Could you translate any and all forms of math to english, spanish, german, whatever needed

Dear all, to become a teacher I have to deduct a research to improve my teaching and/or to "solve" a didactical problem I encounter. This research, my proposal for a solution etc. has to be motivated by scientific literature. I observed that a lot of students have problems with formulating...

Is there yet a programming language for implementing processes that use probabilistic bits (p-bits)?

The following quote caught my eye. I presume that buffer overflow, heap management, and pointer validation are the shortcomings of C that lead to insecurity. But the broader implications make me curious. What other features of a programming language directly aid security of the products...

Quick question, when discussing induce emf, would you state: "An emf is induced in the coil..." or "An emf is induced across the coil..." The reason I ask is that grammatically, it sounds proper to state "An electromotive force is induced in..." (something). However, an emf is a potential...

Hello, When I attend art course in high school, on (Western) Music Theory subject, there are a lot of terms in Italian, especially on tempo (largo, adagio, moderato, allegro), dynamics (piano, pianissimo, forte, fortissimo, crescendo, decrescendo), and curves (legato, portato, staccato). Is it...

I recently encountered the Scratch programming language. I wonder what people think of it considering some notable (IMHO) shortfalls. I do not like the way it handles comments, the lack of returned values from "functions", and some other aspects that I think should be basic. But it does seem to...

There are so many bizarre traits of the English language, but for me the concept of Homographs, Homophones and Homonyms take the cake for me. It must drive English as a second language leaners bonkers! Homographs are words that are spelled alike, but have different meanings and sometimes...

I’ve heard that C++, python, and IDL are most commonly used in observational astronomy research, but how common is R in the field?

It looks like Javascript is the way things are heading. But I've also seen C++ and Python recommended. I don't want to waste time and energy; I've done enough of that. Any job I get will probably be based on my having a 4 year degree (STEM preferred and no gpa requirement) and programming...

I found this article interesting: https://www.cell.com/current-biology/fulltext/S0960-9822(18)31672-5?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0960982218316725%3Fshowall%3Dtrue They played audio of word pairs during slow wave sleep and detected the learning of this...

Homework Statement I am self studying automata theory and I found a problem set from an old class I took a few years ago, but I have no clue how to solve the following problem, any help would be appreciated.Suppose we have a regular language ##L \subseteq \{0,1\}^*## and the language ##...

I'm trying to figure out how to use the search interface on publicnoticeads.com. In the "advanced" search screen the field "With at least one of these words" does not work correctly. It appears to require all the words you list. For example if I set state to be NM, the county to be Dona Ana...

This is in reference to post #10 and 11 in https://www.physicsforums.com/threads/i-dont-have-physics-what-can-i-do.958089/#post-6075184 These are NOT what I am listening to now, as like another of the forum topic. This is just to show an indication how widespread is this both used and...

Homework Statement "Let L be any regular language over an alphabet Σ. Using L, we define chop(L) = {w : ∃ x, y, z ∈ Σ∗ , xyz ∈ L, w = xz}. Show that chop(L) is regular or give a counter-example." Homework Equations If an NFA that describes the language chop(L) exists, then chop(L) is a...

A few years ago I read two pretty groundbreaking linguistic papers from the 90s arguing that natural languages are networks which can be conceptualized from the perspective of nonlinear dynamical systems theory, with a lexicon being a state space and grammatical rules being attractors in that...

What are the best software solutions for language translations? Is Google Translate the most advanced one? I heard about Babylon. Is there anyone who uses it? Can they share their experience with Babylon? In the past I tried some but the sentences translated by them was wrong. I will give feed...

You guys still use assembly when programming these days?

Hello All, OK, I have been programming since the early 1980's. Programmed in many different languages along the way such as Pascal, C++, C, Visual Basic, and some C# (among others). I pretty much program so that I can model physics. I find it GREAT way to actually understand the physics...

Some people claim that they have two mother languages. This seems to me very strange. Is it reasonable or scientific to have more than one mother language? As far as I know, mother languages and foreign/learnt languages belong to different parts of brain. One of them was a immigrant family...

Hi everyone Apologies if this is the wrong place to ask, but I was wondering how much data there was in a language (let's say English). So for example, if you were to program a computer to speak English fluently, how much data would all the vocabulary and rules of syntax take up?Thanks

This is a phrase I hear from time to time from people who obviously don't know what it means. These people mistakenly believe it means "man to man" as in a confrontation between two men. The direct translation is "hand to hand," and describes close-quarters combat using swords or the like. The...

QUESTION: I read in book that in beta + decay proton decays to neutron But i can't understand how it is possible if proton mass is less than neutron mass.I read on net but it says 'quarks' and 'd u p' things which i don't study about currently. Also why it only happen inside nucleus?What...

Homework Statement Occasional, MTW's use of language is a bit obscure. I've highlighted a section from p491 (attached) which I just can't make any sense of. I know about the 20 components of Rαβγδ but what does "these twenty components are arbitrary to the extent of the six parameters of a...

Homework Statement Let CRYPT be the language of cryptographic expressions of this type that can be generated by the following grammar. S → E S → ε E → E + E E → E − E E → SIMPLESUB(E, STRING) E → VIGENERE(E, STRING) E → LOCTRAN(E, DIGITS) E → STRING In this grammar, the non-terminals...

I am wondering what programming language, whether it is C, C++, or other, would be best for programming micro controllers. What are the benefits of either one. I understand C is easier to learn but does that actually make it better? I need to use these micro controllers for sensor applications...

is it PHP-MySQL? In websites accounts of users tend to be stored in servers, and on these servers they store the data in some syntax and use PHP, RUBY or something else to add/change the information. Is it the same in bank accounts? In what format is banking information stored?

I am planning on learning a new language in the upcoming year. I already have a B1 level of french and had thought about perfecting it. However, I was told that German was more useful as a physicist as it would open career paths in Germany and postgrad opportunities after undergrad, the only...

I was having a morning look into assembly language videos and stuff and I was wondering: how much faster is assembly compared to some higher-level programming languages (like C or C++ or python)? And also why is it faster than those languages? I mean a general C++ source code should be...

In windows 10 when we are using a language can we use a different keyboard belonging to another language. For example can we use win 10 in English but can we use a French keyboard layout. Thank you.

Most physicists would agree, I believe, that mathematics is the language of physics. Mathematical models are used to describe the physical world. I therefore found it somewhat amusing but disconcerting that a recent paper found a statistically significant negative correlation between...

[Mentor's note: This thread started as a fork of https://www.physicsforums.com/threads/does-the-electron-really-spin-720-degrees.887917.] If you cannot translate the math to language, you are doing something very, very wrong. You are fundamentally at odds with the reality that physics is...

hi everyone, i was wondering if you guys had any textbook recommendations on the subject of assembly language (8088 and 8086) that focuses more on opcodes, register status tables, etc rather than programming in assembly. I have been using kip irvine assembly textbook but that focuses more on...

I'm currently writing a paper on the Multiverse. I do have a theory of my own and have made the outline and started working on it. However, the language seems to unscientific, in the sense, its not very objective and crisp. How do i improve the quality of language and content of the paper. Any...
