Modele de pistolet laser inspire de l’emblematique

L’entreprise américaine Lockheed Martin, plus grosse société de défense et de sécurité au monde, travaille sur un canon laser de réglage carabine capable de faire exploser un missile en plein vol à l’aide d’un rayon laser surpuissant. Avant de peut-être décliner cette arme sous un modèle de pistolet laser inspiré du phaser de Star Trek, utilisable sur le champ de bataille.
Certains objets futuristes imaginés dans les films de science-fiction fascinent au point que certains scientifiques tentent de réaliser de véritables répliques. Après avoir reproduit l’Hooverboard de Retour vers le futur et le sabre laser de Star Wars, va-t-on réussir à recréer le phaser de Star Trek, l’emblématique pistolet laser de l’univers fictionnel Star Trek ? L’entreprise Lockheed Martin, géant de l’armement et du dispositif de sécurité, travaille en tout cas à concrétiser ce fantasme qui ferait bondir n’importe quel fan de Star Trek au plafond, rapporte le site Smithsonian.
Lockheed Martin n’est pas la première société à vouloir développer un canon pointeur laser 30000mw capable de causer de sérieux dégâts à une cible mouvante à plusieurs kilomètres à la ronde. En 2015, l’Américain Boeing avait déjà mis au point un prototype équipé d’un faisceau laser d’une puissance de 2 kW capable de détruire un aéronef. L’armée américaine avait quant à elle testé un autre de ces canons embarqué sur un navire de guerre. D’une puissance de 30 kW, invisibles et inaudibles, ces bombardements de photons sont extrêmement précis et surtout très peu chers : un dollar par tir seulement. La chaleur émise est si puissante que l’objet visé s’enflamme et explose en quelques secondes.
Après avoir effectué plusieurs essais concluants sur des missiles en plein vol, l’objectif de Lockheed Martin est dorénavant de réduire la taille de ces machines tout en gardant une force de frappe comparable, voire plus élevée. En effet, les canons lasers les plus puissants requièrent une énorme quantité d’énergie, que seul un générateur de la taille d’une maison peut produire. C’est là que l’idée fleurit. Et s’il était possible de reproduire lephaser de Star Trek, pistolet stylo pointeur laser capable de détruire à peu près n’importe quoi ?
Ron Afzal, l’un des ingénieurs en charge de ce projet, affirme à Smithsonian avoir développé un prototype pouvant être transporté à l’arrière d’une remorque de camion de surveillance. Pas assez petit pour être tenu en main comme un véritable pistolet laser, toute fois. Mais le scientifique est confiant : « Évidemment, il est difficile de prédire le futur. Mais je ne parierai pas contre la science ». Si un prototype de phaser venait à voir le jour, il pourrait notamment servir sur le champ de bataille pour viser des installations ennemies. En revanche, il ne pourrait être utilisé contre des cibles humaines, car les conventions de Genève s’y opposent.

What Do The Protests in Seoul Look Like Now?
