I Introduction to Quantum Mechanics

[Bilal Rajab Abbasi]

Hi! I am Bilal Rajab.
I have a question regarding Quantum Physics.
From where can we learn about Quantum Physics and what is its relation to Classical Physics?
Why is there not one single Physics...?
Thanks

Here in the US, at various points along the many thousand of miles of US highway systems, there are "weighing stations" that weigh commercial trailer trucks, to make sure they are not overweight and become a safety hazard. Now, do you think these weighing machines can also weigh chemicals in the sub milligrams scale with the needed accuracy? If you drop a grain of sand on such a scale, do you think it will even make a difference on its reading? You have to switch to a more accurate weighing scale, which will have greater accuracy, but you sacrifice the range of weights that you can now measure. A chemical balance is certainly not the equipment you would use to weight a truck, or even a potato.

In other words, you use the proper instrument to do what you want.

There actually is just ONE single physics. But it has many different loose sub-areas. It also means that they are all inter-related and connected. There are forms and mathematics that look similar or even identical in different areas of physics. This is why the study of magnetism and superconducitivity in condensed matter physics gave birth to the Higgs mechanism in elementary particle physics.

This is why students usually get an undergraduate degree in "Physics", not in Classical Physics, not in Quantum Physics, not in Electromagnetism, etc... A physicist is expected to know the basic knowledge of all the fundamental areas of physics, not just one.
