please Y axes contians what , in the root file fEdep ???

i have a error in this line gr->SetMarkerStyle(kfullCircle); what happened)

Following along up to 7:17. Forgot to turn 60Co momentum to 0 GeV, left it at 100 GeV by accident. Boy was that interesting to look at XD

Hello Dear i get following message while running example "/usr/bin/ld: /home/vboxuser/geant4/geant4-v11.2.2/lib/libg4processes.so: undefined reference to `g4incl::binarycollisionavatar::cutnnsquared'". Can you help me?

Thank you so much for this detail explanation. Could you have this video for Window 10, please?

absolutely disgusting sniffing

The best video to install Geant4!! Thank you so much!! 😇💞

I'll give thumbs up for using Linux MInt

Thank you it is an excellent tutorial, very helpful !

Thank you! Is it possible to make it for Cf252 spontaneous fission?

can you please make a tutorial on ttbar process generation .

Hello, while running your code with in the same version, I get a lot of random numbers and only one line saying: Segmentation Fault. Any tips on how to fix this?

thanks this is great

Is it possible to plot a contour map of a city using python?

Thanks

Thanks for the video. It was amazing. However, when I run these codes to my macos, I don't see the live buildup of gaussian distribution, rather I see that the code runs first and then root prompt comes at the end with the final drawing of the canvas. Any idea?

Thank you for these tutorials! They're super helpful. I really wanted to enhance my CV and came across your videos. Can I ask a few questions... If I want to avoid the default new paragraph indentation, do I have to repeatedly use the command \begin{flushleft} sample text.\end{flushleft} for every chunk of text? Also, is there a keyboard shortcut to "Run" the document? It seems like you're not pressing the arrow button with your mouse cursor every time you preview the doc. Is there a way to quickly preview what I had done before to compare the before and after I pressed the "Run" button? An equivalent of Word document's "Ctrl+z" perhaps? Thank you!

Thank you so much. Question: TChain *ch1 = new TChain("tree"); In this line, we passed the name of the TTree that was used in the write(). What if we had different named trees in different files?

Thank you for tutorials. Do you know how to make sure all the elements of a 2D histogram is well within the canvas (last thing that you mentioned in the video)? I was trying to plot a simple 2D Gaussian histogram with this code, but whatever value I put to adjust the right margin, root do not show me all elements (it cuts off the z-axis title "Entries"). I tried adjusting the title size , title offset, but didn't work.

Thanks for your tutorial. Can I take a file from an example such as neuron to another example such as chem1 and insert this file to have the dimension of the target? Could you help me, please?

thank so much this was a lifesaver

thank you for the lessons. I have the following errors in the program, can you tell me how to fix them? Thank you in advance. PYTHIA Error in BeamRemnants::setKinematics: kinematics construction failed after retrying 10 times PYTHIA Error in BeamRemnants::setKinematics: no momentum left for beam remnants PYTHIA Warning in SimpleSpaceShower::branch: used up beam momentum; retrying parton level PYTHIA Error in Pythia::next: partonLevel failed; try again

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.

Hi! I have added both Optical interactions just as you did, but still I cannot see any phtons, so to speak cherenkov light.

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

As an atheist I shall join

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.
