This video is simple, elegant and just the right length. I feel like I learned something foundational that I will actually remember and be able to apply.

I am honestly at a loss of words, you're the best teacher i encountered yet highly underrated. I hope you make it big. You seriously helped me a ton

Hi, thank you so much for these beautiful words. They made my day ❤️

[@nimishajain2911]

You are an amazing teacher and you tuber. Thank you for the time and energy to create these. I’m really enjoying these and learning new concepts fast.

[@PhysicsMadeEasy]

Hello Nimisha, thank you very much for the kind words, and recognition for the effort I put in scripting, shooting and editing these videos! It's really worth it: my goal as a teacher is to open young minds to the true amazement that Physics provides, and all the feedback I get from online and real life students shows me it works. When you dig a little, reality is more stunning than fiction and that, by far ! I checked your channel, your english is amazing! I have a few Indian friends and I never heard a native Indian pronounce English with such a clear accent (you are more intelligible than I am, and English is one of my mother tongues). Congrats.

Great video! Beautifully explained, connecting all of the dots! I'm a university student studying Engineering ,and have a first semester course on Quantum Mechanics and this video really helped me visualise and understand this topic qualitatively, making the mathematical and quantitative side much more intuitive and easier to continue! Absolutely loved this lecture! Keep it up! Continue delivering such top notch content, and keep up the good work. Appreciate all the efforts! Was really interesting! You're positively impacting a lot of young budding minds out there! Keep sharing! :)

[@PhysicsMadeEasy]

Thank you Nikhil. I am glad you find my content useful. "Positively impacting young budding minds" is the one of the aims of this channel: to show them that Physics is not that difficult, by explaining stuff that can allow them to make sense of what they are taught in the classroom.

I'm hear to understand the physics of climate change. Stefan Boltzmann's law is an important law at the center of this.

[@PhysicsMadeEasy]

Absolutely Kiren, The Earth is a black body at a temperature such that it emits its radiative energy in the Infra red region. This infrared radiation is what allows some of the bonds in molecules like CO2, H2O, CH4 to enter resonance (the IR is absorbed). This oscillation of the bonds generate the same IR radiation emitted in all directions, including back on Earth... heating the earth a little more.

[@PhysicsMadeEasy]

Thank you Mr Gammer! You believe you have the potential to become another Einstein... haha! Maybe. I was really bad in physics in high school because of the lack of quality of the teacher's pedagogy. I mean really bad: I came very close to quit school. I held on , got the minimal mark to pass the high school final exams. Luckily, during the two first years of at Uni, I met amazingly good teachers which made me realise that Physics was actually not that difficult. And my grades exploded, and I went beyond the PhD (post doc), always getting honors on the way. That near-miss I experienced: this is why I became a teacher :-).
