Maxwell's equations
Maxwell's equations are of great generality. They apply to all charge and current densities, whether static or time-dependent. Together, they describe the dynamical behaviour of the electromagnetic field.
1)∇.D = ρ
2)∇.B = 0
3)∇xE = -∂B/∂t
4)∇xH = J +∂D/∂t

في تاريخ 25 أيّار 1959 تم انعقاد أول مؤتمر نقابي هندسي خلاله تم انتخاب أول مجلس لنقابة المهندسين العراقيَّة، وقد تألَّف ذلك المجلس من النقيب ونائبه وخمسة أعضاء فضلا عن رؤساء الأقسام: الهندسة المدنيَّة والميكانيكيَّة والكهربائيَّة والمعماريَّة والكيميائيَّة، وقد قررت النقابة أن يكون يوم انعقاد المؤتمر الإنتخابي الأول لها يومًا سنويًا للمهندس العراقي، وهكذا فإن الخامس والعشرين من أيّار من كلّ عام هو يوم المهندس العراقي.

كلُّ عامٍ والمهندسون هم أساس الأعمار والتطوّر والأزدهار، كلُّ عامٍ والهندسة رمزٌ للأبداع والذَّكاء والفنْ.

3 words better than “I love you”:
“Friction is negligible”
“Assume ideal gas”
“Assume incomprehensible flow”
“Steady state operation”

Office life before the invention of AutoCAD and other drafting software was quite different.
Prior to the release of AutoCAD in 1982, engineering drawings were all done by hand using different-grade pencils, erasers, T-squares, and set squares.
Even after all the manual labor, if a change was required, the engineers and toolmakers had to start from scratch and make the sketches all over again.
