Exploring Quantum Day: Celebrating a Century of Quantum Mechanics

World Quantum Day

March & April are months full of days set aside for this and that. As though humans sat up one brilliant day in spring and decided to take notice and give gratitude for the world.

March has Read-Across-America, Women’s Day, Pi Day

April has Poetry, Earth Day, Quantum Day, International Dance Day

Last night, I came across the two geeks in the house looking rather pleased with themselves and clamoring for me to come and watch something. I sighed and made my way to them. Chores were hanging all around me. The clothes, the dishes, the putting-things-away. Everything remained to be done. Now was not the time for frivolous you-tubing and insta-reeling or whatever it was the pair were up to.

But relentless is a word that could be used I suppose. 

So, there I was, half enjoying the look of these fellows watching me enjoy the video, and half-absorbing the video myself. 

The video showed a wave pattern that could explain the wave motion dynamics that seems to keep electrons in orbit. 

The Miraculous from the Material – Understanding the Wonders of Nature – By Alan Lightman

“Interesting! That’s just what I was reading about. Talk about coincidences.” I said pulling the book, The Miraculous from the Material – Understanding the Wonders of Nature – By Alan Lightman. In the essay on atoms, he had written about this very wave concept:

“Quantum physics has shown that all particles behave partly like water waves. They don’t occupy a single point in space, but instead have a spread.”

He explains in the essay about a group of scientists at Cornell University led by David A Muller, and how they set about getting a high resolution photo of atoms. 

They used a computer to simulate the scattered electron waves overlapping with one another, and used that to reconstruct a 3D picture. The process is called Electron Ptychography, I said.

Curiouser-and-Curiouser

“Only you would be reading about this when we show you a video!” the son chuckled, and I have to tell you, I was quite pleased at the serendipity of it all too, and babbled on.

“Did you know, last year, 2025, was officially 100 years since Quantum Mechanics entered regular fields of study? Also, 4/14 was chosen as World Quantum Day because of Planck’s constant value?” ($4.14 * 10^{-15}  eV.s?) I said , and the fellow looked thrilled at this piece of information. “Curiouser-and-Curiouser, huh?”

“Yeah! I think this will be my favorite geek-day from now on, Amma. Suits me better than Pi-day no?” I laughed and agreed. 

Happy Quantum Day!

The Magic of Rain & Light

The past few days have been days of unimaginable beauty in the Bay Area. They have been rainy days. Rainy days in the Bay Area are a different kind of beautiful. For it rains, it pours, it drizzles, it teases, it dances, and it drums and sometimes just goes away. Occasionally, if you are really lucky, you can see a rainbow or two. 

One evening, the son & I wrapped up and went on a walk. It was a windy day, and temperatures tend to dip a bit more than usual on windy days around the time of a sunset. The clouds were so thick and ready for some rains, that we knew we would not be gazing at the sunset exactly. Still, that time of the day seems to beckon one, doesn’t it? Something about it makes it feel sacrosanct. 

Feeling Bubbly?

We chatted about this and that. Mostly of the experiment I had done with the children at the school I had volunteered in. Our experiment with air and whether they have force, culminating in blowing bubbles were a thumping success if the joy, laughter and smiles were anything to go by. We blew small, medium, big and humongous bubbles into the air. It is an amazing feeling when volunteers, teachers & the children have a great time. I told the son as much, and he grinned with what I knew was not just indulgence but genuine happiness for us.

Shining With Divinity?

On the way back, a beautiful trick of the light meant that the world behind us glowed golden through the clouds, while ahead of us, it glowed silver through the clouds. The pair of us stopped our chattering, and smiled together. Both of us stuck trying to find the right word for the light. Maybe even wondering how to catch this moment in a literal bubble. For it was so beautiful. 

“Divine light, huh?”

“Yeah! I don’t think I know exactly what that light is, but this comes closest no?” the son agreed. 

Light is such a beautiful phenomenon. We spend our lives trying to hold it, we have endless literary devices around it (Light at the end of the tunnel, lightness of being, making light of a situation) – But always, it is in a positive light (huh!) 

