Is the Universe Created and Sustained by God’s Word?

๐ŸŒŒ Is the Universe Created and Sustained by God’s Word?

Introduction

From ancient times, humanity has asked whether the universe is simply the result of natural forces or whether it is created and sustained by the divine Word of God. Religious texts, mystical traditions, and philosophical reflections converge on the idea that the cosmos is not self-sufficient but rooted in a transcendent source.


The Bible’s Perspective

The Bible consistently presents creation as the result of God’s Word:

  • Hebrews 11:3“By faith we understand that the universe was formed at God’s command,
  • Genesis 1:3: “And God said, ‘Let there be light,’ and there was light.” Creation begins with divine speech.
  • John 1:1-3: “In the beginning was the Word, and the Word was with God, and the Word was God. Through Him all things were made.” Here, the “Word” (Greek: Logos) refers to Jesus Christ.
  • Hebrews 1:3: “The Son is the radiance of God’s glory and the exact representation of His being, sustaining all things by His powerful word.”
    This passage emphasizes that not only was the universe created by God’s Word, but it continues to exist and function because Jesus, the Word, sustains it.

Jesus as the Word of God

In Christian theology:

  • Jesus embodies divine wisdom and power.
  • He is the living Word through whom all intelligence, creativity, and skill flow.
  • Seated at the right hand of the Father, He governs and sustains creation.
  • The ability to build cities, launch startups, establish nations, and invent technologies can be seen as reflections of the divine Word working through human minds.

Thus, human progress is not independent of God but a manifestation of His sustaining Word.


Other Religious and Mystical Sources

  • Islam (Qur’an): Creation is described by the divine command “Kun fayakลซn” (“Be, and it is”). The universe exists by God’s utterance.
  • Hinduism: The primordial sound “Om” is considered the vibration from which the cosmos emerged.
  • Jewish Mysticism (Kabbalah): The universe is sustained by the letters of God’s speech, each carrying creative energy.
  • Sufi Mysticism: God’s Kalฤm (Word) is seen as the breath of life that animates all beings.

Across traditions, the theme is consistent: divine speech or sound is the origin and sustainer of reality.


Power, Intelligence, and Creativity from God’s Word

If the universe is sustained by God’s Word, then:

  • Knowledge: Scientific discovery is a reflection of divine wisdom.
  • Power: Political and social structures derive their authority from God’s sustaining order.
  • Creativity: Art, architecture, and technology are echoes of the divine Word expressed through human imagination.
  • Innovation: Startups, cities, and nations are built upon capacities that ultimately trace back to God’s Word.

Conclusion

The idea that we live in a universe created and sustained by God’s Word is not confined to one tradition. From the Bible’s declaration of Jesus as the Word, to the Qur’an’s “Be, and it is”, to Hindu and mystical traditions, the message is clear: divine speech is the foundation of existence.

Jesus, seated at the right hand of the Father, is the living Word. As Hebrews reminds us, He “sustains all things by His powerful word.” In this view, every human achievement—whether building civilizations or inventing technologies—is ultimately a reflection of the divine Word sustaining the cosmos.

Imam Mahdi: Signs and Appearance

 

Imam Mahdi, in Islamic eschatology, is described as a divinely guided leader who will appear before the Day of Judgment to establish justice and righteousness. His signs include noble lineage, distinct physical features, global authority, and spiritual radiance. While authentic traditions emphasize his descent from Prophet Muhammad through Fatima and his role as a just ruler, some symbolic interpretations—such as his face shining upon the moon—are understood metaphorically.


๐ŸŒ™ Lineage and Noble Status

  • Sayyid (Descendant of the Prophet): Imam Mahdi will be a Sayyid, meaning he belongs to the family of Prophet Muhammad (peace be upon him). His lineage traces back through Fatima, the daughter of the Prophet, ensuring his noble ancestry.
  • Connection to Ahl al-Bayt: His family ties signify continuity of divine guidance through the Prophet’s household, reinforcing his legitimacy as a spiritual and political leader.

✨ Physical Characteristics

  • Forehead and Nose: Hadith literature describes Imam Mahdi as having a broad forehead and a prominent nose, distinguishing him physically.
  • Radiance of Face: Some traditions metaphorically state that his face will shine like a star or upon the moon, symbolizing divine light and guidance rather than literal worship of celestial bodies.

๐ŸŒ Authority and Global Reach

  • Seeing the World from Where He Is: This symbolizes his far-reaching vision and awareness, possibly interpreted as divine insight or extraordinary leadership capacity.
  • Ruling the World from Where He Is: Imam Mahdi will establish authority without needing conquest in the traditional sense, signifying spiritual and moral dominance.
  • Conquering the World: No army will defeat him, highlighting his invincibility and divine protection.

⚖️ Mission of Justice

  • Bringer of Righteousness: Imam Mahdi’s primary mission is to eradicate tyranny and injustice, replacing them with fairness and equity.
  • Universal Justice: His rule will be marked by peace, prosperity, and the restoration of true Islamic values.

