Your Body Has a Measuring Tape — The Amazing Mathematics Within Us

Your Body Has a Measuring Tape

The Amazing Mathematics Within Us

Have you ever noticed that your own body can be used as a measuring instrument?

No ruler.

No measuring tape.

No scale.

Just your hands, arms, feet and fingers.

Long before centimetres and inches became standard units, people discovered that the human body offered convenient ways to estimate length. Some of these relationships are surprisingly close for many people.

It is almost as though we carry a small measuring tape within us.

Your Foot and Your Forearm

Try placing your foot beside your forearm.

For many people, the lengths are remarkably similar.

This is not an exact biological rule—human proportions vary—but the resemblance helps explain why body-based measurements became so useful.

The foot became a unit of measurement, while the distance from the elbow to the fingertips gave rise to the cubit, one of the oldest units used by civilizations across the world.

Your Arm Span and Your Height

Now stretch both arms sideways.

Measure from the tip of one middle finger to the other.

For many people, the arm span comes surprisingly close to their height.

This relationship became famous through Leonardo da Vinci's Vitruvian Man, inspired by the Roman architect Vitruvius.

The drawing places the human figure within a square and a circle, turning anatomy into geometry.

But again, it is a proportion, not a law. Some people have longer arms; others have shorter ones.

Nature works with patterns, not identical templates.

Your Hand — A Natural Ruler

Your hand contains several convenient measurements.

The width across four fingers gives a handbreadth.

The distance from the tip of the thumb to the tip of the little finger when the hand is stretched gives a span.

The width of a finger itself could serve as a small unit.

Imagine a craftsman centuries ago needing to estimate the length of a piece of wood.

He could simply use his hand.

No measuring tape required.

The Cubit

The cubit, traditionally measured from the elbow to the tip of the middle finger, was particularly useful.

Different civilizations had different versions of the cubit, so it was never a universally fixed length.

Yet the principle was ingenious: the measuring instrument was always with you.

Builders, craftsmen and traders could carry their basic scale wherever they went.

The Human Figure as Geometry

Artists went further.

Classical artistic traditions developed systems for dividing the human figure into proportional units. One famous convention represented the adult figure as approximately eight head-lengths tall.

It is an artistic ideal, not a measurement that fits everyone.

Children, for instance, have proportionally larger heads, while adults vary considerably in leg, torso and head proportions.

But such systems gave artists a framework for constructing the human figure.

Leonardo's Wonderful Experiment

Leonardo da Vinci took this fascination with proportion to another level.

His Vitruvian Man was not simply a beautiful drawing. It expressed the idea that the human body possessed relationships that could be described mathematically.

A person.

A square.

A circle.

Geometry and anatomy meeting in a single image.

Leonardo was exploring something that had fascinated thinkers for centuries: whether the proportions of the human body reflected a deeper order in nature.

Even the Face Has Proportions

Look at your face in a mirror.

The eyes, nose, mouth, forehead and chin occupy a remarkably organized arrangement.

Anatomists and artists have long studied these relationships.

But there is no single formula for a beautiful face.

Human variation is enormous—and that is precisely what makes faces recognizable and individual.

Mathematical proportion gives structure.

Variation gives character.

Why Do These Relationships Exist?

The human body is an integrated biological system.

Bones, muscles and tissues develop in relation to one another, influenced by genetics, nutrition, hormones, age and many other factors.

So these proportions are not evidence of a literal measuring grid hidden inside us.

They are patterns that emerge from biological growth.

And the patterns are fascinating.

The Body Was Our First Measuring Tool

Before standardized rulers, people needed practical ways to estimate distance.

They had their:

finger

hand

span

foot

arm

elbow

These simple references became formal units in different civilizations.

Modern measurement has made them far more precise, but the ancient idea remains familiar.

We still talk about feet, hands and spans.

Try It Yourself

Measure five things:

Your height

Your arm span

Your foot

Your forearm

Your handspan

Compare them.

Some relationships may surprise you.

Others may not match at all.

That is perfectly normal.

The purpose is not to prove that everyone has the same proportions. It is to discover the remarkable pattern of your own body.

Mathematics Written in Us

We usually encounter mathematics as numbers, equations and diagrams.

But mathematics also appears in living forms—in the symmetry of flowers, the branching of trees, the spiral of shells and the proportions of the human body.

