Enjoy your eureka moment

Published

on

Although some of us may not be familiar with the eureka moment, it is a sudden, unexpected flash of insight, inspiration or discovery when you realise a solution to a difficult problem or understand a complex concept. Sometimes the eureka moment is known as an ‘Aha! Moment.’ It is often characterised by a feeling of joy and the immediate clear realisation of truth.

Most of us may have experienced such a moment without knowing what to call it. If you look deep into the concept, you will realise that the eureka moment involves suddenness. Strangely, the insight appears abruptly when your mind is relaxed or not directly focussed on a given problem.

The Greek word ‘eureka’ means ‘I have found it.’ This simple word signifies a triumphant finding or a solution to a problem. The whole concept involves your brain forming unexpected new connections between previously unrelated information. Those who have felt it say the experience is usually accompanied by a rush of adrenalin.

Unusual spectacle

The first reported case of eureka moment comes from ancient Greece. The celebrated Greek mathematician Archimedes of Syracuse was perhaps one of the few people who had experienced a eureka moment. He goes down history as a man who ran naked along a busy street repeating the word ‘Eureka.’ The unusual spectacle stopped the rattle of the carts moving along the busy main street of the Sicilian town. The few women who happened to see a naked man running along the street were horrified. Although some people recognised him, others thought that he was an insane person. All of them had to wait till the following day to find out why he ran naked.

According to Hiero, a noted historian, the king of Syracuse had commissioned a goldsmith to make a crown out of pure gold. However, when the crown was delivered the king had suspicions that the goldsmith had mixed base metal with gold in making the crown. The king ordered the renowned mathematician Archimedes to find out whether the goldsmith had actually used inferior metal in making the crown.

Archimedes was puzzled for a few days not knowing how to find whether only pure gold had been used to make the crown. While thinking of the problem he went to the public bath and stood at the edge of a bathtub. Then he lowered himself into the bathtub. All of a sudden he jumped out of the bathtub and started running shouting loudly ‘Eureka! Eureka!’

Experiments

After returning home Archimedes did a few more experiments and realised that any object completely or partially submerged in a fluid (liquid or gas) experienced an upward buoyant force equal to the weight of the fluid it displaced. This force enabled objects to float if they were less dense than the fluid, as it opposed the downward pull of gravity. Thus, he was able to inform the king how much pure gold was there in the crown.

Archimedes’ father Pheidias was a kinsman of King Hiero. While Archimedes was busy with his inventions, the king commissioned him to make weapons of mass destruction to be used in the event of a war with his rivals. Archimedes wanted only a lever and a place on which to rest it. Eventually, the Roman General Marcellus laid siege on Syracuse. Hiero used the new weapons invented by Archimedes and sank many enemy ships in the sea.

Archimedes was not happy with his deadly weapons. In fact, he despised the mechanical contrivance that made him famous. He thought that his weapons of mass destruction were beneath the dignity of pure science. It may be one reason for him not to leave behind any of his writings. Even in the absence of his writings, historians and the scientific community consider him to be a great mathematician. He was perhaps the only ancient mathematician who had contributed anything of real value to the theory of mechanics.

Strange man

Although he was a great mathematician, we know very little about his personal life. According to historians, he was at times a strange man who could not be fathomed easily. Sometimes he had to be taken to the bath by force. While taking a bath he used to draw geometrical designs on the soap buds on his body! Whenever he solved a mathematical problem, he beamed with happiness like a child.

Although Archimedes’

weapons of destruction were able to keep the invading army at bay, Syracuse fell in 212 BC and he too was killed. Even when Syracuse was overrun by the Roman army, Archimedes might have remained nonchalant. He would have been drawing his geometrical figures quite unmindful of his impending fate. Roman General Marcellus was so aggrieved by the death of Archimedes that he bestowed special favours on the relatives of the slain mathematician. However, the human race will never see another Archimedes. Instead it will see more and more hollow men invading every sphere of human activity.

Silence is not protection: Rethinking sexual education in Sri Lanka

Published

on

Sexual education is a vital component of holistic education, contributing to physical health, emotional well-being, gender equality, and social responsibility. Despite its importance, sexual education remains a sensitive and often controversial subject in many societies, particularly in culturally conservative contexts. In Sri Lanka, discussions around sexuality are frequently avoided in formal and informal settings, leaving young people to rely on peers, social media, or misinformation. This silence creates serious social, health, and psychological consequences. By examining the Sri Lankan context alongside international examples, the importance of comprehensive and age-appropriate sexual education becomes clear.

