Thriller


It’s Close To Midnight And Something Evil’s Lurking In The Dark
Under The Moonlight You See A Sight That Almost Stops Your Heart
You Try To Scream But Terror Takes The Sound Before You Make It
You Start To Freeze As Horror Looks You Right Between The Eyes,
You’re Paralyzed

‘Cause This Is Thriller, Thriller Night
And No One’s Gonna Save You From The Beast About Strike
You Know It’s Thriller, Thriller Night
You’re Fighting For Your Life Inside A Killer, Thriller Tonight

You Hear The Door Slam And Realize There’s Nowhere Left To Run
You Feel The Cold Hand And Wonder If You’ll Ever See The Sun
You Close Your Eyes And Hope That This Is Just Imagination
But All The While You Hear The Creature Creepin’ Up Behind
You’re Out Of Time

‘Cause This Is Thriller, Thriller Night
There Ain’t No Second Chance Against The Thing With
Forty Eyes
You Know It’s Thriller, Thriller Night
You’re Fighting For Your Life Inside Of Killer, Thriller Tonight

Night Creatures Call
And The Dead Start To Walk In Their Masquerade
There’s No Escapin’ The Jaws Of The Alien This Time
(They’re Open Wide)
This Is The End Of Your Life

They’re Out To Get You, There’s Demons Closing In On Every Side
They Will Possess You Unless You Change The Number On Your Dial
Now Is The Time For You And I To Cuddle Close Together
All Thru The Night I’ll Save You From The Terror On The Screen,
I’ll Make You See

That This Is Thriller, Thriller Night
‘Cause I Can Thrill You More Than Any Ghost Would Dare To Try
Girl, This Is Thriller, Thriller Night
So Let Me Hold You Tight And Share A Killer, Diller, Chiller
Thriller Here Tonight

RAP

Darkness Falls Across The Land
The Midnite Hour Is Close At Hand
Creatures Crawl In Search Of Blood
To Terrorize Y’awl’s Neighbourhood
And Whosoever Shall Be Found
Without The Soul For Getting Down
Must Stand And Face The Hounds Of Hell
And Rot Inside A Corpse’s Shell
The Foulest Stench Is In The Air
The Funk Of Forty Thousand Years
And Grizzy Ghouls From Every Tomb
Are Closing In To Seal Your Doom
And Though You Fight To Stay Alive
Your Body Starts To Shiver
For No Mere Mortal Can Resist
The Evil Of The Thriller

Earth Song


What about sunrise
What about rain
What about all the things
That you said we were to gain.. .
What about killing fields
Is there a time
What about all the things
That you said was yours and mine...
Did you ever stop to notice
All the blood we've shed before
Did you ever stop to notice
The crying Earth the weeping shores?

Aaaaaaaaaah Aaaaaaaaaah
Oooooow

What have we done to the world
Look what we've done
What about all the peace
That you pledge your only son...
What about flowering fields
Is there a time
What about all the dreams
That you said was yours and mine...
Did you ever stop to notice
All the children dead from war
Did you ever stop to notice
The crying Earth the weeping shores

Aaaaaaaaaaah Aaaaaaaaaaah
Oooooow


I used to dream
I used to glance beyond the stars
Now I don't know where we are
Although I know we've drifted far

Aaaaaaaaaaah Aaaaaaaaaaaah
Aaaaaaaaaaah Aaaaaaaaaaaah

ben

Ben (Reference Vocal)


Ben, the two of us MAY look no more
We both found what we were looking for
With a friend to call my own
I'll never be alone
And you, my friend, will see
You've got a friend in me
(you've got a friend in me)

Ben, you're always running here and there
You feel you're not wanted anywhere
If you ever look behind
And don't like what you find
There's one thing you should know
You've got a place to go
(you've got a place to go)

I used to say "I" and "me"
Now it's "us", now it's "we"
I used to say "I" and "me"
Now it's "us", now it's "we"
Ben, most people would turn you away
I don't listen to a word they say
They don't see you as I do
I wish they would try to
I'm sure they'd think again
If they had a friend like Ben
(a friend) Like Ben
(like Ben) Like Ben

you are not alone

You Are Not Alone


Another day has gone
I'm still all alone
How could this be
You're not here with me
You never said goodbye
Someone tell me why
Did you have to go
And leave my world so cold

Everyday I sit and ask myself
How did love slip away
Something whispers in my ear and says
That you are not alone
For I am here with you
Though you're far away
I am here to stay

You are not alone
I am here with you
Though we're far apart
You're always in my heart
You are not alone

