The Exquisite Geometry of Falling Stars: Exploring the Science of Snowflakes

Snowflakes. Those tiny, intricate specks of frozen water silently painting the winter landscape hold a unique magic. But have you ever thought about how these delicate masterpieces came to be? Let’s journey into the science behind snowflakes and marvel at their extraordinary beauty.

How Snowflakes Are Born

A snowflake’s journey begins within a cloud, high in the atmosphere, where temperatures are far below freezing. Water vapor in the air condenses onto microscopic particles like dust or pollen, creating a tiny ice crystal—a miniature seed for a snowflake. As it tumbles and twirls within the cloud, more water vapor freezes onto the crystal.

The Magic of Six Sides

Interestingly, when they freeze, water molecules naturally arrange themselves into a hexagonal (six-sided) pattern. This is why the basic snowflake always has six arms or branches. But that’s just the beginning! The exact shape of a snowflake depends on the ever-changing conditions it encounters on its descent. Factors like temperature and humidity make every crystal unique.

Types of Snowflakes

Stellar Dendrites: These classic, star-shaped snowflakes are the ones you see in picture books – intricate arms radiating from a center point.

Needles: Long, thin, column-like crystals that form in specific temperature zones.

Plates: Flat and wide snowflakes that are often hexagonal.

Capped Columns: A hybrid form, looking like columns with plates on each end.

Why No Two Are Alike

There’s an old saying that no two snowflakes are the same. While it’s almost impossible to prove scientifically, the logic is sound. Think about how many tiny changes affect the snowflake’s path through the cloud. Each subtle shift in temperature or humidity leaves its mark on its structure, ultimately creating a one-of-a-kind crystal.

More than Just Pretty

Snowflakes aren’t just a beautiful sight. They play a crucial role in our ecosystem. Snow cover provides insulation for the ground, protecting plants and animals from harsh winter temperatures. In spring, the snow melts, replenishing rivers, lakes, and reservoirs with essential water.

Appreciating Winter’s Jewels

Next time it snows, pause and appreciate the dance of these frozen wonders from the sky. Get a magnifying glass and look at a single snowflake closely if you can. You’ll see just how complex and unique nature’s artistry can be.

   Dendrite; His wings are like crystallized dendrite, Lucifer notices.

   Intricate patterns of iridescent gold branches engraved in each fulgent feather of his. Rays of daylight that dare reflect off the Messenger’s butterscotch wings are ardently absorbed to preserve his internal light—He burns far brighter than any star could begin to comprehend.

   Lucifer can feel his warmth when he allopreens Gabriel’s dendrite-etched feathers. The thriving fledgling squirms uncomfortably under his working hands, his budding golden feathers twitching with each gentle pluck. His petite form leans away from Lucifer’s algid touch, and he whines with a callow pout when Lucifer prudently guides him back. Lucifer attempts to soothe his baby brother, amicable words of a story falling from his polar lips to allay Gabriel’s discomfort; Gabriel always loved his stories.

   The gold expands as he develops. Complex veins of sunlight-drenched sheen contour the coverts of his pinions. The shinier they get, the brighter he burns and the more pleasant light he intakes. Gabriel emits brilliant luminescence like no other, and his sun-kissed wings like dendrite are proof.

   Lucifer combs through gold with every softly recited word of a tale. Gabriel has grown to melt into the Morningstar’s wintry touch, listening attentively to the plot of his elder brother’s story. He is eagerly expectant; His big brother always comes to him with newer, longer, better anecdotes during preening season. Gabriel adores every one of them, though when he feels Lucifer culling the last of his unkempt and grimed feathers, he pleads with full, star-struck sky eyes to hear the lullaby that first lulled him to sleep, long ago. Lucifer teases him with fondness in his irises, but he gives in—He always does. It’s hard to say no to Gabriel when he looks that jubilant.