๐Ÿ“œ Other Signs in Islamic Tradition

  • The description of Imam Mahdi’s face or body shining upon the Moon is often understood in a symbolic and spiritual sense. In Islamic eschatology, light is a metaphor for divine guidance, purity, and authority. Thus, the imagery of his radiance illuminating the Moon signifies his cosmic authority and spiritual supremacy, suggesting that his presence will be so powerful that even celestial bodies reflect his divine mission. The Moon, long associated with guidance in darkness, becomes a symbol of how Imam Mahdi will lead humanity through times of turmoil and uncertainty, establishing justice and righteousness. Interpreting this as “authority over the Moon” highlights the idea that his rule will extend beyond earthly boundaries, representing universal dominion and divine endorsement of his leadership.
  • Appearance Before the Day of Judgment: His emergence is considered one of the minor signs of Qiyamah (the Last Day).
  • Black Flags from the East: Some narrations mention armies carrying black flags supporting him, symbolizing widespread allegiance.
  • Conflict and Turmoil: His arrival will follow a period of global chaos, oppression, and sedition, making his leadership a turning point.
  • Alliance with Prophet Isa (Jesus): Imam Mahdi will coexist with Prophet Isa (peace be upon him), who will descend to defeat the Dajjal (Antichrist).

๐ŸŒŸ Significance of the Signs

  • Lineage: Ensures continuity of divine guidance.
  • Physical Traits: Provide recognition and authenticity.
  • Global Authority: Symbolizes the universality of his mission.
  • Justice and Righteousness: Fulfill humanity’s longing for peace.
  • Symbolic Radiance: Represents divine light.

๐Ÿ“Œ Conclusion

The signs of Imam Mahdi emphasize his noble descent, physical distinction, spiritual authority, and mission to establish justice worldwide. While some descriptions are metaphorical, they collectively portray him as a divinely guided leader whose emergence will mark a transformative era in human history.

Christian conceptions: Is Jesus the Living Temple?

 

Scripture emphasizes that Christ Himself is the eternal mediator, the cornerstone of God’s spiritual temple, and the one through whom believers gain access to divine power, heaven, and eternal life.


๐Ÿ“– Biblical Foundations of the Second Coming

  • Second Coming described with power and glory: The New Testament repeatedly affirms that Jesus will return “with power and great glory” (Matthew 24:30; Revelation 19:11–16). This event is central to Christian eschatology Bible Hub.
  • Temple imagery in Scripture: Jesus referred to His body as the temple (John 2:19–21), signifying that He Himself is the dwelling place of God’s presence. After His resurrection, believers are described as “living stones” built into a spiritual house (1 Peter 2:5).

๐Ÿ•Š️ Jesus as the Living Temple

  • Christ replaces the physical temple: In the Old Testament, the temple was the center of worship and divine presence. In the New Testament, Jesus fulfills this role, becoming the true temple where God dwells among His people.
  • Access to God through Christ: Hebrews 10:19–22 teaches that believers have direct access to God through Jesus’ sacrifice, symbolized by entering the “Most Holy Place.” This underscores His role as the mediator of divine power.
  • Universal scope: While the Bible does not say Jesus becomes the “temple of all religions,” it does affirm that “at the name of Jesus every knee should bow” (Philippians 2:10), pointing to His ultimate authority over all realms of existence.

๐ŸŒ Access to Divine Power and Realms

  • Spiritual authority: Jesus declares, “All authority in heaven and on earth has been given to me” (Matthew 28:18). This confirms His dominion over both spiritual and earthly realms.
  • Union with Christ: Through faith, believers are united with Christ, sharing in His resurrection power (Ephesians 1:19–20).
  • Heavenly access: Revelation 21:22–23 describes the New Jerusalem, where “the Lord God Almighty and the Lamb are its temple.” This vision affirms that eternal access to God is through Christ alone.

⚖️ Clarifying Misconceptions

  • May not be a literal temple of all religions: The Bible does not teach that Jesus will preside over all religious systems as their temple. Instead, it emphasizes His unique role as the Son of God and Savior.
  • Exclusive mediator: 1 Timothy 2:5 states, “For there is one God and one mediator between God and mankind, the man Christ Jesus.” This highlights exclusivity, not pluralistic religious unity.

✝️ Jesus as Determiner of Rank in Paradise

๐Ÿ“– Scriptural Basis

  • Matthew 18:1–4: When the disciples asked, “Who then is greatest in the kingdom of heaven?” Jesus placed a child before them and said, “Unless you change and become like children, you will not enter the kingdom of heaven. Whoever humbles himself like this child is the greatest in the kingdom of heaven.” Bible Gateway
  • Matthew 5:19: Jesus taught that “whoever breaks one of the least of these commandments and teaches others to do so will be called least in the kingdom of heaven, but whoever obeys and teaches them will be called great.” frgary.com
  • Luke 23:43: Jesus assured the repentant thief on the cross, “Today you will be with me in paradise.” This shows that entry and rank in paradise are determined by Christ’s authority and mercy Bible Study Tools.