All alone
Why, oh

Just the other night
I thought I heard you cry
Asking me to come
And hold you in my arms
I can hear your praye
rs
Your burdens I will bear
But first I need your hand
Than forever can begin

Everyday I sit and ask myself
How did love slip away
Then something whispers in my ear and says
That you are not alone
For I am here with you
Though you're far away
I am here to stay
For you are not alone
I am here with you
Though we're far apart
You're always in my heart
And you
are not alone

Whisper three words and I'll come runnin'
And girl you know that I'll be there
I'll be there

You are not alone
I am here with you
Though you're far away
I am here to stay
You are
not alone
I am here with you
Though we're far apart
You're always in my heart

You are not alone
For I am here with you
Though you're far away
I am here to stay
For you are not alone
For I am here with you
Though we're far apart
You're always in my heart

For you are not alone

korosi

Korosi

Korosi adalah kerusakan atau degradasi logam akibat reaksi redoks antara suatu logam dengan berbagai zat di lingkungannya yang menghasilkan senyawa-senyawa yang tidak dikehendaki. Dalam bahasa sehari-hari, korosi disebut perkaratan. Contoh korosi yang paling lazim adalah perkaratan besi.
Pada peristiwa korosi, logam mengalami oksidasi, sedangkan oksigen (udara) mengalami reduksi. Karat logam umumnya adalah berupa oksida atau karbonat. Rumus kimia karat besi adalah Fe2O3.nH2O, suatu zat padat yang berwarna coklat-merah.
Korosi merupakan proses elektrokimia. Pada korosi besi, bagian tertentu dari besi itu berlaku sebagai anode, di mana besi mengalami oksidasi.
Fe(s) <--> Fe2+(aq) + 2e
Elektron yang dibebaskan di anode mengalir ke bagian lain dari besi itu yang bertindak sebagai katode, di mana oksigen tereduksi.
O2(g) + 4H+(aq) + 4e <--> 2H2O(l)
atau
O2(g) + 2H2O(l) + 4e <--> 4OH-(aq)
Ion besi(II) yang terbentuk pada anode selanjutnya teroksidasi membentuk ion besi(III) yang kemudian membentuk senyawa oksida terhidrasi, , yaitu karat besi. Mengenai bagian mana dari besi itu yang bertindak sebagai anode dan bagian mana yang bertindak sebagai katode, bergantung pada berbagai faktor, misalnya zat pengotor, atau perbedaan rapatan logam itu.
Korosi dapat juga diartikan sebagai serangan yang merusak logam karena logam bereaksi secara kimia atau elektrokimia dengan lingkungan. Ada definisi lain yang mengatakan bahwa korosi adalah kebalikan dari proses ekstraksi logam dari bijih mineralnya. Contohnya, bijih mineral logam besi di alam bebas ada dalam bentuk senyawa besi oksida atau besi sulfida, setelah diekstraksi dan diolah, akan dihasilkan besi yang digunakan untuk pembuatan baja atau baja paduan. Selama pemakaian, baja tersebut akan bereaksi dengan lingkungan yang menyebabkan korosi (kembali menjadi senyawa besi oksida).
Deret Volta dan hukum Nernst akan membantu untuk dapat mengetahui kemungkinan terjadinya korosi. Kecepatan korosi sangat tergantung pada banyak faktor, seperti ada atau tidaknya lapisan oksida, karena lapisan oksida dapat menghalangi beda potensial terhadap elektroda lainnya yang akan sangat berbeda bila masih bersih dari oksida.

