WEBVTT 00:00:00.000 --> 00:00:02.259 So today we are doing something totally different. 00:00:02.480 --> 00:00:04.459 We are throwing the usual flavor completely out 00:00:04.459 --> 00:00:07.459 the window. We really are. It's a bit of a departure 00:00:07.459 --> 00:00:10.199 for us. Yeah, because we aren't tackling like 00:00:10.199 --> 00:00:13.619 a 500 page biography today. Yeah. And we aren't 00:00:13.619 --> 00:00:16.480 dissecting some dense peer reviewed scientific 00:00:16.480 --> 00:00:18.339 journal either. No, we are looking at something 00:00:18.339 --> 00:00:20.870 much, much shorter. Right. Our source material 00:00:20.870 --> 00:00:24.969 for this deep dive is literally a single Wikipedia 00:00:24.969 --> 00:00:27.649 disambiguation page. Just a list of links, basically. 00:00:27.789 --> 00:00:31.429 Exactly. Four letters. One word, SLAM. S -L -A 00:00:31.429 --> 00:00:35.950 -M. Okay, let's unpack this because while SLAM 00:00:35.950 --> 00:00:38.929 sounds like the simplest, most basic physical 00:00:38.929 --> 00:00:40.649 action you can think of. Like shutting a door 00:00:40.649 --> 00:00:42.369 in a hurry, right? Yeah, yeah, exactly. Just 00:00:42.369 --> 00:00:44.929 slamming a door. But the source material reveals 00:00:44.929 --> 00:00:47.549 that it is actually this incredible linguistic 00:00:47.549 --> 00:00:51.450 chameleon. This one single page maps out a bizarre 00:00:51.450 --> 00:00:54.609 web covering everything from human biology and 00:00:54.609 --> 00:00:57.750 like cutting -edge software to literal weapons 00:00:57.750 --> 00:01:00.649 of war. What's fascinating here is how this single 00:01:00.649 --> 00:01:03.119 document which is essentially just a list of 00:01:03.119 --> 00:01:04.799 definitions to help you navigate a website, right? 00:01:04.980 --> 00:01:07.739 It serves as a complete cross -section of human 00:01:07.739 --> 00:01:10.560 invention. Oh, totally. I mean, we use the exact 00:01:10.560 --> 00:01:14.299 same four letters to describe raw emotional art, 00:01:14.579 --> 00:01:17.000 highly complex and visible computing architectures, 00:01:17.280 --> 00:01:20.019 and the mechanisms of geopolitics. We demand 00:01:20.019 --> 00:01:22.379 a massive amount of utility from this one syllable. 00:01:22.640 --> 00:01:25.140 And that is exactly our mission today. We are 00:01:25.140 --> 00:01:27.799 going to map out this surprising kind of hidden 00:01:27.799 --> 00:01:31.900 architecture behind the single word. And I promise 00:01:31.900 --> 00:01:33.620 you, to everyone listening, by the end of this 00:01:33.620 --> 00:01:35.420 deep dive, you are going to have an entirely 00:01:35.420 --> 00:01:38.840 new appreciation for how we name the world around 00:01:38.840 --> 00:01:41.140 you. I think the most logical place to start 00:01:41.140 --> 00:01:45.019 is with the most intuitive interpretation of 00:01:45.019 --> 00:01:47.019 the word. The physical stuff. Right. When you 00:01:47.019 --> 00:01:49.819 hear slam, your brain immediately goes to physicality, 00:01:49.959 --> 00:01:54.079 to rhythm, to raw human expression. That primal 00:01:54.079 --> 00:01:56.719 energy is the foundation and we see it perfectly 00:01:56.719 --> 00:01:59.519 reflected in how the word is harnessed in Culture 00:01:59.519 --> 00:02:01.879 in the arcs the cultural pulse of this word is 00:02:01.879 --> 00:02:04.340 just undeniable like you've got slam dancing 00:02:04.340 --> 00:02:06.859 Which is an entire style of dance built around 00:02:06.859 --> 00:02:09.539 intense physical collision in a crowd visceral 00:02:09.610 --> 00:02:11.969 Yeah, and then you have slam death metal, which 00:02:11.969 --> 00:02:14.389 is this subgenre