Last year, in total, British police officers actually fired their weapons three times. The number of people fatally shot was zero. In 2012 the figure was just one. Even after adjusting for the smaller size of Britain’s population, British citizens are around 100 times less likely to be shot by a police officer than Americans. Between 2010 and 2014 the police force of one small American city, Albuquerque in New Mexico, shot and killed 23 civilians; seven times more than the number of Brits killed by all of England and Wales’s 43 forces during the same period.
Edgar Wright - How to Do Visual Comedy
As a die-hard Edgar Wright fan, this was pure love for me.
Ask for more from your comedy.
Worth thinking about w comics too, esp. the bits about transitions. (The train, the pub taps, etc.)
Science Needs Women:
For Women in Science; the L’Oreal Foundation
I’m sharing this video on any platform I can because when I first found it last week it had something like 1,400 views, but it’s the most beautifully produced and succinctly narrated video addressing some of the most complicated issues facing women in STE(A)M fields I’ve found yet.
I’m sharing this for every time I’m called a “feminazi.”
…for every time I’m told that my concerns aren’t valid, our that our issues are imagined.
…for every time I hear “women just don’t like science,” or worse - “women just aren’t good at science.”
…for every time we’re told that we can have a family or a career, but not both - and for every time we feel like we have to decide between the two.
…and because we need more women mentors in these fields to stand up for issues that are not “women’s issues” - these are people issues that affect our collective society as a whole.
The women in this video are my heroes and they should be your heroes, too.
Science needs women.
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…?