   “... dream on, dear little child…”

   Gabriel has already complied to the lullaby’s verses by the time Lucifer adeptly tweaks the last sliver of gold. The Morningstar’s waning notes fade out, though his boreal fingers still find themselves in between honey, dendrite-embedded feathers. Gabriel snores like a little beast, and Lucifer can’t help but grin at him as he gingerly caresses his slumbering brother’s effulgent wings.

   The luster of his gold is brightest against the pristine cream of misted clouds. By the time Lucifer teaches Gabriel to fly, he’s become a beacon in the night. Lucifer’s frosted fingers tag one of his younger brother’s radiant wings, sniggering as he calls out “you’re it!” and soars swiftly in the other direction of Heaven’s lilac skies. As much as he tries through his giggles, Gabriel can’t keep up, and they both know it.

   He’s growing too fast. At times, Lucifer reminisces on the distant era he was able to hold Gabriel in his arms. His dendrite-pattern had hardly blossomed then, and Gabriel’s gold hadn’t shimmered as bold. As he looks at his younger brother now, he sees curious divinity. Gabriel’s getting old enough to where Lucifer can’t shield him from danger, and it makes the elder angel anxious.

   The snow of the Morningstar’s fingers drag further, deeper into gold. Gabriel’s wings are evolving, the golden bliss of his spirited light washing vividly over Heaven. The Messenger no longer leans in, nor away from Lucifer’s preening; He simply hums, swaying in rhythm with the breaths of Lucifer's story. No matter how old he gets, he always loves to listen to his big brother’s voice. When Lucifer is nearly finished grooming auric feathers, he happily anticipates Gabriel to plead with him to sing their lullaby. Instead, Gabriel turns to him, and his golden light seeps through his wide smile, a trickle of celestial sun through pearly teeth.

   "Luci, can I pretty please do yours?"

   Lucifer is taken aback. Gabriel has never offered to preen his feathers; Lucifer's wings hadn't been preened since Michael had taken up his part of Heaven's responsibilities—It had been a long time. Lucifer’s matured wings flex automatically in thrill at the mention of grooming. Gabriel acknowledges it, and he brightens, if possible. His little brother is giving him that look, one of so much inspired euphoria with such a rush of nostalgic innocence that he looks no different from the very first time Lucifer preened his teensy, yet complex feathers.

   Lucifer can’t refuse. 

   His wings of vermillion are far larger, though far more disheveled than Gabriel’s have ever been; The young Messenger has always had Lucifer to care for him. Gabriel’s clement hands are profoundly gentle, like refreshing spring rain drizzled on feverish skin or a tenderhearted baby dove nuzzling gratefully against its mother. Even at viscid spots where his vermillion adheres in thickly bedraggled clumps as a result from neglect, Gabriel’s touch remains serene and delicate. Lucifer feels more tranquil than he has in centuries—It’s as if he’s mindlessly drifting amongst endless indigo seas of winding galaxies and Gabriel is sweetly guiding him by the hand through the silver of stars. Lucifer now understands why Gabriel loves Heaven’s preening season.

   A faint ghost of a mellifluous melody draws him from his wafting reverie. Gabriel is humming, a saccharine purr carrying a familiar harmony; It’s their lullaby. Lucifer picks up on the part his baby brother is humming, and he nimbly sings along. He watches intently with a splitting simper when their sitting shadows in front of him swell as Gabriel’s golden light brightens merrily at the pleasant sound.

   “... in the sky, stars are still fading away…”

   Gabriel’s effulgence is rapidly dawning to be more blinding than any entity in existence. His stellar golden feathers branch out further and his daedal dendrite details seem to crystallize in a more radiant fashion. Lucifer genially revels in his bright brilliance everytime they unite. Though, it’s far from the only thing that’s improving in Gabriel; He’s much quicker than before. Lucifer has to exert all of his energy to keep ahead when briskly gliding away from his little brother after he tags his butter-flushed wings. He deliberately assumes that Gabriel will inherit his Heavenly duties soon, with his speed approaching the potential Father saw when he named him as Heaven's Messenger.

   Gabriel isn’t the only one who’s changing.

