Complain that School Children learn to solve problems but rarely ever acquire a grasp of underlying mathematical principles what do you think are they right we asked on twitter. How do you remember your math classes forty one percent of you love them more than expected. Thirty seven percent said they could take it or leave it. Well around one in five of you hated math class with a vengeance. Adding music to the mix might have changed a few minds this project shows how. Much money i know much of. The student your hundred boyish has written some math songs that have become internet hits. Even help in understanding the pythagorean theorem. To. The. Big. Book. Music is magical for learning math music teacher marcus love a check wants to take the you tube concept and bring it into the classroom he calls it the musical way to learn math. Women mostly commit if you bring music into the lessons of other subjects it works magically the subjects automatically grow more interesting explaining becomes easier the child gets the opportunity to actually do something ok its home. Math and music are siblings rhythm chords and harmonics all work according to mathematical principles if the math behind the music is correct then we perceive that music as beautiful. Thats also true for a complex music pieces like this japanese song it has special rhythms that work well as an experiment during math lessons whoa whoa whoa whoa cause. When its all right lets try it all together ready oh oh oh oh oh oh god oh cause i. Know me well singing the students and this was classroom im supposed to visualize what they hear that means they should interpret and write down on paper the laws and rules of the tones in beats they hear they dont write musical notes they use pictures and symbols experts call with the students are doing mathematics zeeshan what the next year has mathematics zation means translating and everyday situation into a generally abstract language upstroke extracting an actual situation and trying to recognize the laws behind it. Its masticate its a kind and these are the colors represents a pause and the x. s represent the notes and. You can assume overlays that you had to grade the top is like a key and thats also a. Rick you can use. You can invent some characters and then say blue is pink is high this red is a pause. Green is even higher. In this exercise the goal is to find a new way to think about math by using music but congress is divided into two groups half of the class is clapping their hands in a circle counting from one to thirty all multiples of three are substituted with the word pain then they move to multiples of four. Up the other half of the class is at the blackboard they listen to the group in the circle and try to recognize the pattern. That. Is immediately the pattern has to have a certain amount of regularity but if you follow the game and your multiples of three exercise its easier because you always see the same person but with a multiples of four there are always different. I thought the experiment was good. Its good that you can combine maxim you sick on the one hand you have to collapse the rhythm properly and on the other you have to think about the multiples. Perhaps there will soon be a subject called math and you sick until then students can learn arithmetic with the help of songs written by johann boyish. The some of. The. Music can sound like this. Or like this what different styles have in common is an ability to touch us and the power to heal. This. Is something that if it does is it. Done at this cafe in zero eight people dance their warnings away its refreshing and good exercise. Because it is the most suffer from dementia even if its not always obvious to outsiders. A little dish to let it be music gets both body and soul moving it happens automatically. Believe in seventy five has alzheimers it was diagnosed two years ago. He comes here regularly with his partner. At the egyptians will have noticed that there is more within me than i knew about any of you know ive been learning a new language thats called movement to be wreckage the fluid could be made but i dont have to dredge my memory the same just happens on the spur of the moment this is. A. Dementia pretty much shuts down the brain neurons die and are not replaced. Thomas pickel is sixty six and his dementia is advanced he can no longer speak most tasks are beyond him. But when he hears the music here he starts to dance with his wife christina. Was going to academia as he never used to dance it started with his dimension anything that reaches the Soul Movement it becomes more important as the mind ceases to do what it used to now its more about feelings made this group go on. Seventy three he had a. Stroke a few weeks ago and can hardly speak now rehab involves music it should help him learn to talk again. The stroke often damages the Language Center in the brain music can help reactivated music stimulates many regions of the brain. For example the order to record checks. For learning and Memory Center and the regions associated with remembering sounds and melodies music triggers emotions that happens here. Singing or playing an instrument activates this region. Listening to or making music stimulates the restoration of language by creating or