Kisi dost ne mail bhej kar ek baat kahi. Mujhe laga ki shayad kaafi logon ke mann mein same sawaal ho sakta hai, isliye share kar raha hoon.
Sawaal:-
Sir, aapko itni saari cheezon ki knowledge hai, YouTube par bhi aapki achhi-khaasi following hai. Aap padhne ke liye kaunsa method use karte ho? Matlab aapke jaise knowledge kaise gain karein?”
Mera jawab :-
Dost, na to main pehle padhai mein bahut achha tha, na aaj hu. Pehle bhi survival ke liye padh raha tha, aur aaj bhi wahi kar raha hoon.
YouTube par jo dikhta hai, woh hamesha poori reality nahi hoti. Digital duniya perception banati hai. Kisi ko dekh kar hum maan lete hain ki iske paas bahut knowledge hai, bahut paisa hai, bahut perfect life hai — lekin screen ke peeche reality kuch aur bhi ho sakti hai.
Kisi creator ke peeche research team ho sakti hai, script writer ho sakta hai, editor ho sakta hai, ya phir woh khud bahut मेहनत करता हो. Lekin viewer ko sirf final video dikhti hai, poora process nahi.
Isliye meri ek honest advice hai: YouTube ke आधार पर kisi bhi creator ke baare mein blind perception mat banana — mere baare mein bhi nahi.
Meri samajh mein reality simple hai:
Society aapko utni hi value deti hai, jitni value aap society mein add kar sakte ho.
Agar aap knowledge de sakte ho, log aapko sunenge.
Agar aap kisi ki problem solve kar sakte ho, log aapko value denge.
Agar aapke paas koi skill hai, log aapse seekhna chahenge.
Main isliye padhta hoon kyunki mujhe relevant rehna hai. Mujhe apne aap ko update karte rehna hai. Mere survival ke liye mujhe padhna hi padega.
Iska matlab ye nahi ki mujhe har time padhna bahut pasand hai. Iska matlab sirf itna hai ki mere paas aur koi option nahi hai.
Padhne ka sahi tarika?
Meri opinion mein sabse pehle ye find karo ki aap padh kyun rahe ho.
Jitna strong reason hoga, utni hi cheezein samajh aayengi.
Jitna personal reason hoga, utni hi cheezein yaad rahengi.
Padhai ka method baad mein aata hai.
Pehle padhai ka reason clear hona chahiye.

Ek mail aya neeche exact copy paste kar raha hua.
Hello Bhaiya,
I am Ronit Agarwal
Internal forces ki vajah se kisi system mein accleration nahi aata toh agar kisi cheez ke upar khade hoke uspe khade khade ekdum se force lagai jati hai jaise kisi stool ya paidaan pe khade hoke ekdum se force lagaye toh accleration kyu aa jaata hai, ye toh ek he system consider honge aur yaha accleration bhi aa raha hai ye kaise.
Answer :-
Sabse pehli chej "Internal forces COM(centre of mass) ko kabhi accelerate nahi karti.
Ab sawaal ata Kyo nahi karti?
Jawab:- To Imagine karo aap space mai, same stool par khade ho, float kar raho ho,
aapki body aur stool dono ek hi system hai, ab agar aap force lgaoge to aap aur stool dono opposite direction mai move krege { Aapka momentum (upar) = Stool ka momentum (neeche) Net = zero} yani momentum conserve hai. Yani Centre of mass mai koi acceleration nahi hai.
Agla sawal Momentum conserve kyo hota hai?
Jawab :- Newton cha-cha ka 3rd Law = Internal forces hamesha equal-opposite pairs (Joda bna kar aati hai, kabhi akeli nahi) mein aate hain matlab Jab opposite nature ke pair ko add karo toh cancel ho jaate hain yani System par net internal force = zero
Ab force (F) hota hai = mass x acceleration aur kyoki net internal force = zero hai (3rd Law se), to F=ma se acceleration = zero, aur isliye momentum conserved hai.
Newton's 3rd Law → Internal forces cancel (net = 0) → F = 0 → F = ma se a = 0 → velocity constant → momentum conserved
Lekin zameen par jab aap stool ke upar force lagate ho, toh actually stool zameen par bhi force lagata hai, aur zameen external normal force return karti hai — yeh external force hi acceleration produce karta hai." ( newton chacha ka 3 law sare fasad ki jad hai.
umeed hai aapko samjha aa gya hoga.

