The First Goal : ACM ICPC World Final 2009!

The name “NTUsiasm” is given by Wendy, it’s better than the first one he proposed, hehe…

“Mathematicians won the war. Mathematicians broke the Japanese codes and built the A-bomb. Mathematicians… like you. The stated goal of the Soviets is global communism. In medicine or economics, in technology or space, battle lines are being drawn. To triumph, we need results. Publishable, applicable results. Now, who among you will be the next Morse? The next Einstein? Who among you will be the vanguard of democracy, freedom, and discovery? Today, we bequeath America’s future into your able hands. Welcome to Princeton, gentlemen.”

Here is the result of my-calculus-class’s photo at Jonas Studio…

So sad to leave you soon. I found it quite nice being with you all during my first semester, though maybe I only remember about 20 names (it’s hard for me to remember names). But I’m sure that I can remember faces, hehe… Well, I’ve arranged to see you all in 3rd January, coz I will try the final exam of calculus, hehe… Good luck… See you…

Oh ya, last one, sure, you all can keep in touch with me, just add my FriendSter account (you can access it via the sidebar) or just add my YM account (microbrain_x).

ITB Mathematics Expo, 22-24 November 2007

Yesterday I attended one of several events in ITB mathematics expo. That was a seminar titled “How Would Picasso Look At Math?”. The speakers are Mr Iwan Pranoto Ph.D (senior mathematics lecturer from ITB) and Mr Sujiwo Tejo (famous artist).

Besides the seminar, as the title, there was also a mathematics exhibition. I found some mathematics jokes, maybe those aren’t something new, but still funny for me.

2007 Nobel in Economics: Designing Better Markets

This is the VOA Special English Economics Report.

Many things perform effectively but not efficiently. To be efficient means to produce a desired effect with as little waste as possible.

How can markets be designed to make them more efficient? This is a question that the three winners of this year’s Nobel Prize in economics have tried to answer. They established mechanism design theory.

Leonid Hurwicz

It began with work by Leonid Hurwicz of the University of Minnesota in nineteen sixty. Eric Maskin of the Institute for Advanced Study in Princeton, New Jersey, and Roger Myerson of the University of Chicago further developed it.

The three Americans will share the award worth about one and a half million dollars. The Royal Swedish Academy of Sciences announced the winners this week.

In everyday life, there are many things that get in the way of efficient markets. There may not be true competition. Buyers and sellers may keep some information private from each other. Also, the production and use of goods may result in outcomes like pollution or social costs.

Eric Maskin

Mechanism design theory permits economists to identify situations where markets work well and where they do not. For example, it shows why an auction is generally the most efficient way to sell many kinds of goods.

In fact, experts say the theory explains why a version called a double auction is often the best way to trade. In a double auction, buyers and sellers both make price bids.

The Swedish academy says the theory also explains why there is often no good market solution to providing some goods, like uncrowded roads.

Mechanism design theory is part of the wider economic idea of game theory and it has many uses — including in political science.

Roger Myerson

Roger Myerson even built a mathematical model for elections. He found a voting system that he says would have helped Florida avoid its problems in the two thousand presidential election.

The Nobel Prize award ceremonies will take place on December tenth. The official name of the economics award is the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. The Swedish central bank created the prize in nineteen sixty-eight.

Leo Hurwicz was born in Russia in nineteen seventeen. He developed new ways to understand markets. He began his work after World War Two. At ninety years old, he is the oldest person ever to win a Nobel Prize.

And that’s the VOA Special English Economics Report, written by Mario Ritter. I’m Bob Doughty.

Hmm, in order to improve my english skill, I think it will be better for me to start writing in English, including in this blog. So, welcome to my “new languaged” blog. Enjoy it!

(Thanks also for Mr.Chriswan Sungkono who have encouraged me to do this, glad to learn English from you)

Hmm, sebenarnya gw udah buat soal ini sejak lama (sekitar setengah taun yang lalu), tapi lupa aja mau masukin ke blog ini, jadi baru sekarang deh.

Nih soal analisis bilangan buat yang suka utak-atik matematika:

Perintah : Gantilah huruf-huruf yang terdapat dalam persamaan di bawah ini dengan angka unik dari 1-9.

MASALAH

Harusnya kalian pada bisa. Lagian pernah ada someone yang bilang nih soal masih kurang bagus (dan gw juga cukup setuju) karena solusinya gak unik, alias lebih dari 1 (tepatnya ada 4 kombinasi solusi).

Well, just try to solve it.
