Snowflakes

It has been a few years since I posted about my attempts to photograph snowflakes. My recent attempt was my first in Missouri…and not a great success…more a learning experience. It was a bitterly cold day (in the single digits). It was snowing at a good rate…small flakes. I used the same materials I had in years past: red glass plate, magnifying lens clipped onto my phone, external clicker to take the pictures. I hadn’t realized the low temperature and the deck/patio being on the north (versus southwest) of the house would have on how cold I felt! The images are tantalizing but I was too cold to spend more time to get the flakes more isolated.

The better location in our Missouri house for snowflake photography will be the garage which opens to the south. It would be a good place to have my set up and be out of the wind. I might even set up an LED light underneath my plate! It’s only January; surely there will be more opportunities for snowflake photography this winter.

Gleanings of the Week Ending January 20, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Just how big can a snowflake get? It depends on what you mean by 'snowflake' - A snow crystal with six-fold symmetry is the kind of snowflake you might cut out of folded paper with scissors. But the word "snowflake" also can refer to white puffballs that drift down from the sky, which are made of many individual snow crystals that have collided and gotten entangled.

Treating tuberculosis when antibiotics no longer work - Substances that have a dual effect against tuberculosis: They make the bacteria causing the disease less pathogenic for human immune cells and boost the activity of conventional antibiotics.

Planning a city that gets people moving – Lake Wales, Florida has a plan to create a built environment that promotes mobility through walking, cycling, e-biking, or other means of transportation beside automobiles. One way to do that is through proximity—to a park, multiuse pathway, protective bike lane, or walkable destination. Another is to ensure that the environment is pleasant for walking or using a bicycle.

The qualities that are more attractive than our looks - When it comes to finding the right match agreeableness accentuates the benefits of other parts of our personalities. It really could pay to be kind after all.

Archaeologists Uncover ‘Exceptional’ Ancient Mural Near Colosseum - Crafted of shells, a special volcanic stone called pozzolana, marble, colored glass, and Egyptian tiles found in the remains of a house from more than 2,000 years ago. Its intricate designs show weapons and instruments hanging alongside ships and tridents. Archaeologists think a wealthy Roman officer commissioned it after a military success. Whoever the owner was, he may not have stayed wealthy for long. Evidence suggests that his family fell out of favor when the Roman emperor Augustus came to power. The building and its contents were later buried and replaced with a grain store built directly on top of it.

A Lake Born out of an Earthquake – Earthquakes can fundamentally reshape the landscape, reroute rivers, and even form new lakes. Consider the northwest corner of Tennessee in the early 19th century. Between December 1811 and February 1812, three earthquakes with magnitudes greater than 7 occurred in the New Madrid seismic zone, which encompasses southeastern Missouri, northeastern Arkansas, and neighboring parts of Tennessee and Kentucky. The last of these quakes, on February 7, 1812, centered near New Madrid, Missouri, was especially notable: It temporarily rerouted the Mississippi River, permanently dammed the Reelfoot River, and directed water to fill in a low-lying area to form Reelfoot Lake. More than two centuries later, Reelfoot Lake remains a persistent feature on the Tennessee landscape. An image from Landsat 9 shows the area in late 2023. The area of lake and surrounding wetlands is a state park and national wildlife refuge.

Cats Prey on More Than 2,000 Different Species - Scientists have long known that free-ranging cats—those that spend unsupervised time outdoors—can affect biodiversity by hunting and eating insects, birds, reptiles and mammals. Researchers sifted through hundreds of previous studies, books and reports to put together a database of every animal cats have been recorded eating, as well as the location. In the end, their list featured 2,084 species, which includes 981 birds, 463 reptiles, 431 mammals, 119 insects and 57 amphibians, plus 33 additional species from other groups. Some of the creatures that made the list—including humans—are too large for cats to hunt but reflect their scavenging tendencies. Though the findings are useful, some scientists say they distract from a much larger threat to biodiversity: humans.

