I have interviews as a physics lab assistant and lab apprenticeship

Click For Summary

Discussion Overview

The discussion revolves around preparing for interviews as a lab assistant and lab apprentice in physics laboratories. Participants share resources and advice on reviewing lab devices and equipment relevant to undergraduate physics labs, with a focus on the challenges faced by the original poster in recalling past experiences and understanding the specific requirements of different educational systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • The original poster seeks sources on lab devices to review before interviews, expressing concern about not having access to old materials.
  • One participant questions the vagueness of "lab devices" and suggests clarifying whether basic instruments or specific types of equipment are needed.
  • Another participant recommends checking online syllabi for the lab classes to understand the types of experiments and equipment involved.
  • There is a suggestion to familiarize oneself with motion measuring setups and electronics lab equipment, such as oscilloscopes and signal generators.
  • The original poster shares their educational background, noting a lack of recent lab experience and uncertainty about the specific labs they will be working with.
  • One participant advises reaching out to the universities for detailed course descriptions if not available online.
  • Another participant suggests looking at various lab manuals from different schools to understand common themes and approaches in physics labs.
  • A historical perspective is provided by a participant who shares their past experience as a lab assistant, emphasizing the importance of understanding experiments from a student's perspective.
  • One participant lists three lecture courses from Indian universities that cover undergraduate laboratory work, suggesting reviewing them to refresh knowledge of devices used.

Areas of Agreement / Disagreement

Participants generally agree on the importance of understanding the types of equipment and experiments relevant to the interviews. However, there is no consensus on specific resources or the exact nature of the lab devices needed, reflecting a variety of perspectives and experiences.

Contextual Notes

Participants express uncertainty regarding the specific labs and equipment due to differences in educational systems and a lack of detailed information from the universities. The original poster has not engaged in lab work since 2016, adding to their apprehension.

Hello All :

in the near future i will have few interviews as lab assistance and lab apprenticeship , mainly physics labs , do anyone have a source on lab devices to review before the interviews ? maybe i won't be able to find all my old books or internet links

Best Regards

<<Emphasis added>> "Lab devices", even with the delimiter of "mainly physics labs", is waaay too vague. Are you talking about basic instruments such as computers, voltmeters, and micrometers? Otherwise, instrumentation will vary significantly with the specific lab (e.g., materials analysis vs. particle accelerator). Please clarify your question and what your goal is.

mainly 1st or 2nd year undergraduate physics laboratory for one interview
 
Can you look at the online syllabus for each of the lab classes that you would be working with? That should give you some idea of the types of experiments they do and what kind of equipment is likely involved.

Do you have experience with motion measuring video setups and software? Even cellphones can be used to track motion in ball-down-ramp and projectile motion labs.

Do you think you will be helping in electronics labs for these physics classes? If so, it would be good to find out what equipment they use (oscilloscopes, signal generators, etc.), and familiarize yourself with them (download their online manuals, for example).

Your profile is not clear on your background and current status. Did you complete a bachelor's in physics? If so, how long ago? Are you applying for a position at a university different from the one you attended?
 
i completed a BSc. in physics years ago maybe 2008 or 2009 i don't remember exactly (always forget this date :) ) the position is in a different university and in a different country

about why i have no idea because it is different educational system and no mention what's so ever on what lab , but i form an impression it is maybe 1st , or 2nd year lab which is more a general physics labs , but there is a lot of equipment and even huge number of setups and frankly i didnt do labs since 2016

the other lab is in the united state , i filled the papers and emailed them waiting for their response , no mention also on the labs

In that case, if the university does not have a detailed course description on their website, I would reach out to your contact at the university and request a detailed course description in advance of your interview. If [when (I hope) :smile:] the US university responds and arranges for an interview, do the same there. Good luck!

Aside from specifics from the universities where you have applied,
it might be a good idea to look at lab manuals from different schools
https://www.google.com/search?q=physics+lab+manual

Some are more elaborate than others, some are more hand-holding, etc...
... but you can get a sense of some common themes, as well as the variety of approaches.

Detailed "lab setups" are particular to the equipment at each place.
No one is expecting you to know how they are all set-up.
(That comes with experience.)
But it's probably more important to know how one could set it up.In particular, it might be much more important to understand:
the point of each lab (as part of a set of labs for that course),
what is being measured,
how it's being measured (and why is it measured in that way, and not some other way),
and how it's being analyzed
(taking into account
the preparation of the student
and the faculty's goal for that student's experience).

I was a lab assistance at my university back in the '70s and what I had to do was to do the experiments just like the students were asked to do. I believe the harder task was the grading part. Good luck.

Here are three lecture courses covering almost all undergraduate laboratory work, at least according to the syllabi in Indian universities:

Experimental Physics I

Experimental Physics II

Experimental Physics III

It's definitely too much to go through all the videos, but you can at least look through the list and see if you remember the devices, and if not, you can go through the video. (When I need to go through these videos, I generally increase the speed to 2x, otherwise they become too boring.)
