How do we know that the two statements
>There is no largest natural number

are equivalent? Never mind whether this implies that the set is infinite or not, how can we prove that it isn't just a finite poset?

Even if x is the largest natural number, then x+1 still exists, it just isn't a natural number.

>> No.11210095

The natural way of putting your two > into formal terms would be the same, namely that for all natural numbers, there's a new bigger natural number. The prove is to map x to x+1.
The assumption in that is that N is well ordered, which is the case due to their axiomatization. This holds for all the models.

The set given by "N without 10" just isn't the set N we talk about here in the two > statements

>The set given by "N without 10" just isn't the set N we talk about here in the two > statements
Sure, but when you fix that set then the two statements are trivially equivalent because they're both true, right? That would make the question uninteresting.

Like I said, depends on where you go. Rent fees in San Francisco are some of the highest in the world, but most places outside of the biggest cities are pretty affordable.

MSc is coursework based with a research project like an undergrad dissertation but bigger.

MRes (MScR, etc.) are largely research based - typically in preparation for a PhD, and are normally part of Doctoral Training Programmes where 4/5 years are spent studying/researching with the MRes for the first year (and maybe second) and the PhD for the following 3.

If you want to do a PhD, consider applying for a Doctoral Programme where you get a MRes followed by a PhD, or simply just apply for MRes and do PhD elsewhere, etc. You could do MSc if you are not as confident in understanding of your field before going into research (maybe?), or you could do a MSc before going into industry.

>> No.11210323

so a MSc would leave me more options in case i changed my mind about research, mmh.
MRes will give me more practical experiences over pure theory, so many lab hours, right?

Standardized testing in its current form does very little to test skills other than point out who the bottom of the barrel is. It does well at measuring the reading/mat/etc abilities of an entire population of students who, on average, would normally fail a final semester exam on the topics. We need testing to gauge the abilities of students but we also need more difficult yet accurate testing.

I wanted to know how you guys feel about grading according to a certain curve.

Does it systematically put your letter grade higher or lower than it should be if grading was absolute?
Do you feel compelled to study more if the course is adjusted to a curve or not?
Do you feel like you shouldn't help your peers to learn since that would hinder your chances to get a higher grade?

I'm confused: how a monitor can damage your eyesight compared to paper?
Does reading a physical book is worse because of poorer contrast and slouched posture?

Even if humans did have precognition, they would have it in a way that would make them unaware that they have it. If somebody was aware that they were seeing the future, they would eventually draw the conclusion that anything they see is unavoidable. But thinking like this renders the ability useless, because just possessing the potential to go against what you see, alters what ends up being seen.

This is because of the Novikov Self-Consistency Principle. When you make an observation of the future, the future becomes one of many possible states, but those possibilities are influenced by the act of you making an observation. If you see a future that you'll want to avoid, then reality will have to resort to contrivances in order to make it happen even after you observe this. In this way, the universe will take a path of lower resistance, and tend toward futures that you aren't going to actively attempt to thwart, except when providing a desirable future requires more contrivances than an undesirable future.

So in order for something to use precognition, it has to always think it can go against what it sees, even if that never happens based on past experiences.

You can hone this with training, become an empath, I myself am an empath with 20 years of training. The materialist plebs here will balk or w/e but they are NPC shudra fascinated by the illusion.

If you want to understand this ability watch a tv show called The Mentalist. Being this ability is like studying any other field of knowledge. Essentially what you are doing is learning the mechanics of the matrix (including the humans) and it makes you able to predict outcomes more accurately with less variables than normies, your gut feeling/institution.

You may be able to easily predict the outcome of some experiment you set up than some podunk from /pol/ who doesn't even understand the variables let alone how to predict how they will interact and the outcome they will produce. Well just s you tower over them in this regard empaths tower over in what they can predict in this reality because they see and understand variables muggles don't. Think of Sherlock Holmes and his "supernatural" abilities to the outside observer. However to him they simply normal and logical/reasonable he simply sees things you don't and his mind knows how to crunch those variables to determine probable outcomes and his mind does it intuitively, he doesn't have to work through it, the mind simple crunches them unconsciously, just like a great athlete that can make an amazing play without thinking about the physics ie angle and sped of the ball, x vert factor to jump at y coordinate etc, they just know when to jump and when to where the length of their arm will be in the correct spot to make a once in a lifetime catch that will be on sports center highlights
