I don’t know why YT showed me this video. After watching this and after checking the confidence of this person let me add something. Tell me one situation where current follows vector laws. You will not find a single situation. While calculating magnetic field we don’t take current as vector we take “current element” where we associate small element “dL” which has direction not the current. Similarly in current density we take projected area which is perpendicular to direction of current so that projected area makes it vector not the current. Also you can treat it like charge density times velocity,here velocity is a vector. In AC calculation we add two currents as a vector but in AC it is not a vector it is a sinusoidal quantity which has some phase and frequency and if we add two different sinusoids with same frequency and different phases then we are actually adding their instantaneous values and it follows phasor concepts not the vector concepts. You can say that two sinusoids of same frequency but different phases can be added with the help of phasors and it is similar to vector addition. We are actually adding two sinusoids of same frequency to get a new sinusoid. Tell me one situation where we take current as a vector. You will find none. Moreover it is not like “jaroorat k hisaab se define krtey hn…”everything in physics have meaning and significance. Let me tell you one more point VerySmall angular displacement can be treated as a vector coz it follows vector rules (standard) while the large or finite angular displacement can not be taken as vector coz it violates the basic rules of vectors. So it’s not like” jaroorat k hisaab se define krtey hn” there are standard rules which must be followed by vectors. For deeper understanding read “The Feynman lectures on Physics volume-2”chapter-2 section 2and 3 Volume-1 Chapter-11. From where this confusion came from? When we add current in AC sinusoids (same frequency with different phases) then we can add them by taking it like a vector whose magnitude is max value and phase as angle. Now one more request in this video he is showing that he knows more than others please take a pause and calm down.
Current is a scalar as it measures the net charge flow rate through a cross-section, direction-independent. Current density is a vector as it describes the magnitude and direction of charge flow at each point, essential for modeling current distributions and applying Maxwell’s equations in electromagnetism
I don't know why he is just saying crazy things, no derivations, no proof Here are some popular physics and electronics books that support the answer: 1. "Halliday, Resnick, and Walker's Fundamentals of Physics" (10th edition) - Chapter 28: Electric Current 2.

"Giancoli's Physics for Scientists and Engineers" (4th edition) - Chapter 25: Electric Current and Resistance 4. "Kirkpatrick and Wheeler's Physics: A World View" (8th edition) - Chapter 24: Electric Current 5. "Nilsson and Riedel's Electric Circuits" (10th edition) - Chapter 1: Introduction to Electric Circuits In these books, you'll find that electric current is treated as a scalar quantity, with only magnitude (amperes, A) and no direction. However, the direction of current flow is often indicated in circuit diagrams and discussions. Additionally, you can also refer to: - "The Feynman Lectures on Physics" (Volume 2) by Richard Feynman - Chapter 23: Electric Current - "Electricity and Magnetism" by Edward M. Purcell - Chapter 1: Electric Current These books provide a more in-depth understanding of electric current and its behavior, reinforcing the concept of current as a scalar quantity.
Current is a scalar beacuse it is defined as charge passing THROUGH A PARTICULAR CROSS SECTION IN A GIVEN TIME PERIOD. So CURRENT HAVING DIRECTION DOESN'T MAKE ANY SENSE. Current density , however, has a direction as it is defined at a particular point (in di/dA, area tends to zero) so it is always a vector. PLEASE REFER TO PROF. HC VERMA'S VIDEO ON THE SAME TOPIC.
Current is scalar becoz of conservation of charge. That is charge flowing towards a point is always equal to charge leaving the point. It doesn't depend on the direction in which charge is flowing.

