A user seeks assistance in identifying a particle observed in a cloud chamber developed with their son, who is interested in quantum physics. The discussion highlights that the observed particles are likely charged, specifically beta or alpha particles, with beta particles producing longer, thinner tracks. Additionally, muons are mentioned as common observations in cloud chambers, with an average flux of about one muon per square centimeter per minute at sea level. The community offers insights into particle identification based on track characteristics. This exchange emphasizes the educational value of hands-on experiments in understanding particle physics.
My question is about the following graph:
I keep on reading that fusing atoms up until Fe-56 doesn’t cost energy and only releases binding energy. However, I understood that fusing atoms also require energy to overcome the positive charges of the protons. Where does that energy go after fusion? Does it go into the mass of the newly fused atom, escape as heat or is the released binding energy shown in the graph actually the net energy after subtracting the required fusion energy?

Hello everyone,
I am trying to calculate the energy loss and straggling of alpha particles with same energy, I used LISE++ to obtain the energy loss in every layer of the materials using Spectrometer Design of LISE++, but I can only calculate the energy-loss straggling layer by layer. Does anyone know the way to obtain the energy-loss straggling caused by every layer?
Any help would be appreciated.

Since E = mc^2, how can photons be massless? If a photon has no mass, then, according to Einstein's formula, its energy is given by E = 0 x c^2, which is 0. Yet, photons do have energy. This seems to be a complete contradiction. Please explain! Thank you.
