The Three Laws of Robots

First law

Robot may not harm on humans,

additionally,they may not danger to human,or be the cause to harm the humans.

(do not inflict harm on human)

Second law

Robot cannot disobey commands from humans.

however,if the commands contravene the first law,this limit does not apply.

(obey humans commands)

Third law

Robot must protect its own existence,

as long as doesn't conflict with first law and second law.

(self-preservation)

Conclusion,
 remember the basic of the life

VIMANAS, ancient flying technology

"Vimanas" which are the flying machines described in the ancient Indian Sanskrit epics which are a series of ancient historical writings much larger then Bible that make the construct of Hinduism. It occurs in the Sanskrit epics Yajurveda, the Ramayana, the Mahabharata, the Bhagavata Purana, as well as in classical Indian literature. These texts describe the size and the mechanical workings of the various flying machines.

They explain how they where controlled, special precautions that had to be taken on long flights, how the machines could be protected against violent storms and lightning, how to make a forced landing and even how to switch to solar energy while in flight.

Yea, and were talking thousands of years ago. Something that's very interesting is the fact that the only translations that could not be translated were the descriptions of the various metals and alloys that were used. There's lots of technical detail about the different metals, heat-absorbing metals, their melting point and the type of propulsion units that were used. There are 16 kinds of heat-absorbing metals with names like ushnambhara, ushnapaa and raajaamlatrit non of which can be translated into English.

A book written by David W .Davenport, an Englishman born in India claimed to have proof that Mohenjo Daro, which is more than 5000 years old, was destroyed by an atomic bomb of some sorts. In his book "Atomic Destruction 2000. BC" Davenport demonstrates that there were three different degrees of devastation which spread from the center outwards. Some type of enormous heat was unleashed at the center which created total destruction. Thousands of christened black stones found by archaeologists, turned out to be fragments of clay vessels which had melted into each other due to extreme heat.

The possibility of volcanic eruption is not possible because there is no evidence of hardened lava or volcanic ash. Davenport assumed that the brief intensive heat reached approximately 3632 degrees F (2000 C). He also states that there were numerous skeletons of people lying flat on the ground, often found hand in hand as if they had suddenly been overcome by an unexpected catastrophe.

Parallel Port (RS 232)

Parport is a driver for the traditional PC parallel port. The port has 17 physical pins and 8 ground pins that make a total of 25 pin. The original parallel port divided those pins into three groups: data, control, and status. The data group consists of 8 output pins, the control group consists of 4 pins, and the status group consists of 5 input pins.
In the early 1990’s, the bidirectional parallel port was introduced, which allows the data group to be used for output or input. The HAL driver supports the bidirectional port, and allows the user to set the data group as either input or output. If configured as output, a port provides a total of 12 outputs and 5 inputs. If configured as input, it provides 4 outputs and 13 inputs.