   Lucifer is altering—morphing—wavering. The Mark of Cain is an irritant upon his ivory skin, his grace, his mind. He’s growing colder, and he feels the need to be enigmatic. Father is never wrong, because Father is absolute. It’s firmly ingrained in his mind, and it’s been that way since he was a fledgling. Lucifer repeats it to himself as he observes Lilith, the first woman, refuse subservience to her created equal, Adam. He watches silently when she leaves the perfect haven Father had meticulously created for her, and he watches in bemusement as a flock of his determined siblings attempt to forcibly return her to Eden. She is resilient, and Adam is egotistical and very flawed; Lucifer desperately tries to comprehend why his Father, instead of establishing that they are equals, creates Adam a new partner and banishes Lilith from ever returning to Eden.

   Father is wrong. When the belief dawns on him, Lucifer has an epiphany—a twisted thought follows. The Mark of Cain sears like it never has before; A scorching white fire that engulfs his entire being, scalding the abundance of all his infinite eyes and fiercely igniting his vermillion wings in grandeur flames. Despite the famished embers from within, he feels frozen and trapped under a bulky sheet of ice, breathlessly viewing his life continue without him as he drowns in desolate, boreal seas. 

   Lucifer has unequivocally changed; He is different. Gabriel is the first to notice. 

   Preening season has arrived. Lucifer is much colder, and the raw bite of his frost elicits a vicious shiver when his fingers pluck gold feathers. His cautiousness is replaced by dissociation, the younger angel is wincing. Lucifer feels distant, and Gabriel thinks he is lightyears from his brother despite him being mere inches away. 

   Lucifer abstractly traces dendrite when he’s nearing the final unkempt clot of feathers, absentmindedly humming a familiar tune. This time, Gabriel says nothing. His scintillant wings tense up at bitter ice fingertips picking at his golden light.

   “... down here, a dying dove crawls…”

   The lyrics have changed. Lucifer feels numb; Gabriel feels scared.

   It’s the last expression Lucifer sees from Gabriel, and it’s the last thing he remembers when he returns from Eden. He is abruptly a liar, he is a liar without deceiving. He is no longer the Morningstar. He is the Serpent.

   Michael’s rigid voice is echoing, lightning is cracking, angels are wailing. His Father's—his Father who is wrong—light feels cold. Lucifer can’t hear, feel any of it. The thrum of a familiar lullaby is beating in his ears. All harshly fades away when he promptly perceives that the burning white fire that had smouldered within him is suddenly reality, and it is reflected on vermillion wings. He is physically falling, a lightheadedness clouding his consciousness, and when he forces open his forlorn eyes against the whizzing wind, he sees smoke. Lucifer screams.

   Vermillion is ablaze. He is frightfully alone as he fleetly plunges into an unknown abyss, an alien place that is farther from home than he can begin to comprehend. A despairing attempt to frantically flap his wings ensues, but they only twitch. He tries again in a panic, and the insatiable white flames tease him with a hungry smirk. The Serpent relents in his feeble attempts to salvage his wings, squeezing his eyes shut again and dreadfully awaiting impact.

   Lucifer can’t help but wonder if gold would be more successful.

   He is going to be the dove. He is the dove.

𓏧༻🕊️༺𓏧

   Gabriel is grown; It’s Lucifer’s first observation.

   A foolish little part of him expected him to never age, forever remaining the same sweetly innocent fledgling that Lucifer once held lovingly in his arms. Forever lasting the same playful angel that struggled to tag him back. Forever retaining the same ambitious persistence to hear his big brother’s stories. Forever seeping golden washes of sunlight through his toothy beams, harboring the brightest light in existence within his being.

   This time, it's Gabriel who has changed; He has dimmed significantly. Lucifer misses his light.

   Lucifer maps the faint outline of his brother’s golden wings with his eyes, burnishing cracks through the universe’s perceptibility to accommodate him. Lucifer had frequently thought about the refined softness of the gold between his fingers when he was imprisoned, and he’d pondered about who would care for them while he was away. Who would pluck his fledgling’s feathers during preening season, who would tell him stories and lull him to sleep? In this moment, Lucifer can see that nobody has; Gabriel’s gold is matted and besmirched.

