Don't Overlook Africa!
Because of the way flat maps distort the size of countries (the closer they are to the poles, the more distorted they are), most people don't really know just how big the African continent is. This leads many people - and the smart and powerful aren't immune to this - to underestimate Africa's importance. The map above shows just how wrong our perception can be (unless we've already seen a map like this before). It shows that you could fit the whole USA, China, India, Spain, France, Germany, the UK, Italy, Switzerland, Japan, and Eastern Europe, inside of Africa and still have some room left.
We're All Inter-Connected
Africa matters a lot because of the number of people who live there (about 1 billion as of 2005, with projections of 2 billion by 2050), but also because of the number of indigenous animal and plant species, because of the vast expanses of land that aren't being protected, because of the huge ecosystems that are uniquely found there, because of the impact that it can have on the global climate (especially deforestation and desertification), because of all the solar power potential and other natural resources, etc. It is one of the key regions that needs to improve on many levels for the welfare of its people and to safeguard the integrity of our planet's life-support systems.
Africa is too often the forgotten continent, but it shouldn't be, and humanitarian problems should make us forget environmental issues because both go hand in hand. The degradation of the environment will affect the most vulnerable people there.

Tunataka waichore upya ramani ya Afrika, waondoe Egypty, Libya, Tunisia, Algeria, Morocco, Madagascar pamoja na Sudan ya kaskazini,

pamoja!

Mkuu,

Umezisahau hizi?
Somalia, Zanzibar, Tanzania, Eritria,Djibouti, Mauritania, western sahara, Mali, Gambia. Chad, Niger na Nigeria.

watu wengine bwana!!??
mada poa , shomari unaanza kuichakachua.

mtoa mada anatoa changamoto kama Afrika nini nafasi yetu ukilinganisha na hizo nchi nyengine. badala ya kufikiria vipi tutajinasua na umaskini na kupata maendeleo ,unapendekeza waimege.. kumekucha.

Africa - tunazungumzia bara (continent) na si rangi ya watu wake, hivyo huwezi kuchora upya ramani ya Afrika kwa kuondoa nchi hizo!

Manataka nani awachoree?

The true true size of Africa

LAST month Kai Krause, a computer-graphics guru, caused a stir with a map entitled "The True Size of Africa", which showed the outlines of other countries crammed into the outline of the African continent. His aim was to make "a small contribution in the fight against rampant Immappancy"-in particular, the fact that most people do not realise how much the ubiquitous Mercator projection distorts the relative sizes of countries.
A sphere cannot be represented on a flat plane without distortion, which means all map projections distort in one way or another. Some projections show areas accurately but distort distances or scales, for example; others preserve the shapes of countries but misrepresent their areas. You can read all the gory details on Wikipedia.
Gerardus Mercator's projection, published in 1569, was immediately useful because it depicts a line of constant bearing as a straight line, which is handy for marine navigation. The drawback is that it distorts the shapes and areas of large land masses, and the distortion gets progressively worse as you get closer to the poles. (Africa looks about the same size as Greenland under the Mercator projection, for example, even though it is in fact 14 times bigger.) This was not a big problem for 16th-century sailors, of course, and the Mercator projection remains popular to this day.
In Mr Krause's map (above) he seems to have used the shapes of the countries from a Mercator projection, but has scaled up the outline of Africa, without changing its shape, to show the appropriate area. An alternative and arguably more rigorous approach would be to repeat the exercise using an "equal area" projection that shows the countries' areas correctly while minimising shape distortion. These two properties are the hardest to balance when showing the whole world on one map. I decided to rework Mr Krause's map using Gall's Stereographic Cylindrical Projection (1855) with two standard parallels at 45°N and 45°S. Distortions are still evident at the poles, but for most countries shape is maintained, and their areas are shown correctly. As you can see (below), the results are distinct from Mr Krause's map. But however you look at it, his point is a good one: Africa is much bigger than it looks on most maps.


MY QUESTIONS:

HOW MANY TIMES TANZANIA IS BIGGER THAN KENYA ?
HOW TANZANIA WILL APPEAR IN THE REAL MAP COMPARED TO SOME NEIGHBOR COUNTRIES (EAC) ?
