  • Crime scene analyst Matthew Steiner teaches the techniques forensics experts use to investigate bloodstain patterns, ranging from easy to difficult. Matthew explains how different types of forces create different bloodstain patterns in the crime scenes, and demonstrates how they can analyze these patterns to figure out how a crime was committed.

    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??

    • @chemieju6305
      @chemieju6305 Před 2 lety +553

      One of the big applications for geometry is any form of 3D computer application. Think about it, you have some information about a 3D object, and then you have to somehow get that onto a 2D screen, complete with colour, shadows, reflections....

      Healthline has a good article titled "therapy for every budget" and it includes free options. Idr if it mentions it but many places have free counseling for youths and other demographics so that's worth checking. Therapy In A Nutshell and NICABM on YT are great, evidence based, understanding, thorough yet accessible, and made by actual therapists (I def recommend watching them regardless of whether you are or aren't getting therapy). And 7 Keys to Safe Trauma Recovery is a great book (might not be the title verbatim but I remember the author was Babette Rothchild).

      Most people if they’re trying to get away with a crime can get stressed, rush and therefore make mistakes. Luckily this is all to do with physics but even despite that, there’s the understanding of human nature such that if someone has time to confuse forensics teams then they probably have time to clean things up. Making a bigger mess would be counterintuitive. so would harming someone so fatally that they’re not able to get themselves help, and hiding it but still

It's amazing how math and physics can be applied to understanding bloodstain patterns in crime scenes. It's like solving a puzzle using trigonometry and geometry to unlock the secrets behind a gruesome story. This just goes to show that math is not only useful in everyday life, but can also be thrilling and intellectually stimulating. Who knew that studying math could be so spine-chillingly exciting!

    When the forensics expert described the individual patterns I knew what the result/cause would be, because I‘ve basically used 90% of them to get color on canvas or textiles… funny that.
