Next in who after the Ramanujan series?

At a tender age of 16, a brilliant but completely unguided boy from Tamil Nadu joined the National Defence Academy & was commissioned into the Indian Navy's electrical branch . He did not have the luxury of a quiet university setting; he was trained in practical skills to maintain weapons systems on warships.

But Arogyaswami Paulraj possessed an insatiable, self-taught obsession with the advanced mathematics of signal processing, control theory & information theory. He studied advanced matrices & random variables by lamplight on naval ships.

By the late 1970s, India faced a serious strategic challenge. After the 1971 Indo-Pak War exposed weaknesses in imported sonars, the Navy needed an advanced anti-submarine warfare system but was blocked by international export restrictions. The Navy turned to Paulraj, then a rising officer with a PhD from IIT Delhi (earned while still in service). He was tasked with leading a major indigenous project to develop a world-class hull-mounted panoramic sonar from scratch.

Operating under intense resource scarcity, Paulraj’s mathematical genius took over. He designed complex signal-processing algos that could filter the chaotic, deafening acoustic noise of the ocean to pinpoint enemy submarines. The resulting system, APSOH (Advanced Panoramic Sonar Hull), inducted in 1983, completely stunned global military observers. It did not just work, it outperformed contemporary Western systems.

After setting up major defense labs in India, Paulraj retired from active naval service & arrived at Stanford University in 1991 as a research associate. This is where the story shifts from military history to modern legend. While working on signal separation experiments for airborne military reconnaissance, Paulraj noticed a strange, fleeting physical phenomenon.

When a radio signal is transmitted in a crowded area (like a city with buildings), it bounces off walls & scatters into 1000s of chaotic, distorted paths. Engineers treated this scattering as a nightmare, multipath interference that corrupted data.

Paulraj had a paradigm-shifting realization rooted in multi-variable calculus & spatial matrices: What if the scattering was not a bug, but a feature?

He realized that if we used multiple antennas at the transmitter & multiple antennas at the receiver, we could use advanced matrix mathematics to isolate those scattered paths & stream parallel, independent channels of data over the exact same frequency, at the exact same time.

He called it MIMO (Multiple Input, Multiple Output).

When he 1st proposed it, the academic world mocked him. Prominent profs & industry skeptics told him it violated the laws of physics & information theory. They claimed it was mathematically impossible to multiply data speeds w/o expanding bandwidth.

Paulraj did no back down. He built his own prototype, founded a startup & proved the mathematics in real-world silicon. He designed the microscopic architecture, the microchip algos that allowed small devices to execute these hyper-complex spatial matrix calculations in fractions of a microsecond.

If we look at the device we are using to read this right now, look at the top corners of our screen. We cannot see them, but embedded inside the frame of our phone are multiple microscopic antennas operating on Paulraj’s exact MIMO-OFDMA mathematics.

Every single modern 4G network, 5G network & high-speed Wi-Fi router on Earth is built entirely on the mathematical foundation invented by the self-taught Indian Navy officer who packed his bags for Stanford. He did not just solve a math problem; he built the invisible highway that carries nearly 100% of the world's mobile data traffic today.

@damn_barbarian Totally agree. But in this particular strictness is applied only on students. No accountability for folks who messed up this exam !

Mindiyum Paranjum turned out to be quite the surprise package. I am not a fan of the lead pair, and the story is inspired by a famous short story, and yet, it clicked very well, thanks to some excellent chemistry, very good storytelling, and the setting. #malayalam #movies

[Mridul George @georgemridul]

@damn_barbarian Njanum orthu ! But teaser had references to aitheehyamala story..

[$hyju @linktoshyju]

Watched a lovely movie #MindiyumParanjum on Prime.. a feel good movie about long distance relationship… short and sweet movie… but this is not for the twitter elites or the one who has problem with Malayalam movies…for the rest definitely worth ur time

[rajesh @rajeshpalathara]

#MindiyumParanjum — The narration flows nicely between past and present. Not exactly a strong , but the actors make it a pleasant time-pass watch. Storytelling 👌🏼✨

#MindiyumParanjum (2025)-This Malayalam romantic drama is an interesting adaptation of one of my favorite popular old short stories (not mentioning the name on purpose), an intimate conversation piece of sorts between a couple as it reveals to us their story.

[Sharat @sharat3]

#MindiyumParanjum (2025)-A nice and sweet little ride down the memory lane of a long distance couple. The non-linear narrative and good performances by the leads make the journey worthwhile. The music is good too. https://t.co/AmaNJzCsqL

#Mindiyumparanjum A simple, cute film with no negative shades in the story. Neat and well settled performances by #UnniMukundan and #AparnaBalamurali make it a pleasant watch. A great choice for a relaxed family viewing on OTT.

#MindiyumParanjum

A soulful look at long-distance love that sometimes gets lost in its own silence

Gently captures the emotional landscape where love survives through patience & trust

The core of film lies in Unni - Aparna characters combinations which worked really well 🤍

@damn_barbarian May be they go to bed very late . After mobile phones became less phone and moreoyhrr things, everyone's sleep patterns have changed...

[Shiji Eldose @romachfilms]

Mindiyum Paranjum, starring #UnniMukundan and #AparnaBalamurali, is a heartfelt film about love, longing, and long-distance relationships. In an era dominated by larger-than-life and violent cinema, this simple film comes across as a balm for the soul. #mindiyumparanjum
