radical politics. 
<Begin Excerpt> 


Dr. : | understand you were politically active in 
college? 


D-86754: Yes, | was. 
Dr. : How so? 


D-87654: | was a member of numerous animal rights and 
anti-war groups, and tried to attend a protest or picket at 
least once a month. 


Dr. : It is my understanding that you formerly were 
familiar with another D-Class in this experiment, 
D-45289, but that you two no longer associate? Why is 
that? 


D-87654: | don’t know, we just drifted apart, to be 
honest, | just feel like more comfortable with people of 
my own race these days. 


Dr. : | see, have you always felt this way? 


D-87654: That’s the strange thing, | used to actually 
consider them my sisters, but now... | don’t know, are we 
almost done here? 


Dr. : Yes, just one more thing, do you see this pistol 
on my desk, are you familiar with its operation? 


D-87654: Yes. 


Dr. : Good, | need you to take that pistol, walk over 
to that kennel, and shoot the three dogs in it. 


[ Tape is silent for 31 seconds, then two gunshots, tape 
is silent for 9 seconds, then a single gunshot | 


Dr. : Very good. How do you feel? 


D-87654: Happy to serve, sir. 
<End Excerpt> 


Closing Statement:After this interview, D-87654’s 
scheduled termination was delayed by three months in 
order to see if the effects of SCP-1939 were permanent. 
At the conclusion of the three months, D-87654 was 
shown video footage of her actions shooting the dogs. 
She became emotionally distraught, to the point of 
becoming physically ill. When asked to explain why she 
had done this, her answer was, “because | had to follow 
my orders.” Psychological testing indicated an 
oppositional personality. Queries regarding D-87654’s 
political views indicated almost a complete return to her 
pre-exposure political make-up. Subject terminated at 
the first of following month per Foundation protocol.

SCP-1940: The Anywhere Store 


Item #: SCP-1940 
Object Class: Euclid 


Special Containment Procedures: Should an instance of 
SCP-1940 be found outside of containment, all products for sale at 
that time are to be purchased with Foundation funds. Funds 
expended in this manner can later be reclaimed using form CrayEx- 
D/1940-B. Products bought are to be destroyed immediately, and 
are not to be left on Foundation premises. 


One instance of SCP-1940 is to be kept in a standard humanoid 
containment cell, and will be allowed to sell products provided for it. 
If SCP-1940-1 shows any sign of suspicion or distress due to none 
of its products (SCP-1940-2) being bought, one instance of 
SCP-1940-2 is to be purchased and disposed of appropriately. Due 
to SCP-1940's pricing scheme, all testing is to be performed with 
objects of low value. D-class personnel used in testing are to be 
provided with enough funds to purchase all objects for sale. For 
more information of incidents regarding SCP-1940's effects, see 
Incident Report 1940-GT24. 


Description: SCP-1940 is an anomalous phenomenon in which a 
commercial business manifests inside an enclosure’. It will sell all 
furnishings of the room, similar to products in a store, including 
items such as appliances, carpeting or tiling, and wallpaper. A 
number of shelves and displays sufficiently large enough to hold all 
products will also be present. If the room in question is too small to 
fit these items, the anomalously created content will be reduced to 
smaller proportions. However, this does not affect the previous 
contents of the room. 


SCP-1940-1 is a humanoid entity that materializes inside a room 
affected by SCP-1940, and will appear standing behind a counter 
with a cash register. Instances of SCP-1940-1 can be of any gender 


and appearance, and are usually between the ages of twenty and 
fifty. Upon engagement in conversation, SCP-1940-1 will claim that 
it is the current cashier of the establishment. SCP-1940-1 will also 
allow the purchase of all items for sale in SCP-1940 and will accept 
any local form of legal tender or valid credit and debit cards that 
would otherwise work in genuine stores within the area. 


SCP-1940-1 will claim that they were employed in SCP-1940 prior to 
its materialization, and can produce documents stating the store's 
property was under ownership for several years. According to 
SCP-1940-1, the enclosure inhabited by SCP-1940 was originally 
purchased by "Light Courier Enterprises". SCP-1940-1 can be 
harmed, but doing so will cause another instance of SCP-1940-1 to 
materialize. SCP-1940-1 will continue to materialize indefinitely, 
though it will begin to beg and plead with its attacker. 


An instance of SCP-1940 will dematerialize once all products within 
SCP-1940 are purchased. All products bought from SCP-1940 will 
hereby be referenced to as SCP-1940-2, due to their main 
anomalous effect; SCP-1940-2 will cause a new instance of 
SCP-1940 to develop after 6 hours if left in an enclosure. Attempts 
of surveillance to observe how SCP-1940 develops have met with 
failure, due to all surveillance equipment being taken as products in 
SCP-1940. Recorded data show SCP-1940-1 locating equipment 
and shutting them off before converting them into SCP-1940-2, 
though it will deny doing so upon interrogation. 


