Co-inventor of DLS method, dies

Published

on

Frank Duckworth, the man whose mathematical knowledge helped to revolutionise rain-affected cricket, has died aged 84.

The Lytham-born statistician created the Duckworth-Lewis method, a model to recalculate scores when limited-over matches were curtailed by weather conditions, with fellow Lancastrian Tony Lewis.

Announcing Duckworth’s death, fellow statistician Rob Eastaway said he had been “a very genial man” who was “proud” of the method, despite it leaving casual fans somewhat flummoxed.

“A lot of people either claim they don’t understand it or don’t like it, but they know deep down, it is the best way of working,” he said.

The former King Edward VII School Lytham student and University of Liverpool graduate spent his entire career working in the nuclear industry.

Originally employed as a metallurgist, he found he had an ability to extract useful information from masses of numerical measurements.

A course in statistics followed and he later became a statistician, being elected as a fellow of the Royal Statistical Society in 1974.

The formula has become a part of cricket folklore

At the society’s conference in 1992, he presented a short paper which proposed a formula for target correction in rain interrupted one-day cricket matches.

This led him to meet Lewis, a mathematics lecturer, who suggested an analysis of one-day score sheets based on Duckworth’s proposed formula.

Their method was devised in the wake of a farcical Cricket World Cup semi-final between England and South Africa in 1992.

Rain stopped play with South Africa needing 22 runs from 13 balls, but on resumption, the then-method of recalculation, which was based on productive overs, saw them requiring an almost impossible 22 runs off one delivery.

Speaking in 2007, Duckworth, who lived in Gloucestershire, said he recalled hearing BBC Test Match Special commentator Christopher Martin-Jenkins “on the radio, saying ‘surely someone, somewhere, could come up with something better'”.

“I realised that it was a mathematical problem that required a mathematical solution,” he said.

The subsequent Duckworth-Lewis method was first used in the ICC Trophy in Malaysia in 1997 and in 1998, it was applied in New Zealand, South Africa, Pakistan, India and West Indies.

The International Cricket Council adopted the method for the 1999 World Cup in England and it was adopted on a trial basis for all cricket by the ICC in 2001 before becoming the permanent solution three years later.

It is now known as the Duckworth-Lewis-Stern method after Australian statistician Prof Steven Stern became the custodian of the method following his predecessors’ retirement.

Stern updated the method in 2014 to take into account modern scoring trends and T20 cricket.

The method was used as recently as Monday in the rain-affected World Cup match between Afghanistan and Bangladesh.

The Duckworth-Lewis-Stern method was called into action at the T20 World Cup on Monday

Duckworth received an honorary doctorate from the University of Bath in 2015.

In the citation, it said he had been as important to the nuclear industry as he had been to cricket.

“He came to realise the importance of statistics, not just to ensure reactor safety but also to assure the public that the reactors are safe,” it said.

“At that time, there were no statisticians working at the laboratories, so he set about making himself into a statistician.

“Then he had to convince his colleagues and others of the power of statistics, and spreading that idea has been at the core of everything he has done since.

“Persuading the cricket administrators that statistics could help them was just another example of that.”

Mr Eastaway said while the statistician had been a powerhouse when it came to numbers, he also had a lighter side.

“When Tony Lewis died in 2020, he phoned to tell me that people thought he was already dead,” he said.

“They were like a comedy double act.

“Lewis was the straight man and Frank was very jovial.”

China to drift away from SL with Mazagon Dock’s purchase of CDPLC?

Published

By

International relations researcher – Dr. Hasith Kandaudahewa says there is a visible trend of China gradually distancing itself from Sri Lanka since 2023, a process that could accelerate with India’s Mazagon Dock Shipbuilders Ltd. acquiring a majority stake in Colombo Dockyard PLC (CDPLC).

Speaking to the BBC Sinhala Service, Dr. Kandaudahewa has noted that CDPLC’s reputation in global shipbuilding makes the acquisition strategically significant for India, especially when viewed alongside India’s newly opened Vizhinjam International Seaport in Kerala.

This shows that India is steadily strengthening its port infrastructure across the Indo-Pacific and increasing its strategic influence in the Indian Ocean, he has said.

Dr. Kandaudahewa has further pointed out that with China already holding Hambantota Port on a 99-year lease, India’s move to secure the majority stake in CDPLC signals a clear challenge to the Chinese presence in Sri Lanka.

“While China is holding the Hambantota Port on a 99-year lease, India is also trying to show its dominance in Sri Lanka. India is trying to pose a challenge to China by securing a majority stake in the CDPLC. Why, because these two countries are staking their claim to two of the most strategic locations in the same country. Similarly, we are seeing China gradually distancing from Sri Lanka from 2023. The CDPLC seems to be accelerating it even further.”

“In the long term, India is investing in renewable energy programs in Sri Lanka. Even though India may not gain much profit from this, it is trying to further retain Sri Lanka as their closest neighbor.”

The Colombo Stock Exchange has already confirmed that Mazagon Dock Shipbuilders Ltd, a public sector undertaking (PSU) of the Government of India, will acquire a 51% stake in CDPLC currently held by Japan’s Onomichi Dockyard Co. Ltd for USD 52.96 million.

The deal is to be completed in the next 06 months.

Mazagon Dock Shipbuilders Limited, Mumbai, an ISO 9001: 2015 Company is one of the leading shipbuilding yard in India.

Since it was taken over by the Indian government in 1960, Mazagon Dock MDL has built a total 805 vessels including 30 warships, from advanced destroyers to missile boats and 8 submarines.

  • 51%: Onomichi Dockyard Co. Ltd. (Japan) (to be sold to Mazagon Dock)
  • 16.34%: Employees’ Provident Fund (EPF)
  • 5%: Sri Lanka Insurance Corporation – General Fund
  • 4.92%: Sri Lanka Insurance Corporation – Life Fund
  • 3.04%: Sri Lanka Ports Authority
  • 2.42%: Employees’ Trust Fund Board
  • 1.11%: Bank of Ceylon

The Sri Lankan government is moving forward with plans to establish a national network of daycare and therapy centres for children with autism spectrum disorder (ASD) and other neurodevelopmental conditions. 

Secretary to the President Dr. Nandika Sanath Kumanayake has directed officials to prepare a detailed concept proposal within two weeks, following discussions held yesterday (July 09) at the Presidential Secretariat. 

This initiative, championed by President Anura Kumara Disanayake, aims to create a coordinated system involving multiple ministries and government departments, with the Presidential Secretariat overseeing implementation.  
The programme will utilise a Rs 250 million allocation from this year’s budget, channelled through the Ministry of Women and Child Affairs to district-level administrators. Key aspects of the plan include developing specialised human resources, creating a scientifically validated care model and establishing clear operational guidelines. During yesterday’s meeting, officials emphasised the need for an integrated approach that brings together healthcare providers, social services and education specialists to ensure comprehensive support for affected children and their families.  

Senior government figures attending the planning session included Kapila Janaka Bandara, Senior Additional Secretary to the President, K.D.R. Olga Secretary to the Ministry of Women and Child Affairs, Sampath Manthrinayake, Secretary, Ministry of Rural Development, Social Security & Community Infrastructure,  H.A. Hema Perera, Additional Secretary, Darshani Karunaratne, Director, Department of Social Services  and representatives from health, social services and rural development ministries. Medical specialists such as Dr. Varuni Rasadi from the Ministry of Health, Dr. Asiri Hewamalage, Deputy Director (Community Health) and Dr. Santhushitha Senadhipathi from the Lady Ridgeway Hospital also attended the discussions.