of death metal known for being 00:02:14.389 --> 00:02:18.430 incredibly heavy, aggressive, and frankly, completely 00:02:18.430 --> 00:02:21.310 uncompromising. There is even a DJ and electronic 00:02:21.310 --> 00:02:24.169 music production duo from Glasgow who just call 00:02:24.169 --> 00:02:27.479 themselves simply slam. See, that makes sense 00:02:27.479 --> 00:02:29.479 to me. The thread connecting all those examples 00:02:29.479 --> 00:02:32.560 is just visceral intensity. Exactly. It is music 00:02:32.560 --> 00:02:34.479 and movement that you physically feel in your 00:02:34.479 --> 00:02:38.620 chest. But the brilliance of looking at a disambiguation 00:02:38.620 --> 00:02:41.699 page is the immediate, jarring contrast you find. 00:02:41.900 --> 00:02:44.159 Oh, yeah. The whiplash is real. Because right 00:02:44.159 --> 00:02:46.819 alongside that intense, heavy, abrasive culture, 00:02:47.180 --> 00:02:49.860 we find out that Slam is also the title of a 00:02:49.860 --> 00:02:53.719 2002 pop song by the 18s. Wait, the 18s? From 00:02:53.719 --> 00:02:56.229 their album, Pop Till You Drop. Right. That's 00:02:56.229 --> 00:02:59.289 the one. Amazing. And it's also a 2009 track 00:02:59.289 --> 00:03:01.729 by the artist Anna Arbeu from an album called 00:03:01.729 --> 00:03:05.310 Just a Pretty Face. Wow. So this same exact word 00:03:05.310 --> 00:03:07.370 is doing the heavy lifting for aggressive death 00:03:07.370 --> 00:03:09.969 metal and simultaneously serving as the catchy 00:03:09.969 --> 00:03:12.909 upbeat hook for early 2000s teen pop music. It's 00:03:12.909 --> 00:03:14.750 doing double duty. Here's where it gets really 00:03:14.750 --> 00:03:16.430 interesting, though. I was looking at the spread, 00:03:16.710 --> 00:03:20.469 the 18s, the death metal, the DJ duo, and it 00:03:20.469 --> 00:03:24.659 hit me. Slam. is essentially the linguistic equivalent 00:03:24.659 --> 00:03:27.699 of a percussion instrument. A percussion instrument. 00:03:28.099 --> 00:03:30.060 How do you mean? Well, think about the function 00:03:30.060 --> 00:03:31.840 of a snare drum. It cuts through the melody, 00:03:32.120 --> 00:03:34.360 right? It commands your attention. Whether it 00:03:34.360 --> 00:03:38.219 is the gritty, iconic hip -hop of Onyx's 1993 00:03:38.219 --> 00:03:41.759 song, Slam, or a completely different medium, 00:03:41.780 --> 00:03:44.599 like the spoken word stage, the word is universally 00:03:44.599 --> 00:03:47.580 used to just cut through all the noise. I see 00:03:47.580 --> 00:03:49.180 what you're saying. Yeah, and the source material 00:03:49.180 --> 00:03:51.620 highlights the poetry slam. I mean, this isn't 00:03:51.620 --> 00:03:53.719 quiet, sit in a library, snap your fingers kind 00:03:53.719 --> 00:03:56.539 of poetry. No, not at all. A poetry slam is a 00:03:56.539 --> 00:03:59.120 highly performative competition. The audience 00:03:59.120 --> 00:04:00.780 is involved. There are time limits. There are 00:04:00.780 --> 00:04:03.680 judges reacting in real time. It's loud. Very. 00:04:04.039 --> 00:04:06.219 It was designed to break poetry out of those 00:04:06.219 --> 00:04:08.139 stuffy academic halls and really give it a pulse. 00:04:08.699 --> 00:04:11.340 And there's even a 1998 American film literally 00:04:11.340 --> 00:04:13.900 just called Slam starring Saul Williams that 00:04:13.900 --> 00:04:17.050 explores that whole spoken word world. Exactly. 00:04:17.230 --> 00:04:19.529 It demands the listener's immediate attention. 