الحمد لله رب العالمين حمدا كثيرا طيبا مباركا
والصلاة والسلام على أشرف الأنبياء والمرسلين.
أم بعد:
أخواني في الله.... كم يسعدني ويسرني أن أبداء معكم في هذه الساحة بتقديم كل ما يفيد في العلوم والتكنلوجيا،لنشر العلم ، ونواجه تحديات العصر بالتعلم والإجتهاد والممارسة العلمية بشتى أنواعها،ولا أخفي لكم أن علوم الفيزياء والرياضيات أصبحت في مقدمة القوى العلمية،التي أخذت الجانب الأكبر في صنع تطور التكنلوجيا وغيرها.... لا أريد أن أطيل معكم، بكوني سأتحدث باللغة الإنجليزية،حتى تتضح المفاهيم بصورة أسرع للدارسين من جميع المستويات...
Here we go, to get the total understanding; I really hope that you should follow the lessons from the beginning. The machinery of the lessons will be in three different areas. First area, physic, which will lead you to the real Physical World and make you known it from Zero as you are a beginner or even have a good level in physic, by any way, I’m going to start with this really interesting area and hopefully that all of you will share me. Second area, will talk about science explanations or even can brief it in one word “Technology”, and this one will lead you to discover the transference of physic theories to practical useful needs. Last area, will talk and discuss the mathematics and all what is related to it in practical life. I really hope that we all are going to enjoy touch and taste the flavor of knowledge.

?What is physics
Humans have always been curious about the world around them. The night sky with its bright celestial objects has fascinated humans since time immemorial. The regular repetitions of the day and night. The annual cycle of seasons. The eclipses, the tides , the volcanoes, the rainbow have always been a source of wonder. The world has an astonishing variety of materials and a bewildering diversity of life and behaviour. The inquiring and imaginative human mind has responded to the wonder and awe of nature in different ways. One kind of response from the earliest times has been to observe the physical environment carefully. Look for any meaningful patterns and relations in natural phenomena, and and build and use new tools to interact with nature. This human endeavour led in course of time to modern science and technology.
That was as the introduction about the general meaning of physics. Now, I’m going to start with the first lesson of physics that is Units and Measurements. And note that you should get any files for tables or figures which belong to the lessons that I will accompany along with them. Have nice learning.
: Units and Measurements
The system of units which is at present internationally accepted for measurement is the system internationale d’ unints( French for International System of Units), abbreviated as SI. The SI, with standard scheme of symbols, units and abbreviations, was developed and recommended by General Conference on Weights and Measures in 1971 for international usage in scientific, technical, industrial and commercial work. Because of the decimal nature of the SI units, based on powers of 10, convenient. SI is the modernized and developed version of metric system.
In SI, there are seven base units as given in the accompanied table “below”, besides the seven SI base units, there are two more units that are defined for plane angle and solid angle. The unit for plane angle is radian with the symbol rad and the unit for the solid angle is steradian with symbol Sr.

That were only as the basics which should be known at the beginning of physics learning. I’m feeling tired so excuse me to complete later. And next time will insert you in bigger fields of physics and technology. Gust, remember to be patient and well followed for me
