We know that all Prime numbers, after 2 and 5, end with either a 1, 3, 7 or 9 as their last digit.
If we look at the frequency of individual last digits we can see that 1, 3, 7, or 9 more or less occur at a similar frequency. However, as soon as we look at the frequency of the same last digit occurring twice in a row, we find that this is far less common and even less common for the same last digit occurring three times in a row.
Kannan Soundararajan and Robert Lemke-Oliver produced a paper in March 2016 on this apparent bias which received considerable attention in mathematical journals www.quantamagazine.org/mathematicians-discover-prime-cons.... If you really want to dive into the maths, the full paper can be found here arxiv.org/pdf/1709.06168.pdf .
I found this old gem in a flea market near Ipoh old town couple of weeks back. Pretty cool retro looking radio though and it's still in pristine condition. Wonder if it's still working as the original box and user manual are still intact.

Oh, how I admire these marvelously engineered, composed and exposed hi-tech Strobist shots, such as of a floating CFL shining brightly without being mated to a socket or any wires visible. For example, this floating CFL, the Strobist explanation and the link to the article by David Hobby were an inspiration to try a lo-tech version.
Strobist Info:
Bulb is a 110V 5W as bought, with a red coating and old-fashioned tungsten filament. Although the thread and contact are dark and hard to see in this shot, no wires are attached to it. No photo editing, simply not needed. This is the image straight out of the camera, just cropped. No fancy floating either, this bulb just rests on the dark backdrop inside my small lightbox that is illuminated by a rainy day cloudy sky through the window shade pulled up about a hand wide. No flash used, no snooting. Why then Strobist? Well, the creative spirit of sharing explanations may have to do with it.
Before I bluntly share, can you guess how I lighted up that bulb? It is without wiring, without building an LED into it, with neither radio frequency transmission nor microwave energy, and not resorting to magic hands energy or wishful positive thinking, either.
Three visual cues:
1. the reflection on the Edison socket,
2. the reflection on the bulb body
3. a bit of light spill to the right side of the bulb. View On Black
Got an idea? The light source is (drum roll) a laser pointer, carefully aimed at the far side of the red globe. See that same little red light bulb when OFF.
36/365: lost frequency
everyone is walking on the edge of life
like a ghost of a shadow, barely alive
even time’s in a rush
but it’s going nowhere
everyone’s connected but no one is connecting
the human element has long been missing
tell me, have you seen it?
have you seen it?

Senior Airman Dustin Harris, left, and 1st Lt. John Day, center, discuss radio frequencies with a Soldier assigned to the 82nd Airborne Division during an exercise in frequency hopping at Fort Bragg, N.C. Frequency hopping is changing regular frequencies during transmission, a radio operation technique that ensures secrecy and protects against communication channel jamming. Day and Harris are tactical air control party members with the 14th Air Support Operations Squadron. (U.S. Air Force photo by Airman 1st Class Alexander W. Riedel)

I love happy accident shots.
Never intended for this shot to look this way.
But it does.
Huzzah, photo miracles. Filling the gap left by lack of talent!
I Am But A Traveler in This Land & Know Little of Its Ways
BY DEAN YOUNG
Is everything a field of energy caused
by human projection? From the crib bars
hang the teething tools. Above the finger-drummed
desk, a bit lip. The cyclone fence of buts
surrounds the soccer field of what if.
Sometimes it seems like a world where no one
knows what he or she is doing, eight lanes
both directions. How about a polymer
that contracts in response to electrical
charge? A swimming pool on the 18th floor?
King Lear done by sock puppets? Anyone
who has traveled here knows the discrepancies
between idea and fact. The idea is the worm
in the tequila and the next day is the fact.
In between may be the sacred—real blood
from the wooden virgin’s eyes, and the hoax—
landing sites in cornfields. Maybe ideas
are best sprung from actions like the children
of Zeus. One gives us elastic and the omelette,
another nightmares and SUVs. There’s considerable
wobble in the system, and the fan belt screams,
waking the baby. Swaying in the darkened
nursery, kissing the baby-smelling head:
good idea! But also sadness looking at the sea.
The stranded whale, guided out of the cove
by tugboats, turns and swims back in.
The violinist will not let go her violin
which is 200 years old and still on the train
thus she is dragged down the track.
By what manner is the soul joined to the body?
Answer: an arm connecting a violin
to a violinist. According to Freud,
there are no accidents. Astrologists
and Presbyterians agree for different reasons.
You fall down the stairs with a birthday cake.
You try to fit a blunderbuss into a laptop.
Human consciousness: is it the projector
or the screen? They come in orange jumpsuits
and spray the grass so everything dies
but the grass. It is too late to ask Kafka
what he thinks. Sometimes they give you
a box of ash, a handshake, and the rest
is your problem. In one version,
the beggar turns out to be a king and grants
the poor couple a castle and a moat and two
silver horses said to be sired by the wind.
That was before dentistry, which might have been
a better gift. You did not want to get sick
in the 14th, 15th, 16th, 17th or 18th centuries.
So too the 19th and 20th were to be avoided
but the doctor coming to bleed you is the master
of the short story. After the kiss from whom
he will never know, the lieutenant, going home,
touches a bush in which birds are singing.

Lockheed Martin’s sixth Advanced Extremely High Frequency (AEHF-6) protected communications satellite is encapsulated in its protective fairings ahead of its expected March 26 launch on a United Launch Alliance Atlas V rocket. AEHF-6 is part of the AEHF system -- a resilient satellite constellation with global coverage and a sophisticated ground control system -- that provides global, survivable, protected communications capabilities for national leaders and tactical warfighters operating across ground, sea and air platforms. The anti-jam system also serves international allies to include Canada, the Netherlands, United Kingdom and Australia.

Back when the East Perth Power Station was built (around 1916) the powers that be asked a renowned electricity expert what frequency the station should generate at. He recommended 50 hertz, so (naturally) they decided to build the station at 40 hertz.
This was fine for a while, but by the 1940s 50 hertz was established as the standard, and East Perth's eccentric 40 hertz was causing big problems on the power grid. The solution was to build a big-ass transformer to kick the frequency up ten hertz and route the entire station's output through it.
Which is what they did - constructing the frequency switcher building to hold it.
Ain't industrial history grand?

CAMP WILLIAMS, Utah, June 25, 2015 - Georgia Army National Guard Spc. John Pettas loads frequencies into a Single Channel Ground to Air Radio System (SINCGARS) in preparation for delivering a situational report (SITREP) during the national "Best Warrior" competition's eight-station warrior tasks event.
This event tests competitors on warrior tasks including land navigation, searching an individual and employing a live 240 claymore mine.