00:04:19.870 --> 00:04:22.410 And we see that urgency translate perfectly into 00:04:22.410 --> 00:04:24.889 activism, too. Right. The Australian rally. Yeah. 00:04:25.310 --> 00:04:27.730 In 2010, there was a major rally in Melbourne, 00:04:27.730 --> 00:04:30.509 Australia. They needed to make a really strong 00:04:30.509 --> 00:04:33.250 statement about licensing laws, and they needed 00:04:33.250 --> 00:04:35.889 to be heard immediately. So they organized under 00:04:35.889 --> 00:04:41.350 the acronym SLAM. SLAM, Save Live Australian 00:04:41.350 --> 00:04:44.009 Music. It punches right through the bureaucratic 00:04:44.009 --> 00:04:46.889 noise, doesn't it? It really does. Across completely 00:04:46.889 --> 00:04:49.529 opposite genres, from death metal to teen pop, 00:04:50.089 --> 00:04:52.529 from poetry competitions to Australian music 00:04:52.529 --> 00:04:56.329 activism, SLAM consistently represents live, 00:04:56.629 --> 00:04:59.339 unapologetic expression. It is never passive. 00:04:59.560 --> 00:05:02.240 Never. And that visceral cultural impact naturally 00:05:02.240 --> 00:05:04.279 translates into the physical stakes of sports, 00:05:04.579 --> 00:05:06.740 which honestly then becomes the perfect engine 00:05:06.740 --> 00:05:09.000 for literature and storytelling. The sports connection 00:05:09.000 --> 00:05:11.339 is huge. Yeah. In the realm of sports, you have 00:05:11.339 --> 00:05:13.339 the body slam in professional wrestling, just 00:05:13.339 --> 00:05:15.639 pure kinetic physicality. You have the grand 00:05:15.639 --> 00:05:18.040 slam in baseball, which, you know, isn't a physical 00:05:18.040 --> 00:05:20.300 collision between people, but it's a massive, 00:05:20.459 --> 00:05:22.720 game -changing momentum shift. There is also 00:05:22.720 --> 00:05:25.040 the Chennai slam, which is an Indian basketball 00:05:25.040 --> 00:05:28.850 team. And of course, the major basketball publication, 00:05:29.490 --> 00:05:32.310 which is appropriately named Slam Magazine. Right, 00:05:32.509 --> 00:05:34.649 because basketball is fundamentally about that 00:05:34.649 --> 00:05:37.730 kinetic energy. The squeak of the shoes, the 00:05:37.730 --> 00:05:40.050 physical impact of the dunk. It's a very rhythmic 00:05:40.050 --> 00:05:43.350 sport. Exactly. But what caught my eye in the 00:05:43.350 --> 00:05:46.610 source material is how creators take that sports 00:05:46.610 --> 00:05:49.670 energy and bleed it into fiction. We have a novel 00:05:49.670 --> 00:05:52.569 by Walter Dean Myers simply called Slam with 00:05:52.569 --> 00:05:55.389 an exclamation point about a high school basketball 00:05:55.389 --> 00:05:57.649 star from Harlem. Oh, right. And then there's 00:05:57.649 --> 00:06:00.290 another novel also called Slam by Nick Hornby, 00:06:00.509 --> 00:06:03.889 which was later adapted into a 2016 Italian film. 00:06:04.329 --> 00:06:07.769 plus a 2018 Australian feature film called Slam, 00:06:08.209 --> 00:06:10.389 directed by Parthosan Gupta. And don't forget 00:06:10.389 --> 00:06:13.649 the animated world. We have Slam Tasmanian, literally 00:06:13.649 --> 00:06:16.870 a cartoon character in the series, Lunatics Unleashed. 00:06:17.209 --> 00:06:18.769 OK, I have to push back a little here, or at 00:06:18.769 --> 00:06:20.829 least ask you to evaluate this. Sure. Looking 00:06:20.829 --> 00:06:23.009 at all these books, movies, characters, is the 00:06:23.009 --> 00:06:25.649 word Slam just kind of a lazy literary shortcut? 