On This Day : 15 December 1900 (The birth of quantum theory)
German physicist Max Planck publishes his groundbreaking
study of the effect of radiation on a “blackbody” substance, and the quantum theory
of modern physics is born.
Through physical experiments, Planck demonstrated that
energy, in certain situations, can exhibit characteristics of physical matter.
According to theories of classical physics, energy is solely a continuous
wave-like phenomenon, independent of the characteristics of physical matter.
Planck’s theory held that radiant energy is made up of particle-like components, known as “quantum.” The theory helped to resolve previously unexplained natural phenomena such as the behavior of heat in solids and the nature of light absorption on an atomic level. In 1918, Planck was rewarded the Nobel Prize in physics for his work on blackbody radiation.

Other scientists, such as Albert Einstein, Niels Bohr, Louis
de Broglie, Erwin Schrodinger, and Paul M. Dirac, advanced Planck’s theory and
made possible the development of quantum mechanics–a mathematical application
of the quantum theory that maintains that energy is both matter and a wave,
depending on certain variables. Quantum mechanics thus takes a probabilistic
view of nature, sharply contrasting with classical mechanics, in which all
precise properties of objects are, in principle, calculable. Today, the
combination of quantum mechanics with Einstein’s theory of relativity is the
basis of modern physics.

15 Desember 1900 (Kelahiran teori kuantum)
Fisikawan Jerman Max Planck menerbitkan studi inovatif
tentang efek radiasi pada "Benda hitam", dan teori kuantum fisika
modern lahir.
Melalui percobaan fisik, Planck menunjukkan bahwa energi,
dalam situasi tertentu, dapat menunjukkan karakteristik materi fisik.
Menurut
teori fisika klasik, energi adalah semata-mata seperti gelombang fenomena terus
menerus, independen dari karakteristik materi fisik. Teori Planck menyatakan
bahwa energi radiasi terdiri dari partikel-seperti komponen, yang dikenal
sebagai "kuantum." Teori membantu untuk menyelesaikan fenomena alam
yang sebelumnya dijelaskan seperti perilaku panas dalam padatan dan sifat
penyerapan cahaya pada tingkat atom. Pada tahun 1918, Planck dihargai Hadiah
Nobel dalam fisika untuk karyanya pada radiasi hitam.
Ilmuwan lain, seperti Albert Einstein, Niels Bohr, Louis de
Broglie, Erwin Schrodinger, dan Paul M. Dirac, melanjutkan teori Planck dan
dimungkinkan pengembangan mekanika-kuantum,aplikasi matematika dari teori kuantum
yang mempertahankan energi yang bersifat materi dan gelombang, tergantung pada
variabel-variabel tertentu. Mekanika kuantum mengambil pandangan probabilistik
alam, kontras dengan mekanika klasik, di mana semua properti yang tepat dari objek,
pada prinsipnya, dihitung. Hari ini, kombinasi dari mekanika kuantum dengan
teori relativitas Einstein adalah dasar fisika modern.
