here's the waterline. when i take the metal out and throw it overboard, overboard, will this water level go up, will it go down or will it stay right there? the thing to think about is now the metal is made to float. when i take it and throw it overboard, then the metal sinks. any difference in the buoyant force on the metal either way? something to think about. question without giving away too much information. well, if the water was all the way to the top and there was an ice cube inside, there's ice cubes floating, if the ice cube melt, would the water overflow? that's a good point. how about that, gang? you've got a glass of water with an ice cube in it. the ice cube sticks up a little bit, yeah? when the ice cube melts, does the water level go higher, lower or stay the same? - higher. - it's higher. i'll be asking you that question at a different time. [laughter] too bad it's-- yeah. i got a nice one for you. you want a dandy? this is a dandy. okay. here's your question, gang. consider a balloon float

notice how much-- notice how far down-- how far up the waterline is on the wood. that's because the whole weight of this is pushing down, yeah? well, this push down is hard when it's submerged? won't it buoyed up itself? yes. if you applied buoyant force on it. notice that the wood is a little higher now? yeah. but notice the water level over here is the same. there's a lot to think about there, gang, a lot. and what i wanna do is i want to give you a couple of homework problems. problems, exercises, okay, that will help you shape up

because very often on this set, in this series, we call them iceberg companies - they're below the waterlinevery important. if you take them away, everything changes, but you don't realize it. mckesson does have a public persona, and i think it's growing, but let's start with that. what does it do? - mckesson today, i would tell you, is a healthcare solutions provider in canada. my experience with the company - i've been with the company now a little over 10 years, and i think if you were to look at us 10 years ago, for those of us in the industry would have identified us as a wholesale distribution company. we picked, packed, and shipped boxes to several pharmacies across the country. five years later, i would tell you we became a company that started to diversify in some complementary services, whether that was technology or other assets that supported wholesale distribution. and today, i would tell you we're in a variety of different healthcare solutions, touching directly the patient, dealing with providers. so, we have become quite a diversified portfolio of healthcare service offerings

mosher: i'm working on a pubc art project called the high waterline project, and for the project i'm drawing the 10-foot-above-sea-level line around the eire coast of brooklyn and lower manhattan, so it's almost 70 miles that i'm covering. and the point of the project is to get out into thcommunities that are gonna be affect by tha and give them a visual idea of what that means -- what the 10-foot-above-sea-level line means and also give them the tools to do something about that. so, along my way i'm handing out action packets that give people tips on how to live more sustainably. a really important part of my project is the whole human element. i think a lot of times they don't know, "okay, climate change -- first of all, what does that mean? and then what do i do about it?" so, you have the media scaring you into thinking, climate change -- we just can't do anything about it. we should all panic and run away to higher ground. but there are things we can do about it. so, it's nice to be able to get out and talk to people. and i've found that no matter what background, no mter where

the waterline is behind me. you can see it on this green building.was 8 feet high in sea bright, three blocks wide. ocean is here, the river is here and the water came crashing in like a thunderclap in on this town. all of the businesses were destroyed here. now the mayor says 70% of the people and homes are back. 400 families are still displaced. you're seeing that a lot up and down the jersey shore and new york. people displaced from their homes, trying to figure out a way to either tear down their homes still standing, gutted the way they were after the storm or rebuilding empty lots. unfortunately it's scattered. the progress in some areas is great. in other areas could be right next door, it's completely stagnant. we do have businesses open down here. sea bright is emblem atic of wht you're seeing up and down the shore. >> thanks. >>> campaign gubernatorial candidate and hard line conservative ken cuccinelli tried to claim reproductive choice and scientific choices could lead to eugenics. he did that by invoking gattica. >> dna plays the primary

the line across it, 8 feet high, that's the waterline. that's three feet higher than my head. that's how the water got in this town and doesn't include waves crashing over. the reason it got hit so hard, this town is three blocks wide, the river is down there, the ocean is right there. when the storm hit, the water came crashing in on itself and destroyed everything in its path. businesses all along here looked as if they had gone through a spin cycle. everything inside of it was thrown upside down. this, that, and the other completely torn apart. a lot of them unfortunately are boarded up. there is signs of progress here. we had this hardware store open for over 100 years. they were able to rebuild. unfortunately not with grant money. they had to take out more loans. they are waiting and hoping their grant money does eventually get approved. sea bright is one of many. towns up and down the jersey shore. you're seeing much of the same over in new york city as well. breezy point completely decimated, burned to the ground in new york and on the rockaway peninsula. that is starti