Our ancestors discovered that they could measure the world using something they always carried with them.

Themselves.

And that may be the most delightful part of all.

Before we invented the measuring tape, we were the measuring tape.

Before rulers became objects, the human body was the ruler.

And even today, beneath all our technology, every one of us carries that ancient instrument with us.

Look at your hand.

You may be looking at one of humanity's oldest measuring tools.

Another marvel..

 A Masterpiece Carved In Stone

Located on the slopes of Nandi Hills in Karnataka, the Bhoga Nandeeshwara Temple is a magnificent example of India's ancient architecture and exquisite craftsmanship. 

The history of this temple complex dates back to the 9th century. The Ganga, Chola, Hoysala, and Vijayanagara dynasties contributed their architectural contributions here at different times. 

The beautiful stone Chatra (parasol) inside the temple is a special attraction for its intricate carvings. On the surface below, several layers of lotus petals, floral patterns, and bead-like geometric motifs can be seen. 

Carving such fine details on a stone without modern machines centuries ago showcases the extraordinary craftsmanship and patience of Indian artisans at that time. 

This is not just a stone canopy, but a beautiful glimpse of India's ancient artistic heritage and our rich architectural tradition.

Then the cycle returns:

Sa → Ri → Ga → Ma → Pa → Dha → Ni → Sa

The Sa of the next octave is higher than the first Sa.

What is special about them?

Unlike Western music, where the notes are generally fixed to particular pitches, in Indian music Sa is the reference note chosen according to the singer's or instrument's pitch. The other swaras are understood in relation to that Sa.

And the beautiful thing is that Sa and Pa are treated as fixed swaras, while Ri, Ga, Ma, Dha and Ni have different forms, giving rise to the rich melodic possibilities of Indian classical music.

The page  gives Alankars — patterns made by arranging these seven swaras in different combinations. Repeating such patterns is excellent for developing pitch accuracy, voice control, memory and fluency.

*The Western equivalents are only an approximate conceptual comparison, because Indian swara relationships and intonation are more nuanced than the simple Do–Re–Mi correspondence.

Bagh print. Wonder.

Bagh Print — The River That Helps Colour Cloth

Imagine discovering that the water of a river could make the colours on a piece of cloth deeper, richer and more beautiful.

Not in a modern textile laboratory.

Not in a factory.

But beside a small river in Madhya Pradesh.

This is the story of Bagh, a small town in Dhar district, and the remarkable hand-block printing tradition that bears its name.

The river flowing through the region is the Baghini. For generations, its water has been part of the finishing process that gives Bagh textiles their distinctive character. After the cloth has been prepared and printed, it is repeatedly washed in the flowing river water before being dried in the sun. The mineral qualities of the water are believed to help enhance the colours and texture of the finished fabric. 

And this is where the story becomes even more interesting.

A craft carried across regions

The Bagh printing tradition practiced today took shape in the twentieth century.

The Khatri printing community had roots in the Sindh region and later moved through Rajasthan and Madhya Pradesh. In 1962, Khatri artisans from Manawar settled in Bagh and developed the craft using the resources of their new surroundings. 

They brought with them the knowledge of hand-block printing.

Bagh gave them something equally valuable:

its water.

The combination proved extraordinary.

The colours come from nature

Bagh printing traditionally uses natural materials to create its characteristic palette.

Iron-based preparations help produce the deep black.

Alum and other natural ingredients are used in creating the red.

Vegetable materials such as harad (myrobalan) help prepare the cloth for printing, while other plant materials are used during the colouring process. 

The designs are then applied by hand with carefully carved wooden blocks.

Flower.

Leaf.

Vine.

Geometric form.

Each block must meet the previous impression with remarkable precision.

There is no digital alignment.

No automatic machine.

Only the eye, hand and experience of the craftsman.

And then comes the river

After the painstaking printing, the cloth is taken to the river.

It is washed repeatedly in the flowing water of the Baghini.

This stage is not merely ordinary washing.

The mineral characteristics of the river water interact with the materials used in the printing process and contribute to the distinctive depth, clarity and finish for which Bagh textiles are known. 

The cloth is then dried in the sun.

River water.

Sunlight.

Natural materials.

Human hands.

Together they produce something extraordinarily beautiful.

