The Scientific Method Helped Us Move Beyond Mythological Thinking To Rely On Evidence And Logic For Answers
For centuries, human beings have been grappling with questions that have no easy answer.
We have always asked why we are here, if we are alone in the universe, and if there is a creator.
In order to tackle these complex issues, humans looked for an explanation in gods and mythology; whenever a natural disaster or drought occurred it was assumed to be them punishing us for our negligence.
But then came along ancient Greek philosophers who wanted better answers so they started questioning the god explanations.
We owe many of these thinkers the credit for the advancements which transitioned us from mythological to scientific thinking; Aristotle, Archimedes, Thales and Galileo being just some of those whose impact cannot be underestimated.
These pioneers’ hard work paved the way for what became known as the scientific method – namely a system that proved successful at delving into life’s bigger questions by experimentally testing hypotheses while observing and measuring results.
Isaac Newton furthered this revolutionary concept when he formulized laws of gravity and motion using his findings through this system leading us to understand more how our environment works like never before.
This eventually enabled scientists to explain almost every physical phenomenon according to science in modern times, a line of thinking known as scientific determinism which holds true even today in regards to human decisions as well!
The quest to understand our world took us from trying to please mythical gods to utilizing sophisticated scientific techniques; from turning blind faith into strict evidence-based inquiry – all thanks to centuries of intellectual advancements!
Is Free Will Real Or An Illusion? The Debate Between Scientific Determinism And Human Nature
Scientists have long debated whether humans possess free will, or if we are subject to scientific determinism.
This has been an area of much contention and has left many people contemplating the answers to seemingly unanswerable questions.
The philosopher René Descartes rejected the idea that human beings were merely robots adhering to pre-programmed instructions, and instead proposed that free will comes from our soul – located in the pineal gland in the center of our brain.
However, this theory raises a lot of questions: do other animals have free will? Is it limited to multi-cellular organisms or can bacteria possess it too? Where is the line between things subject to scientific law and those with seemingly magical capabilities?
Recent breakthroughs in neuroscience provide some insight into how physical and chemical laws drive the thoughts and decisions that we make.
We now know which areas of the brain should be stimulated in order to produce certain behaviors like talking or moving parts of our body.
So, any choices made by us can be attributed to biological mechanics, just like other organisms around us.
We All Experience Reality Differently, Even Fish In A Fishbowl
The idea that our reality is not absolute, but instead dependent on the individual’s perception, is the central argument of The Grand Design by Stephen Hawking and Leonard Mlodinow.
They posit that there is no “reality” independent from the observer – what you see as real is actually a mental picture your brain produces from the information your senses send.
This notion can be illustrated by examining how a goldfish perceives its environment: if it lives in a fishbowl in your living room, does it experience a “distorted” reality? The city council of Monza, Italy thought so when they outlawed curved fishbowls in 2004.
However, this line of thinking presumes that there is one definitively correct version of reality to behold.
In truth, each living organism creates their own scientific laws based on their own observations.
For example, even within the sphere of their curved fishbowl world, a goldfish may develop accurate rules governing its environment using its senses just like us humans do with ours!
Ultimately then, every organism has an equal capacity for understanding the “reality” within the limited scope of their own perceptions; whether or not these realities conform to wider accepted laws is irrelevant.
The Four Criteria For A Good Scientific Theory: Elegance, Limited Adjustable Factors, Explanation Of Observation, And Contributions To Future Predictions
In order for a model of reality to be considered a good one, it must adhere to four criteria.
Firstly, it needs to be elegant – Einstein famously said that “everything should be made as simple as possible, but not simpler.” Secondly, it must not be dependent on too many adjustable or random factors.
Thirdly, any good model has to explain all existing observations and finally, it must contribute to future predictions.
The Grand Design makes the case that an elegant and consistent model should fit reality and have predictions based on what is observed.
It’s only when these criteria are met that one can safely say the model is a good representation of reality.
Additionally, according to The Grand Design, once these criteria are met, the best models become laws of nature themselves – this is why prestigious scientists strive for elegance in their theories.
The Uncertainty Of The Subatomic World: How Observations Disrupt The Quantum Realm
At the subatomic level, nature is completely different from what we observe with the naked eye.
