Scent of a volume

Wavelengths of light are perceived as color, and frequencies of sound are perceived as pitch; however, it is not known what properties of a molecule are perceived as smell. In this study, we are the first to show that the molecular volume of an odorant is an important factor in the fruit fly ( Drosophila ).  Odorant molecular volume affects two dimensions of smell: intensity (weak or strong) and quality (sweet, floral, fruity, and similar factors). Molecular volume might explain the #scent differences between methanol and butanol, which are two similar molecules of different sizes.  Methanol smells pungent, whereas the scent of butanol is similar to wine with a slight banana-like aroma.

Conspiracy Theory

I made this figure while I was practicing Python.

• There are some Observations (black dots).
• The green line is a possible theory which describes the observations with some errors.
• The red curve is one of many possible Conspiracy Theories that fits perfectly to the data.
• Here is the underlying reality!

Love

Love is a spontaneous symmetry breaking.

Green ferry

Since 18th century, the two sides of the river in this photo are connected by a ferry. The ferry does not have any sails or engines. It just moves by the current of river.

Playgrounds in Tehran

Playgrounds really amuse me, even though I am not a child any more. Whenever I pass by one, I stop and watch children playing. If no one plays there, that is even better, for I can go and play.
Among all structures installed in playgrounds, I like those which help children to develop mental, physical or social skills more while keeping them amused. Unfortunately these sort of playgrounds are rare objects in my city Tehran. Even worse, their number is decreasing. It was just a few years ago when my favorite childhood ride in a park -- a circular maze made of cement walls -- was knocked down and replaced by a much less creative structure -- a roller skating rink.
It is sad to see the negative trend and as an ordinary citizen maybe I can not do much to improve the situation. However, at least I can do one simple thing. I can convince other citizens to demand authorities to build slightly more creative playgrounds.

300 Spartan

After all the stories about the protest against 300 the movie , I got the original comic book by Frank Miller and read it all. It was kind of interesting ...

"You fight for your lands? Keep them! You fight for Sparta? She will be wealthier and more powerful than ever before! You fight for your kingship? You will be proclaimed warlord of all Greece ... Answerable only to the one true master of the world!

Your victory will be complete... If you but lay down your arms and kneel to holy Xerxes!"

Does this dialog remind you something?

Tool-tip for labels

It is a while that I have switched to blogger in beta . My main reason was the new label features. Thanks to labels, I can write whatever I like and readers can read whatever they choose. But, after working a little bit around I realized that something is really missing. Each label is a at maximum a couple of words that can not carry much of information so it would be good to have a tool-tip for each label that shows a short description when you move the mouse over it. Something like below:

Labels

• english (9)
• epigram (14)
• life (15)
• photo (7)
• story (11)
  
• tehran (5)

Only one more Layouts Data Tags for labels to store these comments.

From Template to Layout

I am moving from the old template to the new layout system. Let me know if you see any problem in the blog.

BETA BLOGGER

Just moved to the beta blogger. The only problem was the Persian text inside the template. They loses the right encoding and you have to retype them.
Now I am waiting for the labels to be available for HTML edited template.

There is one thing worse than being a single girl, 25, Msc and 160cm. It is being a single girl, 30, PhD and 175cm.

My Italian friend just said:
''I saw that your president decided to forbid the use of foreign names
and so the pizza will be called "elastic bread" in Farsi
So to protest I will call Zafferano yellow powder.''

دوست ایتالیایی من گفت که:
دیدم که رییس جمهورتان استفاده از لغات خارجی را ممنوع اعلام کرده است و بنابراین پیتزا »نان کشسان« نامیده خواهد شد. من هم برای اعتراض زعفران را »پودر زرد« خواهم نامید.

Anonymity

It is wonderful to be anonymous, to be seen but remain unidentified, to attract but leave them alone with the mystery and the most, to hide the face instead of the soul.

The day after tomorrow

The day after tomorrow is a good SCIENCE-fiction movie with more weight toward the science part. To my opinion, the only fiction in it, is the good ending. I think in the real world, the US will invade to Mexico and then they will slaughter the local population so they will be able to establish a new country. In fact, Mexico will be erased and the United State will be shifted there. Do not say that I am so pessimistic, this had happened many time before, still happening now and can happen again.
