Young Scientist winners use a new method to solve an old maths problem

Two Dublin students were awarded the top prize at a virtual awards ceremony for their project focused on Euclidean geometry.

Aditya Joshi and Aditya Kumar, both 15 years old, have been named the overall winners of the 2022 BT Young Scientist and Technology Exhibition (BTYSTE).

The third-year students from Synge Street in Dublin won with their project entitled ‘A New Method of Solving the Bernoulli Quadrisection Problem’.

The Bernoulli quadrisection problem is an old, difficult problem in Euclidean geometry. The students devised a new method to solve it using an algorithm that was inspired by natural phenomena such as the flocking of birds.

Joshi and Kumar have been awarded a €7,500 prize and will go on to represent Ireland with their project at the EU Contest for Young Scientists later this year.

“I’m very speechless and happy,” Kumar said when their project was announced as the winner.

Joshi said the idea was inspired by a project his brother did for BTYSTE in 2018. As well as being part of the winning team, Joshi turned 15 today (14 January).

Speaking to SiliconRepublic.com, the boys said it felt surreal to win the young scientist competition. “It felt like a dream,” said Kumar.

Explaining their project, Joshi said they took an old problem and used the modern technique of particle swarm optimisation to solve it. “It worked out really well. So then we were able to use that method and then solve lots of other problems with it.”

Joshi also said the problem has a practical real-world application in the design of electronics.

Kumar said in the future he either wants to go down the route of becoming a software engineer or a doctor, while Joshi has ambitions of going into robotics. “Also, I kind of want to start a business but I have no ideas as of yet,” said Joshi.

‘A testament to the tenacity of the students’

Now in its 58th year, BTYSTE launched on Wednesday with more than 1,000 students representing 219 schools from 29 counties competing.

A total of 550 projects were chosen from 1,440 entries and climate, health and new technologies featured heavily among the projects.

The award for best individual young scientist went to Ross O’Boyle from Portmarnock Community School for his project investigating the effectiveness of various ventilation methods using CO2 as a proxy for the spread of Covid-19 in both controlled and real-life scenarios.

The runner-up individual prize went to St Aidan’s CBS student Andrei Florian for his project focusing on electoral voting systems using blockchain, while the runner-up group comprised Dara Newsome and David Hughes from Mercy Secondary School in Kerry for a wearable smart device for dementia patients.

Other Young Scientist award winners included Taha Fareed and Jevin Joy, two 15-year-old students from Coláiste Phadraig in Lucan, who created a website with an AI model that uses deep learning to predict the value of cryptocurrencies with high precision. They came joint second in the intermediate technology group category and bagged a special award from Science Foundation Ireland.

Additionally, the Tom Burke bursary worth €1,000 went to Robert Troy from CBS Charleville for his project Smart Yard, which looked at IoT monitoring of farm metrics to reduce emissions.

Ahead of the winner’s announcement, BT Ireland boss Shay Walsh thanked the students and said the judges were blown away by the projects, particularly with the extra challenges brought on by the Covid-19 pandemic.

“You are a generation that is actively seeking solutions some of the biggest challenges that humanity faces,” he said. “Please keep your passion for STEM and the possibilities that come with it.”

Minister for Education Norma Foley, TD, added that it was heartening to see the level of creativity in this year’s projects. “The calibre of entries are a testament to the tenacity of the students behind them.”

Chemistry Problems & Quantum Computing

The researchers compared the results of a conventional and quantum computer to minimise error calculations, which could eventually be scaled up to solve more complicated problems.

Scientists in Sweden have successfully managed to use a quantum computer to solve simple chemistry problems, as a proof-of-concept for more advanced calculations.

Currently, conventional supercomputers are used in quantum chemistry to help scientists learn more about chemical reactions, which materials can be developed and the characteristics they have.

But these conventional computers have a limit to the calculations they can handle. It is believed quantum computers will eventually be able to handle extremely complicated simulations, which could lead to new pharmaceutical discoveries or the creation of new materials.

However, these quantum machines are so sensitive that their calculations suffer from errors. Imperfect control signals, interference from the environment and unwanted interactions between quantum bits – qubits – can lead to “noise” that disrupts calculations.

The risk of errors grows as more qubits are added to a quantum computer, which complicates attempts to create more powerful machines or solve more complicated problems.

Comparing conventional and quantum results

In the new study by Chalmers University, scientists aimed to resolve this noise issue through a method called reference-state error mitigation.

This method involves finding a “reference state” by describing and solving the same problem on both a conventional and a quantum computer.

The reference state is a simpler description of a molecule that can be solved by a normal computer. By comparing the results from both computers, the scientists were able to estimate the scale of error the quantum computer had in its calculation.

The difference between the two computers’ results for the simpler reference problem was then applied to correct the quantum computer’s solution for the original, more complex problem.

This method allowed the scientists to calculate the intrinsic energy of small example molecules such as hydrogen on the university’s quantum computer.

Associate professor Martin Rahm – who led the study – believes the result is an important step forward that can be used to improve future quantum-chemical calculations.

“We see good possibilities for further development of the method to allow calculations of larger and more complex molecules, when the next generation of quantum computers are ready,” Rahm said.

Research is happening around the world to fix the problems limiting the development of more advanced quantum computers.

Earlier this month, Tyndall’s Prof Peter O’Brien told about his group’s work in addressing a key challenge in quantum technology and how quantum communications will make eavesdropping ‘impossible’.

