AI Thread Summary
The discussion revolves around calculating the energy released from a mass defect of 1 atomic mass unit (u) using both kilograms and MeV/c². A user expresses confusion over discrepancies in their calculations using Einstein's equation E=mc². Other participants emphasize the need for the user to provide their calculations to identify errors. The user requests a demonstration of the energy calculation using kilograms first, then MeV/c², to clarify their understanding. Ultimately, the issue is resolved, indicating that the user found the needed information.

So 1u = 931.5Mev/c2 = 1.67 10_27 kg . the thing is when i calculate E=mC2 with both units the calculations don't match . i can't understand why .

We can't help you to find your error, if you don't show your calculations.

Thank you for the attention sir . unfortunately i am using my phone to type so i cannot write all the calculation . can you please write the Energy released out of a mass defect of 1u by using Kg first then MeV /C2 as the unit of mass ? That can solve my problem
 
The problem is solved . thank you

Please note that this is usually not an acceptable excuse to not lay out the full and complete post. It is why the PF Rules also prohibit text-speak.

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
