هذا اول واحد فايز بنوبل بالكيميا وهو الي اكتشف الاشكال ثلاثية الابعاد للمركبات العضويه وهو الي طلع سالفة تدوير الضوء المستقطب وسالفة
Levorotatory / dextrorotatory
الي هنه ال chiralty
والاب الروحي للكيمياء الفيزيائيه
Fun Fact:
اكو كيمياء فيزيائيه واكو فيزياء كيميائيه🙃
+تسريحته حلوه🌚

Fun Fact:
Today it's an established fact that our skeletons are surprisingly malleable. The pure white remains displayed in museums may seem solid and inert, but the bones beneath our flesh are very much alive – they're actually pink with blood vessels – and they're constantly being broken down and rebuilt.
While they still have a blood supply they are pink.
When operating on living bone you can make them look white by scraping off the surrounding membrane, the periosteum, removing the blood supply to the surface of compact bone beneath. This is the densest, strongest part of a bone & its blood vessels run in relatively small numbers inside it, within Haversian canals, each a cylindrical structure composed of concentric layers of collagen mineralised with calcium hydroxyapatite (one of many possible hydroxylated phosphates of calcium).
When handling a preserved bone, without a blood supply, you see the white of the calcium phosphate tinged with the yellow of dried collagen.

واكو مرض* يسوي عضامك سوده
واكو ادويه تسوي عظامك خضره🌚
تتراسايكلين يسويها اخضر مصفر
Isotretinoin
يسويها اخضر فاتح-اخضر طوخ
اعتمادا على فترة استعمالك
*تعديل بالاصح هو مو مرض يسبب السواد
Minocycline black bone disease is a rare finding that can cause concern when unexpectedly encountered during routine arthroplasty. Prolonged minocycline use can cause selective staining of subchondral bone, whilst peri-articular soft tissue and cartilage appear uninvolved.
يعني هو ناتج من علاج
ولذا بالاصح هو اثر جانبي للعلاج ,هو الي سببه

A reminder that I don't want to remember
صور الفضاء كلها عموما هيج وخاصة السديم لان التصوير يكون بالاشعه فوق الحمراء واحنه ما انشوفها فنترجم الاشعه هاي للطيف المرئي
بس مع ذلك جنت متوقع ان اكو جزء من السديم ممكن يرى بالعين المجرده
(كالغبار او الغازات الكثيفه) بس لا يبدو ذلك

-Would you blow up the world?
- No, Trust me bro
- Are you sure?
- Are you not satisfied with the answer "trust me bro" ? 🙂🙂
Then have a lecture on physics
