During sunset, a cloud flew in in an amazing shape (a bird, a dragon, and maybe an angel ...)
A little understanding of the physics of cloud formation underscores the complexity of the atmosphere and sheds light on why predicting weather for more than a few days is such a challenge.
Six types of clouds you can see and how they can help you understand the weather.
1) Cumulus clouds - On a sunny day, rays warm the earth, which heats the air located directly above it. The heated air rises upward due to convection and forms cumulus clouds. These “good weather” clouds are like cotton wool. If you look at the sky filled with cumulus clouds, you can see that they have a flat bottom, located at the same level for all clouds. At this altitude, air rising from ground level cools down to the dew point. It usually doesn't rain from cumulus clouds, which means the weather will be good.
2) Cumulonimbus clouds.
Small cumulus clouds do not rain, but if they grow and grow in height, it is a sign that heavy rain is coming soon. This often happens in summer when morning cumulus clouds turn into cumulonimbus during the day. Cumulonimbus clouds often have a flat top. Air convection occurs inside such a cloud, and it gradually cools until it reaches the temperature of the surrounding atmosphere. At this moment, it loses its buoyancy and can no longer rise higher. Instead, it spreads out to the sides, forming the characteristic anvil shape.
3) Cirrus clouds form in very high layers of the atmosphere. They are smoky because they are composed entirely of ice crystals falling in the atmosphere. When cirrus clouds are carried by winds moving at different speeds, they take on a characteristic curved shape. And only at very high altitudes or at high latitudes, cirrus clouds give out rain that reaches the ground.
4) Stratus Clouds - A low-lying, continuous cloud sheet that covers the sky. Stratus clouds are formed by slowly rising air or gentle winds that cover the cold land or sea surface with moist air. Stratus clouds are thin, therefore, despite the gloomy picture, it is unlikely to rain from them, a little drizzle at most. Stratus clouds are identical to fog, so if you've ever walked in a mountainous area on a foggy day, you've been inside a cloud.
5) Lenticular clouds. Smooth and lenticular lenticular clouds form when air is blown up and over a mountain range, and as it travels over a mountain, the air descends to its previous level. At this time, it heats up and the cloud evaporates. But it can slip further, as a result of which the air rises again and forms another lenticular cloud. This can result in a chain of clouds extending far beyond the mountain range. The interaction of wind with mountains and other surface features is one of the many details that must be taken into account in computer simulations to obtain accurate weather predictions.
6) Kelvin - Helmholtz like a breaking ocean wave. When air masses at different heights move horizontally at different speeds, their state becomes unstable. The boundary between the air masses begins to ripple and form large waves, such clouds are quite rare.

Trying my hand at some landscape shots! 😊
You know I scream in my dreams like an animal
I know it feels like it's wrong to be something else
We know those thoughts live with us
sunk down, them nerves much thinner
I crawl, you sob
No sanctuary found
When daylight finally falls
Until the morning comes
My eyes can't see
But I can feel
What is it?
Schrodinger's cat is a famous theoretical thought experiment in quantum physics
If even remotely interested......
There's something called The Copenhagen Interpretation that posits that "things" at the subatomic level don't have any determined properties, only possibilities. A particle can be in two places at the same time, the atom can be in both an excited and unexcited state at the same time, and a photon can be both a particle and a wave.
What determines what we see is our measurement and observation,
Then all the probabilities collapse into one, the one being observed.
Schrodinger wasn't a fan of that theory, so he devised a thought experiment to show how absurd it would be to apply to the gross world of stuff.
He said imagine we put a cat in a box. Also in the box is a radioactive particle which might, or might not begin to decay and emit radiation. If it does, there's a gieger counter which will trigger the release of a noxious gas that will kill the cat.
Then we put a lid on the box.
But until someone opens the box, the cat is both alive and dead.
That's hugely oversimplified, but it's the layman's gist.
This little cat was sitting under a curb on a recessed sewer grate.
So,, is it coming or going or both?
I'm happy to say it was alive. ;-))
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.
-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-
(*) 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.

All that Jazz (Chicago)
Come on babe, why don’t we paint the town?
And all that jazz
I’m gonna rouge my knees and roll my stockings down
And all that jazz
Start the car, I know a whoopee spot
Where the gin is cold, but the piano’s hot
It’s just a noisy hall where there’s a nightly brawl
And all... that... jazz
Skidoo
And all that jazz
Hotcha...Whoopee
And all that jazz
Slick your hair, and wear your buckle shoes
And all that jazz
I hear that Father Dipp is gonna blow the blues
And all that jazz
Hold on hun, we’re gonna bunny hug
I bought some aspirin, down at United Drug
In case you shake apart, and want a brand new start
To do... that... jazz
Find a flask, we’re playing fast and loose
And all that jazz
Right up here is where I store the juice
And all that jazz
Come on babe, we’re gonna brush the sky
I betcha lucky Lindy
Never flew so high
Cause in the stratosphere
How could he lend an ear
To all... that... jazz?
Oh, you’re gonna see your sheba shimmy shake
And all that jazz
Oh, she’s gonna shimmy till her garters break
And all that jazz
Show her where to park her girdle
Oh, her mother’s blood’ll curdle *
Did she hear, her baby's queer*
For all... that... jazz!
No, I’m no one’s wife
But, oh I love my life
And all... that... jazz!!
That jazz!

