#Laser (Light Amplification by Stimulated Emission of Radiation)

[dollsahoy]

jokes aside, if you ever see a claim that a common, non-science/tech word is derived from an acronym, there's an extremely high chance that claim is wrong

#and the science/tech acronym words tend not to pronounce the letters in the acronym they way they're pronounced in the words that make it up #pronounce gif however you want #just understand that saying 'the g in graphic is hard' means nothing #laser stands for light amplification by stimulated emission of radiation #and the l and r are the only letters pronounced the same as their origin words

[turts-the-gay]

I JUST FOUND OUT THAT THE WORD LASER IS AN ACRONYM

It stands for Light Amplification by Stimulated Emission of Radiation.

#wtf #how did i not know this #LASER IS A FUCKING ACROCYM #Light Amplification by Stimulated Emission of Radiation #aaaaaaaaahhhhhhhhhhhh

[daytaker]

No one:

Me: Laser pointers… Did they or didn’t they have them in the Devildom whenever Nightbringer happened? Laser is an acronym for something… Lemme check… Ah. ‘Light amplification by stimulated emission of radiation.’ Radiation, huh… Hey, did you ever consider that in the Devildom having no sun means the world isn’t constantly bombarded by solar radiation? Which makes me think, is it bombarded by any cosmic radiation? Where is it situated in the universe? Is it in its own universe? Is “human world” the Devildom/Celestial Realm’s word for the entire universe? Hey… Hey, they have plants in the Devildom, right? Why did plant life evolve in a world without any mechanism for photosynthesis? Is Devildom plant life the result of parallel evolution with earth plant life and the resemblances are just coincidental? How do plants in the Devildom get nutrients? Are they more like animals? Does that mean all animals are technically carnivorous since there are no plants to feed herbivores, only plant-like animals?

WHY AM I LIKE THIS? IT’S A DATING SIM ABOUT CUTE HELL BOYS, SUSPEND YOUR DISBELIEF FOR A FEW MINUTES @daytaker

[ID: A series of images made to look like dialogue from the game Super Lesbian Animal RPG, specifically the characters Harmony and Melody.

Harmony: It's pronounced "Jif".

Melody, looking startled: Huh?

Harmony. Dot Jif, like the peanut butter. The creator said so.

Melody, looking unimpressed: That's dumb. It's "Graphics Interchange Format."

Harmony, looking amused: The "P" in "JPEG" stands for "Photographic." But I bet you don't say "J-pheg."

Melody, looking annoyed: "P" on its own isn't pronounced like "F"! It's totally different!

Harmony: It's exactly the same!

Melody, still annoyed: Name one word that starts with "G" pronounced like "J"!

Harmony, looking smug: Gentrification.

Melody, looking thoughtful: Shoot, should have thought of that. I was just in Brightport.

Harmony, still smug: For your logic to be consistent, you'd have to say "Scub-ah", or "las-eer."

Melody, looking triumphant: Oh yeah?! Well, you'd have to say "J-pej"!

Melody, looking surprised: Wait, "laser" is an acronym?

Harmony: Light Amplification through Stimulated Emission of Radiation.

Melody, looking thoughtful: ...huh. Didn't know that.

Melody, looking annoyed again: You're still wrong, though.

Harmony, looking smug: You just hate me because I'm right.

Melody, still annoyed: I just hate you in general.

Harmony, looking amused: You mean in "gen-eral"?

Melody, looking angry: Ugh! I am "jo-ing" to kill you!

Superman's Early Heat Vision

It's crazy that Superman's heat vision predates the invention of LASERs in 1960. (also, fun fact, it's an acronym for Light Amplification by Stimulated Emission of Radiation).

Before this, it was basically the Microwave Stare (which were invented in 1945), and was claimed to be an "amplification of his X-ray vision"

Here's the first ever use of it, contrary to what Google says was actually Superman #59 (1949) "Superman's Super Man-Hunt!" where it was used to simulate Global Warming.

It's portrayed visually like this later on, and used for property damage and harming women.

Superman uses it rarely, and sometimes cites the concern of irradiating people. However, Superboy spams that shit like he's blinking (which he is). Here's him casually doing Nuclear Fusion with his bare hands.

Theories about Legion's "mini headlamps" (N7 special)

A very happy N7 Day to all of you Mass Effect fans!

Although I still haven't finished Mass Effect 3 (I just haven't been able to pick it up again after the Rannoch arc), I nevertheless wanted to do something special for this occasion, and I thought to myself that I might as well devote a quick study to a subject that's been on my mind for quite a long time: the purpose of Legion's three additional "mini headlamps".

