the global $3000.00 talks would seem british researchers to take a more optimistic view. the world is not always a good point but it's much much clearer than it was. really getting better. a global $3000.00 special report. starts august 19th on the to. welcome to tomorrow to day the science show on t w coming up. next on live from home but was born 250 years ago we follow in the footsteps of the great scientist and explorer. the tablo physique is one of what's most important creations it

contains inconsistency as scientists have found out. and we head to florida where home but studied mining technology now researchers there are working on new ways of extracting metals. what. he wanted to see the world in its entirety at a time in european saw themselves as a period to other peoples and cultures alexander from home but sort of personal contact with his famous expedition to the americas reveal to him how everything was connected. multifaceted scientist explorer humanist humboldt is considered one of the last minister. alexander who was born in berlin at 769 growing up in a palace outside the city he was fascinated by rocks plants and insects from an early age after attending university. and working as
6:32 am
a government mine inspector he set off for the americas in 171009 it was a dream come true for a naturalist for 4 months we slept in the forests surrounded by crocodiles boas and jackie was eating nothing more than rice ants manioc and on occasion monkeys he wrote of the hardships and excitement of his expedition he returned after 5 years with a wealth of measurement data and botanical and geological specimens. vulcanology zoology ethnology just 3 of the many research areas to which he made important contributions. was celebrated in his lifetime he died in 859 in berlin his legacy is preserved in his great multi-volume work cosmos a comprehensive treaties on science and nature. how relevant is humbug today. to find out our reporter christiana coleman headed
6:33 am
out with a team to follow the route of her mother's expedition in south america. the trip took them to ecuador and colombia. in part one they climbed chimborazo an active volcano that is as much a challenge today as it was in how much time. 4000 readers above sea level on the north face of chimborazo the legendary volcano that and you know to prove don't enter mountable challenge for alexander. garcia wants to take us to the summit. our team is struggling with the thin air at
6:34 am
this altitude and we still have hours of ascent to head of us we're following the route taken 2 centuries ago by the famous explorer and naturalist. i really question about timing and i'm really passionate about being in one thing so of course 200 years ago if someone has arrived here and discovered this area and the like of course you fall in love with the lead in one thing. they can see how he was thinking how he can get to the top if you imagine he didn't know how high eighty's and just feel enough to go up and fight the measure the mountain and try to be enough play the floor.
6:35 am
as we call in the footsteps of onyx on one home board our expedition will take us halfway across south america. our journey begins here in ecuador and one of the world's highest capital cities. quito was the window on the heavens he and his companions set up a base in the spanish colonial town their objective to explore the region and document everything they encountered along the way. the basement of ecuador's national archives houses the priceless findings of their research trip. the maps correspondence and drawings produced by on board and stored here amount to over 4000 pages. historian and home board
6:36 am
expert is it going to him or do you know youngness has examined all the documents. in that moment the important thing is it possible to get one enormously important item is the passport issued to him but later that by the spanish government on may 7th mean 799. is important but again the name was for him to quote continue studying them i see and may collect sions observations and discover it was useful for the advancement of the natural sciences but it is so the less he said that without. the passport gave him board license to roam as he pleased through spain's colonial territories an extraordinary privilege for the time and one that he made maximum use of. in the space of 5 years he traveled from ben is away like to cuba colombia ecuador and peru then on to mexico exploring collecting and
6:37 am
measuring everything he came across on boats holistic approach to research combined precise data gathering with personal observations made during his journey he bridged the boundaries of scientific disciplines humble came to the americas to understand how all the forces of nature are intertwined and interconnected he was accompanied on his mission by his friend the botanist i'm a bump wrong the 2 men were on by jim but also the an active volcano which at the time was considered the world's highest mountain. resolved to reach its summit and . i've been out of mine up with him go up the mountain that's not something people do here normally at most maybe bring up luggage for visitors but no one goes up the mountain of their own accord was.
