๐Ÿ’น (English) Fun Science Reading

Review of *Quantum Studies with Kim Sang-Wook*

Image

๐Ÿ“– Title: Quantum Studies with Kim Sang-Wook
โœ๏ธ Author: Professor Kim Sang-Wook
๐ŸŽฏ Recommended for: Anyone curious about quantum mechanics in a fun, accessible way
๐ŸŒŸ One-line Impression: The end of rational science isโ€ฆ a dice game!?


๐Ÿ“˜ Book Review: Quantum Mechanics, the Key to Unlocking the Secrets of the Universe

Iโ€™ve always been fascinated by pure sciences like philosophy, physics, and mathematics.
Back in high school, I learned that atoms are made of protons and neutronsโ€”basic stuff.
But once it got into things like bosons, Higgs particles, and spin? I read about them but instantly forgot everything.

So when I picked up this book, I honestly feared it would be another case of reviewing things I already didnโ€™t understandโ€ฆ
But to my surprise, it was incredibly fun to read.


๐Ÿง  Quantum Mechanics as a Story

This book was the perfect introductory level for someone like me.
What I loved most was how it approached quantum mechanics through people and events, not abstract concepts.
It felt like reading a documentary on the history of science. Thanks to this structure, I could visualize the trajectoryโ€”
Why a theory emerged, what it challenged, how it was accepted. That historical storytelling made everything clearer.


๐Ÿ’ป Quantum Computersโ€ฆ Still a Mystery

Of course, some parts were still tough.
Especially the section on quantum computingโ€”I read it all, but trying to recall it later left me going, โ€œWait, did I actually get that?โ€
Terms like quantum entanglement, qubits, and the idea that itโ€™s not just 0 or 1 but superpositions that enable faster calculationsโ€”I kinda get that.
But just up to there. Itโ€™s still pretty hard. ๐Ÿ˜ญ


๐Ÿงพ Most Memorable Concept: Information is Physical?

The idea that stuck with me the most was that โ€œinformation is a physical quantity.โ€
I didnโ€™t fully understand it, but hereโ€™s how I simplified it in my head:

โ€œKnowledge is powerโ€
And that โ€œpowerโ€ can literally function like F=maโ€”as actual physical force?

It was a refreshing and mind-blowing concept.
The idea that knowledge isnโ€™t just abstract, but something that literally moves the universeโ€”
It reminded me of The Secret, a book about the law of attraction I once read and found inspiring.


๐Ÿงช Double-Slit Experiment and the Simulation Hypothesis

As I read, one thought kept recurring:

โ€œWhat if this world is actually a simulation someone created?โ€

The double-slit experiment was pure mystery.
Just observing the experiment changes the outcome.
And whatโ€™s even crazier is that the point of observation can change the past outcome!

At that point, I really started wondering:
What if this whole world is a simulation just for me?
Everything I havenโ€™t observed might be in a superposition state, like Schrรถdingerโ€™s cat.


โ˜ฏ๏ธ The Paradoxical Takeaway

Quantum mechanics is full of precision, logic, and mathโ€”
And yet, after reading it, my conclusion wasโ€ฆ

โ€œI should live kindly.โ€

If observation changes reality and thoughts influence the world,
Then perhaps the most important thing is what I think, what mindset I hold.

Like a religion, like a philosophyโ€”or maybe like rules written into a cosmic simulationโ€”
I closed the book holding a kind of superstitious belief: donโ€™t think bad thoughts.


๐Ÿ’ฌ Final Thoughts

This book doesnโ€™t just explain physics.
It weaves together history, philosophy, and the human stories behind science,
Giving the reader a new lens on the universe itself.

Sure, I still donโ€™t understand everything.
But I feel like the world expanded a little bit after reading it.
And next time, Iโ€™d love to explore quantum information theory or simulation theory further.

This book is a true giftโ€”making โ€˜quantum mechanicsโ€™ a joyful and thought-provoking experience.