Autistic people experience loneliness far more acutely than neurotypical people -Small adjustments to lighting, acoustics, decor and wayfinding, among other sensory factors, can significantly reduce the burden on people with sensory processing differences and open up more social spaces to them.

Inhalable sensors could enable early lung cancer detection - The new diagnostic is based on nanosensors that can be delivered by an inhaler or a nebulizer. If the sensors encounter cancer-linked proteins in the lungs, they produce a signal that accumulates in the urine, where it can be detected with a simple paper test strip. It could replace expensive CT scans for lung cancer (and be more accurate…not as many false-positives).

This Photographer Captured One Image of Cambridge (England) Every Day for 13 Years - After 5,000 photos, Martin Bond has decided to conclude his project, which showcased the city’s mundane and extraordinary moments. “The best thing about street photography ... is that it is possible for the final viewer of a picture to see more than the original photographer—proof, if any were needed, that there is more going on in any moment than a single person can understand.”

Gleanings of the Week Ending January 21, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

How do snowflakes form? Is each snowflake really unique? Why is some snow light and fluffy or heavy? The amazing science of snow – A good topic to explore in the winter! The article includes a video of snow and ice crystal growth.

Falling birth rate in US not due to less desire to have children – People are not having as many children as they say they want, especially at earlier ages. There is some evidence that people reduce the number of children they intend to have as they get older. They may realize how hard it is to have and raise kids in the US…and decide to only have one child rather than two. They may have more challenges conceiving as they get older too. Larger economic and social forces are also impacting birth rates.

Meditation and mindfulness offer an abundance of health benefits and may be as effective as medication for treating certain conditions – An overview of the strengths/weaknesses of studies about mediation/mindfulness…a good introduction.

Drone Photography Celebrates the Beauty of Historic High-Rise Buildings in the U.S. – Wonderful views of the highest parts of tall buildings.

9 in 10 drivers in the US would save money on fuel by going electric – Good! Hopefully the cost of the electric cars will come down a bit…and we’ll have more models to choose from…and the places to charge them during road trips will be convenient.

Why obesity is more dangerous for men – Evidently men have a lot more inflammation associated processes and don’t grow as many new blood vessels in their fatty tissue.

See the Lavish Pompeii Home Owned by Two Men Freed from Slavery – Reopened after 20 years of restoration work. It was originally excavated in 1894-1895.

Broccoli looks more like cauliflower in a warmer world – Looking at the chemistry behind the changed growth of broccoli at higher temperatures…avoiding the change in the lab…but will it enable us to still produce broccoli that looks like broccoli as the planet warms?

Another step toward an insulin tablet - A lot of diabetics would appreciate ‘no more injections’!

Why Electrifying Everything Is a Critical Pathway to Decarbonize The World & Our Lives – I like these articles that get specific about the options that individuals/families can take. It gives me more hope for my future and the future of the planet to take the actions I can to 1) decarbonize the electricity used by my home, 2) move toward an all-electric home and transportation, 3) improve efficiency/reduce waste, and 4) sequester carbon. Focusing on the ‘all electric’ concept this week. I have natural gas powered heating and hot water heater…will probably replace the heating/cooling first. The gas fireplaces are turned off already – removing them is not a high priority.

Last Snow of February 2021

It snowed for a short time on the 22nd – the last snow of the month. I was disappointed with my first foray out to photograph snowflakes.

They looked like pellets although not always sleet spheres like I had photographed earlier in the month. They were very white…and I could see that some were hexagonal even without magnification.

20210222_081814.jpg

When I used my clip-on magnifying lens with my phone – I saw that they were indeed heavily encrusted snowflakes. They were thick enough that the shallow depth of field with the magnification meant that parts were out of focus.

I tried again 30 minutes later and was surprised at how different the flakes looked. They were still encrusted but not as heavily. The temperature was warm enough that there were clumps of icy flakes --- pieces of structure.

