Whenever the sun gets obscured by the clouds, the humans step back.
But there are people who are curious and stubborn, and want to figure out how things work, even risking their life in the past.
Meanwhile the Galileo’s Middle Finger is exhibited in the science museum of Florence... Clouds will never win over the light ;p

Uhmm, ouch, Mistress?
What's up? Are you still complaining?
This new toy - it's got twice as much spikes as the old.
Isn't that nice of me? That's only half of the pain for you.
How's that?
Didn't pay attention in physics? p=F/A (*), so if we double the area, the number of spikes that is, we halve the pressure.
But these spikes are sharper than the others!
Hmm, you've got a point there.
One-hundred and fifty, Mistress. In my back.

(*) pressure is force per area. And funnily enough, the abbreviations that were so difficult to learn in german, just seem logical when you're writing in english.

Aurora borealis early May 11 from Deception Pass State Park, Washington. The Adobe Lightroom Denoise AI feature was used to reduce noise, particularly in the reflection.
NGC 6910 is an open star cluster set amidst clouds of gas and dust near the bright star Sadr in the constellation Cygnus.
Subframes for this image were accumulated over 4 different nights, some under dark skies near Goldendale, WA and others from within Seattle city limits. RGB data for the stars was combined with narrowband data for the gas and dust, with Ha assigned to R. In an effort to maintain a "natural" appearance, only modest amounts of SII and OIII data were added to the G and B channels, respectively.

Reflections of some of the buildings of the Institut für Physik (institute for physics) at the technical university in Darmstadt, Germany. This shot was too good to pass by. It may look like there a lot of notes here, but they are in fact the windows frames (danke Sabine für den Wink).

A 4:30am alarm with a quick stop at the Dunkin drive-thru got me to the New Jersey Festival of Ballooning in time to experience what it takes to unfurl, inflate and fly a hot air balloon. It's been years since I've done this and it was a beautiful morning to be amongst all the dedication and skill these crews have.
On another note, felt like it was time to update my profile pic. As much as I liked the old one, it looked more like a high school yearbook pic at this point. Lol!
John Bolin donated some beautiful images....thank you!!! :

I also was lucky enough to obtain permission to use these physics images from a professor of physics who created the diagrams.
Another try of a kind of splash...hmm...I don't know, how to call it. No matter! My first try with "Ink and water". I hope you like it.
And I go on saturday in the holidays for 3 weeks. But I hope to take some nice photos in Saint Petersburg/Russia. Should be a nice city. =)

