The weather heavy rain all spread southeast across much of the country tonight windy again later on today with rain playing to sunshine and blustery chalets frequent in the north on the west it's not a. Fresh poll since. The F.A. Cup quarter final stops us and I would like commentry food be Crystal Palace and since it's the M 5 followed by swarms he says he does this mean just to stay safe from $555.00 lifeforce extra cost extra dough to call as good morning to. Dr Dot new sound as though there is a slot imbalance in the force in your throat different bacteria and I have a come previously inhabiting bacteria that's right kind of you to say but it's not about my condition it's about the questions our listeners have about the natural world and natural phenomena the dumbest accord if you'd like to join in on this phone and daughter calls for an end it is 8 o 8590969308085909693 and talking of all the conditions I have don't to call me Dr Lisa Our own Lisa McCormick I visit I'm going to be the Michael Gove here to reason my that's very terrible analogy I know but it seemed appropriate. To spread program I'm of the way you did that as well sides. Gender specific Oh yes specific Yes I mean on specific I think any Good morning doctor called Good morning doctor I don't think I have ever talked with you and said so the number to call is 080-859-0969 through all the docs Elisa could do that but the main Well you know if you were to call if you got a questions a way to wait 590-9693 You can also text is 850580 if you want to e-mail that is up all night B.B.C. Co dot U.K. It just needs a little bit of extra help I think. To call I think don't to Dalton you can you can just sit back a little way they saw our comfortable and get some milk and honey if this or that sounds like a really really good plan actually I found out how the honey works with a sore throat Oh that's interesting yeah the standard explanation that honey lands on the vocal cords and does stuff to them as always bothered me because on the other saw the vocal cords you got the lungs and once in there's no way out you check in you don't check out and that always seemed wrong in fact getting food in the lungs is considered very bad and then one day when already a stations somebody ring in who was and a neat that is to all the Americans call it and the theologist or as we strains would call it a gas person. Conscious and he said that he had written a paper years earlier don't know why and he thought this is really about this except they do shove lots of stuff past the airways that what the honey does is it very quickly in your mouth it changes the bacterial make up into something else you know so you've got lots of bacteria in your mouth is all different ones they're all good they're all friendly they all love you to pieces but you change that bacterial make up and so the bacteria that exist in the So a lot of that is up lubricate your vocal cords changes and it's that that makes a difference but then I asked him to simian the original paper and he didn't and I look for it in google scholar and I couldn't so if anybody can follow me the paper play said to me a duck a doctor called D O C. K R O on Twitter just talk to Col the long version and I'd love to be able to give some scientifically proven advice to put up and he's right very kind of I'm going to go if you don't mind don't release I'm going to go off lately I'm looking for B. a B. You know where the actual baby will be good luck with that. I'll be back very sure you don't want or I might be really concerned afraid just let me know you some honey had a friend somewhere oh it's all right OK It literally has Dr Cawley's let me have this to it so she could go on that crack on both you know and he said he might be a little while Yeah when I was in the Antarctic a few weeks ago I said to my family there's a blizzard out Saud I'm going to go out comma or I may be a little while reflecting the words of it's in the DO and Scott's Antarctic expedition to the south pole like I came back it's like it's like don't think I'll never be going to get to the point of the night where some of some of our listeners have incredibly clever questions to ask you and sometimes I read them and I think I'm not sure if what I'm saying is making sense so before we do that can we talk about rubber billons Yes this is been a problem of going back over the last several weeks where one of the listeners rang in and said How come when I break a blues always breaks into 3 pieces Yeah and I didn't have a good answer and then some of the listeners started sending me and says Thank you Mr Newton and other people started coming on my Twitter feed and then sit me to the original Piper. Is actually in the original paper called wait for it popping balloons a case study of dynamical fragmentation and you're thinking why on earth would anybody certainly people with the names of Sebastian Miller in A and mocked. That he are. Friends Why on earth would they want to know about this kind of stuff because fragmentation which is what the balloon is doing happens all around us in the world we live in now what happens in fragmentation is for example a big asteroid Mark laws and break up into smaller ones or big chemical might break into smaller chemicals or you might