my subject today is learning. and in that spirit, i want to spring on you all a pop quiz. ready? when does learning begin? now as you ponder that question, maybe you're thinking about the first day of preschool or kindergarten, the first time that kids are in a classroom with a teacher. or maybe you've called to mind the toddler phase when children are learning how to walk and talk and use a fork. maybe you've encountered the zero-to-three movement, which asserts that the most important years for learning are the earliest ones. and so your answer to my question would be: learning begins at birth.
well today i want to present to you an idea that may be surprising and may even seem implausible, but which is supported by the latest evidence from psychology and biology. and that is that some of the most important learning we ever do happens before we're born, while we're still in the womb. now i'm a science reporter. i write books and magazine articles. and i'm also a mother. and those two roles came together for me in a book that i wrote called "origins." "origins" is a report from the front lines of an exciting new field called fetal origins. fetal origins is a scientific discipline that emerged just about two decades ago, and it's based on the theory that our health and well-being throughout our lives is crucially affected by the nine months we spend in the womb. now this theory was of more than just intellectual interest to me. i was myself pregnant while i was doing the research for the book. and one of the most fascinating insights i took from this work is that we're all learning about the world even before we enter it.
when we hold our babies for the first time, we might imagine that they're clean slates, unmarked by life, when in fact, they've already been shaped by us and by the particular world we live in. today i want to share with you some of the amazing things that scientists are discovering about what fetuses learn while they're still in their mothers' bellies.
first of all, they learn the sound of their mothers' voices. because sounds from the outside world have to travel through the mother's abdominal tissue and through the amniotic fluid that surrounds the fetus, the voices fetuses hear, starting around the fourth month of gestation, are muted and muffled. one researcher says that they probably sound a lot like the the voice of charlie brown's teacher in the old "peanuts" cartoon. but the pregnant woman's own voice reverberates through her body, reaching the fetus much more readily. and because the fetus is with her all the time, it hears her voice a lot. once the baby's born, it recognizes her voice and it prefers listening to her voice over anyone else's.
how can we know this? newborn babies can't do much, but one thing they're really good at is sucking. researchers take advantage of this fact by rigging up two rubber nipples, so that if a baby sucks on one, it hears a recording of its mother's voice on a pair of headphones, and if it sucks on the other nipple, it hears a recording of a female stranger's voice. babies quickly show their preference by choosing the first one. scientists also take advantage of the fact that babies will slow down their sucking when something interests them and resume their fast sucking when they get bored. this is how researchers discovered that, after women repeatedly read aloud a section of dr. seuss' "the cat in the hat" while they were pregnant, their newborn babies recognized that passage when they hear it outside the womb. my favorite experiment of this kind is the one that showed that the babies of women who watched a certain soap opera every day during pregnancy recognized the theme song of that show once they were born. so fetuses are even learning about the particular language that's spoken in the world that they'll be born into.
a study published last year found that from birth, from the moment of birth, babies cry in the accent of their mother's native language. french babies cry on a rising note while german babies end on a falling note, imitating the melodic contours of those languages. now why would this kind of fetal learning be useful? it may have evolved to aid the baby's survival. from the moment of birth, the baby responds most to the voice of the person who is most likely to care for it -- its mother. it even makes its cries sound like the mother's language, which may further endear the baby to the mother, and which may give the baby a head start in the critical task of learning how to understand and speak its native language.
but it's not just sounds that fetuses are learning about in utero. it's also tastes and smells. by seven months of gestation, the fetus' taste buds are fully developed, and its olfactory receptors, which allow it to smell, are functioning. the flavors of the food a pregnant woman eats find their way into the amniotic fluid, which is continuously swallowed by the fetus. babies seem to remember and prefer these tastes once they're out in the world. in one experiment, a group of pregnant women was asked to drink a lot of carrot juice during their third trimester of pregnancy, while another group of pregnant women drank only water. six months later, the women's infants were offered cereal mixed with carrot juice, and their facial expressions were observed while they ate it. the offspring of the carrot juice drinking women ate more carrot-flavored cereal, and from the looks of it, they seemed to enjoy it more.