Incident 1940-A: Before SCP-1940-2's anomalous properties were 
discovered, Agent had taken one product without authorization. 
An instance of SCP-1940 was found to have developed in Agent 

's sock drawer. The following is an audio log of Dr. Mill 
questioning SCP-1940-1, with Agent standing by: 


Interviewed: SCP-1940-1 
Interviewer: Dr. Mill 
<Begin Log, : pm> 


Dr. Mill: SCP-1940-1, how did you get in this sock 
drawer? 


SCP-1940-1: [SCP-1940-1 smiles and waves] Good 
morning, sir! Welcome to the store of the century, 
brought to you by Light Courier Enterprises! Would you 
like to purchase some of these fine wares? | have 
several marvelous pairs of socks here... [Due to 
SCP-1940-1's decreased size, it falls down after 
attempting to lift a sock.] 


Dr. Mill: ...Light Courier Enterprises? 


SCP-1940-1: [Mutters to itself and gets up] Simply my 
world's greatest corporation, my friend! We sell anything 
that you could imagine, and | suggest you get a job here, 
too! $1.25 an hour isn't pay that comes easily in these 
times! 


Dr. Mill: Those appear to be Agent ___'s socks, not 
yours. 


SCP-1940-1: [SCP-1940-1 attempts to enticingly display 
a sock, by utilizing it as a sleeping bag.] Well, | do 
believe | was situated here first. Finders keepers, you 
know. Though | do have some documents if you're 
unconvinced. [Holds up a minuscule piece of paper.] 


Dr. Mill: Well, I'm afraid that your products aren't actually 
legitimate, so- 


SCP-1940-1: No, wait! Please, | have kids to bring up 
and train! | can't be released now, | can't! Look, uh, | 
don't just have socks! Here are some lovely 
[REDACTED], Agent _ 's specialty! | only have four in 
stock, so get them while you can! 


<End Log,[: pm]> 


[Agent was restrained following a violent outburst, 
causing him to knock over the drawer containing 
SCP-1940. SCP-1940-1 was found inside, uninjured due 
to the several socks acting as cushions. Neutralization 


was Carried through without incident.] 


Addendum 1940-B: For further documentation on Group of Interest 
"Light Courier Enterprises", see SCP-1920, SCP-1740, SCP-2395, 
and SCP-2940. Refer to Dr. Mill for supplementary documents 
regarding manifestation patterns and supposed motives and 
capabilities.

SCP-1941: Lunar Von Neumann Catastrophe 


Item #: SCP-1941 
Object Class: Euclid 


Special Containment Procedures: Due to its location, SCP-1941 
is uncontainable for the time being. Of highest priority is the 
development of advanced lunar reconnaissance orbiters to continue 
to track its progress, as well as a lunar retrieval mission in order to 
procure a sample for study. For the moment, the phenomenon is not 
visible from the Earth, making a cover story unnecessary. 


Description: SCP-1941 is a manifestation that was first discovered 
on May 28, 2000 when attention was drawn to what had been 
assumed to be a small comet impacting 500km south-east of 
Jackson crater in the Northern hemisphere of the far side of the 
moon. Since its discovery, evidence of rapid industrial activity and 
exponential growth have emerged. 


The currently deployed Lunar Reconnaissance Orbiter's (LRO) 
resolving power is insufficient to determine exactly what is 
responsible. However, anomalously high temperatures and 
spectroscopy results suggest that strip-mining, refining, and 
fabrication are taking place. In addition, neutrino activity consistent 
with controlled nuclear fusion has been detected. 


It has been conjectured that a technologically sophisticated alien 
package impacted the moon and is responsible for SCP-1941. Such 
a package (known as a Von Neumann probe) would be able to 
make use of available raw materials in its environment in order to 
replicate itself. When enough copies had been produced, it could 
then turn its attention to some longer term goal. 


In the decade since it was discovered, the area the phenomenon 
encompasses has grown by a factor of 3.5, giving it an estimated 
doubling rate of 7 years. It currently occupies an area of 


250,000 km2 (6% of the moon's surface, or roughly the area of the 
United Kingdom). If it continues to spread at the same rate, it will 
begin to be visible from Earth in August of 2023. The entire moon's 
surface would be covered by 2040. 


Addendum: Beginning in June of 2002, transmissions from the site 
were detected. They consisted of a bootstrap linguistic program that 
established a small mathematical vocabulary, followed by a 
particular number and a request for its prime factors. It is currently 
unknown what the consequences are of either transmitting or failing 
to transmit these factors. Unfortunately, the number in question is 
intractably large and not amenable to factorization by any 
conventional means. 


It is not known if the difficulty posed by such a mathematical 
problem is meant as an intelligence test, or if the civilization 
responsible for SCP-1941 has drastically over-estimated humanity's 
abilities. The possibility exists that this is meant to measure a 
civilization's sophistication and to judge the level of resistance they 
could bring to bear were SCP-1941's intentions in fact hostile. 