A lesson hidden in a river

Perhaps the most beautiful part of this story is that the artisans did not need to conquer nature.

They learned from it.

They observed their surroundings carefully enough to discover that the local water possessed qualities particularly suited to their craft.

That knowledge became part of a tradition.

And the tradition survived because people continued to practise it.

Today, Bagh Prints of Madhya Pradesh has official Geographical Indication status, recognizing its special connection with its place of origin. 

A piece of Bagh print is therefore more than printed cloth.

It carries the memory of a community, the skill of generations of craftsmen, the chemistry of natural materials — and, quite literally, the character of a river.

Nature did not merely provide the water.

It became part of the craft.

In darkness yet lights up still.

Ajanta — The Paintings Created in Darkness

Imagine entering a cave carved deep into a mountain.

There are no electric lights.

No windows in the modern sense.

No bright studio lamps illuminating the walls.

Only the faint light entering from the cave entrance—and the gentle, uncertain flame of an oil lamp.

And yet, on the walls and ceilings around you, there are faces, animals, flowers, royal processions, musicians, dancers, princes, princesses and scenes from the life of the Buddha, painted with astonishing delicacy.

This is Ajanta.

And perhaps one of the most remarkable facts about the Ajanta paintings is not simply what the artists painted, but where and how they painted them.

A World Inside a Mountain

The Ajanta Caves in Maharashtra were excavated into a horseshoe-shaped cliff overlooking the Waghora River.

The caves were created over several centuries, with the greatest flowering of painting and sculpture taking place roughly between the 2nd century BCE and the 5th–6th centuries CE.

Inside, the caves could be remarkably dark.

The artists therefore faced a problem that modern painters never have to think about:

How do you paint when there is almost no light?

They could not simply switch on a lamp.

They had to create their own light.

The Little Flame

Oil lamps were probably among the most important sources of illumination available to the artists.

A small flame does not produce much light by modern standards. It flickers, moves with the air and illuminates only a limited area.

Yet an artist accustomed to such conditions could work remarkably close to the wall, concentrating on a small section at a time.

There are also indications of arrangements for holding lamps within the caves.

The working environment must have been very different from the brightly lit studios we know today.

Perhaps the artist sat or stood close to the wall, with an assistant tending the lamp.

The flame illuminated the section being painted.

A few feet away, everything disappeared again into darkness.

But There Was Some Daylight

Ajanta was not completely sealed from natural light.

The cave entrances admitted daylight, and the architecture of some caves allowed light to penetrate inside.

The problem was that the deeper portions of the caves could remain very dim.

The artists may therefore have used reflected light as well as lamps, directing whatever available daylight they could toward the working surface.

Exactly how every painting was illuminated is not known.

And that uncertainty makes the achievement even more intriguing.

We know the result.

We can only partly reconstruct the working conditions that produced it.

First, the Wall Had to Be Prepared

The paintings were not simply painted directly onto bare rock.

The rough rock surface was prepared with layers of plaster made from materials such as clay, sand and other organic and mineral substances.

The surface was then made sufficiently smooth for painting.

The artists could create an even background before beginning their designs.

On this prepared surface they drew their compositions and gradually built up the figures and colours.

This was a highly skilled process.

The paintings we see today may look effortless.

They were not.

Colours From the Earth

The Ajanta artists had no modern tubes of paint.

Their palette came largely from the natural world.

Mineral and earth pigments provided colours such as red, yellow, white, green and black.

Some of the blue pigment used at Ajanta is associated with lapis lazuli, a precious mineral that had to travel a considerable distance to reach India.

The artists knew how to prepare these materials, mix them and apply them to the prepared surface.

Their palette may have been limited compared with that of a modern painter.

But within that limitation they created remarkable variety.

A face could appear gentle.

A jewel could seem to shine.

A flower could appear delicate.

A garment could suggest movement.

And Then There Were the Brushes

Think of the precision required.

The famous Ajanta paintings contain extraordinarily fine lines.

An eyebrow.

The curve of an eye.

Individual ornaments.

The fingers of a hand.

The folds of clothing.

The details of jewellery.

All had to be created with tools that were far simpler than those available today.

The artists probably used brushes made from animal hair or other natural fibres.

There were no electric lifts, no scaffolding systems like those available to modern conservation teams, and certainly no photographic projection to guide them.

Yet their compositions remain remarkably assured.

