hi my name floora bates and i run the everyday sexes and project which for anybody who doesn't know what it is is a very simple website that collects people's experiences of daily gender inbalance hav anything on the spectrum from the more minor incidents that were often told to brush ff and not make a fuss about all the way through workplce discrimination sexual harassement to sexual assaut and even rapei set the project up just under two years ago and we've now received fifty thousand entries from women of all warks of life all over the world but one thing really shocked me and took me aback about the entries that started to flood in in the first months of the project and it's interesting because people often ask you know what were the most shocking entries and ithey expect mto reply that they were the most serious ones most harrowing stories and of course those were awful and distressng to read but the thing that really shocked me the most was the number of entries hat we receive from really young women from little girls from university students it just wasn't something that i anticipatedand its some of those stories that i want to talk about today and o share some of them with you today particularly because w're here an are beautiful university city and because just so many of the entries that we've received a suggesting that there is a real problem at yuk universities i want to take you through some of the things that we've heard about some ofthe things that are being reported to us over and over and over againso this all really started and i kind of first noticed o ral spikin activity to the website the irst time that freshesweet came round so the firs year that the website had been launched in april and suddenly when we hit freshsweek i noticed that it was a massive surge in entries to the projectand i remember it started i remember really vividly with one email and it came from a girl who was about to start studying physics at a very highly respected london university and she forward me forded me in email that she'd receive from the physics society at her university and the email said fresh s lunch this would be mainly a chance for you to scope out who's in your department and stake your claim early on the one in five girlsbut she wrote that she was going into an incredibly el-dominated area already and so here the boys in her year here male peers were being sent the message from a university affiliated society no less to view that female peers who were in the minority in this particular course very much as sexual prey and this was really just the beginning nd so many messages and storys started coming in and often they were about freshs-weeken events that were going on in freshas week so i actually started having a look at the events that were scheduled at yuk universities that yearandas you can see behind me these register few o the events that i found slaggon drag tots and vicas pimps and hos gol prose and tennis hos se yos and corporate ho rappers and slappers geiks and sluts and at almost every event the titlesends the message usually at events that were sponsored io an association with universities at these students were studying at that men are ceo's pros geeks they're powerful theyr talentd their intelligent whilst women were being valued again and again by their sexialisation aloneand the messages we received wase suggesting that this created a really serious sense of pressure for young women to dress in a certain way and it's important to say at this point that this was not about a kind of predish-morality ban it wasn't about saying women shouldn't dress in that way if they wanted to but why should it be a requirement it felt like fancy dress for the boys meant something fun meant dressing up in a whole variety of diferent ways bed every time for the girls the was a very very clear very narrow requirement of how they were expected to dress and it started to feel like it was about more than just a bett of fun and more like kind of sexual pressur and this idea of sexual pressure was really backed up by

ien sien e ton e te tis varited the tibates dimin eas divin lineedon't let my mask scare you i'm just tryin to stay anonymous my name is anamic nagrik i'm a proud indian and i have one problem with my country and the problem is why is india so filthy i've travelled outside india in neighboring countries in asia my fiends have been to africa and we can all agree on one thing in india we tolerate filt on our streets but why we can send a rocket to mars but we can't fix this problemwhy do we keep our houses clean and our streets dirtyeven mcdonalds was comin to bangalore iscleaning he steps of its outlet out therebut you can see how dirty it is outside are either incapable or unwilling to fix wats outside so what's the problem viabe like his and i think all overs in this audience know the answer it's not my problem i pay tax i wote isn't that enough what more should i do and som of you will say oky i want to fix it i don't even kno how to start let me take yout to dreamland in this dreamland there is no corruption the government is strong a budget goes up ten times do you think our cippies will be clea what doyou think and the answer is no i think we all realize it's not about money or system to tell it is abot us as a people look at this picture can someone shout out which city us this frorm look closey look at the furniture can you guess shout