Understanding Sexual Education

Sexual education goes beyond biological explanations of reproduction. Comprehensive sexual education includes knowledge about human anatomy, puberty, consent, relationships, emotional health, gender identity, sexual orientation, reproductive rights, contraception, prevention of sexually transmitted infections (STIs), and personal safety. Importantly, it also promotes values such as respect, responsibility, dignity, and mutual understanding. When delivered appropriately, sexual education empowers individuals to make informed decisions rather than encouraging early or risky sexual behavior.

The Sri Lankan Context: Silence and Its Consequences

In Sri Lanka, sexual education is included in school curricula mainly through subjects such as Health Science and Life Competencies, however the content is often limited and taught with hesitation. Many teachers feel uncomfortable discussing sexual topics openly due to cultural norms, religious sensitivities, and fear of parental backlash. As a result, lessons are rushed, skipped, or delivered in a purely biological manner without addressing emotional, social, or ethical dimensions.

This lack of open education has led to several social challenges. Teenage pregnancies, although less visible, remain a significant issue, particularly in rural and estate sectors. Young girls who become pregnant often face school dropouts, social stigma, and limited future opportunities. Many of these pregnancies occur due to lack of knowledge about contraception, consent, and bodily autonomy.

Another serious concern in Sri Lanka is child sexual abuse. Numerous reports indicate that many children do not recognize abusive behaviour or lack the confidence and language to report it. Proper sexual education, especially lessons on body boundaries and consent, can help children identify inappropriate behavior and seek help early. In the Sri Lankan context, where respect for elders often discourages questioning authority, this knowledge is especially crucial.

Furthermore, misinformation about menstruation, nocturnal emissions, and bodily changes during puberty causes anxiety and shame among adolescents. Many Sri Lankan girls experience menarche without prior knowledge, leading to fear and confusion. Similarly, boys often receive no guidance about emotional or physical changes, reinforcing unhealthy notions of masculinity and silence around mental health.

Cultural Resistance and Misconceptions

Opposition to sexual education in Sri Lanka often stems from the belief that it promotes immoral behaviour or encourages premarital sex. However, international research consistently shows the opposite: young people who receive comprehensive sexual education tend to delay sexual initiation and engage in safer behaviours. The resistance is therefore rooted more in cultural fear than empirical evidence.

Religious and cultural values are important, but they need not conflict with sexual education. In fact, sexual education can be framed within moral discussions about responsibility, respect, family values, and care for others principles shared across Sri Lanka’s major religious traditions. Ignoring sexuality does not protect cultural values; rather, it leaves young people vulnerable.

International Evidence: Lessons from Other Countries

Several countries demonstrate how effective sexual education contributes to positive social outcomes.

In the Netherlands, sexual education begins at an early age and is age-appropriate, focusing on respect, relationships, and communication rather than explicit sexual activity. As a result, the Netherlands has one of the lowest rates of teenage pregnancy and STIs in the world. Young people are encouraged to discuss feelings, boundaries, and consent openly, both in schools and at home.

Similarly, Sweden introduced compulsory sexual education as early as the 1950s. Swedish programs emphasise gender equality, reproductive rights, and sexual health. This long-term commitment has contributed to high levels of sexual health awareness, low maternal mortality among young mothers, and strong societal acceptance of gender diversity. Sexual education in Sweden is also closely linked to public health services, ensuring access to counseling and contraception.

In many developing contexts, international organisations have supported sexual education as a tool for social development. UNESCO promotes Comprehensive Sexuality Education (CSE) globally, emphasising that it equips young people with knowledge, skills, attitudes, and values that enable them to protect their health and dignity. Studies supported by UNESCO show that CSE reduces risky behaviours, improves academic outcomes, and supports gender equality.

In countries such as Rwanda and South Africa, sexual education has been integrated with HIV/AIDS prevention programs. These initiatives demonstrate that sexual education is not a luxury of developed nations but a necessity for public health and social stability.

Comparing Sri Lanka with International Models

When compared with international examples, Sri Lanka’s challenges are not due to lack of capacity but lack of open dialogue and political will. Sri Lanka has a strong education system, high literacy rates, and an extensive public health network. These strengths provide an excellent foundation for implementing comprehensive sexual education that is culturally sensitive yet scientifically accurate.