Painting a Ceiling in a Cave

Perhaps the most astonishing achievement is the decoration of the ceilings.

Look upward in some of the caves and you encounter patterns, flowers, animals, geometric designs and elaborate decorative compositions.

Now imagine painting them from below.

The artist would have needed some form of temporary platform or scaffolding.

The light would have been poor.

The surface would have been overhead.

The neck and arms would tire.

The composition had to be planned.

And yet the ceiling becomes part of the artistic experience.

It is not merely a roof.

It is another world.

They Were Not Just Painting Pictures

Ajanta is often described as a treasure-house of Buddhist art.

But the paintings are much more than illustrations.

They show an entire civilisation.

We see kings and queens.

Palaces and forests.

Musicians and dancers.

Merchants and travellers.

Animals and birds.

Jewellery and textiles.

Architecture and everyday life.

Expressions of affection, sorrow, compassion, dignity and devotion.

The artist was not merely recording a religious story.

The artist was observing human beings.

That is one reason the paintings continue to speak to us.

The Eyes of Ajanta

Perhaps nothing is more famous than the faces.

The eyes are especially expressive.

Some figures appear to look inward.

Others seem to be listening.

Some faces convey compassion.

Some suggest sadness.

Others possess an extraordinary serenity.

These were painted more than a thousand years ago, yet they do not feel like distant archaeological objects.

They feel human.

That is the great mystery of art.

Stone may survive.

Pigment may survive.

But what truly survives is feeling.

Darkness Could Also Protect the Paintings

The darkness that made painting difficult also helped preserve the paintings from direct sunlight.

Sunlight contains ultraviolet radiation that can damage pigments and organic materials over long periods.

Inside the caves, the paintings were sheltered from intense exposure.

But their survival has not been easy.

Moisture, changes in temperature and humidity, dust, human contact, smoke and the passage of centuries have all affected them.

What remains today is therefore precious.

And conservation requires enormous care.

Imagine the Artist

We know the names of very few of the individual artists.

They did not sign their works in the manner of modern painters.

We therefore stand before masterpieces whose creators have largely disappeared into history.

Perhaps that is strangely beautiful.

The artist is anonymous.

The painting remains.

The hand has vanished.

The vision remains.

The lamp that once illuminated the wall has long gone out.

But the image it helped create is still before us.

A Painting Made in Darkness

There is something almost symbolic about Ajanta.

The artists entered darkness and created colour.

They worked with tiny flames and created worlds.

They had limited materials and created extraordinary richness.

They worked with simple tools and achieved astonishing delicacy.

They painted stories of compassion, wisdom and human transformation—and their own work became a story of human transformation as well.

A dark cave became a gallery.

A rough mountain became a canvas.

Earth became colour.

A small flame became enough light.

And human imagination did the rest.

Ajanta's Quiet Message

Today we live surrounded by light.

We can illuminate an entire building with the touch of a switch.

We have powerful lamps, cameras, digital screens and sophisticated artistic tools.

Yet Ajanta quietly reminds us that great creativity does not always require perfect conditions.

Sometimes the human mind begins with very little.

A dark cave.

A small lamp.

A few colours.

A simple brush.

And an idea.

More than a thousand years later, we are still standing before what that idea became.

They painted in darkness—

and left behind a light that has not gone out.

What an idea.

 “interesting things happening in the world” 

The Human Library — Where People Become the Books

Imagine walking into a library.

There are no shelves filled with novels.

No history books.

No biographies.

Instead, there are people.

You look at a catalogue and choose a “book” whose story interests you. A librarian introduces you. You sit together, perhaps in a garden, and for about thirty minutes you can ask questions and listen to the person's experiences.

You are not borrowing a book.

You are borrowing a human being's story.

This is the remarkable idea behind the Human Library, an initiative created in Copenhagen in 2000 by Danish activist Ronni Abergel, his brother Dany and colleagues Asma Mouna and Christoffer Erichsen. The first event was held at the Roskilde Festival and offered more than fifty different “titles.” More than a thousand people came to read them. 

What is a Human Book?

A Human Book is a volunteer with a particular life experience that people may have misconceptions about.

The “titles” can therefore sound very unusual:

ADHD.

Autism.

Former Sex Addict.

Greenlander.

Lonely.

Early Retired.

