WHEN we were 16 years old, my friend Karen and I were interviewed for an educational video. With our hair thick with styling mousse, pale blue eyeliner and misplaced teen swagger, we explained why we had chosen to study physics. We were the only two girls in our school that year who had. Our video was going to inspire other girls to do the same. We were going to change the world.
Thirty years on, it is safe to say our ambition failed. In 2016, in almost half of the schools in England that admit girls. In the same year, just one-third of schools had two or more girls taking the subject. It is a similar picture across much of the world. Despite all the initiatives to attract more girls into physics, the proportion remains stubbornly low.

Physics and sexism has been thrust into the spotlight in recent weeks by the incendiary comments made by theoretical physicist Alessandro Strumia. At a workshop on gender in physics, of all places, at CERN near Geneva in Switzerland, he claimed that women were less capable than men at physics research. The day after he was suspended by CERN, Donna Strickland became only the third woman to receive the Nobel prize in physics in its 117-year history, sharing this yearâs award for her pioneering work on lasers.
All this paints a picture of physics as a career that is unwelcoming to women to start with and isolating for many of those who do make it. But why is this still the case in 2018 â and what can we do about it?
Letâs get one thing straight. Girls are just as capable as boys at physics. You donât need brain scans to tell you, just look at the exam results. âGirls perform at least as well, if not better,â says Charles Tracy, head of education at the Institute of Physics in the UK. This year, achieved the highest two grades at A level â typically taken by 16 to 18-year-olds â compared with 29.5 per cent of boys. And it isnât that girls donât study the subject. In 2018, just over at A level, compared with around 6000 who picked French.
The problem is that this is minuscule compared with the 29,400 boys who chose it (see âGraphâ). Physics was the second most popular subject for boys at A level, yet the for girls. âMany girls who could have had careers in physics are dropping out. Itâs a terrible shame that weâre losing that amount of talent,â says Julia Higgins, president of the .
Something seems to be happening around the age of 16. Up until this point, most girls who have studied science have physics in their top four grades. But then they quit. Why?
For almost 20 years, the Institute of Physics has been trying to find out. âWhen we started looking for reasons why, we found that there was little evidence,â says Higgins.
At first, the institute thought it was to do with sexism and stereotypes within physics teaching. Initiatives to address these issues had some success, . But then the improvements shuddered to a halt. The institute began to suspect that the problem wasnât with physics teachers or even science departments, but a problem with the entire school.
What followed was exploring the issues. Starting in 2014, 26 schools took part in a two-year study that took four different approaches. The first group of schools worked on improving the confidence of 13 and 14-year-old girls. A second group focused on working with physics teachers. A third worked on tackling the culture of the schools as a whole by involving teachers, governors and students from every subject, not just science. The final group of six schools took part in a pilot project funded by the Drayson Foundation that blended these three approaches and tailored them to fit an individual schoolâs needs.
The results were positive in all cases, but what really stood out were the outcomes from the Drayson schools. The number of girls starting A level physics more than trebled in two years, soaring from 16 to 52. âWe looked at physics and itâs not the physics, itâs the environment,â says Higgins. The Institute of Physics now plans to roll out a larger version of the Drayson pilot to 100 schools in England, starting in March 2019.
Even if we tackle the problem of getting girls to opt for physics at school, they still face issues as they progress further through their careers. Karen and I parted ways when we left school. She studied geology and I went to study physics at the University of Glasgow. While men outnumbered women, I certainly wasnât alone. About 20 per cent of the undergraduates were female, a number that is typical in other countries, including the US.
One exception is Iran, where 60 per cent of physics undergraduates are women. âSome of the Middle Eastern countries provide well-balanced opportunities with segregated education,â says Gillian Butcher, who chairs the . âBut the opportunities post-education are then limited, restricting women to be the educators for the next generation of women.â
Most countries have issues somewhere along the line, says Butcher. These can include limited career prospects or a hostile environment at work. âWomen face a massive set of obstacles at every stage of their career,â says , a Royal Astronomical Society fellow at Imperial College London.
For instance, research shows that women in science are more likely than men to have their about potential PhD positions. And, on average, they need to have published than men to get the same academic job. And they are . These issues arenât unique to physics: women face them across science.
To find out more about physicistsâ everyday experiences, the American Institute of Physics surveyed 15,000 people from 130 countries. It was the first survey of its kind to they need to carry out research and present their results. Without adequate funding, lab space, travel budget and students to help with research, for example, a researchersâ career can stall. Meanwhile, experiences, such as being invited to speak at a conference or serving as editor of a journal, can help to advance a career.
