It was January and I was full of love toward you. I was missing you in NYC DownTown. This song and others were my best friends at that trip.

The Periodic Table Expands Once Again
The Periodic Table Expands Once Again
By THE ASSOCIATED PRESS
Published: June 8, 2011k
The elements were recognized by an international committee of chemists and physicists. For now, they are called Elements 114 and 116 — permanent names and symbols will be chosen later.
People are not likely to run into either of them. Scientists make them in labs by smashing atoms of other elements together to create the new ones.
“Our experiments last for many weeks, and typically, we make an atom every week or so,” said Ken Moody, a chemist with the Lawrence Livermore National Laboratory who was part of the discovery team.
In contrast to more familiar elements like carbon, gold and tin, the new ones are short-lived. Atoms of 114 disintegrate within a few seconds, while 116 disappears in a fraction of a second, Dr. Moody said.
Both elements were discovered by a collaboration of scientists from Livermore and Russia. They made them by smashing calcium ions into atoms of plutonium or another element, curium. The official recognition, announced last week, cites experiments done in 2004 and 2006.
In the periodic table, the number of an element refers to the number of protons in the nucleus of an individual atom. Leading the list is hydrogen (H) with one. Sodium (Na) has 11, Iron (Fe) has 26, and silver (Ag) has 47.
In the past 250 years, new elements have been added to the table about once every two and a half years on average, said Paul Karol of Carnegie Mellon University. He chaired the committee that recognized the new elements.
Despite the number 116, the new additions bring the total number of recognized elements to 114 — Elements 113 and 115 have not been officially accepted.
Dr. Moody said he had not talked to his colleagues about what element names to propose to an international group of scientists for approval, although they will have to end in “ium.”
For now, the elements have temporary names derived from their numbers. In recent decades, new elements have generally been named for famous scientists, producing such monikers as nobelium and einsteinium, said Peter F. Rusch, a consultant in Mountain View, Calif., who leads the American Chemical Society committee on nomenclature, terminology and symbols.
Before the two newcomers, the most recent addition to the periodic table came two years ago. Element 112 was named copernicium in honor of astronomer Nicolaus Copernicus.
Making new elements is a byproduct of an effort to discover things about the atomic nucleus, Dr. Moody said. “It’s just basic science,” he said. “And kind of fun.”
Dr. Moody, 56, recalled that the periodic table had 104 elements when he was in high school. At the time, chemists thought the list was about finished, he said.
He added that he recently spoke about his work to some high school students and found them fascinated.
To them the periodic table “is an icon,” he said. “The fact that it can change and it can be added to, I think, is a novel idea for younger people.”
Not so for most older people.
Dr. Moody said he does not talk about his work at parties “because people don’t generally invite you back.”

لشو التغيير!!
قررت أن أكتب ، عن كل شيء و لا شيء . أكتب و أنا ملقية بعرض الحائط كل قواعد اللغة . لن أهتم بزخرفة الكلمات و لم تعد شاعرية النص تعريني اهتماما طالما أن النص يفي بما أريد تصويره من الحنق و الغضب على المجتمع المحيط بي . سواء المحيط بي جدا .. أو ذلك الذي أجده في العمل التطوعي ذي الساعات المحدودة و المنتهي بنهاية الفصل الدراسي الحالي أي بعد ثلاثة أسابيع بالضبط أو بالتقريب !! ثم ماذا!!
العودة إلى اللاشيء .. إلى الروتين الممل الذي يعيشه اغلب الشعب السعودي-إن لم يكن كله ، خاصة بعد انتشار الثورات في الدول المجاورة- باستسلام مستهجن أو غير مستهجن فليس هنالك أي فرق . لأن النتيجة واحدة وردة الفعل واحدة! بل إنها تكاد تكون ثابتة و معروفة مسبقا تجاه أي محاولة للتغيير جذريا كان ذلك أم طفيفاً.
الرد الأول و المقنع تجاه أي محاولة للتجديد هو : إنها مؤامرة يهودية غربية نصرانية و بالطبع لن ننسى اضافة إخواننا الشعية الى القائمة، غرضها إبعاد الشعب السعودي عن الدين الإسلامي الصحيح ، أو بالأحرى عن التقاليد و العادات البائدة المغلفة بسولفان الدين !!!
ما يثير الغضب و يرفع الضغط حقا هو تصديق الشعب السعودي ، بأنه شعب الله المختار و انه خليفة الله في الأرض. بل إنه الشعب المسكين المغلوب على أمره و المُتآمر عليه من قوى العالم الخارجية بدءًا بإيران و انتهاءًا بعد المرور على شيعة العراق و لبنان و اليمن و المنطقة الشرقية ..!
و الغريب في الأمر أنهم ( شعب الله المختار) الوحيدين الفهمانين في الدنيا و الدين ، و التكنولوجي وكل شيء ، مع ان تفكيرهم ينحصر بين ................................ و في نساءهم اللذين يودون لو يستطيعون وأدهم غير أن الطاقة الجنسية المشتعلة لديهم 24 ساعة. من وقت الميلاد و حتى الموت،- لا بل بعد الموت فحوريات الجنة في انتظارهم- لن يجدوا لها متنفساً غير الأفلام الإباحية!!
و
تعبت يا الله !!