Police Officer.

Bullying Survivor.

These are not labels intended to define a person.

They are invitations to understand a life that may be unfamiliar to us.

The idea is simple.

We often form opinions about people before we know anything about them. We see an occupation, an appearance, a disability, a social background or some other characteristic and unconsciously fill in the rest of the story.

But a real conversation can disturb those assumptions.

The Human Library describes its purpose as creating a space where difficult or taboo subjects can be discussed openly and where people can challenge their own prejudices. 

How does the borrowing work?

It is remarkably similar to an ordinary library.

A visitor approaches the librarian and looks at the available “books.” After choosing a topic, the librarian introduces the reader to the appropriate Human Book.

Then the two sit down and talk.

The conversation can last up to thirty minutes. Questions about the subject are welcomed, although, naturally, the Human Book does not have to answer something they do not wish to discuss. 

There are rules to make the conversation respectful and safe.

And there is a charming library rule:

You have to return the book in the same condition in which you borrowed it!

Of course, that is partly a joke. But behind it is a serious idea: the person sitting opposite you is not an object of curiosity. They are a human being.

The Reading Garden

Copenhagen eventually created a permanent home for the Human Library.

The Reading Garden opened in 2020 at Union in Nørrebro, giving people a physical place where they could meet these extraordinary “books.” Visitors could simply walk in, choose from the available subjects and have a conversation in the garden. 

Over its years of operation, thousands of people visited.

The garden eventually closed in October 2025 because the organisation could no longer sustain the cost of maintaining it, but the larger Human Library movement continues in many countries. The organisation says it now operates across six continents and in more than 80 countries. 

Perhaps the greatest books are people

There is something profound about this idea.

A printed biography tells us what happened to someone.

A Human Book can tell us:

What did it feel like?

What were you afraid of?

What did people misunderstand about you?

What do you wish others knew?

What changed you?

What would you like someone who has never experienced this to understand?

These are questions that no ordinary book can answer in quite the same way.

And perhaps the most interesting part is that the reader also becomes a little different.

We enter the conversation thinking we know something.

We leave knowing that we knew much less than we thought.

If you could borrow one Human Book...

This is the question I would love to put to readers.

Would you choose a scientist and ask what discovery changed the way they see the world?

A mountaineer and ask what it feels like to stand above the clouds?

A person who has lived through extraordinary hardship and ask what kept them going?

A monk or spiritual teacher and ask what really happens when the mind becomes quiet?

An astronaut and ask what Earth looks like when seen from space?

An artist and ask where inspiration comes from?

Or perhaps someone whose life is completely unlike your own?

Who would you borrow for thirty minutes?

And perhaps that is the most beautiful lesson of the Human Library:

Every person is carrying a book inside them.

Some books are filled with joy.

Some with suffering.

Some with courage.

Some with mistakes.

Some with wisdom.

And many of them have never been opened.

All we need sometimes is the humility to sit down and read.

Stand still and look stupid.

My son's visit now to Vienna reminded me of her.

Hedy Lamarr — The Hollywood Star Who Helped Shape the Wireless World

History occasionally presents us with individuals who seem to belong to more than one world. Some shine in art, some in science, some in public life. Rarely does one person stand brilliantly in all these realms at once.

Such a person was Hedy Lamarr.

Celebrated by Hollywood as one of its great beauties, admired by audiences across the world, and later recognized for an important contribution to communications technology, Hedy Lamarr lived a life that challenges many of our assumptions about talent, intelligence and human potential.

She was not merely an actress who happened to invent something.

Nor was she a scientist who became famous through cinema.

Remarkably, she was both.

From Vienna to Hollywood

Hedy Lamarr was born Hedwig Eva Maria Kiesler on November 9, 1914, in Vienna, Austria.

Even as a child, she was intensely curious about how things worked. Her father encouraged her inquisitive nature, explaining machines and mechanisms to her during their walks.

Yet destiny first opened the doors of cinema, not science.

She appeared in European films while still young and attracted international attention after the 1933 film Ecstasy. She later left Europe and travelled to the United States, where film producer Louis B. Mayer brought her into Hollywood.

There she received the name by which the world would know her:

Hedy Lamarr.

Hollywood soon embraced her as a glamorous star. She appeared in films including Algiers, Boom Town, White Cargo and, most famously, Samson and Delilah.

