London 2012 Olympics — medal statistics
The 2012 Olympic Games officially ended this Sunday in London. Although I missed most of the games, I was still entertaining myself with some hilarious news, such as Thomas’s re-diving. So much fun. I would remember this for years 🙂 Games ended. Medals won. I’d like to present the medals won by each country in this interesting Olympic ...

Project Euler — problem 18
The 18th Euler problem is sorta a route finding problem. It has occupied my mind for two days. Finally I came up to a clever solution. Find the maximum total from top to bottom of the triangle below: 75 95 64 17 47 82 18 35 87 10 20 04 82 47 65 19 01 23 75 03 34 88 02 77 73 07 63 67 99 65 04 28 06 16 70 92 41 41 26 56 83 40 80 70 33 41 48 72 33...

London 2012 Olympics — Lead, tin and zinc
Folks at WSJ were funny. They gave another medal list of London 2012 Olympic Games, not for the first place but for the last place. They replaced Gold, Silver and Bronze with Lead, Tin and Zinc. No matter who came up to this idea, it’s interesting. As it’s still a part of this Olympic Games, I’d like to present their uncommon medal l...

London 2012 Olympics — Medals per hundred players
It’s the weekend. I just woke up from a nap. Got my mind freshed. I’d like to continue with my digging into the Olympics medal results. Today, I cited the number of participants from each country (see wikipedia). I want to see how efficient each country was, i.e. won more medals with less layers. Here comes the list (snapshot below, click ...

London 2012 Olympics — Medals per event
It’s almost midnight. Before I go sleeping, I’d like to post the chart about ”medals per event” on 2012 Olympics. As some visitors suggested, I searched for the competition information for each athlete. Finally, thankful to the mighty Guardian datablog, I find the integrated spreadsheet. Now, we have this data chart on Medals per event...

London 2012 Olympics — world record in women 400-metre medley
I’ve been going through the medal statistics in London 2012 Olympics recently. I was planning to present some extra charts, such as medal-per-milli-population or medal-vs-GDP. However, it’s a little boring to present the same kind of charts. Thus, I’d like to look into some particular sports in detail. The first one is the world record...

London 2012 Olympics — Men and Women 400-metre medley
Alan brought up the suspicion to Ye’s world record in women 400 metres individual medley. And I quote: “Her last split caused controversy (deep suspicion of doping) as she swam it faster than the fastest male swimmer. I wonder how commonly this occurs in swimming. In running the numbers are well known: the convergence of male/female maratho...

London 2012 Olympics — Medals vs GDP and population
It’s already midnight. I’m sitting near my bed. And before going to bed, I’ll type my last post on London 2012 Olympics. Olympic games are not only individual competitions, but also the reflections of countries’ strength. This is one reason why Olympics data is worthy to study. Researches have indicated that the performance of one coun...

googleVis — NASA’s exploration of Mars
After generating a few interactive charts with googleVis, I realized that it’s a great way to visualize numeric data, especially multi-dimentional data. Days ago, my colleague sent me a picture taken by Curiosity from Mars. He was crazy about it and claimed that this is the real science human should do. To be honest, I’m not as a big fan as ...

Today, I’m gonna to solve the 19th problem. You are given the following information, but you may prefer to do some research for yourself. 1) 1 Jan 1900...
