Since someone requested for me to 'share' about quantum mechanics(QM) although I don't know what he really meant by 'share',I'll give u guys an intro to QM. It will NOT be 100% correct so pls don rely on it. Go search google for more info k??? This is my view on QM.


Ok. What is quantum mechanics(QM) in the first place?? QM is the study of the behaviour and nature of sub-atomic particles at atomic/quantum level. At sub-atomic level, these retarded tiny particles behave way diferrently from how we see normal objects behave in our daily life. I'll come to its 'weirdness' later. The fathers of QM were Max Planck and Albert Eisntein and many other physicists like Neils Bohr.

QM came to light when physicists were trying to solve the Black Body radiation problem.(BBR) A black body absorbs light energy and amazingly, it 'glows' to radiate some of the energy it has absorbed. Max Planck hypothesized that the energy released by the black body are released in 'packets' and at a certain frequency. This is given by the equation E=hv. Where E is energy, v is frequency and h is planck's constant.

Einstein later discovered the photo-electric effect by which when light is shown onto a charged surface(eg. negatively charged), the surface will eject the negatively charged particle(eg. electron). As if light are made of particles and these particles of light, when shown, hits the electrons and sends then flying. Einstein proclaimed that light was made of particles called 'photons'. And this statement was once said by Issac Newton which said light was made of particles he called 'corpuscles of light'. Lol. Looks like Einstein and Newton were rivals from different eras.

Whats the first thing u learn now? Light is made of particles. BUT. Light is also a wave - electromagnetic wave remember?? How can something be a wave and a particle at the same time?? Crazy right? Think. Imagine a ripple in the pond. moving north. Ok. Imagine a ball moving towards the north. They are WAy different. Waves can spread and but particles dont. Particles are like dots. Or small balls. lol. yea.

NOW. We move to another chapter in QM. Wave particle duality. Meaning that a particle or any object(including u and me), half of the time we behave as particles and half of the time we behave as waves. Thats what they say in QM. Well, its still unexplained why partcles can behave as waves. This is where QM becomes very weird. This is a video to show u what I mean. Btw. electrons are waves not particles=)





Ya. And when they place that observer, the electrons behave as particles again. Crazy right? Its really as if they knew what we were doing. They wanted to stop us from finding out their secret.


Now we move on to the Uncertainty Principle. This states that the position or other conjugate variables of a particle CANNOT be known with 100% accuracy. This means that we are 'uncertain' of the position of any particle. And we will never be sure of where it exactly is in space.
Ok this quote is from wiki:'In quantum mechanics, the particle is described by a wave. The position is where the wave is concentrated and the momentum, a measure of the velocity, is the wavelength. The position is uncertain to the degree that the wave is spread out, and the momentum is uncertain to the degree that the wavelength is ill-defined.' get the idea?


Physicists also discovered that Protons and Neutrons are made up of even smaller particles called quarks. I'll name the six types that i know of Up,down,charm,strange,top,bottom. And what are these quarks made up of??? A theory says they are made of "strings".(go research on string theory if u wanna know more).


Ok to sum it all up, quantum mechanics is a field of study that allows us to know about how the atomic world works. If u wanna know everything about it - go take physics course in university(I wanna go for it)=).
