Wine could be one of the keys to superconductivity

Yoshihiko Takano, a Japanese physicist that works in a lab in Tsukuba has discovered that alcoholic drinks can help ordinary materials to “turn into” materials that conduct electricity with resistances close to zero. According to Yoshihiko Takano, alcohol could be one of the keys to superconductivity at room temperatures. Maybe some day the Maglev train will need alcohol to run…

“I started using alcohol in my experiments of superconductivity because I like to drink a lot.” – Yoshihiko Takano

Superconductivity
These are the results of Yoshihiko Takano experiments. It looks like red wine is the best type of alcoholic drink to be able to turn an ordinary material in a superconductor.

Calculator with integrated soroban abacus

This calculator with integrated soroban abacus is fabulous. A soroban (算盤, そろばん) is a Japanese abacus. I’ve seen Japanese people that can use a soroban and are able to make quite complex calculations with it much faster than with a calculator.

To learn how to use a soroban this PDF is great.

The most expensive tuna ever sold

In the first auction of the year in the Tsukiji fish market in Tokyo the most expensive tuna in history has been sold for 32.49 million yen (around 300,000 euros/390,000 dollars). The tuna weights 342 kg; however the weight nor the quality was what made it that expensive, but being the first tuna sold in the year 2011. It was bought by the owners of a sushi restaurants chain.