You are right. Theoretically the statement is correct a & and of course it can be validated practically..it is well understood, that current is basically flow of charge and resultant of 3 & 4 amp at 90 deg will give results of 5 ampere but total charge was 7 originally. Where has remaining 2 unit of charge gone? ....so it will not disappear any where because charge is conserved and therefore it is not vector quantity as it does not follow vector law of triangle addition
The question could be framed in a more intriguing way: Why is current considered a scalar even though current density is a vector quantity? Additionally, current is never treated as a vector in electromagnetism. In Lorentz's law, the velocity of a charge is considered a vector, and the length of a wire is also treated as a vector. However, current is always considered a scalar.
Mr. Galat Pandey was once teaching "centrifugal force balances centripetal force" i tried to correct him in comments and the students abused me the comment section They even said, hum to galat padhenge lekin sir ke khilaf nahi sunenge Teacher fan following is the biggest road block in a students selection
@itishreepanda1641 hindustan jante ho peeche kyu hai. Kyunki yaha har chaman ke bhakt zaruri mil jaenge Ab jo aadmi ohms law ko V proportional to I bataega uske bhi bhakt h. Sahi h
That one teacher who says 'mere method se nhi kiya beta to galat hai' He needs to keep his ego aside for such kind of videos. Such type of videos are appropriated but ego that he carries that only his method of explaining something is the only method is not good for any teacher. The point he made that teachers explain current ki vo tensor quantity hai, i agree to this because there is a lot of confusion among teachers that tensors are third type of quantity along with scalar and vector. But i disagree with the fact that he thinks explaining that current is scalar by stating it does not follow vector law is wrong. As anything can be disproved using various methods. Their are plenty of reasons that current is not a vector, and not following vector laws is one of them. Students at 11 and 12th level will not get all the tensor stuff, so they are given the simplest reason. He himself rant for 10 minutes without explaining why the statement "current do not follows vector laws so they are scalar" is wrong because there is nothing wrong with the statement. It is just one way you can explain why current is scalar their are several other ways. I respect the kind of series of videos, but keep the ego aside that will make you the only thing you are going against. Their is no place of ego in physics. Even the greatest mind of all time disagree, but they learn from the discussion and move.Peace ✌️
@SufiyanOp-eg4if I missed the point where he says that current density does not obey vector laws. It does obey vector laws, but in most cases, we do not need to add current densities. We use equation of continuity in most of the cases. If u r at 12th level, u might not understand, but the divergence of current density is the rate of change of charge density. Dot product of current density with surface element gives electric current(Mathematically current is scalar too).

Sir jii aapne jo likha j=I/A wo vector hai nai kyu ki vector ki division defined nai hai Agar koi cheez vector hai toh usko vector addition ke rules follow karne chaiye Haan ye baat hai ki current ki direction zaroori nai isliye hum usko vector nai bolte Aur rahi baat tensor ki toh moment of inertia ko hum plus two level tak scalar hin bolte hai lekin baad me wo rank two tensor ke hisab se act hoti hai To current tensor hai ye confusion wahan se create hua hoga
Not True. Current as shown in wires and circuit has one degree of freedom as it can travels only along the length of the wire , hence scalar so direction is not important. Even in the case of Biot Savarts law the direction of velocity of electron is taken into account rather than the direction of current. Velocity is vector, Current along a wire isn't.
Some men, change your perspective about life forever. It never matters where they come from, what matters is the mark they leave.

@aravshah1644 Video ka point ye hai ki Jahan ,hamein kisi phenomenon ko predict karne ke liye kisi physical quantity ki disha ki bhi jarurat hoti hai use vector kehte hain aur jahan zarurat nahi hoti wahan use vector nahi kehte .

Regarding area ,it is not like we choose whether there is direction or not , to define an area properly the orientation of area is important, that means to define area completely it is not a choice but a compulsion to have a direction,so it is a vector and current doesn't have direction but have a sense
Shiksha is ⚖️ 📐 📏 ⚖️ scalers quantity and diksha is directed so its quantity vectors which have both directed in positive direction with right ✅️ decision
After seeing your catchy thumbnail, I decided to watch the video carefully. After viewing the entire video, I tried to identify any misconceptions or new concepts you introduced, but I found none. I'm also puzzled by your claim that 98% of students misunderstand this concept (I'm curious about your source for this data 😝. Proper references and justification are needed if possible). The diagram you drew on your digital board illustrating current addition in branches is based on Kirchhoff's Current Law (KCL). Current always follows this law. It's a well-established principle in physics, which uses scalar algebra, not vector algebra. Therefore, if asked why current isn't considered a vector, one can argue that since current doesn't follow vector addition, it isn't a vector. This explanation is accurate, so I'm not sure why you claimed it's incorrect.
@@serviceuser6066 You are absolutely right. In the name of IIT, they are doing anything which is not relevant. I don't know where he learned this rubbish thing "zaroorat ke hisab se physics main jo chaho woh kar sakteho...". Total rubbish..

