Alright, I read the news every day, and lately there seems to be an unusual amount of mysterious deaths. Just a hunch really. But I'm pretty keen and also paranoid so the fact I haven't had this occur to me before is decent enough of a starting point.

Tried to check missing persons reports for statistics to see if there was a spike, but there's too many problems with sample size and white noise to be able to get a firm read. Missing people naturally go up in the summer time, and there's false reports and double reports and reports that are obviously not murders, such as plane crashes.

So presumably the only option left is to see if there is a connection between certain deaths, but that's tricky too. How do you tell the difference between a crime of passion and a serial killer striking?

Anyway, here are the deaths/disappearances I consider potentially part of the pattern.

Have no idea which board to post this topic on so I decided here would be best

So I have seen several vids on this topic, alot of which claim that cauterizing a wound would somehow increase the risk of infection?

Wouldnt the intense heat caused by the gunpowder effectively sterilize the wound? Wouldnt the thick scarred/burnt skin or whatever prevent shit from getting in and infecting it?

>1) 90% of lecturers can't teach so you're better off learning on your own
>2) if you're learning on your own anyway then what the FUCK is the point of paying thousands of $ a year in tuition fees???
>3) Cafeteria foods absolutely sucks ass and very expensive. Universities can easily make more money if they licensed to proper restaurant and fast food chains rather than "XYZ catering" whose food tastes like horseshit
>3.3) that smart ass who always tells you to cook your own food until you realise you can only afford potatoes and pasta with your budget.
>4) library is always overcrowded as fuck
>5) the books you want to read are never available
>6) said books cost $100 even if used
>7) access to libgen blocked by college security
>8) 90% students speak a different language and hang out with their kind only (especially Asians). But if you want to hang out with them they tell you to go away. Cultural racism is widespread.

What's even worse is that so many students just quietly accept this reality and pay thousands of $ without question

professors/teachers/students,

Tell us about your pet peeves, shit that rustles your jimmies, that students do in your class.

>instruct gen chem at my state uni
>>students ask me to slow down my PowerPoint so they can write every word down (I have the .ppt file on blackboard)
>>that guy who emails me nonstop about concepts not related to topics at hand
>>that guy that comes to office hours every week, makes an effort, we can work together... then drops the course.... quits, gives up, despite having the right drive/mindset (10-15 of these types every semester)
>>to a lesser extent, that guy/girl who doesn't attend class, submits shit work, then wants to contest their 68% D grade a week before we submit final grades. I do feel bad that they wasted $3,600 for my course to not attend and fail tests

What conditions on earth would be necessary for humans to live, say, 800 years? What differences in atmosphere would be necessary? What differences in enviornment overall?

I'm just curious.

a negative number times a negative number should be a negative number

we've gotten this wrong and now it's fucked up the rest of math.

first, think about what something being negative means. it means that it's in a different direction, in the case of traditional negative numbers, the exact opposite direction as the traditional number line.

how do we describe things going in different directions? vectors. what happens when you multiply two vectors going in the same direction? they become a vector that's even stronger in the current direction, they don't change to the opposite one, because that doesn't make any goddamned sense.

this also gets rid of the problem of negative numbers not having square roots.

Where were you when you realized that you shouldn't just think but also think about what you should think about and then use willpower to force yourself to pursue the goals you want to pursue by consciously exploiting the placebo effect by repeating mantras and paradigms related to determination and remembering your consciousness exists and is remembering it exists to yourself to allow your consciousness to expand and become more complex and therefore powerful?

So we're looking for a unified theory of physics to unite Newtonian and quantum mechanics, correct?

How many characters is the formulation of this theory going to be? Why can't we brute force it computationally?

anyway /sci/ can explain wtf sin cos and tan mean? I understand what it is but I don't understand how it works intuitively. I can't find anything regarding the intuitive side of it on YouTube.

What Bio careers are hot and gonna remain hot for a few decades?

Anyone have stories of knowing people making decent cash in an in-demand, cutting-edge biology role?

I'm guessing crossover roles to inform other fields involved in economic and human development are the business.

Hey Guys,
I came here a few days ago, but not sure if I was clear about what I was asking. I'm curious as to which statistical method to use for analysis. Pic related is the format of the test. Here's how it goes:
>subjects are given a survey where they first choose their scenario
>within that scenario, they give a 1-7 rating for factors x,y, and z
>after that, they move on until they encounter one of the scenarios and repeat these steps

Subjects will be doing this probably about 100 times. I imagine comparing means with each subject regarding the scenarios they run into is what's needed, but don't know how to approach the propper analysis.
Also, I may be comparing 2 groups of 20 using this same format for each, how would I analyze it? Your help is much appreciated!