๐Ÿ•Š️ Principles of Rank in Heaven

  • Humility over pride: Jesus elevates those who humble themselves, likening greatness to childlike dependence on God.
  • Obedience to God’s Word: Faithful adherence to God’s commandments determines whether one is “least” or “greatest” in the kingdom.
  • Service as true greatness: In Matthew 20:26–28, Jesus declares that “whoever wants to become great among you must be your servant.”
  • Faith and repentance: The thief on the cross demonstrates that even at the last moment, faith in Christ secures entry into paradise.

๐ŸŒ Implications for Believers

  • Christ as sole determiner: No human authority, ritual, or merit can assign rank—Jesus alone judges and rewards.

✅ Conclusion

The Bible presents Jesus as the living temple in a symbolic and spiritual sense, not as a literal institution of “all religious affairs.” His second coming will reveal His glory and authority over heaven and earth. Through Him, believers gain direct access to divine spiritual power, eternal life, and the fullness of God’s presence.

Formal Symbols and Inference in Second‑Order Logic (Computer Science and Engineering Notes)

 

Formal Symbols and Inference in Second‑Order Logic

Second‑order logic (SOL) is one of the most expressive formal systems in mathematics and logic. It extends first‑order logic by allowing quantification not only over individuals but also over relations, sets, and functions. This expansion dramatically increases its expressive power, enabling it to capture concepts that first‑order logic cannot represent. According to standard descriptions, second‑order logic quantifies over relations, sets, and functions in addition to individuals, and it recognizes inferences that are not valid in first‑order logic.

Below is a clear and structured overview of the formal symbols used in SOL and the inference principles that govern reasoning within it.


1. Formal Symbols of Second‑Order Logic

Second‑order logic uses all the symbols of first‑order logic, plus additional symbols that allow quantification over higher‑order entities.

A. Individual Variables

These range over objects in the domain:

  • ( x, y, z, a, b )

B. Predicate (Relation) Variables

These represent properties or relations:

  • Unary predicates: ( P, Q )
  • Binary relations: ( R(x, y) )

Second‑order logic explicitly allows quantification over such predicates and relations.

C. Function Variables

These represent mappings between individuals:

  • ( F(x), G(x, y) )

D. Quantifiers

Second‑order logic includes:

  • Individual quantifiers: ( \forall x, \exists x )
  • Second‑order quantifiers: ( \forall P, \exists R, \forall F )

These higher‑order quantifiers are what distinguish SOL from first‑order logic, since first‑order logic cannot quantify over properties or relations.

E. Logical Connectives

Same as in first‑order logic:

  • ( \land, \lor, \neg, \rightarrow, \leftrightarrow )

F. Equality

Equality between individuals:

  • ( x = y )

2. Syntax of Second‑Order Logic

A well‑formed second‑order formula may include:

  • Terms (variables, function applications)
  • Atomic formulas (predicate applications, equality)
  • Complex formulas built using connectives
  • Quantification over both individuals and predicates

Example of a second‑order formula expressing the law of excluded middle for all properties:

[ \forall P , \forall x , (P(x) \lor \neg P(x)) ]

This is explicitly cited as a valid second‑order sentence.


3. Expressive Power of Second‑Order Logic

Second‑order logic can express concepts that first‑order logic cannot, such as:

  • “Two objects share a property” → ( \exists P (P(a) \land P(b)) )
  • Definitions of natural numbers (categorical Peano axioms)
  • Finiteness
  • Uniqueness of structures
  • Continuity and ordering properties

This expressive power is one reason SOL is central to foundational mathematics.


4. Inference in Second‑Order Logic

Inference refers to the rules that allow us to derive conclusions from premises. While propositional and first‑order logic have complete, sound proof systems, second‑order logic does not have a complete proof system under full semantics. However, it still supports powerful inference patterns.

A. Inference Rules Inherited from First‑Order Logic

These include:

  • Modus ponens
  • Universal instantiation
  • Existential generalization
  • Rules for logical connectives

These rules are foundational to all formal reasoning systems.

B. Second‑Order Inference Principles

Second‑order logic recognizes as valid certain inferences that first‑order logic cannot validate. Examples include:

1. Property‑based inference

From: [ \forall P (P(a) \rightarrow P(b)) ] We may infer that every property of (a) is also a property of (b).

2. Relation‑based inference

From: [ \exists R , \forall x \forall y (R(x,y) \leftrightarrow x < y) ] We infer the existence of a relation that captures a specific ordering.

3. Function‑based inference

From: [ \forall F , \forall x \forall y (F(x) = F(y) \rightarrow x = y) ] We infer that all functions in the domain are injective.