   Gabriel was alone, just as he had been.

   He wields a blade, Lucifer acknowledges. Gabriel intends to kill him, despite the blatantly obvious fear in his true form's numerous uncertain azure eyes. Lucifer can sense it from miles away. It’s the same look he’d worn when Lucifer had last allo-preened his brother’s butterscotch wings—The look he’d bore when Lucifer sang the last notes of their lullaby, one he’d twisted to mirror his emotions at the time.

   Gabriel’s hands slightly tremble as he raises his blade behind his brother, reluctantly creeping forward. Lucifer’s tarred wings twitch like they did when he fell, and he imperceptibly rubs at the deity blood stuck between his fingertips in anticipation.

   He doesn’t want to be the dove again.

   He turns. The fear in Gabriel’s irises is more decipherable, so visible that Lucifer can nearly catch up on all the millennia he’d missed in this very moment. Lucifer is catatonically speaking, though he barely understands it himself. The blade is resting like bait against Gabriel’s skin, a tense pressure that Lucifer can almost feel against his own chest. 

   Lucifer wants to see his baby brother’s light again.

   He does. The blade is abruptly buried in Gabriel’s being, and his brother’s fear is gone. Intense radiance of pure, euphoric sunlight envelops Lucifer as Heaven’s Messenger’s last flicker of light shines, just as he was meant to do. Brilliant light is blinding; Gabriel’s is alluring. Lucifer is warm for the first time since his wings were searing, and he thinks he hears the memory of Gabriel humming their lullaby. Gabriel feels like home, he feels like the fledgling he once knew. Lucifer feels like himself again. He sees gold.

   It’s over as quick as it began.

   Lucifer is alone again. Though, now, he stands over the fledgling he’d raised, the fledgling he cherished, the fledgling he loved—His fledgling. His wings are no longer gold, no longer luminous. They are gloomy, blackened shadows against the hardwood floor. Lucifer’s stomach twists in knots, spurts of swelling emotions he hadn’t felt in years swirling sourly in his being, and he drops Gabriel’s blade. 

   Gold is black. Gabriel is gone.

   That same foolish part of him expected there to be nothing but raw sunshine where Gabriel now lies, for his vessel to evaporate and his grace to rejoin the bright star he was created from. Instead, he sees vermillion; a thin stream of it dripping in blots against the floor.

   Lucifer can’t help but notice the way his blood oozes in a familiar dendrite pattern. Dendrite; Gabriel, a grand cluster of light so brilliant, his gold wings streaked with crystallized branches of it.

   The Serpent leaves, the whispers of a certain tune in his head. He hopes it can conceal the shrieking sound of his own convoluted thoughts.

   He doesn’t want to be the dove again. Gabriel takes his place.

Did I mention how blown away I am at the support you all have shown me with the release of my last jewelry collection? 💞 I can't believe there are only 5 necklaces left. And here they are!

The first is a stunning rainbow moonstone with oak leaves. The flash of the moonstone is unlike any I've come across before. The leaves were collected by me during one of my hikes.

The second is a coffin-cut deep blue labradorite with three long laser quartz crystals. The coffin cut pieces always remind me of a song called Crypt that I like very much by the band Unleash the Archers. One of my favorites.

The third is a long polished clear quartz wand adorned with a fiery Mexican opal. This combination always reminds me of the brutal contrast of mother nature and how she gives and takes away. Like fire and ice.

The fourth is a gorgeous warrior. I simply named this pendant Shield-Maiden. She reminds me of both my strength and compassion during difficult times, and that I need not sacrifice one trait for the other.

And the last pendant is a golden healer quartz with mossy dendrite inclusions, and three alder cones that I collected on a hike. It is truly the embodiment of the lovely alpine habitat I call home.

❄️What is a Stellar Dendrite?❄️

Snow science is something that is new to me. As someone who has lived in hot climates most of my life, I cant say I've spent enough time around snow to perform scientific studies on it.

