حبيت فقط أن أورد هذه المقالة أثرت فيني كتير وخلتني أدرك شي جديد كنت ما بعرفو أو بالأحرى كنت نسيه، ما بعرف يمكن ما تفيد البعض ولكن هي مهمة جدا للبعض الآخر وخصوصا طلاب الطب والهندسة

The Unstable Stability Theorem
By Mennatalla Nouh
Junior Computer Engineer

3 years in engineering, and an undisclosed number of years on the planet Earth. I was
always told things are stable. Stable atoms, stable isotopes, a dynamical system has to be stable, stable waves, cars have to be built stable to be safe! Equilibrium in the demand and supply curve has to be attained to make profits and etcetera. I have
been taught that I must make everything reach a stable state, and reach equilibrium to
succeed.
But what is being stable?
Steady, firm, fixed, lasting, dependable, faithful, or not susceptible to change? They are definitions to the word stable. But is anything around us stable? Is anything around us
not susceptible to change? Are people really faithful? Is anything lasting and fixed? Is anything around us firm? And are we stable and
lasting? The answers to all of these questions is no! What I have learnt in the past few
weeks contradicts all the theories that I have been raised on and that I have been taught.
That, unfortunately, nothing is stable!
With all the technological advancements we are making cars are not stable. They crash
and passengers pass away. Loved ones die or become disabled or hurt badly. This refutes
and negates the stability theory of making cars; this ruins the fantasy that humans are
ever lasting and immortal! If you think of how you can be with a loved one now and 5
minutes from now, he/she could be dead and you can not talk to her or see him again,
ever. You then realize that absolutely nothing is stable.

To conclude, I just want to say keep smiling
and study your theorems well. But just remember,
not every theorem you study will
remain as it is; it will change because like
everything else it is unstable! And not everything
you study applies to real life, and engineering
is one of these things!
