Physics Spl

There are good opportunities in this field. But it will only be possible to grab opportunities when you also do MCA after BCA. Alone BCA will not work so much for you.
Therefore, try to do MCA along with BCA.
All the best.!!!

In 2012, scientists confirmed the detection of the long-sought Higgs boson, also known by its nickname the " God particle ," at the Large Hadron Collider (LHC), the most powerful
particle accelerator on the planet. This particle helps give mass to all elementary particles that have mass, such as electrons and protons.(GOOGLE)

Search on google in a good physics website
