Someone told me once that regardless of degree completed, a "Physicist" is just one who studies physics. In that context, I like to think of myself a physicist moreso than any of my other professions or skills. Which are humorous in number at this point.

Took another sunrise trip to Point Judith this morning, to put the M11-P to use with the Thambar. A bit cloudier than I’d hoped for, but a beautiful scene nonetheless the less.

A lighthouse stands off in the distance in the center of the frame on an early fall morning. The clouds are thick, but sunshine is visible peaking out of the upper left. The shoreline stretches from the middle left of the frame across to the lower right, there’s just enough light to make out the dark green of the grass. The sea, while not calm, is not overly rough. A soft glow permeates the frame, emphasized heavily by a halo surrounding the lighthouse light.

SEALS!

#photography #wildlife #getoutside
In the distance, some harbor seals can be made out resting on top of a rock in the bay. The rock is visible because the tide is low. The camera used to photograph the seals. It sits atop a tripod with a long 600mm telephoto lens mounted. The seals are not very close.

My attempts to photograph harbor seals yesterday afternoon and c/2025 a6 Lemmon last night were a bust, but in the process I did get to photograph this phenomenon of a rainbow occurring inside a cloud. So the day wasn't a total loss.

#photography #rainbow #nikon
A thin whispy cloud is partially colorized internally by a "rainbow" showing hues of yellow, orange, and red on it's westernmost end (towards the right of the frame). The cloud itself is on the lower left, and the rainbow effect is near the center of the frame. A contrail from a commercial aircraft can be seen stretching from the lower right to the upper left of the frame.

Comet c/2025 a6 Lemmon!

Shot with Nikon Zf + 600mm PF f6.3

A photograph of comet c/2025 a6 Lemmon. The head of the comet is centered in the frame and the tail stretches towards the upper right corner of the frame. The area around the comet is slightly hazy and stars dot the background.

Another shot of the Point Judith lighthouse during sunrise on October 25th.

#sunrise #photography #leica
Sunrise behind the Point Judith Lighthouse. The lighthouse is in the lefthand side of the frame and the sun pokes out just barely to its left, enough to make a vertical lens flare. The coastline curves up down the middle from top to bottom and the Atlantic Ocean is to the right. Some offshore windmills can be seen in the far background and the sky blends from orange and red low on the horizon to light shades of blue towards the top of the image.

Since I'm currently in R.I. and also watch @khill.bsky.social I figured I'd take a trip over to the Carter Preserve to see the former site of United Nuclear's reclamation facility. Here's the panoramic. Might be cool to return with a metal detector and radiometer if that's legal here.

Izzy dog.
A black and white photo of a pibble mix dog named Izzy has tucked herself cozily in the corner of a couch, the greying of her black fur visible around her eyebrows, muzzle, and paws. Her left paw rests on a pillow towards the camera, just out of focus.

Got to go on a trip to Jim Thorpe, PA with my wife over Labor Day weekend. It's a very nice small town, maybe next time we'll be able to ride in the observation car.

Shot with a Nikon Zf and 135mm Plena.

#trains #scenicrailroad #scenic #scenictrain #nikon
A photograph taken out the window of a scenic train ride near Jim Thorpe, PA. The left hand side of the frame is fuzzily obscured by the edge of the windowframe itself, the train curves to the right ahead of the window on tracks lined along the edges with large gravel. The train is a vibrant red with a silver roof. To the right of the tracks lies a pedestrian pathway heavily shaded with patches of light poking through the trees and the route is lined by dense and vibrant green trees.

30 mile ride on the Washington Secondary Trail in Rhode Island today.

Wish I had my Capra with me, but it is wayyy easier to travel with the @bromptonbicycle.bsky.social

I do a lot of photography, and like to take advantage of the rendering of vintage lens designs, and also lenses with extreme optical properties, both examples below were vintage optical designs (50s and 60s)
A black and white portrait of a fluffy husky lying on a cushion, head perked up facing the camera. She makes eye contact with the camera, the back-ground is off-white grey and her hindquarters are out of frame. In the distance a silhouetted lone individual walks across a landscape towards civil war era artillery cannons in Manassas National Battlefield park.

A husky looks into the camera, mouth open tongue poking slightly out. The background is blurry but hardwood floors and a table can be made out.

