I can't express how true you are 😱 Even I also needed this video today only ! 'Cause today my teacher delivered an intro lecture to Thermal Radiations and Blackbody. And asked us to prepare for them in advance.
That's because you count the hits and not the misses :-) For hundred videos that didn't drop just right you picked the one that did. It's normal we all do that - brain is basically a discriminative detector with oversensitivity to certain features (e.g. faces).
@@LiborTinka But it’s very consistently perfectly timed for this channel’s videos, and he doesn’t have hundreds of videos, could be because they are releasing videos based on a common engineering curriculum
Your videos are always a life saver come exam time. It's remarkable that you're able to explain these complex concepts better in 17 minutes than most professors can in weeks of lectures. Thank you!!
You are an absolute godsend to all engineering students as 3blue1brown is to the mathematics community. These videos give the perfect overview for concepts that are initially hard to grasp with amazing animation and clear explanations.
one of the most pleasent animated videos I 've ever seen, as an electrical engineer, i'm not very familiar with transfer heat concepts, but your video made it all very clear! amazing!
I haven't felt the same about heat since I learned that it was an electromagnetic wave. And I thought it was heat. It just doesn't feel the same anymore.
@@melaniecotterell8263 Heat can be transferred in primarily 3 ways Conduction, Convection and Radiation and in Radiation only it is transferred as an EM wave and in other two cases it is different.
Your videos are a life saver for an engineering student like me. Before I even read lecture slides I check if you have a video on the topics, you truss and material sciense videos are amazing. Pls don't stop and thanks you
I wanted to learn 'what a blackbody is' when I clicked on this video. This video blew my mind away & I enjoyed every second of it. And oh yes, I also found the answer to my question
You are bringing a revolution to Engineering Academics and I feel I am fortunate to be alive in this era of revolution. Our successors are going to be so much lucky, we aren't less tho.
Nice video and well explained. I wish this had been available back in the stone age when I was learning this. Also, I wish there was a way to give a "thumbs up" & comments for your Nebula videos like the "Understanding Dimensional Analysis" video you mentioned -- it's quite good. I remember learning & using it a lot in college and at work too.
Dude I really appreciate your work. It doesn't matter to me what topics you cover in your videos but they're very easy to understand and interesting. Thank you
What i find really ironic, is that this channel seems to upload the exact topics I'm covering in my classes as they go up. I just got to the radiation portion of my heat transfer class last week.
I wax studying heat transfer by radiation from text book.... It took me 2 days to complete the chapter with still unclear concepts .... You made the video on the exact time and cleared all concepts in 15 mins... Beautiful... 💖💖💖💎💎💎💐💐💐.... I will be very thankful to you if ypu post ypur video of dimensional analysis here on RUclips... Please we need it badly...
What a coincidence, I just decided to learn about Quantum mechanics for fun, and this video is uploaded within hours, the graphics are so beautiful too!
Great explanation. Every second of the video is finely crafted , all the visuals are so perfect !!! Wow !! 👏Thanks for providing such high level content. Just Fabulous 🤩
Hey, now I'm doubting. How do you know that next week I have an exam on Heat Transfer...!!! Well done bro... A truly exceptional work from a mechanical engineer for mechanical engineers.
This video will not help you calculate answers to heat transfer problems. That is why you have a 15-week intensive curriculum in one topic of study. He needs to do a video on Thermodynamics which is nothing like heat transfer Thermodynamics is confusing, How and why a gas heats when compressed. That's most of it
@@melaniecotterell8263 sometimes, understanding how things work truly help solving a problem, because all of a sudden you understand why using a specific formula over the other and all that kind of stuff.... At least that how i feel. About the temperature thing, the temperature of a gas is greatly affected by 2 factors, volume and pressure, Tou can see it in the ideal gas law, PV=nRT... The more intuitive explanation is that as u compress a gas, the gas particles bump into each other more and more, which give the gas more kinetic energy which raise the temperature!
Awesome video as always! Thank you so much for this great work! I would just precise that the EM wave do not only follow straight lines within mediums, which explains mirages for instance. And that there is at least a fourth way the heat can be transfered between objects, which is by being carried along within moving matter : transportation.
@@darylh8657 I meant solid matter . I think convection is a term only used for fluids. For instance an ablative thermal protection on a re-entry vehicle. Small solid bits would detach, moving the heat they carry away from the spacecraft.
Sir please start making vedio . Your style of explaining is just amazing. I don't know how to express it in word's but really your vedio helps us a lot❤
@@400_billion_suns Yes, I meant that the material of the radiators (its ribs) has to be both emissive and reflective, in order to reflect heat from the neighbor radiators (otherwise - a large and, presumably, a heavy sphere).
If I have a THIN hemispherical shell that is recieving heat from a source at its center, would both it's inner and outer surface be considered in area term? Does the term THIN has anythjng significant to do with it? Considering that for a thin sheet of charge, we consider it to be 1 surface of charge in all.
Stefan Boltzman is one of the most counter intuitive laws in physics.. It begs the question, how can a measure of energy flow be proportional to Temp to the 4th power when Temperature itself is a measure of internal energy. This needs to be explored in more detail.
There is nothing counter intuitive there. High temperature body emits faster energy. The body cools down as it releases energy and therefore the temperature drops and energy flow becomes slower. Regarding the 4th power temperature, the formula can be derived by integration of the equation of Max Placnk black body radiation curve.
If you're accounting for luminescense you may be cutting things a bit too close. Give yourself enough margin so you don't have to worry about that shit. When it crashes I'd hate to be the one who miscalculated the luminescense. Poor pilot didn't have enough light to navigate around the obstacles. Too much luminescense will get you a headlight ticket. Always best just to go stealth when space truckin'. Look at those stars.