Unlike the Netherlands or Sweden, Sri Lanka may not adopt early-age sexuality discussions in the same manner, but age-appropriate education during late primary and secondary school is both feasible and necessary. Topics such as puberty, menstruation, consent, online safety, and respectful relationships can be introduced gradually without violating cultural norms.

Sexual Education in the Digital Era

The urgency of sexual education has increased in the digital age. Sri Lankan adolescents are exposed to sexual content through social media, films, and online platforms, often without guidance. Pornography frequently becomes a primary source of sexual knowledge, leading to unrealistic expectations, objectification, and distorted ideas about consent and relationships.

Sexual education can counter these influences by developing critical thinking, media literacy, and ethical understanding. Teaching young people how to navigate digital relationships, cyber harassment, and online exploitation is now an essential component of sexual education.

Gender Equality and Social Change

Sexual education also plays a crucial role in promoting gender equality. In Sri Lanka, traditional gender roles often limit open discussion about female sexuality while excusing male dominance. Comprehensive sexual education challenges these norms by emphasizing mutual respect, shared responsibility, and equality in relationships.

Educating boys about consent and emotional expression helps reduce gender-based violence, while educating girls about bodily autonomy strengthens empowerment. In the long term, this contributes to healthier families and more equitable social structures.

The Way Forward for Sri Lanka

For sexual education to be effective in Sri Lanka, several steps are necessary. Teachers must receive proper training to handle the subject confidently and sensitively. Parents should be engaged through awareness programs to reduce fear and misconceptions. Curriculum developers must ensure that content is age-appropriate, culturally grounded, and scientifically accurate.

Importantly, sexual education should not be treated as a one-time lesson but as a continuous process integrated into broader life skills education. Collaboration between schools, healthcare providers, religious leaders, and community organisations can help normalise discussions around sexual health while respecting cultural values.

Finally , sexual education is not merely about sex; it is about health, dignity, safety, and responsible citizenship. The Sri Lankan experience demonstrates how silence and taboo can lead to misinformation, vulnerability, and social harm. International examples from the Netherlands, Sweden, and global initiatives supported by UNESCO clearly show that comprehensive sexual education leads to positive individual and societal outcomes.

For Sri Lanka, embracing sexual education does not mean abandoning cultural values. Rather, it means equipping young people with knowledge and ethical understanding to navigate modern social realities responsibly. In an era of rapid social and technological change, sexual education is not optional it is essential for building a healthy, informed, and compassionate society.

A long-running identity conflict flares into full-blown war

Published

on

Ayatollah Ali Khamenei / President Donald Trump

It was Iran’s first spiritual head of state, the late Ayatollah Khomeini, who singled out and castigated the US as the ‘Great Satan’ in the revolutionary turmoil of the late seventies of the last century that ushered in the Islamic Republic of Iran. The core issue driving the long-running confrontation between Islamic Iran and the West has been religious identity and the seasoned observer cannot be faulted for seeing the explosive emergence of the current war in the Middle East as having the elements of a religious conflict.

The current crisis in the Middle East which was triggered off by the recent killing of Iranian spiritual head of state Ayatollah Ali Khamenei in a combined US-Israel military strike is multi-dimensional and highly complex in nature but when the history of relations between Islamic Iran and the West, read the US, is focused on the religious substratum in the conflict cannot be glossed over.

In fact it is not by accident that US President Donald Trump resorts to Biblical language when describing Iran in his denunciations of the latter. Iran, from Trump’s viewpoint, is a primordial source of ‘evil’ and if the Middle East has collapsed into a full-blown regional war today it is because of the ‘evil’ influence and doings of Iran; so runs Trump’s narrative. It is a language that stands on par with that used by the architects of the Iranian revolution in the crucial seventies decade.

In other words, it is a conflict between ‘good’ and ‘evil’ and who is ‘good’ and who is ‘evil’ in the confrontation is determined mainly by the observer’s partialities and loyalties which may not be entirely political in kind. It should not be forgotten that one of President Trump’s support bases is the Christian Right in the US and in the rest of the West and the Trump administration’s policy outlook and actions should not be divorced from the needs of this segment of supporters to be fully made sense of.

The reasons for the strong policy tie-up between Rightist administrations in the US in particular and Israel could be better comprehended when the above religious backdrop is taken into consideration. Israel is the principal actor in the ‘Old Testament’ of the Bible and is seen as ‘the Chosen People of God’ and this characterization of Israel ought to explain the partialities of the Republican Right in particular towards Israel. Among other things, this partiality accounts for the strong defence of Israel by the US.

