I'm writing a large amount of data to a binary file. Trouble is, I don't know how much until the program finishes executing. Given this, I'd like to rewind back to the beginning of the binary file and write an element indicating how many records I wrote to the binary file - this way I can...

Hi! for (int i=0; i<=9; i++) { for (int j=0; j<i; j++) cout << " "; for (int j=i; j<=9; j++) cout << "*" cout << endl; } Can anyone explain me what these lines are doing? Thank you!

after reading the FAQ on how phonons, or modes of vibrations, are responsible for the slowing down of photons in dense materials, i still have some unanswered questions: i visualise phonons as something like qualities of a field, because they coordinate the deviant behavior of individual...

I wasn't sure whether to put this in S&D, but here we go. I've found that I have a really strange ability to tell what people are feeling/thinking. It doesn't occur with everyone, sometimes it happens straight away, sometimes after I have known them for a while. Often I meet someone and just...

i was doing some reading on Newton's law of universal gravitation. the equation is given as mass of 2 objects divided by distances square and then multiply by gravitation constant. using 50kg and 100 kg mass and a distance of 2 metres i get a value 8.34e-8 N this a small force, which sets me...

Hi new here, I'm getting into this field of theoretical physics, and I have a goal to read several books over the summer. Currently reading Brief History of Time I guess because of its popularity. here is the list A Brief History of Time by Stephen Hawking Hyperspace by Michio Kaku...

So, what are you currently reading? Is it good? Bad? I'm currently reading "God in the Equation" by Powell. It's alright I guess. I haven't read a Physics/Cosmology book in a long time so it's ok. I would read two of them in a row. Since I'm almost done I'll be looking for another...

[SIZE="3"][FONT="Book Antiqua"]As I was reading about photons, Some of the information was puzzeling for like; photons have no mass or that they don't have a kinetic energy. I understood having a zero mass at rest but when traveing with the speed of light the photons should gain a mass ( I...

I was reading about the ID/Evolution conflict and saw some of the arguments aginst evolution. Some of them were pretty convincing: 1) I the first human on the moon would find a clock, no one would believe that the clock got there "by chance", it'd be easier to believe that aliens (or the...

what is your reading speed?? And if by the way,it is high..what factors are responsible for that.. Have you ever seen anyone having a reading speed of 3000 or more than that...i don't know how that's possible,,doesn't it mean the person has enormous control over his mind..

If i have a barometer which reads 76cm of hg when kept in an elevator when the elevator is at rest . now the elevator starts going up with some acceleration . will the barometer read less than , greater than or equal to 76cm of hg . also explain why . what will happen if the barometer is under...

I was wondering why Henry Moseley ploted \sqrt{f} vs. Z instead of just f vs. Z. I'm guessing it is because this way, the graph of \sqrt{f} vs. Z would be linear? But if it was just f vs. Z, wouldn't the equation just be exponential? Also, what is the significance of the L seriese and the K...

hello everyone, this is my first post on these forums. yesterday i was at the local B&N and bought stephen hawkings "a brief history of time". I've never taken a physics course, though I've wanted to in past semesters(without calculus) but it has always interested me. in the space-time chapter i...

When was reading about renormalization I did no understand the main Idea of the last :(:confused: It has been considered photon propagator with virtual pair of electron/pozitron. Takeing that loop integral the M^2 cuttoff is introduced, which tends then to ininifity, M^2 is "sopped up" in...

i was reading simon singh's the code book. it describes different systems of cryptography. but what i wanted to know was how to 'crack' different ciphers. can any suggest anything i can read. thanks to anyone who can help.

My ability to scan left-to-right surpasses that of scanning right-to-left. Could this phenomenon be substantially brain based, my having learned (neurologically developed) to read left-to-right? Do peoples who differ in direction of reading differ substantially in brain structure, like a...

hey everyone, I'm going to be starting my first year as a physics major, I was wondering if there were any books that anyone would recommend, textbook or othereise that I check out. I was thinking about getting the Feynman Lecture on Physics. Any suggestions? Thanks :smile: dleacock

I have to read a list of strings in from stdin and store them, stopping when a blank line is entered. Here's what I tried... const int LINE_CAP = 100; const int MAX_LENGTH = 80; char *strings[LINE_CAP]; int strings_index = 0; char buffer[MAX_LENGTH]...

urgent help needed http://www.physik3.gwdg.de/~rgeisle/nld/sbsl-howto.html Halway down that page is a circuit diagram. In the diagram wires don't lead to anywere(after the resister label R1 the wire doesn't go anywere), I don't that much about reading circuit diagrams but I know those wires...

I have a problem with reading... I notice that most lighting in combination with my books/textbooks really generates an awful glare. I know I can just tilt the book.. but in the case of a larger textbook this is often a problem (even if I put something underneath to tilt it). Anyone know of any...

During a physics prac today, we were using a traveling microscope with a vernier scale. My demonstrator told me I was reading the scale wrong, and as much as I tried to convince him otherwise he insisted he was right. Can anyone here tell me what the correct value to be read from the vernier...

Tell us what book(s) you have read recently and what you think about them. Be sure to add in whether or not you think it is a specialized taste that will enjoy a title or if you personally don't like a particular book but think others might. And try not to give away surprises!

