this piece of iron, very, very dense. i'm gonna put the iron in the water. yacko, it sinks. hoom, really sinks. some people say, "well, that's because there's no buoyant force acting on it," and you say-- there is. there is or isn't? there is. answer begins with i. is. is. okay. you like that hint? okay. turns out there is. how about this piece of wood? this piece of wood have the same size, has the same volume. i'm gonna put that in. he was, like, "oh, there's a buoyant force acting on the wood." yeah. it's true. some people would say, "the fact that the iron sinks "and the wood floats is evidence that there is more buoyant force on the wood." to that, you would agree or you would disagree? knowing they're the same volume. see what your neighbor says. which has the greater buoyant force, the sunk iron or the floating wood? and realize they're both the same size, same volume. how many say there was a buoyant force on each, and son of a gun, the buoyant force was greater on the submerged iron? some people say that, but some people don't. now, let's use archimedes' principle t

the iron is dry brush. this if you submerge this in water, it's going to destabilize the iron and it's going to begin to corrode at a more rapid rate. the items that are many diagnostic, iron items are more tig nostic, we actually conserve. this appears to be part of a -- maybe a blade for cutting grass. this is the blade portion. it's just corroded away in this area. but if we didn't conserve these items, what would eventually happen to them is being out of the ground, they'd veeventually fall apart. we put them in these conservation tanks where we run currents. it sloughs the rust off it until you get down to the bare metal.

the australia, dollar fell after b hchlt pch bhp warned of flatter iron ore. and foreign markets sensitive to any hints. but the world's biggest miner says that china's pull back is not stopping it from forging ahead with its ambitious $10 billion production plans. rifle rio tinto says it's also stepping up production while keeping an eye on chinese demand. let's talk more on what the picture may look like. we have patrick hills joining us. bhp saying china is seeing softening demand. if nand but rio tinto seems to be taking on a more resilient view. put some con test into where you think it's heading. >> i think that the market for iron ore remains incredibly positive. i think the comments today made by ian ashby maybe were taken out of context. because his view was that the market will remain very strong to 2025 and i think they're going to continue to invest. i think they continue to look at their capital programs as does rio tinto and do all of the miners. but i think the supply demand fundamentals would suggest that investing in iron ore right now is exac

donelson it would take $1 million to build this prop, iron-clad gun boat. iron-clad, holy smoke. it's not like the delta queen. big, fat, ugly, cannons pointing out and meant for business. the iron-clad technology isn't all that new. they were used as floating batteries and some steam powered. here in the united states, certainly in the 1860s, they were pretty cutting edge. technology had been there all along. iron plate, that's been around for a long time. cannon, certainly. steam power for boats, that's great. these molded them all together. that technology. and the technology was such that you could take a gun boat and for the first time, take a gun boat a take on land forte fiction. ft. henry is a good example. those same gun boats did the same thing at donelson, got their butts kicked. what's neat is that the technology is there. and with that technology you have general grant, an army general, he has to play with the navy, vice versa. the navy is part of the game now out here in inland waters. that's brand new also. you have flag officer foote, later admiral, was in charge

this huge iron ore flattening of demand and a concomitant decline in steel production. is china really slowing more noticeably? is there a more rapid decline? something that will take their economy from 12% growth to 0%. we'll know more later in the show, when we speak to one of the greatest miners of earth, but suffice it to say, that bhp lowers the boom, the china plays are about to get poleaxed, and which companies are china first? we have to break out the china stock book, right? oh, look at this. under the self-reliance and arduous struggle segment is joy global. yeah. that's a coal mining equipment maker. china is slowing. they won't need all that coal digging machinery. their opening coal play is about one hour -- that's every nanosecond there. that is a real great leap forward for the oxygen. joy goes down $3.44. of course, coal itself is a china hand, so peabody, the big dad coal company got slaughtered. gave up $1.80, but, you know, that is 5.4%. sure enough, under the investigation study section of quotations from the chairman mao, we find peabody. all right.

