Movie Myths: Sonar Looks Like An Atari Game

Make a movie in a submarine and, without a doubt, someone will eventually detect something using sonar. And it always looks the same: a circular screen with a dial going clockwise and detecting blips. Simple and basic, it looks like an ’80s Atari game.
Actually, that’s active sonar. It still doesn’t look exactly as presented in the movies, but it basically sends a ping and waits for it to come back. This gives you an idea on the size, speed, and position of whatever the sonar is pinging. However, it also tells everyone around you where you are which is why, most of the times, subs use passive sonar. And as you can see in the photo, that looks a little different.
War Veterans With PTSD Will Eventually Snap

PTSD is without a doubt a troubling issue, and one that affects many soldiers who return from war. They’ve likely seen some pretty bad stuff and have trouble readjusting to life at home. However, it’s a far stretch to consider them ticking time bombs; in fact, that treatment likely only exacerbates their sense of being “out of place.” According to Hollywood, any sudden movement or loud noise is enough to make someone with PTSD have a flashback to the battlefield and start going berserk.
It’s true that people with PTSD can experience flashbacks and angry outbursts. It’s also true that some soldiers have gone on violent rampages after returning from war. However, they are a very small minority. Some of the more common symptoms of PTSD include sleeping problems, depression, and feeling tense or guilty, which are very reasonable responses for anyone after a traumatic event. And reasonableness is seldom Hollywood’s stock and trade.