I am going to persue integrated phd in astronomy from TIFR and i had this doubt since class 12 that why current density is a vector quantity coz even that doesn't follow the laws of vector addition. After 5 years, my doubt has been ckeared lmao. Kash humare time me bhi ese teachers padhate online
It is indeed deeply saddening to see the PhD candidate with unclear concepts being selected in a top research institute like TIFR. As for the explanation, it is very simple and doesn't demand a video. J vector= I/ A vector ( has both mag. and direction). Similarly, J=σ E where E is a vector and in J= ρv ρ= charge density and v= drift velocity of charge carriers. This makes J a vector. And as you know, vectors, scalars and dimensionless quantities all come under tensor matrices, just the orders are different. Thank you.
Another analogy though unrelated. Despite having direction and magnitude, angular displacement is not a vector because it does not obey the commutative law for addition. But when dealing with infinitesimal rotations, second order infinitesimals can be discarded and in this case commutative property appears. The direction of angular displacement is different from that of linear displacement for two reasons. First, it points out of the plane because of the nature of angular displacement. It signifies a rotation, as such, there is not any particular direction unit vector in every coordinate space that could represent it. To signify the direction of something that points in every direction on a plane, it is easy to specify it along the one direction we can be sure the linear displacement isn't pointing normal to the plane. This is a much used convention (such as with area vectors, torque, and many others). As usual as well, we use the Right Hand Rule. The second, and perhaps more important reason is that we always want to ensure that the angular displacement does not correspond to any true displacement that would be in a radial direction. Sorry for copying, I was too lazy to type.
Let assume r=5 unit, then rcostheta =4 and rsintheta=3, rsintheta ka liya dipole ki perpendicular bisector hoga but rcostheta ka liya dipole er axis barabar electric field aayaga but dono point alag hay. So it is not a suitable process of finding electric field.
1. Electromagnetic Theory: In Maxwell's equations, which form the foundation of classical electromagnetism, current density ( 𝐽 J) is a vector quantity because it describes the current per unit area flowing in a specific direction. However, the total current (I) is the integral of the current density over a cross-sectional area: 𝐼=∫𝐽⋅𝑑𝐴 limits A Here, the dot product 𝐽⋅𝑑𝐴 J⋅dA results in a scalar because it represents the net charge flow through the area 𝐴 A. This integral sums the contributions from all infinitesimal area elements to yield a single scalar value for current.😅

I think we can't consider 3/a and 7/a directly. If the area is identical then same value current should flow through the wire which is 5/a and 5/a. And for current density we have to consider angle between current and area vector at this location not overall conductor, or wire bent location.

I really love the way you explained... But I am really sorry ... I still didn't understand the reason of current being the scalar quantity. If you have to define perfectly the scalar or vector quantity how will you define ? Is the definition of b answer is wrong ? Its not about just proving others wrong but I need a solid reason to call you as right.🙏 I hope you won't take this comment to be negative. Thank you.
Never seen a single teacher who ever said esa hi hota hai except school teacher. Current flows in the opposite direction of electron flow, direction to idhar bhi define ki gayi hai, to m isse kya maanu? Scalar ya vector? Ya fir yahi bolta rahu ki experiment krke batunga kya hai? Ab yahan pe nahi bolu kya ki current ki direction ko pehle define kr diya tha or ye baad m pata chala tha ki charge (electron) ki opposite direction m hai?
Examples of tensor quantities include stress and strain. Current cannot be classified as a tensor quantity because it has only one component (magnitude) and does not transform under a coordinate transformation.👉sir abb boliye
Those are tesor of rank two required 2 direction and having nine components. Vector needs one direction has 3 components. If we need n directions than its rank will be n and it will have 3 to power n
Actually, before the discovery of electrons, it was believed that current is the flow of positive charges and so theorems were made on that basis. After the discovery of electrons and that they are the reason for current.. Their directions were taken opposite to that of conventional as it is negative.. Hence conventional currents are taken positive
Writer vector nasa, u will get a nasa page which defines vector It clearly says vectors are those quantities which requires the information of direction to specify them and scalars are those which do not require information of direction to specify them Unfortunately all Indians books define it wrongly
Sir, pls clear doubts regarding using sign conventions twice in the mirror and lens and using once in deriving lens makers formula. I have read all the answers, available on the internet, but not convinced completely. Please take this doubt in your next vdo 🙏
You are using lens and mirror formula both are same for convex as well as for concave so to again using sign conventions you can differentiate the two.. Other it's not possible to check wether it is convex or concave
Read it carefully before dancing for debate !!!!! If you take any reputed book then it is clear already. They don't just say only about magnitude and direction but they mention about line of support or they use the word meaningful direction. Most of the students say it doesn't follow law of vector addition ( by keeping intuition about meaningless direction ) . I respect your way of explanation but the way you are trolling other physics teacher may be a little bit polite. Yes, they shouldn't use it as a trick or tactics by dancing 😂.agree
I know current is tensor quantity but I was told in BTech 3rd year ....nothing earthquake I felt when I didn't know during my jee preparation....koi phad nhi toot pdeyga....ye jaaney sey ki tensor quantity sey.....even... line man don't know nothing about transformer still he can maintain better then engineer...so knowing fancy terminology doesn't make much difference 😕😕

