Chamber of the Great Pyramid and in Chambers above the King's Chamber suggest that the pyramid was constructed with a sonic purpose. Danley identifies four resident frequencies, or notes, that are enhanced by the structure of the pyramid, and by the materials used in its construction. The notes form an F Sharp chord, which according to ancient Egyptian texts were the harmonic of our planet. Moreover, Danley's tests show that these frequencies are present in the King's Chamber even when no sounds are being produced. They are there in frequencies that range from 16 Hertz down to 1/2 Hertz, well below the range of human hearing. According to Danley, these vibrations are caused by the wind blowing across the ends of the so-called shafts—in the same way as sounds are created when one blows across the top of a bottle.

The backbone of the electrical grid is largely massive numbers of steam driven engines that turn electrical generators.

The brain can be put to better use by reducing anxiety, just as reducing friction between threads can increase the torque transferred to the axial load.

The evidence presented in this book, for the most part, was recorded many years ago by men of integrity who worked in the fields of archaeology and Egyptology. That much of this evidence was misunderstood only reveals the pressing need for an interdisciplinary approach to fields that have until recently been closed to nonacademics and others outside the fold of formal archaeology and Egyptology. Much of our ignorance of ancient cultures can be placed at the feet of closed-minded theorists who ignore evidence that does not fit their theories or fall within the province of their expertise. Sometimes it takes a machinist to recognize machined parts or machines! As a result, much of the evidence that supports a purpose for the Great Pyramid as anything other than a tomb has been ignored, discounted without serious consideration, or simply explained away as purely coincidental. Is it coincidence that the Great Pyramid is so huge and so precise? That the King's Chamber contains so many indications that tremendous forces disturbed it or were created within it at one time? Are the exuviae, the chocolate-colored granite, the resonating chambers with their giant granite monoliths placed above, and the unique properties of the quartz crystal present in vast quantities in the granite complex all coincidental? Can the design and physical tests of the movement of sound inside the Grand Gallery be just a happy accident?

The Fukushima nuclear complex went on to become the worst man-made engineering disaster in all of human history, outside of war.

The granite complex inside the Great Pyramid, therefore, is poised ready to convert vibrations from the Earth into electricity. What is lacking is a sufficient amount of energy to drive the beams and activate the piezoelectric properties within them. The ancients, though, had anticipated the need for more energy than what would be collected only within the King's Chamber. They had determined that they needed to tap into the vibrations of the Earth over a larger area inside the pyramid and deliver that energy to the power center—the King's Chamber —thereby substantially increasing the amplitude of the oscillations of the granite. Modern concert halls are designed and built to interact with the instruments performing within. They are huge musical instruments in themselves. The Great Pyramid can be seen as a huge musical instrument with each element designed to enhance the performance of the other. While modern research into architectural acoustics might focus predominantly upon minimizing the reverberation effects of sound in enclosed spaces, there is reason to believe that the ancient pyramid builders were attempting to achieve the opposite. The Grand Gallery, which is considered to be an architectural masterpiece, is an enclosed space in which resonators were installed in the slots along the ledge that runs the length of the gallery. As the Earth's vibration flowed through the Great Pyramid, the resonators converted the vibrational energy to airborne sound. By design, the angles and surfaces of the Grand Gallery walls and ceiling caused reflection of the sound, and its focus into the King's Chamber. Although the King's Chamber also was responding to the energy flowing through the pyramid, much of the energy would flow past it. The specific design and utility of the Grand Gallery was to transfer the energy flowing through a large area of the pyramid into the resonant King's Chamber. This sound was then focused into the granite resonating cavity at sufficient amplitude to drive the granite ceiling beams to oscillation. These beams, in turn, compelled the beams above them to resonate in harmonic sympathy. Thus, with the input of sound and the maximization of resonance, the entire granite complex, in effect, became a vibrating mass of energy.

Math is my Passion. Engineering is my Profession.

Progress depends on the unreasonable man.

The precision in these artifacts is irrefutable. Even if we ignore the question of how they were produced, we are still faced with the question of why such precision was needed. Revelation of new data invariably raises new questions. In this case it is understandable for skeptics to ask, "Where are the machines?" But machines are tools, and the question should be applied universally and can be asked of anyone who believes other methods may have been used. The truth is that no tools have been found to explain any theory on how the pyramids were built or the granite boxes were cut. More than eighty pyramids have been discovered in Egypt, and the tools that built them have never been found. Even if we accepted the notion that copper tools are capable of producing these incredible artifacts, the few copper implements that have been uncovered do not represent the number of such tools that would have been used if every stonemason who is supposed to have worked on the pyramids at just the Giza site owned one or two. In the Great Pyramid alone there are an estimated 2,300,000 blocks of stone, both limestone and granite, weighing between two-and-one-half tons and seventy tons each. That is a mountain of evidence, and there are no tools surviving to explain even this one pyramid's creation.

