I’m not good in math but there’s always someone worse (and creative):

Got this funny picture via an email.

Ah this is quite interesting, an excerpt from Fooled By Randomness by Nassim Nicholas Taleb, page 159:

The Birthday Paradox

The most intuitive way to describe the data mining problem to a non-statistician is through what is called teh birthday paradox, though it is not really a paradox, simply a perceptional oddity. If you meet someone randomly, there is a one in 365.25 chance of you sharing their birthday, and a considerably smaller one of having the exact birthday of the same year. So, sharing the same birthday would be coincidental event that you would discuss at the dinner table. Now let us look at a situation where there are 23 people in a room. What is the chance of there being 2 people with the same birthday? About 50%. For we are not specifying which people need to share a birthday; any pair works.

Now 50% is really high chance! Bet you never thought of that. Well, you could read more at Wikipedia for the exact math of The Birthday Problem or the Birthday Attack.

The following video is a parody of “I Will Survive” that mentions calculus and a bunch of stuff a mathematics genius can pretty much relate to. Not me, but still, I enjoyed it.

Ah, math for the KFC lovers.

(x + 2)(x - 2) = 0
x = KFC

Having Posts cereal, banana nut crunch and milk for supper. Kinda hungry suddenly. I have to do math unfortunately. I don’t know what I am doing half the time but well… No choice.

Tomorrow is math exam already; wish me luck.

Ahh… My math test is tomorrow and I don’t think I can finish studying it. I am picking questions to study already, even then I am not able to do the workings fast enough.

I guess I probably won’t do well in math. Probably a pass since it’s actually pretty hard to fail. You have to try really really hard to fail an exam at my university. The passing grade is 35 I think. Someone lecturer even told me it’s 30. I think they set the standards too low already. I guess they want everyone to pass.

Looking at the list below makes me a little nervous.

Examinations are coming

• Mathematics For Computing (6 May)
• Information Systems: Foundations of E-Business (9 May)
• Introduction to Computing and the Internet (12 May)
• Introduction to Java and object-oriented programming (15 May)

There are just so many things to study and I don’t know where to begin actually.

I haven’t actually started to read through the stuff that’s coming out for examinations. I don’t really have a lot of time to do that. I think I’m getting a little stressed with my work too. I wonder if I’ll be able to get through this and still get the good results and the produce good work. I still have another concern though and that concern is perhaps the most troubling.
