Exam revision workbooks used by GCSE pupils taking Welsh exam board qualifications have been withdrawn after 90 mistakes were found in them.
A team from Cardiff University’s School of Mathematics found about every three in 50 questions contained an inaccuracy, were misleading or supplied a wrong answer.
Publisher Hodder Education is now reprinting the edition and has asked for current copies to be destroyed.
BBC research had led to the discovery.
The One Show commissioned Cardiff University to look at Mastering Mathematics for WJEC GCSE Practice Book: Higher alongside workbooks for five UK exam boards: WJEC, AQA, Pearson/Edexcel, SQA and OCR, some of which had officially endorsed the books.
Hodder Education apologised for the mistakes.
Group managing director Lis Tribe said: “We are human. We do our best. We have made a mistake.
“Where our process fell down, which is a real concern to me and to my team, is that there wasn’t the final quality check that should have taken place. We simply missed a stage because of the pressure of getting the book out on time.
“We are actually very grateful to The One Show for bringing these errors to our attention and enabling us to withdraw the book and put them right.”
A spokesman for the WJEC said: “We have worked with Hodder to produce endorsed material. However, we have not endorsed the revision guide in question.
“As it has not been subjected to our endorsement process, we are not responsible for its content and cannot comment on it.
“Of course, if we are made aware of any errors in non-endorsed publications, we make every effort to ensure that the relevant publisher is informed.”
Dr Matthew Lettington, who oversaw the research, said the level of mistakes was “unacceptable” and some errors would have been “highly confusing” for students.
The WJEC practice book had the highest level of errors by a significant margin, with 90 mistakes out of 1,496 questions.
The others were:
The exam boards told the BBC final responsibility for fact checking lay with the publishers.
Pearson/Edexcel said it had already spotted and corrected the eight errors in its workbook and it was being recalled and destroyed.
Cambridge University Press and Oxford University Press both said all errors were looked into and corrected in the next reprint.
The One Show is broadcast on BBC One at 19:00 GMT.

And then there were five. From an initial 16 teams, five have moved ahead into the final stages of the Google Lunar XPRIZE, a competition to launch and land a rover on the Moon by the end of 2017.
The finalists herald from around the world, in Israel, the US, India, and Japan. All of them have launch contracts on various rockets, in an attempt to scoop the $20 million prize money. The first teams rover to travel 500 meters (1,640 feet) on the lunar surface will scoop the prize, with various other technical bonuses available.
Each of these teams has pushed the boundaries to demonstrate that you dont have to be a government superpower to send a mission to the Moon, while inspiring audiences to pursue the fields of science, technology, engineering, and mathematics, said Chanda Gonzales-Mowrer, senior director of Google Lunar XPRIZE, in a statement.
The competition began in 2007, and the teams that entered had until December 31, 2016, to get a launch contract, which 11 teams did not manage including German team Part-Time Scientists, who were seemingly on the cusp of doing so. Now, those with launch contracts haveuntil December 31, 2017, to actually launch although they can land on the Moon at a later date, as long as they have launched before then.
XPRIZE also announced there would be an additional $1 million Diversity Prize split among the 16 teams to recognize each of their unique approaches and initiatives over the years, said Gonzales-Mowrer.
Part-Time Scientists had hoped to revisit the Apollo 17 landing site with their rover (illustrated). PTScientists
Of the five finalists, only three have launch contracts on tried and tested rockets. One of these is SpaceIL from Israel, which plans to launch on a SpaceX Falcon 9 rocket. Another, Team Indus from India, is planning to launch on the Indian Space Research Organizations Polar Satellite Launch Vehicle (PSLV). And Hakuto, from Japan, plans to hitch a ride with Team Indus.
The other two have contracts with companies that are yet to launch a rocket perhaps making them relative outsiders to win the competition. One is American team Moon Express, which has a multi-mission contract with Rocket Lab USA to launch three missions by 2020. The final team, an international endeavor called Synergy Moon run by Interorbital Systems, hopes to launch on their own Neptune 8 rocket, which would launch from the sea.
Theres plenty of cause for excitement, though. Its looking more and more likely that some of these teams will actually launch by the years end. Whether they will be successful in landing on the Moon or not remains to be seen none have experience indoing so.
But if they do make it, well, we might very well have an old-fashioned Moon race on our hands before the year is out.
