coming out of blackboard, okay? the--what takes on the distance? divide by the time, i got it. let's take a distance of one wavelength. that's the distance to go from here to here or from here to here or from here to here. if i know the time that goes by during the time a wave goes one wavelength, then i can put that in here and i can have the wave speed. if i were interested in things like that, then we kind of are, aren't we? and what is the time it takes for a wave to go one-- whole cycle? what do we call that time? begins with the p. - period. - period. okay? and so all over here, we can say wavelength over the period of the wave will give you the speed of the wave. but the period of the wave can be re-written, one over the frequency. and those of you who are a little bit into mathematics know that this is equivalent to-- all right, let me write it this way. and so we have a relationship for the speed of any kind of waves, gang. and it simply is the velocity of the wave, the velocity over the speed, speed is the magnitude of velocity. that velocity of the wave is simply gon

has to be looked at holistically and i wish i luck and certainly that you can ranger for a clean blackboard and is we if we can't agree on what could happen and it's easy to bring up the politics we can't do this because of those people and those people don't like it. let's see if we can agree that on a plan of what is necessary in my prospective and you're headed that way you're thinking in the big terms that the city of san francisco is known for and really needs to continue >> thank you director edward reiskin. >> first of all, i want to thank john ram and his staff for bringing this forward. josh stated elegantly why this work is important to the tjpa project and the city and the whole region i think it's really of critical importance. as the director harper said this is our adolescence we need to continue this afford we would be neglect if we didn't seek answers like director martin luther said we need to find opportunity as a result of this work we would be neglected if we didn't and place the land the trains we're spending 4 to $5 million to land the trains at the transbay center tha

remembers the pain of having to leave school in the seventh grade because she couldn't see the blackboardtime he was five, severe cataracts blinded marcus as well. how did your parents explain your blindness to you? >> roberts: they really didn't explain it. they just taught you how to do stuff for yourself. that was the main thing. >> marsalis: marcus told me that you were never about self-pity or feeling bad about yourself. >> coretta roberts: oh, no, no. ( laughs ) i got adjusted to it and accepted it as it was god's will. >> roberts: she showed you by example. i mean, she could do a lot of stuff that to this day i can't really do. like, she can iron clothes, she can cook, she knows how to, like, run a household. >> marsalis: he taught himself enough to get his first gig at the silas missionary baptist church, on this very piano. it's out of tune but still quite soulful. ♪ ♪ >> sister murray: i remember him. >> marsalis: sister murray used to lift marcus up on the piano bench. his mama said, when he first started playing, he didn't sound good. >> murray: ooh. he got better. he could re

soon as we hit that limit from we are going to have to go back to book reading and black port -- blackboards again. ast: james in new hampshire, parent. hi, james. caller: i appreciate the opportunity to speak. i think people on the show that that the tests aren't effective anymore, that is probably not the case. the history of this is that back in the beginning, they had to have a way to judge the quality for the student coming in -- back in the 30's or so, -- back in the 1930's or so, the president of harvard university was involved. it is absolutely necessary that they have a way of judging the relative merits of students coming in and so far as secondary education was not equal in the u.s. that is a very unjust test in many ways because secondary education is not equal cross the u.s. students long before they take the tests are on a footing that is not equal. host: all right, james. host: we are getting your thoughts on changes to the sat. in 2016. take place want to know your experience with the test, but first -- we will keep taking your phone calls, but first we wanted show you what h

you might tell them about the blackboards on friday., friday. >> we do actually collect from our students, not just lip service but collect the stories. it's called lessons from the field about how they're applying the learning and what they're realizing in their workplaces. we're getting tons of stories from our students. this is affecting me immediately, that's really different in this space. >> that's great. >> andrea, thank you for joining us today. >> thank you very much. >> thanks for coming in. >> you can drunk at home. you don't have to drive. thank you. >> thank you. >>> coming up, jobless claims data. later, a cloud based company disrupting the world of business management. meet the ceo of execute to win. find out if it can help your business.