The survey revealed that women were worse off than men on every single measure. And while there were differences between highly developed countries and those lower down the scale, the brakes are being put on female physicists all over the world. In the UK, for example, just 17 per cent of physics lecturers are women and that drops to just 7 per cent of professors. In Italy, only 8 per cent of physics professors are women.
This adds up to a constant battle for women trying to forge a career in the field. âItâs the isolation women feel, itâs the unconscious biases, being made to feel youâre inadequate,â says physicist Jess Wade at Imperial College London. âFighting diversity battles on top of your research, itâs exhausting.â
In September, Wade spoke at a workshop held at CERN for women at the start of their physics careers. The event focused on recent developments in theoretical high-energy physics and cosmology, such as dark matter, black holes and neutrinos. There were also talks dedicated to research on gender in academia with the aim of developing an action plan to support women in physics.
However, the workshop was overshadowed by the talk by Alessandro Strumia, who argued that the main reason there are more men in theoretical physics is that women are inherently less capable of physics research than men. Whatâs more, he claimed that the biases in physics worked in the favour of women, and against men.
âHow do we steer away from advertising physics as the place for genius?â
His arguments have been branded âmorally reprehensibleâ in an . The letter debunks each of Strumiaâs claims. For example, he argued that men are intrinsically better at physics because they have written the papers that are most frequently referred to in work by other researchers. This is an absurd proxy for quality, particularly in particle physics where the number of authors on a paper can easily reach into the thousands due to the practice of listing every member of a collaboration. The paper that detailed the discovery of the Higgs boson in 2012, for example, . Many of them will have contributed little towards that particular analysis.
The other issue is that Strumia ignored research showing that there is a bias in the way that authors reference other researchersâ work. Papers by female authors are routinely ignored in favour of ones written by men, .
In the spotlight
Women who called out Strumiaâs talk, such as Wade, found themselves the target of online abuse. A common call was for women to provide evidence that Strumia was wrong.
This kind of retaliation is also why so many women in physics who are on the receiving end of sexual harassment are unlikely to formally complain about it, according to a review by the US National Academies of Sciences, Engineering and Medicine this year. Several cases have come to light recently of male physicists sexually harassing their female students, and of universities being atrociously slow to act. The review also found that of female lecturers and staff at academic institutions have been sexually harassed.
Despite the grim headlines, particle physicist at Brunel University in London believes that the problems in physics are no worse than in any other male-dominated subject.
And times are changing for the better, says Cole. Spotlights are being shone on issues that were once covered up and these issues are now being dealt with. âThese days, people are more aware of diversity issues in physics. People are taking it more seriously.â All of the collaborations working on the four experiments at the Large Hadron Collider in CERN have a diversity committee, and in 2010 CERN introduced its first code of conduct that all staff, including visiting scientists, are expected to follow.
Funding organisations are starting to take bullying and harassment seriously, too. In the biomedical sciences, the Wellcome Trust, for example, requires the organisations it supports to have clear policies in place and will withdraw funding from organisations and individuals found guilty of bullying.
For women working in physics, finding female mentors who might have gone through the same challenges can be a huge help, says Samaya Nissanke at the University of Amsterdam, in the Netherlands. âFeeling that you are not alone and that you can discuss the challenges that you face on a day-to-day level has made the world of difference to me,â she says. Men too can make powerful advocates.
âMy own success would not have been possible without my fantastic mentors, most of whom have been men,â says theoretical physicist Tracy Slayter at the Massachusetts Institute of Technology. She encourages male colleagues to speak up when women are treated or discussed in ways they disagree with. âYour voice has power, in part because of your gender,â she says.
We also need to shake off the idea that physics is a place for the lone genius, says Ăgnes MĂłcsy, at the Pratt Institute in New York.
