Newcomers to Arts and Humanities

Hello Readers!

Finally, after such a long gap, I have found an insightful topic to share. Today's topic is about the class of people who feel bored, tired, and sick of the rat race of chasing after money, mindless scrolling, disturbed social relations, and a meaningless, stressful life. Many of us suffer from anxiety, and stress and seek out the best resort in watching films, listening to songs, and sharing funny short videos and reels with friends. Amidst this practice, there lies a wonderful factor of creativity. A person always finds some songs, films, and stories quite relatable because of the deep charm of creativity behind the content.

Now let me put a debatable topic here.

"People from non-arts backgrounds appreciate the creative and philosophical aspects of enjoyable content, feeling that, despite having all the luxuries and wealth, something meaningful is missing from their lives. Meanwhile, individuals in creative arts and philosophical fields tend to broaden their current knowledge and go beyond the available content."

There are two premises here.

1. People from the STEM field
2. People from creative arts, humanities, and philosophical branches.

There are two points of view as well.

1. People from the STEM field enjoy the depths of all arts and creative materials such as films, songs, and stories, and at one point in life, they think they could have pursued arts and humanities.

2. People from arts and humanities, and creative pursuits undergo a rigorous process of ego clashes with the truth and redefine their understanding while creating anything new and original. This philosophical churning in mind makes them more refined thinkers and clean creators. They think that the world has to see things from their own perspective and think about life with a completely different dimension.

Whoever wishes to make a career in arts and humanities must understand the following things.

1. It is not just a branch of academics but a life-defining pursuit. It is deeply connected with all other branches such as science, technology, engineering, and mathematics. Indeed there is a value of rankings and grades but this branch is more than just academic accolades.

2. The majority of people give very little value to philosophies and stories in their daily lives and they keep talking about money, percentages, and major statistics. If one wants to study arts and humanities with a deeper knowledge, one may go deeper into the nuances of human behavior, the inner areas of the human psyche, and thought processes.

3. This also leads a person to a spiritual dimension and makes him/her rethink all the behaviors and endeavors of human beings. The key questions such as what, why, who, how, when, and where will become the drivers of the human mind rather than having a mind full of numbers that keep thinking about money all day.

4. Those who are not in arts and humanities may think that the people within this field are "lucky" and enjoying all the "luxuries" of life; but here is a myth buster: the real learners, thinkers, and creators don't enjoy the materialistic aspect of life and never expect to live like that. They consume only what they need the most and do only what is the most necessary at the given time and in situations. The only thing they enjoy is the clarity of their wisdom and life.

5. To study arts and humanities, one must be aware of the deeds of past figures and have a sharp historical and political sense to study whatever is happening in today's time. Because students will always have to see things of today with the pastness of the past.

6. During the study the students may get frustrated and tired of the rigorous thought process and discussions he/she has to go through. But no need to worry, to create a new understanding one must have a breakthrough of their own ego and pre-established beliefs. Once the mind is free from all the past conditions, a great highway is there to study further.

7. There should be readiness to leave the ego aside and know something new and fresh. Because no creative field is free from biases and mental conditioning. There might be a few aspects that may affect you directly at the personal level but it is the demand of this discipline that people go through this process and ask questions at deeper levels.

These points will be fruitful to the students and aspirants who want to study arts, humanities, languages, literature, and philosophies. This would definitely establish new perspectives and understanding of the entire world.

Change is inevitable, so the mind, so the body, and so the life. Embrace with all your power and spirit.

Happy learning.
Thank You!

Atom vs Nucleus

The atom and the nucleus are two distinct components of matter, but they are related. Here's how they differ:

  1. Atom:

    • An atom is the smallest unit of matter that retains the chemical properties of an element.
    • It consists of a nucleus at its center and an electron cloud surrounding the nucleus.
    • The atom includes protons and neutrons in the nucleus, and electrons orbiting the nucleus.
    • Atoms are electrically neutral when the number of protons (positive charge) equals the number of electrons (negative charge).
  2. Nucleus:

    • The nucleus is the central, dense core of an atom.
    • It contains protons (positively charged particles) and neutrons (neutral particles).
    • The nucleus holds almost all of the atom's mass but occupies a tiny fraction of its volume.
    • The number of protons in the nucleus defines the element, while the number of neutrons can vary, leading to different isotopes.

