Introduction
There are many children who are born geniuses. You look at a child and think, this kid is going to be a future genius. But when they reach their teenage years, only 10% of them retain their genius-level capability. Moreover, when they reach adulthood, only 1% retain their genius status. So what happened to the rest of those intelligent kids? They became prey to the expectations of society.
They get used to hearing the word no so many times that they lose their ability to fly. Society preys on people, killing their dreams. Every time a kid tries to do something new, parents notice and wont allow it.
Its the same way when these kids grow up and try to do something new. Society, teachers, and all the naysayers get in the way and wont let them do it. This cycle continues and finally they become prey to societys expectations. Now they start doing what society wants them to do, which is to live a life of mediocrity.
They finally start getting scared of society and accept what life shoves at them, because in the end they still have to live in a society of so called civilized people, where all their family members and friends live.
But the fact is that to be what you want to be, youll have to overcome all of this resistance. In my culture, we have a saying: any time anyone wants to do something different for themselves, the first opposition they will have to face is from their family, the second from their friends and relatives, and the third from society.
One thing to notice is that everyone opposing them are their own people. Thats why it is very hard to overcome this opposition. The enemy without can do no harm if there is no enemy within.
It is easier to win a war with an external enemy, but it is almost impossible to win when the enemy is on the inside. When the enemy is from within, it becomes difficult and confusing to know whether we are going the right or wrong way.
But believe me, every single way that does not make you happy is the wrong way, and every single way that fills you with joy is the right way. When you remove the fear of all of those people and overcome it, you will begin your journey towards success.
Another thing is that most of the resistance we feel is not realbecause the twist is that its our mind playing this dirty game with us. Your mind is your biggest enemy. We all let these thoughts and feelings control us because we are scared of these emotions. We are scared that if we go against the rules of society, it will be impossible to live well.
To overcome this, we need to have the mindset that we dont belong to regular society. We must believe that we belong somewhere above the rest and we must get to that place. Stop adjusting yourself to fit societyothers may not be able to handle your greatness.
You are much greater than you think. You are much more powerful than you have ever been, and you have a much higher status than what you are offered now. You wont know it until you give up the label given to you by society and start your journey towards something greater. You must be willing to sacrifice what you are today to become what you will be in the future.
One of the questions many ask is how does someone gain knowledge about a field as complex as quantum physics? As an individual with a love of science and science fiction, I was compelled to dive into this unique area of study. What started as a hobby when I was kid, trying to figure out if time travel was truly possible, has grown into a lifelong pursuit to understand how all of these theories meld together.
While some are good at math, the various scientific theories of quantum physics took work to understand and appreciate. My interest and love of the field grew over time but was sparked to life when my first science teacher introduced me to Albert Einstein. For someone new to the field or wanting a better foundation in quantum physics, Albert Einstein is a great place to start.
I think I can say that no one fully understands quantum physics. The main reason for this difficulty is that the quantum world (limited to the infinitely small, but which can have repercussions on a larger scale) behaves very differently from the macroscopic environment to which we are accustomed. Some fundamental differences separate these two worlds. The following are a few examples.
Quantification : A certain number of observables (for example, the energy emitted by an atom during a transition between excited states) are quantified. That is to say that they can only take their value in set discreet results. Conversely, classical mechanics most often predict that these observables can take on any amount continuously.
Wave-particle duality : The notions of wave and particle, which are separate in classical mechanics, become two facets of the same phenomenon, described mathematically by wave function. In particular, experience proves that light can behave like particles (photons, highlighted by the photoelectric effect) or like a wave (radiation-producing interference). Depending on the experimental context, electrons and other particles can also behave in an undulatory manner.
In particular, it is impossible to obtain high precision in measuring the velocity of a particle without getting mediocre accuracy in its position and vice versa. This uncertainty is structural and does not depend on the care taken by the experimenter not to disturb the system. It constitutes a limit to the accuracy of any measuring instrument.
Observation influences the observed system : During the measurement of an observable, a quantum system sees its modified state. This phenomenon, called wave packet reduction, is inherent in the size and does not depend on the care taken by the experimenter not to disturb the system.
Non-locality or entanglement : Systems can be entangled so that interaction in one place in the system has immediate repercussions in other areas. This phenomenon contradicts the special relativity for which there is a speed limit for the propagation of all information, the speed of light; however, non-locality does not allow data to be transferred.