part of an iron padlock. this is the body of the padlock. this is the bail. this is the hinge right there and it would swing back and forth and the key would enter right there. and then we found four navy buttons. these two are officers' buttons. but these date to the late 1820s, early 1830s. we're not sure why they're in the slave quarter, but it's a mystery that needs to be solved. this is part of a pharmaceutical vial right here. and most interestingly, we recovered just this past week we recovered what is a real or a spanish coin that dates to 1801. and what's interesting about this coin is oit clip it's clip. there are little pieces taken out here. that's actually an illegal practice by sommmere merchants. it's some direct evidence that slaves are engaged in marketing activities. they were, you know, selling items to either the madisons to their guests or neighboring slave owners or neighboring community members to obtain cash or barter to obtain some of the items you see right here. some of the other items we've got evidence for, you know, the kind of f

you're in iron mount... jessie's hamburger stand. in iron mount... the, uh... the sundowner motel. it's a gray delta 88 oldsmobile with massachusetts license plates. would you please send a tow truck?

( sighs ) guess i'll need a place to stay tonight. are there any motels around here? only place that's open out here is the star lite lodge. follow me, i go right by it. rebecca: lots of trucks. i hope they have a room. alberto: yeah. what are you doing? getting my suitcase. are you going to stay here, too? where else am i going to stay? let's get out of the rain, huh? thanks. how you doing? hello. just one second, please... scratch card, today could be my lucky day! never any good luck here when it rains. do you have any rooms available? hey, you're the lucky couple. i just had a cancellation. you and the mrs. can have that

do you think that is what is behind the iron-ore companies, the mining companies? >> first of all, great to see you. our man from london. >> i like this new set. >> you like it? isn't this great? we're on the floor and it's great to have you. but to answer your question, i'm suspicious about this. now, this poor guy makes a comment that iron ore ships into china are going into the single digits. you would have thought china was collapsing in the world markets. all of the material stocks, worldwide was down, china was down. good heavens, look, it's very simple. chinese steel -- the question is steel. the steel numbers of china are getting actually a bit better. they were slow last year. here's what morgan stanley said. the chinese markets are improving. mills are raising prices. steel production is up month over month in february. they are simply pointing out that some of the demand is slower. it had 24% growth in imports, in iron ore for the last ten years in china. you can't grow 24. it's going to slow down a little bit. i think this is a little overblown and peop

it was the era of the iron rice bowl.nder the planned economy, state-owned enterprises were assigned workers, whether they needed them or not, and workers were assured lifetime employment and pensions, regardless of factory output. but factories were often poorly run, sometimes by people with strong party controls and contacts, but who lacked technical or managerial skills. ultimately, central investment dried up. the factories went into debt, and today many state-owned enrprises limp along with a redundant work force, outmoded equipment, poor management, and an outdated production system. man: this is really what we refer to as china's rust belt, and it's the equivalent of cities like pittsburgh or cleveland, say, 20 years ago in the united states. in fact, the northeast, we could argue, has been receiving huge subsidies from the central state all these years and has mismanaged those subsidies. so they had it coming to them, just as in a sense, one could argue, the u.s. automobile industry in the 1970s had gotten too fat

also edamame, lentils, starchy beans and tofu have iron as well. when you eat the vegetarian sources they are not as absorbable as the animal proteins. couple them with a food rich in vitamin c because c helps to boost the absorption within your body. when you eat your spinach and kale, drizzle some fresh lemon juice on top. the lemon juice brings vitamin c to the table to bump up the iron in your body. >> thanks for your question. >> good luck. >> now to sharon in texas on the line joining us live. good morning. what's your question? hello, sharon? i think we may have lost sharon. let's go to our viewer e-mail. this one coming from emily in north carolina. emily writing, i'm a graduate student with a busy schedule and a tight budget. i found out this summer i have celiac disease. what are delicious gluten-free meals that are cheap and quick? i'm sick of rice and beans. >> good question. you can pretty much eat anything that you would normally eat if you were eaten gluten. sandwiches, cereals. hit a large grocery store or health food shop and buy a