In summary, the atom includes the nucleus and the surrounding electrons, whereas the nucleus is just the dense central part containing protons and neutrons.

What's Happening in the Parallel Universe?

The parallel universe has become the trendy word for Gen-Z, but the generation uses different allusions to justify that there is a parallel universe 'for real.' Well, this shocks a person who knows there are many but we humans would never afford to visit any of them! And who knows, there are no such facilities for computers, the internet, and a space to write !!!

Jokes apart, sustaining life on the Earth is a worrisome thought now. Increasing population, job scarcity, starvation, and other international issues are much higher and demand our direct attention rather than sitting in a cafe and talking about trivia, who's lost the money, who got more likes, and who's richer.

Those who know the value of education, and science, would agree with the idea that our education will be helpful to the whole society only when the smartest minds are engaged in real-life problem-solving. ADHD has more concerns with the youth of the world. Unemployability is another issue. Climate scientists predict that future generations will have fewer resources of common goods. Water scarcity is a burning challenge.

Here are some of the popular journals and websites that talk straight to the point.

Springer
nature
ScienceDirect
Sage Journals

So, overall it is a wake-up call for all. But we can't wake up ourselves until and unless we possess a sharp and strong philosophy that is "Vasudhaiva Kutumbakam". This would be stronger only if we see ourselves as a small atom of the universe, and not as the center of the world.

Quantum Physics: Etymology, Definition and Examples

Etymology of Quantum Physics

  • Quantum: Derived from the Latin word quantus, meaning "how much" or "amount." It refers to the smallest possible discrete unit of any physical property.
  • Physics: From the Greek physis, meaning "nature." It is the study of the fundamental laws governing the natural world.

Together, quantum physics literally means "the study of the smallest quantities in nature."


Definition of Quantum Physics

Quantum physics (or quantum mechanics) is a branch of physics that deals with the behavior of particles on an atomic and subatomic scale. It describes the peculiar rules that govern the smallest units of matter and energy, such as electrons, photons, and other fundamental particles.

Unlike classical physics, which works well for large objects (like planets or cars), quantum physics operates in a realm where particles can behave in ways that seem counterintuitive, like existing in two places at once or changing their state when observed.


Key Concepts in Quantum Physics

  1. Quantum: The smallest indivisible unit of a property, like energy. For example, light is made of particles called photons, which are quanta of light.

  2. Wave-Particle Duality: Particles like electrons and photons exhibit both particle-like and wave-like properties depending on how we observe them.

    • Example: Light sometimes behaves like a wave (like ripples on a pond), and at other times, it behaves like a stream of particles (photons).
  3. Superposition: A particle can exist in multiple states or positions at the same time until it is measured.

    • Example: An electron can be in several different locations around an atom, but when you observe it, it "chooses" a single position.
  4. Entanglement: When two particles become entangled, their states are linked no matter how far apart they are. Changing the state of one instantly affects the other.

    • Example: If two electrons become entangled, altering the spin of one will instantaneously change the spin of the other, even if they are light-years apart.
  5. Uncertainty Principle: Introduced by Werner Heisenberg, this principle states that certain pairs of properties (like position and momentum) cannot both be known exactly at the same time. The more precisely you know one, the less precisely you can know the other.

    • Example: If you know exactly where an electron is, you can't be sure about how fast it moves, and vice versa.