have. In a little jar and you person squeeze the thing and it fragments into smaller droplets of water or in a war fragments or fragmentation is actually a very big part of material science says a whole universe in a degree material size so they did this popping balloons a case study in dynamical fragmentation and he comes he ends up falling 22 before I was to read it. When you blow up a balloon you push into the balloon of course the air is under pressure Shaw and the rubber membrane from which the balloon is made gets stretched. Yes And is some stress in it now suppose that you top of the balloon to not when it's only half inflated and then it actually brushed up against some shop tinsel or something in the Pops Well there's only a love to amount of energy in the rubber membrane and so at the point where the shop thing hits the tinsel there's a hole and then that forms a crack which spreads in 2 directions and it breaks the balloon into 2 separate fragments but. If you really pump up a balloon hard if you push it really really hard and shove a lot of air into it and follow it pops when it's fully inflated or the because you over inflated it or because when it was inflated You hit with the pin which is when when is a lot of stress in that rubber well that rubber has that stress has to be relieved quickly and it can't be relieved quickly by just one crack because the crack will only move at a certain speed so what happens is that one crack the little hole that you start off with turns into $2.04 and suddenly you've got a whole myriad of cracks all parallel to each other it turns out they do some we shape the stuff and so you need a whole bunch of cracks all moving at the same speed to dissipate the energy and water on so you probably learn which is in fried to a medium pressure you get one crack 2 halves at high pressure you get a bunch of fragments and says Thank You to all the listeners who gave me the answer on Twitter and pointed me in the direction of this paper from October 2015 Thank you you I love you to pieces to the people I like it that's a good that's a good 1st question that's a good 1st topic to address I like it can we just bring it down hill from there. Well it's just because I go to read Anthony's message I've got to say I mean you probably don't have it on you want to bounce it for you kind of an answer for it but we have to read it anyway so it's a call can you tell us hi to manage Breck's it in a mean a meaningful way because those Brits have lost the plot. Ah all would invoke a quantum universe where everything possible that can possibly happen will have happened and then pick the best pathway in retrospect now Jimmy. Cliff physicist and with whom I have danced on stage at one of the Broadway in Cox Christmas hemis Ms Odeon things I was part of the stogie Odense a thing he's written a book called quantum life and in his he says that quantum effects you know all that we'd quantum stuff he says is absolutely essential not just down in the subatomic level but for living creatures so certain birds navigate with magnetic fields using quantum effects. In the air when you are listening to the quietest sound you can possibly hear the drum itself moves back and forth a distance equal to the diameter of a hydrogen atom something quantum going on there and in plants there's a whole bunch of PAS ways by which they can extract the energy from the sun lot and somehow the energy goes down all of those pathways at the same time and then the plant picks the most efficient one so in the same way make the Universe A Quantum universe and just by thinking about it change it to the reality that you want. But you have all the answers. To work because train are still coming their planes will be in the air without permission to land in Europe but in that case you won't even think about them I think we should probably move on to more about the not real well they're not sure phenomena that our listeners have been pondering this week results only in London texters don't recall he says last week you said at the beginning of the show that you couldn't remember which of the tropics was which So he wants to give you a little bit of a bit of a help on this right there he says imagine in your mind's eye the words cancer and Capricorn written vertically rather than horizontally right. And draw a line through the middle of each representing the equator night if the letter and appears in both equals north then the and in cancer appears above the line or north of the equator and the and in Capricorn appears scythe of the equator So cancer is the northern drop. Karen says CIA in 3rd with her see so in a piece above the quite idea. Let's have a lot isn't you monic. That the place is so wonderful and it's easy to remember which I like Yes I have a terrible memory so any such I really deeply beloved thank you so much that seems like a nice one but let's crack on then what people are asking this week but I'm just going to strew trying to scroll through here OK right we have got from Ken in Orkney morning to you can Ken says don't you call with mines continue desire to build even bigger structures and huge cities and given the weight of the structures yet the world still spins as per normal so can't question is Why doesn't the weight