6:38 am
asked to see if he would ask. north where chimborazo can't be climbed by anyone who is bad or has failed again going across our. incredible north of where it will be it can only be inclined to fight people who are healthy when commuter who are well fed and who are on good terms with the lord he will say yes if you've done something bad in your life you won't make it work if you try you end up in line to your own crazy good or dead. that's. still determined to climb the colossus towering 6300 meters above sea level it was long considered. climbers from across the world. first internationally licensed female. c. i
6:39 am
remember one. and less. and i. think you'll. just need to trust yourself. my heart to be. climbing and because of that. i can inspire people to do the same. i never thought and when i became the 1st. and be like that but now is part of me. a respect for scientific curiosity grows where you approach the glacier it's our
6:40 am
1st time with this kind of altitude. as we continue our ascent so we can also see distinct changes in the vegetation. where. they stand now you can see. but they're disappearing as soon as we go high up the glacier is near so just some plants can survive you know many few meters from down below 0 to 300 meters is a big change. is going to disappear in the next 100 meters and so is the sergt. in these area b. cannot survive these on and off oxygen for them to be alive here. the trek from quito option but also was humble crowed like a botanical journey from the equator to the poles down in the valleys he saw
6:41 am
tropical plants and further up the mountain vegetation similar to that in northern europe as the explorer looked down on the mountain ranges below him he perceived the world with different eyes. later on board painting the now famous cross-section of chimborazo illustrating the different vegetation and climate zones it demonstrated the relationship between plant life and altitude and climate and patterns repeated across the planet the chimborazo map was a striking illustration of the complex interconnectedness of the natural world. it was forced to abandon his expedition a few 100 meters short of the summit of chin but also his way blocked by an impassable ravine. but he had climbed higher than anyone before him and his world fame was guaranteed. let's take a closer look at homeless children and that also known as the tabloid physique the
6:42 am
diagram contains data of great interest to modern day reset his own climate and ecology. but now a team of scientists has found some discrepancies in the data we talked on skype with french research it. was currently on an expedition in ecuador and i asked him why he's so interested in the tablet physique. working with colleagues. on. climate change on high altitude organisms. we soon realized it was. good of research. shoe gets as old information as we care so historical old information we can call bear with the current was issued of the organisms and of course in tropical regions we have both furious to record rickles and who is one of the
6:43 am
most important potential sources of information for that's going off historical records. that together with his colleagues he found that some of the pundits information about the altitude at which set some plans for granting was inconsistent. plus other editing notice which we also realize that is that most of his observation about her did use but occasion did not come from the chiller soap but from another monday in god and dishonor he was completely aware of that of course so the devil is it is not a saint if you look emotions perfect they can be used more they are just for new results it's a very important. document for the history of science. this is
6:44 am
a small cave where her daughter kenton 18 now to model a steam rediscovered it on one of their trips on humble it's expedition still a source of inspiration yeah of course it's very inspiring i don't have a description or how he climbed on the. he gets almost missed or snowblind he didn't have a. good good protection as it's a dirty drug to say once you are so where he suffered a storm and the reason why he could not observe the education hated you but it. is because there he was he suffered a storm just during his time so of course and not to say about. clothes where. his clothes was not adapted to to carrying a monkey so of course it's very pressing what's trained to do so such
6:45 am
a long explanation it's not a one in a. sense to him out there it's. explanations oh of course it's a mode. for more fascinating research results and expeditions go turned websites are fun i'll ask on twitter and facebook and to check out our special birthday web page full of stories related to alexander from home bites. numerous species of plants and animals have been named after oleksandr from home but they range from penguins. to screw monkeys. and that and speaking of that if you encounter incenting a question about a special thing they do. ringback why do bats sleep upside down.
6:46 am
in fact they spend most of their time hanging with their heads pointing down even for months at a time when they hibernate. nobody really knows how they evolve to do it. but that they do it has to think to them sieges as research has demonstrated. hanging from rafters or branches means they don't have to compete with other species for a place to sleep far from the ground they're less vulnerable to predators. and if they do sense danger they can make a quick getaway. drop flap and off they go in fact most bats can take off directly from the ground. but is it healthy to hang your head for hours or months on end uncomfortable well bats don't seem to mind their blood can pump from
6:47 am
feet to head and back to the heart without any problem. their body weight closes their claws by mechanical action it has to do with the way their tendons are attached. that means they don't expend any energy in order to roost upside down and if they die in that position they'll just stay put. but their hind legs and feet are not well suited to walking let alone running. spots also hanging downwards when they sleep the differences they took their head up against their chest. and as far as humans are concerned there's no evidence we can sleep upside down. bats are the only creatures known to science to hang their heads so much.
