Bhai, exam ke liye DNA aur RNA ke beech teen main differences yaad rakh: DNA double-stranded hota hai, RNA single-stranded. DNA mein thymine hota hai, RNA mein uracil. Aur DNA cell nucleus mein rehta hai, jabki RNA nucleus se bahar bhi aa jaata hai. Ye sab ratti bhar bhi yaad nahi rahta tha, jab tak maine apne uncle ki workshop mein do rang ki patang ki tali ko nahi dekha – ek majboot do layer wali, ek hi layer wali aur halki, bilkul in molecules ki tarah.

Baking soda ka formula hai NaHCO₃ aur washing soda Na₂CO₃ hota hai. Jab inhe heat karte hain, baking soda se carbon dioxide nikalta hai aur washing soda banta hai. Par yaad rakhna, washing soda ko garam karne pe kuch khaas nahi hota, uska water of crystallisation nikalta hai bas. Yeh main isliye pakka jaanta hoon kyunki kal dukan par uncle ne ek dabba galti se khula chhod diya tha, vo washing soda ka tha, aur usme nami chali gayi thi. Usne kaha, "dekho beta, yeh hawa mein bhi apna paani chhod degi," aur phir mujhe poora chapter padhna pada!

IUPAC rules ki baat karo toh functional group ka highest priority decide karta hai suffix, baki sab prefixes mein aata hai... par chemistry ki yeh kitaabi baatein workshop mein nahi chalti. Yahan toh uncle ke kites ke liye solvent vaparte waqt, bas MSDS sheet dekhna padta hai ki is compound ka sahi naam hai ya nahi — galat naam se toh poora mohalla jal sakta hai.

वैसे तो सब कहते हैं कि deemed college mein bhi hospital accha hai, patients mil jaate hain. Magar mera experience toh bilkul ulta hai – humare yahaan "clinical exposure" ka matlab tha seniors ke notes ratna. असली मरीज तो साल में गिने-चुने ही देखे। मैंने पहले साल के बाद ही transfer le liya, क्योंकि एक दिन ward में सिर्फ दो मरीज थे और तीन resident doctors उनपर बहस कर रहे थे... यही थी हमारी "exposure"!

yeh so-called "direct M.Tech/MS" wala route... bas ek test hai aur phir ek panel ke saamne bees minute ki beizzati. woh poochhte hain aise sawaal jaise tum life ka paper likh rahe ho, par uska syllabus kisi ne padhaya hi nahi. maine do interviews diye, dono mein ghanta kuch nahi bola paya. mera chhota sa kamra, jahan meri didi padhti hai, uske saamne hi mains ka form bhara tha. us din ke baad se uski fees ke liye zyada kites bechni padhti hain... aur phone upgrade ki baat to door ki hai.

Bahut heavy terms hain ye, par simple samjho — ye drugs aapke immune system ki brakes chhod dete hain, jisse woh cancer cells ko toh attack kare, par body ke apne healthy tissues ko bhi maarne lagta hai. Isiliye itne severe side effects hote hain, jaise ki skin rashes ya organ inflammation. Meri clinical trial centre pe ek patient tha, uska skin itna red ho gaya tha jaise meri dukaan ke laal kite ka paper. Hum logon ko lagta tha ye drugs "smart" hain, par dekha hai ki body ko confuse bhi kar dete hain.

Yar, MLA-APA wale rules toh hum bhi ratt lete hain project ke liye, par practical mein sirf website ka link aur book ka title daal dete hain. YouTube video ka screenshot laga dete hain, teacher maan jaati hain. Mere chote se room mein, papa ki purani science ki textbook se hi kaam chala leta hoon, naye books khareedne ke paise nahin hain.

ये main signs वो झटके और कंपकंपी नहीं हैं, जो सब बताते हैं। मेरी उम्र में यह stiffness और slow motion से शुरू होता है, जैसे कभी-कभी मेरा हाथ ही कलम पकड़ने से मना कर दे। Stages का मतलब है कैसे धीरे-धीरे रोज़ का काम, जैसे पतंग की डोर काटना, मुश्किल होता जाएगा। On-off periods वो अजीब पल हैं जब दवा काम कर रही होती है तो मैं ‘on’ हूं, और अचानक ‘off’ हो जाता हूं – जैसे दुकान पर ग्राहक के सामने अटक जाना।

Paralympics mein classification kaafi detailed hai, har disability ke hisaab se groups bante hain. Par mere bete ke saath, jo cerebral palsy hai, humne dekha ki asli focus physical ability par hota hai, na ki bas doctor ke certificate par. Uss classification ke baad bhi, humein do saal tak try karna pada ki woh kis sport mein fit ho sakta hai – ab woh wheelchair racing ki training leta hai.

