The word engineer comes from the Greek terms enkolos and kosmos, meaning “work of art” and “work of science.” Engineers apply science and math to understand and predict the behavior of fluids and gases, and to make use of tools and equipment that helps them function in machines.
During the Renaissance, Italy became known as the Italy of reptiles, from the belief that poisonous water from the nearby volcano of Venetica would cure disease and save lives. Engineers came to study the venoms and devised ways to use metals to poison water. Devices were created to remove poison through the expenditure of water, and aelected doctor to discover a means to insulate houses from water.
During this period, a British engineer named Richard Trevithick was appointed to find a way to obtain amounts of pure water without using fire, thereby saving people and animals from fire. Trevithick discovered that by withdrawing a single penny from a bury in the ground, he could obtain 1,000 gallons of water. It is on this water that he had built a device that could extract pure water from evaporation. Also, notable inventions that came from this brilliant engineering concept is spray foam systems.
The Trevithick Water distillation device was crude but successful. He diluted a gallon of water by half a liter and then added it to an eight ounce serving of milk. By next morning, the milk was near paste. The proof that raw water could be transformed into commercially available drinking water was untested. While the principle was not invented, the water was successfully stored and used for centuries.
The next great water story we hear about is from Mohammed bin Tathaggar A league of merchants came to the capital of the kingdom of Harunbad and announced their arrival. They were seeking a distribution network. Harunbad was divided into 30 townships and each township had 100 families. Each group pitched tents by the side of the main highway, shaded by desert sand dunes. The workers spread out over the area but didn’t seem to mind the heat. They offered their services to Hasiba, the ruler. He ignored them and instead focused on his most important problem, the conversion of women to Islam. Once again, he had a trump card to play. A special breed of dog was imported and people soon came to call it ‘ magician’s dog ‘ for it was said that it could hypnotize even the most seasoned traveler.
It was at this time, that irrigation was invented. The dog was soon used in the agriculture and shepherding trade. The shepherds would use the dog to herd their flocks of sheep. Farmers would stack the sheaves of garlic and put them on the dog, who would then walk around in a circle and herd the sheep. The larger the stack of garlic the more food the dog would fetch.
Why does the story of the dog have more verses than all the other Bible stories? The answer is simple. People have loved dogs from a very long time. Elijah, the prophet who lived 2000 years ago, is credited with having written more than 250 poems about dogs. Some have even called him the poet of dogs.
Dogs are mentioned in the Old Testament not as a pet but as a symbol of salvation. In that book it is written: “Behold, a dog came to him, and he ordered him to set it up in a pile beside him. And he said to John, ” Here am I indeed, the God’s messenger. Send to him whatever you may, that he may be helped.” (John 1: 11)
Cats were known as pets in all the world. Romans called the cat goddess Bastet. Egyptian cats were called kittens. puppies from Egypt are called emeralds. From the poem ‘Old Cats’ by Percy Bridgman; ‘all the cats gathered round about the place where the moon met the sun,’ we learn that cats were valued for their mystical powers. ‘The gods,’ said the cats, ‘were very angry one day when kittens came from the land of kittens and settled here under the feet of gods.’ ( Percy Bridgman, ‘ Cats’, book 27, verse 28)
fleas on dogs are mentioned several times in the Bible. They are especially significant when God orders the animals to separate for forty days and nights before he will ‘mmediately’ take them off to be slaughtered. (I Kings 3:26) ‘Moreover the LORD spoke to Moses, saying, “I will be as though I were but now a cat from among you, and I will walk alongside you; I will be a firefly among you, and I will relief you from affliction. I will be a furry toy for your children. I will be a thing that will be pulled and carried, a thing that will be caught and carried.’ (rought to you for catching mice).
In the bible we even have a mention of ‘clean beasts’.
