Yes. Mass and energy are related by E=mc^2. When a nucleus loses energy, its mass decreases. The change in nuclear mass during a gamma decay is small, but nonzero. And E=mc^2 is actually a simplification of a larger equation which includes a momentum term. But that term is only significant for particles moving near or at the speed of light. A gamma photon for example-it has no mass but it has momentum and energy, and moves at the speed of light. So the momentum term is important for calculating its energy. But for a nucleus at rest, the equation simplifies to E=mc^2.
This makes me ponder about how this surgery is performed...In this surgery, the positions of the tumor, relative to the skull and laser apparatus are essential, and the skull position must be fixed and anchored in a known location for the initial setup. Then, I would assume the head is mapped in real time, and tumor position tracked for coordinate conveyances to servo motors on each laser that respond to even the slightest movement of a patient, so an accurate position in 3d is constantly mapped. Something like that I would think, just for starters
So when the elections in the circuit pass this np junction as they pass that junction that's when the photon is created? Are these photons a gamma radiation, but just not of a non ionizing quality
This is actually really helpful because I missed a week of school when we were talking about nuclear decay and my Chemistry final is tomorrow.
10:52 YO ! HUMANS ARE CRAAZZYY 😭😭
the application part is just!!!! i get all excited when i see the application part, your are literally the best sir!!!!
Your explanation is absolutely incredible! Thanks!
gracias por existir khan academy
Amen
That is an amazing part! but How it can't damage other cells that are in its way like skin cells and skull and others?
Low intensity beam so few photons…. That is why we need to use a lot of them concentrated in the tumour region in order to have an effect
Love you mahesh sir
An excellent tutorial; a straight forward explaination of nuclear physics
This guy is amazing
Thank you, Mahesh. Your passion is awesome! 👏
Mahesh is absolutely amazing in his explanations.
Thank you so much your teaching is amazing🙏🙏
In beta minus radiation how do the down quarks actually transform to up quarks to make a proton from neutron?
So on the emission of the gamma ray does the nucleus lose mass?

Fantastic explanation

Thank you very helpful
That was great. Thanks. Now I just have to find a way to use gamma radiation to tap into the hidden strengths that all humans have
thanks
Loving your videos!

U r the real 🐐🔥 the 2nd comment pls pin🙏
Perfecto
Ok can we excite a single proton
what app is this writing on?
Sketchbook
❤❤❤❤
Were talking about orbital energy......then all of a sudden energy of nucleotides!!!!!!!.....ok....
Your videos are always interesting 🙏🙏