out which city is thisit's nout bangalorelook closely again to the clue out here at the bank of india the other clue is that its very poorly maintained there are pan stains everywhere this is a restaurant it is singapore and it is little india sinaporeand what does this tell us about us what a singapore's brand image cleandliness itis a fine city the enforced laws they very affluent they care about their look but when a group of indians lie in one neighborhood we seem to bring down the civic standards we can beat the world's best systems in fact i would like to say and iam an indian we are the undisputed world champions of publi filthwhy do we need a policeman when we have a traffic light because we're a society that doesn't like to follow rulesin banglo dusbins are not allowed you're expected to keep hour garbage at home till the collector camps but it doesn't seem to wor so vane neighborhood and banglor indraniker said let's put dusbins so they put dusbins and see what happened we don't like to follow rules so all the garbages outside the dusbinnow this is the problem without a societywe need to all admit that we are all ugly indians and more importantly only w can sae us from ourselves and as long as we ary mosle about it we won't solve it and so do you think there s any hope what doyou'll thinka lot of people i've given up to leave the country the stangated communities but some people said no let us trian fix this problem in an indian way by understanding the indians psychology and so social experiments began on church stret in bangalor in two thousand ten but the idea was simple let us understand indians behavior from a point of view o culture behavioral psychology let see what it takes to make an ugly indian change but most importantly without him or her realizing it we don't like to be told what to do yoet we falled into improving our behavior can be nudge and inagly indian towards better behaviour in public spaces you may hve heard the broken windows theory which says that if a place's uggly it becomes uglier to places beautiful it commands respect there is another theory in economics called the tragedy of commons hich means we care for our private spaces we don't care about public spaces india is a perfect example of both these theories in action this is coromangula that lady is throwing gubbage on the road in a beautiful part of an ubscale neighborhood and whys she doing it because someone is already thrown beforewhat can we do to make her change her behaviour without her knowing itthis is a typical example of civic problems in india pan stains on the wall this is on the wall of decconhered newspaper an church street it has been like this forever because there spanstains

econposin holteie poju ite doting hatiejonian jane ii aweniams james and i'm experimental particle physicis in what that means is that i get together wth a few thousands of my closest colleagues and we take the smallest possible things in nature and we accelerate them up to the highest possible speeds and we slam them inoeach other to see what happensreason we did this is because we'relooking for things that mankind has never seen beorevery fundamental physical scalesand so i'm here to share with you what someoniy alled a dark photon is but to do so i ed to set a lttlebit of historical context unsuccessful click lering u i ed to sait a littlebitof a historical context andflashback to eighteen-ninety-four when eminent physicist albert michaelson said the following he stood in front of audiences froat the universit of chicago and he said the followingthe more important fundamental laws and facts of physical science have all bee discovered and these are now so firmly established at the possibility of their ever being supplanted in consequence of new discoveries is exceedigly remote a couple of decades previous electricity of magnetism had been shown to be two parts of the same force electromagnetism and this was considered such a gigantic rake hrough hetime thatthre was a prevalent attitude amongst a lot of physicst that this was petymuturet andthe rest were some minor details but sometimes i wonder if people like thi michaelson didn't needto because we've gat to get the nobel but i wonder somtimes if people saythings like s with such defenditive authority just so they can ensure their place and history as like grand historical straiteman so tht we look back a hundred years later and mrvel at how completely wrong they were a different albert nineteen-o-five special relativity nineteen-fifteen geeral relativity and in their early decades of the nineteen-hundreds quantum mechanics and thn thy ned to put quantum mechanics together with relativity led to something called quantum field theory andanyone of these things by themselves required such a complete paradime shifton or understanding of nature tats very basic scales that it's hard to imagine how michaelson could have been more wrong in his pronouncenso this a quantum field theory that we ame up with was wastelanguage that llowed us to understand is amazing interplay between m theory and experiment in paricle physics and physics itwentieth century that culminated in a thing that we call the standard model of particle physics and sits is essentially a list f all the particles e fundamental particles we know and the ways thatthey interact and its nicely summarised in this diagram from movie particle fever it desn't have any significance