she was living in ceaser's villa.probably had their natural dhield with them, their son which means little ceaser and she was a very controversial figure. many romans despised her and thought he was the proof ceaser really wanted to be queen. afterall, his girl friend was the queen of egypt. >> what's the big lesson when you think of the assassination? >> i think the biggest lesson of the assassination is that politics always trumps military. you always need to have a political plan. it is not enough to fight people. both ceaser and the assassins were lacking any such plan. that's why he failed and the assassins planned. that's why the person that inherits it all is an 18-year-old kid that turns out wiser than either ceaser weor t great man who killed. he's the man who manages to put the pieces all back together again. it's not an easy process. >> it's absolutely fascinating. thank you so much. >> thank you. >> next on gps. what is the single best explanation for the rise of trump? an academic has a startling book tha

ceaser is, julius ceaser every day. [ laughter ] >> beware the ides of march. maybe that's what the kids are talking about at school today. you know what? you don't need to beware, but it's going to be slow. we have fog out and r there and low clouds. it's cool, man. these numbers, compared to yesterday, you know, on average, two to three degrees cooler. with the wind, it feels cooler still. wind chills in the 30s. just to drive home the point, it's cool to start, but warmer this afternoon. almost 10 degrees warmer. settling into the new sunrise, sunset time. 7:03 your sunset time. now, in the city, made up a little bit on the deficit, but still almost an inch and a quarter below normal. real quick update, pollen is a little better today, but it's going to bounce back tomorrow. not afternoon yet, you to get there. >>> kyla is in for alex to help. >> yes, we will get you there. trouble on the roads this morning and one of them has to do with the big water main break in hoboken yesterday. first street is closed in the vicinity of grand street and some better news

>> the jay ceaser hub is doing well. the first five year period ends at the end of 2017 so we will get into the the kind of reviews to talk about a potential extension. the hub is working both on grid scale and transportation batteries. on the transportation side, the principle activity is on lithium sulfur and they have made excellent progress. the goal is five times the energy density at one fifth of the cost. this is one of the areas, and there are others -- i love driverless vehicles as an interesting thing. but in these places, including storage, they are coming at us much faster than people thought. it is not always recognized. on the grid side, the main activity is on flow batteries where you use liquids instead of solid electrodes. another chemistry is magnesium and the opportunity to increase the energy density. i do want to emphasize in addition to that hub i think we have $225 million in various programs addressing energy storage. it is a game-changer. the costs have come down let's say for vehicle batteries b