The quantity of stone that had to be quarried, hauled, and hoisted into place in the Great Pyramid becomes even more impressive when it is compared with other civil engineering feats, whether real or imagined. It has been stated that it contains more stone than that used in all the churches, cathedrals, and chapels built in England since the time of Christ. Thirty Empire State Buildings could be built with the estimated 2,300,000 stones. A wall three-feet high and one-foot thick could be built across the United States and back using the amount of masonry contained in the Great Pyramid.

The progressive stack is basically a measure of how much you aren’t like, say, James Watt, the developer of the modern steam engine, the key invention of the Industrial Revolution. Watt was white, male, Protestant, straight, rich, mechanically skilled, and a scientific genius, so you’d better not be.

There are hundreds of miracles within a single machine. Americans calmly explain these with mathematical formulas. Our difficulty is to learn, theirs to appreciate. We Latins, even the most intelligent of us, still count on our fingers and toes. But once we do learn, we shall surpass the Americano, because we understand the spiritual significance of a machine. We see the beauty of combining gas, grease and steel into a powerful, exact movement. We appreciate the material destiny of the universe.

There was no room for dust devils in the laws of physics, as least in the rigid form in which they were usually taught. There is a kind of unspoken collusion going on in mainstream science education: you get your competent but bored, insecure and hence stodgy teacher talking to an audience divided between engineering students, who are going to be responsible for making bridges that won’t fall down or airplanes that won’t suddenly plunge vertically into the ground at six hundred miles an hour, and who by definition get sweaty palms and vindictive attitudes when their teacher suddenly veers off track and begins raving about wild and completely nonintuitive phenomena; and physics students, who derive much of their self-esteem from knowing that they are smarter and morally purer than the engineering students, and who by definition don’t want to hear about anything that makes no fucking sense. This collusion results in the professor saying: (something along the lines of) dust is heavier than air, therefore it falls until it hits the ground. That’s all there is to know about dust. The engineers love it because they like their issues dead and crucified like butterflies under glass. The physicists love it because they want to think they understand everything. No one asks difficult questions. And outside the windows, the dust devils continue to gambol across the campus.

There is a frequent tendency in the presentation of mechaincs to use problems mainly as a vehicle to illustrate theory rather than to develop theory for the purpose of solving problems. When the first view is allowed to predominate, problems tend to become overly idealized and unrelated to engineering with the result that the exercise becomes dull, academic, and uninteresting. This approach deprives the students of valuable experience in formulating problems and thus of discovering the need for and meaning of theory. The second view provides by far the stronger motive for learning theory and leads to a better balance between theory and application. The crucial role played by interest and purpose in providing the strongest possible motive for learning cannot be overemphasized." Glenn Kraige, from Merriam & Kraige's Dynamics text, 7th Edition.

There is much which we must leave, whether we like it or not, to the un-"scientific' narrative method of the professional historian.

There were endless stories locked into the silent, cool mass of the Wall, so many memories of stories of so long ago, now only to be imagined. What an incredible feat of human imagination and engineering. A real tribute to visionary and tenacious (if tyrannical) leaders who held a nation together with a common goal, from dynasty to dynasty over the many centuries.

The success of project greatly dependent on periodic visualization of outcome.

Ultrasonic drilling fully explains how the holes and cores found in the Valley Temple at Giza could have been cut, and it is capable of creating all the details that Petrie and I puzzled over. Unfortunately for Petrie, ultrasonic drilling was unknown at the time he made his studies, so it is not surprising that he could not find satisfactory answers to his queries. In my opinion, the application of ultrasonic machining is the only method that completely satisfies logic, from a technical viewpoint, and explains all noted phenomena. [...] The most significant detail of the drilled holes and cores studied by Petrie was that the groove was cut deeper through the quartz than through the feldspar. Quartz crystals are employed in the production of ultrasonic sound and, conversely, are responsive to the influence of vibration in the ultrasonic ranges and can be induced to vibrate at high frequency. When machining granite using ultrasonics, the harder material (quartz) would not necessarily offer more resistance, as it would during conventional machining practices. An ultrasonically vibrating tool bit would find numerous sympathetic partners, while cutting through granite, embedded right in the granite itself. Instead of resisting the cutting action, the quartz would be induced to respond and vibrate in sympathy with the high-frequency waves and amplify the abrasive action as the tool cut through it.

To provide simple scientific solutions to complex design problems is the job of an Engineer

Women, on the other hand, had to wield their intellects like a scythe, hacking away against the stubborn underbrush of low expectations.

Unfortunately, humans have a long history of trying to fix their engineering mistakes with more engineering mistakes!