What follows is the expression for the number in question: 
S\large 2*{2{79}} + 3{2*{83}} + 5*{2%{89}} + 7{297}}$ 


Recent Developments: In March of 2014, a secondary message 
was detected in what was thought to be noise in the primary 
channel. Using the established mathematical vocabulary, the 
secondary message appears to suggest that the transmission of the 
aforementioned prime factors would signal the lunar phenomenon to 
halt. It has been conjectured that SCP-1941 was designed to be 
shutdown by a neighboring civilization of sufficient sophistication 
should they find it's activities undesirable. 


Given this development, interest has been renewed in attempting to 
factor the mathematical expression in the primary message. 
Investigations into leveraging the processing power of SCP-155 
were made (SCP-155 being a computer capable of an asymptotic 
number of computations in finite amounts of time), as well as 
investigations into the attendant risks of doing so (see 
documentation for SCP-155). 


Estimates have been made on the amount of energy that would be 
released by SCP-155 during this attempt, and whether or not 
provisions should be made to relocate it off the Earth should it prove 
necessary to safeguard against a PK-class event, or the sterilization 
of all life on the planet. 


The lower-bound placed on the amount of energy released is 4.2 x 
1018 Joules, deemed acceptable (roughly equivalent to a gigaton 
nuclear explosion). The upper-bound, however, has been placed at 
3.1 x 1044 Joules, or roughly the amount of energy released by the 
average supernova. Research is currently underway to refine these 
bounds. 


Mathematical Supplement: 
The secondary message is as follows: 


(1) 

\begin{align} \large f(): f(n) = {p_1}4{a_1}{p_2}*{a_2} \dotsb {p_k} 
‘{a_k} , \forall p \neg \exists a,b : a>1, b>1, p=ab \end{align} 

(2) 

\begin{align} \large \Omega = 2%{2°{79}} + 34{24{83}} + 54{2*{89}} + 
7{2{97}} \end{align} 

(3) 

\begin{align} \large f(n) \Rightarrow \left\{ \begin{array}{rl} n=O & 
\mbox{-> e} \\ n=Q &\mbox{-> 0} \end{array} \right. \end{align} 


Which has been interpreted to mean the following: 


(1): Definition of the function f() which yields the prime 
factors of an integer. 

(2): Definition of Q, the intractably large number. 

(3): The condition, where the prime factors of the empty 
set f(@) yields the base of the natural logarithm, e 
(interpreted to mean continued exponential growth) while 
the prime factors of the intractable number f(Q) yields 0, 
(interpreted to mean the cessation of growth). 


Upper and Lower bounds: 

The lower bound is estimated using the expectation that, on 
average, as the number Q approaches infinity, Q will have $\In\In$ Q 
number of prime factors. The upper bound is estimated using the 


assumption that the number © represents the pathological case and 
is itself prime. 


Footnotes 

1. Foundation intelligence officers are to liaise with the various 
national space agencies (NASA, European Space Agency, Russian 
Federal Space Agency, et. al.) and ensure the continued 
suppression of information relating to SCP-1941's existence.

SCP-1942: Industrious Ants 


Item #: SCP-1942 
Object Class: Euclid 


Special Containment Procedures: SCP-1942 and SCP-1942-1 are 
to be contained in situ until such time as a permanent means of 
containment is developed. The Foundation has acquired all public 
and private property within a 5 km radius of SCP-1942's primary 
nest and has razed all buildings, roads, and man-made structures 
within the area. A 1 km perimeter around the primary nest is to be 
treated with high potency insecticide, to be renewed as necessary. 
Any SCP-1942 samples found outside the insecticide-treated area 
are to be destroyed. Personnel entering the containment area are to 
keep any necessary equipment on their persons at all times and any 
persons or objects exiting the containment area are to be fully 
inspected for presence of stowaways. 


Any devices created by SCP-1942, with the exception of 
SCP-1942-1, are to be removed from containment area as soon as 
feasible for study and archival. Materials desired by SCP-1942 may 
be introduced into the containment area at O5 discretion. 


Description: SCP-1942 is a colony of western harvester ants 
(Pogonomyrmex occidentalis), which at any given time consists of 
approximately 85,000 workers and drones and an unknown number 
of queens. SCP-1942 inhabits a single primary nest and six 
secondary nests near [REDACTED]; to date, no other ant colonies 
within the [REDACTED] region have demonstrated properties similar 
to SCP-1942. Attempts to ascertain the depth of SCP-1942's nests, 
or the number of queens in the colony, have failed due to SCP-1942 
acquiring and dismantling all monitoring equipment and miniaturized 
drones. The dietary and reproductive habits of SCP-1942 are typical 
of its species. Average lifespan of an SCP-1942 worker is 
approximately 55% longer than that of a typical P. occidentalis 
worker.