Stephen Hawking may be a distinguished professor of mathematics, but he just schooled Piers Morgan on gender equality.
During an interview with the legendary British scientist on Monday, Morgan posited that the U.K.s roster of high-profile women in politics points to scientific evidence of gender equality.
But Hawkings response suggested the controversial TV host was overlooking a more important factor in the fight for womens empowerment.
It is not scientific proof of gender equality that is required, but general acceptance that women are at least the equals of men or better, Hawking told Morgan on Good Morning Britain.
If we factor in high-power women in Europe as well, such as [German Chancellor] Angela Merkel, it seems we are witnessing a seismic shift for women to accede to high-level positions in politics and society, he added. I welcome these signs of womens liberation. But there may still be a gap between those women achieving high public status and those in the private sector.
Morgan has faced harsh criticism in recent months for his vitriolic comments about women.He frequently engages in Twitter tirades against what he calls the feminazis and the creeping global emasculation of [his] gender. In January, he railed against the historic Womens March on Washington, deeming the event absurd and attacking its participants as rabid feminists.
Hawking offered a stark contrast to the controversial TV hosts views. When Morgan asked Hawking if he is a feminist, his response was resolute.
Yes, Hawking said. I have always supported womens rights.
I moved the admission of women to my college, Gonville and Caius College, Cambridge, he added. The results were wholly good.
Watch the full interview below:
In California, radical scientists and billionaire backers think the technology to extend life by uploading minds to exist separately from the body is only a few years away
Heres what happens. You are lying on an operating table, fully conscious, but rendered otherwise insensible, otherwise incapable of movement. A humanoid machine appears at your side, bowing to its task with ceremonial formality. With a brisk sequence of motions, the machine removes a large panel of bone from the rear of your cranium, before carefully laying its fingers, fine and delicate as a spiders legs, on the viscid surface of your brain. You may be experiencing some misgivings about the procedure at this point. Put them aside, if you can.
Youre in pretty deep with this thing; theres no backing out now. With their high-resolution microscopic receptors, the machine fingers scan the chemical structure of your brain, transferring the data to a powerful computer on the other side of the operating table. They are sinking further into your cerebral matter now, these fingers, scanning deeper and deeper layers of neurons, building a three-dimensional map of their endlessly complex interrelations, all the while creating code to model this activity in the computers hardware. As thework proceeds, another mechanical appendage less delicate, less careful removes the scanned material to a biological waste container for later disposal. This is material you will no longer be needing.
At some point, you become aware that you are no longer present in your body. You observe with sadness, or horror, or detached curiosity the diminishing spasms of that body on the operating table, the last useless convulsions of a discontinued meat.
The animal life is over now. The machine life has begun.
This, more or less, is the scenario outlined by Hans Moravec, a professor of cognitive robotics at Carnegie Mellon, in his 1988 book Mind Children: The Future of Robot and Human Intelligence. It is Moravecs conviction that the future of the human species will involve a mass-scale desertion of our biological bodies, effected by procedures of this kind. Its a belief shared by many transhumanists, a movement whose aim is to improve our bodies and minds to the point where we become something other and better than the animals we are. Ray Kurzweil, for one, is a prominent advocate of the idea of mind-uploading. An emulation of the human brain running on an electronic system, he writes in The Singularity Is Near, would run much faster than our biological brains. Although human brains benefit from massive parallelism (on the order of 100 trillion interneuronal connections, all potentially operating simultaneously), the rest time of the connections is extremely slow compared to contemporary electronics. The technologies required for such an emulation sufficiently powerful and capacious computers and sufficiently advanced brainscanning techniques will be available, he announces, by the early 2030s.
And this, obviously, is no small claim. We are talking about not just radically extended life spans, but also radically expanded cognitive abilities. We are talking about endless copies and iterations of the self. Having undergone a procedure like this, you would exist to the extent you could meaningfully be said to exist at all as an entity of unbounded possibilities.
I was introduced to Randal Koene at a Bay Area transhumanist conference. He wasnt speaking at the conference, but had come along out of personal interest. A cheerfully reserved man in his early 40s, he spoke in the punctilious staccato of a non-native English speaker who had long mastered the language. As we parted, he handed me his business card and much later that evening Iremoved it from my wallet and had a proper look at it. The card was illustrated with a picture of a laptop, on whose screen was displayed a stylised image of a brain. Underneath was printed what seemed to me an attractively mysterious message: Carboncopies: Realistic Routes to Substrate Independent Minds. Randal A Koene, founder.
