Pathfinders: The Golden Age of Arabic Science

Book Review

This book was published in 2010 but unfortunately remains one of the few examples of positivity towards Islam coming from the West. British Jim Al-Khalili was born in Iran and he wrote about science during the early days of Islam, also giving a beautiful picture of life before the Islamic revolution of 1979 that forced his family to flee. Al-Khalili is a an accomplished theoretical physicist and broadcast presenter for BBC Horizon, The Big Bang, Tomorrow’s World and Science and Islam (the parallel TV series to this book).

If you love history, you will love this book as Al-Khalili goes into great depth—three whole chapters—to explain the circumstances that led to the golden age of science within Islam. The standard history of science texts usually paints the Islamic Empire (the scientific golden age was mostly from the 8th till 13th century) as being the great saviour of Greek texts having translated the works of Pythagoras, Aristotle, and other Greek scientists that then instigated the Renaissance in Europe when they were translated into Latin and other languages. Al-Khalili shows that these scholars were not mere translators but innovative in Mathematics, Astronomy, Medicine, Chemistry, and other fields. Scholars came from all major faiths.

Al-Khalili takes till Chapter Four to start detailing these scientific achievements. I would have preferred if these came sooner. He reveals facts such as that the zero was not invented by the Arabs but by the Indians, the Arabs simply used it to powerful effect. The Arabs pushed mathematics by leaps and bounds and Al-Khalili uses multiple chapters to outline them all. They invented decimal fractions, part-invented the decimal system, and invented proofs of mathematical equations through induction, using pages of equations to break down the initial equation and prove it absolutely, which is still the gold standard for modern mathematicians.

“He reveals facts such as that the zero was not invented by the Arabs but by the Indians, the Arabs simply used it to powerful effect”

He talks about the polymath al-Razi (854 AD–925 AD). Al-Razi lays claim to classifying substances according to their properties based on experimentation. He used experimentation to select the most hygienic site for Baghdad’s hospital, improved medical ethics and even accepted mentally ill patients (when concurrently the Christian world saw them as devil-possessed), distinguished between curable and incurable disease, clinical trials, and many other advances. His medical textbook al-Kitab al-Hawi fills 23 modern volumes, the largest in the Arab world.

Al-Khalili talks about plenty of other advances and scholars that are sure to surprise readers. The book can be slightly challenging for people to get through. Al-Khalili writes beautifully, clearly, but somewhat academically. If you’re interested in learning about a neglected part of the history of science, this book is for you.

I spoke to Al-Khalili back in 2010 about the TV series related to this book. His final words were that I had to bring his series to Malta. Words relevant then as they are now: a shining light on the possible positivity within Islam interpreted in the right way.

Think ICT in Health Care

Ivan Bartolo
Ivan Bartolo

I have been directly involved in ICT for over 30 years. The last 10 years have been all dedicated to ICT in health.

I have visited hospitals and health centres in the United States, Canada, the United Kingdom, Ireland and Italy. During the several health conferences I have attended, I met with people from practically every corner of the world. Their common denominator: no health system is sustainable unless ICT is perceived as an enabler to assist health providers deliver an improved and more efficient care service that governments can afford.”Malta shares this concern. The added pressure is its ageing population.

Q:How can ICT truly reduce the financial pressures on our Health Service and make it sustainable?

A:Malta needs to develop a culture where citizens realise their responsibility to monitor their own health and maintain their own online electronic medical record. This can be done through daily, weekly or monthly monitoring of vital signs such as blood pressure, weight and others. Studies prove that people using eMonitoring services take better care of their own health.

I urge the Ministry of Health to run a simple pilot project in Malta. It could be run amongst the diabetic community. The pilot project would include 1,000 people. 500 of them will use the standard glucose-monitoring device while the other 500 will use a personal, electronic glucose-monitoring device. Within three to six months the results will show the superiority of eMonitoring devices for patient care. These existing health tools can enable people to live healthier lives and stay away from our overburdened hospital. The key is to control a condition without depending on medicines.