You see, aside from the big, obvious flashlight in the middle, Legion also possesses three smaller lights at the side of their head. Ever since discovering these, I've been wondering what exactly those are for. I've observed that they glow red when Legion is under "stress" (an effect which is unfortunately not present in the Legendary Edition) - or rather, in situations that require a lot of processing power - but as far as their practical function goes, I could only guess. However, going through the ME3 dialogues again, I noticed a small detail which could potentially explain what exactly those small lights are - and in addition, give us a little insight into how Geth perceive the world visually.

Disclaimer: Before going into this, I should mention that I have no technical education in robotics, laser scanning, or any related areas of engineering. I based my conclusions solely on what information I could find on the internet, as well as my own reasoning and observations.

[Potential spoilers for ME3]

LADAR/LiDAR scanning and three-dimensional perception

To start off, what basically led me on this track was this comment by Tali in ME3:

Their AI lets them use extremely detailed ladar pings. Xen's countermeasure overwhelmed them with garbage data.

First off, we need to clarify what exactly ladar is. LADAR, more commonly known as LiDAR, stands for "Light amplification by Stimulated Emission of Radiation detection and ranging" - or, in case of LiDAR, "Light detection and ranging/Light imaging, detection and ranging. It's a method for measuring the distance, speed, and surface structure of objects by the means of laser scanning, usually with beams in the infrared spectrum (there are different wavelengths of light in use, however). Essentially, LiDAR is based on the same principle as the echolocation of bats, the only difference being the use of light instead of sound. Every LiDAR system consists of three integral components: a transmitter, a receiver, and a timer. The transmitter will send out a laser beam, which will be reflected by the object it hits; afterwards, the reflection will be registered by the receiver. Because the speed of light is a known constant, the distance of the object can be deduced by the timer, which will determine the delay between the light impulse being send out and the reflection being captured, also known as "time of flight".

However, because each laser beam only represents the coordinates of a single point, multiple laser beams are necessary to create a detailed 3D map of the environment. Some LiDAR lasers, like those used in automated vehicles, pinwheel to collect data in a 360° radius, generating a 3D image of all objects in the vicinity, including cars, pedestrians, and other obstacles. This results in multiple "points" forming a "point cloud" together, digitally depicting the surroundings on a 3D level. Because each laser emits hundreds of impulses per second, this technology enables you to take highly precise measurements in a very short period of time. LiDAR technology is not only utilized in autonomous driving, but also all kinds of other areas too, like archaeology, topographical mapping, and monitoring of vegetation growth.

Now, with this in mind, my theory is that Legion's small headlamps are the transmitter and receiver components of the LiDAR system - more specifically, I think the transmitters are located on the right, while the singular light on the left is the receiver. However, since we know that normal scanning LiDAR requires multiple laser beams for a detailed 3D image, the question is why Legion would only have two of them implemented. Personally, my suspicion is that the Geth might be using a flash LiDAR: Flash LiDAR is a different type of LiDar emitting a single wide, diverging beam, similar in shape to the beam of a flashlight. By projecting the reflected light onto a sensor array, a flash LiDAR can create a complete 3D environment without the use of multiple impulses. In addition to being very compact, flash LiDAR sensors have no moveable parts, making them extremely resistant to any kind of vibration - an undeniable advantage in all situations that require quick movement, such as combat.

Analysis of atmospheric composition with LiDAR

Still, that doesn't explain why Legion would have an additional transmitter on the right side of their head. We do know, however, that the laser scans with LiDAR are precise enough to not only measure the exact distance between objects, but also analyze the density of particles in the air: Because the molecules in the air cause the light from the laser beam to backscatter, LiDAR is also utilized in monitoring air quality and detecting fine dust, being able to determine traces of atmospheric gases such as ozone, nitrous gases, carbon dioxide, and methane. Depending on the wavelength of light used, the LiDAR system might be more or less precise in measuring molecular backscattering. For that reason, LiDAR systems using multiple wavelengths of light are most efficient in determining the exact size distribution of particles in the air.

With this in mind, let's take a look at Legion's opening line in ME2 upon entering the Heretic station:

Alert. This facility has little air or gravity. Geth require neither.

Going by what I explained above, the reason why Legion was able to tell there is no oxygen in the atmosphere isn't because they have some built-in chemical sensors to analyze the air's components - it's because they can literally "see" the particles in the air.

Thus, I think the second transmitter on the right side of Legion's head might use a different kind of wavelength specifically intended for the detection of atmospheric particles, perhaps in the UV-spectrum (the general rule is that the shorter the wavelength, the higher the resolution of the 3D image is, and since UV has a shorter wavelength than infrared, I imagine it might be used for this purpose). Meanwhile, the big flashlight in the middle might be a photoreceptor, being able to detect "normal" light visible to humans. In addition, the Geth are probably able to see UV-light (since the Quarians are able to see it, it would be logical to assume the Geth are as well), and maybe even infrared and other wavelengths. To summarize the function of all of Legion's headlights, I imagine it works roughly like this:

The two lights on the right side of Legion's head (marked with a red and magenta line) might be LiDAR transmitters, using infrared and UV-light, respectively; the single small light on the left (circled with green) might be the LiDAR sensor/receiver, while the big light in the middle (circled with blue) might be a photoreceptor (Source)

The effect of Xen's countermeasure (and potential means to bypass it)

It might be difficult to imagine from a human point of view, but judging from the information that the Geth use LiDAR as their main method of depth perception, Tali describing Xen's invention as a "flash bang grenade" actually makes a lot of sense: If you're normally able to observe your surroundings down to a molecular level, it would probably feel very disorienting if you're suddenly not, not mention being unable to tell whether an object is far away or close by (which would be absolutely devastating if you suddenly come under attack).

