ive been doing alot of snooping around test shaft 09, so ill keep this updated with what i find
-Test Shaft 09 was condemned on June 5th, 1961, due to Cosmic Ray Spallation, which, strangely enough, was discovered by accident in the 1970's http//en.wikipedia.org/wiki/Cosmic_ray_spallation
-the borealis is a possible reference to Project Rainbow, or the Philadelphia Experiment http//en.wikipedia.org/wiki/Philadelphia_Experiment
-i noticed an odd symbol on one of the large pillars in the beginning of the level that i have not seen anywhere else in the game http//steamcommunity.com/id/trunk_slamchest/screenshot/540640198853882445
-there are two scientists referenced in Test Shaft 09 Robert Bunsen (inventor of spectroscopy), and Johannes Kepler (creator of the laws of planetary motion). both scientists hail from Germany.
-pump station alpha has a sticker that has "photofabrication" on it. Photofabrication is the photographic method of manufacturing integrated circuits in which a pattern is placed over a semiconductor in an etching solution and exposed to light. This could suggest that replusion gel was used to make circuit boards, and sub-sequentially that silicon is used in replusion gel; and/or that Aperture was producing micro-processors as early as 1953.
-the first testing chamber that introduces the replusion gel, has a large "Did you Know...?" poster about the repulsion gel. the fine print at the bottom suggests that Aperture was being sued by consumers for their miss use of the gel, which was discontinued shorty after http//steamcommunity.com/id/trunk_slamchest/screenshot/540640198862636569?tab=public
-CJ states that the testing spheres are made of asbestos. this could explain the large amount of hazardous waste at the bottom of the test shaft
-CJ mentions a control group of Kepler-Seven with implanted brain chips reaching 500 degrees at the beginning of test chamber 3. here is what i found about Kepler-7 http//en.wikipedia.org/wiki/Kepler-7 . Kepler is also a crater on the moon, and mars. It is also interesting to note that the test numbers jump to from 3 in the previous chamber, to 27 in the same chamber CJ mentions the control group. December 27th, 1571 is the day Johannes Kepler was born, and December 27th, 1968 was the day that the Apollo 8 command module splashed into the Pacific Ocean, ending the 1st manned mission to the moon.
-after CJ mentions "this next test has trace amounts of time travel..." he begins complaining about how much time the player is taking on the catwalks, and after completing the final test(#28, 1958) in the chamber, CJ seems to get upset, and fire one of his employees. who did CJ fire? he also recommends that the employee should "invent a special door that wont hit you in the butt on your way out."
-after completing the third testing sphere, CJ's pre-recorded message about "olympians, astronauts and/or war heros" is abruptly cut short, and then informs the player that the elevator is not a bathroom, possibly insinuating that the player is taking a long time to enter the elevator. it should be noted how peculiar the interruption is (it sounds as though CJ is saying "save the..." before its cut out) and how drastic CJ's voice and attitude changes.
-the number in the "Please take a Number" machine in the test subject waiting room at pump station beta is 426 http//steamcommunity.com/id/trunk_slamchest/screenshot/540640198864671673 this could possibly be a reference to Julius Caesar http//en.wikipedia.org/wiki/426 ; 426 is also a sphenic number; 2 x 3 x 71 = 426.
-the counter above the "Please Take A Number" machine reads 023, or 823 considering the 0 is broken, which conflicts with how many numbers were taken from the machine http//steamcommunity.com/id/trunk_slamchest/screenshot/540640198864639701
-the first appearance of the "Alert Your Supervisor If You See..." posters are at pump station beta. Pump station beta is also the first and only time CJ mentions Black Mesa, or the 1968 senate hearings on missing astronauts in his pre recorded messages. this raises my curiosity, as the Apollo Program's missions to the moon took place from 1961 to 1975. it is also indicated that Pump Station Beta was constructed in 1971.
-there are 9 testing spheres in shaft 09, according to the map at the beginning of the shaft. the player only plays through 6 spheres, presumably leaving 3 unaccounted for. there are also 6 random spheres floating in the hazardous waste when the player first enters the main shaft.
-i noticed 3 vitrified doors in the entire shaft have B 09/S on them. no other vitrified door has this. the first one leads to first entrance to aperture, built in 1952; the second door, when activated, triggers the CJ message stating "We're going to have a super conductor pointed at you and turned up to full blast on the next test..."; and the third is the door that is blown off its hinges, leading to the Borealis dry dock.
