Primarily, we have been taught that a star and a few planets with moons around it make up the Solar System.

But there is a nuance. These make up only the bright “suburbs” of the Solar System.

Why suburbs? Because the entire Solar System is so vast that we can barely conceive of it.

The Sun is indeed the center of this astronomically broad orbital system. With that in mind, we shall move along the radius.

The core idea we’ve learned is that there are eight planets, with Neptune as the last one. As a bonus, some people have heard about Pluto, which isn't considered a planet but a “dwarf planet.” Here, “dwarf planet” refers to an object that looks like a planet (though smaller), orbits the Sun, but does not clear its neighborhood.

In contrast to other planets, it appears to contain icy objects floating nearby (icy objects here implies frozen water, CO, NH₃, CO₂, etc.).

Well, what's beyond?

Beyond Pluto begins the Kuiper Belt. A belt of frozen icy bodies that is also a source of short-period comets. It exists as ancient debris from the Solar System’s formation. It starts at about 30 AU from the Sun, and it's amplitude is ~50-55 AU. [AU = Astronomical Unit; 1 AU = 150 million km.]

Moving forward, if we somehow reach the heliopause (the edge of the solar wind’s influence), we enter the interstellar region. The region Voyager 1 is currently traveling through. [“Interstellar” means “between the stars.”]

Amid the interstellar region, the most mysterious part is confined.

The "Oort Cloud".

It's the most vague region of the Solar System. Due to its ambiguity of data, it remains theoretical, although there is indirect evidence supporting its existence.

However, for the sake of discussion, let's assume it's real.

Theoretically, this vast spherical region’s inner part (inner Oort) starts at ~2,000 AU. This ample region is spherical, heterogeneous to the traditional disk-like structure of the inner Solar System. This means long-period comets originating from the cloud can orbit the Sun from any direction. Consequently, it becomes unpredictable from which part of the sky we may witness the beauty. One of the well known comets (Halley's Comet) also prevails in this obscure region.

The total Oort Cloud may extend up to 100,000+ AU, meaning sunlight would take ~1.5 years to reach its outer boundary.

Finally, the Solar System gradually blends into the galactic environment, but the gravity of sun goes forth....

N.B. It never ends, but blends.

Wrapping up the final offline session of April on a truly high note.

From the depths of the ocean to the vast expanse of the cosmos touching the edge of the universe, today’s session brought together curious minds for an engaging and thought-provoking exploration of the unknown. With an unexpectedly strong turnout, participation, and enthusiasm of everyone present made the discussion about the creations even more meaningful and dynamic.

The session also included creative geometric practical problems, encouraging students to think beyond conventional boundaries and approach concepts from new perspectives.

We sincerely appreciate the active involvement and curiosity shown by all members.

Thanks to Rushlan Muhammad for conducting such a active session.

Whatever we perceive by the pair of our eyes or feel through the god gifted senses, is a kind of existence. Not only the creations within our sight but even the creations beyond the observation are 'Existence'.

In order to prove self existence, all matter doesn't require visibility. It's their will whether they'll interact with photons or not. All of god's creations are Autonomous, independent of each other. Again, some fluctuating particles appearing for once and vanishing instantaneously, are existences.

All creations of the Khaliq, which we might be aware of or not, are forms of existence..

And at a very acute length, there's a one dimensional phenomena as the core of the notion, which the theorists mention as the 'String'.

While exposing the string, unlike other monotonous theories, we can easily get it without any complicated math equations.

Core idea (1 line): String is nothing but one dimensional vibrating energy influenced by the shape of the curled up dimensions.

The string is just energy in vibrating state. Each of the patterns are observed as distinct matters. For instance, a kind of rhythm in an open string is matter 'A', while another kind of rhythm in a closed string is matter 'B'.

Now what's the 'curled up dimension' thing?

In order to understand, we should recall the example Brian Greene used in his lecture.

Look at any wire you can see nearby. It looks 1D from far away. When you come closer, there appears the width beside the length. The ant (assume) on the wire is close enough to discern all the 3 dimensions, as it can go round and round.

So what's the point?

The point is, when we zoom enough, there might be more dimensions. (At least 10 dimensions of space and 1 of time)

And those higher dimensions are curled up. Despite knowing it's curled, we don’t get the exact shape. But the shape (Calabi-Yau space) somehow influences the vibrations like the shape of a music instrument does to the tune.

You see, the vibrations are spontaneous but the patterns aren’t. And this is how the Calabi-Yau space dictates the string.

However, it was the summarized core idea of a hypothetical framework, and may be a meed if proven....

An idea not proven yet, but not negligible..

মুছে যাক গ্লানি, ঘুচে যাক জরা,
অগ্নিস্নানে শুচি হোক ধরা।

শুভ নববর্ষ ১৪৩৩ 🌸
Seroil Government High School Science & Mathematics Club' - SSMCএর পক্ষ থেকে সবাইকে জানাই বাংলা নববর্ষ ১৪৩৩-এর আন্তরিক শুভেচ্ছা ও অভিনন্দন।
নতুন বছরের প্রতিটি দিন হোক জ্ঞান, সৃজনশীলতা ও নতুন সম্ভাবনাময় ও সকলের জীবনে আসুক সাফল্য, আনন্দ ও সমৃদ্ধি ।

Congratulations, Mubarak Ahmad Khan!