00:06:25.930 --> 00:06:28.129 Well, yeah, it feels like whether we're talking 00:06:28.129 --> 00:06:30.610 about a gritty Harlem basketball game, an Australian 00:06:30.610 --> 00:06:33.670 feature film, or some cartoon Tasmanian devil 00:06:33.670 --> 00:06:36.449 spinning out of control, creators just slap the 00:06:36.449 --> 00:06:38.649 word slam on the cover because they want you, 00:06:38.730 --> 00:06:41.149 the listener, to instantly feel the momentum 00:06:41.149 --> 00:06:43.569 without them having to actually earn it through 00:06:43.569 --> 00:06:46.550 the writing. If we connect this to the bigger 00:06:46.550 --> 00:06:49.029 picture, I wouldn't call it lazy at all. I would 00:06:49.029 --> 00:06:51.189 call it a psychological anchor. Okay, psychological 00:06:51.189 --> 00:06:54.470 anchor. Yeah. Humans use language to simulate 00:06:54.470 --> 00:06:57.610 kinetic energy in the mind. A creator doesn't 00:06:57.610 --> 00:06:59.370 have to write a three -page prologue explaining 00:06:59.370 --> 00:07:01.889 that a character is intense or that a situation 00:07:01.889 --> 00:07:05.069 is high stakes. They use SLAM as a signifier, 00:07:05.389 --> 00:07:07.250 and your brain does all the heavy lifting to 00:07:07.250 --> 00:07:09.569 set the tone. It's highly efficient. So it's 00:07:09.569 --> 00:07:12.069 like a mental shortcut for heavy impact. Precisely. 00:07:12.170 --> 00:07:14.250 And we see how deep that psychological anchor 00:07:14.250 --> 00:07:16.350 goes when we look at non -physical games, too. 00:07:16.490 --> 00:07:18.910 Like what? Like in Contract Bridge. It's a card 00:07:18.910 --> 00:07:21.970 game. And a slam is a contract where a player 00:07:21.970 --> 00:07:25.250 undertakes to win all the tricks. Now, there's 00:07:25.250 --> 00:07:27.410 absolutely nothing physically colliding when 00:07:27.410 --> 00:07:29.449 you sit around a table playing cards. Right. 00:07:29.490 --> 00:07:31.610 Nobody's jumping off the top rope through a folding 00:07:31.610 --> 00:07:35.170 table. Exactly. But it is called a slam because 00:07:35.170 --> 00:07:38.769 winning every single trick feels like a definitive, 00:07:39.129 --> 00:07:42.949 heavy, inescapable victory. It carries the exact 00:07:42.949 --> 00:07:46.050 same psychological weight as a body slam in wrestling, 00:07:46.449 --> 00:07:48.529 just translated into a completely different domain. 00:07:49.129 --> 00:07:53.470 Wow. Okay, so if slam communicates high stakes, 00:07:53.829 --> 00:07:56.170 inescapable victories, and this kinetic impact 00:07:56.170 --> 00:07:59.319 in fiction and sports and card games... What 00:07:59.319 --> 00:08:01.639 happens when the military needs an acronym? Oh, 00:08:01.759 --> 00:08:03.660 this is where it gets dark. Because transitioning 00:08:03.660 --> 00:08:06.899 from fictional stakes to literal life and death 00:08:06.899 --> 00:08:09.019 engineering is where this deep dive gets kind 00:08:09.019 --> 00:08:11.480 of staggering. It is a stark pivot. Right. When 00:08:11.480 --> 00:08:13.420 we look at military technology on this page, 00:08:13.620 --> 00:08:16.290 the acronym SLAM is everywhere. We go straight 00:08:16.290 --> 00:08:19.009 from poetry competitions to the selectable lightweight 00:08:19.009 --> 00:08:21.750 attack munition, which is exactly like what does 00:08:21.750 --> 00:08:24.350 that do? It's a small United States multipurpose 00:08:24.350 --> 00:08:26.970 landmine designed to be versatile, primarily 00:08:26.970 --> 00:08:29.689 used by special operations forces to target vehicles. 