Evolusi


Manusia Tak Berevolusi dari Kera


Satu tim ilmuwan internasional pekan ini melaporkan bukti kerangka manusia purba yang hidup 4,4 juta tahun lalu memperlihatkan manusia tidak berevolusi dari nenek moyang yang mirip kera.
Penyelidikan selama 17 tahun mengenai temuan kerangka yang sangat rapuh, kera darat kecil yang ditemukan di wilayah Afar Ethiopia, dibeberkan di dalam jurnal Science terbitan Jumat (2/10).
Sebagaimana dilaporkan kantor berita China, Xinhua, jurnal itu juga berisi 11 berkas mengenai temuan tersebut.
Fosil yang diberi nama panggilan Ardi itu berupa kerangka paling tua dari cabang manusia dari pohon keluarga primata. Cabang tersebut meliputi Homosapiens serta spesies yang lebih dekat dengan manusia dibandingkan dengan kera dan bonobo.
Temuan itu memberi pengertian baru mengenai bagaimana hominid–keluarga kera besar yang terdiri atas manusia, simpanse, gorila dan orang-utan- mungkin muncul dari satu nenek moyang monyet.
Sampai ditemukannya Ardi, tahap paling awal yang diketahui mengenai evolusi manusia adalah Australopithecus. Manusia kera itu berotak kecil dan sepenuhnya berkaki dua hidup antara empat juta dan satu juta tahun lalu.
Fosil Australopithecus yang paling terkenal adalah Lucy berumur dari 3,2 juta tahun, diambil dari lagu Beatles Lucy in the Sky with Diamonds. Lucy ditemukan pada 1974 sekitar 45 mil dari tempat Ardi, belakangan ditemukan.
Setelah Lucy ditemukan ada perkiraan bahwa ketika kerangka hominid jadi anatomi mirip simpanse, berdasarkan kesamaan genetika manusia dan kera. Namun fosil Ardipithecus ramidus tidak mendukung dugaan itu.
Kerangka Ardi cukup lengkap –tengkorak, gigi, tulang panggul, kaki, paha, lengan dan tangan– untuk memperkirakan tinggi dan berat tubuhnya. Ardiberjalan dengan dua kaki di tanah, tapi memanjat pohon dan juga menghabiskan waktu mereka di sana, dan kemungkinan pemangsa segala.
Sesuatu yang mengejutkan ialah Ardi tidak memiliki bagian tubuh seperti kera atau gorila, tapi lebih mirip dengan kera yang punah atau bahkan monyet. Dan kedua tangannya juga tidak mirip tangan simpanse atau gorila, tapi lebih berkaitan dengan kera yang punah sebelumnya.
Banyak ilmuwan mengatakan temuan itu menunjukkan bahwa hominid dan kera Afrika, masing-masing memiliki jalur evolusi yang berbeda. “ita tak lagi dapat menganggap kera sebagai’wali bagi nenek moyang terakhir bersama kita. Temuan (Charles) Darwin sangat bijaksana mengenai masalah ini,” kata Tim White dari University of California Berkeley, yang membantu memimpin tim penelitian tersebut.
“Darwin mengatakan kita harus benar-benar berhati-hati. Satu-satunya cara kita akan mengetahui seperti apa nenek moyang kita dan menemukannya,” katanya.
“Pada 4,4 juta tahun lalu, kita menemukan sesuatu yang sangat dekat dengan itu. Dan, persis seperti Darwin menghargai evolusi garis kera dan garis manusia telah berjalan secara terpisah sejak jalur itu terpisah, sejak nenek moyang terakhir bersama yang kita miliki,” tambah White.