How News Helicopters Ushered A Fresh Television Genre In Los Angeles

By Darren Wilson

Fifteen minutes of fame was not enough for Johnny Anchondo. Local television devoted some 100 minutes of live coverage to this repeat offender, following one of the wildest chases Los Angeles has seen in recent years. In that time, the 33-year-old criminal ran a stop sign and caused an immense mobilization of the police as he stole two pickup trucks, rammed into dozens of vehicles at high speed and escaped from at least 15 patrol cars that were hot on his trail for some 12 miles. All of this was recorded by the all-seeing eye in the sky, news helicopters.

“Chases are the best. They are dynamic, they move fast. Things can change in an instant. Sometimes they seem endless from up there,” says Stu Mundel, one of the journalists who have been following events on the city streets from a helicopter for decades. “And I say this from the bottom of my heart, it’s genuine, but I always wish things would end well,” he adds.

In Los Angeles, chases are now a television genre in their own right. Journalists like Mundel fly for hours over a gigantic urban sprawl of 88 cities with 11 million people. From way up high, they report on traffic, crashes, shootings and fires in the metropolitan area. But few events arouse the audience’s interest as much as the chases through the city’s vast thoroughfares. The police chase starring Anchondo attests to that fact; the video has over 28 million views on YouTube.

The genre was born in this city. The idea came to John Silva, an engineer for a local television station, while he was driving his car on a freeway near Hollywood. “How can we beat the competition?” he wondered. The answer came to him behind the wheel. “If we could build a mobile news unit in a helicopter, we could beat them in arriving to the scene, avoiding traffic and getting all the stories before the competition,” Silva told the Television Academy in a 2002 interview.

In July 1958, a Bell 47G-2 helicopter made the first test trip for the KTLA network, becoming the first of its kind anywhere in the world. By September of that year, Silva’s creation, known as the Telecopter, already had a special segment on the channel’s news program. Before long, every major television network had one. Silva died in 2012, but his invention transformed television forever.

The chase genre’s crowning moment came in June 1994, when the Los Angeles police chase of a white Ford Bronco was broadcast live on television. In the back of the vehicle was O.J. Simpson, the former football star, whom the authorities had named the prime suspect in the murder of his ex-wife and her friend. Bob Tur (now known as Zoey Tur after a sex change operation), the pilot of a CBS helicopter, located the van on the 405 freeway being followed by dozens of patrol cars. Within minutes, there were so many helicopters following the convoy that Tur found the scene worthy of Apocalypse Now. The audience was such that TV stations interrupted the broadcast of Game 5 of the NBA Finals to follow the chase, which lasted two hours.

Motorists wave to ex-football star O.J. Simpson as he flees from the police in the back of a white Ford Bronco pickup truck driven by Al Cowlings in Los Angeles, California, in June 1994.

“It’s a very interesting thing. It may sound morbid, but it’s not. People follow [police chases] because they are like a movie, we want to know how it will end and how the story unfolds: will good triumph over evil? Or will this person manage to escape? We journalists are objective, but the adrenaline and excitement is genuine,” says Mundel. In his years of experience, he has seen how technology has evolved. In the 1990s, people used a paper map as a guide. Today, viewers can see a map superimposed on the images Mundel captures with his camera.

Four out of 10 chases are initiated after a vehicle is stolen. The second most common reason for them are hit-and-runs by drivers who are drunk or under the influence of drugs. According to the Los Angeles Police Department, most fugitives are hiding a more serious crime: homicide, rape or violent robbery. In 1998, only four out of the 350-plus drivers arrested after a chase were let off with only a traffic ticket; five hundred chases were recorded that year.

A growing phenomenon

In 2022, 971 chases were recorded. On average, chases last about 5.34 minutes and cover about five miles, although the vast majority (72%) end within five minutes and do not travel more than two miles. 35% of documented chases ended in crashes with injuries or fatalities in 2022. That figure represents a slight decrease from 990 in 2021. In 2019, there were fewer: 651 chases and 260 crashes.

A few decades ago, authorities tried to reassure Angelenos by claiming that a person had a one in four million chance of accidentally being killed in a police chase of a criminal. “There’s a better chance of being struck by lightning,” the police department estimated. But things have changed. An official report presented in April indicates that, over the past five years, 25% of chases have left people dead or injured. That almost always includes the suspect, but the number of innocent people who have been hurt has also increased.

News Helicopters Ushered A Fresh Television Genre In Los Angeles

Although there is plenty of material on the street, uncertain times for local journalism have limited coverage. Univision and Telemundo have dispensed with their helicopters in Los Angeles. Fox and CBS have joined forces and are using one aircraft instead of two. For the time being, KTLA, which invented the genre, remains committed to having a helicopter in the air.

The days may be numbered for these televised events. Some metro police departments have asked their officers to stop chasing criminals at high speed for the safety of the public. Instead, they have employed technology with high-definition cameras and drones to chase criminals, as has happened in cities like Dallas, Philadelphia and Phoenix.

The Los Angeles police have said that they are studying the implementation of the Star Chase system in some of their vehicles. Star Chase features a launcher that triggers a GPS transmitter, tagging a fleeing vehicle and allowing the authorities to track the position of the person who has escaped in real time. Another measure under consideration is the use of an industrial-strength nylon net that traps the rear axle of the fleeing car. All of this could yield dramatic footage for the eye in the sky.