Learning how to use a flash again since I’m shooting a wedding next weekend.
Izzie dog lounging on the back of a couch staring out a window. Her fur is mostly black but greying around the muzzle.

Nyx the husky chillin' on the couch. I really do love me some vintage lens designs (this isn't an original Noctilux f1.2, it's the remake, still an outstanding lens)

#dogsky #photography #monochrome #leica
A high contrast portrait oriented black and white image of a husky sitting on a cushion against a white background. The upper half is mostly empty grey space while Nyx herself occupies the lower half of the frame. She faces the camera while her paws point towards the left hand side of the frame (Nyx's right). Her head is largely centered. Sharp contrasting lines stand out everywhere a shadow falls making the outline of her fur pattern very distinct.

Radar wondering why I'm waking him up from his snooze by pointing a camera at him instead of giving him snuggles

I'm getting better with the 600mm lens. This was taken over by Bull Run along the Occoquan river.

#blueskyartshow #photography #wildlife #outdoors
In the lower half of the image A bird of prey flaps its wings after an unsuccessful fishing attempt. The disturbance in the water trailing behind it can be seen along the surface, and the bird itself is only inches above the surface, maybe a foot. The upper half of the image is obscured by green foliage, the river water is a murky brown. The alt text author does not know the species of bird.

Good evening Bsky

A freshly fallen white flower sits among leafy detritus on the rain soaked ground. Surface tension holds together dozens of droplets on the surface of its petals and its stamen droop forward from its center. The leafy green of its parent plant visible in the bottom left hand corner.

Have a couple of dog photos to brighten your day.

#photography #dogsky
An American foxhound midstride running almost straight towards the camera among mid height grass and dandelions on the righthand side of the frame, ears flopping as he goes. A husky pants mid stride as she runs across the frame through mid height grass, ferns, and dandelions. Tail and ears both perked up in excitement, both front paws off the ground.

So I decided to play around with the 3n+1 problem, but instead of searching for a value, I decided to generate scatter plots of how many times the algorithm runs before reaching zero.

@standupmaths.bsky.social I'm not entirely certain if there's some kind of patern to the cycle?
The python code reads the following: import numpy as np from matplotlib import pyplot as plt # from numba import jit, cuda, vectorize # @cuda.jit(device=True) def threeNpOne (x): count = 0 n = x while(n != 1): if n % 2 != 0: n = (3*n)+1 elif n == 0: n = 1 elif n % 2 == 0: n = n/2 count += 1 return(count) # for i in range(1,100000001): # print(threeNpOne(i)) x = np.arange(1, 100000, 1) y = np.array([threeNpOne(i) for i in x]) plt.figure(1) plt.scatter(x, y) plt.show(1) x2 = y.copy() y2 = np.array([threeNpOne(i) for i in x2]) plt.figure(2) plt.scatter(x2, y2) plt.show(2) x3 = y2.copy() y3 = np.array([threeNpOne(i) for i in x3]) plt.figure(3) plt.scatter(x3, y3) plt.show(3) And produces a scatter plot with a lot of dots in it. There looks to be some kind of repeating curve pattern, but the author of this alt text has no idea.

A short Sunday adventure on the C&O canal near Harpers Ferry. Ridden on the @bromptonbicycle.bsky.social G-Line and shot on a Nikon Zf. (Wife rode a canondale)
A small turtle sits behind a great big turtle on a sandbar along a river. The greens of an algal bloom coat the surface of the water. A total of six (by the authors count) turtles sit comfortably on some logs that stick out of the water along the C&O Canal. Algae is evident on the surface of the water, and moss creeps up the sides of the logs. A folding bicycle with front and rear bags attached stands upright and unfolded nestled in a bike rack. The entrance to the train thnnel at Harpers Ferry. It he concrete arch stands squared away and set inside the side of a mountain displaying the name of the town and the year 1931. Tracks of wood and steel enter the tunnel beyond line of sight.

Some photos from a few months ago when we had a big snow in Northern VA.

A husky is seen running towards the camera through a hazy flurry of snow kicked up as she runs. Nyx the husky stands majestically in the snow. A wooden fence and yellow wheelbarrow are visible just out of focus behind her.