This week however, I actually got to explore snow and learned quite a lot! We spent the day on top of Brundage Mountain digging snow pits to determine the structure, strength, and history of this year's snowpack (something I'll detail later) but we also were able to examine snow through a scope. It was there I really examined stellar dendrites for the first time! 

Stellar Dendrites are what we typically picture when we think of snowflakes. They are hexagonal growths of ice crystals on tiny bits of dust, pollen, and other airborne material. These materials have water vapor deposited on them as the air cools and they grow into the fascinating structures we call snowflakes. What's even cooler is that the humidity and temperature can affect and change the formation shape of these snowflakes.

This is just the first stage of the incredible metamorphosis that snow undergoes each time it falls. Would you like to learn more about snow and how it forms and transforms throughout its life cycle? Find my other work here!

Pre-Production - Inspiration

Analysis of 3 magnified images

Macro photography is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size.

Microphotographs are photographs shrunk to microscopic scale. Microphotography is the art of making such images. Applications of microphotography include espionage such as in the Hollow Nickel Case, where they are known as microfilm.

Female Maevia inclemens Jumping Spider – Thomas Shahan

VISUAL - This photograph presents an extreme use of different textures, evident from the very fine tufts or fur and the fuzzy surface of the arachnid. The strongest focal point of this image is, without a doubt, the two large central eyes. These eyes are deep and within them the viewer can see a swirl of specular and diffused reflections and a blend of colours. The greens and reds of the eyes compliment their sheer blackness and create a more interesting focal point, in my opinion. 

TECHNICAL - This photograph was taken using a Macro Lens which greatly increases the quality and clarity of miniature objects/subjects. The photo was taken using a wide aperture as the face of the creature is in focus but it's body is not. An ISO of roughly 100, evident from the clarity of the photograph. Controlled studio lighting was used to take this image. Correctly exposed. 

CONTEXTUAL - A magnified photograph of a baby spider which demonstrates the power of macro photography. 

CONCEPTUAL - Thomas Shahan is a Macro photographer who specialises in photographing insects under an extremely magnified lens.  

stellar dendrite - Michael Peres 

VISUAL - This image displays a striking variation in shape, all of which seen within this small object. The pale/pastel like colours all fade in and merge with one another very nicely. This creates a pleasant feel to the photograph. The photographer has placed the snowflake dead centre of the photograph, which in this case is actually an effective decision. This is effective as our eyes are drawn to the centre of the snowflake, then led throughout the intricate details of the snowflake, almost like leading lines. 

TECHNICAL - “This ice crystal was approximately 1 mm in size. The picture was made at 2:00pm and the temperature was 14 F”. This photograph was taken using a Micro lens, evident from the nature of the subject, and the extreme way we can see all the detail. ISO I would say 100 and a small aperture to have the entire snowflake in focus. Controlled studio lighting was used here, coming from a 45 degree angle at the bottom left of the subject, evident as the light is brightest there, then slowly fades throughout the photograph. 

CONTEXTUAL - An image of a snowflake, taken under a microscopic lens. 

CONCEPTUAL - Michael Peres takes photographs of microscopic objects. He aims to allow the viewer to see an object in a whole new light. He shows us aspects of subjects that we cannot see with the naked human eye.

Flowers - Kathleen Clemons

VISUAL - This photograph displays a stunning use of colour. The reds and yellows are soft and faded yet equally powerful and visually striking. There are various layers and shades of each colour filtered throughout the photograph. To my eye, this no longer is a flower, but a magical sea of scarlet and gold. The gold bulb is not in the centre of the photograph, but instead positioned slightly to the right, offering a unique and more balanced image, allowing the petals to flow outwards and around the surrounding space of the photograph.