00:08:29.829 --> 00:08:33.710 And the acronym is SLAM. Correct. Then you have 00:08:33.710 --> 00:08:35.889 the standoff land attack missile. This is an 00:08:35.889 --> 00:08:38.289 over the horizon all weather cruise missile developed 00:08:38.289 --> 00:08:43.100 in the late 1990s. Also SLAM. Yes. And. There 00:08:43.100 --> 00:08:45.740 is the submarine -launched air flight missile, 00:08:46.379 --> 00:08:49.000 an experimental variant of the British blowpipe 00:08:49.000 --> 00:08:51.799 missile system. It just keeps going. It does. 00:08:52.080 --> 00:08:53.960 Even weapons that never saw the light of day, 00:08:54.039 --> 00:08:56.679 like the shoulder -launched anti -aircraft missile, 00:08:56.740 --> 00:08:59.500 which was a competing design proposal that ultimately 00:08:59.500 --> 00:09:02.679 got rejected in favor of the FIM -43 Red Eye. 00:09:02.879 --> 00:09:05.759 You know, reading through that specific list 00:09:05.759 --> 00:09:08.279 of weapons and the source material, I couldn't 00:09:08.279 --> 00:09:11.139 shake this one analogy. What's that? these military 00:09:11.139 --> 00:09:13.960 acronyms feel like reverse engineered branding. 00:09:14.080 --> 00:09:15.759 Oh, I think you're onto something there. Break 00:09:15.759 --> 00:09:18.259 that down. Well, it's as if the defense contractor 00:09:18.259 --> 00:09:21.419 sat in a boardroom and picked the punchy, intimidating 00:09:21.419 --> 00:09:25.179 word, slam, first. They knew it sounded aggressive. 00:09:25.399 --> 00:09:27.419 They knew it carried that psychological anchor 00:09:27.419 --> 00:09:29.460 of a definitive victory we were just talking 00:09:29.460 --> 00:09:31.559 about. Right. And then they turned to the poor 00:09:31.559 --> 00:09:33.840 engineers and forced them to make the science 00:09:33.840 --> 00:09:37.600 fit those four letters. I mean, selectable lightweight 00:09:37.600 --> 00:09:40.600 attack munition. That is almost too perfect. 00:09:41.000 --> 00:09:43.759 You can easily imagine some executives stretching 00:09:43.759 --> 00:09:47.639 the terminology, maybe... swapping out specific 00:09:47.639 --> 00:09:50.179 for selectable just to make sure the final product 00:09:50.179 --> 00:09:53.240 gets to be called a slam. That is a very realistic 00:09:53.240 --> 00:09:55.519 assessment of how military programs are marketed, 00:09:55.940 --> 00:09:58.100 honestly, both to the public and to the congressional 00:09:58.100 --> 00:10:00.399 committees that are funding them. The word isn't 00:10:00.399 --> 00:10:04.379 just descriptive. It is an active tool for military 00:10:04.379 --> 00:10:07.289 deterrence. It is meant to sound absolute. And 00:10:07.289 --> 00:10:09.409 it's so effective that it bleeds right back into 00:10:09.409 --> 00:10:11.509 fictional military worlds, too. Oh, absolutely. 00:10:11.610 --> 00:10:13.870 Like in the G .I. Joe universe, there is a fictional 00:10:13.870 --> 00:10:16.830 weapon called SLAM, which stands for Strategic 00:10:16.830 --> 00:10:19.370 Long Range Artillery Machine. Of course it does. 00:10:19.649 --> 00:10:22.169 And in the video game Tom Clancy's End War, there 00:10:22.169 --> 00:10:24.929 is a fictional anti -ballistic missile system 00:10:24.929 --> 00:10:28.450 called SLAM Spaceland Air Missile Shield. It's 00:10:28.450 --> 00:10:32.049 a total feedback loop. Fiction imitates reality, 00:10:32.549 --> 00:10:34.909 which is already imitating the linguistic tropes 00:10:34.909 --> 00:10:38.049 of fiction. The word becomes completely entangled 00:10:38.049 --> 00:10:40.210 with the concept of destruction and defense. 00:10:46.409 --> 00:10:49.049 We don't just stop at blowing things up. We immediately 00:10:49.049 --> 00:10:52.690 pivot to mapping, creation, and what I like to 00:10:52.690 --> 00:10:55.129 call invisible architecture. It's a great pivot. 00:10:55.330 --> 00:10:59.090 The word SLAM takes on incredibly complex, constructive 00:10:59.090 --> 00:11:01.610 meanings in the realms of science and technology. 00:11:01.929 --> 00:11:03.830 This is where the acronym stops being about brute 00:11:03.830 --> 00:11:06.210 force and starts being about high -level processing. 