It's been long since Ive updated my blog. Not because I'm too busy with life, rather there was nothing really new in life.

On March 2, I went for my haircut met a wonderful hairdresser, number 7, after 45mins of waiting. Just when I'm about to get irritated and grumpy about the "not being attended" service, she entertained me. She was in high spirits with excellent hairdressing skills, it took her 5 mins to get my hair done, and she was like "ohh, the Zhang Xue You hairstyle? Ok before walking out here gotta sing me a song." hahaha.

I have also learnt a little Korean, and wrote out my name in Korean. Cool much?

March 3 I went for Ted, signed up to be a volunteer in the committee, and then went back to church for cell. After that was pool till night, followed by usual wushu the following day.

This week, felt like my memory was like a sieve, dont really remember anything so I guess I'm home the whole day, teaching mum English I suppose. Ah Bah's Money, and the compilation of O level Oral.

Tue I had a meeting with the wushu First Class committee at Long John.

Wed I went for bballing with Alvin, and asked Angel along too. Then, played hamtam bola with the scc kids, then settling some minor accident, and barely meets the requirement before null hypothesis would be rejected... lols haha linking leeway for lateness to statistics.

Thur we had a Patching Session, where Tai Sheng Jo and myself would teach each other of our own module. Sheng was a great tutor, its such a waste he did not take on any tutoring jobs or whatsoever, he's really a potential leader.

So that whole day Ive learnt lots. Ive learn ThermoFluids, Econs, Engineering and Accounts.

-------------------------------------------------------------------------------

For ThermoFluids, Ive learnt the definitions of fluids being substance that cannot resist a shear stress without moving and deforms in continuous order. In NOOB terms, something that flow and had indefinite shape. So liquid is nearly incompressible, while gas is highly compressible.

The cool thing is the 3 types of force; the Compressive force where direction of forces meets in the centre, flowing inwards; the Tensile force where direction of forces go outwards, and the Shear Stress where the forces are at tangent to object, just that it such slide pass, like friction pass. So Shear Stress is a tangential force that changes the shape but not volume whereas the other 2 changes both.

Ive learnt viscosity too, the resistance to flow, or the internal friction between molecules to overcome shear stress. Ideal Fluid are Inviscid, whereas Real Fluids are Viscous.

Lastly, the dynamic and static pressure.

--------------------------------------------------------------------------------

For Econs, the 3h lecture from Tai was awesome, but really confusing.

Besides the Demand and Supply topic where Ive learnt last year, there was the Fiscal Policy: Aggregate Demand = C + I + G + (X-M) where C = consumers/household, I = Investments (foreign), G = Government Spending, X-M = Export - Imports. Then there are scenarios of taxation being bad, and the cycle of nation (inflation), which thus links to unemployment and such.

Cyclical: fired/sacked against will
Frictional: In time to come/looking for jobs
Structural: Jobs available do not fit Qualification

Cost-Push Inflation: Supply leftward shift

Demand-Pull Inflation: Demand rightward shift

The gap in between the P0 and P1 is the Consumer Price Index, where output fall, retrenchment occurs, unemployment rises, GDP plummets.

And to add on to that, the MPS (Marginal Propensity to Save) and MPC (Marginal Propensity to Consume). So the change in AD = reciprocal of MPS x change in government spending or tax, where tax decrease happiness, provide lower multiplier, thus not favourable, thus debts occurs to increase government spending.