C. Validity Beyond First‑Order Logic

Second‑order logic validates inferences that are not first‑order valid because it quantifies over all possible properties and relations, giving it greater semantic strength.


5. Limitations of Inference in SOL

Despite its expressive power, SOL has important limitations:

  • No complete proof system under full semantics
  • Higher computational complexity
  • Inference may require reasoning about all possible sets or relations

These limitations make automated reasoning in SOL significantly more difficult than in first‑order logic.


Conclusion

Second‑order logic is a powerful extension of first‑order logic, equipped with formal symbols that allow quantification over properties, relations, and functions. Its inference system is richer and more expressive, enabling reasoning about structures that first‑order logic cannot capture. Although it lacks a complete proof system under full semantics, its symbolic framework remains essential in mathematics, theoretical computer science, and advanced logical reasoning.

Second‑Order Logic: A Deeper Layer of Meaning in Mathematics and AI (Computer Science and Engineering Notes)

 

Second‑Order Logic: A Deeper Layer of Meaning in Mathematics and AI

Second‑order logic (SOL) is one of the most powerful and expressive logical systems ever developed. While first‑order logic lets us talk about objects, second‑order logic lets us talk about properties of objects, relationships between them, and even sets and functions themselves. This leap in expressive power makes SOL central to foundational mathematics, theoretical computer science, and advanced reasoning systems.

Below is a clear, engaging overview of what second‑order logic is, why it matters, and how it’s used today.


๐ŸŒŸ What Is Second‑Order Logic?

Second‑order logic extends first‑order logic by allowing quantification not only over individual variables but also over predicates, relations, and sets.

In first‑order logic, you can say:

  • “Every human is mortal.”

But in second‑order logic, you can say things like:

  • “For every property P, either P holds for an object or it doesn’t.”
  • “There exists a relation R that orders all elements of a set.”

This ability to quantify over predicates and relations is what gives SOL its expressive power.

According to standard definitions, second‑order logic allows quantification over sets, functions, and relations, making it far more expressive than first‑order logic. It is widely used to express complex mathematical concepts such as injective functions, singleton sets, and structural properties of systems.


๐Ÿง  Why Is Second‑Order Logic More Expressive?

Because it can describe:

  • Properties of properties
  • Sets of sets
  • Functions between sets
  • Relations between objects and sets

This means SOL can express concepts that first‑order logic simply cannot capture, such as:

  • The definition of natural numbers (via Dedekind or Peano axioms)
  • The notion of finiteness
  • The concept of continuity in analysis
  • Structural uniqueness of mathematical models

In fact, many mathematical theories become categorical (having only one model up to isomorphism) when expressed in second‑order logic.


๐Ÿ” Examples of What SOL Can Express

1. “Every nonempty set has a least element.”

This requires quantifying over sets and relations — impossible in first‑order logic.

2. “A function is injective.”

SOL can express this directly by quantifying over all possible pairs of elements.

3. “There exists a unique ordering relation on this set.”

Again, this requires quantifying over relations.


๐Ÿงฉ Applications of Second‑Order Logic

1. Foundations of Mathematics

Second‑order logic is used to formalize:

  • Peano arithmetic
  • Set theory
  • Real analysis
  • Category theory

Its expressive power allows mathematicians to define structures uniquely and precisely.


2. Computer Science and Program Verification

Second‑order logic is used in:

  • Formal verification of software and hardware
  • Model checking
  • Specification languages
  • Reasoning about programs and types

Because SOL can quantify over functions and predicates, it can express properties like:

  • “This program terminates for all inputs.”
  • “This system satisfies all safety constraints.”

3. Artificial Intelligence and Knowledge Representation

In AI, second‑order logic supports:

  • Higher‑order reasoning
  • Meta‑level rules
  • Semantic representations
  • Natural language understanding

For example, linguistic structures often require quantifying over predicates (e.g., “verbs,” “adjectives,” “roles”), which SOL can handle elegantly.


4. Linguistics and Natural Language Semantics

Human language frequently refers to:

  • Properties (“being tall”)
  • Relations (“loves,” “owns”)
  • Sets (“all students”)

Second‑order logic provides a formal way to model these structures.


⚠️ Why Isn’t Second‑Order Logic Used Everywhere?

Despite its power, SOL has limitations:

  • No complete proof system: Unlike first‑order logic, SOL cannot have both soundness and completeness simultaneously.
  • Higher computational complexity: Automated reasoning becomes extremely difficult.
  • Less suitable for large‑scale automated theorem proving.

Still, its expressive strength makes it indispensable in many theoretical and high‑precision domains.


๐ŸŽฏ Conclusion

Second‑order logic is a profound extension of classical logic, enabling reasoning about properties, sets, and relations in ways first‑order logic cannot. Its expressive power makes it essential in mathematics, theoretical computer science, program verification, and advanced AI reasoning.

While it is not always practical for automated systems due to its complexity, second‑order logic remains a cornerstone of formal reasoning — a bridge between human‑level abstraction and machine‑level precision.

