E=mc^2

AI Thread Summary

Einstein's equation E=mc² is fundamentally about the equivalence of mass and energy, where E represents energy in Joules, m is mass in kilograms, and c is the speed of light in meters per second squared. The original poster initially used grams for mass but was corrected to use kilograms, which is the standard SI unit. The discussion emphasizes the importance of using correct units in scientific equations. The clarification was appreciated, confirming the accuracy of the explanation. The conversation highlights the need for precision in scientific writing.

I am doing an article that includes a brief explanation of Einstein's basic equation, and want to check my work. As I understand it, the equation is e(energy in Joules)=m(in grams)×speed of light in meters/second squared(9×10 to the 16th). Is this reasonably correct? Thanks.

Almost. In SI units m is in kilograms.

Edit: V50 for the win!

Kilograms it is. Thanks to both for the double-check!

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

Thread 'Raman Spectroscopy help'

I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