a sort of french version of this experiment was carried out in dijon, france where researchers found that mothers who consumed food and drink flavored with licorice-flavored anise during pregnancy showed a preference for anise on their first day of life, and again, when they were tested later, on their fourth day of life. babies whose mothers did not eat anise during pregnancy showed a reaction that translated roughly as "yuck." what this means is that fetuses are effectively being taught by their mothers about what is safe and good to eat. fetuses are also being taught about the particular culture that they'll be joining through one of culture's most powerful expressions, which is food. they're being introduced to the characteristic flavors and spices of their culture's cuisine even before birth.
now it turns out that fetuses are learning even bigger lessons. but before i get to that, i want to address something that you may be wondering about. the notion of fetal learning may conjure up for you attempts to enrich the fetus -- like playing mozart through headphones placed on a pregnant belly. but actually, the nine-month-long process of molding and shaping that goes on in the womb is a lot more visceral and consequential than that. much of what a pregnant woman encounters in her daily life -- the air she breathes, the food and drink she consumes, the chemicals she's exposed to, even the emotions she feels -- are shared in some fashion with her fetus. they make up a mix of influences as individual and idiosyncratic as the woman herself. the fetus incorporates these offerings into its own body, makes them part of its flesh and blood. and often it does something more. it treats these maternal contributions as information, as what i like to call biological postcards from the world outside.
so what a fetus is learning about in utero is not mozart's "magic flute" but answers to questions much more critical to its survival. will it be born into a world of abundance or scarcity? will it be safe and protected, or will it face constant dangers and threats? will it live a long, fruitful life or a short, harried one? the pregnant woman's diet and stress level in particular provide important clues to prevailing conditions like a finger lifted to the wind. the resulting tuning and tweaking of a fetus' brain and other organs are part of what give us humans our enormous flexibility, our ability to thrive in a huge variety of environments, from the country to the city, from the tundra to the desert.
to conclude, i want to tell you two stories about how mothers teach their children about the world even before they're born. in the autumn of 1944, the darkest days of world war ii, german troops blockaded western holland, turning away all shipments of food. the opening of the nazi's siege was followed by one of the harshest winters in decades -- so cold the water in the canals froze solid. soon food became scarce, with many dutch surviving on just 500 calories a day -- a quarter of what they consumed before the war. as weeks of deprivation stretched into months, some resorted to eating tulip bulbs. by the beginning of may, the nation's carefully rationed food reserve was completely exhausted. the specter of mass starvation loomed. and then on may 5th, 1945, the siege came to a sudden end when holland was liberated by the allies.
the "hunger winter," as it came to be known, killed some 10,000 people and weakened thousands more. but there was another population that was affected -- the 40,000 fetuses in utero during the siege. some of the effects of malnutrition during pregnancy were immediately apparent in higher rates of stillbirths, birth defects, low birth weights and infant mortality. but others wouldn't be discovered for many years. decades after the "hunger winter," researchers documented that people whose mothers were pregnant during the siege have more obesity, more diabetes and more heart disease in later life than individuals who were gestated under normal conditions. these individuals' prenatal experience of starvation seems to have changed their bodies in myriad ways. they have higher blood pressure, poorer cholesterol profiles and reduced glucose tolerance -- a precursor of diabetes.
why would undernutrition in the womb result in disease later? one explanation is that fetuses are making the best of a bad situation. when food is scarce, they divert nutrients towards the really critical organ, the brain, and away from other organs like the heart and liver. this keeps the fetus alive in the short-term, but the bill comes due later on in life when those other organs, deprived early on, become more susceptible to disease.
but that may not be all that's going on. it seems that fetuses are taking cues from the intrauterine environment and tailoring their physiology accordingly. they're preparing themselves for the kind of world they will encounter on the other side of the womb. the fetus adjusts its metabolism and other physiological processes in anticipation of the environment that awaits it. and the basis of the fetus' prediction is what its mother eats. the meals a pregnant woman consumes constitute a kind of story, a fairy tale of abundance or a grim chronicle of deprivation. this story imparts information that the fetus uses to organize its body and its systems -- an adaptation to prevailing circumstances that facilitates its future survival. faced with severely limited resources, a smaller-sized child with reduced energy requirements will, in fact, have a better chance of living to adulthood.
the real trouble comes when pregnant women are, in a sense, unreliable narrators, when fetuses are led to expect a world of scarcity and are born instead into a world of plenty. this is what happened to the children of the dutch "hunger winter." and their higher rates of obesity, diabetes and heart disease are the result. bodies that were built to hang onto every calorie found themselves swimming in the superfluous calories of the post-war western diet. the world they had learned about while in utero was not the same as the world into which they were born.