Q:Length of stay in hospitals and outpatient visits can be reduced through eMonitoring devices. How?

A:How many patients remain in hospital after medical intervention to have their vital signs monitored? Using these devices patients can be discharged from Mater Dei sooner by being given an eMonitoring kit to monitor themselves from home. The data would be sent electronically to Mater Dei for doctors or clinicians to analyse. These devices could reduce the patient length of stay and make more beds available at Mater Dei translating into reduced costs and waiting lists. They could alleviate the number of outpatient visits that would reduce pressure on the infrastructure and workforce providing more time to increase care quality. Such devices provide an opportunity for every Maltese citizen to have an online electronic medical record that would be always available to clinicians and general practitioners.

My vision for the Maltese health service is one of empowerment. The patient will be enabled to take better care of him or herself and become more accountable, disciplined, and committed to self-healthcare in the same way someone is committed to their job or hobby.

Social Wellbeing Policy at University?

University can be incredibly stressful. Staff perform high level work with plenty of academic responsibilities, while balancing a private life and leisure time. The number of students at University is rising every year. For academic and support staff this means a more intensive workload, pressure, and stress. For students it is the pressure of attaining good results, maintaining relationships, and other social and emotional wellbeing issues, such as coping with peer pressure, struggling with deadlines, and worries about the future. Numerous studies suggest that examinations negatively impact on student health and wellbeing. Some coping strategies and time management programmes have evolved at the University of Malta, for example by the University Chaplaincy. Such well-meaning initiatives are good and do good, but tend to happen sporadically and around examination time.

Many University of Malta students balance multiple identities. They often fall outside the typical demographic of an 18-year-old sixth form school leaver. Our students come from diverse socio-economic backgrounds, and may be studying full-time or part-time, with a variety of life roles: mature students, women with care responsibilities, persons challenged by disability or facing problems due to sexual orientation. Whatever the situation in life, each diverse identity places increased demands upon the students’ time and private life. These demands influence their University experiences, study perceptions, and learning style. Their peers might treat them differently due to their background. 

“A social wellbeing policy will help foster confidence in its approach to academic learning, and to eliminate discrimination in favour of a more inclusive learning environment”

Besides worries about assignment deadlines and writing exams, many students are also in employment. I am not sure this trend is in line with University of Malta regulations, nevertheless, that is the situation. Students also worry about future prospects with no guarantee of secure employment after finishing their studies. So it is not only academic concerns that come in the way of student social wellbeing, and these may lead to high levels of stress, anxiety or frustration, depressed mood, difficulties with time management, procrastination, poor concentration, withdrawal from friends or family, or physical symptoms such as headaches, sleep problems, and exhaustion. University life presents numerous stress factors that may trigger off mental health difficulties.

Students experiencing stress are normally recommended psychological intervention and counselling, which may be beneficial for extremely stressed students. However, research suggests that physical activity helps improve mental health and wellbeing. The University of Malta, through its Work Resources Fund, promotes cycling through the Green Travel Plan. The initiative is more about sustainability and the environment, apart from a solution to the parking problem. However, cycling does improve our mental health and wellbeing, and is a free personal de-stressor by taking our mind off work or study, and leads to healthier lifestyle choices. stressed-student

A social wellbeing policy for University will help foster confidence in its approach to academic learning, and to eliminate discrimination in favour of a more inclusive learning environment. Indeed, the principles of equality and diversity such as gender or disability are essential for a true understanding of social wellbeing, and these same principles need to be included in our University’s policy document and implemented in practice. Diversity in a dynamic, intellectual environment enriches professional and educational experiences for both staff and students.

Diversity on campus is needed and important for a healthy University. Internationally, social wellbeing on campus is being promoted through an organisational structure embedded into the ethos, culture, policies, and daily practices of a university. A social wellbeing policy includes an improved occupational health and safety system, and a commitment to address mental wellbeing, physical inactivity, unhealthy eating and substance misuse. The University needs constant commitment to positively influence the life and work of all staff and students.

