"Deriving" the Schrödinger Equation Using the Momentum and Energy Operators
In this video, I explain how to "derive" the Schrödinger equation, although a derivation from first principles is impossible. For that purpose, I derive and make use of two important operators in quantum mechanics, namely the momentum and energy operators that are derivatives of the wave function with respect to the position and time.

Polar Form of Complex Numbers & Gauss Planes
Просмотров 426Год назад
In this video, I explain how to convert complex numbers from the Cartesian form into the polar form. This conversion includes the calculation of the absolute value (radius) of the complex number and the angle. Furthermore, I introduce Gauss planes using a Cartesian coordinate system, which is a helpful tool to illustrate complex numbers. - - -Physics Tutorials- - - This series covers many examp...

LaTeX Tutorial 13: Drawings in Latex with TIKZ
I love this phenomenon. I woke one morning in my dark room, saw a bead of light coming through my curtain. I stared at the circle of light on the ceiling and realized it was changing colors, i was confused. I focused closer and saw it was project the images of people walking on the sidewalk outside, i could see the bottoms of their legs and their shoes, even the grass. I was obsessed with that for a while lol
Which is this place?
Please continue this series!!!!
c++ interpreter, huh? reminds me of temple os' "holy c" interpreter. i like it!
THANK YOU VERY MUCH. I tried this 3days but you solved this only 3 hours!!!!!!!!!!!!!!!!!!!!!!!☺☺☺☺☺☺☺☺☺
Hi There. I after running this code, my GL is very slow and responds with a significant delay. What is the real problem. Would the multithreading solve it? HP Envy x360 with Core: 12 Memory :512GB SSD RAM : 16GB DDR 4 3200MHz Processor: Intel core 7 Graphic Card: Intel Graphics
Thanks a lot, your video helped me.
Thank you sir for making this tutorial. When I run the make command, I get the error given below.

how did the footnote command without using fancy package?
you are the best , i deeply appreciate your direct and clear information
Nice job, thanks. The video inset of you hides an important part of the demo. Any way to fix that?
isFinal() is the key
I did everything as mentioned but after the command make -j4 the process is stuck at 63% and there are a few errors as well. What can be done to solve this issue? c++: fatal error: Killed signal terminated program cc1plus compilation terminated.
If anyone else is facing the same problem. Try using less cores to build root. eg. in place of "make -j4" write "make -j2".
Hi! I have added both Optical interactions just as you did, but still I cannot see any phtons, so to speak cherenkov light.
Got it fixed. The header file G4OpticalPhysics.hh in the repository of geant4 does not contain the cherenkov process defined in it. I used an extended version of the G4OpticalPhysics.hh which has Cherenkov process defined and it worked.

When installing, the command shell showed this: [ 61%] Built target obj.clangFrontend make: *** [Makefile:156: all] Error 2 Anyone can help?

Sir, can that Photons->Draw(...) command be used for some other particles too?
WOW well explained
Amazing video! Is there a way to change the color for each graph in the HStack?
I am trying to follow the tutorial but I am getting this error: CMake Error: The source directory does not appear to contain CMakeLists.txt How can I solve it?
thanks a lot from somebody who's very new to this. The video was very easy helpful. I would like to know what i should do like if i was plotting it from another root file and has to draw a specific variable from the branch?
Forever grateful for your videos!!
Thank you for the tutorial! It saved my life!!! 🙏🏻
Thank you
I don’t know how to thank you enough for your work. If you have a Patreon accout, please let us know.
great tutorial!!!
Kindly make a vedio on how to install fluka software on Ubuntu.
Is it possible to use geant4 on windows system?
yeah man. I mean. I searched in so many reddit and blog posts. And your Video is like too easy and functional. Much love
CHADDDDDD
Is there any way to download this code on Windows?
how do you write letters with tildas on top in your Laptop?
22:11 is it a energy spectrum?
What program is this?? looks like tikzit
need to add a return value in function ProcessHits, or it will cause illegal hardware instruction core dumped error with gcc 14.1.1 in Arch Linux. Seems that ubuntu does not have the issue, maybe it's caused by gcc version?
For those who can't find output.root in the build folder:- follow the video till 17:30. In my case root file was created no before it was filled with entries.
That was super useful
Thanks a lot
Very good video, thank you very much! However, as seen in the gamma spectrum of 60Co, the photopeaks align very well, but the Compton background wasn't recorded properly (or at least not completely). Does anyone know how to achieve a better recording of Compton scattering?
Nice video. One remark: you forgot to close the file.
For those who have problems using G4PhysicsOrderedFreeVector, use G4PhysicsFreeVector instead, i think it changed for 11 version. Also there is no spline() function so i erased that line and it worked for me.
How to make "Contents" set in center?
My treshold for the activity 1 is 2GeV. Even at 1.9999GeV there is no Cherenkov light. For the second activity, applying the next macro /gun/position 10 10 10 cm displace the mean value by 10.
Really useful thank you
I am not being able to get the output root file. Is there a solution for that?
Thanks for the video it was very helpful! Have you uploaded any more videos about the ATLAS software? Because it seems like the playlist ends with this first video.
This instalation won't allow you to use your HDD on windows so it's kinda useless you have root on windows but you cant put data in it or even take data from your HDD.
Thank you for making this video! it helped me understand more about how geant4 works!
