Hi all, I got a BA in Physics, and am almost a year out of school. I have noticed whilst perusing graduate school websites that most emphasize that they want letters of recommendation from academic settings. I landed an internship in R&D after school, and I was wondering how...

Hello PF. I am looking for a recommendation of some HTML5 guide I can get online. I have no knowledge on PHP, HTML, etc. but I do have lots of programming knowledge in Java and some in .NET. So what guide do you guys recommend? Thanks.

Would you guys recommend the following Book By Paul Cohen as a good (and cheap) intro to set theory and the Continuum Hypothesis. Set Theory and the Continuum Hypothesis (Dover Books on Mathematics) Some reviewers attacked Mr. Cohen as being a poor logician. Maybe people were just mad...

Can someone please recommend a linear algebra book that will be more visual friendly. I like to understand the concepts visually and the book that my class is using doesn't fit me too well. I am using Elementary Linear Algebra by Spence and Friedberg.

Hi everyone, Long time lurker, first time poster! I'm developing a website where users can read and participate in discussions, articles and questions. I'm currently developing an algorithm that will recommend to each user discussions, articles and questions that they would be interested in...

I am trying to apply to chemical engineering REU's for the summer, and I have one physics professor that said he would write a letter for me, but none of my chemistry professors have responded to my e-mails asking if they would write one. Is math a close enough field to get a letter of...

When applying as a transfer to a 4-year college from community college, is there anything detrimental about this? I don't want to be insulting and ask him to get someone to proof read his letter of recommendation, but he's not exactly a Nobel laureate or NAS member so I'm afraid if his letter is...

A few months back, I asked four of my professors to write me letters for grad school. They all agreed, and to date three of those letters have been submitted. However, the last professor is still tardy on his letter, and it's already way past the due date. I'd like some advice here: Since...

I am currently a first year graduate student in math, and I am trying to pick a linear algebra book to work through during the winter break. I have already gone through the computational style linear algebra, and I have also gone through Axler's Linear Algebra Done Right. I would like to go...

Hello MHB. I want to read an advanced combinatorics book. I am well versed in combinatorial methods like counting proofs, Pigeon Hole Principle, criticality, induction, graphs etc. I have good knowledge of undergraduate algebra so I am fine if the book you recommend has some algebraic methods...

I believe I've procured 4 professors/advisers to write recommendation letters for me for my grad school applications. It just so happens that 3 are active in my research area of interest, but I have a really strong friendship with 4th one as I've known him the longest (freshman physics...

I have decent understanding of GR/SR explanation of our universe's laws, however I feel that the theory basic concepts and imply complications which are making simple problems (like twin paradox) appear more complicated than they should. I understand that there are alternate theories that do...

I'm worried about not havin the strongest sources of letters when I am applying to graduate school. I'm wanting to apply in math. I have one math prof that I know can write me a strong one. We have such a small department though, just 3 profs. One professor is so spastic and odd that I'm not...

Hello, I'm trying to read a paper titled "Cluster Identification in Nearest Neighbor Graphs". It's a mixture of probability, graph theory, and topology. I'm having difficulty interpreting some of the ideas, specially when it comes to k nearest neighbor graphs. I've been trying to look for a...

Next semester I will be taking Calculus 2. I have used Courant and a little of Spivak for Calculus 1, and loved it! Extremely complete and challenging. Great books. So, this is exactly what I will need to know: Ordinary differential equations Families of equations, initial value...

I need some example driven learning material for my "singular perturbation" class. Someone help me please.

If such a thing exists, what is a good popular science book for quantum mechanics? Multiple book choices would be accepted. Not looking for textbooks, more something you can lend to people who don't have science degrees but who are keenly interested in the subject. In an ideal world it...

I'm currently using Electronic devices and circuits by boylestad. My problem is that there aren't much examples about clippers and clampers, and it only uses ideal diodes and there is only one diode per circuit. Is there any book which has a good chapter about those devices. It should contain...

Heya Everybody, I've gots me sum boat loads of noisy spectroscopic data dat I've gots to sort thru. It's been a while since I've had to jackknife, bootstrap, or weiner filter anything. Can anyone recommend a book for refreshering me memory on these subjects? And any other techniques for...

Hi, I was wondering if you can suggest good books on the techniques for mathematical proofs. I know this is quite a simple matter but I would be glad if you could suggest me with greats books for teaching proofs. More often than not I used the direct method and induction to prove problems in...

