Hua Luogeng’s 101st Birthday
This doodle was published in November 12, 2011 to celebrate Hua Luogeng’s 101st birthday.
Hua Luogeng (12 November 2011 – 12 June 1985) was a Chinese mathematician who became famous for his contributions to the Number Theory.

You can read some information about him in the Doodle’s page:
Hua Luogeng was well known for two important contributions. One was his work on one of the greatest unsolved mathematical problems, known as Goldbach’s Conjecture…. and yes, it is a little trickier than 1+1, though it involves prime numbers! (We celebrated one of his students, Chen Jungrun, in a previous doodle, who made significant progress on this problem).
Luogeng was also known for his methodology on achieving efficiency, known as “Overall Coordination.” His analogy, taught to most schoolchildren, lays out the premise of wanting to drink tea when you don’t yet have boiled water. The most optimized approach is that you first rinse and fill the kettle and place it on the burner. Meanwhile, you should wash the serving teapot, the tea cups, and prepare the tea leaves. When the water has boiled, you can immediately brew your tea. That’s multi-tasking boiled down for you!
You can always learn something new!
Counting with Count Von Count
I know that this is not the correct place for a doodle dedicated to Count Von Count but five years ago this doodle was published to celebrate the 40th anniversary of Sesame Street. I watched it when I was a child I and I loved Count Von Count who taught children to count. Do you remembere it? There were thunders and lightnings after each number!

Shakuntala Devi’s doodle
Shakuntala Devi (November 4, 1929 – April 21, 2013) was a mental calculator who travel around the World showing her arithmetic talent.
According to Wikipedia:
Examples of the problems presented to Devi included calculating the cube root of 61,629,875, and the seventh root of 170,859,375. […] Devi provided the solution to the aforementioned problems (395 and 15, respectively) before [prof. Arthur] Jensen could copy them down in his notebook.
In the 1982 Guinness Book of Records is mentioned that on June 18, 1980, she demonstrated the multiplication of two 13-digit numbers—7,686,369,774,870 × 2,465,099,745,779—picked at random by the Computer Department of Imperial College, London. She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds.

This doddle was published last year to commemorate Devi’s 84th birthday in a lot of countries of the World.
Finally will be the last?

We were coming back to our apartment and… another Copernicus! How many Copernicus are in Poland? This is made with 100 kg of chocolate and it must be the sweetest one. It was in the ancent Royal Pharmacy and current Cukierna Sowa:
The Royal Pharmacy
Here was the oldest pharmacy in Torun, established in the 14th century by Arnold, an apothecary from Wroclaw. In 1652 the pharmacy was granted the name “The Royal Pharmacy”. A figure of an eagle was placed over the door in the 18th century. From then on it has been called “The Pharmacy under the Eagle”.
It was a nice present before leaving Torun!
