Snowflake 871 Many people mistake snowflakes for being two-dimension objects. While the normally grow along a flat plane, they are anything but flat and featureless. Let’s explore the features we see here, starting with the center hexagonal gem. You’ll be thrilled to know that same physics that created this, also creates branches and other snowflake features! The basic rule: whatever sticks out the farthest, grows the fastest. This makes sense, right? More access to water vapour the further out from the center of a snowflake you are. The inverse is also true – whatever is furthest away from the access to water vapour will grow the slowest. Take into account the three-dimension nature of a snowflake as a hexagon prism, and you might be able to imagine how cavities begin to form in the inner areas of each prism facet grows slower than the outer top, bottom, left and right edges. These cavities can start in the center of the facet and slowly grow to the corners. In some instances they can actually divide the entire snowflake in two! And that’s exactly what happened in the center. The bottom of the two halves must have been slightly thinner, and it grew a little faster outward as a result (the available building blocks have less volume to fill to extend the growth further outward). Boom, branches! Leaving the original shape at the time of separation to stay the same, maybe growing slightly thicker in time. If growth is slow, snowflakes tend to thicken up. We can see a perfect example of this about mid-way up each branch, looking faintly like the letter M, but with the center column higher than sides. Imagine this shape as the outer branch of a snowflake, dialing back the clock. This edge grew thicker, so thick that it towered over the rest of the snowflake. If you add more humidity, the crystal would again grow outward… but because of this extra tall outer ridge, it began growing out from the top and bottom as separate planes. #snow#snowflake#science
One of the most memorable trips of my life so far ❄️ walking on frozen Lake Baikal, Siberia. It’s one of those places on Earth I never thought I’d have the chance to visit one day. But I did and I loved it, despite the cold 🥶 check out the third video, would you try that? 😱 Share this video with your travel buddy! #baikal#siberia#russia#winter#cold#ice#lake#earthpix#wonderful_places#voyaged#travel#travelgram#travelblogger#traveltheworld#cold#athensvoice#greek#9gag#ladbible#wanderlust#wanderer#earthfocus#travellingthroughtheworld#earthofficial#earthporn#earth_deluxe
Being vulnerable doesn’t mean you are weak. When you’re voluntarily vulnerable you show the world you’re ready for it. You’re aware of what it can and will do you but you don’t care, because you possess a strength and confidence that comes with being vulnerable on purpose.