00:11:06.809 --> 00:11:08.990 In the field of robotics and computing, SLAM 00:11:08.990 --> 00:11:12.009 stands for simultaneous localization and mapping. 00:11:12.190 --> 00:11:14.309 OK, let's pause right there. So what does this 00:11:14.309 --> 00:11:16.330 all mean for you, the listener? Let's bring this 00:11:16.330 --> 00:11:17.889 right into your living room. Yeah, let's ground 00:11:17.889 --> 00:11:20.809 it. The exact same word used to describe jumping 00:11:20.809 --> 00:11:23.649 into a sweat -soaked mosh pit at a death metal 00:11:23.649 --> 00:11:27.269 concert is the exact acronym used by the little 00:11:27.269 --> 00:11:29.529 robot vacuum navigating your house right now. 00:11:29.809 --> 00:11:32.649 It's a beautiful contrast. One is sheer human 00:11:32.649 --> 00:11:35.809 chaos, and the other is precise algorithmic order. 00:11:37.340 --> 00:11:40.039 But to really appreciate it, you have to understand 00:11:40.039 --> 00:11:43.639 how simultaneous localization and mapping actually 00:11:43.639 --> 00:11:46.700 works. It solves a fundamental chicken and egg 00:11:46.700 --> 00:11:49.639 problem in robotics. Right, because if you drop 00:11:49.639 --> 00:11:52.840 a robot into an unknown room, it needs a map 00:11:52.840 --> 00:11:55.200 to know where it is, but it needs to know where 00:11:55.200 --> 00:11:57.980 it is to draw the map. Exactly. Imagine walking 00:11:57.980 --> 00:11:59.740 into a pitch -black room you've never been in 00:11:59.740 --> 00:12:01.740 before. You reach out and touch a wall that's 00:12:01.740 --> 00:12:03.639 mapping. Makes sense. But to know where that 00:12:03.639 --> 00:12:05.740 wall is in relation to the door, you have to 00:12:05.740 --> 00:12:07.580 keep track of how many steps you've taken, and 00:12:07.580 --> 00:12:10.279 that's localization. Doing both at the exact 00:12:10.279 --> 00:12:12.580 same time, constantly updating your position 00:12:12.580 --> 00:12:15.000 while drawing the boundaries of the room, requires 00:12:15.000 --> 00:12:18.279 incredibly complex math and sensor data. That 00:12:18.279 --> 00:12:20.500 is the SLAM algorithm. And it's so important 00:12:20.500 --> 00:12:23.440 that Microsoft even has a dedicated SLAM research 00:12:23.440 --> 00:12:26.480 project to push the boundaries of the spatial 00:12:26.480 --> 00:12:28.659 computing. It's foundational to modern robotics. 00:12:28.899 --> 00:12:30.799 There's also a programming simulation language 00:12:30.799 --> 00:12:33.259 called the simulation language for analog modeling, 00:12:34.039 --> 00:12:36.379 which the source notes is based on older languages 00:12:36.379 --> 00:12:39.139 like Fortran and CASP. And the complexity doesn't 00:12:39.139 --> 00:12:41.779 stop at algorithms. The source material also 00:12:41.779 --> 00:12:44.610 points us to deep level cybersecurity. There 00:12:44.610 --> 00:12:47.470 is a variant of the SpectreBHI vulnerability 00:12:47.470 --> 00:12:51.070 called Spectre based on linear address masking, 00:12:51.750 --> 00:12:53.990 which they shortened to SLAM. Now, a masking 00:12:53.990 --> 00:12:56.009 vulnerability sounds like something straight 00:12:56.009 --> 00:12:58.409 out of a spy movie. How does that actually work? 00:12:58.830 --> 00:13:01.110 To put it simply, modern computer processors 00:13:01.110 --> 00:13:03.110 try to guess what you're going to do next to 00:13:03.110 --> 00:13:06.370 save time. This is called speculative execution. 