hi my name's laura bates and i run the everyday sexism project which for anybody who doesn't know what it is is a very simple website that collects people's experiences of daily gender imbalance of anything on the spectrum from the more minor incidents that we're often told to brush off and not make a fuss about all the way through workplace discrimination sexual harassment to sexual assault and even rape i set the project up just under two years ago and we've now received entries from women of all walks 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 it's interesting because people often ask what were the most shocking entries i think they expect me to reply that they were the most serious ones the most harrowing stories of course those were awful and distressing to read but the thing that really shocked me the most was the number of entries we received from really young women from little girls from university students it just wasn't something that i anticipated it's some of those stories that i want to talk about today and to share some of them with you today particularly because we're here in a beautiful university city and because so many of the entries that we've received are suggesting that there's a real problem at uk universities i want to take you through some of the things we've heard about some of the things that are being reported to us over and over and over again this all started and i first noticed a real spike in activity to the website the first time freshers week came around so the first year that the website had been launched in april suddenly when we hit freshers week i noticed there was a massive surge in entries to the project i remember it started i remember it vividly with one email it came from a girl who was about to start studying physics at a very highly-respected london university she forwarded me an email she'd received from the physics society at her university and the email said freshers lunch this will be mainly a chance for you to scope out who's in your department and stake your claim early on the one in five girls she wrote that she was going into an incredibly male-dominated area already and so here the boys in her year her male peers were being sent the message - from a university-affiliated society no less - to view their female peers who were in the minority in this particular course very much as sexual prey this was really just the beginning so many messages and stories started coming in often they were about freshers week and events going on in freshers week so i actually started having a look at the events that were scheduled at uk universities that year you can see behind me these were just a few of the events that i found slag 'n' drag tarts and vicars pimps and hoes golf pros and tennis hoes ceos and corporate hoes rappers and slappers geeks and sluts at almost every event the title sends the message usually at events that were sponsored by or in association with the universities these students were studying at that men are ceos pros geeks they're powerful talented intelligent whilst women were being valued again and again by their sexualization alone the messages we received were suggesting that this created a really serious sense of pressure for young women to dress in a certain way it's important to say this was not about a kind of prudish morality ban it wasn't 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 different ways but every time for the girls there was a very clear very narrow requirement of how they were expected to dress it started to feel like it was about more than just a bit of fun and more like a kind of sexual pressure this idea of sexual pressure was backed up by a lot of the stories we received about initiations and freshers week rituals again obviously this is something that if people want to do they can a

don't let my mask scare you i'm just trying to stay anonymous my name is anamik 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 traveled outside india in neighboring countries in asia my friends have been to africa and we can all agree on one thing in india we tolerate filth on our streets but why we can send a rocket to mars but we can't fix this problem why do we keep our houses clean and our streets dirty even mcdonalds has come to bangalore it's cleaning the steps of its outlet but you can see how dirty it is outside they're either incapable or unwilling to fix what's outside so what's the problem why are we like this and i think all of us in this audience know the answer it's not my problem i pay tax i vote isn't that enough what more should i do some of you will say ok i want to fix it i don't even know how to start let me take you to dream land in dream land there is no corruption the government is strong our budget goes up ten times do you think our cities will be clean what do you think the answer is no i think we all realize it's not about money or systems it is about us as a people look at this picture can someone shout out which city is this from look closely look at the furniture can you guess shout out which city is this it's not bangalore look closely again there's a clue out here the bank of india the other clue is that it's very poorly maintained there are paan stains everywhere this is a restaurant it is singapore and it is little india in singapore and what does this tell us about us what is singapore's brand image cleanliness it is a fine city they enforce laws they are very affluent they care about their look but when a group of indians lives in one neighborhood we seem to bring down the civic standards we can beat the world's best systems i would like to say and i'm an indian we are the undisputed world champions of public filth why do we need a policeman when we have a traffic light because we are a society that doesn't like to follow rules in bangalore dustbins are not allowed you are expected to keep your garbage at home until the collector comes but it doesn't seem to work so one neighborhood in bangalore indiranagar said let's put dustbins so they put dustbins and see what happened we don't like to follow rules so all the garbage is outside the dustbins now this is the problem with us as a society we all need to admit that we are all ugly indians and more importantly only we can save us from ourselves as long as we're emotional about it we won't solve it do you think there is any hope what do you all think a lot of people have given up they leave the country they stay in gated communities but some people said no let us try and fix this problem in an indian way by understanding the indian psychology so social experiments began on church street in bangalore in here the idea was simple let us understand indian's behavior from a point of view of culture behavioral psychology let's 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 we have to be fooled into improving our behavior can we nudge an ugly indian towards better behavior in public spaces you may have heard of the broken window theory which says that if a place is ugly it becomes uglier if a place is beautiful it commands respect there's another theory in economics called the tragedy of the commons which means we care for our private spaces we don't care about our public spaces india is the perfect example of both these theories in action this is koramangala that lady is throwing garbage on the road in a beautiful upscale neighborhood why is she doing it because someone has already thrown before what can we do to make her change her behavior without her knowing it this is a typical example of civic problems in india paan stains on the wall this is on the wall of deccan herald newspaper it has been like this forever because there are paan stains people urinate on it nobody walks on that footpa