enhancing connections between a whole range of systems in the brain. Bruno said a solo comes in right on cue. To name a verb gave. Him. When. Thats cute guys thats the means for him if were lucky and impatient used to sing a last song stored in their memory then theyre all for people to call up the words of the lyrics in connection with the melody or does this need to he it wants an island emotional terms thats a very big deal when they realize they can still do that and they can sing and the words just come to them at the right moment thats a possible. Mind. You know. Son. Or a soul is a good example hes had a hard time talking but he can sing very well its not the Language Center thats activated but other regions of the brain. You know he. Was. The feral he was not bad zinc she told him the way he won the singing lessons this. Was are somehow liberating. But for i in this prayer for i in this potential cause a fox who picked him up on fung says patient has made excellent progress and first he couldnt are sure of words on some hour you could tell he knew what he wanted to say but he couldnt find the words to say as one gets nuff feel walking. Your ways later he can form sentences written to say what he wants as its vital you go and. When i was not some kind of automatic response he cant really express himself. If. I had the cafe the party is in full swing. I see your shit in six weeks but the leader in law is eighty four and her dementia is far advanced still has one song that always does the trick suddenly shes wide awake and on her toes she didnt see anything. I think it would say that its resonates somewhere deep inside field songs from long ago are still familiar i find it so touching to see her the way she used to be much help me a good time. Baby if it was ever if it was. Everyone is in a good mood and somehow liberated if for a moment thanks to the power of music. These sponges are surrounded by water music and speaking of sponges what are they and biological terms anyway many people might guess their plants but theyre not theyre animals when it comes to the science of life sometimes the i deceives and thats not just true of sponges. From what wants to know. Whats the difference between fruit and vegetables. The botanical answer vegetables are plants with leaves and roots. But the fruit always grows from blossoms except that zucchini blossoms dont produce any for it or do that it can be confusing biology is usually viewed as an orderly scientists. For example are vertebrates that live in water and have gills. Birds are vertebrates that have feathers. And mammals are vertebrates covered in hair. But try to differentiate between a fruit and vegetables and even scientists can get a little confused it doesnt help to judge the matter based on sugar content either take care as for example they can be really sweet but theyre still considered a vegetable the bottom line is that society decides what it considers to be a fruit or a vegetable. Real fatness used another criteria. They call annual plants that have to be sown a new each year vegetables. Whereas fruit grows on perennial trees or shrugs putsch lived for many years and apple tree can live for a century or even longer. But even here there are exceptions like asparagus a perennial vegetable but no matter what you choose to call them in the end its the flavor that matters. If you have a science question to write us if we decide to showcase your query on the program well send you a d. V. D. Of our animated einstein explaining many of the great scientists theorise. The most important thing is to never stop asking questions. In Human Development some phases are more difficult than others puberty for example causes huge physical and emotional changes. Experts say this period is accompanied by changes in the brain. And during pregnancy a similar process occurs. Having a child is a high point in many womens lives a source of great joy and fulfillment the whole process brings physical and emotional changes. But in fact all you have it back at our after i go i was very happy full of love in every fiber of my being and everything was suffused with joy flashes of feeling. I was just saved and emotions. Say i am whats healthy and im good at it. But everything changed suddenly when my daughter was born in motion my thoughts it was brutal i wasnt the same person anymore i never used to be frightened but i am now im much more wary i never used to have second thoughts about things but i do now. So what exactly does change and what are the causes a psychologist a neuroscientist erica from Barcelona University spent eight years researching the issue she worked with a group of women who were planning to have their first child she took brain scans before they got pregnant and then after they gave birth and then again two years later. Barbara miller compared the scans to those of women who didnt have children her conclusion after a woman gives birth her brain is no longer the same. I dont know if that women became of the volume of grain much of it in a certain specific regions decreased moment this was done she had goodies and that was true for all the mothers in the test the regions that changed are marked in yellow. In the summer maybe half in this crosssection you see the changes at the