iron dry brushed, if you sub merge this in water it will destablize the iron and corrode at a more rapid rate. the items more diagnostic, we actually conserve. this appears to be part of a maybe a five blade for cutting glass, and this is the blade portion and corroded away in this area. if we didn't conserve these items what would happen to being in the ground they -- the rust would axler rails and they would foul apart. we put them in conservation tanks, run electric current through a solution of baking soda and sloughs all the rust off it. until you get to the bare metal. next is to use a drummel tool to clean up the remaining rust and washed in a solution of disstilled water, boiled and disstilled water, bike in the oven to dry it and dipped in acetone, then coated with a conservation coating to keep the objection he general off the object. some of the iron objects potentially here on an 18th century site were made here on the property. we could have objects such as a hinge made by a slave name moses. these were objects that tell much larger story about what they were but about the p

tim ewert, itv news. >> we've got the extensive coverage of ironing.end the top ranked r-rated comedy makes a comeback. while no other movie debuting nationwide, 21 jump street starring jonah hill and shannon tatum is looking to regain the raunchy box office mojo that r rated come disenjoyed last summer. they think it will muscle out ""the lorax"" with at least $30 million. speaking of r rated comedy success, there's been lots of talk about the overbudgeted, underperforming john carter, there's been less notice for "project x." it's a party flick that cost 12 million to make. it should finish in the top five this weekend passing $60 million in earnings. >>> finally, russell brand turned himself in yesterday to new orleans police to face the music for grabbing a photographer's phone monday and throwing it through a nearby window. in a tweet brand joked he did it as a tribute saying, quote, since steve jobs died i cannot bear to see anyone use an iphone irrev very recently. that's sort of -- need a little bit of class there. people need to edit their twe

the iron clad technology is not all that new. but here in the united states, certainly in the 1860s, they were pretty cutting edge. technology had been there all along. iron plate, that's been around for a while. cannons, certainly their steam power for boats. these molded them all together, that technology. and the technology was such that you could take the gun boat and really for the first time take a gun boat and take on a land fortification and with some measure of success. fort henry is a good example. the same gunboats did the same thing here at donelson and got their butts kicked. but what is neat is that the technology is there. and with that technology, for instance, you have general grant who is an army general. he has to play with the navy and vice versa. the navy is part of the game out here in the inland waters. that's brand new also. so you have flag officer foot, later admiral, was in charge of the union gumbo fleet. and grant and foot, fortunately, had a great partnership with this. so, again, the study of fort d

some of the shipping companies like xl, iron ore, eagle dropped dramatically. the markets had negative reactions overall. we saw transportation companies down, iron ore companies down and materials around the world dropped. i think it's a bit of an overreaction given what is going on with the overall markets. >> bhp down, arch coal as well, the coal company, steel companies across the board. i should point out fex -- >> coal shipments, iron ore shipments affect transportation stocks. all of the rail roads went to the downside today. >> bob pisani, thank you. oracle reported earnings of 62 cents a share. the stock is rallying. jon fortt is here with me. what do you have, jon? >> in a way is shows how short the expectations were. the revenue came in slightly light based on what the consensus was looking for. licensing revenue was $2.4 billion. that's the most important number. the street was looking for a range of 2.21 to 2.44. that's the range oracle gave. a lot of people thought it would be on the low end. hardware revenue, though, was a mix at $869. the range

also iron is another problem because meat is an excellent source of iron. when you eliminate lean meats from the diet, you're eliminating a very good source of iron. not that you can't be well nourished. you can as a vegetarian. it's just that people need to pay some attention. they need to choose foods more carefully. disease prevention through nutrition is a relatively new area of research that explores the link between certain foods and the nutrients in them and their ability to prevent or minimize a long list of medical conditions including heart disease, high blood pressure, and cancer. for example, researchers have found a correlation between foods which contain phytochemicals and antioxidants and the slowing of normal wear and tear of the body. joanne ikeda: phytochemicals and antioxidants reduce oxidation, oxidative damage to cellular tissue. and that's involved not only in the aging process but also in carcinogenesis where cells become weak. they, of course become-- they mutate, and you get cancer cells. these substances are found primarily in frui

they're not cutting back expansion of their iron ore. they're expanding their iron ore facility.comment on caterpillar. late headlines. global sales up 20% for the three months ending february. i don't know if you know this or not. but i don't know if that includes the bucyrus acquisition. this is a headline from that. i'd like to know if we're really talking about apples to apples here. >> great point. >> caterpillar's revenues went through the roof in the last few years. they had an absolutely unbelievable two or three years. from 2010 to 2011 their revenues grew 40%. 40%. so bear that in mind when you see numbers that say -- it sounds really good. keep it into context. >> bob, i do think that those numbers do include it. there's also some chatter here just so you know about dealer sales show strong but slowing growth. obviously when you have a strong stock like caterpillar, anything that is deviating from the notion that earnings per share have to go higher, goldman sachs said they expect estimates -- earnings to be 10% higher than estimates. you're going to have a little bit