My favorite image of the morning was taken during the second session. The lighting caused a little aberration, but I like the glitter of the ice…and the overall shapes.

s 20210222_084318.jpg

At dusk of the same day, the snow was still on the ground as the deer came through; they never stop for very long in our yard. This time they stopped for long enough for portraits. I’m quite sure the animal in the second image saw me in my window!

Overall – it was a winter’s day to enjoy…my routine pursuits with the added spice of snowflake photography and noticing deer staying a few minutes longer than usual in our back yard.

Ten Little Celebrations – February 2021

The biggest celebrations of February 2021 were about my family surviving very cold weather in Missouri and Texas relatively unscathed…..and everyone staying well for another month. Of course – there were a myriad of little celebrations. I easily list one every day – and sometimes choosing what to record is a challenge!

There were more notations than usual about food in February. Some were experiments that were yummy…others were opportunistic:

20210131_160036.jpg

Snow ice cream. We had enough snow this month to make snow ice cream. I always wait for the snow to get at least 3-4 inches deep…then collect the top inch for the snow ice cream. I collect a bowl full then add half and half, chipped peppermint candy/sugar, and vanilla. It’s one of the few times I use my old electric mixer! The challenge is to make only as much as my husband and I can consume right away…we usually each manage a large bowl full. …celebrating a snow day favorite

Broccoli  with orange marmalade glaze. When it’s cold outside, I rarely want salad….this experiment was an easy way to have a ‘hot’ equivalent. I cut up broccoli just as I would for salad, tossed it over a spoonful of orange marmalade in a bowl and microwaved it for a minute or so. A quick stir to coat the broccoli with the melted marmalade, and it was ready to eat! …celebrating ‘hot’ versions of salads

Microwave apple with oatmeal and pecans. I bought a large bag of apples that my husband did not like as well as I thought he would, so I was looking for ways to use them. Breakfast in a bowl seemed to be a good option. I put about ½ cup almond milk in a microwavable bowl then 1/3 cup oatmeal, some brown sugar and cinnamon, a cut up apple, some chopped pecans. Microwave for a minute….stir…microwave for another 30 seconds to a minute…and enjoy. I’ve had it for breakfast several times but realize it would taste good to me any time of day! ….celebrating a new ‘comfort food’

Hot chocolate smoothie. I like smoothies and started experimenting with heating them up. My favorite is made with almond milk, chocolate protein powder, cocoa, banana, and kale. I make it the usual way in the Ninja then put it in a Pyrex measuring cup to heat in the microwave. I stir is several times while I heat…it thickens a bit. ….celebrating a decadent (healthy) treat

There were photography entries on my list too….some attempts that produced images to celebrate.

Snowflakes. There were several snow day during the month so I got several opportunities. I learned to pay attention to the temperature; in general – lower is better! …celebrating the challenge of macro photography outdoors in the snow

High key. This is an example of learning something new….being inspired…and lucky enough to create some interesting images almost immediately! …celebrating learning something new – well enough to be ‘dangerous’

And then there was the variety in the rest of the list:

Multiple virtual birding festivals in one day: Niagara, Laredo, and Bosque del Apache. It was almost overwhelming. We ended up saving some of the webinars until the next day. I was not ‘in the field’ but something that would have been physically impossible: New York/Canada – Texas – New Mexico all in one day! …celebrating the wonders of virtual travel

2021 02 01 IMG_3560 (3).jpg

Quiet snowy Sunday. Sometimes it’s good to have a day to just enjoy the scenery from our windows! …celebrating home

A warmer day in Maryland that Texas or Missouri. Texts were flying across states…the family checking in…worried about water pipes breaking or loosing electricity. My family was lucky enough to come through with relatively few problems! …celebrating family sharing during times of near/potential crisis.

Curbside groceries. I have noticed how different it is from last spring. The shoppers are faster (probably more experienced) and the supply in the store is better. It will be wonderful to shop for my own groceries again but for now I am….celebrating the curbside pickup grocery service.