While infrasonic vibrations at around 6 hertz may influence the brain and produce various effects in humans, it seems that there must be other types of energy, or other frequencies, to explain phenomena that were noted to have occurred at the Great Pyramid more than one hundred years ago. Sir William Siemens, an Anglo-German engineer, metallurgist, and inventor, experienced a strange energy phenomenon at the Great Pyramid when an Arab guide called his attention to the fact that, while standing on the summit of the pyramid with hands outstretched, he could hear a sharp ringing noise. Raising his index finger, Siemens felt a prickling sensation. Later on, while drinking out of a wine bottle he had brought along, he experienced a slight electric shock. Feeling that some further observations were in order, Siemens then wrapped a moistened newspaper around the bottle, converting it into a Leyden jar. After he held it above his head for a while, this improvised Leyden jar became charged with electricity to such an extent that sparks began to fly. Reportedly, Siemens' Arab guides were not too happy with their tourist's experiment and accused him of practicing witchcraft. Peter Tompkins wrote, "One of the guides tried to seize Siemens' companion, but Siemens lowered the bottle towards him and gave the Arab such a jolt that he was knocked senseless to the ground. Recovering, the guide scrambled to his feet and took off down the Pyramid, crying loudly.

Rudolph Gantenbrink's important discovery [of a door with metallic handles found with a robot inside a shaft in the Great Pyramid] has forced many Egyptologists to finally accept that their theories are flawed. This is an interesting development. Academic mores normally dictate that when a theory contains flaws, or unsubstantiated data that supports critical elements on which the theory is built, the entire theory must either be thrown out or revised. Instead of the tomb theory being dismissed, however, Gantenbrink himself was dismissed from the project. He discovered the "door" on March 22, 1993. A week later, he was told to pack up his robot and leave Egypt. Gantenbrink has the technology to go beyond the so-called door but, presumably because of political reasons, has been refused permission to resume his research in Egypt. Gantenbrink, with an engineer's typical pragmatism, stated, 'I take an absolute neutral position. It is a scientific process, and there is no need whatsoever to answer questions with speculation when these questions could be answered much more easily by continuing the research. Yet because of a stupid feud between what I call believers and non-believers, I am condemned as someone who is speculating. But I am not. I am just stating the facts. We have a device [ultrasonic] that would discover if there is a cavity behind the slab. It is nonsensical to make theories when we have the tools to discover the facts.

When we study the past seeking evidence of a highly advanced culture, we should not expect to find objects that we associate with our own culture. Different cultures develop along different paths. This process occurs even over relatively short periods of time, especially when one society is isolated from others. For example, when the Allies went into Germany after Hitler's defeat, they found that after only twelve years of isolation German technology was being developed along lines vastly different from our own. Pauwels and Bergier wrote: 'When the War in Europe ended on May 8th, 1945, missions of investigation were immediately sent out to visit Germany after her defeat. Their reports have been published; the catalogue alone has 300 pages. Germany had only been separated from the world since 1933. In twelve years the technical evolution of the Reich developed along strangely divergent lines. Although the Germans were behindhand as regards the atomic bomb, they had perfected giant rockets unmatched by any in America or Russia. They may not have had radar, but they had perfected a system of infra-red ray detectors which were quite as effective. Though they did not invent silicones, they had developed an entirely new organic chemistry, based on the eight-ring carbon chain. [...] They had rejected the theory of relativity and tended to neglect the quantum theory. [...] They believed in the existence of eternal ice and that the planets and the stars were blocks of ice floating in space. If it has been possible for such wide divergencies to develop in the space of twelve years in our modern world, in spite of the exchange of ideas and mass communications, what view must one take of the civilizations of the past? To what extent are our archaeologists qualified to judge the state of the sciences, techniques, philosophy and knowledge that distinguished, say, the Maya or Khmer civilizations?

With such a convincing collection of artifacts that prove the existence of precision machinery in ancient Egypt, the idea that the Great Pyramid was built by an advanced civilization that inhabited the Earth thousands of years ago becomes more admissible. I am not proposing that this civilization was more advanced technologically than ours on all levels, but it does appear that as far as masonry work and construction are concerned they were exceeding current capabilities and specifications.

A beaver does not, as legend would have it, know which direction the tree will fall when he cuts it, but counts on alacrity to make up for lack of engineering expertise.

A company that cannot successfully implement the 5S's cannot expect to effectively integrate JIT, re-engineering, or any other large-scale change. Good workplaces develop beginning with the 5S's. Bad workplaces fall apart beginning with the 5S's.

A failed structure provides a counterexample to a hypothesis and shows us incontrovertibly what cannot be done, while a structure that stands without incident often conceals whatever lessons or caveats it might hold for the next generation of engineers.

Advanced engineering always, like advanced everything else, brings down upon it the discredit of ridicule of minds who cannot see so far.

After graduating in engineering I went to the University of Kansas to get an MA in economics as a vehicle for allowing me to decide if I wanted to continue in economics.

Yet through their endeavor, men would glimpse the unimaginable artistry of Yahweh's work, in seeing how ingeniously the world had been constructed. By this construction, Yahweh's work was indicated, and Yahweh's work was concealed.

Ah, bien je prétends que les courbes des quatre areêtes du monument, telles que le calcul les a fournies, donneront une grand impression de force et de beauté. Well, I think the curves of the four pillars of the monument, as the calculations have provided them, give it a great sense of force and beauty.