iron plate. that's been around for awhile. cannons certainly there, steam power for boats, that's great. but these molded them all together, that technology. and the technology was such that you could take a gun boat and really for the first time take a gun boat and take on a land fortification and with some measure of success. fort henry is a good example. fort donelson is not a good example. because those same gun boats did the same thing at fort donelson got their butts kicked. but what's neat is that the technology is there. then with that technology, for instance you had general grant who's an army general, he has to play with the navy and vice versa. the navy is part of the game now out here in the inland waters. that's brand-new also. so you have flag officer-fo off foote was in charge of the gun boat fleet. grant fortunately had a great partnership with this. they were in full agreement. so again, the study of fort donelson, man, we're losing something here if we're not doing it. is looking at the first real joint oper

iron dome is but one layer. one layer in a comprehensive multi-layer rocket and missile defense system that is being built as a result of close united states and israeli partnerships. we are proceeding to implement medium range missile defense with david sling and upper tier ballistic defense, with the arrow three system. we are also working to upgrade israel's patriot missile system and batteries. we are committed to moving forward with all of these sys m systems and more. because as the prime minister told me, and i agree, these missile shields do not start wars, they prevent wars. [ applause ] supporting israel's missile defense is important because it saves israeli lives. beyond missile defense we must also ensure israel's quality military edge by equipping them with high advanced weapons that are restricted only to the closest of our allies and partners. as an example, the united states will ensure that israel continues to enjoy unquestioned air superiority by delivering to israel the advanced fifth generat

there's the iron crane, and smaller red oven there. having a kitch especially on the first floor of a slave quarters large enough to serve the entire household was typical of an urban slave quarters near or attached to the property owner's residence. you know, in looking at a building as a primary source, i'm always interested in the wear patterns. and that's the evidence of how human beings habitually impacted a building and left their marks on it. orlando ridow, a member of a teamworking to study and document this building, has identified these wear patterns. see that slanted pattern? identified those patterns as the marks left by the sharpening of a knife there on the edge of the original firebox. while the people that made these marks are gone, largely unrecorded by documents, the evidence of their labor at an elemental, essential, and timeless task, sharpening of a blade, remains. now, who might have made these marks? it could have been charlotte dupuis or others in the van buren household if this was built in the 1820s, or it cou

and, ironically, often people who are displaced by dams or who are impacted in some way in the ruraleas will not see the benefits in terms of electricity. narrator: displacement of people living in areas targeted for dam construction is only one fact of hydroelectric development, whether privately or publicly funded. fox: all around the world, tens of millions of people have been displaced by large-scale dams. in laos, it does disproportionately impact ethnic minorities who live in the highland areas where the dams are being built. so they're resettled away from the reservoir areas and they're also resettled away from the mountains and highlands above reservoirs. narrator: anotr problem with resettlement in laos isacy ofheamarosasaughssas.smbed x: 1.9 million ns oorance e droedn , so when people are resettled for example from a highland area where they practice shifting cultivation to a midland or a lowland area where they must grow wet rice or some other unfamiliar crop, not only might they be exposed to unexploded ordnance, but if people need to sulement their food source or their

ever be reaching there with your re hand and grabbed the iron pan? if you ever had, you can show that today, you'd be tattooed, all right? you're gonna burn yourself. isn't that right? but could you reach into that oven and grab a pan if it had a wooden handle and grab it momentarily? you can do that. you can do that. you know why? because t--that wood is hot. that's the same temperature as the metal. but not very much energy is gonna conduct from the wo to your hand, so you can safely hold it. you can do that. ever see these people walking at hot coals after they've paid more than $300 for some sort of a course that teaches you how to have self-confidence in yourself? and then the test of that self-confidence is they say, "we are gonna violate the laws of physics "and show you that mind over matter. "that $300 you've spent for that 15-minute session "is gonna pay off ecause wre gonna apply those techniques "and we' gonna show that you can walk with bare feet on hot coals." and so the people do that. they take off their shoes, bare feet, they step on

