What we have been taught is that the ancient Egyptians were in posession of only simple hand tools, and that the only metals available to the Egyptians of the fourth dynasty, when the Giza Pyramids were built, were copper, gold, and silver. What is inferred, therefore, is that absent the tools made from these materials, the simple abrasive experiments actually demonstrate the stone-working methods of ancient Egypt. We are told that the ancient Egyptians had not yet developed the knowledge to extract the raw materials necessary to produce iron and steel. It has been suggested that they may have used meteoric iron, because they found it lying on the ground, but they did not mine the ore and smelt it in a foundry. Support for this view is the lack of evidence that they used tools made of any material other than copper, stone, and wood. Yet absence of evidence is not evidence of absence. Although sophisticated tools made of iron or steel may not yet have been discovered in the archaeological record, what has been found is not adequate enough to explain how the artifacts were created.

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.

The knowledge needed to evaluate certain of these ancient artifacts was not available until very recently. Even today there may be numerous articles that we will not understand until we further develop our own technology. We cannot fathom technology that is unknown to us, and we seldom consider things that seem impossible to us. Petrie, though knowledgeable in engineering and surveying, could not be expected to know anything about ultrasonic machining; hence his amazement at the machining abilities of the ancient Egyptians. Even if he had been aware of this technology, the intellectual climate of his time may have precluded his considering the possibility that these methods were known to the ancient Egyptians. Quite simply, the greatest barrier to our understanding may not necessarily be knowledge. It may be attitude.

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

Stephenson had large wrought-iron boiler plates available and he also had the courage of his calculations... The idea found its best-known expression in the Menai railway bridge opened in 1850. Stephenson's beams, which weighed 1,500 tons each, were built beside the Straits and were floated into position between the towers on rafts across a swirling tide. They were raised rather over a hundred feet up the towers by successive lifts with primitive hydraulic jacks. All this was not done without both apprehension and adventure; they were giants on the earth in those days.

We tend to hear much more about the splendors returned than the ships that brought them or the shipwrights. It has always been that way. Even those history books enamored of the voyages of Christopher Columbus do not tell much about the builders of the Nina the Pinta and the Santa Maria or about the principle of the caravel. These spacecraft their designers builders navigators and controllers are examples of what science and engineering set free for well-defined peaceful purposes can accomplish. Those scientists and engineers should be role models for an America seeking excellence and international competitiveness. They should be on our stamps.

I need to discuss science vs. engineering. Put glibly: In science if you know what you are doing you should not be doing it. In engineering if you do not know what you are doing you should not be doing it.

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.

America is inching towards the metric system

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 went to school at night in L.A. to brush up on my engineering while I applied to the astronaut program. I really did not know if I would get in. It was the year after the Challenger accident in 1987.

During the nineteenth century, the rapid emergence and proliferation of new manufacturing methods and building technologies led to the establishment of polytechnic schools that concentrated on the practicalities of engineering and construction rather than the niceties of stylistic correctness or adherence to established precedent.

I don't know why I always liked aerospace engineering. I was in the 10th grade when I figured that's what I wanted to do.

I'm an engineer. I studied physics and engineering. In fact, in 1978 I started working as an aerospace engineer with General Dynamics. I used to test cruise missiles, space systems, I worked on the first generation of cruise missile.

No matter what engineering field you're in, you learn the same basic science and mathematics. And then maybe you learn a little bit about how to apply it.

Software is a great combination between artistry and engineering.

The process of shaping opinion, attitudes, and perceptions was termed the 'engineering of consent' by one of the founders of the modern public relations industry, Edward Bernays.

Aviation is the branch of engineering that is least forgiving of mistakes.

Asian countries produce eight times as many engineering bachelors as the United States, and the number of U.S. students graduating at the masters and PhD levels in these areas is declining.

Shiv Nadar University was established in 2011, and our first batch graduated in 2015. The first batch mostly had engineering courses and a B.Sc. programme in Mathematics.