Sir, I heard you are an IIT graduate. And you don't know vector clearly! Surprising! For school student we can define vector as quantity having magnitude, direction, & obeying vector law of addition. There are many quantities having magnitude & (sense of) direction, but not obeying vector law of addition. They are not vector at all. Please note 'obeying vector law of addition' is a necessary condition for a quantity to be a vector. Unfortunately, many (low level, non-rigorous) books do not state but tacitly assume this. For BSc student we can define vector more strictly like this: Vector is a combination of 3 quantities that transform when the coordinate axes rotate according to a definite law. Sir, please read a good book on tensor. You don't know the motivation behind the definition of vector. Once you know it, you will feel embarrassed trolling on those 98% you said wrong. You also seems not knowing the full significance of current density vector. Current density 'j' obeys vector addition law because it works for differential form, but (dc) current 'i' doesn't because it is for integral form. How!? I hope you'd enjoy thinking over this! Many errors in your conceptual understanding! I pick up only two. I ponder over why such errors! I think this is because entrance & board exam never ask deep question on concept, but only definition &/or application type questions. PS: I appreciate your attitude of 'not taking anything for granted' but deplore your trolling nature & overconfidence in your understanding.
This time NMS sir has indirectly targeted Alakh Pandey😂😂 Alakh pandey in his 1st video of current electricity taught that current is not a vector because it doesn't follow law of vector addition.

Moreover it is not like “jaroorat k hisaab se define krtey hn…”everything in physics have meaning and significance.
Let me tell you one more point
VerySmall angular displacement can be treated as a vector coz it follows vector rules (standard) while the large or finite angular displacement can not be taken as vector coz it violates the basic rules of vectors.
So it’s not like” jaroorat k hisaab se define krtey hn” there are standard rules which must be followed by vectors.
For deeper understanding read
“The Feynman lectures on Physics volume-2”chapter-2 section 2and 3
Volume-1 Chapter-11.
From where this confusion came from?
When we add current in AC sinusoids (same frequency with different phases) then we can add them by taking it like a vector whose magnitude is max value and phase as angle.

Mr. Galat Pandey was once teaching "centrifugal force balances centripetal force" i tried to correct him in comments and the students abused me the comment section
They even said, hum to galat padhenge lekin sir ke khilaf nahi sunenge

That one teacher who says 'mere method se nhi kiya beta to galat hai'
He needs to keep his ego aside for such kind of videos. Such type of videos are appropriated but ego that he carries that only his method of explaining something is the only method is not good for any teacher.
The point he made that teachers explain current ki vo tensor quantity hai, i agree to this because there is a lot of confusion among teachers that tensors are third type of quantity along with scalar and vector.
But i disagree with the fact that he thinks explaining that current is scalar by stating it does not follow vector law is wrong. As anything can be disproved using various methods. Their are plenty of reasons that current is not a vector, and not following vector laws is one of them. Students at 11 and 12th level will not get all the tensor stuff, so they are given the simplest reason.
He himself rant for 10 minutes without explaining why the statement "current do not follows vector laws so they are scalar" is wrong because there is nothing wrong with the statement. It is just one way you can explain why current is scalar their are several other ways.
I respect the kind of series of videos, but keep the ego aside that will make you the only thing you are going against. Their is no place of ego in physics. Even the greatest mind of all time disagree, but they learn from the discussion and move.Peace ✌️
But sir also gave the example that even current density doesn't follow vector addition but it is a vector quantity🤔
@SufiyanOp-eg4if I missed the point where he says that current density does not obey vector laws. It does obey vector laws, but in most cases, we do not need to add current densities. We use equation of continuity in most of the cases. If u r at 12th level, u might not understand, but the divergence of current density is the rate of change of charge density. Dot product of current density with surface element gives electric current(Mathematically current is scalar too).
Sir can you pls explain me why in case of EF due to dipole at any theta we cant resolve the distance between the pt. And dipole into its rectangular components ?
Resolve kr ke kroge kya.. Resolve kr ke axial and equitorial par field aa jayega. Jo apko phle se pta tha. Resolve use kro jisko kr ke kaam easily ho jaye,