Close-up of the Orion nebula over dunes at White Sands National Park.
For this shot, due to the park closing not that long after it got dark, I had to set up a tracker, simulate the position of Orion, and then go just outside the park and set it up again and continue stacking data from the sky. Hopefully one day when the park opens up again for backcountry camping, I can re-do this image all from one tripod location. However, the perspective is in fact scientifically accurate, with everything taken at a focal length of 300mm — see 3rd image — so this is in fact an accurate representation of what it would look like at that focal length if our eyes were more sensitive!
This nebula is one of the brightest in the sky, and the brightest parts of it are actually visible to the naked eye, even in a suburban area. It’s up in the skies right now! Go out tonight after it gets dark, and you’ll see a faint blur just below the belt of Orion between the “legs”. Though you’ll only be seeing the very brightest part of the nebula, if you take your camera and star tracker to it you will reveal the rest of these details which are larger than a full moon in the sky.
Fun fact: The white “sand” at White Sands isn’t actually sand. It’s a huge pile of naturally-occurring gypsum, the same stuff that is in drywall :)

Vintage Nikon Digital (CCD Sensor) - 3 (of 15) - Nikon D50 (2005) with AF-S Nikkor 18-55mm 1:3.5-5.6G VR Zoom (F mount) - Photographer Russell McNeil PhD (Physics) lives on Vancouver Island, where he works as a writer.
I think I can place this image in the “never before seen” category. The main subject here is a micrometeorite smaller than a grain of sand. On the sides, we see rough natural diamonds with impurities that cause them to fluoresce. The diamonds are bathed in ultraviolet light, causing them to emit visible light – the diamonds are the source of light for this photo. Light within diamonds illuminating stardust.
Taken with a Mitutoyo Plan APO 20x microscope objective, the full image required 575 frames to focus stack. The stacking was done with a continuous light source, so the best option here is to switch your camera to an electronic shutter. At these magnifications, the mechanical shutter shakes the camera enough to create blurry images when not using flash. The software used here is important: Helicon Focus. It’s by far the most efficient and powerful tool for extensive focus stacking, but more importantly: The company is based in Kharkiv, Ukraine. If you’re into macro photography and microscopy, check them out: www.heliconsoft.com/ - they have a 20% off sale right now.
The situation in Ukraine is optimistic and dire simultaneously, with constant bombardment from Russian missiles aimed at civilian infrastructure. Putin’s Russia is attempting to destroy the electricity grid which would keep Ukrainians in the dark, and without heat. Such an act on its own could be considered a genocide by the Geneva Conventions, on top of the other genocidal war crimes already committed in 2022… and earlier. The true spirit of Ukraine was seen over the holidays, when those without power helped others in their community, uniting strangers for essential aid but also festive cheer.
The world continues to send aid to Ukraine. The first US “Patriot” missile defense system is reported to be en route to Ukraine. A month ago, the Bulgarian government formally announced that they are sending military equipment and weapons to support Ukraine. Weapons manufacturers around the world are making ammunition as quickly as possible to replenish stockpiles from those that have given the Ukrainian military everything they could. The “war machine” around the planet is in motion.
It feels like the world is watching from the sidelines, with the goal of destroying Russia while simultaneously being weary of China. The goal should be for Ukraine to win, but to offer too much support too quickly would possibly cause Russia to back away with a massive military still intact… or use the unthinkably devastating weapons. The goal seems to be wearing down the Russian forces until there is nothing left, while cruise missiles impact on homes and hotels. Innocent lives are lost in the process.
Sanctions appear to be working, but Russian weapons are still being built. Cruise missiles recently launched at Ukrainian civilian targets can be traced to manufacturing dates in September 2022. Drones continue to arrive from Iran, though thankfully they have been largely ineffective on the battlefield and are shot out of the sky. Rumours of weapons shipments from North Korea are gaining credibility. Weapons alone cannot win a war, and Russia is running very low on its most important asset: trained soldiers.
The losses continue in huge numbers, with over 700 Russian soldiers killed in action every day. Many of these men have almost no training, and are being sent to areas such as Bakhmut where the Ukrainian forces decimate wave after wave of frontal attacks, losing no ground in the process.
Soon, the fields will be frozen. New territory will be liberated by the Ukrainian people. I sincerely hope that when the front line is broken once again, the Russian efforts will dissolve along with their current government. Some sources suggest that Putin has a plan to escape to Venezuela if his government collapses, although such things are impossible to verify. This winter will be the most important phase of this global conflict.
Do you sit back and watch? Most of us do. This is a reminder that you can do something to help. Write to your politicians and say that you’d rather Ukraine win swiftly at this point, since Russia is no longer a threat to the West. You can create artwork, you can donate money, and you can vote with your wallet. Personally, I now avoid buying anything from a company that still operates in Russia. You can find that list here: www.dontfundwar.com/directory . There are companies in Ukraine you can support as well – I previously mentioned HeliconSoft, but I’ve purchased some delicious spices from this store: www.ebay.com/str/ethnofoods . I’m certain there are countless other things that can be sourced from Ukraine (I’m a big fan of cast iron cookware made in Ukraine from BIOL and Maysternya).
Stay safe out there, folks. To my friends and family in Ukraine, I think about you every day. Слава Україні!
