Summary: Research about the different vacuums used in labs and their applications. Hello, I am currently seeking assistance from people who work in labs. I am researching about the the different types of vacuums used in labs and their applications. Any information that you may have, please...

Hi all, I'm having a bit hard time performing error calculations on one of the lab results I got. The lab dealt with finding collection rate of a certain material onto a wire. While inside a vial, the wire was soaked in the material for a specific period of time. Then the wire was taken out of...

Summary:: How to do chemistry labs and demonstrations for online education. I am teaching two lab sessions one on general chemistry, one on organic chemistry. Now th we are going “online” I need a lot of help. Do you have videos showing labs?

Hi all! Like everyone else, our university physics department is prepping for online labs. We are utilizing great simulations from several sites, check them out below if you haven't already. We are able to rewrite many of our labs 1:1 conversion to online! Colorado PhETs...of course ...

Hello, I want to learn how to create virtual labs (html5, java and on) for physics education purposes. I could work on my own, but I am more interested in getting a solid background from experts. Is there any online course in which I could enroll? Thank you

i'm about to finish my first year of teaching. The district says that 40% of the ciricumlum is supposed to be "labs", but from what I've seen teachers pass as labs are more like activities. What do you consitiutes a lab versus an activity in a high school setting?

I'm a first year PhD student and the program I'm in requires three laboratory rotations. I have finished those and all three of the PI's explicitly said they want me to join their lab. I would consider joining 2/3 of them. I really like both PI's and the work they do (and the work they would let...

I tried looking for my unknown (209.70 g/mol) online and couldn't find it. The closest I found were H4O7V2(217.907 g/mol) and HCl2I(198.819 g/mol), but I know I am correct to a 2.7% accuracy. What other lists can I use to solve this?

Hi everyone, I work at a small high school that does one-on-one teaching with students who often have some kind of attention related learning difficulty or have trouble in a large classroom. The physics and chemistry courses I have been teaching have very inadequate lab sections and we have very...

Hi everyone, I am trying to understand that why do we use open circuit terminator for wave guides or any RF element such as coupler and etc. I know if we just leave it open, it does not work as open circuit. But why?

What do you guys think is the best area to be employed in? Depending on various degree levels, which area is better for undergraduates, graduates, or those who already obtained a degree? Which area is more helpful for getting into graduate school (if you're an undergrad) and which area has more...

I heard they sometimes need to use powerful computers or see the experiment and results.

A student asked if the labs need to be written in pen. Apparently, the lab instructions say to do so. Actually, I forgot that was in there. It’s kind of a hand-me-down set of instructions from ancient times (a few years ago). I should probably take it out, but it's worth a short discussion. The...

Hello, I am doing research for a story but my question pertains directly to Astronomy so I felt it fit here better than the sci-fi board. The main character is an Astronomer who works in a lab that receives data from the Dish in Parkes Australia. The lab she works at does not have a telescope...

Having taught physics for several years now, both algebra-based and calculus-based, and seeing what works and what doesn't in labs, I thought I would post some of my findings here in one place for your edification. 1. I am decidedly NOT a fan of what I call cookie-cutter, follow-the-recipe...

We're going to equip our fundamental physics labs: - Mechanics lab - Electricity and magnetism lab - Geometrical lab - Thermodynamics lab Which brand is qualified in your experience?

I just got out of my chemistry lab class at school, and needless to say, I don't think I am going to get a good grade. Basically, I felt like a complete idiot today. My professor was getting frustrated with me because he thinks I wasn't listening to him (even though I was). I never in my life...

I am taking an intro electrical circuits course which requires that I write extensive lab reports. I just completed a really simple lab about calculating resistance when configured in series and parallel, etc. In my intro I'm writing a short explanation about resistance, and resistors, and...

i'm not sure if this is the best place to post this so if its in the wrong place I'm sorry and ill try to move iti've always loved physics. I've never been good at much of anything except math and science. Never could play an instrument worth a damn, zero athletic ability, and so forth, but math...

Hey, Could someone please help me find a comprehensive source that might tell me anything about the functions of the following Labs (These Labs are found in an agricultural laboratory) Preparation room Mixer's Room Stability Analysis Lab Mineral Analysis Lab Chemical Storage Blood Analysis Lab...

If the question doesn't make sense how 'bout this one: "What chemicals should an amateur chemistry lab should have for experimentation?"

Hi all, I would like to know your opinion. I have been looking for a handheld multimeter online and I have encountered this company www.cnktechlabs.com. They are coming out with a new product - a handheld portable lab. The product looks very interesting. I was wondering would you consider...

I was just wondering what anyone has to say about doing graduate school for physics, but not wanting anything to do with the labs. Is is possible to go to grad school and do a phd without really getting too involved with lab work? I remember being in labs in physics 1 and 2 and I would...

Next semester I have registered for three basic, physics lab courses - mechanics, E&M, and optics. These will be the first labs I have ever done. I have purchased the lab manuals and read through the rules and procedures. I am slightly worried about the reports that I have to write during and...

Hello everyone, I'm in a bit of a predicament. I am a rising junior and I have realized that I would really like to transition to a different research group sometime in the near future. I have already received several offers from this research group in the past and have taken a graduate level...