I took out my laptop and went to the website of Carboncopies, which I learned was a nonprofit organisation with a goal of advancing the reverse engineering of neural tissue and complete brains, Whole Brain Emulation and development of neuroprostheses that reproduce functions of mind, creating what we call Substrate Independent Minds. This latter term, I read, was the objective to be able to sustain person-specific functions of mind and experience in many different operational substrates besides the biological brain. And this, I further learned, was a process analogous to that by which platform independent code can be compiled and run on many different computing platforms.
It seemed that I had met, without realising it, a person who was actively working toward the kind of brain-uploading scenario that Kurzweil had outlined in The Singularity Is Near. And this was a person I needed to get to know.
Researchers at Strathclyde university are working to combat a deadly tropical disease – using mathematics.
Dengue fever is caused by a virus carried by Aedes mosquitoes.
The number of cases has grown dramatically in recent years with close to 60 million people catching it every year.
Although it is fatal in only a small proportion of cases, it means deaths are still in the tens of thousands.
The World Health Organisation says 500,000 people a year need hospital treatment for dengue in Africa, the Americas, the eastern Mediterranean, southeast Asia and the western Pacific.
The currently favoured approach is to search and destroy the mosquitoes using methods such as spraying fogs of insecticides.
But the authorities in Malaysia wanted something more environmentally friendly which did not increase the mosquitoes’ resistance and kill their predators.
Which is why the Strathclyde University team, led by mathematician Dr David Greenhalgh, has been working with its Malaysian partners to assess the effectiveness of a new type of mosquito trap.
The exact design is still under wraps but I can reveal that it looks a bit like a yogurt pot.
That belies its huge potential in a new approach to fighting tropical diseases: don’t use search and destroy – outsmart the insects.
“The trap contains a chemical solution that attracts female mosquitoes into it,” Dr Greenhalgh says.
“There’s a piece of paper leading into the chemical solution.
“The female mosquitoes that are attracted to the trap lay their eggs on the piece of paper and the chemical stops the eggs developing.”
Mathematics comes into the process because Dr Greenhalgh and colleagues have built a computer model of how the disease spreads.
From that they can simulate how the trap affects the spread of the virus among people and mosquitoes.
He says people go through different stages of the disease.
“There are four different types of dengue, four different serotypes,” he says.
“Usually the infection with the first serotype is quite mild.
“But if you get a second infection with a different strain it can have very serious effects.”
Dr Greenhalgh adds: “As well as modelling how the people go through those different stages, the mosquitoes also go through different stages.
“So you’re trying to model how these populations interact, with mosquitoes biting people, with the disease spreading from people to mosquitoes and vice versa.”
The variables in the mathematical model include the number of traps, the area’s history of dengue infections, plus the numbers of mosquitoes and breeding sites.
So far the indications are that both the simulation and the real life traps are working well.
In a small-scale test in three blocks of flats in Kuala Lumpur the number of dengue cases was reduced from 53 in 2013 to 13 the following year.
In 2015, after the trial was over, the number of infections rose again to 57.
Dr Greenhalgh warns that these are small numbers but also promising ones.
Further research is now examining the effectiveness of the trap in different conditions.
The collaboration is between Strathclyde, Malaysia’s Institute for Medical Research and the Kuala Lumpur-based business One Team Network Solutions, which designs low-tech pest control devices.
The UK delivery partner is the British Council Malaysia. The project is being funded by the UK government’s Newton Fund and the Malaysian government’s High Impact Programme 2.
If the trap and its mathematical model work on a large scale it will have implications for health on a global scale.
A British teenager has contacted scientists at Nasa to point out an error in a set of their own data.
A-level student Miles Soloman found that radiation sensors on the International Space Station (ISS) were recording false data.
The 17-year-old from Tapton school in Sheffield said it was “pretty cool” to email the space agency.
The correction was said to be “appreciated” by Nasa, which invited him to help analyse the problem.
“What we got given was a lot of spreadsheets, which is a lot more interesting than it sounds,” Miles told BBC Radio 4’s World at One programme.
The research was part of the TimPix project from the Institute for Research in Schools (IRIS), which gives students across the UK the chance to work on data from the space station, looking for anomalies and patterns that might lead to further discoveries.
