So about 3150 pints of blood (10.5 being average for an adult).
Sounds doable XD

I have a rare medical condition that makes my coughs sound like “scihub” and “libgen” around undergrads.
I would like to investigate it further to seek a cure, but sadly the medical journals I’d need access to are paywalled. Oh well.
- Comment on Zero to hero 1 week ago:
I’m arguing from the standpoint that we establish the idea of counting using the naturals - it’s countable if it maps to the naturals, thus the link. Apologies for the lack of clarity.
- Comment on Zero to hero 1 week ago:
On the contrary - to be countabley infinite is generally assumed to mean there exists a 1-1 correspondence with N. Though, I freely admit that another set could be used if you assumed it more primitive.
- Comment on Zero to hero 1 week ago:
N is the set of “counting numbers”.
When you count upwards you start from 1, and go up. However, when you count down you usually end on 0. Surely this means 0 satisfies the definition.
The natural numbers are derived, according to Brouwer, from our intuition of time of time by the way. From this notion, 0 is no strange idea since it marks the moment our intuition first begins ^_^

- Comment on If you take care of your parents or other elderly, how are you preparing to age gracefully? 2 weeks ago:
My options are likely to be:
A) Live 5 years unable to remember my work, with added incontinence.
B) Go out trying an experimental age reversal treatment - because why not roll the dice one last time?
C) Not survive to old age due to overwork, burning out my body one semester at a time.
C is most likely, B is the plan, and A is to be avoided at all costs!

[X] Member of the EU. [X] One of the wealthiest nations on earth. [X] The best healthcare on earth. [X] One of the strongest higher education sectors on earth.
All sounds good to me.
The first was lost to the old voting for the young. The second fled with austerity - slowly eroding the wealth of a nation. The third succumbed to a slow cancer of underfunding and an unfolding demographic crisis. The fourth is about to fall due to nationalisation and massive underfunding.

Yup, he definitely belongs in a stable.

“Because I was bought up to be a moral person who put the wellbeing of others before myself - why would I inflict a world that defines a person by their job on anyone?”

So, let’s say you write down the words “fire is a chain reaction between carbon and oxygen that produces heat”. You’ve characterised fire yes, but is that sentence itself the fire?
Let’s say you write down the equation describing this reaction so you can play with it and manipulate it. Is this fire, or just a convenient way to talk about it?
I’d argue neither of these are fire, and both will never completely describe a fire (though they come damn close).
- Comment on STEM 2 months ago:
You know, I’d never considered that, but yes that does indeed seem to be the case!
- Comment on STEM 2 months ago:
See now, I’d argue that the language comes after the mathematics. For example, I walk to work each day; part of walking to work is trying to find the route that lets me lie in the longest.
Now, humans are pretty good at exploring and finding alternative routes between locations, and they also tend to locate the shortest route given enough time.
Trying to explain how this intuitive activity works necessitates the use of graph theory. The graph theory was something our brain had constructed in the background, but it wasn’t entirely conscious. Trying to explain this in natural language would take pages, however…
Given a set V of street intersections, and a set E of streets connecting two intersections, and a set W of weights assigned to each E. I can calculate the shortest route by applying one of the pathfinding algorithms (which are expressed in this notation).
This explanation will cover any pathfinding problem, but it’s not great at conveying what is a really happening. The language we must use gets in the way of conveying the mathematics that is going on.
We do need a language (telepathy not being on the menu), but that language is a separate entity from the mathematics itself.
There are “mathematical languages”, but these are present to describe mathematics. There are mathematical theories of language, but again the language itself is not mathematics - its structure, however, has mathematical properties.
I suppose you could say “fire has the property of being hot, but it isn’t hotness itself”? Language is used to communicate mathematics, but it is not mathematics itself.
Now, this is not to discount notational developments in easing communication - that’s a great branch as you have to check your new language and its rules match the mathematics it tries to describe. However, again, it’s important not to conflate the thing you are describing with the thing you are using to describe it!
- Comment on STEM 2 months ago:
Pure mathematician here - some of us argue “mathematics is a language”, others of us argue “language gets in the way of mathematics”.
The latter feels much more true; as a species we’re absolutely awful when it comes to talking about abstract things. The thing is, those abstract things are often VERY interesting.
It’s like making a map and being fascinated with the type of trees rather than the shape of the land, because the types of trees tell us about the climate, soil, and even history of the land.
- Comment on Has google stopped working for finding anything? 4 months ago:
It gives normal distribution questions, but not actual use cases (I was looking for a normal model based on actual data rather than just made up values).
You’re looking for normal distributions in chemistry, biology and real estate.
- Comment on Has google stopped working for finding anything? 4 months ago:
On the contrary, that is their function, one they used to be good at.
- Comment on Has google stopped working for finding anything? 4 months ago:
I can give a fun example for both ddg and Google:
Earlier today I was writing an exam paper for my students, and one of the topics is “basic” normal distribution. So, I thought to myself, why not make it I testing, give them a real world normal model.
Try it yourselves - the number of bot reposts is frightening.