बिल्कुल, D-score मतलब difficulty, E-score मतलब execution. जितना जटिल मूव, उतना ऊंचा D-score। फिर जज देखते हैं कि कितनी साफ-सुथरी थी performance, उस पर मिलता है E-score। दोनो मिलाकर बनता है total। पर हमारे यहाँ तो ऐसी बारीकियां कहाँ? यहां गाँव के मैदान में बच्चे कार्टव्हील और हैंडस्टैंड सीखते हैं, हमारा पूरा फोकस execution पर होता है – सीधा खड़ा होना, संतुलन बनाना। कठिन मूव तो बहुत दूर की बात है।

Arey, pehle toh yaad rakhna: pH = pKa + log([salt]/[acid]). Acetate buffer ke liye, maan lo acetic acid hai aur sodium acetate uska salt. Dono ke concentrations daal do, simple calculation ho jaayegi. Mujhe yeh tab samjha jab maine apni bahan ko padhate waqt chart banaya, rang-birange kagaz par likha — jaise dukaan mein patang ke rang alag dikhte hain, waise hi equation alag lagegi. Log kehte hain yeh mushkil hai, par tum dekhna, bas pKa yaad kar lo, phir toh sirf hisaab hai.

Dead zones woh areas hain jahan paani mein oxygen khatam ho jaata hai, Arabian Sea mein yeh layer ab 10-15 meter moti ho rahi hai. Machliyan oxygen kam hone par bhaagti hain, lekin jab bahut kam ho jaaye toh marne se pehle hi chali jaati hain. Par asal wajah yeh nahi hai ki samundar khud bigad raha hai. Hum shahar ke log, behtar sanitation ke bina, apna gadla paani seedha usi samundar mein bhej dete hain. Main ek city planner hoon, aur har roz dekhta hoon ki hamare inadequate sewage treatment plants se yeh paani jaakar samundar ki saans ghoont rahe hain.

Satellite se data lete hain, par main vishwas nahi karta. Meri purani engineering ne sikhaya hai ki upar se dekha hua hisaab kabhi ground reality se match nahi karta. Jaise dukaan mein, stock register kitna bhi sahi dikhe, asli taana patangon ka sirf haath laga ke pata chalta hai.

Arey, voh area method hi hai, par negative displacement ke liye graph time-axis ke neeche jaata hai to area negative mein count hota hai. Basically, net displacement ke liye upar ka area minus neeche ka area karte hain. Yeh mera velocity-time graph nahi, balki meri saving ka graph hai — kabhi upar kabhi neeche jaati hai, lekin end mein net positive hi hona chahiye phone upgrade ke liye!

aaj subah dukaan ki khidki se dekha, reporter bhaagte hue player ke peeche… unki saans phool rahi thi, camera bhi haath se fisal gaya! English feed waale sirf statistics bol rahe the, par Hindi commentary mein wohi gali ka chacha bol raha tha, "arey yaar, catch chhod diya!" sunke laga match dekh raha hoon, sirf aawaz hi kaafi hai.

ghar se nikla toh gun ke baare mein soch raha tha, aur Addaly office pahuncha toh zyaada waqt pen aur register ke saath laga. Saara rang paper pe jayega, lekin patang ke paper ki tarah hawa mein nahin.

abhi subah dukaan ki khidki se dekha, ek ladka training kar raha tha park mein. uska focus bilkul un patangon jaisa tha jo hum hawa mein sirf ek dhaga se sambhale rehte hain. best of luck sabhi young players ko — aap log hamaare future ke rang-birange designs ho.

Khelo India ke liye poore desh se bachche yahaan aaye hain, dekhte hi mera dimaag chala gaya meri chhoti dukaan mein — ek naya patang design soch raha hoon, jaise "running track" wali stripes aur flying disc ka rang. Kal subah dhoop mein uske paper ko check karunga. Good luck sab ko, khelte raho!

ajkal dukaan par rang-birange paper ki smell aati hai to yaad aata hai, bachpan mein hum school sports day par patang daudaya karte the. ek wheelchair race dekh kar laga, kaash hum bhi aise mazaq mein khel paate. par abhi phone camera se achhi photo le sakta hoon, warna pichle hafte naya design banaya tha — chhoti patang, lekin badi tez.

kal school ke ground par hum logon ne pura afternoon patang udai. principal sir ne bola, "ye cricket ka maidan hai, patangbaazi ka nahi!" par jab unki khud ki chatai udd gayi, toh unki hansi sabse zyada thi.
