This channel is about physics. It includes lectures and exercises related to physics, as well as programming tutorials for ROOT or Geant4.
Forces
In this video, I describe the properties and types of forces that we can observe in our daily life. After that, I explain how to add up and decompose forces using an example of an inclined plane. Especially for adding up two forces with the known angle alpha between them, the law of cosines is used. The decomposition is explained with an example of an object hanging on two ropes or cables.
🌟 Learn how to:
✔️ Describe the properties of force
✔️ Combine forces to one net force
✔️ Balance forces
✔️ Use the law of cosines
✔️ Decompose forces

UP, you went into great detail, may I ask what software you use for teaching
I am using xournalpp for the whiteboard and obs studio for recording. For xournalpp I did some customization for having a 16:9 board and shifted the toolbar to the left.
@@physics_matters thanks
Bash: $dumpfile: ambigouse redirect error, what do it mean.
👌🏻🍀
Hi. Maybe you help me through a simulation with software GATE (Geant 4 applications tomography emissions) specially when this simulation needs much recurses as memory and cores. For that I need that someone explain like I can simulate in parallezation in a cluster. I look forward your kindly answer
Sir, can weight of stone influences the sound?
No the speed of sound is always the same no matter how heavy the stone is. Maybe the frequency of wavelength changes but it will not influence our calculation
Thank you for such a nice work.
Maybe you can do a video how to create a custom particle
Please make video on neutron radiation shielding
Hello, have you ever created a histogram for multiple sensitive detectors after importing file formats such as obj, stl to Geant4 with the CadMesh library? Is it possible to create one? Or have you ever tried it ? Thanks in advance.
You can create one histogram for each detector and then later display them in one canvas. Or you can fill the same Histogram in multiple sensitive detectors. There are indeed many possibilities to achieve the same goal.
@physics_matters Thank you very much for your answer, I have previously created multiple histograms for multiple detectors, but the data appeared in a single histogram and the other histograms were empty, Do you know of any examples of this? Thanks again.
After installing the root when enter root in terminal then show me root commond not found. Whats the issue?
You have to source thisroot.sh
Very useful 🤝🏻
Perfect and practical as always...
Thank you very much for such useful videos, you are very helpful in studying this program, could you record a video with volume sources and not point sources, for example, photons are emitted by some pipe from the inner surface. It would be very curious how this can be implemented. Thank you in advance
Yea I can do that as well. The easiest possibility is to use a random generator that randomly creates particles along the surface
@@physics_matters I know about the G4RandomDirection function, which emits particles in all 4pi, but I do not understand how to do this so that particles do not come from one point but from the surface, your option is very strong and it was cool to use not 1 detector but several at once, for example, to calculate the dose from a pipe that lies on the surface of the earth.
YES! I have been waiting so patiently for literally YEARS for an update to these tutorials!
Very helpful! Thank you.
thank you for your tutorial, would you please how to install a windows version if any?
Thank you very much for sharing this Geant4 tutorial; it has been incredibly helpful for a beginner like me. Would it be possible to create a tutorial that includes defining radionuclides using data from NuDat (such as decay intensity, and so on)? Additionally, can you add another tutorial how can we incorporate 3D models with STL file extensions into the geometry? Thank you again for your support.
Specially gamma ray domain
Please continue this further. This will be helpful
Thanks for sharing your knowledge through these tutorials, I learned a lot🍀
Thank you for the video. Helped a lot
I love your content but you look like if Hitler finished art school :)
When I try to compile I get an error that fontawesome5.sty is missing
Thank you... For this video.... I am eagerly waiting for more.
Nice🍀
I've followed the tutorial with no problems up to when installing the program with the command "make install" which ran without any errors. Nevertheless, when I go back to open the software/geant4/geant4-v11.2.2-install directory I get a "no such file or directory" error. Any ideas to why? Thanks!!!
Exercises: 1. A ball is thrown horizontally from a height of 1.70 m with a speed of 5 m/s. a) What is the maximum distance that it can cover? b) What is the impact speed on the ground? c) Under which angle does it hit the ground?
Hi, thank you for all your work. I'm trying to set a lower limit to the step length ej: 1e-3mm. I have only found a way to set an upper limit. Do you know a way to achieve this. Thanks in advance!!
Thanks!
Thank you very much for your support. This will really help me to improve and maintain my effort in the future.
Hello, starting from 12:21 I got an error in my terminal
I recommend watching my new tutorials about geant4 11 and also join our discord server
Thanks a lot. The installation works very well also in the new Linux Mint 22 release
Thank you for your time and efforts. Whish you all the best
i'm try to execute with the ./sim and the terminal show me: ./sim: error while loading shared libraries: libG4graphics_reps.so: cannot open shared object file: No such file or directory
I recommend to join our discord server
thanks! can you demo how to use GPU with Geant4
🍀👌🏼
Is there a part of the tutorial on how we can feed GÉANT with specific Nuclear Data Libraries ?
I am unable to see geometry in geant4 there is a blank screen after running the executable file. I have check all X11,, Qt everything is perfect but geometry is not visualising
Please join our discord server and download the source code from GitHub for testing
Thank you so much! Looking forward to more :)
I appreciate the time and effort you put into creating these tutorials; they make learning so much easier🍀🙏🏼
Thank you for all Mustafa, I do my Master Thesis thanks to your videos.
welcome back 🎉🎉 keep up 🙏🙏🤗🤗
please record more geant4 with examples
Yes I am publishing every week one geant4 video. The next one will come tomorrow afternoon
Exercises: 1. A bullet is shot straight upward with a speed of 1,500 km/h. a) What is the maximum height that the bullet will reach? b) When does the bullet reach its maximum height? c) How long is the total time of flight?
Thank you
Such a useful tutorial!
Great to see you back!! At some point can you go over sensitive detectors, hits, and hit collections? In your previous playlist of videos from some time ago you did some work with sensitive detectors which was useful, but now need to extract information about where the radiation is going... Thank you!
Please do more! This is super useful!
Hi Mustafa.. thanks for your previous tutorials and for this also. I have a request, could you do a tutorial on how to make each and every sites of a detector as sensitive detector ( analoge could be LAT of fermi space mission) Thanks in advance
Dear Dr. Mustafa It would be benificial if you create different folder for Cherenkov Multithreading Scintillator TOF for different tutorial unlike your previous tutorials. In a single tutorial it become cumbersome to understading what's happening in the code. Thanks for the tutorials
Yes I am creating now tags for every version which means every tutorial can be checked out separately
Hi Mustafa.. your last tutorial was awesome. Help me alot.