Given the challenges, why would girls thinking about a career in physics stick it out? Simply because the rewards can be huge. âI often get feedback from young people saying that meeting me and hearing about my job made them realise that this subject could be for them too â to be part of something big that will improve our future, to travel the world, to make a difference,â says Ceri Brenner, a laser physicist at the Science and Technology Facilities Council, UK. âYou can have a fulfilling life. Of course this comes with a little bit of compromise, but which career doesnât?â
Some Anonymous Real-Life Experiences from Women In Physics
⢠An influential colleague once tried to convince me that itâs OK to have fewer women in physics because our brains are just intrinsically different. He helpfully suggested I go read the literature on it
⢠I was greeted with wolf whistles and stamping feet when going into a physics lecture
⢠Colleagues tell me that I only got the promotion to professor because I was a woman
⢠Iâm often mistaken for the groupâs secretary
⢠I was talking to a group of male colleagues at a physics conference when one man walked past and groped me. None of my colleagues challenged him
⢠I was told not to change my name when I got married because it would affect my publication record when I got divorced
⢠When I make a mistake, Iâm made to feel that itâs because women canât do physics. I carry the responsibility of the entire gender
⢠I watch what I wear so that Iâm taken more seriously
Best in Class
Girls turn away from physics around the age of 16 (see main story), but one school that is bucking the trend is Kendrick School in Reading, UK. This state-run girlsâ grammar school has 270 pupils in its final two years. Of them, 79 are studying physics. In comparison, 68 per cent of schools that admit girls in England, Wales and Northern Ireland have no more than one girl studying physics.
The motto at Kendrick is physics is fun. It might sound trite, but the schoolâs head of physics, Theresa Conlon, aims to get pupils living and thinking about physics without feeling under pressure.
The pupils run their own weekly science clubs. They are a way for like-minded students to get together, exchange ideas and encourage each otherâs interests. âThey donât feel geeky, or isolated,â says Conlon. âThereâs no negativity about physics or engineering.â

What can we do about it?
Some views from women in physics on how to tackle the problems facing the field
⢠We need more role models, and we need to support each other.
⢠I begin and end a lot of my outreach talks with a message that I borrowed from Albert Einstein â âimagination is more important than knowledgeâ â with the intention of raising discussions about the role of creativity and imagination in physics, as I really believe these are our core skills. And in highlighting these as being as important as technical skills and knowledge, then we will attract and retain a more diverse, proactive, progressive and effective physics community.
⢠There are various studies showing ways of increasing diversity in physics hires, including having objective criteria defined in advance, having a diverse hiring panel and hiring a group of people at once instead of one by one.
⢠It isnât enough to just increase the number of women and think that is the problem solved. We also need to change our unconscious attitudes. Bring the unconscious biases into the conscious. This process takes effort and it can be uncomfortable, but it is necessary.
⢠Talk to women about their science â not the biases they face. After all, they are in physics because they are good at it and enjoy it. Credit their work, amplify their voices and donât steal their ideas!
⢠We need to ensure that girls and boys are brought up in a gender neutral way all through their lives, so that girls are just as likely to be given toys that require them to think about shape and geometry (and boys given toys that bring out their interpersonal skills), and encourage them to build and create, to use their imagination.
⢠Addressing systemic problems such as sexual harassment is a must.
⢠We need UK schools to delay decision time about discipline choices and to enable a broader range of subjects to be studied till 18. By the time students start at university, we already see a grossly imbalanced sex ratio in the lecture theatres. It is hardly surprising there arenât equal numbers at the top.
⢠How about we start steering away from advertising physics as the place for genius? Instead tell the true story: that we go through physics with hard work and effort, that we accomplish things through being in constant âwork-in progressâ mode.
⢠I think the question of salaries and power is much more urgent to tackle than the one about the interests of boys and girls. Today, more and more girls are encouraged to develop an interest in physics, but they will find the same career struggles as their grandmothers if we donât consider the role of women in society at large.
⢠Those of us with power and influence in our field â physicists of all genders, not only women â need to be willing to push back when our colleagues or institutions reinforce harmful messages, deliberately or not.
⢠One new strategy that several groups are working on at the moment is to talk science with young parents at baby and toddler groups. By reaching out to a new audience that wouldnât normally connect with science, we can explain that science and maths really arenât any harder than other subjects. Science is utterly awesome and absolutely for everyone, not just for boys. These parents can then become the role models, encouraging, not discouraging their own children from fulfilling careers in science.
⢠Women need mentors who are truly in their corner. Women of colour need mentors who look like them. Black and indigenous women and gender minorities are for the most part denied the opportunity to have a mentor who shares their gendered and racial identities.
⢠Senior figures should work hard to fix legacy problems so that the weight doesnât fall on junior scientistsâ shoulders. Both men and women need to do this â it isnât a womenâs problem for women to fix.
⢠More discussion about bullying and harassment, which are still not openly discussed in the physics community, is needed to increase awareness and develop official methods to tackle them, where the burden doesnât lie on women who are making the complaints.