00:13:07.009 --> 00:13:09.250 Okay. Linear address masking is a feature meant 00:13:09.250 --> 00:13:12.139 to help manage computer memory safely. But this 00:13:12.139 --> 00:13:15.080 specific slam vulnerability tricks the processor 00:13:15.080 --> 00:13:18.139 during that guessing phase. It essentially bypasses 00:13:18.139 --> 00:13:20.559 the security mask, tricking the computer into 00:13:20.559 --> 00:13:23.080 revealing secret data like passwords that it 00:13:23.080 --> 00:13:25.279 was supposed to be keeping secure. So we go from 00:13:25.279 --> 00:13:28.840 a basketball magazine to the deepest, most invisible 00:13:28.840 --> 00:13:31.179 vulnerabilities in computer processing architecture. 00:13:31.519 --> 00:13:33.779 This raises an important question, I think, about 00:13:33.779 --> 00:13:36.590 how we process information. We take a simple, 00:13:36.830 --> 00:13:40.309 aggressive, one -syllable signifier, SLAM, and 00:13:40.309 --> 00:13:43.009 we use it to package highly complex abstract 00:13:43.009 --> 00:13:46.230 concepts. Right, because SPECTR, based on linear 00:13:46.230 --> 00:13:48.769 address masking, is a mouthful. SLAM is easy 00:13:48.769 --> 00:13:51.190 to remember. It makes the invisible feel tangible. 00:13:51.330 --> 00:13:53.970 We do the exact same thing in biology, too. The 00:13:53.970 --> 00:13:56.309 source material lists an acronym for the signaling 00:13:56.309 --> 00:13:58.950 lymphocytic activation molecule. Okay, break 00:13:58.950 --> 00:14:01.350 that one down for us. Well, lymphocytes are white 00:14:01.350 --> 00:14:04.500 blood cells. basically the soldiers of your immune 00:14:04.500 --> 00:14:06.659 system. But they don't just attack anything. 00:14:06.799 --> 00:14:08.559 They need to be activated. They need a signal. 00:14:08.700 --> 00:14:11.019 So they aren't just rogue agents. Right. The 00:14:11.019 --> 00:14:13.659 signaling lymphocytic activation molecule is 00:14:13.659 --> 00:14:16.200 essentially a family of genes that act as the 00:14:16.200 --> 00:14:18.159 communication network for your immune system, 00:14:18.759 --> 00:14:20.940 telling your cells when to fight off an infection. 00:14:21.210 --> 00:14:23.669 So we are using a word that literally means a 00:14:23.669 --> 00:14:26.850 heavy violent impact to describe the microscopic 00:14:26.850 --> 00:14:29.769 invisible trigger that kickstarts our own biological 00:14:29.769 --> 00:14:32.990 defense systems. That is wild. It's packaging 00:14:32.990 --> 00:14:35.570 complexity into digestibility. And we see this 00:14:35.570 --> 00:14:38.190 utility applied to massive sprawling institutions 00:14:38.190 --> 00:14:42.830 and people too. SLAM is the acronym for the South 00:14:42.830 --> 00:14:46.289 London and Maudsley NHS Foundation Trust, which 00:14:46.289 --> 00:14:48.409 is an entire network of hospitals and mental 00:14:48.409 --> 00:14:51.639 health services in the UK. There's also SLA Marshall, 00:14:51.840 --> 00:14:54.200 who is a brigadier general, a military journalist, 00:14:54.360 --> 00:14:58.279 and a historian. And SLAM is also an Italian 00:14:58.279 --> 00:15:00.480 clothing manufacturer. It really is everywhere. 00:15:00.659 --> 00:15:03.220 Just out of nowhere, you are reading about complex 00:15:03.220 --> 00:15:06.279 immune system genes and cybersecurity vulnerabilities. 00:15:06.740 --> 00:15:09.340 And oh, by the way, it is also a maritime apparel 00:15:09.340 --> 00:15:12.179 company based in Italy. The linguistic elasticity 00:15:12.179 --> 00:15:14.480 of these four letters is truly unparalleled. 00:15:14.580 --> 00:15:16.480 It really is. I mean, we started this deep dive 00:15:16.480 --> 00:15:19.139 looking at a simple list, just a Wikipedia disambiguation. 