Fisika

ya !

Dunia kita diatur oleh fisika.

Gravitasi menarik seluruh planet di alam semesta,

pesawat terbang berton-ton yang bisa melayang dan tak jatuh dari langit

sepeda yang bisa terus melaju seimbang

semuanya diatur oleh fisika.

Ia bisa sebegitu luasnya karena fisika itu adalah ilmu yang membongkar bagaimana dunia alam semesta kita bekerja.

Mulai dari materi terkecil di alam semesta,

hingga objek super raksasa seperti galaksi

mencoba menelusuri awal lahirnya semesta ini

hingga memprediksi akhir dari semuanya

tapi juga membantu bagaimana hal sehari hari bisa bekerja

termasuk juga untuk hal hal yang menembus batas masuk akal

fisika adalah ilmu tentang segalanya

selamat datang

ke ilmu yang mengatur segala hal di dunia ini.

Bayangkan mempelajari fisika itu kayak kalian menjadi detektif

dengan jejak-jejak yang ada kita menelusuri kenapa suatu fenomena bisa terjadi

begitulah cara Newton menemukan bahwa dunia ini diatur oleh kekuatan hebat tak terlihat bernama gravitasi

Ia hanya mencoba menjadi detektif

tapi kasusnya adalah alam semesta

itu baru satu, masih banyak yang lain

tapi alam semesta memang sudah begini apa adanya dari awal

hanya kita lah yang perlu menemukan peraturan-peraturan nya

dengan terus mengikuti jejak jejak misteri yang ada seperti halnya Newton

dengan semakin banyaknya peraturan alam semesta yang kita temuin

makin banyak teknologi yang bisa kita ciptain buat hidup kita

tapi sebelum kita lanjut Coba jawab 1 pertanyaan ini

apa yang kalian bayangin kalau mendengar kata "Sihir"

mungkin yang kalian bayangin itu kayak begini

tapi percaya nggak percaya lewat fisika sebenarnya sihir beneran itu bisa diciptain

Wifi, GPS, atau telepon itu nggak kelihatan

tapi hal yang nggak kelihatan ini bisa bikin kita ngomong telepati sama orang di bagian dunia lain

tanpa ada sambungan apa-apa

begitu halnya juga ratusan manusia yang bisa terbang kayak burung

atau kereta kuda yang bisa jalan tanpa kuda

atau sebuah benda yang bisa bicara

itu semua adalah sihir

dan ternyata menakjubkan adalah itu hanyalah bagaimana alam semesta bekerja

lewat para detektif hebat dan senjata yang bernama fisika

kita berhasil menemukannya

dan yang lebih menakjubkan nya lagi

masih banyak lagi sihir yang belum kita temukan kan di alam semesta ini.

Oke, jadi fisika itu luas banget

tapi kalau mau belajar dari mana kita mulainya

ayo kita mulai dari sini.

Fisika klasik dengan tokoh pencetusnya Isaac Newton

ini adalah yang paling sering diajarkan sekolah dan cabang fisika yang sangat berguna di keseharian kita

lewat cabang-cabang ini dunia ibarat mesin yang udah kita ketahui rahasianya

segala hal di dunia ini bisa kita prediksi lewat fisika

sampai tahun 1900-an inilah batas bagaimana kita memandang alam semesta

tapi lalu hal misterius terjadi

Planet Merkurius mengitari Matahari lebih cepat dari pada yang seharusnya

begitu pun juga banyak hal-hal aneh yang terjadi di skala sangat kecil

para Fisikawan menduga ada jejak yang menunjukkan bahwa ada sesuatu yang lebih besar diluar sana

sesuatu yang bahkan nggak bisa dijelasin oleh fisika klasik.

Para detektif Fisikawan pun mencoba menelusuri jejak ini

dan benar saja mereka menemukan dua wilayah baru fisika yang belum terjemah dan super gila

Relativitas dan Fisika Kuantum.

Relativitas ditemukan oleh sang jenius Albert Einstein

teorinya ini begitu mengguncang dunia

dan mengubah pemahaman apapun yang pernah kita ketahui tentang alam semesta

jadi Einstein menemukan bahwa dunia kita itu bukanlah objek yang saling tarik menarik

melainkan dunia kita itu ternyata bentuknya adalah seperti kain

bayangin ruang kosong itu adalah kain ini

kalau kita naroh objek yang berat maka kain kita akan ketekan dan jadi bengkok

lalu karena bengkok objek lain di sekitarnya akan jatuh tertarik dan menciptakan efek gravitasi

kedengaran nggak masuk akal ? itu baru permukaan nya

ternyata kain dunia kita ini terikat juga dengan waktu

semakin kain atau ruang kita di bangkok kan maka waktu akan berjalan lebih lambat di daerah sana

untuk simple nya coba bayangin kalian lagi naik pesawat canggih terus ngelewatin ruang yang super bengkok

kalian akan ngalamin waktu yang lebih lambat dari pada lewat ruang yang lurus

intinya, waktu itu bahkan ternyata bisa di bangkok kan, dan di manipulasi.

Relativitas inilah yang berhasil memecahkan misteri permasalahan orbit Merkurius yang aneh

sampai memungkinkan kita punya GPS yang super akurat

tapi di medan lain banyak para detektif juga menelusuri kebalikannya.

