  1. salam kenal…bagus sekali pak…. kalau geometri non euclidean itu bagaimana pak, posting ttg tensor juga dong pak…

    • Salam kenal kembali..

      Geometri Non Euclidean sederhananya bisa dikatakan geometri yg tidak memenuhi postulat parallel (postulat kelima) dari Euclide. Gauss menemukan empat postulat pertama ditambah lawan/negasi dari parallel postulat juga konsisten, sejak itu bermunculanlah bermacam2 geometri yg dikembangkan tidak berpijak pada parallel postulat seperti Hyperbolic geometry dari Lobachevsky dan Bolyai, atau Elliptic geometry dari Riemann, yg disebut jg Riemannian geometry.

      Salah satu penggunaan dari Riemannian geometry, yg didalamnya banyak juga dipakai notasi tensor jg curvature, ialah dalam penurunan rumus teori relativitas.. Einstein beruntung karena pada saat itu telah tersedia peralatan matematikanya salah satunya dari Riemann. coba deh kamu buat artikel tentang itu saya akan baca ^_^

  2. finally I can find you here again, sir.it had been a long time since i got final exams and i was off from social networks. I miss that when you’re explaining trigonometry chapter with animated graphic and programming languages​​.😉 That’s very fun.

  3. wooowwwwww its so much postes and i can read all of them….
    are u doing all your article by yourself or is there any people’s posts that u copied??eheheheh
    but im sure your blog will help others…
    yeahhh good job sir😀

    • Hi, thank you for coming here. I always include the source link or reference when part of my posts come from writings of others. It is a necessity. there are also some stuffs that I share with rely on my memory from what I hear or read, and I forget the source or reference from where. Usually for the latter I do not include the source. Any way one of my motivation to post that stuff on this blog is to share what missing from it to be discuused with other people, and not in the format of scientific papers.