Sleet and Snowflake Macros

I try to do some photography with my phone and clip-on macro lens with every snow event. On the 13th, the snow event was mostly sleet, but I enjoyed looking at and photographing the tiny spheres of ice. I caught them on a red glass plate...and also scooped a few onto the plate from the surface of the deck. Sleet is more durable to rough treatment that snowflakes! The icy spheres have swirls in them…smaller ones are stuck to larger ones…sometimes there is a visible fracture. My lens is a 65x magnification, so these are very small.

On the 19th, the tail end of our cold weather was snow rather than freezing rain. The temperature was about 30 degrees – a bit colder than my previous snowflake photography forays…and it turned out to be an interesting session. The flakes looked somewhat flattened….not as delicate as they might be if the temperature was lower. But – I didn’t have the challenge of inseparable aggregates that was the norm for my sessions when the temperature was just a few degrees warmer. I used a black acrylic tile to catch the flakes and then to photography them. It sat outside on the covered deck for several hours to cool down. I was pleased with the results…chagrined that I had forgotten to turn on the light associated with the clip-on lens; the pictures would have been even better with the extra light….an improvement I’ll make next time!

Snowflakes (melting)

Trying to photograph snowflakes when the temperatures is in the low 30s is hard. The snowflakes clump as they fall with the temperature that high…and then the melt very easily even if the surfaces and equipment is cooled to ambient temperatures. I’d gathered all my usual equipment: phone (with a clicker to control the shutter on a lanyard) and clip on 65x magnifying lens (with light)…and was quickly frustrated with not very satisfying images toward my goal of photographing individual flakes.

So – I changed the goal and opted to create a series of a clump melting. I did several series and the one below is my favorite. It takes place over only 34 seconds!

Just before I went inside, managed to photograph some spheres on the sleeve if my coat. The magnification shows the black fibers of the coat. I think the spheres were ice (micro hail stones!) and the second one appears to have some crystalline structure inside…maybe a fracture.

Using frustration over a goal that has become impossible to prompt innovation/creativity is probably one of the best resilience strategies of all.

3 Days of Snow

Today our forecast is mostly cloudy…after three days of cloudy skies and snow. The streets are already clear, and the driveway has some clear patches without us ever shoveling. We enjoyed our snow days but are glad to see a bit more sun!

On the first day we had a lot of webinars from the Space Coast Birding and Wildlife which we were watching on the biggest screen in the house (the television) and had a fire going in the fireplace. We had a power failure a little before 8 AM for a few seconds and the cable/internet was out for about an hour afterward. It’s a good thing the first festival session of the day was recorded so we could watch it later!

I tried some snowflake photography twice during the day. I used my phone with a clip-on lens that included a light and a red glass plate to catch the snowflakes. The temperature was about 30 degrees which is on the warm side for good snowflake photography.

The flakes during the first session about 8AM were clumping although there was one that seems to look like a pyramid with a hexagonal base! Even though I had cooled down the plate and lens for over an hour, there was still some melting.

During the second session shortly after noon, it was easier to see individual snowflakes, but they were heavily encrusted with tiny ice spheres.

I tried to capture some scenes from our back and front yard over the course of the day. Our deck and bird feeder still drew the birds even while it was snowing.

I made snow ice cream in the afternoon – after enough snow had accumulated. We ate the whole big bowl!

20210131_160036.jpg

Overnight there was freezing rain so there was an icy crust on everything the second day.

I cracked the ice of the top of the snow on the deck and made snow ice cream again. It was too icy, but we ate most of it anyway.

It snowed more overnight than we though it would so the third day had snow on top of ice. I worried that it might be too heavy for some of the trees because there was some wind as well….but we didn’t hear or see any breakage.  I took pictures of scenes through several windows.

Two of my favorite pictures of the day were taken through the windows on the side of the front door. The vertical ice and snow covered thread in the azalea is an old spider web that’s been there since last fall! The seed pod with a hat of ice and snow is a black-eyed Susan from last summer.