Quantum theory reveals the secrets of this hidden world and provides us with a fundamentally different view of reality.
Take for example, Werner Heisenberg’s uncertainty principle.
According to him, it’s impossible to accurately measure both the position and momentum of a particle at the same time.
So all we can do is calculate probabilities in terms of where a particle is likely to be.
Furthermore, quantum mechanics tells us that simply observing an object has an effect on it.
Shine light on something big like an apple and nothing happens, but send photons at particles too small to see and you’ve drastically altered their movement and direction.
This means that conducting experiments on this level is incredibly challenging yet paramount in understanding nature at its most basic level.
In conclusion, quantum theory provides us with a totally different conception of the world as it describes nature at its most basic scale – and it’s up to researchers to uncover just how far this knowledge can take us.
Einstein Revolutionizes Physics With Theories Of Special And General Relativity: Space-Time Warp, Slowed Perception Of Time, And The Force Of Gravity Explained
Albert Einstein revolutionized the way we understand time and space.
In his Theory of Special Relativity, he proved that the notion of time is relative and not absolute.
To illustrate this point, imagine being in an airplane flying close to the speed of light.
From your perspective, a beam of light will remain travelling straight up and down while it passes you by.
But from an observer’s perspective on the ground, they would see a different path for the light – moving at an angle with each bounce.
This phenomenon can be explained since light always travels at 186000 miles per second regardless of how fast you move – meaning if your perception of distance changes, then so does your perception of time.
Einstein’s Theory of General Relativity also gave us a much greater understanding of gravity – something which previously left scientists scratching their heads.
He envisioned our universe made up of both space and time, referred to as “space-time”.
He compared it to a warped billiard table where objects are pulled towards some gravitational center and orbit around it.
This explains why planets in our solar system are able to orbit around astrophysical bodies such as stars.
Thanks to Albert Einstein, we now have a clear understanding on how time relates to space, and how two seemingly separate concepts are well intertwined together.
The Search For A Grand Unified Theory: How The M-Theory May Be The Key To Understanding Our Universe And Beyond
For centuries, physicists have been in search of a Grand Unified Theory (GUT) that will unite together the four fundamental forces of nature – weak nuclear force, strong nuclear force, electromagnetism, and gravity.
But after decades of searching and experimenting, all attempts at formulating a GUT so far have proved to be unsuccessful.
However, there is still hope in the form of M-Theory.
Unlike traditional attempts of a unifying theory which focuses on just one single set of equations – M-Theory is more like an atlas with each page containing details about local areas.
But most importantly this theory brings the possibility of multiple universes; which may just explain why ours is fit for life.
Although many scientists argue that we are far from knowing it all – this could very well be our best chance yet at finding a unified theory of everything.
It Takes More Than Just Luck To Create A Habitable Planet: Examining The Creation Of Our Universe
The universe is expanding and modern science has the tools to explain why.
As astronomers have discovered, nearly all galaxies are moving away from us and at an increasing rate.
By rewinding the expansion of the universe back to when it was still tightly concentrated into a small area of incredible density, scientists now believe that this moment in time marks just before the Big Bang.
The resulting explosion brought us to where we are today, and we are incredibly lucky that Earth is located within what’s known as the habitable zone.
Located in an area that is just the right distance from the sun, away from destructive meteorites, and not too hot nor too cold – water which makes up much of our planet’s surface is in a perfect state for sustaining life on Earth.
It’s likely a sheer matter of luck that we find ourselves here in this part of space and not somewhere else; But at least we can marvel at both our location and how far we’ve come!
The Grand Design by Stephen Hawking and Leonard Mlodnik is all about shattering preconceived notions of how the universe works and uncovering the physical laws that govern it.
Through this book, the authors believe that humans have finally been able to explain physical occurrences without attributing them to gods or other supernatural beings.
The key message in this book is clear: the universe can be understood through physical laws, and these laws can be discovered, thanks to the advancement of science.
The scientific method has given us access to a new way of looking at and understanding physical laws, enabling us to shoot for a deeper, more accurate understanding of how things work in nature.
This book serves as a powerful reminder that people should never stop striving for greater knowledge and insight into our universe.