once again had taken a page out of playbook of the democratic party in nominating a war hero rather ironic since they nominated a war hero from a war that they had opposed pretty vociferously, that was zachary tayl taylor, we have a poster with taylor and fillmore. the wigs managed to win to defeat the democratic party candidate, the democrats hurt very badly by internal divisions especially within new york state really serious battle within new york state had new york gone a different direction, the democratic nominee might have been nominated instead of zachary taylor, the wig nominee, but series divisions within the party, i think i may have talked about it before, a lot of factionalism within the democrats in new york, different elements, the so-called hunker group and so-called barn burner group. we won't get into that but suffice to say the wigs again end up with a successful candidate with electing a president in the form of zachary taylor, but ironically again someone who's not really a committed wig. someone who is less than a die-hard wig, you know, in the clay or webster mold, t

, there's the iron crane and the smaller red oven there. having a kitchen on the first floor of a slave quarters was typical of an urban slave quarters located near or attached to the property owner's residence. i'm always interested in the wear patterns and that's the evidence of how individuals impacted a building and left their marks on it. the american historic trust, identify they'd wear patterns right here as the marks left by the of the original fire box. while the people who made these marks are gone, largely unrecorded by documents, the evidence of their labor at an elemental, essential and timeless task, the sharpening of a blade, remains. now, who might have made these marks? it could have been charlotte or others in the van buren household if this structure was built by the 1820s. or it could have been one of the enslaved people listed in the 1844 inventory. here you see the transcription of the final entries in that inventory listing those identified as slaves for life, along with their ages and assessed monetary value. as you

it was a wooden rail with a little thin layer of iron on the top. so you overburden those lines with heavier rolling stock now carrying three, four, five times as much as they're designed to carry and they'll break down, too. so yes, not only did the blockade interrupt international trade, it interrupted internal trade as well because of the impact that it had on southern railroads. you're absolutely correct. one more? we're out of time now. i'm sorry. we have to stop. i'll be glad to talk to anybody that wants to out in the foyer. thank you for your attention. i appreciate it. >>> all right. i think we'll go ahead and get started here. so if you want to find yourself a good seat, we will begin this next. it's a very brief section. but dave alberg has something really important to say and he's brought lisa stansbury with him to help him out. i think some of you may have met a couple of new faces here at the mariners' museum. they're up in the lobby. and that's who dave alberg is here to talk about. i've known dave for i'm not sure how many years now

the iron-clads ran the batteries and then the union army got behind the fort. nothing there to stop them. so fort henry, fort donelson set off that chain reaction is that columbus essentially because fort henry did fell right behind it. yes, sir. >> the location of fort henry? was it not doomed from the way it was set up? >> it was doomed right off the bat. the location of fort henry was built at kirkman's old landing. i don't know why they built it there. a number of gentlemen, captain taylor was probably the most colorful -- well, the people found problems with it. the fort was started in the summer of 1861 when the river was low. low water. and the fort did have a great field of fire. for three uninterrupted miles, you could shoot cannon three miles. and that's pretty good. but they didn't take into account the river floods. and the captain taylor was an artillery man who came out from nashville to teach the guys how to shoot the big guns. and during one of his afternoon walks he's up above the hills around the fort and kind of noticing these mud rings up on

then the executive of bhp says iron ore demand flattening. how are you trading this news, pete najarian? >> i'm looking for a reason to start jumping back into some of these names, because i, frankly, agree with bob pisani and byron wheaton from the standpoint of this isn't anything new. we knew this was going to start flattening. ten years of 24% growth, it's just not something you expect to sustain. so, when you look at what's going on in the chinese markets, particularly the materials space here, the effects right now, i'm looking for an opportunity and i'm waiting to see some of those huge institutional buyers step in to names like caterpillar, names like joy global, maybe even some of the materials names themselves. we haven't really seen that yet, but that's the opportunity i'm looking for right now. i'm sort of positioning. we'll get into it later, but the banks i really like. >> josh, is this a time to get in or a warning sign to get out? >> we've been studiously avoiding anything with a high china bend, iron ore, coal -- >> why? >> w

