    I need advice on whether to drop physics or software design and development.

    You don't need to worry about your subjects being helpful in your future degree/course (unless it is a prerequisite) - but considering the information you've provided it seems that you are more interested in physics so perhaps you should consider dropping software in that case

    Mass defect of nuclear fission/fusion

    I am a bit confused about the mass defect occurring from nuclear fission/fusion reactions. Online sources + textbooks say that the products of a nuclear fusion reaction will have less mass than the reactants, and will release energy in relation to E=mc^2. But in my matrix book, they are saying...

    Question about Special Relativity

    How do relative velocities work near the speed of light. Say u r shooting a bullet that goes at 0.8c from a spaceship that goes at 0.8c, what is the velocity of the bullet relative to an observer on the ground? I know that this equation gives the answer, but could someone pls show how to derive...

    Physics MOD 7 Confusion - any help asap is appreciated

    hello, so my question is related to the measurement of the speed of light. 1. Maxwell predicted existence of em waves in 1864. He then went on to calculate the theoretical speed of an em wave. he then said that light is also an em wave. 2. then in 1900's hertz proved that em waves existed by...