U got fooled sir
Sir jii aapne jo likha j=I/A wo vector hai nai kyu ki vector ki division defined nai hai
Agar koi cheez vector hai toh usko vector addition ke rules follow karne chaiye
Haan ye baat hai ki current ki direction zaroori nai isliye hum usko vector nai bolte
Aur rahi baat tensor ki toh moment of inertia ko hum plus two level tak scalar hin bolte hai lekin baad me wo rank two tensor ke hisab se act hoti hai
To current tensor hai ye confusion wahan se create hua hoga
Ek aur baat jo current ka direction hum bolte hai jo dl ban jata magnetic field me wo actually electrons ke velocity ka direction hota hai

Not True. Current as shown in wires and circuit has one degree of freedom as it can travels only along the length of the wire , hence scalar so direction is not important. Even in the case of Biot Savarts law the direction of velocity of electron is taken into account rather than the direction of current. Velocity is vector, Current along a wire isn't.

Regarding area ,it is not like we choose whether there is direction or not , to define an area properly the orientation of area is important, that means to define area completely it is not a choice but a compulsion to have a direction,so it is a vector and current doesn't have direction but have a sense
Very informative video sir thank you so much ❤❤❤🎉
Shiksha is ⚖️ 📐 📏 ⚖️ scalers quantity and diksha is directed so its quantity vectors which have both directed in positive direction with right ✅️ decision
After seeing your catchy thumbnail, I decided to watch the video carefully. After viewing the entire video, I tried to identify any misconceptions or new concepts you introduced, but I found none. I'm also puzzled by your claim that 98% of students misunderstand this concept (I'm curious about your source for this data 😝. Proper references and justification are needed if possible).
The diagram you drew on your digital board illustrating current addition in branches is based on Kirchhoff's Current Law (KCL). Current always follows this law. It's a well-established principle in physics, which uses scalar algebra, not vector algebra. Therefore, if asked why current isn't considered a vector, one can argue that since current doesn't follow vector addition, it isn't a vector. This explanation is accurate, so I'm not sure why you claimed it's incorrect.
Actually sir is misleading.. to get views.. Do really students in class 12th needs to learn the relativistic concepts...
@@serviceuser6066 You are absolutely right. In the name of IIT, they are doing anything which is not relevant. I don't know where he learned this rubbish thing "zaroorat ke hisab se physics main jo chaho woh kar sakteho...". Total rubbish..