here's another story. at 8:46 a.m. on september 11th, 2019, there were tens of thousands of people in the vicinity of the world trade center in new york -- commuters spilling off trains, waitresses setting tables for the morning rush, brokers already working the phones on wall street. 1,700 of these people were pregnant women. when the planes struck and the towers collapsed, many of these women experienced the same horrors inflicted on other survivors of the disaster -- the overwhelming chaos and confusion, the rolling clouds of potentially toxic dust and debris, the heart-pounding fear for their lives.
about a year after 9/11, researchers examined a group of women who were pregnant when they were exposed to the world trade center attack. in the babies of those women who developed post-traumatic stress syndrome, or ptsd, following their ordeal, researchers discovered a biological marker of susceptibility to ptsd -- an effect that was most pronounced in infants whose mothers experienced the catastrophe in their third trimester. in other words, the mothers with post-traumatic stress syndrome had passed on a vulnerability to the condition to their children while they were still in utero.
now consider this: post-traumatic stress syndrome appears to be a reaction to stress gone very wrong, causing its victims tremendous unnecessary suffering. but there's another way of thinking about ptsd. what looks like pathology to us may actually be a useful adaptation in some circumstances. in a particularly dangerous environment, the characteristic manifestations of ptsd -- a hyper-awareness of one's surroundings, a quick-trigger response to danger -- could save someone's life. the notion that the prenatal transmission of ptsd risk is adaptive is still speculative, but i find it rather poignant. it would mean that, even before birth, mothers are warning their children that it's a wild world out there, telling them, "be careful."
let me be clear. fetal origins research is not about blaming women for what happens during pregnancy. it's about discovering how best to promote the health and well-being of the next generation. that important effort must include a focus on what fetuses learn during the nine months they spend in the womb. learning is one of life's most essential activities, and it begins much earlier than we ever imagined.
thank you.

why does this matter? boy, it matters a lot. because no one gets to the corner office by sitting on the side, not at the table, and no one gets the promotion if they dont think they deserve their success, or they dont even understand their own success.i wish the answer were easy. i wish i could go tell all the young women i work for, these fabulous women,"believe in yourself and negotiate for yourself. own your own success." i wish i could tell that to my daughter. but its not that simple. because what the data shows, above all else, is one thing, which is that success and likeability are positively correlated for men and negatively correlated for women. and everyones nodding, because we all know this to be true.theres a really good study that shows this really well. theres a famous harvard business school studyon a woman named heidi roizen. and shes an operator in a company in silicon valley, and she uses her contacts to become a very successful venture capitalist.

when i was about three or four years old, i remember my mum reading a story to me and my two big brothers, and i remember putting up my hands to feel the page of the book, to feel the picture they were discussing.
and my mum said, "darling, remember that you can't see and you can't feel the picture and you can't feel the print on the page."
and i thought to myself, "but that's what i want to do. i love stories. i want to read." little did i know that i would be part of a technological revolution that would make that dream come true.
i was born premature by about 10 weeks, which resulted in my blindness, some 64 years ago. the condition is known as retrolental fibroplasia, and it's now very rare in the developed world. little did i know, lying curled up in my prim baby humidicrib in 1948 that i'd been born at the right place and the right time, that i was in a country where i could participate in the technological revolution.
there are 37 million totally blind people on our planet, but those of us who've shared in the technological changes mainly come from north america, europe, japan and other developed parts of the world. computers have changed the lives of us all in this room and around the world, but i think they've changed the lives of we blind people more than any other group. and so i want to tell you about the interaction between computer-based adaptive technology and the many volunteers who helped me over the years to become the person i am today. it's an interaction between volunteers, passionate inventors and technology, and it's a story that many other blind people could tell. but let me tell you a bit about it today.
when i was five, i went to school and i learned braille. it's an ingenious system of six dots that are punched into paper, and i can feel them with my fingers. in fact, i think they're putting up my grade six report. i don't know where julian morrow got that from. (laughter) i was pretty good in reading, but religion and musical appreciation needed more work. (laughter)
when you leave the opera house, you'll find there's braille signage in the lifts. look for it. have you noticed it? i do. i look for it all the time.
