Good morning!
To me, this Austronesian joke never gets old 😂
Malay vs Filipino
The Filipino "pagi" (stingray) is cognate with the Malay "pari"
The Filipino "salamat" & the Malay "selamat" are cognate derived from the Arabic "salam" (= peace), but then evolved differently

In most Austronesian languages—including Malagasy, Malay, Tagalog & Hawaiian, there are always two kinds of “we”
(1) “inclusive we” (us including you; e.g., ‘kita’ in Malay)
(2) “exclusive we” ( us excluding you; e.g., ‘kami’ in Malay)

Sbg saintis, gue justru melihat sangat diperlukan terminologi terjemahan di bahasa kita sendiri demi memudahkan komunikasi & edukasi sains di dlm negeri plus pelestarian diversitas lokal. Ya contohnya akan jauh lebih membumi kalau terminologi di gambar ini bisa diterjemahkan
Tujuan bahasa adalah untuk komunikasi. Walaupun saya selalu berusaha mencari padanan kata. Tapi untuk masalah kesehatan dan sains, ini kontraproduktif.
Menghambat komunikasi dokter & pasien ketika diagnosis.

“Malay Archipelago” per se is a misnomer if used for the entire Indo-Australian archipelago. It’s the legacy of British colonialism & racism that mistakenly paint the diverse locals in a single “race”
It would be just like calling the entire Europe as “the English Continent”
Since it's Alfred Russel Wallace 200th birthday 🎉 I would like to tell you my favorite anecdote from his book "The Malay Archipelago" (1862)
In 1857, Wallace met a man on the Aru Islands who wouldn't belive him that he was from a place called "England"... 1/3

While "salamat" has become "thanks" in Filipino, "selamat" in Malay has evolved to mean "congratulations" or "rescued/saved"
So, Malay peeps don't literally say "good morning", but more like "congratulations morning" or "rescued morning" 😅

Buat gue, yg bathil & jahat tuh maksain keyakinan subjektif elu—yg mengajarkan kebencian irasional sampe menghalalkan tindakan2 diskriminatif & menindas thd kaum marjinal—supaya dijadikan norma yg berlaku ke semua pihak masyarakat tanpa pandang bulu
Ini namanya menggabungkan yg haq dgn yg bathil. Membela Palestina (dan wilayah+bangsa tertindas lainnya) itu perlu, bagus, dan harus diteruskan, tapi LGBT nya tetep salah, dosa, dan harus ditinggalkan.
Jangan sampai kita tertipu. Yang haq tidak akan pernah bersatu dgn yg bathil.

Aplikasi biologi—sesuai namanya—bisa bermanfaat ke segala lini kehidupan apapun bidang pengetahuannya… sains, teknologi, soshum, ekonomi, linguistik, dll … tinggal sebut aja, gak ada yg terkecuali
Sayangnya, kita semua cenderung kejebak dlm bubble sempit, bahkan echo chamber
Biologi, studi yg dulunya dijuluki "Stamp collection", modal hafalan mati doank, sains paling gampang dapet nilai, sains yg ga 'cowo' bgt, sekarang malah semua bidang konvergen ke arahnya.
Karena Biologi sejak Watson & Crick makin ke hulu, reach out Kimia, Fisika & Matematika.

When you study the diversity of freshwater fishes, then looking at maps depicting the topography like this, everything about the species distribution & vicariance becomes to make sense. You could also kind of predict where you are likely to find new species in underexplored areas