00:15:19.149 --> 00:15:21.149 page designed to help you find what you're looking 00:15:21.149 --> 00:15:23.850 for but we have gone on a genuinely mind -bending 00:15:23.850 --> 00:15:26.080 journey today. We covered a lot of ground. We 00:15:26.080 --> 00:15:29.639 really did. We have felt the intense performative 00:15:29.639 --> 00:15:32.240 rhythm of the poetry slam and those Australian 00:15:32.240 --> 00:15:35.240 music rallies. We've mapped out the psychological 00:15:35.240 --> 00:15:37.960 stakes of contract bridge and Harlem basketball 00:15:37.960 --> 00:15:41.259 novels. We unpacked the reverse engineered branding 00:15:41.259 --> 00:15:43.940 of modern cruise missiles, and we shrank all 00:15:43.940 --> 00:15:46.600 the way down to the microscopic immune responses 00:15:46.600 --> 00:15:49.600 in our own bloodstream, not to mention the algorithms 00:15:49.600 --> 00:15:51.860 navigating our living room. It's an incredible 00:15:51.860 --> 00:15:54.320 spectrum. And as we wrap up, I want to leave 00:15:54.320 --> 00:15:56.070 you the listener with one. one final thought 00:15:56.070 --> 00:15:58.789 to mull over. Lay it on us. I want to draw on 00:15:58.789 --> 00:16:01.250 one last striking contrast from the source material 00:16:01.250 --> 00:16:03.429 that we haven't even touched on yet. Think about 00:16:03.429 --> 00:16:06.750 the exact same sequence of four letters, S -L 00:16:06.750 --> 00:16:10.850 -A -M. On one hand, this page lists the St. Louis 00:16:10.850 --> 00:16:13.529 Art Museum located in Missouri. Okay. This is 00:16:13.529 --> 00:16:15.649 an institution dedicated entirely to preserving 00:16:15.649 --> 00:16:18.350 human beauty, tracing our cultural history, and 00:16:18.350 --> 00:16:20.009 celebrating our highest creative aspirations. 00:16:20.070 --> 00:16:22.980 A sanctuary for human achievement. Exactly. but 00:16:22.980 --> 00:16:25.779 on that exact same page, sharing the exact same 00:16:25.779 --> 00:16:29.059 four letters, stands the supersonic low -altitude 00:16:29.059 --> 00:16:32.620 missile. Oh. Yeah. This was a terrifyingly ambitious 00:16:32.620 --> 00:16:35.720 1950s project by the U .S. Air Force to create 00:16:35.720 --> 00:16:38.279 a nuclear -powered cruise missile. It was designed 00:16:38.279 --> 00:16:41.039 to fly at low altitudes, dropping nuclear warheads 00:16:41.039 --> 00:16:43.879 in its wake, while the sheer sonic boom and radioactive 00:16:43.879 --> 00:16:46.159 exhaust of its engine would destroy literally 00:16:46.159 --> 00:16:49.059 anything it flew over. That is horrific. It was 00:16:49.059 --> 00:16:52.019 a project designed for unimaginable apocalyptic 00:16:52.019 --> 00:16:55.399 devastation. Both the museum and the doomsday 00:16:55.399 --> 00:16:58.960 weapon are slam. What does it say about humanity 00:16:58.960 --> 00:17:02.019 that the exact same linguistic container perfectly 00:17:02.019 --> 00:17:04.539 holds both our most beautiful creative preservation 00:17:04.539 --> 00:17:07.539 and our ultimate darkest destructive capabilities? 00:17:07.799 --> 00:17:10.099 Wow, that is the perfect question to end on. 00:17:10.140 --> 00:17:11.759 It just goes to show you that the words we use 00:17:11.759 --> 00:17:13.920 every single day are never just words. They are 00:17:13.920 --> 00:17:15.920 containers for everything we are capable of. 00:17:16.200 --> 00:17:17.900 So the next time you hear someone use a punchy 00:17:17.900 --> 00:17:20.119 acronym or you see a title that grabs your attention, 00:17:20.380 --> 00:17:22.859 keep questioning those labels. Keep unpacking 00:17:22.859 --> 00:17:24.859 the language you encounter every day because 00:17:24.859 --> 00:17:27.579 you never know what kind of incredible contradictory 00:17:27.579 --> 00:17:30.259 history is hiding inside just four letters. Thanks 00:17:30.259 --> 00:17:32.119 for joining us on this deep dive. We will see 00:17:32.119 --> 00:17:32.759 you next time.