Rainy days bring out the beautiful potentialities for experiencing light. It can evoke melancholy, gratitude, divinity, surrender, and most importantly awe. 

Rainbows

When the raindrops manage to create total internal refraction, there is nothing but joy, wonder and an overwhelming sense of loving this beautiful Earth with its thin blanket of an atmosphere that allows us to experience rainbows. 

On Sunday night, I snuggled into bed and read heartily the essays on the atmosphere, bubbles and rainbows from the book: The Miraculous from the Material – Understanding the Wonders of Nature – By Alan Lightman.

That seemed like a marvelous way to say goodbye to the rainy week-end. How was your week-end?

Celebrating World Quantum Day: History and Fun Facts

World ⚛️ Quantum ⚛️ Day – April 14th

“Oh wow, ma! Today is Quantum Day!” said the son. Actually yelped the fellow, like the words were yanked out of him by the excitement coursing through him. For some weird reason, even as a young toddler, he loved the word, ‘Quantum’.

Maybe it was Iron Man or Ant-Man – that movie in which they use the word ‘Quantum’ every time they did not want to explain something. Or maybe it was the fact that we all liked watching The Big Bang Theory television series in the house so much when he was a child, or maybe the Cosmos shows by Carl Sagan, or the fact that I like reading about Physics. 

In any case, Quantum. He lights up when you mention Quantum-This or Quantum-That. 

I smiled at him, and said, “Wow! I didn’t know they had a day for that!”

2025 is also the International Year of Quantum as designated by the United Nations. 100 years since Quantum Mechanics became a part of higher education science and research. 

From Book: My First Book of Quantum Physics – by Sheddad Kaid-Salah Ferron & Eduard Altarriba

⚛️  My First Book of Quantum Physics ⚛️

This seemed to call for a little nostalgia. I opened a favorite book of ours – as a child, I remember getting this for him and he spent hours looking through the pictures. 

My First Book of Quantum Physics – by Sheddad Kaid-Salah Ferron & Eduard Altarriba

It really is a beautiful book. Sheddad Kaid-Salah Feroon & Eduard Altarriba do a fantastic job of the illustrations, explanations of difficult concepts and providing a general feel for the subjects.

It is why we were excited to visit the CERN supercollider in Switzerland.

Sheddad Kaid-Salah Feroon & Eduard Altarriba have a series of books covering topics such as: 

  • Quantum Physics
  • Relativity
  • Electromagnetism
  • Cosmos
  • Microbes
  • Evolution

Please check these books out if you get the chance. It is always fascinating. Especially, when in our everyday lives, even if we are professionals with science backgrounds, we hardly set aside the time for this type of shoshin (the wonder of the beginner’s mind)

In one time and place, when not observed, if we can find that joy of wonder, that would be Quantum, wouldn’t it?! Get it? Get it?!

2-d Meditations in our 3-d world

T’was a week-end that I was looking forward to. Which meant I looked forward to sleeping in. The son, however, has an internal alarm that seems to work contrary to social expectations.

yawn

Anyway, the point is, the son came up bright and shining. I lifted my tub from the covers and moaned from under the covers at his exuberant greeting. Hmmm….Hmmm…..AAAyyynnsnjsjfhsjfh!

He bustled into the room carrying a suspicious looking questionnaire. Just as I thought, the blasted thing turned out to be a Physics quiz that started with the question:

“What holds the quarks together in the nucleus of an atom?”

Luckily I knew the answer to that one (gluons), but it went downhill from there.

By the time we had arrived at the last question, my weak force was battling with the gravitational forces holding me down on the bed, and I sprang out in one gravity defying leap showing a strong force I did not think I was capable of, and hustled the little fellow and the husband out on a hike. If I was going to survive any more Physics quizzes on quarks, I needed to get my spark. 

The discussion on his favorite topics led us to the fascinating topics of dimensionality, and I told him about a particularly fetching piece on Flatland geometry in the book, How The Universe Got Its Spots – By Janna Levin.