TECHNICAL - This photograph was taken using a macro lens, really focusing on the fine details of the flower. I would say that a slightly higher ISO was used, perhaps 400 to 600, as the image is faded and ever to subtly out of focus. Additionally, i believe a faster shutter speed was used as the photograph is slightly underexposed. Although i would say that these technical decisions all work

CONTEXTUAL - A close up shot of the inside of a flower

CONCEPTUAL - Kathleen Clemons has a series in which she uses macro and micro photography to photograph the fine beauty of mother nature

TAFAKKUR: Part 335

THE WONDER OF THE SNOWFLAKE: Part 1

Many things are beyond our limited scope of hearing and sight. However, with the development and advancement of technology, to our amazement, we are learning new things about the world we live in with each passing day. Each finding, or realization, of a fact is like a treasure of beauty revealed to us in complete perfection. These discoveries teach us mind-stunning realities about our surrounding environment and its material elements. In this article, I will discuss the wonder of the snowflake, a tiny six-sided miracle of creation that baffles scientists and people alike with its ingenious structure and awe-inspiring beauty. This magnificent piece of art is a perfect example of pure beauty and marvel.

Wilson Bentley took the first photomicrographs of a snowflake, thereby initiating extensive research on the snowflake. When he was 15 years old, his mother gave him a microscope as a gift. He began studying several things under the microscope, among them raindrops and snowflakes. Later on, he discovered how to photograph this delicate ice formation and presented it to the world. His enthusiasm for photographing snowflakes continued until his death 47 years later. Through his photomicro graph collection, we can see just what a complex and wonderful creation each snowflake is and why it has been the subject of such debate over the years.

The average snowflake is made up of 2 to 200 separate snow crystals; much larger ones can contain as many as 1,000 separate snow crystals. These snow crystals begin to form around tiny dust particles that have been carried up high into the atmosphere. When the temperature drops below freezing at these high altitudes, water vapor clings to these dust particles. Interestingly, the water vapor skips the liquid state and turns directly into ice, a process called sublimation. When the air contains enough moisture and the ice crystals accumulate, these crystal formations begin to fall as snow.

Scientists believe that there are only four different types (shapes) of these six-sided snowflakes; hexagonal plates, stellar stars, stellar and plate combinations, and spatial dendrites. Hexagonal plates are thin, solid, or partly snow crystals. This pattern is made up of a variety of ridges and hollows, as well as thick and thin ice. The stellar star pattern is the one many know as the symbol of a snowflake. It assumes this pattern because ice crystals tend to cling together in "cottony" clumps and have the corners of a star, unlike hexagonal plates.

The stellar and plate combination pattern is formed when plate and stellar star characteristics unite. The resulting flake is considered the most exquisite of all crystals. The plate pattern is in the middle, and the stellar star branches out from the plate. Finally, the dendrite, another stellar type, is identified by small crystals that branch out, fern-like, along each of its six "rays."

It is believed that the shape of the snow crystals forming these snowflakes depends on the temperature of the cloud in which it is formed. Ice crystal columns are formed in the highest clouds, which have the lowest temperatures. Dendrites and star-shaped crystals are formed in the slightly warmer middle clouds, and needle ice crystals are formed in the lower clouds. These temperature variations cause each snowflake to assume a specific shape. Different sources give slightly different temperature ranges and different explanations of a snowflake's developmental stages. This may be to the fact that scientists do not have exact knowledge of the conditions and formation of these delicate crystals, for they base their assumptions on laboratory experiments that seek to create the same weather conditions. It must be pointed out, however, that all snowflakes "created" in laboratories are always deformed and do not resemble the perfectly symmetrical flakes found in nature.

The first wonder I would like to describe is the snowflake's construction. Nuclear physicists and crystallographers are still trying to explain this complex bridgework of molecules that form the ice crystals into a snowflake. A brief explanation behind the construction mystery is that an average hexagonal-shaped crystal may contain 100 millon more water molecules. The ice crystal grows by adding more and more molecules. Its growth proceeds in a way that is both perfectly horizontal and perpendicular, thus building a broader and thicker crystal. Amazingly, this process is always carried out within the same hexagonal symmetry.

