    MEKELE, Ethiopia (Reuters) - The 54-year-old inventor and repairman supplies Mekele, and indeed the whole of the hilly Tigray region, with coffee machines. But it is his choice of materials that makes Azemeraw's trade truly unique. "The farmers bring me mortar shells from the old battlefield," he says, gesturing north where Ethiopia borders Eritrea and the two nations fought a 1998-2000 war. "The empty tubes are perfect for the coffee machines. Look, the bronze does not rust. And the shape is ideal." Using the burnt-out mortar shells as the inner barrel of his coffee makers, Azemeraw and his half dozen workers need about a week to make one sophisticated machine capable of turning out the dozen of so different types of coffee drunk in these parts. "We take these objects of war and turn them into objects of pleasure," says his son Mehany, 22, who works proudly beside his father. "Maybe, this is a message for the world." They pay about 350 Ethiopian birr ($40) for each mortar. Locals collect them from the barren border zone where a mass of munitions remain strewn from a conflict that killed 70,000 people in a territorial spat between the two Horn of Africa neighbors. The finished coffee maker sells for some 9,000-11,000 birr ($1,060-1,290), and Azemeraw moves about half-a-dozen a year. Most of the mortar shells are Russian-made, remnants of the Cold War arms trade. "Look at this quality," says Azemeraw, tapping a thick shell with appreciation.

    MIT Technology review magazine named a 32 yrs old Ethiopian scientist Dr. Solomon Assefa inventor of the year under 35 among other 35 inventors selected by the magazine. According to the MIT magazine Solomon Assefa selected for his invention of chips that communicate with pulses of light instead of electrical signals could lead to computers that are more power-efficient than today’s best machines and up to 1,000 times as fast. IBM researcher Solomon Assefa has brought this prospect a critical step closer.

    Gardiner Wilkinson, in his work on Egypt, has an engraving of an Ethiopian princess travelling through Upper Egypt in a chariot; a kind of umbrella fastened to a stout pole rises in the centre, bearing a close affinity to what are now termed chaise umbrellas.

    The earliest coffee was grown in Ethiopia, spreading from there co Yemen in southern Arabia, where the custom of roasting beans began around 1200 ad.

    Ancient Ethiopians were skilled stone masons building unusual structures and churches made from a single stone.

    It is also noted that computers represent numbers in binary and that many entry level computer books exemplify using a trick to convert decimal numbers to binary using a similar method as that of Ethiopian Multiplication. The Ancient Egyptians developed similar methods of multiplication,perhaps derived from the Ethiopians (note the proximity), however, their numbering system was more advanced. The ancient Egyptians used a base 10 system as does our modern one. Instead of writing 10 as 10 little slashes they derived a new symbol for 10 as well as for each successive power of 10; 100, 1000, 10000 etc.

    Some of the first stone tools, particularly certain kinds of knives, are known first from Ethiopian sites. Present-day Ethiopia is where coffee was first grown, and likely the home of the first beekeepers. Ethiopia is also the source of the Ethiopian Orthodox Church, a unique sort of Oriental Orthodox Christianity.

    To name few Israel leads the world in the number of scientists and technicians in the workforce, with 145 per 10,000, as opposed to 85 in the U. S., over 70 in Japan, and less than 60 in Germany. With over 25% of its work force employed in technical professions. Israel places first in this category as well. The cell phone was developed in Israel by Motorola, which has its largest development center in Israel. Most of the Windows NT operating system was developed by Microsoft-Israel. The Pentium MMX Chip technology was designed in Israel at Intel. Voice mail technology was developed in Israel. Both Microsoft and Cisco built their only R&D facilities outside the US in Israel. The AOL Instant Messenger was developed in 1996 by four young Israelis. A new acne treatment developed in Israel, the ClearLight device,produces a high-intensity, ultraviolet-light-free, narrow-band blue light that causes acne bacteria to self-destruct - all without damaging surroundings skin or tissue. An Israeli company was the first to develop and install a large-scale solar-powered and fully functional electricity generating plant, in southern California's Mojave desert." All the above while engaged in regular wars with an implacable enemy that seeks its destruction, and an economy continuously under strain by having to spend more per capita on its own protection than any other country on earth. This from a country just 55 years young having started off life on a very frontiers-like basis, whose population had mostly just emerged from the devastating World War II years.