For the purposes of clarity it needs to be mentioned here that the Bible consists of two parts, an ‘Old’ and ‘New Testament’ , and that the ‘New Testament’ or ‘Message’ embodies the teachings of Jesus Christ and the latter teachings are seen as completing and in a sense giving greater substance to the ‘Old Testament’. However, Judaism is based mainly on ‘Old Testament’ teachings and Judaism is distinct from Christianity.

To be sure, the above theological explanation does not exhaust all the reasons for the war in the Middle East but the observer will be allowing an important dimension to the war to slip past if its importance is underestimated.

It is not sufficiently realized that the Iranian Islamic Revolution of 1979 utterly changed international politics and re-wrote as it were the basic parameters that must be brought to bear in understanding it. So important is the Islamic factor in contemporary world politics that it helped define to a considerable degree the new international political order that came into existence with the collapsing of the Cold War and the disintegration of the USSR .

Since the latter developments ‘political Islam’ could be seen as a chief shaping influence of international politics. For example, it accounts considerably for the 9/11 calamity that led to the emergence of fresh polarities in world politics and ushered in political terrorism of a most destructive kind that is today disquietingly visible the world over.

It does not follow from the foregoing that Islam, correctly understood, inspires terrorism of any kind. Islam proclaims peace but some of its adherents with political aims interpret the religion in misleading, divisive ways that run contrary to the peaceful intents of the faith. This is a matter of the first importance that sincere adherents of the faith need to address.

However, there is no denying that the Islamic Revolution in Iran of 1979 has been over the past decades a great shaper of international politics and needs to be seen as such by those sections that are desirous of changing the course of the world for the better. The revolution’s importance is such that it led to US political scientist Dr. Samuel P. Huntingdon to formulate his historic thesis that a ‘Clash of Civilizations’ is upon the world currently.

If the above thesis is to be adopted in comprehending the principal trends in contemporary world politics it could be said that Islam, misleadingly interpreted by some, is pitting a good part of the Southern hemisphere against the West, which is also misleadingly seen by some, as homogeneously Christian in orientation. Whereas, the truth is otherwise. The West is not necessarily entirely synonymous with Christianity, correctly understood.

Right now, what is immediately needed in the Middle East is a ceasefire, followed up by a negotiated peace based on humanistic principles. Turning ‘Spears into Ploughshares’ is a long gestation project but the warring sides should pay considerable attention to former Iranian President Mohammad Khatami’s memorable thesis that the world needs to transition from a ‘Clash of Civilizations’ to a ‘Dialogue of Civilizations’. Hopefully, there would emerge from the main divides leaders who could courageously take up the latter challenge.

It ought to be plain to see that the current regional war in the Middle East is jeopardising the best interests of the totality of publics. Those Americans who are for peace need to not only stand up and be counted but bring pressure on the Trump administration to make peace and not continue on the present destructive course that will render the world a far more dangerous place than it is now.

In the Middle East region a durable peace could be ushered if only the just needs of all sides to the conflict are constructively considered. The Palestinians and Arabs have their needs, so does Israel. It cannot be stressed enough that unless and until the security needs of the latter are met there could be no enduring peace in the Middle East.

The art and science of communicating with your little child

Published

on

The two input gateways of communication, sight and sound, are quite well developed at birth. In fact, the auditory system becomes functional around 24 weeks in the womb, and the normal newborn can hear quite well after birth. However, the newborn’s vision is a little blurry at birth, and the baby sees the world in shades of grey, while being able only to focus on things 20 to 30 cm (8–12 inches) away. Coincidentally, this is perhaps the exact distance to a mother’s face during breastfeeding. By 2-3 months, there are colour vision capabilities and the ability to track. By 5-8 months, there is depth perception, and by 12 months, there is adult clarity of vision.

By the time a child turns five, his or her brain has already reached 90% of its adult size. This astonishing physical growth is not just happening on its own; it is, to a certain extent, fuelled by experience, and the most vital experience a young child can have is communication with his or her parents.

Modern developmental neuroscience has shifted our understanding of how children learn. We used to think babies were passive sponges, slowly absorbing the world. We now know they are active characters from day one, constantly seeking interaction to build the architecture of their minds. This architecture is not built by apps, vocabulary flashcards, or educational television. It is built through simple, loving, back-and-forth interactions with anyone they come across, but mostly their parents.

