Finally after 5 years of Maths and fun, I will be retiring for MO. Throughout this journey, there have been countless ups and countless downs but one fact remains - This has been the greatest period of my life. From the boy on telegram to boy on IIMOP writing this post, the journey has been peak. Thank you MO for supporting me through the darkest of days, the most harrowing of nights and the greatest of occasions. Thank you maths for giving me life. A final tribute to maths and maths olympiad from my side... Enjoy this MO SLANDER y'all, and thanks for being a part of this journey. A huge thanks to @Deb for helping with the editing and finally, goodbye... Maybe we will meet again in the future. Hope you enjoy and have a happy life :). For the ppl upcoming, all the best for your future, may you enjoy MO, as much as I did!! https://youtu.be/dz1DJTx40jc

Hey people! All the best for IOQM. The last for most of us and the first for a few... All over our lives the thing we have hated is now standing in our way one last time. An exam hated for a long time is now in it's old and feeble state looking forward to retiring us or retiring itself from our lives. Tomorrow will tell what will come to pass but one thing which will is I will surely enjoy IOQM this last time, more than i ever had... In 20 hours, I will be free from IOQM and maybe all of MO forever, but these 3 hours will be something which should stick!! All the best again... Let's crack it ig...

In structural chemistry, many molecules or ions (such as benzene, or the carbonate ion, cannot be accurately represented by a single Lewis formula. Instead, we draw multiple valid Lewis formulas called resonance structures (or canonical forms) and describe the real molecule as a resonance hybrid with intermediate bond lengths and properties. Can chemical resonance be accurately thought of as an example of quantum superposition?

How much do you guys know about string theory and the math used in it?

"Sometimes it's ok to let go" 😂😂

A pretty undetailed post just to provide initial context

It is said that the curl of a gradient is 0 or specifically: ∇ x (∇T) = 0 This also shows that energy is conserved mathematically... Then why is the Noether's theorems required?

Ok guys explain to me what a tensor is...

A historic sweep for the Indian IPhO 2026 team, with all 5 members getting a gold. Congratulations team India and join me in congratulating one of the gold medalists, @RiddheshAB7... Moving on to the International Mathematical olympiad 2026, which is being held in China! All the best to team India and the world. Lets hope for one of the best problems to come on the 15th and the 16th July 2026...

The cosmological principal states that on a large scale, the universe is homogeneous (uniform in density) and isotropic (looks the same in all directions). This is a crucial fundamental assumption by astronomers and cosmologists, which provide many shortcuts in studying the universe. For example, physical laws which apply locally, apply universaly as well... We do not need to derive new laws of physics for every distant galaxy. This principle was also key in foundation for the standard model. By applying the principle to Einstein’s General Theory of Relativity, scientists formulated the Lambda-CDM Model, which accurately describes a universe that expanded from the Big Bang and contains both dark matter and dark energy. However a recent journal in Nature, challenges this core principal.

We're back

Telegram is banned in India until June 22, 2026. Looking at the harsh conditions of Telegram in India and obviously the incapability of the government in conducting national exams, telegram may face permanent ban at any moment. This audience is very dear to me and I wouldn't like to lose you all. So I would request you to subscribe to my YT channel, so that we can shift there, if TG is ever banned... https://www.youtube.com/@aryandas5643

The Sun radiates energy continuously into cold space at temperature ∼3K, yet its core remains at roughly 1.5×10^7 K for billions of years. A naive thermodynamic argument says: “Hot objects lose heat, therefore they should cool.” However, stars do not behave like ordinary systems. Explain why a star can radiate enormous amounts of energy for billions of years without catastrophic cooling, and why, during some phases of evolution, losing energy actually increases the core temperature.

I was ofc checking you guys! The real answer is 0.1 Mpc. Hubble's law won't work here because the universe isn't isoprotic and homogenous throughout... Considering the galaxy is a milky Way satellite, the only possible distance is 0.1 Mpc... Get skills ppl
