    when he said “next up we’re gonna try something a little more difficult, interpreting relationships” i felt that
  • @wermzucker1432
    My brain: "You should know how to analyze bloodstain patterns" Me: "Why?" My brain: "You just gotta"
  • @pitpat2928
    for all the “math is irrelevant irl” jokes, I’ve genuinely wondered for YEARS wtf geometry would be applied to practically, AND YOU’RE TELLING ME THE ANSWER IS CRIME SOLVING??
  • @user-nm8hj7ec7v
    As a forensic science student, blood spatter analysis is totally important in crime scene investigation. The direction of blood flow, angle of origin, the dragging pattern could help you to figure out the condition of victim and perpetrator.
  • @williamvouk2911
    I would’ve appreciated trigonometry so much more if the word problems involved investigating blood stains
  • Guy trying to flirt with me at 2am: "what are you doing up so late?" Me: "learning how to analyze bloodstain patterns hbu?"
  • @elixirology
    I’ve always been interested in forensic investigations but it truly requires so much skill it’s crazy
  • @babytail4725
    Mom: I’m not hitting you that hard why are you crying? The slipper: 4:45
  • @andyshere
    1:40 "So if we used regular whole blood..." My brain: So is it skimmed blood?
  • @gesa7781
    There are two types of people watching this video 1, people who want to know how forensic works 2, people who want to learn how to cover their crime
  • @FSSmash
    Ah yes. 3am youtube recommendations back at it again..
  • @Peluceus
    me watching dexter: oh yeah a blood-splatter analyst sounds like a cool job me hearing this guy talk about triangles, hypotnuses, convergent points and tangents: nevermind I suck at geology
  • @sorin8658
    I like how I refuse to learn basic math, but memorize blood stain patterns at 10pm.
  • As someone interested in criminal justice, psychology, and forensics, this was a really interesting video that will hopefully help me out if I ever take a class relating to blood.
  • @Technocolor00
    one time I woke up with a really bad nosebleed and in my sleepiness I thought I remembered the recommended way to make it stop was to just let it flow so I stood over the sink half awake and by the time I fully woke up and realized what I was doing the bathroom looked like a crime scene
  • @camx8027
    Murderer: Ok let's drag the body here, over there, turn back around, avoid this lil patch of floor and let's put some on the ceiling too This guy: tf happened here
  • @Nepustus
    This guy: shoots a guy on the set in the head The crew: This guy: "so here you can see how the blood splattered on the wall-"
  • @PhillyMar
    I learned a lot watching this. Good skill to learn in the event I decide to switch up my college major.
  • How did anyone not mention how funny it is that the bloodstain pattern analyst is called Steiner