transcriber jenny zurawell is e t out there well i work at the seti institute that's almost my name seti search for extraterrestrial intelligence in other words i look for aliens and when i tell people that at a cocktail party they usually look at me with a mildly incredulous look on their face i try to keep my own face somewhat dispassionate now a lot of people think that this is kind of idealistic ridiculous maybe even hopeless but i just want to talk to you a little bit about why i think that the job i have is actually a privilege okay and give you a little bit of the motivation for my getting into this line of work if that's what you call it this thing whoops can we go back hello come in earth there we go all right this is owens valley radio observatory behind the sierra nevadas and in i was working there collecting data for my thesis now it's kinda lonely it's kinda tedious just collecting data so i would amuse myself by taking photos at night at the telescopes or even of myself because you know it at night i would be the only hominid within about miles so here are pictures of myself the observatory had just acquired at new book written by a russian cosmologist by the name of joseph shklovsky and then expanded and translated and edited by a little-known cornell astronomer by the name of carl sagan and i remember reading that book and at three in the morning i was reading this book and it was explaining how the antennas i was using to measure the spins of galaxies could also be used to communicate to send bits of information from one star system to another now at three o'clock in the morning when you're all alone haven't had much sleep that was a very romantic idea but it was that idea the fact that you could in fact prove that there's somebody out there just using this same technology that appealed to me so much that years later i took a job at the seti institute now i have to say that my memory is notoriously porous and i've often wondered whether there was any truth in this story or just you know misremembering something but i recently just blew up this old negative of mine and sure enough there you can see the shklovsky and sagan book underneath that analog calculating device so it was true all right now the idea for doing this it wasn't very old at the time that i made that photo the idea dates from when a young astronomer by the name of frank drake used this antenna in west virginia pointed it at a couple of nearby stars in the hopes of eavesdropping on e t now frank didn't hear anything actually it did but it turned out to be the u s air force which doesn't count as extraterrestrial intelligence but drake's idea here became very popular because it was very appealing and i'll get back to that and on the basis of this experiment which didn't succeed we have been doing seti ever since not continuously but ever since we still haven't heard anything we still haven't heard anything in fact we don't know about any life beyond earth but i'm going to suggest to you that that's going to change rather soon and part of the reason in fact the majority of the reason why i think that's going to change is that the equipment's getting better this is the allen telescope array about miles from whatever seat you're in right now this is something that we're using today to search for e t and the electronics have gotten very much better too this is frank drake's electronics in this is the allen telescope array electronics today some pundit with too much time on his hands has reckoned that the new experiments are approximately a hundred trillion times better than they were in trillion times better that's a degree of an improvement that would look good on your report card okay but something that's not appreciated by the public is in fact that the experiment continues to get better and consequently tends to get faster this is a little plot and every time you show a plot you lose percent of the audience i have of these but what i plotted here is just some metric that shows how fast we're searching in other words we're looking for a nee

what do your digital footprints say about you what do i mean by digital footprint i mean all the stuff that we leave online the digital tracks and traces the stuff that makes up other people's perception of who we are as well as our own some of those things are really visible and some of them are really invisible the things that you've watched the trail of things you've watched on youtube that recommends something else some of them are things like your search history but lots of the things that we leave online is stuff that are entirely within our control and are about our own creative process so i want you to start off by thinking about what the last thing that you shared online was this might've been two or three minutes ago hours ago or days ago what was that last thing that you shared it might have been something on facebook on snapchat - i know i just protected tweeter automatically because i'd like to be a little bit smug when i'm speaking - but what was that last thing what does that thing say about you if someone's looking at that what does that tell you does that tell them what you are or about your interests maybe it says something that's really positive or quirky so again i'm being a bit smug this is baking a bun maybe it shows that you've an interest maybe it shows that you do a particular kind of job maybe it shows a particular kind of hobby that you have or something really positive you'd really want to show to the world so if someone looks at that you'd think brilliant i recognize that person as myself and i think that's what i'd like to portray to people maybe you're portraying different parts of yourself to different kinds of audiences even having different rights by having different kinds of identities for different kinds of contexts so you can present yourself in sort of