The University is encouraged to guard the integrity of its communication system. Collaboration and open communication fosters conversations and relationships necessary to bring about social wellbeing. The communication process needs to be trusted and confidential for team spirit and social wellbeing. For instance, I would strongly argue for an email policy that discourages unnecessary use of bcc in emails, as the practice of not telling the original addressee is unethical and downright deceitful. 

The University of Malta could establish itself as a national contact point on the European Network for Health Promoting Universities (see www.eurohpu.aau.dk). It would commit the University to place social wellbeing high on its policy agenda. A working document published by the World Health Organisation Regional Office for Europe provides guidance on how to set up and develop a health-promoting university project, which would enhance and protect the social wellbeing of all staff and students.

Finally, I would also suggest an exploratory research study about aspects of university life, stress factors in teaching and learning activities, and how these impact on individual experiences. The aim is to understand the general quality of life, and how this can be improved for an informed social wellbeing policy document at the University of Malta.

Science and Politics

DavidMagri

Think meets up with Dr David Magri to tell us more about how he is trying to help scientists and politicians to network. Evidence-based policies need the input of scientists from all fields and are the future for Malta’s policy makers to develop a better, richer, and happier Malta.

Q: In a small country like Malta were everyone knows each other, why do scientists and politicians need to network? 

A: Even in a small country like Malta, people do not know everybody. In particular, scientists and politicians are two groups of individuals with busy schedules and different priorities. Because of the inherent nature of their professions, these two groups have no natural reason to meet. Scientists spend a considerable amount of time in their office, laboratory, in meetings, out on fieldwork, and at conferences. Politicians spend a substantial amount of time in their office, in the House of Parliament, at meetings, events, and attending conferences. However, for the nation’s interests, science and research policy is important for future competitiveness with regards to technical skills and human resources. Parliamentarians and governments set the national priorities for research, but researchers need to meet these research objectives. Researchers have a better understanding of what is feasible and what resources are needed.

“Scientists and politicians are two groups of individuals with busy schedules and different priorities”

Q:How are you trying to get them to engage?

A: The Malta Chamber of Scientists has established Science in the House as a networking forum between scientists and parliamentarians. Under the auspices of the House of Representatives, Science in the House is also a poster exhibition highlighting some of the leading research conducted in Malta, particularly at the University of Malta. Now in its third year, the event continues to build momentum with greater participation every year. It takes place in the Presidential Palace in Valletta. This year a number of parliamentarians with science-related interests and backgrounds have been asked by personal invitation to attend the opening ceremonies of Science in the House.

Q:What is the role of Science in the House as part of Science in the City – European Researcher’s Night?

A: Science in the House is the opening ceremony for the Science in the City festival. During the weekend festival the Presidential Palace is open to the public in the evening. The poster exhibition is left on display for parliamentarians to view, and afterwards left on display over the Notte Bianca festival allowing the general public including students, parents, and tourists to view the exhibition. During the week an estimated 6,000 visitors viewed the exhibition last year.

Love Letter

BoardGame-Review

The Microgame is a buzzword that has exploded over the last year in the board game community. Microgames are video game mini-games but analog and a lot more awesome. Love Letter is the microgame that popularised the format—Kanai’s 16-card wonder. 

Love Letter was not the first microgame, it wasn’t even Kanai’s first microgame. R, another game of his was a popular title which you could buy by emailing the designer. He would then mail you an envelope with the cards in it, which was the board game itself. Love Letter is a spiritual successor to ‘R’, and the first of his works to have an international distribution.

In Love Letter you are trying to deliver the proverbial letter to the princess. You do this by gaining the favour of her closest friends. The deck is made up of these people, all having a number. The person who holds the card with the highest number at the end of the round, or the last person standing, wins. 