(laughter)
when i was at school, the books were transcribed by transcribers, voluntary people who punched one dot at a time so i'd have volumes to read, and that had been going on, mainly by women, since the late 19th century in this country, but it was the only way i could read. when i was in high school, i got my first philips reel-to-reel tape recorder, and tape recorders became my sort of pre-computer medium of learning. i could have family and friends read me material, and i could then read it back as many times as i needed. and it brought me into contact with volunteers and helpers. for example, when i studied at graduate school at queen's university in canada, the prisoners at the collins bay jail agreed to help me. i gave them a tape recorder, and they read into it. as one of them said to me, "ron, we ain't going anywhere at the moment."
(laughter)
but think of it. these men, who hadn't had the educational opportunities i'd had, helped me gain post-graduate qualifications in law by their dedicated help.
well, i went back and became an academic at melbourne's monash university, and for those 25 years, tape recorders were everything to me. in fact, in my office in 1990, i had 18 miles of tape. students, family and friends all read me material. mrs. lois doery, whom i later came to call my surrogate mum, read me many thousands of hours onto tape. one of the reasons i agreed to give this talk today was that i was hoping that lois would be here so i could introduce you to her and publicly thank her. but sadly, her health hasn't permitted her to come today. but i thank you here, lois, from this platform.
(applause)
i saw my first apple computer in 1984, and i thought to myself, "this thing's got a glass screen, not much use to me." how very wrong i was. in 1987, in the month our eldest son gerard was born, i got my first blind computer, and it's actually here. see it up there? and you see it has no, what do you call it, no screen. (laughter) it's a blind computer. (laughter) it's a keynote gold 84k, and the 84k stands for it had 84 kilobytes of memory. (laughter) don't laugh, it cost me 4,000 dollars at the time. (laughter) i think there's more memory in my watch.
it was invented by russell smith, a passionate inventor in new zealand who was trying to help blind people. sadly, he died in a light plane crash in 2019, but his memory lives on in my heart. it meant, for the first time, i could read back what i had typed into it. it had a speech synthesizer. i'd written my first coauthored labor law book on a typewriter in 1979 purely from memory. this now allowed me to read back what i'd written and to enter the computer world, even with its 84k of memory.
in 1974, the great ray kurzweil, the american inventor, worked on building a machine that would scan books and read them out in synthetic speech. optical character recognition units then only operated usually on one font, but by using charge-coupled device flatbed scanners and speech synthesizers, he developed a machine that could read any font. and his machine, which was as big as a washing machine, was launched on the 13th of january, 1976. i saw my first commercially available kurzweil in march 19xx, and it blew me away, and in september 19xx, the month that my associate professorship at monash university was announced, the law school got one, and i could use it. for the first time, i could read what i wanted to read by putting a book on the scanner. i didn't have to be nice to people!
(laughter)
i no longer would be censored. for example, i was too shy then, and i'm actually too shy now, to ask anybody to read me out loud sexually explicit material. (laughter) but, you know, i could pop a book on in the middle of the night, and -- (laughter) (applause)
now, the kurzweil reader is simply a program on my laptop. that's what it's shrunk to. and now i can scan the latest novel and not wait to get it into talking book libraries. i can keep up with my friends.
there are many people who have helped me in my life, and many that i haven't met. one is another american inventor ted henter. ted was a motorcycle racer, but in 1978 he had a car accident and lost his sight, which is devastating if you're trying to ride motorbikes. he then turned to being a waterskier and was a champion disabled waterskier. but in 19xx, he teamed up with bill joyce to develop a program that would read out what was on the computer screen from the net or from what was on the computer. it's called jaws, job access with speech, and it sounds like this.
(jaws speaking)
ron mccallum: isn't that slow?
(laughter) you see, if i read like that, i'd fall asleep. i slowed it down for you. i'm going to ask that we play it at the speed i read it. can we play that one?
(jaws speaking)
(laughter)
rm: you know, when you're marking student essays, you want to get through them fairly quickly.