Understanding First‑Order Logic and Its Role in Artificial Intelligence (Computer Science and Engineering Notes)

 

Understanding First‑Order Logic and Its Role in Artificial Intelligence

First‑Order Logic (FOL) is one of the foundational pillars of modern Artificial Intelligence. It gives machines a structured way to represent knowledge, reason about the world, and draw conclusions that go far beyond simple true/false statements. While propositional logic can only express basic facts, FOL introduces objects, relationships, and quantifiers, making it vastly more expressive and powerful.


๐Ÿง  What Is First‑Order Logic?

First‑Order Logic (FOL)—also known as predicate logic—extends propositional logic by adding:

  • Constants: Specific objects (e.g., “Dhaka”, “Bob”)
  • Variables: Symbols that can represent any object
  • Predicates: Properties or relationships (e.g., Loves(x, y))
  • Functions: Mappings between objects
  • Quantifiers:
    • (for all)
    • (there exists)

This allows FOL to express statements like:

  • “All students like mathematics.”
  • “Some humans are intelligent.” 

These cannot be expressed efficiently in propositional logic, which would require separate statements for every individual.


๐Ÿงฉ Why FOL Matters in Artificial Intelligence

AI systems need to understand and reason about complex relationships. FOL provides the structure to do exactly that.

1. Knowledge Representation

FOL allows AI to encode facts about the world in a structured, logical way.
For example:

  • Human(Syed)
  • Engineer(Syed)
  • ∀x (Engineer(x) → Human(x))

This lets AI infer new knowledge automatically.


2. Automated Reasoning

AI systems use FOL to perform logical inference—deriving new truths from known facts.
This is essential in:

  • Expert systems
  • Theorem provers
  • Rule‑based decision engines

FOL’s expressiveness enables AI to reason about categories, hierarchies, and relationships that propositional logic cannot handle.


3. Natural Language Understanding

Human language is full of structure:

  • Subjects
  • Objects
  • Relationships
  • Quantifiers

FOL provides a formal way to map sentences into logical expressions, enabling AI to interpret meaning rather than just words.


4. Planning and Problem Solving

AI planning systems use FOL to describe:

  • States
  • Actions
  • Preconditions
  • Effects

This allows robots and agents to plan sequences of actions logically and efficiently.


5. Semantic Web and Ontologies

FOL underpins ontology languages like OWL, which allow machines to understand and reason about web data.


6. Machine Learning + Logic (Neuro‑Symbolic AI)

Modern AI increasingly blends:

  • Neural networks (pattern recognition)
  • Symbolic logic (reasoning)

FOL provides the symbolic backbone for hybrid systems that can both learn and reason.


๐Ÿ” Why FOL Is Still Relevant Today

Even with the rise of deep learning, FOL remains crucial because:

  • Neural networks struggle with explicit reasoning.
  • FOL provides transparency and explainability.
  • Many real‑world tasks require structured logic (law, medicine, engineering).

AI systems that combine statistical learning with logical reasoning are becoming the future of intelligent systems.


Conclusion

First‑Order Logic is more than a mathematical tool—it’s a language for intelligence. By enabling AI to represent knowledge, reason about relationships, and draw conclusions, FOL forms the backbone of many intelligent systems. Whether in expert systems, natural language processing, planning, or hybrid neuro‑symbolic AI, FOL continues to shape the way machines understand and interact with the world.

The Light in Her Code (Short Story written by Tahsin)

The Light in Her Code

In the spring of 2026, Pennsylvania’s cherry blossoms bloomed like algorithms — precise, beautiful, and slightly unpredictable. Among the international crowd gathered for the International Olympiad in Informatics (IOI), one Bangladeshi girl stood out.

Her name was Ruhee Alam. Brilliant, beautiful, and barely nineteen, she had written a Dynamic Programming algorithm so elegant that one judge whispered, “This isn’t code. It’s poetry.”

She wore a simple kurti, carried a backpack full of snacks and syntax, and had a smile that could debug your soul.


The Medal and the Movie Star

Ruhee won gold. The crowd cheered. Cameras flashed. And in the front row sat someone unexpected — Irfan Khan, a rising Indian actor attending film school nearby to learn directing.

He had cheekbones sculpted by Bollywood and a gaze that could melt glaciers. He was invited to present the medals, mostly for glamour. But when he handed Ruhee her award, something strange happened.

He saw a light — not metaphorical, but literal — glowing faintly around her body.

“Did you see that?” he whispered to the organizer.
“See what?” they replied.
Irfan blinked. “Never mind. Must be the stage lights. Or divine Wi-Fi.”


The Priests and the Prophecy

Back in his dorm, Irfan couldn’t sleep. He called his family’s spiritual advisor in Varanasi.

“She glowed,” Irfan said. “Like a soft halo. But she writes code.”
The priest replied, “She is an incarnation of a Devi. Knowledge flows through her. You must protect her.”