Simple Examples of Quantum Physics in Action

  1. Photoelectric Effect:

    • Explanation: When light shines on certain materials, it can eject electrons from the surface. Albert Einstein explained this using quantum physics, showing that light comes in discrete packets called photons.
    • Real-Life Example: Solar panels work based on the photoelectric effect. Photons from sunlight hit the surface, eject electrons, and generate electricity.
  2. Schrödinger’s Cat (Thought Experiment):

    • Explanation: Schrödinger imagined a cat inside a box with a radioactive atom that could either decay or not decay, triggering the release of poison. According to quantum physics, until you open the box and check, the cat is both alive and dead (a superposition).
    • Purpose: This paradox illustrates how quantum particles exist in multiple states until observed.
  3. Double-Slit Experiment:

    • Explanation: When light or electrons are shot through two slits onto a screen, they create an interference pattern like waves. But when observed, they act like particles, passing through one slit or the other.
    • Real-Life Example: This experiment reveals wave-particle duality and shows how observing a system can alter its behavior.

Summary of Quantum Physics Principles

  1. Discreteness: Energy and matter are quantized, coming in tiny, indivisible units.
  2. Wave-Particle Duality: Particles can behave like waves, and waves can behave like particles.
  3. Superposition: Particles exist in all possible states until they are measured.
  4. Entanglement: Two linked particles can instantly influence each other across any distance.
  5. Uncertainty: There's a fundamental limit to how precisely we can know certain properties of particles at the same time.

Quantum physics challenges our classical understanding of reality but forms the foundation for much of modern technology, like semiconductors, lasers, and quantum computers.

Shitala Saatam - Religion vs Science

Welcome Readers!

Festivals play vital role in human's life. In our routine and monotonous life, festivals fill the empty gap of happiness, jubilation, and encouragement. Indian festivals are firmly connected with religion, mythology and legend stories. There are many festivals which are not directly connected with the original myth or scriptures, but still they have their space. Naag Pacham, Chhath, and Shitala Satam are such festivals. If a rational and critical thinker visits India and observes some rituals of worshiping of disease like smallpox, what impression he will take about India? Natural elements like vegetation, water, fire, air, all the seasons like, autumn, spring are majorly seen through the eye of religious thoughts. Fear is the deeply rooted feeling in the conscience of human being. Whichever thing he can't control, he submits and surrenders himself and bows in front of it. Whether it be a natural calamity or deadly disease like smallpox which we call it Shitala (શીતળા).

Here's one link of blog about this topic, posted by Dr. Dilip Barad.

What's in the air ?


Shitala (smallpox) was once a deadly and incurable disease, which is now fully curbed. One pioneered the idea of vaccination in the medical field, none other than Edward Jenner was the first to find the cure of smallpox from cowpox. Iron cuts iron. The disease of cowpox became the vaccine of smallpox. Jenner experimented this for the first time in 1796. At that time, Indians were worshiping this deadly disease as Mataji (Goddess), because it was incurable. There is also one rational idea that eating cold food like curd, buttermilk, hotchpotch, cold roti, thepla, helps with deficiency of vitamin B12. But of course for Indians it was not followed with intention to cure the deficiency but to be saved from the wrath of Shitala Maa.

Here's one link of article, which will break many misconceptions and will demolish the 'excessive pride', which Indians take about curbing the disease on first hand. Click here to read the article. When we see falsified manifestation of any visible object and yet people, by becoming sheeple, blindly follow the lead, somewhere in the corner truth is being revealed in the form of articles and write-ups. Just a little ray of light, enlightens the dark corner and we find the truth that bring awareness.

Awareness is All


While India was busy in worshiping this Shitala Mataji, people in Britain were afraid of taking the cowpox vaccine, which was the cure to smallpox. This image is mocking at the fear of people, who are imagining that they will grow cow heads on their bodies. At least this fear of people was good rather than worshiping the disease as Goddess. Even after having the fear, they are sitting there to take the vaccine.


If people will not be aware of the current diseases, then how will rumors be stopped ? In the 21st century people should think every aspect with multidimensional views. In this image we can see how Edward Jenner is doing good karma by advising a farmer to vaccinate his family. Unless we start thinking, re-looking on issues, our minds will always be captured by such fake mentalities and will never be free from 'Conditioning'. Let's be hopeful that India will be fully free from superstitions and let's spread this thought to people. Let's be aware together.
