Review of 1st paper-Elementary Particle Physics


Well well~~ Elementary Particle Physics is overr~~So ni review:

Soalan [1] pasal derive Klein-Gordon equation then limit dier. Yang ni mcm yakin okey la pastu dier mintah Dirac's equation..ok ini mmg blur2x hwa hwa hwa tulis je apa yg ingttt (-.-) pastu dier mintk explain Feyman diagram about QuantumElectroDynamics (QED).K macam boley makan soklan neh.pastu dier suruh bezakan classical and relativistic particle..ni ingat suam2 kuku. tapi citer gak la pasal de broglie wavelength and last dier suh carik de broglie wavelength. so rasa mcm ada kena mengena soklan dua nieh.

Soalan [2]. By using conservation of laws, determine weather these reaction is possible.Dier kasi 6 reactions. ok semua impossible except one reaction. at first, aite suma reaction tak impossible???????ragu2 gak la tp yakin kan diri haha
And then distinguish between real and virtual particles k ni soklan boleh makan punye then dier kasi 6 lagi reaction untuk check possibility dgn gunakan strangeness. boleh la makan. then last dier minta unique features in weak interaction.k ini ...ini... waaaa separuh je ingatttttt takpe2 dah lepasss

then soklan [3] agak psycho. first dier mintak explain quark model and the mcmana quark can overcome the violation of Pauli's exclusion principle hehehhee ini soklan feverettt hehehe and then define quark confinement ngan asymptotic freedom ok ini boleh makan siket then soalan killleerrr:

How do we explain the co-existance of above conflicting concepts for quark and gluon?


................................................k takda idea...jadi kena la mencarut kat jawapan..seyes tak pasti jawapan betul ke tak tp goreng2 pasal gluon la hopefully dapat markah siket.
lepas tuh dier mintak lukis beta decay nyer feynman diagram fuuuhhh naseb baek tgk gakkk benda niehhh and last dier tnya pasal Deep Inelastic Scattering..k ini punya jawappan pendek je tp markah kt tepi 20 markah...tak tau la cukup ke tak

So overall, pilih soklan [1], [2], and [3]. ok kenapa tak pilih soklan [4] dan [5]?
soklan 4 mmg seksa giler. dier suh explain pasal solar neutrinos--> SEYES TAK BACA LANGSUNG! but neutrino oscillation and string theory ada baca tp tak leh la nk risk kat situ

soklan 5, 1st dier suh classify baryon and meson octet. k ini aku boleh jawab, konpim. then dier mintak explain generation of quark, lepton and force carrier. k ini konpim boleh jawap. then dier tnya gauge invariance, ni pun boleh jawab. tp..tp...tp soklan last ni pengiraan dlm tutorial and tak ingat langsunngggg! and dier bwk 30 markah.
mmg agak berbelah bahagi la sama ada jawap soklan 1 atau 5. if amik soklan 5 kena risk 30 markah sbb tak tau. tp soklan 1 at least stp jawapan ada markah siket. so decided amik soklan 1. final exam tak leh risk markah even siket pun.

and then last class td kitaorang kasik cenderahati kat Prof Jojo..sedey plak klas dah habis..inilah satu-satunya klas sem ni yg tak pernah ponteng kecuali masa observation hari tuh. the best lecturer I've ever met. serious, klas ni belajar bukan pasal exam tp pasal ilmu...sayangnya tak ramai lecturer mcm prof jojo....sob sob sob...

after this dier nk balik india..dier tak boleh sambung kontrak kt UM sbb2 tertentu...
Thank you, prof jojo..thank you for the knowledge. Thank you for the awesome class. Thank you for the awesome lecture. Thank you for the fun.

curik2 amik gambar masa tgh amik kertas~

Sofwah tersenyum gumbira~
Syed n linda pn tersenyum gumbira~
kanak2 riang!
Goodbye Prof Jojo~We will miss you! :(
