Towards mathematical modeling of a tear drop formation: Part one

I was inspired by an image in this blog ( that roughly shows the shape of a tear. it pushed me to think if I can mathematically modulate the formation of tears, and if one can count how many tear drops can a person make per unit time. Then if I can estimate the volume of the total crying lot!
this is an attempt to use some mathematics as a basic tool to describe any phenomenon around us. And because I couldn't attach mathematical symbols directly to the blog page, I had to write and derive everything in a Word page, then save it in parts as pictures then adding them together here. I'll be glad if anyone announce for errors or wrong formulas. Here we go!

Assuming that tears form on the bottom side of a horizontal surface, the free-falling of a tear drop is similar to that of a water drop. It begins with the first secretion amount that has incomplete oval shape, just like if we turn an image of a rising sun upside down. The mass continues to elongate as it is subject to its weight force acting downward. This force is equal to the mass of the tear multiplied by the gravitational acceleration (W=mg). the figure below shows instant magnitudes of diameter of the oval tear as it decreases from both ends. It also shows that the smaller the diameter of the oval tear the larger the value of elongation it gets. This implies that if we consider the diameter reduction a function of time, then at any given time both the diameter and the length are constrained by the relations: di and li>li+1 respectively.

A Golden Rule

almost all chinese people look the same. with slight differences in height, degree of yellow skin, eyes shut angle, and hair. and with common feature among them which is the bad smell coming out from every single pore on their flesh! whenever I had to enter their office in one of my previous works I just spend the fewest possible time and I then run out with their smell penetrating and filling the surrounding of my nasal system. I recently reached the golden rule of recognizing chinese people. it's on the ratio of chin size to the face size. yes I used to face problem distinguishing one chinese person from another, but after this rule I can tell you from the first sight. one day we had a dinner with a delegate of five persons from the chinese partner in my x job. they talk very little. my friend who was in the dinner suggests that they do not talk because of their limited knowledge in English. but I believe their capabilities with English have nothing to do with their silence. it's that they do not feel friendly with the non chinese buddies. they only watch, speak few words when necessary, and then work really hard. any way I tried to initiate a talk with the closest to me and I thought, from his short answers to my complimenting questions, that we became friends. I knew from him that his name is Chu Yang and I was happy of that result. the next morning I saw Chu Yang in the factory working with some papers. I passed by him, smiled and said: good morning Mr Chu Yang. he looked at me and without any emotions on his face replied: I am not Chu Yang, my name is Hu Xing. and I was like: oh sorry .. how are you doing Mr Hu? and I went away. about 2 hours later, I was strolling inside the factory and I found Chu Yang taking data from one machine. I childishly hurried to him and said: good morning Mr Chu Yang, how are you today? he was pissed off when he turned his face to me saying: I told you I am not Chu Yang .. my name is Hu Xing!!!

non cook women

This post comes after Hala’s post on the cooking classes in Le Royal. I’m not criticising but just giving my point of view in this issue. and I succeeded once in linking a word here with a website .. but I couldn't this time link "Hala's post" to her blog so I only highlited it!
Women keep complaining but they never change. All the work sectors are open for the woman but she’s the one who insist to limit herself in what she call “feminine job” and “feminie category”.
I used to have long talks with girls in the engineering college, of course all of them are architects and very few are in chemical or computer eng. departments and you can imagine why! and I used to ask why haven’t you chosen mechanical or electrical or civil eng ? they all had the same answer: “those are not feminine fields!” , or “ mechanical? Do you want me to work with engines?!” or “ civil? do you think it’s a good idea to be a woman directing workers in construction sites?!” .. some girl shocked me because she was very serious saying “ you know, at the end I’m gonna marry, I can’t select to work in a tough environment”!!.
And as for those who actually selected to study mechanical and industrial engineering I met three of them in one factory I worked in, and during that time I never saw one out the office! There was a team work requiring one female engineer to inspect for finished goods in the warehouses, she refused to go because she finds it inappropriate to be in the warehouse in the middle of workers! Later this girl married and disappeared, the other 2 resigned and found an office work in the city, far from factories!
4 or 5 years ago I was in the 8th circle awaiting a taxi, a female driver stopped by me, when I recognized that she’s a woman I hesitated only for a second just to think if I should sit in the front seat or back seat :) but then I made my decision and rapidly approached my hand to the back door. So she said: ma tetla3 goddam shu khawaja 7adertak?! And she moved away! Since then I have never seen a female taxi driver.
I am just giving this example to show that they start brave but they do not continue. And they lack organization and team working to achieve what they target … women are being elected in the parliament but they forget that they represent other women voices in achieving open society for both gender .. they form female committees to serve female issues but not to get involved in real system of men and women. They publish women magazines and broadcast women channels .. all discuss topics like food and beauty and whatever!
I sometimes enjoy cooking , I don’t claim that it’s a feminine issue as might other people do, and some times watch the girls movie night on channel 2 ( what a silly title) … I even worked in the most feminine industry in the world … I worked in Victoria’s Secret factory ( that was a nice experiment by the way with that huge collection of lingerie :) ) . and I do believe that women must work in all sectors … not specifying themselves narrow domains like teaching, nursing and secretary. But it needs a group work … needs continuation .. and strong welling to fight the residual thoughts about women’s domain. Because the society here can accept the woman as she was accepted in Europe, but the woman needs to pay more effort indeed.

