The Importance of Modern Technology by Milton Kazmeyer Modern technology has changed civilization in many different ways. Humans have almost always been on a path of progression, but thanks to technology, the twentieth and twenty-first centuries have seen a number of advancements that revolutionized the way people work, live and play.
Great achievements in science and technology in ancient Africa By Sydella Blatch Despite suffering through the horrific system of slavery, sharecropping and the Jim Crow era, early African-Americans made countless contributions to science and technology 1. This lineage and culture of achievement, though, emerged at least 40, years ago in Africa.
Unfortunately, few of us are aware of these accomplishments, as the history of Africa, beyond ancient Egypt, is seldom publicized. Sadly, the vast majority of discussions on the origins of science include only the Greeks, Romans and other whites. But in fact most of their discoveries came thousands of years after African developments.
While the remarkable black civilization in Egypt remains alluring, there was sophistication and impressive inventions throughout ancient sub-Saharan Africa as well.
There are just a handful of scholars in this area.
Here, I attempt to send an electrical impulse to this long-deadened nerve. I can only fly by this vast plane of achievements. Despite this, it still should be evident that the ancient people of Africa, like so many other ancients of the world, definitely had their genius.
Math Surely only a few of us know that many modern high-school-level concepts in mathematics first were developed in Africa, as was the first method of counting. More than 35, years ago, Egyptians scripted textbooks about math that included division and multiplication of fractions and geometric formulas to calculate the area and volume of shapes 3.
Distances and angles were calculated, algebraic equations were solved and mathematically based predictions were made of the size of floods of the Nile. Eight thousand years ago, people in present-day Zaire developed their own numeration system, as did Yoruba people in what is now Nigeria.
The Yoruba system was based on units of 20 instead of 10 and required an impressive amount of subtraction to identify different numbers. Scholars have lauded this system, as it required much abstract reasoning 4. Astronomy Several ancient African cultures birthed discoveries in astronomy.
Many of these are foundations on which we still rely, and some were so advanced that their mode of discovery still cannot be understood. Egyptians charted the movement of the sun and constellations and the cycles of the moon.
Clocks were made with moving water and sundial-like clocks were used 3. A structure known as the African Stonehenge in present-day Kenya constructed around B.
The Dogon people of Mali amassed a wealth of detailed astronomical observations 6. Many of their discoveries were so advanced that some modern scholars credit their discoveries instead to space aliens or unknown European travelers, even though the Dogon culture is steeped in ceremonial tradition centered on several space events.
Hundreds of years ago, they plotted orbits in this system accurately through the year 6. They knew this system contained a primary star and a secondary star now called Sirius B of immense density and not visible to the naked eye.
Metallurgy and tools Many advances in metallurgy and tool making were made across the entirety of ancient Africa. These include steam engines, metal chisels and saws, copper and iron tools and weapons, nails, glue, carbon steel and bronze weapons and art 27. Advances in Tanzania, Rwanda and Uganda between 1, and 2, years ago surpassed those of Europeans then and were astonishing to Europeans when they learned of them.
Architecture and engineering Various past African societies created sophisticated built environments. Of course, there are the engineering feats of the Egyptians: The largest of the pyramids covers 13 acres and is made of 2.
Later, in the 12th century and much farther south, there were hundreds of great cities in Zimbabwe and Mozambique. There, massive stone complexes were the hubs of cities.
One included a meter-long, 15,ton curved granite wall 9. The cities featured huge castlelike compounds with numerous rooms for specific tasks, such as iron-smithing.
In the 13th century, the empire of Mali boasted impressive cities, including Timbuktu, with grand palaces, mosques and universities 2.

Medicine Many treatments we use today were employed by several ancient peoples throughout Africa. Before the European invasion of Africa, medicine in what is now Egypt, Nigeria and South Africa, to name just a few places, was more advanced than medicine in Europe.
Some of these practices were the use of plants with salicylic acid for pain as in aspirinkaolin for diarrhea as in Kaopectateand extracts that were confirmed in the 20th century to kill Gram positive bacteria 2.
Other plants used had anticancer properties, caused abortion and treated malaria — and these have been shown to be as effective as many modern-day Western treatments. Furthermore, Africans discovered ouabain, capsicum, physostigmine and reserpine.
Medical procedures performed in ancient Africa before they were performed in Europe include vaccination, autopsy, limb traction and broken bone setting, bullet removal, brain surgery, skin grafting, filling of dental cavities, installation of false teeth, what is now known as Caesarean section, anesthesia and tissue cauterization 3.
In addition, African cultures preformed surgeries under antiseptic conditions universally when this concept was only emerging in Europe 2."Technology ultimately separates and alienates people more than it serves to bring them together." It is always a controversial issue whether technology separates and alienates people more than it serves to bring them together.

There is little doubt that technology impacts the world to a startling degree. For example, businesspeople around the globe use computers to perform work-related tasks. Some of the impacts of modern technology are positive, but others are not. Looking at a list of the advantages and disadvantages of.
Neo-Luddism or new Luddism is a philosophy opposing many forms of modern technology. The word Luddite is generally used as a derogatory term applied to people showing technophobic leanings.  The name is based on the historical legacy of the English Luddites, who were active between and Advances in speech recognition, wearable technology, and mobile apps have offered welcome improvements for many people who are disabled.
Yet while new technology is often praised for aiding. The communication technology is fast development in modern society. While many advocate that it is limitation of benefit to some people others argue otherwise.