Our plum tree was so full of snow that it obscured the evergreens across the street. The view through the skylights was different too; one had patches of ice partially obscuring the branches of the sycamore in the background.

As always – the view from my office window was the best in the house.

Gleanings of the Week Ending January 16, 2021

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Wingspan and Other Tabletop Games for Naturalists – A new indoor activity for during the winter?

Square Structure Detected Under Monte Albán’s Main Plaza - Archaeology Magazine – The plaza was in use for 1,000 years….and evidently the structure detected with ground penetrating radar, electrical resistance and gradiometery is 60x60 feet…and about 3 feet thick. More study of the data might reveal if the building had stairs, tunnels, and columns.

Leaf microbiomes are a neighborhood affair in northern forests -- ScienceDaily – The microbes associated with trees have been an active research area in recent years. This study looked at Sugar Maples and discovered that their microbiome was similar to the trees around them…whether it was other sugar maples or conifers….other species entirely.

A warm pool in the Indo-Pacific Ocean has almost doubled in size, changing global rainfall patterns | NOAA Climate.gov – The impacts on large-scale atmospheric circulation and rainfall are expected to intensify in the future.

Top 25 birds of the week: January 2021 – This collection includes a photo of a red-breasted nuthatch…a bird we’ve seen at our feeder this year!

Photographer Nathan Myhrvold Captures Snowflakes in High Resolution – I enjoy trying to photograph snowflakes…but I do it close to home where the challenge is higher temperatures. That tends to cause them to clump rather than be easily separated into single flakes. It’s still a fun activity for snow days.

New mammogram measures of breast cancer risk could revolutionize screening -- ScienceDaily – Improving the way mammograms are analyzed…giving results at the time of screening instead of later then moving toward personalized screening thereafter rather than ‘one size fits all.’ I wonder how long it will take for this to trickle through the industry.

Flapper style | Europeana – Our family has a picture of one of my grandmothers in a flapper dress. She probably made it herself – as the article indicated…they were easy to make and patterns were available. The dresses have a timelessness to them even though they are associated with the 1920s. They look great as party dresses even 100 years later!

'Sparkling' clean water from nanodiamond-embedded membrane filters -- ScienceDaily – The problem the researchers are addressing is filtering of the hot water from oil recovery and other industrial processes. We’ll need more technologies like this to clean up water we can’t afford to leave polluted forever….but we should concurrently move toward technologies that don’t leave toxins in water. Technologies should be designed with the goal in mind of 0 waste.

Researchers Catch Oldest Tropical Reef Fish Known to Science | Smart News | Smithsonian Magazine – An 81-year-old midnight snapper! They also caught a 79-year-old red snapper in the same area. Climate change is already warmed the reef enough that the life-span of the fishes there is expected to be shorter in the future. The record for oldest known vertebrate in the world is also a sea creature – a 400 year old Greenland shark.

Snow Day

Sunrise

I kept checking to see if had started snowing even before it was daylight….and noticed the sunrise. It was a good way to start the day even without snow falling.

20201216_090922.jpg

I enjoyed the pumpkin roll I had gotten at the grocery store when I went to buy half and half for the (potential) snow ice cream for my breakfast. It still wasn’t snowing.

Snowing

And then it started. The temperature was 30 or 31….so it didn’t stick immediately to the street and sidewalk, but our deck is raised….and started accumulating snow. Soon there was a dusting. The juncos still found the seeds I’d spilled on the deck…scratching the snow away. The small openings in the mat on the front porch started to fill. Even leave litter turns beautiful with a dusting of snow.

The leaves on the azalea by the front porch caught snow…the occasional red leaf stands out. I went out on the deck to photograph the stairs down to the yard; the dark mound on the landing mid-way down must be racoon poop after one of their visits to our bird feeder.