Must Be In a Coffee Panel Test

I am a good coffee taster! and I don't use brand names to refer to abstract coffee when talking about it, people for example are used to say: let's drink Nescafé even when the coffee is made of another brand. and for me I have specific times throughout the day when I drink Turkish coffee, Greek coffee, American coffee, French coffee.... etc. when I wake up I no longer need the same type of coffee I drink after lunch, and the evening coffee must fit my circumstance as I'm coming back from work ... it should be with flavor. and even "Abu el 3abed" and "Abu Salih" coffee are only suitable for night driving around the city, or on the way when I go to Irbid. and since I discovered Maxwell House 4 years ago I stopped buying Nescafé. I really like the shape of the coffee granules in MaxwellHouse, and I like the taste of it without any additives ( coffee mate, milk powder or syrup, ..). and as for the Turkish coffee it should be intense and with a very small amount of sweetness, and should contain the upper brown layer (wijih) that comes from the first shoot when boiling, otherwise it's not drinkable.

It's about talking loudly!

in my previous job I used to work in an environment of above thousand employees. in my new job I'm working in an office with up to 15 employees. I prefer working in big factories and I regret somehow that I changed to office work. next time I change my job I will absolutely go back to manufacturing where I can lead workers aggressively and yell freely throughout the day!

Benim Adim Kirmizi

last night I finished reading the Arabic translation of "My Name is Red" by the Turkish writer Orhan Pamuk, the winner of Nobel Prize 2006. it took me something like 2 weeks because of the bad translation, so i could barely finish 10 pages daily in the first week!

but despite what i mentioned about the translation the book is not by any means a quick read. the multiple perspectives that come from the characters make you stumble sometime in learning points of view over the vast range of perspectives and through the narrow miniaturists world in the 16th century.

many things stopped me to think in this book, one of them was:

ولكنني باعتباري نقاشاً عجوزاً أعمى أعرف أن الله خلق الدنيا كما يريد رؤيتها طفل ذكي في السابعة من عمره. لأن الله خلق العالم لنرى أولاً. بعد ذلك أعطانا الكلمات لنتكلم ونشترك فيما نراه، ولكننا عملنا من الكلمات حكايات، واعتقدنا أن الرسوم تنقش من أجل هذه الحكايات، مع أن النقش هو بحث مباشر عن الهام الله ورؤية العالم كما يريد الله

some readers may feel bored reading this novel, I agree, but it's a mentally stimulating read and I liked it.

I advise you to read it ... if you know Turkish it would be better .. otherwise try the English translation because the Arabic was not strong.

How does it go like in Turkey

Today I was reading the BBC Arabic news on their website and found the above article. Turkey is now trying to approach the EU to have itself a membership. and Ankara indeed is doing the best they can to eliminate previous unaccepted impressions about its culture, religion and jurisprudence. now they are banning this website by the higher court in the country just because of a video clip that insulted the founder of modern Turkey, who passed away 67 years ago. and they sentence to prison whoever make an insult about him. I went through Hürriyet, Turkey's famous newspaper and found the topic above in the headlines. what I could understand, which is not much because my Turkish language is not that good, is clear criticism to the insult and agreeing with the court decision.
i just want to refer to that Hürriyet, the name of the newspaper, sounds similar to the meaning in Arabic which is freedom or liberty!