Her beauty became legendary.

But behind the screen image was a woman who loved ideas, machines and invention.

The Inventor Behind the Movie Star

Between films and studio commitments, Lamarr spent time thinking about inventions and practical problems.

She was not formally trained as an engineer, but she possessed something equally valuable to an inventor: curiosity.

She enjoyed taking things apart, understanding mechanisms and imagining how they might be improved.

During the Second World War, her thoughts turned towards helping the Allied war effort.

She had watched events in Europe with deep concern and wanted to contribute in a meaningful way.

Her contribution would come not from a film studio, but from an unexpected partnership.

A Wartime Idea

Lamarr worked with George Antheil, an American avant-garde composer and experimental thinker.

Their problem concerned the radio control of torpedoes.

A remotely guided torpedo could potentially be disrupted if an enemy detected and jammed the radio frequency being used to control it.

So they imagined something different.

Instead of keeping the communication signal on one frequency, the transmitter and receiver could rapidly change frequencies together, following a synchronized pattern.

An enemy trying to interfere with the signal would have a much harder time blocking it.

The idea became known as frequency hopping.

Antheil's experience with synchronized player pianos helped inspire the mechanism they imagined for coordinating the changing frequencies.

In 1942, Lamarr and Antheil were granted a United States patent for their frequency-hopping communication system.

It was an extraordinary idea for its time.

Too Early for Its Era

The invention did not immediately become the military breakthrough they had hoped for.

The technology required to implement their system effectively was not yet readily available, and the invention received little practical attention during the war.

But important ideas do not necessarily disappear simply because their moment has not yet arrived.

The principles behind spread-spectrum and frequency-hopping communication were later developed and used in various communications systems.

Over time, such techniques became important in military communications and later in civilian wireless technologies.

Modern wireless systems are enormously more sophisticated than Lamarr and Antheil's 1940s design, and it would be inaccurate to say that Lamarr directly invented Wi-Fi, Bluetooth or GPS.

But her pioneering work forms part of the fascinating history of spread-spectrum communication, principles that became important to later generations of wireless technology.

That makes her story remarkable enough without exaggerating it.

Beauty Became a Distraction

Perhaps the most fascinating part of Lamarr's story is not the patent itself, but the way people perceived her.

She was so extraordinarily beautiful that the world found it easy to stop looking beyond her face.

Her appearance became her public identity.

Her intelligence remained largely hidden behind it.

She once quipped:

“Any girl can be glamorous. All you have to do is stand still and look stupid.”

The remark is funny.

But there is something deeper beneath the humour.

Lamarr understood that people often make assumptions about others from what they see first.

A beautiful woman could be treated as decoration.

A film star could be assumed to have little interest in science.

Yet the same woman could sit down and think seriously about radio communication, synchronization and engineering.

Her life quietly challenged those assumptions.

Recognition Came Slowly

For many years, Lamarr's contribution to technology was not widely known.

Her Hollywood career remained far more famous than her invention.

Only later did greater attention come to her work in communications.

She eventually received recognition from the technological community, including induction into the National Inventors Hall of Fame in 2014, more than a decade after her death.

By then, the world had changed enormously.

Wireless communication had become an essential part of modern life.

The idea that a Hollywood actress had helped pioneer an important communications concept seemed almost unbelievable.

But it was true.

A Mind Without a Label

Hedy Lamarr's story invites us to question the categories into which we place people.

Can an artist also be an inventor?

Can a performer think like an engineer?

Can beauty and intellect exist together without one cancelling out the other?

Of course they can.

Perhaps the real lesson is even simpler.

Never mistake the visible part of a person for the whole person.

We see someone's profession, appearance, age or social role and unconsciously construct a complete picture of them.

But every human being may contain abilities that the world has never noticed.

Hedy Lamarr was a movie star.

She was also an inventor.

She was fascinated by technology at a time when few people expected a Hollywood actress to be interested in engineering.

Her story reminds us that creativity does not respect boundaries.

The same mind can imagine a character on a cinema screen and a mechanism in a communications system.

The same person can be captivated by art and fascinated by machines.

Brilliance does not always announce itself in the form we expect.

Sometimes it arrives in a laboratory coat.

Sometimes it arrives carrying a musical score.

And sometimes, remarkably, it walks onto a Hollywood film set.
