ok sorry :/

Thank you for the responses everyone. I think I understand what you are trying to say. If I could ask one follow up question to ensure that my understanding is sound. My understanding is that photons have energy and momentum, but never mass. Is this correct?

I read somewhere else on this forum that photons have zero invariant mass, only relativistic mass. Here is my problem, Einstein's equation for relativistic mass says that is invariant mass is zero then so will relativistic mass at all velocities. If a photon does have relativistic mass, then...

Thanks for the replies :D You've given me some good food for thought. I probably will keep the option of pursuing a career in mathematics open.

Thanks for the advice. I actually sat another Exam today. The last question required us to optimize the volume of a square based rectangular prism of given surface area. I only after i came home did i realize that when I re-wrote an equation a few lines down( Trying to knock up communication and...

Hello, I'm 16, live in Australia and am senior in high school. I do the highest levels of Mathematics which i can at school, and thoroughly enjoy them! I enjoy them so much infact, that i was considering math as a career. Here's my dilemma, after observing my marks i noted that i am hovering...

I do not study biology, i enjoy physics a lot more, but recently while i was thinking about our origins a question aroused my interest. As i said i do not study biology, and i do not doubt evolution(this is asked out of honest curiosity). From my understanding all life started as a form of...

No that's alright, thanks for the response it answer my question well.

Thanks guy's that cleared things up, however if two people naturally had an immunity to a certain strain of a virus it would then be reasonable to assume that the child is likely to have that same immunity right?

Hello, I am new to this forum and signed up to ask this specific question. From what i understand of evolution(which i am not trying to discredited here btw :cool: ) mutations are caused by either chance or adaption which then through natural selection favorable mutations are basically breed...