During UK astronaut Tim Peake’s stay on the station, detectors began recording the radiation levels on the ISS.
“I went straight to the bottom of the list and I went for the lowest bits of energy there were,” Miles explained.
Miles’s teacher and head of physics, James O’Neill, said: “We were all discussing the data but he just suddenly perked up in one of the sessions and went ‘why does it say there’s -1 energy here?'”
What Miles had noticed was that when nothing hit the detector, a negative reading was being recorded.
But you cannot get negative energy. So Miles and Mr O’Neill contacted Nasa.
“It’s pretty cool”, Miles said. “You can tell your friends, I just emailed Nasa and they’re looking at the graphs that I’ve made.”
It turned out that Miles had noticed something no-one else had – including the Nasa experts.
Nasa said it was aware of the error, but believed it was only happening once or twice a year.
Miles had found it was actually happening multiple times a day.
Prof Larry Pinksy, from the University of Houston, told Radio 4: “My colleagues at Nasa thought they had cleaned that up.
“This underscores – I think – one of the values of the IRIS projects in all fields with big data. I’m sure there are interesting things the students can find that professionals don’t have time to do.”
The professor – who works with Nasa on radiation monitors – said the correction was “appreciated more so than it being embarrassing”.
“They obviously think I’m a nerd,” the sixth-former said. “It’s really a mixture of jealousy and boredom when I tell them all the details.”
He added: “I’m not trying to prove Nasa wrong. I want to work with them and learn from them.”
The director of IRIS, Prof Becky Parker, said this sort of “expansion of real science in the classroom” could attract more young people to STEM subjects (science, technology, engineering, mathematics).
She added: “IRIS brings real scientific research into the hands of students no matter their background or the context of the school. The experience inspires them to become the next generation of scientists.”

Learning to survive in a world dominated by the internet should be as important for children as reading and writing, says a House of Lords report.
Lessons about online responsibilities, risks and acceptable behaviour should be mandatory in all UK schools, the Lords Communications Committee argues.
The internet is “hugely beneficial” but children need awareness of its hazards, said committee chairman Lord Best.
Industry leaders said education was key to keeping children safe online.
The Lords report builds on findings by the Children’s Commissioner for England in January that the internet is not designed for children, despite them being the biggest users by age group.
“Children inhabit a world in which every aspect of their lives is mediated through technology: from health to education, from socialising to entertainment.
“Yet the recognition that children have different needs to those of adults has not yet been fully accepted in the online world,” say the Lords.
Lord Best added: “There is a lot of material which makes the internet harmful but it can also be hugely beneficial – a way for children to interact and find out about the world.”
However, they need to cope with online pornography, internet grooming, sexting and body image issues, he said, as well as building resilience to the addictive properties of internet games which are “designed and developed to keep users online, missing out on sleep as they stay in their bedrooms glued to the screen”.
Children also need to be aware of the dangers of fake news and covert advertising online, he added.
The report argues that “digital literacy should be the fourth pillar of a child’s education alongside reading, writing and mathematics and be resourced and taught accordingly”.
It should form the core of a new curriculum for personal social health and economic education, it adds.
It backs the government’s move to make sex and relationships education statutory in England but says PSHE should also be mandatory in all schools, with the subject included in inspections.
The report notes “a worrying rise in unhappy and anxious children emerging alongside the upward trend of childhood internet use” and calls for more robust research into a “possible causal relationship” alongside immediate action to prevent children being affected.
Overall, the report says the internet should “do more to promote children’s best interests” but found self regulation by industry was “failing” and that commercial interests “very often” took priority.
Meanwhile, it adds, government responsibility is “fragmented” with little co-ordinated policy and joined-up action.
Other recommendations include:
“This issue is of such critical importance for our children that the government, civil society and all those in the internet value chain must work together to improve the opportunities and support where the end user is a child,” the Lords conclude.
The Internet Services Providers Association rejected calls for stronger regulation, while backing the report’s call for better education.
James Blessing, who chairs the ISPA, said that the UK was regarded as a world leader in keeping children safe online “through a self-regulatory approach”.
“We believe the most effective response is a joint approach based on education, raising awareness and technical tools,” he said.
The government said it wanted to make the UK the safest place in the world for young people to go online.
“Ministers have begun work on a new internet safety strategy that will help make this a reality, and we will carefully consider the recommendations included in the Lords Communications Committee Report as part of this process,” said a spokesman.