Flatland is a fascinating piece of work written by Edwin Abbott Abbott in 1884. He imagines a two-dimensional world in which all occupants are lines, flat shapes or circles, and also examines a social construct with this premise.  (People with more number of sides occupy a higher social position, with priests being circles. In Victorian times, women had no ways and means to careers, and therefore were represented as lines in that universe.)

https://www.youtube.com/watch?v=-wv0vxVRGMY (Carl Sagan explains flatland)

https://en.wikipedia.org/wiki/Flatland

That day on the hike, we went up and down the hills in the beautiful three dimensional world we live in, discussing what it would be like in Flatland.

In our everyday lives, rarely do we stop to think of flatland fantasies, and when we do, it is all the more magical. I mean how would a sunset look in Flatland? What would a sunset look like if we were in 4 dimensional worlds? Is our entire existence just us passing through this 3 dimensional world?

The gluon quiz master was, in the meanwhile, practicing his martial arts as he spurred himself through the hills, chipping in here and there, while listening fascinated to the Flatland theories. “Umm…Wonder whether that happened to Ant-man when he went into the quantum world.”

Wandering along by the waterside, watching the wind rippling the waters, and rustling the leaves in the trees nearby, it was beautiful indeed to occupy oneself with thoughts of how a wind would be in Flatland: maybe it would be like an earthquake to 3-dimensional creatures such as us. Maybe our cosmic upheavals are the breezes of the 4th and 5th dimensions. Who knows?

“Imagine, if you were an orange, trying to pass through the two-dimensional world.”

You could only see a dot as it touches the surface, and then a circle as it passes through flatland, a circle that gets bigger and bigger, and then recedes in size. Smaller and smaller till it becomes a point again and then disappears altogether.

Just as an orange cannot ‘get up’ from the 2-d world,   we cannot flit in and out of our 3-d worlds. But imagine if we could. If we could give ourselves the gift of perspective (that is another perspective –nature and our vast cosmos give us a fair sense of perspective already, if only we care to look and reflect of course)

Flatland

I am sure scientists who are spending their entire careers contemplating questions such as these are far more qualified to answer, but the very act of thinking seems to be a marvelously magical act. We admired our fellow creatures on our 3-dimensional walk in the hills: The geese, pelicans, seagulls and hawks.

Does a laugh in Flatland cause ripples? Do our laughs cause the butterflies to flit?

“Here is a joke for you”, I said on  the topic of laughs in inter-dimensional space. “What do you call a seagull that flies over a bay?”

“A Bagel – get it?” (a colleague’s joke!)

The joke was met with moans and laughs alike.

By that same extension, are all our lives just us passing through this 3-dimensional world? Where does Kung Fu Panda meet  interdimensional Physics and the Tao of Being?

I shrugged my 3-d shoulders. How quickly the contemplation of the physical world morphs into the philosophy of being? How easily our thoughts can become magical?  

Buoyant Force, Tensile Strength & Parasailing

To think that we would leave Puerto Vallerta, Mexico, without the pleasure of para-sailing was gnawing at the old heart. I mulled the thing over and decided that the best thing to do was to ask the valet who was greatly impressed with us, to holler and let us know when the parasailing man comes around. Apparently, he was not one early to rise and early to bed. He took his time and came around noon. I like folks like that in general, for I am not exactly a lark. It isn’t too much to say that had I been born a bird, I would have lived life thinking shriveled worms were food and that too becomes hard to come by as summer progressed. I may have tweeted from the trees to all who could hear about the sad state of affairs, but gone on to peck at wild grains and enjoyed myself anyway. But the problem was that we were to leave for the airport home-bound at 1 p.m. and if the Parasail-er came at 12 noon and then, had to go through his waiver forms and insurance checklists where would that leave us?

The husband looked at me amused. “Forgotten we are not in the US have you?  I don’t think this guy is going to bother with forms, documents and waivers. “ said the husband in query to my quizzical expression. The sun shone down and hope raised its beautiful head and sailed along side the distant parachutes in the sea once more. At noon, two men came dragging a parachute behind them. That was my cue. I ran on the beach towards them. It looked like another lady was going toward them too and I knew that if they took her on, both of us had an even slimmer chance of parasailing that day. The morning’s practice run had done me a wave of good and I pumped through the sands as fast as I could waving my hands in the air and trying to attract their attention. I have been seen to better advantage certainly, but that did not deter me. Shy birds don’t catch worms or get their fills of wild grains for that matter.