front and back you are who are. There we see them from a different perspective its just that this. Shrinking gray matter is also been observed in children in the run up to puberty the phenomenon has been dubbed synoptic pruning head start to be an indicator of learning and specialisation the hypothesis is that in pregnant women a similar process of preparation takes place and hansing the mothers ability to recognise the needs of her child. In those islands xiang they look at we think it has to do with whats known as a mothers instinct. To see thats what helps the mother recognise whats going on and have a basis and enables her to tell if its hungry or in pain it is tired ok this was going to give it a corner. And you know the changes take place in regions associated with social cognition an area often called Emotional Intelligence the volume reduction showed a substantial overlap with brain regions involved in a womans response to her baby after its born scans were also made as women were shown photos of their own in other babies so miska sac dave in wonderland when a mother sees her own baby theres increased activity in exactly the regions that change during pregnancy. Where we see a shrinkage of the grains. Ideas that doesnt happen when she sees another baby. But i still thought i had a four. Its thought the flood of hormones that comes with pregnancy somehow causes the changes in the brain progesterone levels for example search ten to fifteen fold baba miller and her colleagues believe that the changes in. The brain prepare a woman for her role as mother. A lot of them in the family and they make a bit of well that is probably the case that these women can recognize faces but no doubt in order to protect themselves from risks or to improve their ability to find a hold of the. Czar interpretation. Is the most those things that us here on. The study shows that the changes endure for at least two years after a woman has given birth there are many Unanswered Questions such as when exactly during pregnancy the changes take place and what exactly triggers them. To have offspring almost all animals first have to find a partner. For human beings thats generally associated with falling in love a time of glowing feelings and emotional upheaval but the stars of our next report have their own way of going about looking for partners as they glow too but in a very different way. I warm summers night at the end of june in cologne. The whole city is illuminated. No one here has any idea what the fight to take place just a few kilometers ahead of time and a glorious spectacle i wonder of nature and. Its well worth a trip into the forest. Any cool visa and mohamed my mary has come to witness the magic that takes place here every season the night before muhammad sold a show for the first time this year the stars are bugs. Theres other here body there were huge swarms of them further in by to hide we could start here for several hours here last night as you set up camp here exactly. Arsenal one more time was it its our spirit of ten pm its going to take a while so i. Am. Then at a quarter past ten this show begins. The power of the firefly also known as lightning. Only the males are. Hundreds of dancing. Around. The show takes place for one reason only to find. Memory and of course i like to imagine that the light has been here for millions of years or more before humans showdown you know before they were electric light fascinates me theres something poetic about it its called utils. But what makes the fireflies glow and what do they look like up close. To the top. Half ass of. A slightly larger. Diamond. Klein a little brown bug nondescriptive in the light in a good duckling and. Quite understand is one stuck in a spiders web. It may be trapped but it keeps on glowing. The light producing organ its at the back of the abdomen. A Chemical Reaction in the cells create the lifes. Almost all of the energy gets turned into lice. Theres no artificial light thats more efficient but where the females just exist or looks very much like a female sort of. A lot of us reports are its almost buried in the dry leaves you can hardly see. The females just fish on the forest floor without moving they light up much later than the males. Scientists believe the females only send out light signals after theyre stimulated by the males beginning to glow then their light attracts the males. For male fireflies its crucial to quickly find a name mating its first come first served. After making the males love light fades away and they die. The females also shut off their lights and begin with egg production. Two days later theyll die as well. After ninety minutes the spectacular show is over. But for the next few evenings the fireflies will be out there searching for anything. An organisms ability to emit light has a name bioluminescence. It occurs when a protein called the lucifer in and an enzyme called the lucifer range react with energy rich a. T. P. Molecules and oxygen. As the report mentioned this chemical process is a very efficient. Ninety five percent of the energy it produces is emitted as light just five percent as heat. Within can doesnt light bulbs that ratio is reversed. In efficiency inspired researchers to make l. E. D. S. Modeled on firefly its.