Fisika kuantum menelusuri bagaimana dunia super kecil yang menyusun kita semua bekerja

lagi-lagi yang mengejutkan ternyata banyak hal tidak masuk akal terjadi di dunia super kecil ini

contohnya, sebuah objek yaitu elektron bisa berada di dua tempat yang bersamaan

dan juga bisa punya dua wujud sekaligus

ya !

Gila banget.

Meskipun kedengarannya kayak film-film fiksi

Tapi layar yang kalian lihat sekarang dan komputer yang merupakan basis peradaban modern

bisa lahir karena pengetahuan kita di dunia Quantum.

Tapi lalu tantangannya di dunia super kecil ini

banyak peraturan di fisika klasik dan relativitas tidak bekerja.

Ini menimbulkan permasalahan di mana pemahaman dunia kita masih kayak puzzle yang belum lengkap

maka sampailah kita di jurang misteri alam semesta kita saat ini

para detektif masih terus menemukan teori yang bisa menggabungkan segala nya

belum ada yang berhasil hingga saat ini

masih banyak jejak-jejak misterius yang tersisa

yang salah satunya menunjukkan bahwa kita hanya baru menemukan 5% dari peraturan alam semesta ini.

Jika kebanyakan detektif alam semesta adalah orang-orang luar,

temui detektif semesta dari Indonesia.

Pak Husein Alatas ini mencintai fisika berkat guru SMP nya yang mendeskripsikan fisika

sebagai sebuah misteri yang besar.

Lalu karena penasaran ia akhirnya bahkan sampai beli dan membaca buku-buku fisika tingkat kuliah

tentu saja ia tak paham saat itu

apalagi rumus-rumusnya,

tapi ia terus membaca dan membaca tanpa memusingkan satupun perhitungan

karena begitu terpukau nya Iya dengan misteri-misteri alam semesta ini yang belum terpecahkan

dan di belakang buku-buku itulah Pak Husin menemukan deretan nama

deretan nama yang menginspirasi dirinya

untuk menjadi detektif semesta yang hebat

*Sampai ke SMA,

di SMA juga masih

punya passion mau ke fisika"

saya beli buku itu karangan pak sutrisno namanya

di ITB

Jadi dibelakangnya itu ada nama beliau ya

jadi saya baca itu, wah lulusan Berkeley

ambil Fisika Nuklir.

Terus saya langsung berkhayal , bahwa suatu saat saya harus seperti beliau,

berjalannya waktu, SMA. Kebayang targetnya saya masuk ke Fisika ITB

nah, ketemulah orang-orang yang dari SMP itu saya sudah baca tulisan tulisannya.

ya, saya bisa sebutlah ada nama pak Sutrisno tadi, ada pak tehouw liong, ada pak Pantur Silaban

kemudian di ITB saya ketemu semua itu.

Ini kalau bahasa gaulnya namanya

"dreams come true"

Berjuang selama 15 tahun

Pak Husin tak pernah lelah untuk terus bertanya dan mencari tahu tentang semesta ini.

Hingga akhirnya ia mendapatkan gelar doktor

lalu, lewat perjuangannya bertahun-tahun meneliti terus misteri alam semesta

dan juga mendidik detektif-detektif selanjutnya.

Pak Husin akhirnya diangkat menjadi Guru Besar.

Ya. Sebuah gelar tertinggi yang bisa dicapai di dunia akademik.

Semua itu dijalaninya dengan 1 bekal utama

kecintaannya pada misteri dalam fisika

Ia pun punya misi untuk mencetak detektif detektif semesta berikutnya

kalau ia jatuh cinta lewat buku, kedepannya fisika pun juga bisa diajarkan lewat film.

*Saya suka dengan imajinasi-imajinasi film Star Trek, Starwars, kemudian yang paling realistis itu

Interstellar itu yang paling realistis dari semua film yang ada, terus kemaren yang Avenger.

Saya tau itu salah (fiksi).

Satu hal yang begitu besar yang bisa kita pelajari dari fisika

adalah selalu telusuri akarnya,

seperti halnya detektif.

Enggak cuma untuk fisika

prinsip ini akan berguna untuk sepanjang hidup kalian

prinsip ini jugalah yang mengembangkan fisika yang awalnya dibilang cuma sekedar teori

menjadi ilmu yang bisa begitu bermanfaat lewat ilmu teknik.

dari perjalanan luar angkasa hingga robotik,

sampai untuk membuat video game hingga kebutuhan pertahanan,

semuanya butuh bekal ilmu fisika.

Dan ilmu fisika lah yang akan menjadi obor bagi para detektif semesta,

untuk terus mengungkap lebih banyak misteri semesta ini yang sepertinya makin tak masuk akal.

Justru proses misteri inilah yang disebut oleh Einstein menjadi keindahan fisika.

Jadi bagi kalian yang suka bertanya tentang misteri alam semesta ini, janganlah takut untuk mengejar fisika.

Bergabunglah menjadi salah satu detektif semesta ini.

Lalu siap-siap untuk episode selanjutnya,

karena kita akan membahas sebuah ilmu yang bisa mencampur adukan elemen-elemen di dunia ini,

menjadi sesuatu hal yang baru yang tak pernah kita bayangkan.

Inilah dia,

KIMIA