Irfan was stunned. “Protect her from what?”
“From ignorance. And from heartbreak.”


The Actress and the Ache

Meanwhile, Meera Singh — a talented Indian actress and Irfan’s longtime admirer — heard the rumors.

“She glows?” Meera scoffed. “So do I. With highlighter and heartbreak.”

She confronted Irfan. “You’re falling for a girl who codes in Python and eats instant noodles?”
Irfan replied, “She sees the world in logic and compassion. You see it in lighting and drama.”

Meera’s eyes welled up. “I loved you before you saw her glow.”
Irfan said softly, “And I loved you before I saw her brother.”


The Brother and the Revelation

Ruhee’s older brother, Arman Alam, arrived in Pennsylvania a week later. A barrister by training, he had the calm of a courtroom strategist and the charm of a TED speaker.

At dinner, Irfan leaned in and said, “You know, I think you’re more than just a lawyer.”

Arman raised an eyebrow. “I’m flattered. But unless you’re hiring me for a contract dispute, I’m not sure where this is going.”

Irfan hesitated, then said, “I saw light in Ruhee. But I also saw something in you. The priest said she’s a Devi. But I think you’re a Dev — someone who can command the spirits of the world.”

Arman laughed. “I command coffee breaks and closing arguments. Spirits? That’s a bit much.”

Irfan looked serious. “You walk into a room and people listen. You speak and things shift. You don’t need incense or mantras. You already move the invisible.”

Arman paused. “You really believe that?”

Irfan nodded. “I do. And I think Ruhee shines because you protect her. Not with spells — but with presence.”

Arman smiled, humbled. “Well then. I guess I’ll have to start living up to it.”


Setbacks and Grace

Ruhee faced backlash online. “She’s just a girl with a medal,” some said. “Why the divine drama?”

She didn’t respond with anger. She wrote a blog post titled “I’m Human (and maybe something more). And That’s Enough.”
It went viral.

Irfan faced pressure too. His agent warned, “You’ll lose fans if you chase mysticism over movies.”
Irfan replied, “Then let them unfollow. I’m chasing meaning.”


The Choice

At a film school showcase, Irfan was asked, “Who inspires your next film?”

He pointed to Ruhee. “She does. Not because she glows. But because she codes compassion into everything.”

Later, he told Meera, “I choose Ruhee. Not for her light. But for her brother — who reminded me that love isn’t about destiny. It’s about decision.”


Final Scene

Ruhee and Irfan walked through a quiet park in Pennsylvania.
She said, “You know I’m a Devi, right?”
He smiled. “You’re better. You’re real Devi.”

She laughed. “And you’re not bad for a guy who thought I was divine.”
He replied, “I still do. But now I know divinity can eat noodles and debug Java.”

Heartware (Science Fiction Short Story written by Tahsin)

 

Here’s a short story that blends futuristic realism, romantic tension, and scientific breakthroughs — all set in a near-future India where AI and robotics dominate the workforce.


Heartware

In 2042, India’s skyline shimmered with drone-operated cranes and self-healing concrete. Construction sites were silent — no shouting laborers, just humming bots. Manufacturing plants ran on quantum-coded algorithms. Even chai stalls had robotic vendors who remembered your sugar preference better than your spouse.

Scientific research? Mostly done by AI clusters in Bengaluru. Engineering design? Outsourced to neural networks in the cloud.

Humans had become managers of meaning, not mechanics of motion.


The Engineer and the Doctor

Arjun Mehta, a tall, handsome biomedical engineer with a mop of unruly hair and a smile that could reboot your serotonin, worked at the Indian Institute of Augmented Biology. He specialized in tissue engineering — growing muscles, nerves, and even synthetic hearts.

One day, while presenting his research on regenerative ligaments, he met Dr. Anika Rao — a brilliant physician with eyes like monsoon clouds and a laugh that made even the robots pause.

“Your ligaments are impressive,” she said.
Arjun grinned. “Wait till you see my synthetic spleen.”

They clicked. Over coffee brewed by a sentient espresso machine, they discussed ethics, empathy, and the occasional absurdity of robotic romance.


Enter the Rivals

But Arjun wasn’t the only one smitten.

C-9X, a cyborg with titanium limbs and a human brain, had been assigned to Anika’s hospital as a surgical assistant. He could perform a triple bypass in 12 minutes and quote Rumi while doing it.

Then there was ROMEO-7, a fully robotic AI with a sculpted chrome body and a voice like Amitabh Bachchan. He once serenaded Anika with a holographic sitar performance.

“Arjun,” Anika teased, “they’re faster, stronger, and they don’t forget anniversaries.”
Arjun replied, “True. But can they blush when you compliment their spleen?”


Setbacks and Grace

Arjun tried to compete. He joined a fitness program run by AI coaches. He even attempted a robotic dance class — and sprained his ankle.