Now, let me give you a bargaining tip : Don’t let on that you are eager to have something when you negotiate price.

You are welcome.

When I reached the men, and asked them to state a price, they grinned. The sun caught the gold glinting in their tooth filling, and their eyes sparkled. They knew this customer was in the bag. None of the little tricks around not wanting it really, but doing a good turn to benefit the tortilla-winner of the family. No Sir. I still tried, so half-heartedly that they smiled even more, and said, “Come. Come Señorita. Just give big teepps okay? Big teepps.” (Tips)

I smiled, consented and dutifully pulled on my look of intense concentration to listen to the training they were to give me before the adventure. The husband turned his head by 3 millimeters and I knocked his knuckles and asked him to concentrate too. By the looks of it, there was a life jacket, but it was not one of those life jackets that instilled confidence in the wearer. The straps were broken for one thing, and for another they did not look buoyant enough. Not that I weighed the thing in air and studied the difference of displacement in water or any such thing, but I just knew. For another, if I fell into the ocean from  a height of 150 feet, life-vest or no, buoyancy force calculated or no, the shock of it would have me convalescing for a goodish amount of time. Obviously, I wanted to understand what to do in case of change in wind directions, changes in pressure or if the sea below grew choppy. There was a tiny boat that had a slimm-ish looking rope attached to the parachute. Somehow, everything the men said to make me feel as ease were doing the exact opposite. (Señorita! Very safe – new rope. Just 5 months old. Just give big teepps and I bring you down safely okay!) The mind boggled to think that depending on the tips, the rope could let you plunge into the ocean or be sturdy enough to get you back to land. But the Apparently-Brave do not dwell on the ratio between the tensile strength of ropes and tips.  They fly.

The sparkle in their teeth and eyes were a little distracting, but a butterfly could have grasped the directions, for that was all the time it took.

“When I whistle you pull right shoulder rope okay Señorita? If it is becoming dangers, then I whistle again and you pull left side rope. Simple. Okay start now.“

“What? No No. Wait. That’s it?”

“That’s it – very easy. Very safe. Just remember teeppz.”

“What if I hear a third whistle?”

“I whistle only two times. How you will hear three whistles?” he said with a kindly expression that one adopts while talking to the idiot child.

“Okay okay. Fine! What if I don’t hear your whistle? I am going to be 100 feet above the ground. “

“Don’t worry Señorita. We are there. We will get you down here.”

I saw there was no point arguing, so I nodded and the next moment the boat took off into the ocean and the parachute lifted. Higher and higher it went taking my spirits with it. I looked around whole-heartedly enjoying the views from up there. The heart beat a little faster at first, but then settled into a steady, euphoric state that I could get used to. Maybe this is what people say when they say that they dip into their inner selves and experience pure joy. I gulped the salty air, drank in the fantastic views and lifted my hands in a smooth glider-like motion and at once a great feeling of gratitude filled my heart. To have experienced something like this is pure joy.  I have since had the pleasure of talking to a wonderful person who attempted parasailing at the age of 74, and she whole-heartedly agreed too. This feeling is there to dip into whenever you choose.

That is some other person parasailing – a picture I had taken the previous day while lolling around with a book

I can’t say that I looked forward to the pull-right-strap-on-first-whistle (or was it the left strap?) part of the landing, but when I saw that I was nearing land again, I tucked in my nose and stuck out my ears as hard as I could to hear the whistle. Right enough I heard it and then, I heard the second one too. So, I used all my strength and tugged on the left and right or the other way around.

Wonder of wonders. The husband had apparently set their mind at ease on the tips they could expect while I was flying, for had I not seen such a smooth landing, I would not have believed it possible. I landed on the exact spot from which I had taken off and that too like a butterfly descends to sit on a flower. I gave them a delighted and effusive ‘Thanks’ and asked them to give the husband the same experience. The older of the men, touched his hands to his heart ( What is Mexico without a touch of melodrama?), and said, “I will do for him also Señorita.”

The men beamed with the teeeeppppzzz and we floated back to the hotel to pick up our belongings.