Just my luck! Not many snowstorms create colourful snowflakes, and when they do they are usually smaller hexagonal gems. I was thrilled to encounter this vibrant flower in a slightly large crystal!
The colour here is well understood, but still magical. It’s not colour in the same sense as you would paint with (the paint would absorb certain wavelengths of light and reflect others, you see the reflected light), but rather generated through optical interference. This is the same physics that generates colours in soap bubbles, but in a snowflake is often much more structured.
One way or another, a bubble forms in the ice. The thickness of this bubble dictates the thickness of the ice on either side of it, and shifts in this thickness will change the resulting colours. Light bounces off of reflective surfaces, but a snowflake is ice, not a mirror; some light still enters the snowflake and reflects back off of the additional boundaries between ice and air. When light passes through a denser material (ice), it slows down, and when it reflects back out, it speeds up again. This is critical. If the distance traveled through the ice is small enough, the two rays of light will rejoin, but half of it will be “out of sync”. This causes some wavelengths to cancel out while others are added together, generating specific colours from otherwise white light. Very similar principals apply to sound waves and interference.
Once the bubble is completely enclosed, things can still change. Water molecules can break away from their crystal structure (sublimation) and re-attach elsewhere. This might slightly change the thickness of the ice in certain areas but in a gradual fashion. I suspect this is the reason for the gradient from yellow to magenta at the tips of the internal “petals”.
The central bubble here is fascinating for other reasons as well – just look at the outer edge of it. Notice these little “nubs” in each corner? Imagine the snowflake being just that big. Those little nibs would be the last elements to stay open to the outside air before shifts in temperature and humidity allow the outer edge of the snowflake to become whole again. What’s interesting here is that a snowflake typically grows fastest where it has the greatest access to water vapour – the corners. Why then did the corners take the longest to close up? Moreover, why did the middle of each prism facet also have a nub, which continued to progress a line-like bubble that eventually evolved into a sectored-plate design?
It’s a beautiful physics puzzle and fun to spend some time imagining how and why it came to be.
Shot on a Lumix S1R with a Canon MP-E 65mm macro lens. I’ve used a lot of ring flashes over the years, but my favourite is also one of the most affordable – the Yongnuo YN-14EX II: www.bhphotovideo.com/c/product/1462725-REG/yongnuo_yn_14e... . It’s better in many ways than Canon’s own MR-14EX II, and it’s what I’ve been using to shoot the snowflakes in this year’s series. For more tips on snowflake and general macro photography, you can also check out my upcoming instructional book, Macro Photography: The Universe at Our Feet - skycrystals.ca/product/pre-order-macro-photography-the-un...
For those curious about how the book is progressing? Coming along nicely! Most of the book is just undergoing revisions and grammar checks but there is still more work to be done. I appreciate your patience. :)
Sixty Degrees. That’s the angle for all of these edges, give or take based on the fact that the snowflake is photographed at an angle. Physics at work, yet many people consider snowflakes as a creation of God. It’s amazing really, that the same object can be described by some as evidence of a Creator, while others use the exact same object to prove that the natural laws of physics make our world what it is.
Very few things can take equal sides like a snowflake. I have a side, but I don’t need to express it to express my fascination with our interpretation of the world around us. The real magic here is that we, as human beings, see this snowflake as beautiful. I don’t think many people would argue against that. That begs the question however: what is beauty?
Beauty doesn’t exist on its own. A massive organized collection of water molecules? It is just a thing, a (mostly) inanimate object when we see it. How do we perceive this as beautiful? It’s not the object that contains this value, it’s our perception of it. One could say it’s all in our heads, and I think they’d be right. Something is only beautiful because we say so, collectively or individually it doesn’t matter. So then, what is beauty?
It’s a deep question, and one that every person might have a different answer to. My answer reflects on the larger world around us. We see geometry as standing out from chaotic nature. We admire patterns. We adore symmetry. The most symmetrical face with chiseled lines might be perceives by many as being beautiful, but so too will a wrinkled old smile with the history of the world written on it. Beauty comes in many forms, based on how deep we look.
When I dive into the details of a snowflake, describing all of its features and how they came to be, I hope I add to the beauty. In the opening words of the documentary series Forces of Nature, narrated by Dr. Brian Cox, he says “the world is beautiful to look at, but it’s even more beautiful to understand”. Understanding the depth of beauty only makes these tiny sky crystals even more beautiful, and these posts are often aimed solely at this.
See the slightly brighter center? There is a hexagonal twin plate on the reverse side of the snowflake. The central “dot” shows that this was from a column that transitioned to plate-type growth, and the forward-facing plate gained dominance to grow branches. It was slow-growing which provides a more geometric profile, with extra complexities in the lower left – look closely and you’ll see signs of another plate running in parallel in certain areas.
But all of the science, all of the logic, have a hard time explaining beauty. Whether or not there was a master plan from God to put this snowflake in front of me or if it was just the natural chaotic physics of the universe, doesn’t really matter when we internalize our appreciation of the results. No matter what you think, this snowflake is beautiful.
That is the beauty of humanity.
P.S. if you want to comment on this image, please do so in a way that does not take sides on religion or science. We ALL have our opinions, let’s just keep this one human, okay?
I was one of those kids who actually liked going back to school. It was a place for hands-on discovery. For Macro Monday's theme: back to school
I am studying it at school, and went to the Great Lake Science Center and saw this experiment about the vibration of the strings. Cool stuff!

For every action there is an equal or opposite reaction. But does that apply to gods, super humans, and aliens? I've seen things that would change the very way people live. I changed my past, and then had to deal with the consequences of my action. I have stood before the most powerful and evil person in my universe, and refused to bow. Yet in my lifetime nothing like this has happened before. Over night new continents just appeared, cities were destroyed because two things can not exist in the same place, new types of people exist now--some can change there entire physiological without even blinking. We still don't know what the consequences of this will be, but I fear grand ones are in store. Some of these could come by our own hand--people have always protected there homes, there always will be, and ever since this "collision with another reality" it has caused allot of chaos. Some people call us terrorist and they demand our lives. Of course like us there are ones that take the law into there own hands; I've called for a conference and they have agreed to talk.
"Hello. The names Tony Stark, first time I've had to introduce myself. I'm here, to discuss under what circumstances your going to turn yourself over."
"We're not going to, in our world we are American citizens too." says Superman.
"And in your 'world' do you level entire cities?" Tony retorted.
Wonder Woman then said, "We would never do such a thing--we fight against those type of people."
"Well, so do we sister. We call ourselves the Avengers...well to make a long story short, we have a team of supermen and there's four of you. Come quietly please..."
Batman very calmly steps forward and looks Tony in the eyes and says, "What makes you think that there's only four of us?"
