Wolfram|Alpha's long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries.

Wolfram|Alpha aims to bring expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. Our goal is to accept completely free-form input, and to serve as a knowledge engine that generates powerful results and presents them with maximum clarity.

Wolfram|Alpha is an ambitious, long-term intellectual endeavor that we intend will deliver increasing capabilities over the years and decades to come. With a world-class team and participation from top outside experts in countless fields, our goal is to create something that will stand as a major milestone of 21st century intellectual achievement.




mari mari kita cicipi....

contoh:
nyelesain persamaan ini
v_1 + v_2 + v_3 = 4
v_1 - v_2 = 10
v_1 - 3v_2 + 5v_3 = 8
ketik saja v1 + v2 + v3 = 4, v1-v2 = 10, v1 - 3v2 + 5v3 = 8
keluar dah hasilnya: v1 = 23/3, v2 = -7/3, v3 = -4/3

persamaan differensial:
y'' – y' - 2 y = 0, y(0) = 1, y'(0) = 2
hasilnya y = e^2x, juga grafiknya

silakan dicoba-coba yang lain, misal taylor series sin x untuk melihat deskripsi fungsi taylor sinus, graph (s + 10)/(s^2 + 4s + 8) untuk mem-plot fungsi transfer

ayo dicicipi...




sedikit review tentang sang creator

Stephen Wolfram (born 29 August 1959 in London) is a British physicist, mathematician, author and businessman, known for his work in theoretical particle physics, cosmology, cellular automata, complexity theory, computer algebra and the Wolfram Alpha computational knowledge engine.

(http://upload.wikimedia.org/wikipedia/commons/b/be/Stephen_Wolfram.jpg)

KutipStephen Wolfram's parents were Jewish refugees who emigrated from Westphalia to England in 1933.[1][2] Wolfram's father, Hugo Wolfram, was a novelist (Into a Neutral Country), and his mother, Sybil Wolfram, was a professor of philosophy at the University of Oxford. He has a younger brother, Conrad Wolfram.[3]

Wolfram was educated at Eton. At the age of 16, he published an article on particle physics[4] and entered Oxford University (St John's College) at age 17. He wrote a widely-cited paper on heavy quark production at age 18.[2]

Wolfram received his Ph.D. in particle physics from the California Institute of Technology ("Caltech") at age 20[5] and joined the faculty there. He became highly interested in cellular automata at age 21.[2] His work with Geoffrey Fox on the theory of the strong interaction is still used today in experimental particle physics.[6]

Wolfram founded the journal Complex Systems in 1987.

He is married to a mathematician and has four children.[7]

Mei kemarin saya juga dapat email tentang peluncuran Wolfram Alpha ini dari Team Wolfram. Masih membaca-baca saja dan coba2.

Keren!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Tidak lama lagi sumber informasi digital akan menguasai dunia...

Haha... Lagi-lagi buatan orang Caltech....

keunggulannya ialah bukan hanya masalah matematika, tetapi (seperti di-claim di website nya) segala sesuatu yang sistematis

...We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything...

coba ketik "richest country", ternyata Liechtenstein lah yg paling makmur per capita, "biggest animal" ialah paus biru, "average temperature" untuk mengetahui rata-rata suhu di tempat anda, atau "relativistic kinetic energy of 1 kg 5000 m/s" untuk mengetahui energi kinetik relativistik

kalo' gw sih lebih suka pake' calc101.com, soalnya calc101 ada step-by-stepnya^^, tapi cuman buat derivate, integralnya nggak ada caranya T_T, harus pake password...T_T...

@hoshikawa
Wow, aku sudah lihat...
Keren juga sih, sayang grafiknya kurang bagus.

Tapi di situ ada tulisan "Powered by Web Mathematica"
"Mathematica" kan produknya Wolfram???

hahaha iya yah, ternyata wolfram derivatenya ada caranya juga, tapi provided by calc101.com... :P mereka berkerja sama kali' yah^^

oh...
ternyata bisa ga pake' pasword buat integral
misal \int f(x) dx= F(x)
nah, kalo' kita turunkan lagi F(x), kita bisa liat deh caranya... =P