Still, that doesn't mean there are no potential alternatives: Radar, which has been in use longer than LiDAR, is another method to determine the range, angle, and velocity of objects. Due to radar using long-waved micro- and radio waves, the measurements are generally a lot less precise than those with LiDAR; despite this, radar still has its use during inclement weather, when LiDAR systems are very prone to disturbances by dust, mist, and rainfall. Furthermore, LiDAR can only provide measurements up to 200 meters, while radar is more efficient at greater distances. In fact, most modern autonomous driving vehicles work both with LiDAR and radar, in addition to a conventional camera (the only vehicles that don't use LiDAR are those from Tesla, which have a reputation of being unsafe). So, it's only reasonable to assume that the Geth don't rely on LiDAR alone, but use various technologies in combination with it to compensate for each one's weaknesses.

Interestingly, a type of 4D radar is currently in development, intended to be used in autonomous driving. It provides 3D images with a similar resolution as LiDAR, at a potentially much cheaper cost. Still, whether LiDAR or 4D radar is the better choice for autonomous driving is still a heatedly debated question, and only time will tell which of both systems comes out on top. Nevertheless, assuming Xen's "flash bang grenade" only targets the Geth's LiDAR sensors, I wonder if they could've potentially found a way to adapt and bypass it, given enough time.

Anyway, that's the material for a different kind of analysis - for now, I hope you enjoyed this little deep dive into the science behind the Geth. Thank you all for reading and have a nice N7 Day! :-)

The word “laser” is an acronym, coined in 1959, standing for Light Amplification by Stimulated Emission of Radiation. The word “taser”, coined in 1970 and originally a brand name, is also an acronym, inspired by the earlier “laser”, but it stands for “Thomas A. Swift’s Electric Rifle” after a 1910 kids’ adventure book about a boy inventor that created a gun that fired electricity.

Did you know that LASERS are called LASERS because “LASER” is an acronym for “Light Amplification by Stimulated Emission of Radiation”? Not many people know this, but lasers were actually invented by an evil sorcerer. Not many people know that. Furthermore, the evil sorcerer in question, also happened to have 12 different titties that went vertically down the front of their torso like what rats have. Not many people are aware of that fact. They have 6 on the left and 6 on the right, which accounts for 12 titties in total. Because 6 plus six equals Twelve (12). Not many people know this.

The “lazer” in your name is misspelled. Laser is an acronym (Light Amplification by Stimulated Emission of Radiation).

But maybe you did it on purpose so idk. I just wanted to point that out cause it dealt me some Psychic damage

I didn't do that on purpose but I'm leaving it since it bothered someone. It's like the Z in Bratz

Hi there! A question, I'm kinda new to the Word of Honor fandom, and I've seen the acronym "CP fans" or "CPF" being thrown around when talking about ZZH and GJ, but I'm absolutely lost as to what it means (also english is not my native language so it might be because of that?) do you you what it means and if so, could you tell me?? thank you in advance!!

Hi! No problem, here are some primers for terms on this blog:

CP: "Couple" - A couple usually in a fictionalized romance in a show or movie. I.e. The CP of Word of Honor is Wen Kexing and Zhou Zishu (WenZhou). The IRL CP is Gong Jun and Zhang Zhehan (JunZhe)

JunZhe / LLD: Langlangding refers to the ship of Gong Jun and Zhang Zhehan

CPF: CP fan - couple fan, they're basically fans who ship the actors as real couples.

Candy: an unconfirmed tidbit of a happening between the CP. It could be a photo, audio clip, rumor, story, observation, or kadian.

Kadian: a numerical code used as shorthand to communicate a message. This is often used on 5/20, May 20, because in Mandarin it sounds like I love you. These common shorthand codes may be similar to English acronyms, which are letters that stand for a specific phrase. For example, LASER actually stands for "light amplification by the stimulated emission of radiation.”

Kadian is often used in time stamps because it's convenient and easy. Many companies use kadian like 51129 to advertise products to the JunZhe/WOH/SHL fandom. 5/11 = ZZH's birthday. 11/29 = GJ's birthday.

I'll add more as I see it come up. Thank you for the question!