বাংলাদেশের “সোনালী আঁশ” জুট শুধু কৃষির গর্বই নয়, ভবিষ্যতের প্রযুক্তির দিকেও নতুন সম্ভাবনার দ্বার খুলে দিচ্ছে। দেশীয় বিজ্ঞানী
Mubarak Ahmad Khan এবং Bangladesh Jute Research Institute–এর গবেষক দল জুটের সেলুলোজ থেকে গ্রাফিন তৈরির এক যুগান্তকারী গবেষণায় কাজ করছেন, যা বিশ্বজুড়ে “জুট গ্রাফিন” নামে পরিচিতি পাচ্ছে। গ্রাফিন হলো এক ধরনের বিস্ময়কর পদার্থ। এটি অত্যন্ত শক্তিশালী, অত্যন্ত পাতলা এবং বিদ্যুৎ পরিবাহিতায় অসাধারণ দক্ষ।

বর্তমানে সারা বিশ্ব Artificial Intelligence (AI) প্রযুক্তির উন্নয়নে দ্রুত এগিয়ে যাচ্ছে। কিন্তু AI পরিচালনার জন্য ব্যবহৃত সিলিকন চিপ খুব দ্রুত গরম হয়ে যায়, যা একটি বড় প্রযুক্তিগত চ্যালেঞ্জ। এই ক্ষেত্রে গ্রাফিন একটি সম্ভাবনাময় সমাধান হতে পারে, কারণ এটি তাপ খুব দ্রুত ছড়িয়ে দিতে পারে এবং ডিভাইসকে ঠান্ডা রাখতে সাহায্য করে।

তবে এখনই গ্রাফিন সম্পূর্ণভাবে সিলিকন চিপের বিকল্প হয়ে ওঠেনি। জুট থেকে গ্রাফিন তৈরির এই উদ্ভাবন বাংলাদেশের জন্য গর্বের, অনুপ্রেরণার এবং আশার প্রতীক।এ ছাড়াও তিনি পলিথিন এর বিকল্প স্বরূপ পাটের এক ব্যাগ আবিষ্কার করেছেন বহু পূর্বেই। আসা করি নানা জটিলতা কাটিয়ে তা শীঘ্রই বাজারে আসবে।

We are truly proud to see our club activities running so smoothly, all thanks to the incredible dedication and active participation of our members. Your enthusiasm is what drives us forward!
We believe this is just the beginning together, we will go even further and achieve greater success.

A warm welcome and heartfelt congratulations to all our new members! We’re excited to have you on this journey of curiosity, innovation, and discovery.

As the blessed month of Ramadan draws to its graceful close, Eid al-Fitr arrives not merely as a celebration, but as a crown , a moment where patience finds its reward, devotion meets its acknowledgment, and the soul rests in the warmth of divine acceptance.
It is the day we stand in gratitude for every prayer whispered in the dark, every fast observed in silence, and every act of goodness offered with a sincere heart.
Allah ﷻ reminds us in His noble Book:

"Indeed, with hardship comes ease."
(Surah Ash-Sharh 94:6)

Every hardship of Ramadan — every moment of hunger, thirst, and restraint — was never without its ease drawing near. Eid is the living proof of that divine promise.
May this Eid be a renewal — of bonds, of purpose, and of closeness to the One who carried you through every day of the sacred month.
Eid Mubarak from all of us at SSMC — Serail Government High School Science & Mathematics Club.
May your joy be as vast as the knowledge you seek, and your blessings as endless as the universe He created.

One of the Uniquely fascinating shapes we witness is circle, isn't it?

Well, what if anyone asks you that what makes the circle so unique?

So, let us begin from the defination.

Circle is a shape where every point of the circumference has the same distance from the center often referred as radius. And the longest possible distance between two points of the circle is diameter which is the double of the radius.

We might have noticed that the circumference gets larger and larger as the diameter grows..

So, circumference is proportional to the diameter..

Let us assume the constant looks like 'π'.

So the relation among circumference(c), diameter(d) and π becomes,

c = dπ

Or, π = c/d

So, we can see that π is nothing but a constant ratio of the circumference and the diameter.

And one of the most funny facts is that this is a "ratio" in word but 'irrational' by behaviour.

This cool looking constant appears almost everywhere of geometry. Special wherever rotation appears, π must be there whether exposed or hidden..

Many great mathematicians like, Madhava of Sangamagrama, James Gregory, Newton, John machin, Leibnitz, Euler gave different series for π. And specially Ramanujan who gave 17 different series which converged to 1/π.

So, this was a short story of a irrational ration🥲.

Well, goodbye

With the pi

Happy π = 3.141592653589793238...... Day.
