Couscous this Sunday

I keep a “ritual”: preparing couscous the first Sunday of every month.

Tunisian couscous can be found in Japan:

Today, I chose to make couscous with Saba (Mackerel in English). A Tasty and oily blue fish!

To make Leben, the trick is a plain Japanese yogurt, well mixed with small quantity of water.

... and Voilà! My Sunday's “tasty” Tunisian couscous with Saba, eaten while enjoying good Tunisian music:

Nothing better than a good time reading after such yummy lunch... until falling asleep...

Dido's problem

The legendary Phoenician princess Dido (عليسة) founded Carthage (814 B.C). The city, then, possessed economic, cultural, and military power in the Mediterranean during Punic and Roman eras.

There is a mathematical problem named after Dido:

"Given a fixed perimeter, which geometric shape gives the maximum surface?"

Dido's problem is inspired by a fascinating and romantic legend. The fixed perimeter is the length of the thin thread that Dido made from the skin of a bull. The maximum surface is the semi-disc which was the land on which she founded the city of Carthage. Surprisingly, Dido solved the problem. Wasn't she clever and talented in Mathematics?

Sadako Sasaki

Sadako's story is perhaps the most moving stories from Japan: Sadako was a girl from Hiroshima who was 2 year-old the 6th of August 1945 (the day of Hiroshima Atomic Bombing). As a consequence, she developed a cancer (leukemia).

The tradition in Japan says that if we make 1000 origami cranes, our most cherished wishes will come true. She wished to recover, she wished no more wars in the world... Thus she made 1000 origami cranes... She died when she was 11 year-old...


Moved by her story, people from around the world began to make origami cranes and send them to Hiroshima. Today in the children's peace memorial in Hiroshima, there are millions and millions of origami cranes.

Welcome Ramadan

In Japan, Ramadan begins on Saturday, 22nd of August. I would like to wish all of my dear readers a blessed and peaceful Ramadan!

Regardless of where a Muslim lives, it is a custom during Ramadan to break the daily fast at sunset with few dates. I received a package of dates from my Aunt in Tunisia. Glad to break my fast with sweet dates from home!

From the summit of Mt. Fuji...

The sun rise. Despite of the cloud, the view was amazing.

The reflection of sunshine on the clouds is impressive.

The crater or the hole of the volcano.




Mt. Fuji is a desert of lava erupted from the volcano. It is amazing that life is appearing again on 3000 meters.




Climbing Mt. Fuji

Mt. Fuji is Japan's highest mountain of 3776 meters. Mt. Fuji is open to the public for climbing, from 1st of July until 31st of August.

Last weekend, I climbed Mt. Fuji with my friends. We started the adventure on Saturday at 20:00. We planned to see the sun rise from the top. We reached the summit after 9 hours and half! The ascension was difficult, a lot of rocks. I used my hands to climb. Moreover, the higher we are, the stronger the slope is.

On the top, it was windy and cold (2 degree). The hole of the volcano is breathtaking, it is so huge, deep and scary. There are beautiful black and red rocks around the hole. I brought couple of them for my collection.

On my way to the top, I met a 7 years old boy with his father. The child was crying while climbing. He is brave. Some people couldn't pursue their way without taking rest. They slept on rocks and sand in the middle of the ascension.

After three hours of rest on the summit (we spent one hour in the long queue for toilet), we started the descension on Sunday morning at 8:30. It took 4 hours. Going back needs more concentration and less physical effort. The way is slippery and rocky. We had to go through clouds where we barely can see. Thanks God, I brought my raincoat, otherwise I would catch a cold.

Now, I am glad that I could realize the most challenging item in my To-do list of my stay in Japan. This experience allowed me to test my stamina. However, once back, my muscles and feet were aching so much. I spent Monday sleeping and relaxing. Today, I feel much more better.

Mt. Fuji needs preparation. The climbing will be easier if you exercise regularly.

The following is a list of item that I think necessary to climb Mt. Fuji:
  • A strong climbing stick (cane) is crucial for safe ascension and descension.
  • Winter clothes are necessary to keep warm on the summit.
  • Raincoat in case of rain.
  • Oxygen bottle, especially for people having asthma.
  • Good shoes for climbing.
  • Food, sweets and minimum 2 liters of water.
  • Gloves for climbing with hands.
  • Torch and extra batteries. It is better to have a torch that you can attach on your front or hang around your neck so that you have your hands free.
  • Rubbish bag because it is forbidden to leave rubbish on Mt. Fuji. You should take everything home.

According to the website, Lend for Peace was founded by four students in America: two Jews and two Palestinians.

1st of July... toward freedom of expression

The Tunisian blog sphere used to write about freedom of expression in July 1st. This year, several posts are dedicated to Internet censorship in Tunisia.

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

This dialogue happened upon my arrival to Japan.

Professor: Is your PC working fine? Did you manage to connect it to the Internet?

Me: Yes, everything is working great. Thank you.

Professor: Our lab has a good Internet speed. This is convenient for you to communicate with your family and friends during your free time.

Me: Thank you very much. (happy)

Professor: Think carefully before criticizing your government in your e-mails, your government might have ways to read them. As far as I know, your people cannot express themselves freely to discuss the local politics.

Me: ...

Professor: However, if you want to criticize our Koizumi, please feel free, you are more than welcome, hahahaha

Me: ... (shame)