Kisi bacche ne mail karke ek bda acha sawaal poucha hai.
{Mai personal information ko hide karke exact copy paste kar raha hu}
Question - Dear sir,
I work very hard in my studies and prepare everything thoroughly before going to the exam. But as soon as the questions appear in front of me, I am unable to write the answers properly. Even though I had studied them well, I don’t know what happens during the exam — I just can’t perform as well as I should.
In Physics, I often forget derivations during the exam. I can usually solve numerical problems, but sometimes I get confused with the concepts as well.
Please tell me what could be the solution to this problem and how I can improve my performance in exams?
My Answer -
Mere bhai, problem aapki padhai mai kam aur “retrieval” mai zyada lag rahi hai.
Retrieval ka matlab hota hai — jo information aapke dimag mai already stored hai, exam ke time use sahi tarike se wapas nikaal pana.
Ab iske mainly 2 karan ho sakte hain:
1. Bina deeply samjhe information yaad karna
2. Samajh to aa gaya, lekin usko recall karne ki practice na karna
# 1) Bina samjhe yaad karna
Jab hum sirf ratta maarte hain, to brain information ko exact order mai zyada time tak stable form mai store nahi kar pata. Isliye exam hall mai kuch points yaad aate hain aur kuch achanak blank ho jate hain.
Solution:
Agar bina deep understanding ke exact wording ya derivation yaad rakhni hai, to uska ek hi practical solution hai — regular interval par repetition aur revision.
Yani spaced repetition + baar baar recall practice.
# 2) Samajh aa gaya, lekin recall ki practice nahi hui
Bahut baar hume concept samajh aa jata hai, lekin exam ke pressure mai usko instantly recall nahi kar pate.
Brain usually naye concept ko purani information se connect karke store karta hai. Isi liye jab koi hint ya connection milta hai, to poori information yaad aa jati hai.
Lekin agar exam mai woh hint nahi mila, to recall weak ho sakta hai.
Isliye zaroori hai ki aap khud ke “memory triggers” ya “hints” banao.
Example:
Class 10 Trigonometry mai ek famous line hoti hai:
“Pandit Badri Prasad Har Har Bhole”
Ye ek memory trigger hai jisse initially students trigonometric ratios yaad rakhte hain. Baad mai practice ke saath ye naturally yaad rehne lagta hai.
Physics mai bhi derivations aur concepts ke liye aise shortcuts, flow charts, visual connections aur self-made hints bahut help karte hain.
Aur ek important cheez:
Sirf padhna enough nahi hota. Exam-like conditions mai likh kar practice karna bhi zaroori hai. Kyunki kai baar knowledge hoti hai, lekin brain exam pressure mai usko properly access nahi kar pata.
Ab aapko dekhna hai ki aapki problem mainly understanding ki hai, revision ki hai, ya exam-pressure mai recall weak ho jata hai.

Ek bacche ne mail bheja hai aur physics mai struggle ko lekar kuch baate kahi hai.
{mai mail se personal chje hta kar exact words paste kar raha hu}
Respected sir,
I am a student of class 12th and recently studying in Allen and preparing for IIT JEE but still struggling in physics. ******
******You have said in one of your videos that you are going to start teaching us but yet not sir please understand and start teaching as soon as possible.
My Answer
1) Mai bhi isi system se nikla hu, physics me maine bhi khoob struggle kiya hai.
2) Lekin physics ko samajhne ke liye maine "Reverse Pyramidical" technique use ki, aaj bhi karta hu. ye aapke core concepts ko strong bna deti hai aaur fir physics easy lagti hai, jaise isse jyada intresting aur asan subject doosra koi hai hi nahi.
3) Dekho har insan ke pass koi na koi gift hota hai aapke pass bhi hoga, bas aapko pta karna pdega. Mujhe bhi ek gift mila hai, mai jaise taise problems ko solve kar hi leta hu "ye mera gift hai".
Problem solving ke gift ki wajah se hi mai anjane mai physics ko samjhne ke liye Reverse Pyramidical technique ka use karta tha baad mai mujhe pta lga ki iska ek scientific naam bhi hota hai.
aap bhi apne gift ko khojo, ye aapki growth ko accelerate kar dega.
Gift dhoondne ka tarika ( observe kro aap baki logo se kis chej mai naturally behtar ho, jaha auro ko effort lgane padte hai lekin aap bina effort ke vo same chej kar lete ho) yaha se aapko ye bhi pta chal jayega ki kahi aap galat track par to nahi ho.
4) Rahi baar mere padhane ki to bhiya mera to kaam hi padhane ka hai, aur isi kaam ki wajah se mujhe youtube ke liye 2 din ka samay milta hai, isi do din mai aapke liye video shoot bhi hogi, aur editor bhiya ka mood hua to time se edit bhi hogi, aur publish bhi hogi. Mai youtube par padhane ki koshish me lga hua hu, jaldi hi kuch na kuch productive dikhai dega.