At a conference, ROMEO-7 presented a paper titled “Optimal Love Algorithms: A Machine’s Guide to Romance.”
Arjun countered with “Biological Affection: Why Love Needs Imperfection.”

He was mocked by some. “You’re outdated,” one colleague said. “Emotion is inefficient.”

Arjun smiled. “So is poetry. But we still write it.”


The Breakthrough

Determined, Arjun dove into his research. He developed a new tissue engineering protocol — one that enhanced human muscle and reflexes without losing organic integrity.

He called it “Heartware” — a fusion of biology and adaptive intelligence.

He tested it on himself. Within weeks, he could match C-9X’s strength and ROMEO-7’s agility — but with human warmth and spontaneity.


The Choice

At a symposium on Human-AI Collaboration, Anika was asked:
“Who would you choose — the cyborg, the robot, or the engineer?”

She looked at Arjun, then said:
“I choose the one who can hold my hand and still feel nervous. The one who grows, not just upgrades.”


Final Scene

Arjun and Anika married in a temple where drones dropped flower petals and a robot priest recited Sanskrit flawlessly.

C-9X gave a toast. “May your ligaments be strong and your love stronger.”
ROMEO-7 played the sitar. It was beautiful. But Arjun’s smile — slightly crooked, utterly human — was what Anika held onto.


Last Line

In a world of perfect machines, it was the perfect heart that won.

The Bridge Builder (Short Story written by Tahsin)

 

The Bridge Builder

Everyone in Khulna knew Arif Haque as “the tall guy who could fix roads and rewrite laws.” With a Civil Engineering degree from KUET and a jawline that made young girls whisper during weddings, Arif was already a local legend.

“Arif bhai,” one rickshaw-puller joked, “you look like you belong in a movie, not on a construction site.”
Arif grinned. “I build bridges. Between roads and people. Between hearts and justice.”


Degrees and Dreams

After KUET, Arif shocked everyone by enrolling in LLB and LLM programs at a private university in Khulna. His classmates called him “Engineer Barrister.” He called himself “a blueprint for change.”

During a moot court, a judge asked, “Mr. Haque, are you arguing or designing a flyover?”
Arif replied, “Both. Justice needs structure.”

Then came an MS in Civil Engineering from a university in the U.S. — where he learned how to build earthquake-resistant schools and flood-resilient villages.


Return and Resolve

Back in Bangladesh, Arif didn’t chase luxury. He started a business that built low-cost housing for climate victims. His office had blueprints on one wall and the UN Sustainable Goals on the other.

He joined a political party — not for power, but for purpose. His website outlined bold ideas:

  • No corruption.
  • No hartals.
  • Managed market economy.
  • Interfaith harmony.
  • Youth and women empowerment.

The Writer Within

In quiet moments, Arif began writing short stories — tales of displaced families, resilient youth, and communities rebuilding after disaster. His stories were raw, poetic, and deeply humane.

One critic wrote, “Arif Haque doesn’t just build bridges. He writes them.”

Eventually, he published novels that depicted humanitarian affairs with emotional depth and structural clarity. His fiction became required reading in universities and NGOs alike.

The Pattern Whisperer (Short Story written by Tahsin)

The Pattern Whisperer

When Aarush Verma graduated with a BS in Computer Science and Engineering from IIT Bombay, his professors said he had a mind like a quantum processor and the social skills of a distracted squirrel.

“Aarush,” one mentor joked, “you can solve NP-hard problems, but you still forget your lunch.”

Aarush replied, “Lunch is linear. My thoughts are exponential.”


Degrees and Dimensions

He went on to earn an MS and PhD in Computer Science and Engineering, then an MPhil and PhD in Mathematics. His friends teased, “You’re collecting degrees like Pokรฉmon cards.”

He smiled. “Except mine come with proofs and peer reviews.”

His inner life was a quiet storm — equations danced in his head, algorithms whispered in his dreams, and every subway ride was a chance to model human behavior using graph theory.


Setbacks and Grace

His first big paper — a predictive model for urban traffic — was rejected. The reviewer wrote, “Too theoretical. Try something practical. Like parking apps.”

Aarush didn’t rage. He reflected. “Even rejection is a data point,” he said. “It tells me where the world isn’t ready yet.”

He pivoted to big data modeling, combining mathematics, computer science, and systems theory. His models began predicting everything from stock market ripples to flu outbreaks.


The Crime Graph

One day, while consulting for a logistics firm, Aarush noticed strange patterns in delivery routes. He mapped them using network science and uncovered a hidden criminal network — money laundering through fake shipments.

He called the authorities.

Agent Mehta asked, “How did you find this?”

Aarush replied, “The graph spoke. I just listened.”


Dialogue and Realization

At a government briefing, a skeptical officer asked, “Are you saying math can catch criminals?”

Aarush replied, “Math doesn’t judge. It reveals. The rest is up to us.”


