@JasperLoy yes it might have been expensive nowadays. And going by the review, the low cost decent ones are really crap. But back then when my dad bought it for me it was good :-) by the way I now am sceptical about Lenovo due to other reason. I bought two flagship Motorola phones. I had full trust on Moto devices, and I was satisfied with the performance and update frequency and their software.
But unfortunately few days later Moto was acquired by Lenovo and since then stories changed. No promised update and lots of software bug, and due to which phone started to accumulate heat etc. So I now am a bit "no-no" about Lenovo. Though it doesn't mean that just because their one product is not meeting expectation, their other products are bad. But as I said the reviews of low cost on paper decent laptops are not good as well. I have not looked into their expensive laptops
Because I can't afford them. And if I save money to buy such expensive laptop, I will go for other brand like HP.

> An infinite number of mathematicians walks into the bar. The first says to the bartender: "pour me 1/2 of a liter of beer". The second says: "Pour me 1/4 of a liter". The third says: "pour me 1/8 of a liter". The bartender looks grimly and says: "don't make me mad, here's 1 liter for all of you".

Word of the day: halmos

Tombstone (typography)
The tombstone, Halmos, end of proof, or Q.E.D. mark "∎" is used in mathematics to denote the end of a proof, in place of the traditional abbreviation "Q.E.D." for the Latin phrase "quod erat demonstrandum", "which was to be shown". In magazines, it is one of the various symbols used to indicate the end of an article. In Unicode, it is represented as character U+220E ∎ END OF PROOF (HTML ∎). Its graphic form varies. It may be a hollow or filled rectangle or square. In AMS-LaTeX, the symbol is automatically appended at the end of a proof environment \begin{proof} ... \end{proof}. It can also...

@CowperKettle Paul Halmos wrote some very nice books, like Naive Set Theory and Finite Dimensional Vector Spaces. He is very good at using words instead of excessive symbols to describe mathematics.

@JasperLoy Oh!
You know math? I never heard of him, and never heard of this theory.
Knowing math is cool.

@CowperKettle It's just a gentler introduction to set theory.

@userr2684291 That book is actually a naive approach to axiomatic set theory instead of what the title says.

@JasperLoy I don't think anyone would willingly write about an inconsistent theory, if that's what you're implying might be the case.
@DManokhin Hello.
I read the book a couple years ago. It was a fine read because it didn't pour a lot of information into your head; rather, the author was apt to do it gradually, one axiom per chapter, or something like that.

But I've always found math hard to digest.
Because when you're studying math you need some time to really digest it. And that means understanding the reason behind every single symbol in a proof or axiom. And of course, you don't want to reveal the proof until you've tried to do it yourself. All that takes a lot of time.
I'd felt that not doing all that was... cheating.

@userr2684291 I mean it just treats the axioms but does so without logical formalism, which is mentioned in the book's preface itself.
