This article estimates at a 40kg sailfish uses about 2.7 megajoules per day of energy when hunting. That’s about 650 kcal.
An 80kg human weighs about twice as much and needs about 3 times the energy, without even exertion.
Warm blooded animals spend a lot of energy just maintaining body temperature. Plus water doesn’t have very much oxygen in it, compared to the atmosphere.
There’s not enough oxygen in water to support our metabolisms, even if we had gills.
Fish are adapted to conserve and use less oxygen, from slower metabolic rates to more options for anaerobic respiration that doesn’t poison oneself from within.
Any idiot can build a bridge that stands. It takes an engineer to design a bridge that barely stands.
I agree. Stated another way, imagine the trolley is headed towards 5 people, and you have the power to pull the lever to divert it to a path where there are no people. Even if someone tied those 5 to the tracks with the intent to kill, your failure to save their lives (at no additional cost to others) is widely regarded by most systems of ethics/morality as a moral failing. Yes, the person who tied the tracks bears blame, but so does the person who could’ve easily saved them but chose to let them die.
I love the way you weave in the cultural context, including the culture war parts of modern political and policy debates, the business/corporate trends in entertainment, in your telling of this history. It’s clear you know your stuff, and you’ve helped me understand something new (the influences these slasher films drew from, from Agatha Christie), grounded in stuff I might have already known (the actual movies themselves and the cultural context they were released into, including how people looked at boobs before the internet).
So thank you. This comment is awesome, and you make this place better.
$83 billion per month is almost $1 trillion per year. That sounds about right.
No, no, the bigots hate people who speak French too
I don’t see why the distance between them isn’t growing at a constant speed.
At any given time t seconds after separation, the boy is 5t north, and the girl is 1t east. The distance between them is defined by the square root of ((5t)^2 + (t)^2 ), or about 5.099t.
In other words, the distance between them is simply a function defined as 5.099t, whose first derivative with respect to time is just 5.099.
No such thing as an NDA that allows a spouse to work in the same room, and allows the spouse to actually be on video while blurred, but draws the line at not being able to unblur the video.
All women should be cleaning regularly. Power clean, hang clean, full clean, doesn’t matter.
I’m not into that. Can I still be a carnist if I worship a flesh daddy instead?
Shouldn’t the DE/Window Manager be handling that? Seems like doing it on a window by window basis would be inefficient (and look inconsistent).
Your dentist’s name is Crentist?
I think my personal resource consumption, if scaled up to the world population, would be devastating. That’s what I mean by categorizing myself in the “rich.” I might not be a billionaire, but I’m far, far above the global average, and still significantly above the national average for my nation.
Yeah, having kids probably reduced my household resource consumption, compared to the dual income no kid lifestyle that my wife and I had before kids.
Population growth is so far disconnected from resource consumption, because people’s resource consumption does not resemble a bell curve. A private jet produces more CO2 in an hour (about 2 tonnes) than the average Indian produces in a year (about 1.9 tonnes).
The poor people having children aren’t destroying the planet. Rich people, childless or not, are. (And yes, I acknowledge that I fall under the “rich” category here.)
If you follow the Arch installation guide it’ll get you to a working system, but you’ll need to install sudo yourself. It’s not strictly required so it’s not installed with the essential packages (or even the packages recommended for most users in the guide).
Yeah, timestamps should always be stored in UTC, but actual planning of anything needs to be conscious of local time zones, including daylight savings. Coming up with a description of when a place is open in local time might be simple when described in local time but clunkier in UTC when accounting for daylight savings, local holidays, etc.
Self deprecation comes off wrong when it seems like the thing you’re criticizing is actually important, and that you actually believe it.
So it’s funny when the audience knows you don’t believe it’s important, either because everyone agrees it’s not important (“I can’t sing on tune to save my life”) or if it’s a particular example that doesn’t matter (“I’m such a bad mom because [something inconsequential]),” or if it’s a topic that people can see isn’t important to you (jokes about being socially awkward, bad at your job, etc.).
If you’re in one of those lanes, you can go pretty hard on yourself before it seems to go too far.
Yeah, evolving lungs ended up clearing the way to make use of the much more plentiful oxygen in the air compared to what is dissolved in water. Amphibians and reptiles have pretty low metabolisms, but birds and mammals basically evolved endothermy (aka warm bloodedness), probably in support of much higher muscular power output. Ectotherms (aka cold blooded animals) have metabolisms that are correlated to temperature, which means they can’t exert themselves as well when it’s cold. Endothermy allowed animals to be warm all the time, and therefore use higher muscular power output in any environment, especially sustained.
That means mammals and birds were able to cover more distance, and survive in places where reptiles and amphibians can’t, and all the advantages that carries.