beyond its just really ce way to put it down on slide and essentially have two basic classes of particles yo have the outer ring which is matter particles and there are a qorx in electron and they have thes inner ring which which populated by the so-called force carrying particles or gauge bos onsandso thisi it's a amazing most shockingly successful experimental thersoch so that i actually earns that name the standard model capital s cpitalmimanddia utmaybe a fw ears may have prirked up when i said that word bows n one hered heard ofthe higs bows-onho haven't heard of the higs boson perhaps you know by its more asensationalistic name the kanye particles sary the god particlesophysicis don't care much for that name because it obscures the truly awsome nature of this particle butonetheless in a july of two thousand twelveskis may toed the collaboration to the experiments at the large adron collidor atlas the one that i work on and see amas a complementary experimentits he large headrun clliter at sern near genevaannounced the discovery with his brand new particle the the higgs bozon iois its thculbist discovers amazing triumph with a culbination of decades of work by thousands of physicists and it really was it really was a fantastic triumph wastelast remaining piece of the standard model puzzle to be pluged inand so you might think that hen on

dobut i'd like to strt by asking you to imagine yourself in the following scenarioyou are a high school senior or the paren of a high school senior and youare interested in a potential college and so you arrange for a campus visit and you go on a campus tour and everything looks great and the people are friendly but after a few minutes something strange starts to dawn on you that this campus has a really horrible smoking habiteverybody you see is smoking outside everybody smells like cigarette smoke infact yugota have lunch in a dining hall and students are actually bragging about how much they smoke one student says yesterday i smoked three packs ll by myself and another student says nice i did that last week high five and you think to yourself well this is pretty strange thit's anotherwise grea school but they have a sort of a weard bad habit and they're oddly celebrational about it so i'm not sure i wantno go hereso imagine you go o a second campus tour look at a second college and it's very similar to the first the campus looks really beautiful people are friendly eccept this college has a bad junk food habiteverybody who sees eatingjunk food there's junk food rappers everywhere there's nothing nutritious to eat in the dining hall and again people are bragging about how much they're eating so one student says last night i had a whole pizza by myself and another student says nice i did the same thing last week high fiveso if these two scenario stound a little far fetched imagine a third scenario is you go visit another college and again it looks really great the people are friendly eccept at this college everybody ooks tiredyou see people falling asleep at their computers you visit a class and people are dozing off in class and just looks generally like everyone could use a great nap ihtso what's crazy to me about this is that i've neverseen a campus ful of people who are all smokers or a campus full of people who were all sleep deprived campus ful of people who look tired and sleep rtia campus full of people who are all eate junk food but a campus full of people who are all sleep deprived and tyred describes every colleg and university i think that i've ever seen and actually mos high schools at wells especially during later parts of fthe semester and what's interesting is that the effects of being sleep deprived all the time can be just as bad as smking and just as bad as any too much junk food and yet lots of students would actually choose to go to a college where everyone looks sleep deprived because it looks like it really hardworking college where people are very productive in achieving great thingsand so as a sleep researcher i've been fascinated by tbiology and neuroscience of sleep for over a decadeand i h've a lab at williams ollege that studies mice we look at what happens in the brainanbody during sleep we look at how the neurons and bain control sleepbut i have to say as father as a teacher and as a colleague to a lot of hardworking colleagues ardworking people inufound fascination for how we tolerate sleep deprivation is as a socyand it's not just students in our schools o it's really everywhere whenever i ride public transportation whether it's a bus or a subwayi see people who just look exhausted and in fact ou can see peo ple taking naps on their morning or afternoon commute and sneak them inand in our public life it's reall not uncommon to see people dozing off and in general in repulicprofessional lives pople really just look i'm exhausted is even crazier than that to me which is that not only are people exhausted but some people choose to be sleep-deprived and some people actually wear it is a badge of honor htcause in order to be sleep deprived you must be really hard working you must have a lot of important things to do and you must be very vry productive or else why would yu be sleep deprived first placei've actually been a part of job committees where job applicants wll brag about the fact that they only get three or four hours a sleep at night actually just a couple months ago i was looking a
