It is unfortunate that most people -- even modern Africans -- are unaware of the ancient achievements that came out of Africa.

Many of the modern high-school level concepts in mathematics were first developed in Africa -- as was the first method of counting. These concepts include division and multiplication of fractions and geometric formulas to calculate the area and volume of shapes. They also invented mathematical methods for measuring distances and the use of angles -- including dividing a circle into 360 degrees and an early estimate of pi.

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.

This is just in the area of mathematics. 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. They divided the year into 12 parts and developed a yearlong calendar system containing 365 ¼ days. Clocks were made with moving water and sundial-like clocks were used.

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.

Advances in Tanzania, Rwanda and Uganda between 1,500 and 2,000 years ago surpassed those of Europeans then and were astonishing to Europeans when they learned of them. Ancient Tanzanian furnaces could reach 1,800C — 200 to 400C warmer than those of the Romans.

There are plenty of other examples in areas such as architecture, engineering, medicine and navigation.

Maybe so, say scientists who last year launched a new type of Search for Extraterrestrial Intelligence, or SETI, project to eavesdrop on aliens. Using data collected by NASA’s Kepler space telescope, a team of scientists spent 36 hours listening in when planets in targeted solar systems lined up, relative to Earth’s perspective, in hopes of detecting alien interplanetary radio signals. “We think the right strategy in SETI is a variety of strategies. It’s really hard to predict what other civilizations might be doing,” Dan Werthimer, director of SETI research at the University of California Berkeley, told Discovery News. So far the search hasn't turned up any artificial signals yet, but this marks a change in strategy for radio searches for ETI with Kepler data taking a focused lead."

szotz (2505808) writes "There's a lot of skepticism swirling around NASA's plan to send humans to Mars in the 2030's, not to mention all those private missions. If we want to have sustainable (read: not bank-breaking) space exploration, the argument goes, there's no way we can do it the way we've been going to the moon and low-Earth orbit. We have to find a way to exploit space resources and cut down on the amount of stuff we need to launch from Earth. That's not a new idea. But this article in IEEE Spectrum suggests research on resource extraction and fabrication in low and zero gravity might actually be making progress...and that we could take these technologies quite far if we get our act together."

Unless something has changed recently, there is no such as Catholic divorce. In order to separate as a couple, the marriage has to be annulled, which is usually accomplished by establishing the one or the other or both parties were unfit to enter into such an agreement at the time of the marriage.

I, for one, completely agree with you. There are good, useful frameworks out there -- at least in the Java world.

I use Hibernate because it is very flexible and does the heavy lifting with regards to ORM and caching. Do I use it because I am lazy? No, I have written database access code in C, C++ as well as early Java. I use it because it frees me up to focus on the business logic of the application

I also, highly recommend using Spring. The power and flexibility of dependency injection alone is worth it.

Again, Maven is an invaluable framework.
