now let´s have some conspiracy theories related to this topic.

after french revolution late in 18th century, nationalistic ideas were widespread all over europe and most parts of the world. as a result of this many non-nationalistic empires disappeared.

It was not coincidence that "young turks" (Les Jeunes Turcs, jön türkler) had found their perfect place in france. young turks were famous for their nationalistic ideas. they did their job perfectly and destroyed a six century years old empire less than fifteen years.

lets jump to present.

it is not coincidence that nationalistic kurdish people which involved terrorist activities have found their perfect place, again in france. of cource also other sisters of france are helping them such as belgium, germany, denmark... etc.

this year american embassy in ankara had a suicide bomber and one security guard was killded one news reporter lost her one eye. that bomber was checked by german police in germany and after he show his french passport, german police let him free. just an example but not coincidence of course, thousands of french passported...

anyway.

nationalistic ideas did their job well for the last two centuries and these ideas are being replaced something else now all over the world. globalisation, one world goverment, one electronic money...  easy to take control small nation based countries compared to big empires. long live multinationalism, death to nationalism! obey the rulers of new world order!...

it costed two world wars bringing nationalism and i guess i will cost two world wars to sweep it away. get ready!

here is the english translations:

Türkiye Cumhuriyeti: Turkish Republic (abbreviation: T.C. or with one point T.C)
This officially indicates that it belongs to Turkish state, property of turkish state.

Türkiye Cumhuriyet: Turkey, Republic (something has names turkey and republic in it.)

If they really want to protest something they should put T.C. on the beginning of Merkez Bankası. Whenever i mention this i am being stricly cencored. Online news sites have comment option for their readers but none of them yet accepted this kind of comment even the news about merkez bankası. maybe they were all invaded!

anyway, Türkiye Cumhuriyet Merkez Bankası is the long form written on all paper money. But you cannot put T.C. here because T.C. stands for Türkiye Cumhuriyeti. Our central bank is a private bank from the beginning and millions of people get fooled by using Türkiye Cumhuriyet.

I hope this message will not be cencored here, too. Otherwise i will think TC (this time turkish class ) was invaded, too.

bu/bunlar: it is/they are close to you, you can reach it grab it and hold it in your hands...

şu/şunlar: it is/ they are close to you but not close so much, you have to take some steps to reach it.

o/onlar: it is/ they are not close to you. you have to walk/travel some distance to reach them. the distance equal or more that the people you are pointing cant hear you when you speak out loud.

it is considered to be rude to talk about some respectful people "bu" or pointing a finger to them when you use "şu". so if you have to do that always add a good adjective. for example: "bu arkadaş", "şu arkadaşlar"

Why don we build our own tablet instead of inviting big companies. they never come unless they make huge profit. You can build your own stuff with that profit part. The project expected to based on open source software, so you can make any chinese technology company produce your tablets as you wish if you dont want to produce yourself. 

BTW, tablets and other technological stuffs are not something magical to solve educational problems, they are just dumb tools. If your education system sucks, even the best technology in the world become useless...

"vız" is supposed to be the sound of a mosquito or any fly making sound. emphasising that it is as important or easy as a mosquito´s sound, in other words not important, very easy, not a big deal, even doesnt worth to think about it...