The Foundation: Serve and Return (0–12 Months)

Communication with an infant from birth to one year of age begins long before they speak their first word. In the first year, the goal is to master a phenomenon called Serve and Return. This is a basic scenario picked up from the game of tennis. At the start of each game of a set in tennis, a player serves, and the opponent returns the serve. Just imagine a tennis match, where a baby “serves” by making a sound, making eye contact, reaching for a toy, or crying. The job of anyone in the vicinity, who very often are the parents of the baby, is to “return” the ball. If they babble, you babble back. If they point at a cat, you look and say, “Yes, that’s a furry cat!” This simple act does two things. The first is Brain Building, which creates and strengthens neural pathways in the language and emotional centres of the brain. The other is Emotional Security, a thing which teaches a baby that he or she has some help in the learning processes. The baby absorbs the notion that when he or she signals a need, his or her world will respond. This forms the basis of a secure attachment. Scientists have advocated that during this stage, people, especially the parents of a baby, should embrace what is called ‘parentese’. It is the use of a somewhat high-pitched, exaggerated voice. Research has shown that babies pay more attention to parentese than to regular adult speech, helping them to map the sounds of their native language more quickly.

The Language Explosion: Toddlers (1–3 Years)

When a child starts speaking words, the game changes considerably and quite profoundly. This period is defined by a rapid increase in his or her vocabulary and the beginning of grammar. It is very important to narrate everything. The people around, especially the parents, need to become kind of sports commentators for your life. While dressing them, one could say, “First we put on the red sock. After that, we put the other red sock on your left foot.” What we are doing by this is to give them the labels for the world they see.

It is also important to expand, but not truly correct, whatever the child says. If a toddler points to a car and says “Car!”, don’t just say “Yes.” Expand on it: “Yes, that is a big, fast, red car!” You are adding a new vocabulary and grammatical structure through a natural process. If the child says “Me go,” respond with, “Yes, you are going!” rather than correcting and saying “No…, you should say ‘I am going’.”

Toddlers love reading the same book, even one hundred times. While it may be tedious for those around the baby, it is important to realise that such repetition is vital for their learning. They are predicting what comes next, which is a core cognitive skill.

The Preschooler: Building Stories and Logic (3–5 Years)

By age three, the focus shifts from “what” to “why.” Preschoolers are beginning to understand complex emotions, time, and causality. This is the age at which it is best to ask questions which require thought and understanding. Such indirect open-ended questions would sound like “What was the best part of the park today?” or “How do you think that character in the story is feeling?

A preschooler’s world is full of “big feelings” they cannot yet manage. When they are upset because they cannot have a cookie, avoid saying “Don’t cry over nothing.” Instead, name the emotion: “Don’t cry, you can have a cookie after dinner“. This teaches them emotional literacy. Parents and others around in the home could share stories about when they were little, or make up fantasy tales together. Storytelling teaches sequential logic (beginning, middle, end) and strengthens their imagination.

The Absolute Master Class: Learning Through Play

If communication is the fuel for brain development, play is the engine. For a child under five, play is not a break from learning; play is learning. It is how they explore physics (stacking blocks), mathematics (sorting shapes), social dynamics (sharing toys), and language (pretend play). We can boost their development exponentially by weaving communication into their play.

When a child is playing with blocks, dough, or puzzles, they are building fine motor skills and spatial awareness. It is also useful to use three-dimensional words: “Can you put the blue block on top of the red one?” “The puzzle piece is next to your knee.” One could also ask them to describe the texture: “Is the dough soft or hard?

Pretend play, such as acting as a doctor, an engineer, a chef, or a superhero, is one of the most cognitively demanding things a child can do. It requires them to understand symbolic thought and to take on another person’s perspective. Join their world as a supporting character, not the director. If they are the doctor, ask, “Doctor, my teddy bear’s tummy hurts. What should I do?” This encourages them to use vocabulary relevant to the scenario and practice complex social problem-solving.

Playing with water, sand, slime, or safe food products allows children to process sensory information. This is the perfect time for descriptive vocabulary. Use contrasting words: wet/dry, hot/cold, sticky/smooth, loud/quiet.

A few special words for parents. You do not need an expensive degree or specialised toys to build your child’s brain. The most powerful tool you have is your own responsiveness. Modern science tells us that the basic recipe for a thriving child is simple: Look at them when they signal you. Respond with warmth and words. Narrate their world and Join their play.

You are not just talking to your child; you are building his or her future, even via just one conversation at a time. So, go on talking to your child and even make him or her a real-life chatterbox.