This past Friday the Korean Constitutional Court (think of it as the US Supreme Court) ruled unanimously that Park Geun Hye should be officially impeached. Since most of the country wanted this (at her lowest I think she has a 10% approval rating) there were massive celebrations in the streets. There were musicians, free food stalls, and fireworks. Now of course there are plenty of (mostly elderly) people rioting and claiming that this is the end of democracy (when really its just an example of democracy working...) but they are in contained areas surrounded by police. As far as I know 2 people died and many more are injured but its been due to violence by the pro-Park side (for example, the rioters were trying to flip over a police bus and knocked over a speaker which fell and killed an elderly man who was part of the riot...) I walked through the celebration area the day after the announcement if you'd like to take a look and hear the sounds. Skip to 4:20 unless you want to see my friends new cafe opening party haha :) If you could all do me a really big favor: Please give this video a thumbs up on YouTube here. People have been leaving incredibly nasty comments targeting myself and my family (I have deleted and blocked most of them) and this video now has some of the most down-votes I've ever had on a video :/ That would really mean a lot! Thank you ㅠㅠ Korea now has to vote for a new president so that will be starting as we speak :)
The Real Reason for Supernatural Concepts
Remember back in 2013 when Kpop went into full supernatural concept mode? From EXO's Wolf, VIXX's On & On, Boyfriend's Bounce, etc, etc... there were vampires, aliens, werewolves galore. Nowadays in 2016, though, we're seeing a rise to realism. BTS dealing with drugs (I Need U) or Monsta X dealing with totalitarianism (All In) But, why? "Zombies are the perfect metaphor." (source) Basically, using the supernatural has always been a way of talking about real life issues, without actually bringing them up. For example, in Harry Potter House Elves would represent slaves, the discrimination and fear of werewolves represented how ridiculous racism is, etc. Fiction allows us to talk about important issues in a sly way. For example, VIXX's Hyde portrayed them as vampire-like, living in a spooky house and dark forest, growing black wings and almost being taken over by a monster. At its core, this is a song about dangerous relationships. A partner who is emotionally unstable, but charming. Hurting you but begging to have you back. This can be a metaphor for abusive relationships of all kinds. They repeat over and over that "that man isn't me, there is a crazy 'other me' inside of me." Just as abusers usually do after a moment of violent anger. Hiding this message behind the mask of "monsters" and "dark angels" makes it easier to consume and talk about. But take away the supernatural and its a serious issue they bring up. Another great example is Monster by Big Bang. They dress up as literal monsters, but talk about how just because they are different and not fitting into the society's mold they aren't bad people. It's an anthem for misfits, and a message to society to stop being so cruel. So why are we shedding the costumes now? Why are things suddenly more...real? We're done hiding. The problems can no longer stay hidden, we need to talk about them. No more using vampires and ghosts as metaphors, the general public is more comfortable discussing issues like depression, drugs, mental health, discrimination, etc. The move to realism means that we're being realistic about the problems - we're addressing them head on. That being said, there is nothing wrong with supernatural concepts being used to talk about issues! Often people can't understand something in its original form. For example, maybe someone doesn't see the need for LGBTQ+ rights. Give them a love story with a couple that is forced apart, never to be together (perhaps a vampire and a human??) because society says its unnatural. If while reading the story or watching the movie, that person feels upset about this poor couple torn apart by society, maybe they will see the correlation between their belief that gay marriage is wrong. Basically, I think that the constant changing of concept trends is fascinating and it means much more than we think!
I Was Stalked and Filmed on a Subway? :(
Recently I had a very creepy experience on the subway. A had a very odd man sit next to me and start filming me secretly (though obviously not so secretly since I noticed) He also tried to follow me but luckily I tricked him. For more info you can check the video below. **this is not common AT ALL in Korea, it only happened to me in Seoul because that's where I live. This could, and does, happen all over the world no matter what culture~** What I hope you take from this: 1. Be aware of your surroundings at all times. If someone sits next to you (even if it seems totally normal) just take a millisecond to recognize that - don't just stay zoned in on your phone. 2. If you feel uncomfortable - get up and move. I didn't do this but I should have. I didn't need to "prove" he really was creepy, regardless of if he was or not, I have every right to just move away. 3. If someone made you feel uncomfortable, trust your gut and keep an eye on them in some way. If I hadn't noticed him earlier, he might have followed me off the train without me knowing. 4. Let someone know where you are and what was up. Even if its just texting a close friend that is dependable "hey I'm at XYZ bus stop, there was a weird guy on the bus lol" just so someone knows. In case something happens to you, it could help people find you. 5. If you see something weird happening to another girl, try to do something. When I see guys getting too close to girls on crowded trains I always try to make it seem like I'm with the girl too so he's outnumbered, or I stare them down so they know they aren't being sneaky. Be safe out there everyone, and just be alert :)
