I am trying to search on other sensors for accelerograph but the thing is that I can only seem to find that it only uses accelerometer. Are there any sensors that is beyond capable of accelerometer in seismic detection application?

I came upon fiber optic but the thing is that fiber optic cable is that it is installed underground to detect seismic activities. I am thinking of sensors that can be deployed or be installed in just surface level like a normal accelerograph does.

Heys guys,

Has anyone made a project about thin film simulation using monte carlo method. Or any other thing related to thin films.

HELP

A few years ago we held a graduate student panel, where many recently accepted grad students answered questions about the application process. That thread is here, and has a lot of great information in it.

This is overwhelmingly the case at my school. Not to bash the physics profs. They are all very smart and talented. But the vibe of my physics department is very much "Doing physics is serious business". All my math classes (at least once you get past calc 4 and start taking higher math) are just like "math is fun!". All the math profs are super kind and open and feel like my friends, even if I don't actually know them very well (I'm a physics major). Which I can unfortunately say has almost never been the case in my physics classes.

This came up in a chat with my physics friends recently and I just had to ask if it was the same experience for others.

I rarely delve into Computer Algebra Systems (CAS), but when I do, I want it to be reliable. I've often turned to Mathematica in the past, but I find its user interface to be pretty unintuitive. My encounters with MATLAB during my undergrad days didn't leave me with fond memories either.

Today, I stumbled upon Julia's "Symbolics" library. What caught my attention immediately was its open-source nature and the ease with which I could script and utilize it from the shell. However, I couldn't help but notice, purely by intuition, that it appeared to be on the slower side.

Now, I'm curious to know: What's your go-to program for handling CAS tasks?

I don’t think I’m alone as a student that hasn’t decided on a specific field of research, so I thought it would be interesting to hear from those in research about their field of study and why someone should consider entering it.

Additionally, what’s one thing that fascinates you about your field, and what’s the biggest unsolved problem that your field of study faces?

Hello /r/Physics.

It's everyone's favorite day of the week, again. Time to share (or rant about) how your research/work/studying is going and what you're working on this week.

I downloaded an app that has a bunch of physics related items in it (magnetometer, compass, etc.). One of the items is a spectrogram/spectrum analyzer. Ever since I've had it, I've virtually always had a constant low decibel (~-85dB) 9.8 kHz tone. It's almost always strongest at home. However, I've picked it up more faintly even out in the middle of nature near my home.

I've popped it on a couple of times at work, however, I have not seen that tone while at work.

I have seen it fluctuate between nearly 10kHz and closer to 9.2kHz, but never ocillating around, always a constant tone. I've also noticed that sometimes it has a "pulse", as seen very faintly in the attached image. Screen shot was taken while phone was laying on my computer desk, not moving.

I'm very curious as to what could possibly be causing this, even out in an area without any housing nearby. Google searches have come up empty.

Thanks in advance for any light you may be able to shed on this!

Has anyone used it to actually calculate something because I\m having a problem at actually creating useful circuits without creating an error. What have you used it for?

Also it seems I can make circuits that give different results for the same calculation. So what's up with that, is it just an optimisation algo finder?