In the game you always keep one card in your hand, and at each turn you draw a card and choose one of the two to discard. Each card though, has a specific ability, which activates as soon as you discard it. For example, if you play a Guard, you have the opportunity to try to guess another player’s card. If you do, that player is out. The Countess for example, cannot be caught with the Prince or the King (you must discard her if she does). This would mean fornication. The Priest can see another player’s card, since this constitutes confession, and the Baron can kick out anyone of a lesser number than him due to politics.

The game takes a little bit of getting used to. It is quite different from other mainstream games but I have not had so much fun with cards since I first found money in birthday cards.

With almost infinite replayability, a price point of around €9, extreme portability, and tight, nail biting moments, Love Letter is a definite buy. There is very little chance of going wrong. Five Stars.

An Automatically Tailored Experience

Digital games need to keep players engaged. Since games are interactive media, achieving this goal means that game designers need to anticipate player actions to create a pre-designed experience. Traditionally, developers have achieved this by restricting player freedom to a strict set of actions thereby curating player experience and ensuring the fun factor. However, games are taking a different route with more users making their own content (User Generated Content, UGC) through extensive creativity tools which make it hard to predict player experience.

Vincent E. Farrugia
Vincent E. Farrugia

To overcome these challenges Vincent E. Farrugia (supervised by Prof. Georgios N. Yannakakis), merged game design and artificial intelligence (AI). He developed a software framework for handling player engagement in environments which feature user generated content and groups. The three pronged solution tackles problems during game production, playing the game itself, and making sure the framework is sustainable. To maintain engagement within groups he analysed data for a particular person within the group but also patterns common across the whole group. Farrugia created software tools, autonomous AI aids, and tools to test and support the framework.

The software framework is made up of inter-operating modules. Firstly, an engagement policy module allows designers to specify theories to express their vision of positive game engagement. Player modelling then shapes this backbone to specific player engagement needs. The module can autonomously learn from player creations as reactions to game stimuli. Individual and group manager modules use this mixture of expert knowledge, AI learnt data, and player game-play history to automatically adapt game content to solve player engagement problems. This procedural content generation (PCG) is tailored for a specific player and time.

The framework’s abilities were showcased in a digital game also developed by Farrugia. Various technologies were incorporated to encourage player creativity in group sessions and to enhance networking. The setup also allowed the AI to quickly learn from each player via parallelism. Initial testing used a simulated environment with software agents. Preliminary testing on real players followed. The simulation was through a personality system to validate the underlying algorithms under various conditions. The resulting diverse game-play styles provide suggestions for AI model improvement. Farrugia is enthusiastic about future work for this AI framework and giving developers better tools to allow player creativity to flourish while maintaining positive game-play experiences.

Smaller, Faster, and just as pretty

Video streaming uses a lot of  bandwidth. Internet service providers can either limit bandwidth or provide more. To bypass this problem newer encoders aim to compact video into smaller packages, to keep the same video quality but a smaller size. 

The problem is the variety of video devices available that range from mobiles, tablets, and high definition TVs. This diversity results in various different video transmissions being needed. To avoid encoding the same sequence several times and reduce the traffic over a network, video coding called H.264/Scalable Video Coding (SVC) was introduced. This type of video coding allows a single stream to encode for time, space, and quality. This technology saves bandwidth. SVC is expected to become the standard for Internet streaming. The only thing holding it back is the need for a complex encoder.

Kurt Abela

Kurt Abela (supervised by Dr Ing. Reuben Farrugia) proposed the use of a Graphics Processing Unit (GPU) based encoder to speed up the encoder. The Block Motion Estimation (BME) module within SVC takes up the bulk of the total encoding time in standard H.264/AVC. Abela designed certain modules to be optimised for NVIDIA GPUs. Through an asynchronous programming model, the video encoder could be run simultaneously on the CPU (Computer Processing Unit) and GPU. By using this novel encoder, encoding was sped up at most 436x times, when compared to a reference model, with no loss in quality. The encoder was sped up even more with further improvements to allow real-time HD video encoding. 

This system is much cheaper and easier to use than leading alternatives. GPUs are very cheap and already found in most computers. Further developments on GPUs could soon see them replace more expensive encoders in datacentres.