I'll be taking PDE this coming Fall semester, and I want to have a head start by doing some self studying this summer. What's a good textbook you would recommend for PDE? (the official textbook in my university is "Beginning Partial Differential Equations" by Peter O'Neil but I've heard...

Would anyone recommend some books for me to learn about thermodynamics and optics. I was stuck on choosing books since either of them are too difficult or a little bit simple. I don't where I should post,I am apologize for any inconvenient cause.

Lookin' for a good text on Advanced Calculus for self-study. Thanks.

As the title suggests, I'm looking for a good text on Advanced Calculus for self-study. Thanks.

Right now I have Schroeder, and I'm not a fan of it, despite some of the rave reviews I have read. I'm thinking I need another text to learn from while taking this class. I have a copy of Fermi's Thermodynamics (somewhere), but I'm not exactly sure what's in it. I just think it's silly that I'm...

I understand the importance of letters of recommendation for grad school applications. My question is: ideally, how much should my recommender know about me? I ask this because I study in a top, big research school in which the interaction between the undergrad researcher and the PI is very...

I've posted here before about how I dislike my physics teacher for various reasons. He ignores kids' questions, and he mostly talks about sports, or makes pop culture references and jokes just to get laughs from the class. No one thinks he is a good teacher, and he focuses more on his football...

I was wondering if anyone could recommend a good simulator to play around with. I'm a chem student and have always wanted my own lab, but having one is expensive and potentially dangerous considering I am still living at home. But i would like to play around with a simulator, preferably a free...

I'm in an introductory analysis course, and next quarter we're doing multi-dimensional analysis. So far, we've done single variables and I've done well with Spivak's Calculus. However, next quarter, we're using this book: [1] https://www.amazon.com/dp/0130652652/?tag=pfamazon01-20 Based on...

Hi all, Every now and again I make my way to these forums, and I finally have a question/discussion I'd like to start. Can anyone provide some recommendations on a good, quality desk for prolonged periods of study? I am looking for something with lots of space, i.e. it can support...

I am currently applying to some REU's in math, and I need two letters of recommendation for just about very application. I have one professor whom I have had for three courses and received an A+ in each one and he knows me quite well, so I expect a pretty good recommendation from him. However...

Hi, I need two book recommendations for each of the following, one classical (i.e. covers the subject in detail, more like a reference, and influential if such book exists) and one as a quick study material. The topics:- 1) Algebra 2) Geometry 3) Trigonometry 4) Calculus Thanks.

It has been awhile since I've posted. :rolleyes: Anyways... I'd like to start learning multivariate calculus along with linear algebra. However, I have a little problem in choosing a suitable text. I'd like to have a text with more theory and less applications. Some people have recommend...

I've came across a book about topolgy, Topology Without Tears by Sidney A. Morris. It can be found here: http://uob-community.ballarat.edu.au/~smorris/topology.htm The explanations are rather clear and an outline of the proof is given before each proof. However, many quite important concepts...

I'm starting my first math class that involves Fourier analysis. The book we are using is Boyce and Diprima's Elementary Differential Equations and Boundary Value Problems. I find the examples helpful but I have a hard time grasping the conceptual sections. Any recommendations for good intro...

I have little experience of mechanics and I need to simulate an iron cylindrical cantilever beam with a length of 160mm and diameter of 36mm. I need to find the points on the beam where I can place a full-bridge strain gauge circuit and get the strongest signal. Ideally I want to have an actual...

Hi can someone please recommend a strain gauge to measure mass flow rate of a pneumatic conveying system. The full bridge circuit strain gauges are to be placed on a cylindrical cantilever beam with a length of roughly 160-170mm and a diameter of 36mm and made of iron. From what I have read...

I'm looking for a piece of software that could assist in developing a schematic of an optics setup with train traces. Doesn't have to be fantastically involved (ie cheap/free is best), but I'm finding that drawing and updating lines in 2d solidworks gets tedious (unless I program tons of...

I plan on applying for an REU program this summer. I know my research mentor will write a very good recommendation, and is well-known in the field. However, I have no other connections. The applications are due in March, so I think I shouldn't place too much stock in next semester's...

Hello, If I had to choose between the two, which do you think is better for a letter of recommendation? (it's for applying to a graduate school, coming from an undergraduate in physics) 1) A PhD student that I interacted with on a daily basis during a two-week undergraduate research period...
