passive aggressive family members
"guess i’ll never be a grandma"
"guess i’ll never be an aunt"
"guess i’ll never be able to dress a niece/nephew"
stop feeling so entitled to my hypothetical offspring. it is not yours. it is mine. i will grow it if i grow it. and it will be mine. not yours. i am not an incubator which grants you familial titles. jesus. go away. this “have a baby i can play with” thing is so impersonal and insensitive and annoying.

Victoria’s show is designed to be sort of a video lab notebook, part educational, part experimental. YouTube already has some pretty great science shows (*cough*cough*) but I’m happy to welcome Victoria to the fold. And Iggy too, I guess.
In this episode, in addition to meeting the main characters and hearing some inspiring words about the importance of failure in the scientific method, we learn a bit about cardiac electrophysiology, those nerve impulses that control our heartbeat.
I find that GIF hypnotic. The human heart has its own pacemakers built in. One is known as the sinoatrial (SA) node, the other as the atrioventricular node (AV). These are the upper and lower red dots above, respectively.
Cardiac cells are interesting because they are sort of like nerves and muscle cells combined, they can do work, but they can also propagate electrical impulses (although we should be clear, they are definitely classified as muscle cells).
Cells of the SA node sort of “leak” charge at a constant rate, which makes them fire (or send an electrical impulse) at that same constant rate. The result is a nice rhythmic heartbeat, controlled by its own cells.
When a heartbeat is initiated by a stray impulse at the bottom (ventricular) region of the heart, that’s what is known as a premature ventricular contraction, or PVC. That’s what happens to Iggy in this episode.
Single, isolated PVCs are pretty harmless, and most of us probably get them from time to time without even noticing. Leave it to Iggy to kill himself by trying to fix a problem that doesn’t exist.
At least Victoria was there to shock him back to life! Wonder if she’ll do that again at some point…?
Looking forward to doing a “Science of Frankenstein MD” episode of SciShow. Thanks to Joe for doing all the science consulting on the show. I LOVE how it’s turned out…such a cool mix of comedy and plot and information and quirkiness. So cool! The first three episodes are already live!!
so i bought this ring that has a little hinge and it opens up to a tiny secret box hidden under the gem and my mom told me that women used to put poison in it and then SLIP POISON INTO PEOPLES DRINKS and i was like NUH UH THIS CANT BE REAL and i just googled it and guys this is like a real thing
people are psycho
I have a few of those. I think they’re really neat!
This is Sniper’s right thumb I’ve seen in various sfm photos. Did he hurt his thumb or something? His thumbnail is all black but the rest of his fingers/nails are fine looking.
His sniper rifle has a manually operated bolt action on the right-hand side. The bruise (a subungual haematoma) is caused by trying to reload too fast (too many people wanting him dead on the battlefield?) and getting his thumb caught in the sliding mechanism.

Watch how his right hand moves to pull back the handle, unload the spent cartridge case, and slide the fresh round into the breech:

The bolt-action mechanism looks something like this (source: wikipedia) - it is allegedly quite painful to get your fingers pinched in it:
That’s Valve for you - completely ridiculous canon, perfectly detailed character designs.