affect the world spinning on its axes given the arbitrary way in which bills these colossal buildings. Well actually has. Yeah get ready for it OK So firstly think of a spinning bicycle will which is running perfectly true you've got in little actual mountain you spinny of it really high speed and then stop it and then put a little lead white somewhere just anywhere after one saw it and the will will start wobbling differently because you just shifted what was previously stable balance say you cool with it that you can shift the balance of something by shifting some weight from here to there. I the 1st thing 2nd thing we humans have shifted or shift each year about 30 belief a 1000000000 tons of stuff call iron ore and the like from here to there and that has not been enough to shift the Earth's spin axis and by coincidence as roughly equal to what all of the rivers of the world shift each year 30000000000 tons. Point number 3 but by shifting 600000000000 tons of stuff we have tipped the earth off its axis. So the Earth is spinning on a North-South axis and that spin axis is gradually or was was gradually moving very slowly towards the direction of the quite or at $6.00 to $7.00 centimeters a year but in 2005. It's switched to firstly throwing out chucking a lefty that is is that a strike in term known in the Mother Country chucking Alicia de la I've never heard of it but don't adult has written these go spit in His hands of a 70 some have you heard about I've never heard of it tickled me by the way this one is ticking me as well did you steal it from the fridge but instead I went aboard. And it's still this is. I'm OK financially. So with $100.00 New Englanders running around your mouth and little mix with the saw that because the saw a lot of us there were changes bacterial make up and then the saliva dripping upon your vocal cords will hopefully make them better so was a god to the spin axis yeah but it has and I thought is interested in you so the spin axis of the earth the north south spin axis instead of. Slowly migrating in the direction of the a quite at 6 centimeters a year. Turned left and started running parallel the a a quite a and then secondly accelerated to $26.00 centimeters a year and this is what you would expect if you do the mathematics of melting $600000000000.00 tons of water ice near the pole and allowing centrifugal effect to throw towards you quite out. So the Earth spinning has thrown the oceans up by heart of about 8 kilometers the earth would stop spinning magically then gradually the oceans would recede some 8 kilometers so if you do the mathematics of melting far global warming $600000000000.00 tons of ice every year which is what we're doing and then let that water bus interview all effects flow towards you quite or that would cause the measured change that we have found in the spin axis of the earth so he's building big building buildings that's only a 1000000 tons couple 1000000 tons that's not enough even when we shift directly 30000000000 tonnes a year is not enough you need to shift 6 $100000000000.00 tons a year and now we humans can proudly stand back and look at our work and say look we did it we managed to shift the years of attacks is a tiny tiny amount it's not going to have any effects but we have bench to do it in trust in the interest of Ken I'm sure that answered your question. Shall we bring in Dr David Carr down Dr David out to David unhitching Good morning. Thank you heartily thank you very very much and you've joined us this morning. OK I'm always going on about climate change and suchlike and you know we are interested in plastic and we were talking about a year ago next but I'm thinking that there are 4140 minutes a day now that means if you have a breast intake and expects 0 except. Once every 10 seconds that's 14400 cycles or you're taken in any one dyke. Has anybody done a treatise on how much oxygen and person uses just in a normal walking alone exertion and how many trees that would require for one person to bring one day or one week one year. Ah. Be easy enough for anybody to work out I can't do it quickly enough to be able to give you an answer in a reasonable time otherwise we'd have lots of did time on it but show you just multiply the numbers and then compare it to what else is going on in the world. He did this with each breath you put out I think I think it's 40 milligrams of carbon dioxide per breath I think from memory OK But yes you are right we do consume oxygen we do put out come dockside and there is a balance we have evolved along with the plants that many fractures the oxygen intake in the carbon dioxide these plants exist roughly roughly half on land and half in the ocean with cold plank torn both of them from the Greek root meaning wandering Oh yeah yeah yeah so I don't have the answer for you Dr David as to what percentage of carbon dioxide output we humans have as compared to industry guessing it would be Marcus' copy of the order of say 1000th of a percent of the total human output of carbon dioxide. OK. Cars here. On the planet I just wondered how much we were using up on what we were talking about us by numbers but. What you said has made me believe that. This is Speaking of isolation going to do you can look it up and if somebody can do the