What do you quantum experts think of this? http://www.technologyreview.com/view/514581/government-lab-reveals-quantum-internet-operated-continuously-for-over-two-years/ Link to the paper http://arxiv.org/abs/1305.0305

Problem: In beginning mechanics physics labs, it is very often the case that you get large experimental error. This can be due to a number of factors, friction, of course, being a major player. However, it can also be the case that you might be comparing apples to oranges. For example, if you're...

So I'm student teaching right now in a poor school with a physics program less than 3 years old. The lab equipment is not great. So I'm trying to set up a lab on forces, friction, etc... but there is not a lot of the stuff I'm used to using like the tape timers to measure acceleration. But...

Dear All, I have read many threads on second careers including the excellent blog by ZapperZ "So you want to be a physicist" and then reaching out to you all for guidance. First, a brief introduction on myself: Industry Experience:  I am a US Citizen based out of the Northern NJ/ NY...

Hey all, I'm starting my search for mechanical engineering grad schools and I could use a few suggestions. Just, so you know a bit about me, my current niche is in energy and I have experience in combustion research, but I've also always been interested in space-related work. Maybe I could even...

Hello, In my chemistry and physics classes and I severely lacking. On the whole, I am good at the theoretical work in these classes, i.e. my tests scores are a lot above the average, however, when it comes to doing labs, I just can't for the life of me figure out what's going on. It seems like I...

For the past couple of years I've been having trouble in my physics and chemistry labs. Not horrible trouble - I still get good grades and understand what's going on. But everything seems to be 10 times more painful for me than everyone else... I can figure out what should be done next, and...

I have a Group Lab due on Tuesday and I have not yet heard from anyone. I tend to think that most people aren't as serious about their grade as I am, so this is pretty annoying to me. Should I just do the lab myself, just in case? I have already finished my part of the lab, and I simply won't...

I know that it's technically not allowed. But some professors allow (and even encourage) motivated individuals to do it anyways. In any case, has anyone else done this? I'm considering doing this after I graduate, as there are some labs I really want to take (they're mostly computer labs). Of...

Sorry if this question seems incredibly ignorant. Anyway, my quick question is what is the structure of a national lab (in the US). I'm familiar with the traditional university model (grad students = cheap labor, post docs = better cheap labor, professors, etc), but how do national labs...

What are everyone's thoughts on their undergrad labs (especially) for Physics? Do you like them, find them interesting or exactly the opposite? How are they conducted, what do you do? I am asking these questions, because in my first semester the lab was the most dreaded part of going to...

I will be going to university next year and I've really fell in love with the idea of working somewhere like the old Bell Labs. What I want to know is... Is there a modern day equivalent to Bell Labs (anywhere in the world) or have I created an unattainable dream, rooted in a long forgotten...

Are employees of national labs considered "federal workers"? With the recent news that most federal workers are likely to be under a pay freeze for the next 2 years, I was wondering if employees of national labs fall under this umbrella.

What do I do if I have a hard time contributing in labs? Everytime my professor tells us to work together on a lab, I always walk away feeling like it was a wasted learning experience because I couldn't contribute. Additionally, labs are hard for me because there seems to be a huge mentality of...

Have there been any studies done as to which is more effective as supplements to teaching introductory physics courses, labs or recitations? I've been having discussions with a fellow grad student who has never taught a intro physics lab about their effectiveness and also with a professor who...

I teach High School Chemistry and Physics in a low income area. I have grown to become a skeptic in the over all value in labs. I do see them as a way to mix up the class and make it more interesting from the perspective of changing up the scenery. However, I am not convinced that students...

Hi everyone, I'm planning to major in chemistry double minoring in physics and math. Next year I'm registered for a full course load (5 courses) each comes with a lab 3 hours long (except one which is 2hrs). These are all second year courses and they cover material I've never heard of. The...

I'm currently attending U of I and majoring in Nuclear engineering, following in my fathers foot steps, and here i arrive at the problem my father is a nuclear engineer like i have said above and works at a nuclear power plant, and seeing what he goes through working at a power plant I'm sure...

Kind of a stupid question but I'm very interested to know. I would think business casual but a lot of the pictures I see online of people working in labs are wearing ordinary close (jeans and such). So if you were a grad student going to visit a lab for a few days what would you wear?

From what I've seen, most of the threads concerning jobs after receiving a PhD in physics focus on professorships. But I haven't seen too much about working in national labs and industry. So here are a few things I've been wondering about myself: How hard is it to get a job in industry? In...

I was just curious about knowing a few specific names of companies and labs that hire physicist. So can anybody list a few? Thanks!

I did a bit of x-ray spectroscopy in labs studying Fluorescence of some different elements. I was just wondering whether or not flourescence occurs in all elements? I'm sure I've read people talking about 'flourescecnt materials' or something like that. I can't think of any reason why it...

Hi, I was recently accepted into two summer programs. One, an REU at U Chicago and two, an internship at the Lawrence Berkeley National Labs. A friend of mine says that the National Lab internship is more prestigious, that is, that the mentors are slightly more amazing at the National Lab. Is...