6:48 am
if outlet is read why are. you able to do you have a science question that you've always wanted answered we're happy to help out a little as a video text ovoid smell if we answer it on the show we'll send you a little surprise as a thank you god just ask. we like to ask you questions too and for this humble program we wanted to know what you associate with aleksandr from home but. we got a lot of answers from latin america where hobart continues to be popular. elizabeth estrada notes that hobart is very famous for discovering the ocean currents that bears his name. diego mulder not a points out that he was a great student of geography biodiversity and the anthropology of ecuador and he
6:49 am
quotes somebody as saying ecuadorians are strange and unique beings they sleep calmly amid smoking volcanoes live in poverty and incomparable riches and rejoice in sad music. mary blankets writes that she is so see him with education and the books with his impressions of mexico and she says he was a great historian. no better pin need a muscly know from mexico says humboldt represents the kind of german who loves the world science and truth and is an outstanding source for the understanding of mexico. better often visits an answer castle the volcano also known as nevada toluca. standing on the brim he thinks about how this one man could explore so many areas in such a profound manner thought was the perfect scholar a citizen of the world who sought the ultimate frontin. and beyond and he concludes
6:50 am
the true name of america ought to be on both land thanks for rising in. many modern technologies require special metals these resources are not always easy to come by but without them we'd have no wind turbines and no batteries. in fire back in eastern germany scientists are searching for new ways of extracting minerals and 1st they're not going under the ground but high above it. these men are treasure hunters searching for valuable minerals. they are following in the footsteps of alex hunter from white. their homemade drones designed to fly with sophisticated equipment upwards of
6:51 am
100000 euros. the aerial vehicle scans large areas with a device it's like this magneto meter. it measures variations in the big medic field of the earth which helps to pinpoint mineral deposits without elaborate and costly drugs the ones who do anything the you know we want to encroach as little as possible on people surroundings and environment because we want to gain acceptance on the population. the sun and the other aspects or efficiency and safety of your hard. drive ins unable to us together data rapidly without having to go there ourselves in. the data taken by the individual instruments are combined to give geologists an idea of the structure of the subsoil . * then they can guess where and which minerals they may find.
6:52 am
this method would have frayed alexandre for whom boyd in his day it was almost impossible to find deposits hidden deep underground. dominoes. no one back then mines were only in places where orders had been found on the surface when people found them they pursued them so excited today that's not possible anymore because practically the entire surface of the earth has been studied and we have to go down deep. there are currently around 5000 known minerals and many of them are under splay here in freiburg over the centuries they've been brought to the surface by miners and by researchers like. vaults that eat at the new we found at mining academy in freiburg. it was the 1st university of its kind in the bird and here home learnt the state of the art mining
6:53 am
technology of his time. yes at the buddhists this humble this one of the mining academies most famous students he looked for minerals not just here in freiburg but all over the world and bed. that is now the minerals have to be separated from the surrounding rock. in freiburg who voted learned the techniques for doing it the much touted so how to crush the rock for example by using stem cells to break down the rock from the or mountains all we needed were methods for separating the larger pieces. that made it possible to extract silver iron and. but minister it's like germanium indium and duryea earth are a different story today we need them for when turbines electric car batteries and
6:54 am
so. funds these elements are generally either not very abundant are not concentrated in deposits martin who drove studies how to recover these minerals from crushed rock. using water and a number of chemicals the frothy by after is prepared for the minerals. ideally the desired mineral particles were to guess bubbles and dry ice to the surface. there they can be skimmed off layer by layer. the problem is this so-called flotation technique is not environmentally friendly in part because of the flotation reagents. one strategy and making the production more eco friendly focuses on the chemicals we have to research projects that are trying to replace the chemicals by a biological reagents that is we use microorganisms send their diverse interaction
6:55 am
with the materials to get tailor made reagents from these microorganisms in the quarters ones who are designed not to these are produced naturally and are more ecologically compatible and now can help reduce the need for harmful some fetter creations. we both would also like to reduce the amount of water at least for the trusses you would force them and of course in my research the dream would be to no longer use flotation but to find a separation process that works in the dry state so we don't have the water problem but that's something we're working on. making flirtation more environmentally friendly would have another important impact it could then be used to recycle products to recover the valuable minerals. present day treasure hunting has very much in whole spirit the big picture in mind.

our journey in the footsteps of alexander from home but continues next week when our reporter visits the avenue of the volcano in ecuador. join us for more of his impressions inspired by her most expedition until then good bye.