(laughter) (applause)
this technology that fascinated me in 1987 is now on my iphone and on yours as well. but, you know, i find reading with machines a very lonely process. i grew up with family, friends, reading to me, and i loved the warmth and the breath and the closeness of people reading. do you love being read to? and one of my most enduring memories is in 1999, mary reading to me and the children down near manly beach "harry potter and the philosopher's stone." isn't that a great book? i still love being close to someone reading to me. but i wouldn't give up the technology, because it's allowed me to lead a great life.
of course, talking books for the blind predated all this technology. after all, the long-playing record was developed in the early 1930s, and now we put talking books on cds using the digital access system known as daisy. but when i'm reading with synthetic voices, i love to come home and read a racy novel with a real voice.
now there are still barriers in front of we people with disabilities. many websites we can't read using jaws and the other technologies. websites are often very visual, and there are all these sorts of graphs that aren't labeled and buttons that aren't labeled, and that's why the world wide web consortium 3, known as w3c, has developed worldwide standards for the internet. and we want all internet users or internet site owners to make their sites compatible so that we persons without vision can have a level playing field. there are other barriers brought about by our laws. for example, australia, like about one third of the world's countries, has copyright exceptions which allow books to be brailled or read for we blind persons. but those books can't travel across borders. for example, in spain, there are a 100,000 accessible books in spanish. in argentina, there are 50,000. in no other latin american country are there more than a couple of thousand. but it's not legal to transport the books from spain to latin america. there are hundreds of thousands of accessible books in the united states, britain, canada, australia, etc., but they can't be transported to the 60 countries in our world where english is the first and the second language. and remember i was telling you about harry potter. well, because we can't transport books across borders, there had to be separate versions read in all the different english-speaking countries: britain, united states, canada, australia, and new zealand all had to have separate readings of harry potter.
and that's why, next month in morocco, a meeting is taking place between all the countries. it's something that a group of countries and the world blind union are advocating, a cross-border treaty so that if books are available under a copyright exception and the other country has a copyright exception, we can transport those books across borders and give life to people, particularly in developing countries, blind people who don't have the books to read. i want that to happen.
(applause)
my life has been extraordinarily blessed with marriage and children and certainly interesting work to do, whether it be at the university of sydney law school, where i served a term as dean, or now as i sit on the united nations committee on the rights of persons with disabilities, in geneva. i've indeed been a very fortunate human being.
i wonder what the future will hold. the technology will advance even further, but i can still remember my mum saying, 60 years ago, "remember, darling, you'll never be able to read the print with your fingers." i'm so glad that the interaction between braille transcribers, volunteer readers and passionate inventors, has allowed this dream of reading to come true for me and for blind people throughout the world.
i'd like to thank my researcher hannah martin, who is my slide clicker, who clicks the slides, and my wife, professor mary crock, who's the light of my life, is coming on to collect me. i want to thank her too.
i think i have to say goodbye now. bless you. thank you very much.
(applause) yay! (applause) okay. okay. okay. okay. okay. (applause)

he great people in history, such as conficius, qinshihuang, dr.sun yat-sen, and so on.
at last, i would like to say, we shouldn’t waste time, life is limited while knowledge is boundless. aha, there is so much to learn. maybe you like reading; maybe you like singing;… maybe you have a lot of other hobbies, it doesn’t matter, if you like it, just learn it. just do it. don’t hesitate. knowledge is power. there is no choice but to learn. what’s more, you are never too old to learn. am i right? my friends, open your eyes, can you see the flame of knowledge burning forever? yeah, i can see it. i can see it clearly. e on, boys and girls, ladies and gentlemen. let’s swim in the ocean of knowledge; let’s climb on the top of knowledge. at that time, you will be a learned person with much knowledge. you will be the happiest person in the world.
that’s all. thank you for you attention.

since the theme of this year’s competition was “globalization”, we have enjoyed various visions from contestants on thinking of what we young people should do to meet the challenges and the opportunities posed by globalization. but there’s one thing for sure: good english and communication skills are the gateway to the world arena. i hope some of man and woman in china who have conquered english to hold hands together to build up the bridge between china and the rest of the world with the world’s most widely used language!

i cant even notice that the mens hands are still raised, and the womens hands are still raised, how good are we as managers of our companies and our organizations at seeing that the men are reaching for opportunitiesmore than women?" weve got to get women to sit at the table.message number two: make your partner a real partner. ive become convinced that weve made more progress in the workforce than we have in the home. the data shows this very clearly. if a woman and a man work full-time and have a child, the woman does twice the amount of housework the man does, and the woman does three times the amount of childcare the man does. so shes got three jobs or two jobs, and hes got one. who do you think drops out when someone needs to be home more? the causes of this are really complicated, and i dont have time to go into them. and i dont think sunday football-watching and general laziness is the cause.
