I remember Mahesh sir teaching me in 2015 at Mahesh P U college. What a realistic class it was. He is one of the best teachers in physics. I completed mechanical engineering from St Joseph's and then advanced mechanical engineering from the University of Liverpool and I now still enjoy watching his videos. He is our true inspiration.
Sir, you are the best teacher I ever seen. The way you explain things, the words you used, even the reaction you showed when you describe things, the questions you ask and the way you answer it, all are amazing. Thank you! From Ethiopia.
You're learning about pedagogy a lot and even making us understand that.. if somehow every teacher knew this technique our country would have been at the top level, KEEP DOING THAT GREAT WORK👍
During the lockdown, I used to watch your physics videos together with my friend on google meet or discord. We kept MS Whiteboard open in the background. And everytime when you asked the viewers to think over something, we used to discuss it and try to solve it on our own on the Whiteboard app. It helped us a lot to understand concepts. (The first video we tried this on was wave optics: reflection)
I just wanted to say thank you for all the amazing videos you make on Khan Academy and UA-cam. I've been following your teachings for a while now and I'm really impressed by how much effort you put into your lessons. Your love for science is so contagious and your teaching skills had me hooked on watching the lectures for hours. I've learned a lot from you but the most important thing I've learned is that being a scientist isn't just about getting good grades on tests, it's about being curious and actively engaging in the process of discovery. You've taught me that it's okay to be wrong and to think about why I was wrong, and how to find the right answer. Your teaching has helped me understand that science isn't just about getting the answer, it's about the process of finding it. I'm really grateful for how you've helped me understand and appreciate the beauty of science on a deeper level. Your videos have inspired me to want to pursue a career in science and I'll always be thankful for the impact you've had on my life. I hope more people get to see your videos so they can also rediscover their love of science.
Wow, Udhav that is so deep man. Thank you so much for sharing this with me. Not only did the comment make my day, but it also keeps reminding me why I do what I do. Everyday. It’s to create a small dent in the way we learn. And I am so glad to hear that it has helped you. Thanks a ton!
Woah , this builds us as a better learner who actually seeks knowledge than Mark's . This literally is an awsome process to engage everyone in the calss sir .
Mahesh i have watched your videos on khan academy for more than 2 years now and you have been a huge help to me and most likely many others it is because of you i love science today thanks again for being one of the greatest science teacher of this generation!
I think the blunder in your previous explanation is that- the car can't move forward if it doesn't feel any force. Where that force comes from? I think it's the potential energy that was saved while pulling the car backward and it's the cause that the car moves forward and has a kinetic energy. So, the work we had done turned into potential energy. Is it positive work or negative work?
As a teacher, your videos are absolutely amazing for me. I've learnt a lot. And please, make more videos regarding your teaching experiences, since surprisingly there is not a lot of content on youtube which could help teachers improve.
I am glad to hear this feedback. Honestly, I always felt like I didn’t know enough to start telling what other teachers should do. But, somehow thought of giving it a shot. Will do a few. If they are adding value to the community. I will do more. I do have a lot to say based on how I used to teacher before and how my understanding has evolved. Thanks again for encouraging.
@@Mahesh_Shenoy yes, surely eager to know your evolution as a teacher as it immensely helps the teaching community (I am a new teacher, trying to learn). Keep up the great work you do at both Khan Academy and Floathead.
is scored 95 percent just bcoz of u my class 12 thnx a lot u literally let me know the deep concept for each topic....... i mean the real concept.............. thanks a lot for ur efforts make more vidios
Hi Mahesh, I don’t know if it’s just me but the thumbnail to your discussion with 3rd grade students does not show up on my phone. Could you please look into it and maybe also include a link in the description? Thanks for putting up great content about teaching techniques!
