About Indeterminate Causality

Indeterminate Causality is a collection of some of my comics, doodles, and sketches. It's a commentary on life, situations we all find ourselves in, the world of medicine, being a guy, and interpersonal interactions, with a slant towards making scenarios as amusing as possible. Updated Monday-Wednesday-Friday (I try, sometimes its difficult with school/exams and such).

So, it's still a difficult subject, but you should be better at it.

Um, that's really not a good way to go about things, we're not going to do it that way.

149 Neurotransmitters

And if you stay out there too long, you'll get sunburned, and have some of these neurotransmitters released! How exciting is that? But you won't know what they're called, and that's ok.

Eye Movements

148 Eye Movements

Did you know if you smack someone hard enough you can actually induce saccadic eye movements? That has nothing to do with anything, and you shouldn't try it because you can hurt someone. But the point is, it's possible.

147 Contraception

Not that THEY would ever NEED it, but they should have it in case their friends need it or something.

Some Fun Stuff of Note

So a couple days ago a classmate of mine sent me a message, totally excited, saying that someone had tweeter her one of my comics. She did not personally know this person, but was acquainted via Twitter and they had felt the need to share my comic with her. This was perhaps the best part of my day. No joke, best part of the day.

Let me explain; I draw these comics for fun, because I like to draw, and because I feel like it. They may not be the best drawings, or the most funny, or whatever, but I enjoy them, and I try to share them with all of you. I have no idea how many people actually follow Indeterminate Causality on a regular basis, but I'm thankful for all of you. Hopefully my work can put a smile on your face, either because it was funny, or because you can't believe I wasted my time drawing something so crappy (hopefully the first one, though haha).

The fact that some person somewhere else was viewing my work is mind blowing to me! That this person enjoyed my comic enough to send it to someone else is absolutely incredible! Thank you, whoever you are!

I'm probably overreacting to this a bit, but whatever. I'm stoked about it. I hope you all continue to enjoy my work as much as I enjoy drawing and posting it.

You all are old enough to make decisions. There are no classes that should be mandatory.

Damn, I gotta be more prepared in class, next time I'll remember a Sharpie.

139 Review

I mean, expecting you to remember anything for an extended period of time is quite unreasonable at this level of learning, right?

Yep, that just happened.

Test Feelings

137 Test Feelings

Now I get worried if I feel too good after a test, but also if I feel too bad about it. There's probably some psychological something or other that's at work here, but we haven't done psych yet, so I don't know what it is. It has me worried.

Drinking Habits

136 Drinking Habits

Whenever a patient says that sort of thing I always wonder, where do they find the time to drink that much? I have stuff to do during the day, I can't be continually inebriated.

135 Halloween

Have you tried shopping online? It can take less time.
Yea but then I get distracted by the interwebs and can't study.

You don't want to hear about my exciting plans to make flashcards then, huh?

iPhone app!

Hey everyone!
An awesome new development has happened in the last week or so. The iPhone/iPad/iPod app "Web Comic du Jour" has graciously added Indeterminate Causality to their list of supported comics!

This app is AWESOME. It has (at the time of this post) over 400 comics available for daily browsing, and puts them all in one place! I use it almost every day to keep up with the comics I like to read, and I highly recommend it.

The free version can be found here but if you're feeling generous, please consider the ad-free version (as of this post it's only $1.99 which is a bargain in my mind).

I hope you're enjoying my work!

He's under A LOT of stress. But at least he's working on it.

If any of you are still under the ridiculous impression that girls don't poop, this is medical school, wake up.

130 Know This

No, I'm not saying that you shouldn't study anything else from this lecture, I'm saying that this slide is important.

129 Resistance

In this case the phrase "Resistance is futile" is actually completely inappropriate. "Resistance is lethal" would be more fitting.

I won't tell you stories about that. Not because I can't remember, but because I don't want to digress from the lecture too much.

That should be a law. Plus, it would make treatment less complicated and probably allow for better patient care/outcomes.

You know, you confuse the crap out of me sometimes. Why can't you just use normal expressions?

125 Goiter

You may not want to yell that at her, that would be pretty rude. But that's basically what it means, if you were confused.

Obviously the author needs to get out more.

I mean, if you guys did it, it probably wouldn't come out nearly as good as the automated version, let alone the quality of a trained lab tech.

OK, sorry about that. I might have gone a little overboard there. Damn, that was a nice podium. Oh well.

Sure kid. And remember, if you eat your fruits and vegetables you can grow up to be big and strong like me, and one day, just maybe you can take prodrugs too.

121 Diabetes

No, I'm not saying the horse has diabetes, that would be ridiculous to assume. It's just a euphemism, relax.

I did that once during a presentation and had a whole group of pathologists in uproarious laughter, which is a feat in and of itself.

I mean, if there was ever a reason to do well on your boards, it's definitely so that you get to wear comfy scrubs.

Yea, by the end of the lecture I'll probably have to go, I had the beef and bean burrito from the cafeteria for lunch today.

108 Endocervical

Dude that movie was horrible, and a while ago.
I know, but for some reason I don't think I'll ever forget that character, and now I won't forget Nabothian cysts either.

Yes, I would perform a transabdominal pre-peritoneal (TAPP) repair on her as well, and I'd be sure to use my laparoscope.