on-stage ways and off-stage ways just being off-stage and coming on stage - it feels very relevant right now but sometimes you have to have different kinds of identities and they don't always stay totally separate in fact some of the things you share online maybe they're not presenting you exactly how you'd want to do it so this is my polite version of sharing something slightly inappropriate online this is my cat godfrey he's on twitter and instagram please don't judge me or judge me that's ok you might be sharing stuff you don't really intend to get a wider airing godfrey's not to embarrass although i have to say i didn't ask his consent to use his image which i really should've but maybe something gets out of hand maybe it goes to an audience you don't expect it to get to then your identity starts to be this slight model of things intended for different kinds of audiences you get this idea of context collapse where your friends your colleagues people who you run with people who you'd create craft with maybe all converge in the same space they all start to see different parts of your identity and that's quite challenging and when you're sharing on social media that's really likely to happen your parents might be on facebook people you don't know might interact with people who you do know when you're sharing stuff in anonymous spaces you have to be thinking about what that identity is projecting about you and what you want it to project about you it's not about what you share and where you share it it's also who you share it with you can choose but most of us don't choose to we've been doing some research with students at university of edinburgh and we've been asking them to tell us how they use social media how they think about their identity online and of them very very rarely check their privacy settings and five percent of them have found something online they did not want to see they thought it's been taken away they didn't think they posted it so privacy settings who you share with and the circles you share with matter you share to these networks they share further on you have control of that but most of us choose not to exercise that and that's kind of interesting so we have these footprints we have these things that are visib

my name is james and i'm an experimental particle physicist that means that i get together with 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 into each other to see what happens the reason we do this is because we're looking for things that mankind has never seen before at the very fundamental physical scales i'm here to share with you what something called a dark photon is but to do so i need to set a little bit of historical context - that was an unsuccessful clip there we go - i need to set a little bit of historical context to flashback to when the eminent physicist albert michelson said the following -- he stood in front of an audience at the university of chicago and he said the more important fundamental laws and facts of physical science have all been discovered and these are now so firmly established the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote a couple of decades previous electricity and magnetism had been shown to be two parts of the same force electromagnetism this was considered such a gigantic breakthrough there was a prevalent attitude amongst a lot of physicists that this was pretty much it and the rest were some minor details sometimes i wonder if people like this - michelson didn't need to he was about to get the nobel - say things like this with such definitive authority just so they cab ensure their place in history as grand historical straight men so we can look back years later and marvel at how completely wrong they were a different albert - special relativity general relativity and then in the early decades of the s quantum mechanics then the need to unify quantum mechanics with relativity led to quantum field theory any one of these things by themselves required a complete paradigm shift in our understanding of nature at its very basic scales that it's hard to imagine how michelson could have been more wrong in his pronouncement this quantum field theory that we came up with was the language that allowed us to understand -- had this amazing interplay between theory and experiment in physics in the th century that culminated in this thing that we call the standard model of particle physics it's essentially a list of all the fundamental particles we know and the ways they interact it's nicely summarized in this diagram from the movie particle fever it doesn't have any significance beyond it it's a just a really nice way to put it down on a slide essentially you have two basic classes of particles you have the outer ring which is matter particles and they are quarks and the electron and you have this inner ring which is populated by the so-called force carrying particles or gauge bosons it's an almost shockingly successful experimental theory -- so much so that it earns that name the standard model capital s capital m maybe a few ears may have perked up when i said that word boson anyone here heard of the higgs boson for those of you who haven't heard of the higgs boson perhaps you know it by its more sensationalist name the 'kanye particle' -- sorry the god particle physicists don't care much for that name because it obscures the truly awesome nature of this particle but nonetheless in july of two of the collaborations two of the experiments at the large hadron collider - atlas the one that i work on - and cms a complimentary experiment at the large hadron collider at cern near geneva announced the discovery of this brand new particle the higgs boson its discovery is an amazing triumph it was the culmination of decades of work by thousands of physicists and it really was a fantastic triumph it was the last remaining piece of the standard model puzzle to be plugged in so you might think that once this was plugged in we all turned to each other and said wow isn't this great finally years later we've finally reached michelson's dream of end of physics is this what we said to each other absolutely not we know for a fact the st

