I'll be very grateful if anyone here wants to recommend something like I described

I'm the OP of the above linked question, I've just found out it's off-topic, sorry I didn't check the guidelines.

@Chieron Oh, I misunderstood your comment. Sure, it would require to make more than two signs, but after all today we may express 20 showing our open palms "twice". At least, in Italy it can happen.
Nov 20, 2018 11:02
@Chieron: Combining left and right hand (the former counts units and tens) one can (albeit, not easily) represent any number up to 10000.

@Secret Nice!
Aug 8, 2017 11:58
Damn, it's a pity, I'm sorry to hear that
Aug 8, 2017 11:53
@TobiasKildetoft Precisely. Cheers
Aug 8, 2017 11:51
Indeed. I think one ought to stress that. In a way, this seems to me another argument to undermine the "equivalence"
Aug 8, 2017 11:47
@TobiasKildetoft Yes, my professor did illustrate it in that context. However, in the chapter on orderings, this equivalence is shown. Freiwald goes so far as to say "it is the well-ordering property that lets us do mathematical induction in $\Bbb N$". Do you think it is a plain mistake to put it like that?
Aug 8, 2017 11:35
I see
Aug 8, 2017 11:33
In $\Bbb N$, it coincides with PMI
Aug 8, 2017 11:32
If a set is well ordered, then transfinite induction is valid in it
Aug 8, 2017 11:30
@TobiasKildetoft That's precisely what bothers me. It's somewhat vacuous that the WOP implies the PMI because the latter has to be true in the naturals, and whenever you get in another set, the implication is no longer true and you have to settle for transfinite induction
Aug 8, 2017 11:24
What's the point in saying the Well Ordering Principle is equivalent to the Principle of Mathematical Induction, when the latter is a direct consequence of how $\Bbb N$ is defined, i.e. as the intersection of all the inductive sets? I mean, if the PMI is a priori true, isn't it inevitable that the WOP implies it?

Yes, writing on the board also makes sense. You would even prefer writing on a sheet, I guess

Q: Are there advantages to make students handwrite (instead of LaTeX typing) what they say in an oral exam?

Vincenzo OlivaIn my university, in Italy, most professors want the students (at least the undergraduate ones) to handwrite what they are saying in an oral exam. If I understood correctly, this is somewhat due to needing an official document for the oral exam. Does this occur in other countries too? It's not u...

Jul 20, 2017 18:22
Can't paste it
Jul 20, 2017 18:22
@Semiclassical If you had to write during the oral exams, would you have preferred to handwrite or LaTeX-type (assuming you would have had a LaTeX course in the first semester of the first undergraduate year)? Here is my original question, if you didn't see it:
Jul 20, 2017 18:08
@Semiclassical I see.
Jul 20, 2017 17:59
@Semiclassical Was it Mathematics or was it a mathematical science / Engineering?
Jul 20, 2017 17:55
@Semiclassical Do/did professors make you write (most of) what you said in oral exams?
Jul 20, 2017 17:51
@Akiva Yes, it's a class of math, but what if LaTeX-typing is better than writing, during an oral exam?

Fair enough, thanks.

@C.E. Would this bug extend to Mathematica, or finding the same result would actually mean WA was right?
May 28, 2018 20:16
Can Wolfram Alpha get a limit wrong?
 
Aug 18, 2017 19:21
I see, thanks to you! :D
Aug 18, 2017 18:52
Thanks. I've updated my answer

Indeed, it seems Western Union is not involved! How many "respectable" articles debunked
Aug 18, 2017 17:03
then I'll further edit my answer, I'd be glad if you could give me feedback here on the edits
Aug 18, 2017 17:00
Yeah, I guess ahah
Aug 18, 2017 16:46
Of course what I think doesn't matter, that was just a comment; this is a chat, isn't it? :D

I'll have to read Rockman's work. But I would agree with his work only if he proved that Meucci's materials were actually lost by Western Company
Aug 18, 2017 16:40
As for Rockman
Aug 18, 2017 16:40
(I meant " telettrofono " and similarly for the "English" word ) If anything, I think that description is simply wrong. Why would Meucci even found a company, prior to the whole controversy, whose name indicates the electrical nature of the device?
Aug 18, 2017 16:33
That's utter nonsense, the device was called elettrofono, "electrophone". Meucci started to think of his design after some electrotherapy experiments in 1849. And Giovanni Schiavo is an Italian-American historian who defined the verdict you mentioned as one of the most blatant judiciary mistakes in the annals of American justice.
Aug 18, 2017 16:33
Thanks, I'll edit my answer a bit. Anyway, do you doubt Bell exploited Meucci's materials?
Aug 18, 2017 16:33
It is true that HR269 doesn't explicitly credit Meucci with the invention of the telephone, but the sentence "Whereas if Meucci had been able to pay the $10 fee to maintain the caveat after 1874, no patent could have been issued to Bell" is very telling. Otherwise, The Guardian would have refrained from being explicit in the article I linked to.

@T.E.D. The only relation is that the food is named after the Italian film "Stromboli" unfortunately. But I'm sure you would love (because everyone does) the real local food, try to visit Stromboli & co. sooner or later!
Aug 11, 2017 15:28
Generally, that's the thing. However, if I recall correctly, these ones had also a mythological value or something. If I ever get to know more about it, I'll let you know here.
Aug 11, 2017 15:24
@T.E.D. Indeed, thanks for your help!
Aug 11, 2017 14:56
@T.E.D. (Yes, the islands are Sicilian) I see... but if that's the case, I guess those stolen pieces were subsequently lost, otherwise today they would have to be returned to Italy, right?
Aug 10, 2017 15:03
*pieces of them
Aug 10, 2017 14:46
During a trip to the Aeolian Islands (I can't remember which one exactly), a guide told me that some of the antropomorphic cliffs were stolen (well, the important pieces of it) by Napoleon to be put into French villas. However, I can't find anything backing this up, and I actually learned that British troops protected the Islands. Does somebody know something about this?