Hi, I've come across some problems while reading a mathematics books. 1. The first problem is: \int \max (1, x ^ 2) dx My answer is: x + C, |x| \leq 1 \frac{x ^ 3}{3} + C, |x| > 1 But the book does not seem to agree with me. It reads: x + C, |x| \leq 1 \frac{x ^ 3}{3} +\frac{2}{3}...

Hi, I am just getting into building circuits. I have found a nice page with all the symbols: http://library.thinkquest.org/10784/circuit_symbols.html which has helped me some but I still get confused. The circuit I am talking in regards to is this...

I'm not sure where this thread would go, but here it is... I am reading about the property of satisfiability. And trying to get some things straight. I saw different kinds of logics (porpositional, relational) being tested for satisfiability. I've read about models and formal systems. The...

reading Smythe's book on "static and dynamic electricity" Hi, I am reading Smythe's book on "static and dynamic electricity" (1st edition, 1939) and I'm having trouble deriving some of the formulas. I wonder if someone already corrected that. For instance, 1.10 - Gauss's electric flux...

My hair is cut short enough so that it's pretty much straight, like a wiffle only longer, and the other day I was sitting waiting for the bus in the late afternoon and reading a book (the Medea). The sun was behind me and the hair on my head cast a shadow onto the book. As I turned my head...

hi all, i've taken a junior level QM course using griffith's introduction to QM text. I've been wanting to review and broaden my exposure to quantum mechanics a bit over summer and was wondering if anyone could recommend any texts they've found to be excellent. currently I'm looking to read...

Hi Ho! ^^v I know that open source software can be reworked by many people. Because of that, it grows rapidly. Frankly, I wonder how people can rework it if they don't have a good technique in reading the source code. When reading Emacs source code, I really confused from where I should...

How can i read file data into 2d vector ?thanks

"Principia Mathematica" worth "reading"? Hi everybody, I have read about Principia Mathematica in many books, and sites on the Net, so I would like to ask you if you know anything about it,or even read some parts of it. What is it exactly ? Is this really important? I read that Godel has...

Whats in your bathroom Library? Mine has the last 3 issues of National Geographic, several old copies of Hotrod mag., the Michigan state campground guide and several superhero comic books.

the question on my mind is whether, if we start trying to understand hep-th/0502106 will we occasionally get help from people who understand it better and who might look in sometimes? this is something we cannot tell in advance and it depends to some extent on how capable we are on our own...

Just a general question. I've been reading books generally these days, whether it be general literature or science textbooks. What is strange (or not) is that i have come to prefer black and white books rather than colour books. Actually, I'd come as far to say that colour books sometimes...

Hello everyone, I am searching for a whole course on undergraduate Astrophysics which cover some topics like: formation of stars/accretion disk/hertzsprung russel diagram/ energy transport and generation in stars etc.. I have been searching only to coming up with some course either very...

Sorry for this little rant, If the iPod ear bud wires were black would there be so many people walking around and just showing off. Another thing is,how many of you can read book in bus or subway and learn and remember anything,I can't.Some people of course like to to read on public...

I have gained an interest in learning a bit of the existential attitude and would like to hear if anyone has recommended readings. So far I've read papers by Sarte, Kierkegaard, Nietzshe and Husserl. Thanks!

I am a sophomore in high school, and am becoming very interested in physics. It started when I was young and did a report on Albert Einstein, but is just now blossoming. I'm intrigued by nearly all areas of physics, and have just now begun to further my knowledge. I've read Beyond Einstein and...

Hello, I was wondering if anybody could lead me to some online reading about Quantum Mechanics and its history? Thanks.

I know this isn't exactly an English forum, but many of the members here do know quite a bit about English and reading. I find that when I'm reading something I automatically start hearing the words in my head. I feel this is slowing down my reading speed, is there any way for me to start...

This is another problem I am having troubles with. Here's the prompt: What is the reading of a voltmeter with the proper range and with resistance 5*10^4 Ohms when connected between point b and ground? I know that for voltmeters, V = I_fs (R_c + R_s), and I tried solving for V using the...

i'm reading a programming book and one of the problems it asks me to solve is to write a program that determines the larger and smaller values of two integers that the user inputs. I could not use if statements in the program. I checked the answer and they had used this expression to come...

I'm new to this stuff, so the question may be really simple, but I just can't work it right... Alright, so the question I'm trying to figure is this: The student's normal weight is 500 N. He stands on a scale in an elevator and records the scale reading as a function of time. So for the...

Q: I am reading up on voltage and I want to make sure I am understanding this concept correctly. We say that there is a voltage between two points a and b. Then if I am to put a particle of any charge at point a, and multiply the charge by the voltage, I will obtain the potential energy at point...

Hey all. I was wondering how most people learn how to read schematics of electrical circuits and such (apologies for the undoubtably inaccurate terminology, I'm ignorant of these subjects). I understand some very very very basic fundamentals about electricity, mostly garnered from various...

does anyone know what an ORF (open reading frame) is? it would help me a lot if anyone explains this to me. thank you so much!

somebody got a transcript of Hawking's 21 July talk at dublin to the blogger/cosmologist and generally cool guy Sean Carroll and Peter Woit, the mathematician blogger of Columbia U and Not Even Wrong fame, passed the link on to us http://pancake.uchicago.edu/%7Ecarroll/hawkingdublin.txt...

The assignment states: "Write a code fragment that reads and discards all characters from standard input until it encounters a "=", and then reads the following characters as an int." I have a couple of problems: 1) reading char values as int, for instance if I input abc=123 there's no...