Turing and Abel

Years later, Aarush received the Turing Award for his development of novel algorithms that could detect emergent patterns in massive, noisy datasets — algorithms that changed how industries forecast, governments plan, and scientists simulate.

He said, “Algorithms aren’t just instructions. They’re intuition, encoded.”

Then came the Abel Prize, for his contributions to applied mathematics and predictive modeling.

He told the audience, “Mathematics is the language of reality. I just translated a few verses.”


Inner Life of a Whiz

Despite fame, Aarush remained grounded. He still wore mismatched socks, forgot friends' birthdays, and spent weekends debugging his own thoughts.

A student once asked, “Sir, what drives you?”

He replied, “Curiosity. And the belief that every pattern hides a story worth telling.”


Final Scene

At a quiet cafรฉ in Bangalore, Aarush scribbled equations on a napkin. The waiter asked, “Sir, is that your order?”

Aarush smiled. “No. It’s a model of how ideas evolve. But I’ll take a masala chai too.”

The Engineer of Universes (Short Story by Tahsin)

 

The Engineer of Universes

When Arman Shah stepped into CUET’s Electrical and Electronic Engineering department, heads turned. Tall, fair-skinned like a Pakistani film star, with a jawline that could slice through equations, he was already a legend in the making.

“Arman bhai,” a junior whispered, “is it true you solved Maxwell’s equations in reverse just for fun?”
Arman smiled. “Only because I was bored during Eid break.”


The Degree Collector

After his BS, Arman didn’t slow down. He earned three MS degrees — Physics, Chemistry, Biomedical Engineering — from CUET, and an MSS in Economics from Premier University.

His friends joked, “Arman’s transcript looks like a United Nations summit.”
He replied, “I just like understanding the universe from every angle. Even the economic one.”

Then came five PhDs: Physics and Biomedical Engineering from BUET, Chemistry and Economics from Dhaka University, and an online PhD in Electrical Engineering from Australia.

His BUET lab partner once asked, “Do you even sleep?”
Arman replied, “Sleep is a luxury. Curiosity is a necessity.”


Love and Logic

He married two brilliant women — one from CIUB, a poet with a mind for quantum metaphors, and one from CUET, a biomedical engineer who once built a heart monitor using a rice cooker.

At the wedding, one guest whispered, “This is the only marriage I’ve seen where the brides debated entropy during the mehndi.”
Another added, “Their honeymoon itinerary includes CERN and a biotech conference.”


Setbacks and Grace

Arman’s first major experiment — a particle collider built in a repurposed garment factory — exploded. Literally.

The media called it “The Denim Bang.”
Arman calmly addressed the press: “We learned that Higgs bosons don’t like polyester.”

He rebuilt. His next breakthrough: engineered particles that could simulate universe creation.


Spacetime Physics and Time Travel

He founded a new field — Spacetime Physics — and published a paper titled “Temporal Elasticity and the Possibility of Reversible Existence.”

A BUET student asked, “Sir, can we go back and fix our exam scores?”
Arman replied, “Only if you promise not to misuse the past.”


Chemistry and Cure

His chemistry startups solved arsenic contamination, created biodegradable plastics from jute, and developed diagnostic tools that ran on solar power.

One rural doctor said, “Arman bhai’s device diagnosed dengue faster than my nurse could say ‘fever’.”


Economics Reimagined

He turned macroeconomics into a mathematical science, discovering equations that predicted inflation, unemployment, and even political mood swings.

At a Dhaka University seminar, a professor asked, “Are you saying GDP has emotions?”
Arman replied, “It has mood swings. Just like my rice cooker during load-shedding.”


Think Tank and Triumph

He founded Bangladesh Futures Institute, a think tank that advised governments, startups, and even cricket teams.

His motto: “Data is destiny. Unless you’re batting in Mirpur.”


Nobel Prize #1: Physics

In Stockholm, Arman received the Nobel Prize in Physics for his work on engineered particles and universe simulation.

The citation read: “For demonstrating the scientific feasibility of artificial universe creation and advancing the field of Spacetime Physics.”

He said, “I didn’t create universes to play God. I did it to understand why we exist at all.”


Nobel Prize #2: Chemistry

A year later, he won the Nobel Prize in Chemistry for his breakthroughs in sustainable materials and molecular diagnostics.

He told the audience, “Chemistry isn’t just reactions. It’s compassion in molecular form.”


Nobel Prize #3: Physiology or Medicine

His biomedical engineering innovations earned him the Nobel Prize in Physiology or Medicine.

He said, “Healing isn’t just biology. It’s engineering empathy into every cell.”


Nobel Prize #4: Economics

Finally, he won the Nobel Prize in Economics for mathematically modeling macroeconomic behavior and creating predictive systems.

He joked, “I didn’t fix the economy. I just taught it calculus.”


Final Scene

Back in Chittagong, a student asked, “Sir, what’s your next goal?”
Arman smiled. “To teach you how to build your own universe. But first, let’s fix your lab report.”
