This colorful door belongs to Beyaz Konak(White House) in Midyat, a historic town in Mardin, Türkiye. Midyat is famous for its ancient stone houses, ornate doors, and handcrafted silverwork (telkâri).
Each pattern and color tells a story from centuries of coexistence and craftsmanship.

Hasta siempre, Pepe.
Gracias por no venderte.
Gracias por hacernos pensar que otro mundo sí era posible.
Aunque fuera desde una casita con goteras y un perro viejo en el patio.
RIP

🌍 Happy Earth Day!
Today’s a reminder that we don’t inherit the Earth from our ancestors—we borrow it from our children. 🌱
Let’s care, protect, and restore—every small action matters. 💚

Pomegranate-shaped ornament, which scripted verses from the Qur’an. The pomegranate symbolizes abundance, fertility, and divine blessing. It’s sometimes associated with paradise and is mentioned in the Qur’an as one of the fruits of heaven.

My dad used to go to school with it.

I'm a retired teacher. It's time for Texas schools to retire STAAR.

Hemoglobin, the molecule that carries oxygen in humans, is damn near exactly the same as chlorophyll, the molecule that plants use for photosynthesis. The main difference is that at the core of hemoglobin is an Iron atom while in chlorophyll there is a Magnesium atom.

This sewing machine is a magnificent example of 19th-century elegance and craftsmanship! Although it looks different than today’s technology, reflects the appreciation for handwork and engineering of its time. Its aesthetic decorations and sturdy structure, it`s masterfully designed tool of its era.