Saying Science is not about right or wrong does not sound good at all to me. Science is about searching for the Truth. So whether you're right or not IS extremely important, to the point where we build huge experiments like CERN's LHC just to test whether or not our theories are right. Being wrong oftenly is a consequence of the nature of the whole process and it is not a big deal, is something which you should be used to and will often lead into designing better theoretical models but at the end of the day: In Science we want models which correctly predict something or theories which describe a phenomenon as closely to the truth as we know it (and at School, at a level where the students will understand it, however the models should be as aproximate to the known truth as possible). Another point which I would like to make is that even though putting her on the spot is bad, the best way for her to grow out of it (at least partially, because nobody likes to be wrong in front of an audience even though most of us should be able to tolerate it), is for her to be exposed to situations like such. So maybe it is important for a teacher to ease their students into situations where they are indeed wrong. When they grow up and they are wrong/mess up in their working environment (or even in a University setting), their superiors wont necessarily have the same consideration that you would (and they shouldnt because mistakes can lead to all sorts of problems for clients, company...) Thanks for the video :) I agree when you said that a teacher job is to make their students think and provide them with the tools to validate their thinking/learn. I also loved when you mentioned acknowledging her thinking process and to pull the rest of the students into the discussion which was not something I saw happening too often in my school days.
Don't disagree with you. I think there is a difference between 'being right' and 'getting it right'. The point was, what makes you a scientist is NOT that you KNOW what the right answer (the truth) is. What makes you one is the PROCESS you follow to FIND the truth.
@@Mahesh_Shenoy I recently downloaded insta...one of the first few people that I wanted to follow was you...however din't get yours but got ur wife's :)
negative mass makes this, push negative mass in one direction it accelerates in the opposite direction. May be we do not have negative mass, but we can use the substitution line dark energy, Casimir effect or negative pressure ....
IIT JEE doesn’t really need to learn science. It needs you to learn how to solve specific type of puzzles. That’s why I don’t really like teaching or creating content on that. :/
@@Mahesh_Shenoy Then Can you tell how to tackle those puzzles the intuitive way atleast one proper video where you share everything cause I have seen your videos of approaching JEE ADVANCED questions you are great sir. Please humble request
Does asking the whole class to comment create some amount of putting the student on the spot too? Especially if most of the class falls on one side or the other.
You can mitigate this to some degree using a think-pair-share routine where students can "test" their ideas with their neighbour or neighbours before being asked to share with the whole class.
Haha. I think true learning does require a community and a lot of healthy discussions. Not that that’s happening in the current classrooms anyway. So, you are probably not losing much.
Wait! 😱 It is your voice The man behind the Khan academy video. But the voice have changed recently: I am sure it is no longer you again at Khan academy?
ua-cam.com/video/NkXUsbXorSk/v-deo.html Sir, this is a video from HC Verma in which he explains "Why does current not decrease on passing through a resistance" but when you read some recent comments many people (including me) are talking about heat dissipation by resistor it would be great if you could explain this (or maybe prove him wrong as you have done before). Looking forward to your explanation, even a text one would work
A student in our class had asked this question whose link you're sharing in class. Our Sir(MR Sir) had explained it in this way. That there's not some sink inside the resistor which is going to store the charge. If someone thinks why heat dissipation happens, I think it is because of the energy of colliding (more vigorously due to resistor, the opposition) of electrons. I think this is where the battery comes into play. To ensure more time is not needed by the electrons to traverse the opposition, the battery 'helps' it by giving it more energy/potential. That is why the potential drop occurs across resistance. Feel free to state your opinion on the same. This thing is really intriguing, ever since I first read it in class X!
@@ankitabhaumik8611 Thank you for your response Ankita. "I think this is where the battery comes into play..." i can not understand from here, could you please clarify what you want to say?
@@MrMark-cz3ev I mean I think this is the use of battery. Let's say the time needed for electrons to cross the opposition named resistor was going to be more, but the battery's positive end which is strongly attracting the negative electrons pulls these electrons such that more time is not needed. If time increased current would have decreased. But the battery doesn't allow it to happen, even at the cost of dropping some of its potential at the resistor. Why exactly is the current not decreasing? It might be because of the following reasons- 1. Resistor is not some sink where charge would get stored. 2. Battery is there to attract them to it, even at the expense of loosing some extra work or potential there. I think it is not this extra energy/potential drop of battery which is getting dissipated in the form of heat. Because obviously the potential drop is used for electrons to get more energised such that they can cross even the opposition name to resistor within the stipulated time that is to say without allowing the current to falter. Rather, the heat comes from increased collision and thereby increased kinetic energy of the electrons. But yes, the heat loss might also come a bit from the potential drop of battery. Maybe that is why the heat is VIt. That is it is also dependent on voltage of battery.