An ice crystal's framework is a marvelous example of solid geometry, for it always presents an ingenious grouping of molecular parts. Not only does the ice of a snow crystal grow perpendicularly by interlocking pyramids, but at the same time its horizontal ice particles extend themselves in overlapping hexagonal patterns.

But not all of a snowflake's beauty can be seen with the naked eye. Each crystal contains an invisible masterpiece of construction resembling an ongoing pattern that becomes smaller and smaller. Such a development is produced by the ice crystals themselves, which bond to each other and thereby increase the snowflake's size. Over a period of 15 minutes, and under the conditions necessary for sublimation, a snow crystal gradually assumes the shape of the first stage. This baby crystal is unbelievably tiny, from .008 to .009 of an inch in diameter.

The average initial crystal may appear as hexagonal plates, sector plates, various stellar forms, or as capped columns. This later shows evidence of a skeletal structure, surface design, and pattern that subtly determine the snowflake's final pattern. Later, this plain star will begin to develop either crystal twigs or fern-like plumes. As the final ice structure becomes heavy, it begins its journey to the ground.

An additional wonder is that no two snowflakes are alike! Each snowflake has a unique combination of ice crystals, which creates a unique snowflake. No two identical snowflakes have been found.

Another mystery is why each snowflake has six sides. Johannes Kepler, a physicist and mathematician, has studied this for years. In his The Six-Cornered Snowflake, he mentions some very important and thought-provoking questions and explanations. He also states that there must be an agent for such perfection and calculation, some definite reason why a snowflake's initial form invariably displays the shape of a six-cornered starlet. Why always six? If this were the result of chance, should not some of them at least have five or seven corners?

How to Draw a Snowflake Detailed

Snowflake develop when ice crystals form around a speck of dirt or other debris. As water ices up, it takes the shape of a crystal lattice, triggering snowflakes to show spectacular geometric patterns. It is said that no two flurries of snow are precisely alike, which is most likely real in the crystal's smallest details. Visit  website about the Artists!

Nevertheless, snows can be put in 8 groups and eighty subcategories based on their raw form. These consist of the needle, plate, column, prism, dendrite, as well as rime. The development called a "capped column" snow looks like the CONNECTION fighter from the Star Wars films!

Much of our expertise of the snow's shape can be credited to the work of researcher Wilson Alwyn Bently, beginning in 1885. Bently photographed hundreds of snows utilizing a microscope, or order to identify whether the same snowflakes could be found. In his photographs, he never discovered two flakes that were alike. It is estimated that the average snowfall has greater than five quintillion snows - that's 5 complied with by 18 nos.

Snow pictures are utilized to signify a variety of suggestions. In Europe and The United States And Canada, the snowflake is used to represent the Christmas season. Its white shade has caused it to become an icon of pureness. The snowflake shape additionally means cold weather, the winter, as well as winter season sporting activities. It has belonged of the emblem for the Winter season Olympics considering that 1968.

Would you like to attract your very own snowflake to make welcoming cards, decorations, or various other artwork? Welcome wintertime using this easy, detailed snow attracting tutorial. All you will certainly require is a pencil, an eraser, and also a piece of paper. In each step, you will undoubtedly find an in-depth picture accompanied by informative text. New lines attracted each action are always highlighted in blue. Some measure includes the removal of previously drawn lines, called overview lines.

Are you all set to draw sufficient snows for your school to declare it a snow day? If so, let it snow, let snow, let it snow!

How to Draw Snowflake: Action 1

1. Begin by Draw two long, right, upright lines, running parallel to each other. These lines will create the main shaft of the snow.

How to Draw Snowflake: Action 2

2. Draw an additional set of long, directly, parallel lines, crossing the very first at an angled angle. These lines develop extra arms of the snow.

How to Draw Snowflake: Step 3

3. Draw the third collection of long, right, parallel lines, going across at the same point where the other lines satisfy. Your snowflake will certainly now have six arms, all evenly spaced.

How to Draw Snowflake: Step 4

4. Draw a little hexagon in the middle of the snow, using six straight lines. The factors of the hexagon should be straightened with the arms of the snowflake.