smallcontinues today. cities in the offices of mitsui, people handle the processing and export of irone, coal, metals, chemicals, food, naturagas and wood chips. and they do it all without setting foot outside of australia's largest city, sydney. inll, three-quarters of the pution live in cities, making australia o ofthe ms in the world. kevin o'connor has eloredftthe s of theewarge cities that lie on the edge of the connent. in effect, from the earestimes the cities were controlling the country, but the cities themselves depended upon the export markets d coact with thstf world. sohe cies on the australian coast were the gatewayities. ey providee connection and they provided linkagesst between those markets and the restf rural australia. narrator: australia's european settlement began with the wool industry. within 5years, sheep grazers had opened up huge tracts of land in search of new pastures. the new land was well suited to wool production, and wool was also an ideal export; it was able to wittand the long journey back to britain's woolen mills. the low cost of oduction and the hi

or a china that consumes half of the world's iron ore and half the world man huge chunks of oil in copper so if you're investing in any of those things you have to pay attention to what's going on in china and so short term i'd be a little worried because i think china is going to do it it's slow down now but longer term if you can stomach the volatility i think it should be pretty well because. as as countries move to more of the industrial there is a move more into city tennessee commodity consumption rises to meet their long. ok and i want to know how government intervention that kind of all of these things both in developed and developing economies you see western central banks printing even just a story out today showed that maybe the fed has been monetizing some of europe's debt has some european sovereign debt on its balance sheet and on the flip side you have brics countries that are getting together talking about lending in their own currencies trading in their brain and be making their own development banks how does that factor into these investments yeah i think that's importan

here it is under construction and at last it was ready made out of iron pipe. more than 20 stories tall. powered by carbon arch lamps which were state of the art at a time. popular lamps that would later be popular at movie premiers. >> what they were doing is throwing a spark between two electrodes. it simply wasn't enough power to heat up -- to light up a significant area of downtown. >>> owen refused to admit defeat. he published stories of success including a testimonial from a survivor who claimed he could read his newspaper from 2 miles away. >> people said that chickens could not sleep two miles away because of this highlight power light over the city. >> reporter: even though it didn't light up the town, word of san jose's tower traveled to paris, the city of lights. >> there's a report that people from paris came here before they built the eiffel tower. >> reporter: public opinion was split. >> any project of that size would be controversial, there's no doubt about it. >> reporter: what little light people had in their homes came from costly gas lamps

and our last one is pay attention to your iron level. >> yes. >> how do you know? >> that's a tricky one. first, iron deficiency can cause anemia and that can cause you to feel very tired. we need 18 milligrams a day of iron and we lose it, in particular, when you menstruate. so if you're feeling tired and you're a woman in your menstruating age ask your doctor to get your iron levels checked. >> good ideas. feel better already. thank you so much. >> thank you. >> have a good weekend. coming up next you don't have to pitch a tent to sleep under the stars. we're going to show you luxury get aways to get back to nature. and the must-have spring staples all under 50 bucks. eat good fats. avoid bad. don't go over 2000... 1200 calories a day. carbs are bad. carbs are good. the story keeps changing. so i'm not listening... to anyone but myself. i know better nutrition when i see it: great grains. great grains cereal starts whole and stays whole. see the seam? more processed flakes look nothing like natural grains. you can't argue with nutrition you can see. great grains.

is that kind of ironic? >> yeah. very. we had been chatting like that on the way back, felt very lucky up to that moment. very ironic. >> rob, thank you very much. we're glad you're okay. we think maybe your video should be shown to people who think they're having a bad day. >> feel free. >>> a man fleeing from police crashed his suv. what you will see on dash cam video is how good samaritans help the police rescue this man this comes from my fox dfw. the incident started when the police tried to pull the driver over, and what they say was a traffic offense. they say the driver took off but the police did not give chase but the man crashed in this black suv. the officer himself first starts trying to get this call off this suspect. you see the people coming inside? they push the car up. watch what the officer does. he drags the man from underneath the car. now the suspect's legs were crushed. he was taken to the hospital and he later died. >> was anybody else injured in this accident? >> there was a passenger in the car. t