@The Efficient Engineer What software do you use to make the videos?
Where is your next video? I hope it's engineering drawings.
Have you stopped making videos for this channel??
Nope! Next video on Tuesday!
Its unbelivable how these videos drop just at the instant you need them. Thank you so much!!!

One of my favorite RUclipsrs ever. His videos cover essential topics in short time without leaving out important aspects of it.
holy fuck... i got goosebumps when he said "this is why object glow when heated."
i've never questioned why hot object tend to emit visible light.

literally don't have words.......the way you explain is unmatchable and unbeatable
I have no words to describe how good this video was. This channel is an absolute 💎 . Thankyou 💟
As always this channel releases video's on the exact topic i am currently studying days before finals. Great content!
alright, this was one of the best science videos i've ever seen
This video really cleared my concepts. A heartiest thanks to the team members of this channel.
Whenever I watch ur channel, I feel like why the heck did I not find u during my college.
What i find really ironic, is that this channel seems to upload the exact topics I'm covering in my classes as they go up. I just got to the radiation portion of my heat transfer class last week.
These are honestly the best science videos in youtube.
Your channel is a blessing. Such beautiful animation, and simple straightforward explanations. Wish I could subscribe twice
This Video is One of the Best Pieces of
Actual Content I have Watched. 😊👍🏽

Best animated video on thermal radiation with proper explanation. Thanks a lot.
Whoever made animations for this video did a great job.
I am highly impressed by this RUclips channel and look forward to more uploads!
Love this channel :D
What a coincidence, I just decided to learn about Quantum mechanics for fun, and this video is uploaded within hours, the graphics are so beautiful too!
Perfect explanations.
I love how you leave room for the information to seep in before moving on 👌.
Such a great video. The concepts are explained from the ground . Thanks
Just as I'm working on a thermal radiation problem. This helped me visualize this topic so well. Thank you!
There are extra blankets in the closet. Visualizing warmth will not make you any warmer. NFW.
Excellent video. Hats off to your channel. This channel will get millions of subscribers I bet
Great explanation. Every second of the video is finely crafted , all the visuals are so perfect !!! Wow !! 👏Thanks for providing such high level content. Just Fabulous 🤩
You're a beautiful teacher of principles and content, thank you
this channel is a gold mine
U r the best I HV ever seen in my life like u ,all semester lessons in less than 20 min wow, take a bow 🙏

Thnx a tonne! I was learning this from Bk Dutta and was finding it very difficult to visualize. You've saved my life!!
This is basically a nice video summary of the radiation chapter in incropera fundamentals of heat and mass transfer 😅Very usefull!!
It’s very efficient to Learn from your video, it summarise all concept or build a physical understanding of topic
Please increase your rate of uploads. The world needs many more such type of quality videos.
Awesome video as always! Thank you so much for this great work!

WHAT! I have an exam on this soon. What a good timing!
Thank you. This is a bit advanced for me in high school but i didnt understand my book. This helped make my understanding deeper. I like this
Please keep doing these videos, they are really great
Another MASTERPIECE educational video from this channel. Thank you.
Great video. Coincidentally started to review radiation for my thesis today. Came in as a great motivator :)
Clear and concise. Not rushed.
I like it.
Thanks
It sucks that this channel didn't exist when I was in school. Else I probably would be an engineer by now. lol
Great channel, keep it up.
Sir please start making vedio . Your style of explaining is just amazing. I don't know how to express it in word's but really your vedio helps us a lot❤
How simple our life would be if our college profs could teach like this or just play this video in the class should be enough as well..
Perfect! Exactly what I wanted right now! Thank you so much, your videos are always amazing. 👍👍
This colors... this animations... PERFECT!!
WE can wait for such type of content... keep it up sir.... 😄
Now I see how and why there are big challenges in designing future spaceships with powerful nuclear reactors. Thank you for this video.

Awesome video, my new favorite refresher
This was another great video. It would be cool if you could cover convection and conduction as well:)
you summarized all the stuff i need thank you so much 😍
If I have a THIN hemispherical shell that is recieving heat from a source at its center, would both it's inner and outer surface be considered in area term? Does the term THIN has anythjng significant to do with it?

In your descriptions, can you put the required education for better understanding? Math level, the Physics level. Thank you!
i think AP high school phy is enough
amazing video, you are saving my life before my final exam!!!!!
I am getting commercials about shaving nether regions whilst watching this great video. Talk about a mind-shift.
Amazing video. If only it'd been uploaded back when I was in high school 😅
As always superb. Can you please make video on acceleration and velocity analysis of mechanisms.
such a good video. keep it up man!
Thank for great video of heat transfer by radiation.
so useful
A great feeling to learn physics... thank you for the team...
Should make one on CFD
very good
a beautiful, make sense video
Please do some videos on Fluid Mechanics.
Best channel ever
Please do a video on explaining more fluid mechanics concepts..Where one need visual explanation for clarity about the topic.
Hope you do ❤️
Great channel for revision.
Great way of explanation
Very good video. Could you cover up more topics on heat transfer?

You should do heat transfer series!!! As always, your video is awesome!!!
may be you can make 1 more convection to complete 03 heat transfer modes :D
Great animation bro
Your videos are awesome! You should make one on compressible flow
thank you so much, this video is brilliant
