A Nineteen‑Year Echo: Returning to a Technology That Refuses to Stand Still

When I logged back into this old blog after so many years away, I expected dust, silence, and maybe a few broken links. Instead, I found something unexpected: people are still reading a piece I wrote nineteen years ago, an article about optical cloaking, back when the idea felt like a fragile spark from the edge of science fiction. Curiosity got the better of me. What happened to that technology I once wrote about with such excitement? Back then, cloaking was mostly theoretical, an elegant mathematical possibility built on metamaterials and transformation optics. The physics was promising, but the real world had not yet caught up. So I went searching. To my surprise, the field has not only survived, it has matured. Researchers have pushed optical cloaking far beyond the early conceptual stage. Over the last two decades, it has grown into a serious scientific discipline, with real prototypes and expanding applications. A 2021 review describes how invisibility research has “blossomed...

In the Long Echo of My First Blog

I haven’t written anything on this blog for several years. That doesn’t mean I stopped writing, far from it. I’ve always loved writing. I simply shifted my words to Facebook for a while. But this space… this is the blog I started many years ago. I was one of the early bloggers, writing almost from the moment the internet found its way into everyday life. Back then, I published in various online magazines and newspapers during those pioneering days of the web. The world has changed so much in the years since. The internet and its surrounding technologies have seeped into nearly every corner of human life. Many of these changes have been wonderfully positive. Learning has become easier than ever. Watching a good movie or TV show takes only a few taps, and the choices feel endless. Gaming has evolved into entirely new dimensions. I can carry an entire library with me, on a dedicated e‑reader or simply on my phone, with every device syncing effortlessly. Even when I’m driving through moun...

Writing

 I haven't written any blog post a long time. This is unusual for me. Writing is my passion from my childhood. I don't know how I stopped writing altogether. Hoping I can return to this love of my life.  Life has become very busy for me in recent years. Being a father of a son, working full time, family and all the daily humdrums that come with living a life, perhaps played a role in my long time absence from writing.  I am not sure how large the readership of my blog posts. Hoping whoever you are, where ever you are, you all are safe and having a good life.  Will write more soon.

Stop the War

1. War is always painful. It brings destructions, devastations and deaths. Peoples' lives and livelihoods are uprooted. Schools, hospitals, shopping malls, nursing homes, apartments, community centers are bombed. Bullet ridden bodies of men, women and children lie on the roads and the side ditches have congealed blood filled rocky ice like compassionless stones.  Human history is full of wars, invasions, occupations of foreign lands and genocides. From the time of antiquity, the invaders and the aggressors try to justify their bloody actions. They cite past injustice fallen on a segment of a population as the precursor. They cite security risk posed by the invaded nation as the root cause of their occupation.  Russian invasion of Ukraine falls into the same pattern.  Was there injustice in breakaway eastern Ukraine from 2014 or before? Most possibly there was.  Did the injustice in eastern Ukraine got world's enough attention? Most probably not.  But does it giv...

The Body: A Guide for Occupants by Bill Bryson - a Review

This is the second book of Bill Bryson I have read, and like the first one, A Short History of Nearly Everything that I had read  more than a decade ago, The Body: A Guide to Occupants is a well researched and thoughtful book that has good information of human body presented in humor mixed and eloquent format that I found to be highly readable like his other book I had read.  Some of these concepts that the writer presented was not new to me, as I had studied some of these concepts in various biological science courses I had taken in high school, colleges and universities, but unlike the heavy tomes text books that I had to plough through in my student life, as I read Bill Bryson's book I found it more amusing and some of the tidbits about various scientists, accidental discoveries, and treacheries of some scientists not giving due credit of the original discoverers or inventors of their hard work shed light on the dynamics of world of science that mimic the larger outside wor...

Pachinko by Min Jin Lee - a Brief Review

Min Jin Lee’s Pachinko is memorable and full of heart and life’s struggles, ups and downs, challenges, survivals and kindness portrayed in lives of many characters of this unforgettable novel. The author shined a light over Korean people who lived in Japan for many generations, their longing for their unreachable motherland and being forever “outsiders” in Japan. From the start to finish the author told a long but compulsively readable story, and described the harsh life of poor Koreans living in Japan. It also showed how hard work to provide for their family pushed them to work harder, and some of them were successful climbing out of the deep pit of poverty, and many were not so lucky. Pachinko is a well researched novel and is a pleasure to read.

How Does Bigotry Enter into Mind?

1.   How does bigotry enter into mind?  I thought about this question for sometime now. A child is born with pure heart, no shred of bigoted ideas or thoughts can be present in his or her pristine mind. When I cradled my son for the first time, he was so tiny. The nurse wrapped him up in a small blanket and first she took him to my wife, the mother who gave birth after an agonizing delivery process that lasted more than 16 hours. Then I hold him in that wrapped up blanket. He could not open his eyes fully then, slept the entire time I hold him for about an hour before we left the delivery room and went to the recovery room.  Children learns from the parents. It took my son about an year to say a coherent word though he had started blabbering some words way early than that, maybe in his 3rd or 4th month he started saying meaningless words as part of his learning.  If angels are real then children are angelic. They come to this world with open mind. They look at t...

Hoodwinked

 The meaning of hoodwink I learnt not many years ago. I don't even remember from where I first heard of this word. Its dictionary meaning is: "deceive or trick someone".  Growing up in Bangladesh I am very much familiar how the corrupted politicians hoodwink as many people as they can. Democracy was not easy to achieve in Bangladesh. After its bloodshed filled independence war when millions died and millions more injured and after only a few years of the governance of the first elected government, more bloodshed came, and multiple governments came and gone by several coup-d'états.  In my childhood we had only one television station and one main radio station in Dhaka. Government ran both of these. So, whoever was the government in particular time utilized these mediums as effectively as they could to propagate their political agendas, to hold onto power.  Even, the newspapers and cinemas had to go through strict censorship.  Still, each military based government...

Hold Fast to Dreams

 I love to read often the following poetry snippet of Langston Hughes':  "Hold fast to dreams  For if dreams die Life is a broken-winged bird That cannot fly. Hold fast to dreams For when dreams go Life is a barren field Frozen with snow."  Only 8 lines and 33 words, and the poet wrote the necessary words many years ago that are needed in this time of growing sadness from a wild fire like spreading pandemic and political and economic instability. "Hold fast to dreams", he says again, "Hold fast to dreams", that is the key to hopefulness and living in this beautiful world for however brief our existence may be. Hold fast to dreams.