How to Draw Snowflake: Step 5

5. Remove the overview lines from within the hexagon.

How to Draw Snowflake: Step 6

6. Draw a tiny circle to enclose completion of each arm of the snowflake.

Exactly How to Draw Snowflake: Action 7

7. On each arm of the snowflake, prolong two sets of straight, identical lines at angled angles as contrasted to the peninsula. Enclose the shape with a little, bent line on each end. The resulting figure will certainly resemble a boomerang. Repeat this process up until a form has been made use of each arm.

Pattern formation is extremely common in nature, from the dendritic growth of trees and snowflakes to the stripes of a tiger. A new paper describes how a thin layer of ice in a liquid can form labyrinthine patterns when illuminated with near-infrared light. Both the liquid and ice are maintained at a constant temperature below the melting point, but the ice absorbs the near-infrared light more effectively than the water. This means that parts of the ice that are far from the liquid warm and melt faster, creating holes that can then allow a pocket of liquid to seep in and reduce the absorption rate. The ice crystals themselves thin and expand across the surface at the expense of more holes, which eventually create larger channels that pock the ice. (Image and research credit: S.

SNOWFLAKE SNOW

The Intricate Wonders of Snowflake Snow

Snowflakes. Those tiny, delicate wonders cascade from the heavens during the winter months. Their beauty and intricacy have captured our imaginations for centuries. But have you ever stopped to think about the science behind these frosty marvels? Let’s dive into the fascinating world of snowflake formation.

How Do Snowflakes Form?

Snowflakes begin their journey as minuscule water vapor molecules floating within clouds. When temperatures drop below freezing, these water molecules cling around a particle – perhaps a speck of dust or pollen. As more water molecules attach, a unique six-sided ice crystal emerges. The exact pattern of the snowflake is dictated by the specific temperature and humidity conditions it encounters during its descent to the earth.

Why Are Snowflakes Unique?

No two snowflakes are exactly alike because of the ever-changing conditions they experience as they fall. Even the slightest fluctuation in temperature, humidity, or the path they take can influence the way water molecules attach to the crystal. This results in an infinite variety of shapes and patterns—a testament to the chaotic beauty of nature.

Types of Snowflakes

While we often imagine snowflakes as those classic, star-like shapes, they come in all sorts of forms:

Stellar Plates are the flat, six-sided snowflakes commonly seen in picture books.

Stellar Dendrites: These elaborate flakes have long branches that resemble delicate tree branches.

Needles: These are long, thin, icy crystals.

Columns and Capped Columns: These are like tiny, six-sided prisms or columns, sometimes with flat caps.

Snowflakes are More than Pretty

Beyond their visual appeal, snowflakes are essential in our hydrological cycle. The snowpack that accumulates in mountainous regions is a vital reservoir of fresh water. As the snow melts in the spring, it replenishes rivers, streams, and groundwater supplies.

The Takeaway

The next time you’re caught in a snow flurry, take a moment to appreciate the tiny wonders dancing around you. Each snowflake is a testament to the power and complexity of the natural world. They may be small, but they are a beautiful reminder of the intricate ways our planet works.

These patterns are known as fern frost, due to the resemblance of the crystal pattern to the fronds of a fern.

From Earth Science Picture of the Day; March 3, 2017:

Fernlike Dendrite Snow Crystal Photographer: John Stetson; Summary Authors: John Stetson, Jim Foster

The photo above showing fine detail in a hexagonal snow crystal was taken as the first flakes fell during a snowstorm several weeks ago in Sebago Lake, Maine. According to the Magono-Lee snow crystal classification, this is a fernlike dendrite (P1f). These large crystals are often several millimeters across and tend to fall in cold air -- forming dry (low-density) snowpacks. Taken on February 9, 2017, it's my effort to honor the legacy of Wilson Bentley (Snowflake Bentley) for the techniques he first mastered in the early part of the 20th century to capture the beauty and majesty of snowflakes.