Bharat mein ek jagah hai.
Jahan bimariyon ka ilaj ho sakta hai — jo duniya ki modern medicine abhi dhundh rahi hai.
Diabetes. Autoimmune diseases. Kidney stones. Allergies.
Un sab ka jawab — shayad — ek chhote se island pe hai.
Par agar tum wahan jaoge — toh Maa*e JAOGE.
Seedha. Bina warning ke. Bina reason ke.
Aur sarkar? Sarkar khud wahan jaane se DARTI hai.
Bharat Sarkar ne khud OFFICIALLY declare kiya hai — hum wahan nahi jayenge.
Zameen India ki hai. Hawa India ki hai. Paani India ka hai.
Par wahan ke log — India ka kanoon nahi maante.
Wahan India ka police nahi jaata. Army nahi jaati. Court nahi chalti.
Ek alag hi duniya hai — India ke andar.
Par ye log kaun hain?
ye hai "Sentinelese"

Saurabh ji ne ek mail kiya hai about "corruption in real estate" { mai exact copy paste kar rah hu }
Aapke kya vichar hai iss bare mai jo neeche btaya gya hai? ( sahi hai, koi kami hai ya isme kuch add karna cahate hai)
The Problem
रियल एस्टेट का काला धन कोई छुपी हुई बात नहीं है — यह तो दोनों पक्षों की आपसी सहमति से चलता है। Seller property की कीमत कम दिखाता है ताकि capital gains tax बच जाए। Buyer नकद देता है ताकि अपना बेहिसाब पैसा कहीं लगा सके और stamp duty भी कम भरनी पड़े। दोनों का फायदा है।
The Solution
हर private property की बिक्री को एक government-run public auction portal के through करवाया जाए। जब तक deal उस portal पर नहीं हुई, तब तक sale deed register ही नहीं होगा।
How It Works
Seller अपनी property portal पर list करेगा — photos, details और एक reserve price (जो वो खुद तय करेगा) के साथ। Listing कम से कम एक हफ्ते तक bidding के लिए खुली रहेगी। कोई भी नागरिक KYC verification के बाद register कर सकता है और एक refundable deposit जमा करके bid लगा सकता है। Reserve price से ऊपर की सबसे ऊँची bid जीतेगी। जो winning bid होगी, वही official price मानी जाएगी registration और tax के लिए।
Why Black Money Disappears
Seller अपने किसी जान-पहचान वाले buyer को कम कीमत पर favour नहीं कर पाएगा। अगर वो ऐसा करने की कोशिश करेगा, तो कोई बाहरी व्यक्ति ऊपर से bid लगा देगा — और seller का अपना वो जान-पहचान वाला buyer हाथ से निकल जाएगा। Cash payments का कोई मतलब नहीं रहेगा, क्योंकि deal तो portal पर ही fair market price पर हो चुकी है। कोई बाहरी व्यक्ति seller को bid price से ऊपर extra cash क्यों देगा? उसका तो काम portal पर ही पूरा हो गया।
Impact on Corruption in India
Property रिश्वत और काले धन को पार्क करने की पहली पसंद बन चुकी है। अगर हर sale एक public, digital auction बन जाए, तो यह पूरा channel एक झटके में बंद हो जाएगा। भ्रष्ट अधिकारी नकद रिश्वत लेना इसलिए छोड़ देंगे क्योंकि उस पैसे को छुपाने की जगह ही नहीं बचेगी।आख़िर आदमी अपने घर पर कितना cash रखेगा?
अगर यह विचार आपको सही लगे, तो मेरी विनती है कि आपका platform इसे उन लोगों तक पहुँचाने में मदद करे जो इस पर action ले सकते हैं। जय हिंद। जय भारत।

Saurabh garg
Mr. Saurabh ji has sent an email regarding “Corruption in Real Estate.”
What are your views on the idea presented below?
The Problem
Black money in real estate is no hidden secret — it operates through mutual agreement between both parties. The seller underreports the property value to save capital gains tax. The buyer pays in cash to invest unaccounted money and also reduce stamp duty. Both sides benefit from the arrangement.
The Solution
Every private property sale should be conducted through a government-run public auction portal. Unless the deal is completed through that portal, the sale deed should not be allowed to be registered.
How It Works
The seller would list the property on the portal with photos, details, and a reserve price decided by the seller. The listing would remain open for bidding for at least one week. Any citizen could participate after KYC verification and by depositing a refundable security amount.
The highest bid above the reserve price would win. That winning bid would become the official transaction value for registration and taxation purposes.
Why Black Money Disappears
The seller would no longer be able to secretly favor a known buyer at an artificially low price. If such an attempt is made, another buyer could simply place a higher bid, causing the seller’s preferred buyer to lose the deal.
Cash payments would lose their importance because the transaction would already be completed transparently on the portal at the fair market price. No outsider would have any reason to pay extra cash above the winning bid since the deal would already be finalized officially through the portal.
Impact on Corruption in India
Real estate has become one of the biggest channels for parking bribe money and black wealth. If every sale becomes a transparent digital public auction, this entire channel could be disrupted overnight.
Corrupt officials may stop accepting large cash bribes because there would be no practical way left to hide or invest that unaccounted money. After all, how much cash can someone realistically keep at home?
If you find this idea meaningful, I humbly request your platform to help bring it to the attention of people who can take action on it.
Jai Hind. Jai Bharat.
