Well, the simple answer is we didn't. The more complicated answer involves, if you want to believe these kinds of things, extraterrestrial technology. It's hard to provide evidence on something your government doesn't, at all costs, regard at true for some strange reason. But evidence for this claim ofnon-human technologies "leaking" into the corporate sector can be found and many places if you know where to look. For example, one company which receives a great deal of money from both the U.S. military and NASA is the Analex company. And I don't know if they changed this on their site for obvious reasons or not, but much of the company's doings are in "retro-engineering". One must ask themselves, what would a company in the world's technological super power, let along one funded by NASA, ever find themselves with the need to retro-engineer technology, presumably being the foremost in technology?
It wouldn't be worth mentioning if it was a singular case, but...
Sadly, you can find companies like this all over, typically concerning military, aeronautics, or advanced medicine and computing, ect... It's great that the technology is springing up, its sad that few people are bringing the technology's origin to public attention however. Chances are, as with all technology, we just *need* to misuse it for a little while first.
The point of impact or cataclysmic event.
Mayans developed zero as a placeholder around A.D. 350 and used it to denote a placeholder in their elaborate calendar systems. But Mayans never used zero in equations.
The term ground zero describes the point on the Earth's surface closest to a detonation. In the case of an explosion above the ground, ground zero refers to the point on the ground directly below the detonation. The origins of the term ground zero began with the Manhattan Project and the bombing of Japan.

Henri Becquerel discovered in 1896 the natural radioactivity.
zero point energy generators exist in the modern world only in theory. Any you find that have been made are scams. Scientifically, the zero point energy generator is an ideal that cannot yet be reached.
Yes! Absolute zero has minimal kinetic energy.
The kinetic energy of the car becomes zero when the car halts. If it halts on top of a hill, the energy changes to potential energy.
Zero point energy, or the energy of the vaccum, remains speculative. No one is currently using it for anything, and no one knows how to access it, if such a thing indeed will ever be possible.
The nature of dark energy is currently not fully understood. It might be related to zero-point energy... but if it is, the question arises why the density of dark is about 120 orders of magnitude less than the theories of zero-point energy predict. Predicting that the observable Universe has exactly one atom would be more accurate than that.
There are no references online to this exact expression, but perhaps it refers to Zero Point Energy which is the energy still present even when matter has been cooled to absolute zero. This energy is locked up within the atom in the form of particle spin and electron orbit momentum as well as more exotic quantum effects. There is speculation that zero point energy and a corresponding zero point field is part of the most fundamental properties of matter and of the universe as a whole.
Absolute zero. On the Kelvin scale of heat measurement, 0K is the point at which no more energy can be removed or −273.15°C / −459.67°F. There is not enough energy there at 0K to transfer any movement from the substance to another substance.
Because absolute zero (or 0k) is the point at which EVERYTHING freezes. More specifically, absolute zero is defined to be the point where there is no energy. You can't have less than no energy.
Space-energy, also known as zero-point energy is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state, which is non-zero.
zero discovered in India in 400 BC in maharashtra
At the low point of a swinging pendulum, the type of energy being demonstrated is maximum kinetic energy. It has zero potential energy at this point of the swing.
