the russian war plane came down in an area of syria controlled by turk man rebels who shot at the pilots as they par chuted to the ground. who are they? they have lived in the region for hundreds of years dating back to the 11th century. estimates of how many turk men there are vary from one and a half million to three million. they were the first to take up arms. they look to turkey for support and protection. we spoke to a professor' university of michigan for turkey's motives for shooting down the plane. turkey would like to establish a sphere of influence inside syria, a no go zone where only turkey will execute power. the ethnic group which is related to the turks is part of that projected sphere of

influence. i think part of what's going on here is that turkey is now asserting its right to that sphere of influence in syria people living in crimea have been without a reliable power source for three days. electricity lines supplying the region from ukraine with blown up over the weekend emergency supplies are needed in crimea. people have had no power for days making it difficult to stay warm and to cook. >> translation: the problem is that the town has no gas supply. electric ovens are not working. that's why there are many requests for aid. >> reporter: russia and crimea, people here now have to rely on the russian government. >> translation: the situation is hard, but i want to say a big thank you to russia and the emergency ministry workers who came over. they are organising things very

ass as security forces across the continent grapple with groups taking attacks. there have been attacks in various areas. in northern kenya 148 people were killed, many of them were students. assailants target non-muslims, but muslims have complained of attacks. they border very close to telling people now we cannot live together any more and as a country, an as people, that we have no other place to go to. >> reporter: this is where the pope will celebrate his biggest attending. an estimated 200,000 people are expected on this ground for the special gathering. more in streets around here watching on big screens.

since albert einstein revolutionised our understanding of aggravate, light-- gravity, light and some time. he paved the way for technologies such as satellites and smart phones. our correspondent. >> reporter: einstein's theory of general relativity came 10 years after his more limited but now more famous e equals mc squared. it added the force of gravity to the equation and predicted how it can bend light and alter the passage of time. this has been widely observed by space micro scopes. more of the universe is full of dark matters. it will not be enough to produce that distortion. you need extra mass that you cannot see. that mass is called dark matter

and the dark matter comes because of einstein predicted this effect and thanks to that we can quantify how much dark matter there is in the universe. >> reporter: his equations are also the basis of global positioning technology found in smart phones and used widely for navigation. the einstein museum houses other technologies he help develop including this compass still used on ships. the equations presented by einstein in 1915 changed noefr our understanding of the physical world, from the effect of gravity on lights and the passing of time to the existence of black holes. it was also the beginning of a period that would see him become a super star, one of the most well-known theirs of the-- thinkers of the 20th century. einstein cam pained nuclear

weapons. those were topics which really moved many people automatic over the world and he had the crediblity, he had the pop star looks, also his personality. i don't think that he intended to be a pop star, but he really fitted perfectly well into this need for a pop star. >> reporter: einstein's theories also have a philosophical side, one he often expressed in the tens of thousands of personal letters he wrote. everybody realised that the things we do every single day are a permanent part of the universe from that moment on, i think people would treat everybody better and making sure that they were making a mark on the universe that they were proud of instead of embarrass them. >> reporter: einstein challenged that people try to

understand the things of the day. the important thing is to never stop questioning a quick reminder. you can keep amounted with all the news on our website. there it is on your screen. the address aljazeera.com. anytime you're 16 years old and say i'm better off dead than alive, that's how it is. >> no mother should ever have to bury their child. >> the caskets unfortunately are getting smaller and smaller. >> there are young people thirsty for change. >> can we fix this? >> yeah, we can. will we? welcome to a special edition of "america tonight." i'm sarah hoye.