my name is marcus buehler i'm the mcafee professor of engineering at mit and i'm also a member of the center for computational science and engineering in the schwarzman college of computing in this talk i'll be talking about the nexus of materialized sound and sonified material we're going to be talking about how vibrations sound and matter interact and how we can use music to design new and better materials if we're thinking about biological structures such as a spiderweb we can see they're very detailed very intricate very complex structures if we look in a spiderweb - in this case a d spiderweb - there are many internal structures that go really from the macroscale all the way down to the nanoscale we're now flying inside the web structure and we can see that this web has very complex architectural features as we go closer we see more and more of those architectural features emerge and become visible if we go even closer we can look inside each of the silk filaments we can recognize that each silk filament itself consists of a hierarchical structure this hierarchical structure ranges from the molecular scale the individual protein molecules which are assembled atom by atom to form secondary structures to form tertiary structures to form bundles of proteins ultimately forming filaments assembling into bundles of filaments and fibrils then forming the filaments the silk fibers that you can see in the web so you can see that the web structure really has a structure that goes from the macroscale all the way down to the nanoscale how are these materials built well these materials are built in nature by encoding structural information through the genetic sequence usually encoded by dna these dna letters encode information about how proteins are built proteins are built from primary sequences these genetic information letters forming sequences of amino acids forming secondary structures such as alpha helices or beta sheets and these in turn form more complicated structures such as collagen in our bones spider silk consisting of beta sheets and alpha helix mixtures to also more complex structures like viruses what you see in this slide in this picture here is a pathogen of covid- which has these spike proteins sticking out on the surface which give this virus its name the coronavirus or crowns this coronavirus is encoded by sequences of amino acids encoded by letters of rna or dna genetic information this genetic information provides the building plan for how this virus is actually built just like the virus is built from the bottom up forming hierarchical structures across different length scales and time scales we also know that in engineering we might be able to use such an approach as well thinking about an architectural system like the eiffel tower you can also recognize that this system has features as well that go from the macro- all the way down to the nanoscale even though engineers have been using hierarchical principles for an extended period of time we have not yet been able to tune simultaneously molecular scale all the way to the macroscopic level one other feature that's really interesting is a unifying theme and feature across different manifestations of matter and that is the equivalence of vibrations to matter to sound the universality of waves and vibrations is something we see in molecules we can recognize that at the quantum mechanical level we can describe matter as collections of waves we can also see that sound is an overlaying of sine waves harmonic waves to create more complicated sound structures and we can also see that spiders for instance use waves as a way of communicating and understanding the environment waves sound vibrations are universal and we can use perhaps vibrations and sound as a way of defining material models optimizing materials and even inventing entirely new materials by using vibrations here we show how we can evolve the way hierarchical systems are built thinking about a spider a spider uses vibrations as a way of sensing the environment communicating with other spiders sensing

i'd like to start by asking you to imagine yourself in the following scenario you are a high school senior or the parent of a high school senior and you're 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 habit everybody you see is smoking outside everybody smells like cigarette smoke in fact you go to have lunch in a dining hall and students are actually bragging about how much they smoke one student says yesterday i smoked three packs all by myself and another student says nice i did that last week high five and you think to yourself well this is pretty strange this is an otherwise great school but they have sort of a weird bad habit and they're oddly celebrational about it so i'm not sure i want to go here so imagine you go on a second campus tour and you look at a second college and it's very similar to the first the campus looks really beautiful people are friendly - except this college has a bad junk food habit everybody you see is eating junk food there's junk food wrappers 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 five so if these two scenarios sound a little far-fetched imagine a third scenario as you go visit another college and again it looks really great the people are friendly except that at this college everybody looks tired you see people falling asleep at their computers you visit a class and people are dozing off in class and it just generally looks like everyone could use a great nap right so what's crazy to me about this is that i've never seen a campus full of people who are all smokers or a campus full of people who are all sleep-deprived but a campus full of people look tired and - or sorry a campus full of people who all eat junk food but a campus full of people who are all sleep-deprived and tired describes every college and university i think that i've ever seen and actually most high schools as well especially during later parts of the semester what's interesting is that the effects of being sleep-deprived all the time can be just as bad as smoking and just as bad as eating 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's a really hard-working college where people are very productive and achieving great things and so as a sleep researcher i've been fascinated by the biology and neuroscience of sleep for over a decade and i have a lab at williams college that studies mice we look at what happens in the brain and the body during sleep we look at how the neurons in the brain control sleep but i have to say as a father as a teacher and as a colleague to a lot of hard-working colleagues hard-working people i have a new-found fascination for how we tolerate sleep deprivation as a society and it's not just students in our schools it's really everywhere whenever a ride public transportation whether it's a bus or a subway i see people who just look exhausted and in fact you can see people taking naps on their morning or afternoon commute and sneak them in in our public life it's really not uncommon to see people dozing off and in general in our public and professional lives people really just look exhausted but something 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 as a badge of honor right because 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 very productive or else why would you be sleep-deprived in the first place i've actually been a part of job committees where job applicants will brag about the