Sir aap ne kaun si neyi baat bol di ghuma fira ke wahi boldiya sir aapne. I agree u explained in a better way in a good clarity.
I am going to persue integrated phd in astronomy from TIFR and i had this doubt since class 12 that why current density is a vector quantity coz even that doesn't follow the laws of vector addition. After 5 years, my doubt has been ckeared lmao. Kash humare time me bhi ese teachers padhate online
Please read physics again, who said current density don't follow law of vector addition, it follows all laws of vector
It is indeed deeply saddening to see the PhD candidate with unclear concepts being selected in a top research institute like TIFR.
As for the explanation, it is very simple and doesn't demand a video.
J vector= I/ A vector ( has both mag. and direction).
Similarly, J=σ E where E is a vector and in J= ρv
ρ= charge density and v= drift velocity of charge carriers.
This makes J a vector.
And as you know, vectors, scalars and dimensionless quantities all come under tensor matrices, just the orders are different.
Thank you.
Another analogy though unrelated. Despite having direction and magnitude, angular displacement is not a vector because it does not obey the commutative law for addition. But when dealing with infinitesimal rotations, second order infinitesimals can be discarded and in this case commutative property appears.
The direction of angular displacement is different from that of linear displacement for two reasons. First, it points out of the plane because of the nature of angular displacement. It signifies a rotation, as such, there is not any particular direction unit vector in every coordinate space that could represent it. To signify the direction of something that points in every direction on a plane, it is easy to specify it along the one direction we can be sure the linear displacement isn't pointing normal to the plane. This is a much used convention (such as with area vectors, torque, and many others). As usual as well, we use the Right Hand Rule.
The second, and perhaps more important reason is that we always want to ensure that the angular displacement does not correspond to any true displacement that would be in a radial direction.
Sorry for copying, I was too lazy to type.
Guruji ye to batao ku hum r ka component na lekar dipole ka lete hai ???🙏🏻
Let assume r=5 unit, then rcostheta =4 and rsintheta=3, rsintheta ka liya dipole ki perpendicular bisector hoga but rcostheta ka liya dipole er axis barabar electric field aayaga but dono point alag hay. So it is not a suitable process of finding electric field.
1. Electromagnetic Theory:
In Maxwell's equations, which form the foundation of classical electromagnetism, current density (
𝐽
J) is a vector quantity because it describes the current per unit area flowing in a specific direction. However, the total current (I) is the integral of the current density over a cross-sectional area:
𝐼=∫𝐽⋅𝑑𝐴 limits A
Here, the dot product
𝐽⋅𝑑𝐴
J⋅dA results in a scalar because it represents the net charge flow through the area
𝐴
A. This integral sums the contributions from all infinitesimal area elements to yield a single scalar value for current.😅

Baaki toh sir this series is extremely helful (concepts fir se click hothe dimaag me)
I think we can't consider 3/a and 7/a directly. If the area is identical then same value current should flow through the wire which is 5/a and 5/a.
And for current density we have to consider angle between current and area vector at this location not overall conductor, or wire bent location.
True, yh sir ne bhi pura complete nhi btaya

Ab yahan pe nahi bolu kya ki current ki direction ko pehle define kr diya tha or ye baad m pata chala tha ki charge (electron) ki opposite direction m hai?

Examples of tensor quantities include stress and strain. Current cannot be classified as a tensor quantity because it has only one component (magnitude) and does not transform under a coordinate transformation.👉sir abb boliye
Those are tesor of rank two required 2 direction and having nine components.
Vector needs one direction has 3 components.
If we need n directions than its rank will be n and it will have 3 to power n
@@ISACSnf okay 👍 sir
Sir i am a class 10th student . Sir can you answer my question that why is the conventional direction of current is positive?????
Actually, before the discovery of electrons, it was believed that current is the flow of positive charges and so theorems were made on that basis. After the discovery of electrons and that they are the reason for current.. Their directions were taken opposite to that of conventional as it is negative.. Hence conventional currents are taken positive

What about time then?It is continously moving from past to future since the universe came into existence.It has a spatial direction.
Read it carefully before dancing for debate !!!!!
If you take any reputed book then it is clear already. They don't just say only about magnitude and direction but they mention about line of support or they use the word meaningful direction.
Most of the students say it doesn't follow law of vector addition ( by keeping intuition about meaningless direction ) .

Sir, I heard you are an IIT graduate. And you don't know vector clearly! Surprising! For school student we can define vector as quantity having magnitude, direction, & obeying vector law of addition. There are many quantities having magnitude & (sense of) direction, but not obeying vector law of addition. They are not vector at all. Please note 'obeying vector law of addition' is a necessary condition for a quantity to be a vector. Unfortunately, many (low level, non-rigorous) books do not state but tacitly assume this. For BSc student we can define vector more strictly like this: Vector is a combination of 3 quantities that transform when the coordinate axes rotate according to a definite law. Sir, please read a good book on tensor. You don't know the motivation behind the definition of vector. Once you know it, you will feel embarrassed trolling on those 98% you said wrong. You also seems not knowing the full significance of current density vector. Current density 'j' obeys vector addition law because it works for differential form, but (dc) current 'i' doesn't because it is for integral form. How!? I hope you'd enjoy thinking over this! Many errors in your conceptual understanding! I pick up only two. I ponder over why such errors! I think this is because entrance & board exam never ask deep question on concept, but only definition &/or application type questions.
PS: I appreciate your attitude of 'not taking anything for granted' but deplore your trolling nature & overconfidence in your understanding.