Snowflakes

All the equipment to try snowflake photography was outside to get cold: the glass plate in a bowl, the magnifiers, the wireless clicker to cause my phone to take the picture. The snow was coming down fast enough that it was a challenge to not get too much on the plate. The snowflakes were often already clumped into larger structures on the way down (there were ‘flakes’ falling that were quite large…gauzy looking). So – not a great day for photographing snowflakes. I did get to experiment with the clip on 65x magnifier with its own light and the 25x jeweler’s loupe. Both are used resting on the plate with the phone positioned above them; it makes it easier to hold everything steady for the photos. Hopefully, we’ll have another snow – an opportunity to try again.

Snow Ice Cream

We got enough snow to make snow ice cream (a little over 3 inches)! I skimmed off the top inch just as the sleet started (later it rained), filling a large bowl. I had already measured out a cup of half-and-half, ½ teaspoon of vanilla, and a cup of pepper candy chips. The snow was still so icy after I used the mixer to blend everything that I added another cup of half and half and even then it didn’t taste as creamy as I thought it would….but it looked pretty with the bit of color from the candy and we ate it anyway.

After 2 bowls of snow ice cream, I was so cold I sat in front of the fire in the fireplace – getting warm on one side at least. It was a good end to our snow day.

Anticipating Snow

We are excited to have snow in the forecast for Wednesday.

Visions of snow ice cream!

20201213_082445.jpg

I previously bought peppermint candy chips to be ready for the winter…sugar and vanilla we always have on hand. So – the ingredient we are missing is half-and-half.

Since last winter we didn’t ever have enough snow to make snow ice cream, my husband and I have decided that I should do a grocery shopping at 1.5 weeks rather than 3 weeks since the last time….for the half and half and other things we’ll need to see us through the holidays (in our case it’s not just Christmas…there is an anniversary and birthday too…all from home this year, connections via Zoom).

Here’s the strategy for making snow ice cream:

Wait until enough snow falls that most of the pollution is out of the air (i.e. 1-2 inches have fallen).

Once there is enough snow – set out all the ingredients (peppermint candy chips, vanilla, half and half, sugar is optional since usually the chips provide enough sweetness, food coloring is optional but helps to know when everything is thoroughly mixed) and the big bowl + electric hand mixer + spatula + serving bowls.

Collect snow with a egg turner or anything with a large flat are to skim the top snow layers and transfer the snow into a large pan. Remember the snow compacts as it makes the snow ice cream. The fluffier the snow is – the more snow the ice cream will require.

Inside quickly put the snow into the big bowl…almost filling it. Add the other ingredients on top. The amounts are somewhat variable since snow has a range of consistencies – I usually start with 0.5 – 1 teaspoon vanilla, 1 cup half and half, and .75 cup of peppermint candy chips. Then mix. Add more half and half if the consistency is crumbly rather than creamy.

Serve and enjoy.

Snowflake Photography!

Another activity to prepare for…probably something to do before enough snow has accumulated to make snow ice cream…photograph snowflakes. I’ve tried it several times in the past. March 2014 was a big year.

2014 03 snowflake3.jpg

I still have glass plates that will work well to catch the snowflakes…provide good background color. They’ll be out on the deck the night before the snow starts to be cold and ready for collection.

I’m going to try my phone with the lighted magnifier first. It’s only 5x so might not be quite enough for snowflake pictures.

I have loupe with a light somewhere that I need to locate. For both I will attach the magnification to the phone with a rubber band.

I’m still thinking about how to get the plate and phone into focusing range (i.e. close) without being handheld (too much heat generated with my hands). I’ll use voice or an external clicker to signal the phone to take the picture. So – I have a deadline of Wednesday to jerry-rig a set up.

Or - I might end up reverting to the loupes that sit on top of the plate and laying the phone on the loupe – the other end on a box to make it horizontal. The trick it to not add too much heat that will cause the snowflakes to melt too quickly!

I am soooo looking forward to a snow day!
