advice on learning the formulas not demonstrated

[funghet]

Good evening, everyone. I really need some advice. there are some exams where they require to learn an amount of empirical formulas by memory. but is it possible to really have to take an examination with hundreds of formulas to learn from memory? in the upper ones gave us the manual of mechanics to recover all the formulas to use for the verifications... at university apparently no forms are allowed. . but really the preparation of a student you see from the amount of formuline studied by memory that in a few months I have already forgotten most? in high school we have always been told that the important thing is to know the concepts and how to reason to get to the solution, if the theory did not study it, the formulas will not serve you to nothing. University seems to have been made 100 steps back... I understand if they were formulas derived from theorems demonstrated in lesson, but unproven formulas makes no sense to have them learn by memory... for charity some learn them but you can never remember them all to perfection. you risk compromising a preparation of weeks and months for having confused a value of a constant with another...
Would someone really know a tip to remember a high amount of formulas? Doing a lot of exercises apparently is not enough...
Thanks for the attention, good evening.

There is a method, called the "memory palace" that allows you to store "easy" a great deal of information. However, it is not a method you learn from today to tomorrow. They use all the mnemonists.

I agree with you, can I ask you for which exam, without specifying one? In my case I remember that at the examination of mechanical technology there was given a single sheet from the prof that contained the main formulas, since impossible and especially useless to learn by memory. the important as you say was really understanding the problem and then knowing which formula to use from the catalog. discourse changes regarding formulas or equations "fundamental", which usually express physical laws.
a mechanical engineer who does not know that f=ma or m=iw is quite serious

I come back to my mind that day when my daughter came home with a table, in split the main corners and in order the trigonometric functions, telling me that she had to learn all by heart.
It is inconceivable as a teacher prefers to make one thing like this learn by heart rather than to reason on every single function, to calculate the exact value for every possible angle.

well come to the university system with its contradictions.
then you wonder why you copy... .

Good morning.
Could you specify in which university studies?

a good day.

Gentlemen. how do you need to learn formulas by heart? and poems by heart? and what do you need to learn how to make calculations in mind? simple: it is used to train the brain, to make sure that you do not atrophy, that you do not hang.
I would like to make a sporting example. We put that one enters into the football team and the coach puts it in the gym and does weights horrors a week instead of on the football field kicking the ball. I'm a guy who might think; What do you need to do all the exercises in the gym, if I only have to kick a ball? Maybe it can serve to train, strengthen the body, to prevent infotuni, to run faster and longer, to jump higher, to better resist the contrasts of play. here ultimately serves to play better football.
so to exercise and mind can be useful to learn notions by memory, both for having them always at hand, and to train the mind. ceverllo is an organ that must be trained.
this concept that the school should not demand from students who learn something by heart, it is an unpacked box, which goes very fashionable now. The school should teach you to reason. Right, sure, but if you don't know the notions, what are you thinking?

I am in total disagreement with what you support.
math, as well as physics and other subjects, are not given by nature, but created by man, to give a measure to all that surrounds us.
Mathematics, in particular, is a chain where each ring is the development of all precedents, formed solely by reasoning that led to formulas, principles, theorems etc.
remember by heart a formula, without knowing how it was created and where it comes from, does not even allow you to know how to apply it at the right time.
the notions, especially if fundamental, are part of reasoning, cannot be excluded a priori, otherwise it is not going anywhere.
but I see that my example posted #4 is not served at all, then blessed are those who have an iron memory.

Good evening to all,
I fully agree with you rotten, reasoning and intuition are far more cheerful peculiarities than memory.

Good evening,
I graduated in mechanical engineering (magistral) almost 5 years ago and I remember very well the blasphemies that I had to draw to remind me of the much hated demonstrations rather than formulas or diagrams. having had the opportunity to make 6 months in erasmus in france and after working for more than four years I made a clear idea about the approach of Italian engineering faculties. the point is that Italian engineering faculties may not prepare for the world of work like those of other European states but are much more selective. who manages to end up in times more or less consons very likely will work well. Unfortunately, I have quite a divisive opinion on memory speech. I have never met a smart student with poor memory and not even a little smart with much memory. being able to remind you of a series of information at least until the second after you finish the exam is one of the things that I think distinguishes a good student from a less good one. seeing careers that have done my college colleagues I have to say that in general those who went better at university have had better careers than those who went worse. ergo according to me select the students also, but not only, for their mnemonic abilities has its logic. for charity then exceptions exist but are exceptions (I was good but in 5 years I did not grow from any point of view). in any case memory is something fundamental even in the world of work. probably at work will not be necessary to remember the demonstrations but generally carry out many activities at the same time and you must always stay on the piece never forgetting anything on the street. So I believe that memory is also fundamental to the world of work.

I can tell you that it is actually true. the Italian university selects strongly even if it does not really prepare for the job. But... fans understand that outside is a pond with sharks.
averagely it is normal to have to remember main formulas even if it is better to know how to get them and then to the need....you always get to solution.

having well fixed in memory some fundamental notions is certainly useful but I do not know whether it is indispensable. about working memory, I remember very well that during one of my very first working days, an elderly colleague recommended never to go to memory when it comes to work. a few years later, a wise owner of another company in which I was working, about going to memory on work, made me the example of the musicians of the symphonic orchestras. . each of the older musicians will have played at least 500 times each of the songs played in their career, but you will always see each of them turn the score page when necessary. therefore it is always necessary to consult the documentation available and not to rely on the memory. on learning from memory in school, I read on the net that there are discordant opinions; It seems useful at the beginning of the learning path while it would be less useful during higher education.
