The Cosmic Glow: Unveiling the Secrets of Blackbody Radiation: From Stars to Light Bulbs

Have you ever noticed how a stovetop burner glows red when it gets hot, or how the sun emits a white light? We have so many such phenomena around us in our day-to-day lives like- Light Bulbs – The filament inside an bulb heats up and glows, emitting visible light and infrared radiation. Molten Metal – When metal is heated in a forge, it first glows red, then orange, then white as its temperature increases. Electric Toaster Wires – The heating elements in a toaster glow red-hot as they emit thermal radiation. Lava from a Volcano – Freshly erupted lava glows red, orange, or white depending on its temperature. Stars in the Night Sky – Different stars appear red, yellow, or blue due to their surface temperatures, following black body radiation principles. A Fireplace Ember – Burning wood or charcoal glows red as it emits infrared and visible light. Infrared Camera Views of Warm Objects – Even objects that don't visibly glow (like human skin or animals) emit infrared radiation de...

The Uncertainty Principle

    The word "Uncertainty" is the most common feeling we all face in our daily lives. It does not refer to any negative situation; rather, according to "The Cambridge Online Dictionary," uncertainty is a situation in which something is not known or certain.  Let's consider the situation "You wrote an exam and waiting for your result." It's a good example of an uncertain situation in which you don't know about your result at a particular time. Simple, na.   Let's think about the situation in a deeper sense.  To think better let's make some changes in the situation now the situation is " You wrote an exam and waiting for your result. The result was out and suddenly your internet is not working". In this situation, you are unable to check the result online and also unable to contact anyone for the result, so the situation becomes that your friends know your result but you don't know. The point here is at that particular time ...

Idea of Superposition

Let's start with a question, "Can I be in a different position at the same time ?" Obviously - No. Ok, let's ask the question more specifically, "Can I be in a mood of happy and sad at the same time ?"  🤔🤔🤔 Well, we can say many times in life we are not actually happy or sad, if we try to measure on a scale starting 1 with sadness and 10 with happiness, we may be in between 1 and 10. Let at 1 sad,  2 - 4 is more likely sad, 5,6 neither happy nor sad,  7 - 9  is more likely happy and at 10 is happy. Have a look at the following table and graph - (Scores actually represent inner psychological feelings) So for the whole day, since the average of all scores is 7, we can say more likely happy is the experimented mood, but if we see the data locally it does not say so, it can say we are in some ups and down combination of happy and sad (like a wave spread in a whole day). Two clever observations I would like to mention here, 1. As I mentioned earlier, although ...