induksi elektromagnetik

=INDUKSI ELEKTROMAGNETIK=



Induksi elektromagnetik pertama kali dipelajari dan ditemukan oleh Michael Faraday pada tahun 1831. Induksi elektromagnetik atau imbas listrik merupakan pembangkitan energi listrik dari medan magnet. Induksi elektromagnetik terjadi pada suatu kumparan jika ada perubahan jumlah garis gaya magnet yang dilingkupi setiap saat. GALVANOMETER adalah alat untuk menyelidiki besar dan arah arus induksi pada suatu rangkaian. Kita dapat membangkitkan GGL induksi dengan cara berikut. 1. Menggerakkan magnet keluar masuk kumparan 2. Memutar magnet di dekat kumparan 3. Memutar kumparan dalam magnet 4. Memutus-mutus arus listrik yang melalui kumparan. Jika jumlah garis gaya yang dilingkupi kumparan bertambah, jarum galvanometer menyimpang ke kanan. Jika jumlah garis gaya yang dilingkupi kumparan berkurang, jarum galvanometer menyimpang ke kiri. Penyimpangan jarum galvanometer ke kanan dan ke kiri tersebut menunjukkan bahwa GGL induksi yang dihasilkan kumparan berupa tegangan bolak-balik/AC (alternating current). Jika GGL induksi lebih besar, kuat arus induksi yang timbul juga lebih besar. Menurut Faraday, besar GGL induksi pada kedua ujung kumparan sebanding dengan laju perubahan fluks magnetik yang dilingkupi kumparan. Artinya, semakin cepat terjadinya perubahan fluks magnetik, makin besar GGL induksi yang timbul. Adapun yang dimaksud FLUKS adalah banyaknya garis gaya magnet yang menembus suatu bidang. Ada berapa faktor yang menentukan besar GGL induksi yang diketahui dari besar penyimpangan jarum galvanometer. Jika kamu melakukan percobaan ini secara teliti dengan mengubah-ubah jumlah lilitan, kecepatan gerak magnet, dan kekuatan magnet yang digunakan, kamu akan dapat menyimpulkan bahwa besar GGL induksi bergantung pada tiga faktor, yaitu: 1. Jumlah lilitan pada kumparan 2. Kecepatan gerak magnet keluar-masuk kumparan 3. Kekuatan magnet batang yang digunakan. Induksi elektromagnetik saat ini sudah banyak dimanfaatkan untuk keperluan hidup sehari-hari. Orang pertama yang menyelidiki dan menemukan hal tersebut adalah MICHAEL FARADAY. 1. GENERATOR Generator (dinamo) merupakan alat yang prinsip kerjanya berdasarkan induksi elektromagnetik. Alat ini pertama kali ditemukan oleh Michael Faraday. Generator adalah mesin yang mengubah energi kinetik menjadi energi listrik. Energi kinetik pada generator dapat juga diperoleh dari angin atau air terjun. Berdasarkan arus yang dihasilkan, generator dapat dibedakan menjadi dua macam, yaitu gerator AC (alternating current) dan generator DC (direct current). Generator AC menghasilkan arus bolak-balik dan generator DC menghasilkan arus searah. Baik arus bolak-balik maupun searah dapat digunakan untuk penerangan dan alat-alat pemanas. a. GENERATOR AC Bagian utama generator AC terdiri atas magnet permanen (tetap), kumparan (solenoida), cincin geser, dan sikat. Pada generator, perubahan garis gaya magnet diperoleh dengan cara memutar kumparan di dalam medan magnet permanen. Karena dihubungkan dengan cincin geser, perputaran kumparan menimbulkan GGL induksi AC. Oleh karena itu, arus induksi yang ditimbulkan berupa arus AC. GGL induksi yang ditimbulkan oleh generator AC dapat diperbesar dengan cara: ¤ memperbanyak lilitan kumparan, ¤ menggunakan magnet yang lebih kuat, ¤ mempercepat perputaran kumparan, dan ¤ menyisipkan inti besi lunak ke dalam kumparan. b. GENERATOR DC Prinsip kerja generator (dinamo) DC sama dengan generator AC. Namun pada generator DC arah arus induksinya tidak berubah. Hal ini karena cincin yang digunakan pada generator DC berupa cincin belah (komutator).

patung

Patung


Patung David karya Michelangelo, salah satu karya patung terkenal
Patung adalah benda tiga dimensi karya manusia yang diakui secara khusus sebagai suatu karya
seni. Orang yang menciptakan patung disebut pematung. Tujuan penciptaan patung adalah untuk menghasilkan karya seni yang dapat bertahan selama mungkin. Karenanya, patung biasanya dibuat dengan menggunakan bahan yang tahan lama dan sering kali mahal, terutama dari perunggu dan batu seperti marmer, kapur, dan granit. Kadang, walaupun sangat jarang, digunakan pula bahan berharga seperti emas, perak, jade, dan gading. Bahan yang lebih umum dan tidak terlalu mahal digunakan untuk tujuan yang lebih luar, termasuk kayu, keramik, dan logam.
Dimasa lalu patung dijadikan sebagai
berhala, simbol Tuhan atau Dewa yang disembah. Tapi seiring dengan makin rasionalnya cara berfikir manusia, maka patung tidak lagi dijadikan berhala melainkan hanya sebagai karya seni belaka. Fenomena pemberhalaan patung ini terjadi pada agama-agama atau kepercayaan-kepercayaan yang politheisme seperti terjadi di Arab sebelum munculnya agama samawi. Lihat juga arca. Mungkin juga dalam Hindu kuno di India dan Nusantara, dalam agama Buddha di Asia, Konghucu, kepercayaan bangsa Mesir kuno dan bangsa Yunani kuno.

Elektromagnetik

Elektromagnetisme

Elektromagnetisme adalah fisika tentang medan elektromagnetik: sebuah bidang dalam fisika, yang mempelajari ruang, yang terdiri dari medan listrik dan medan magnet. Medan listrik dapat diproduksi oleh muatan listrik statik, dan memberikan kenaikan pada gaya listrik, yang menyebabkan listrik statik dan membuat aliran arus listrik dalam konduktor listrik. Medan magnetik dapat diproduksi oleh gerakan muatan listrik, superti arus listrik yang mengalir sepanjang kabel dan memberikan kenaikan pada gaya magnetik yang dihubungkan dengan magnet. Istilah "elektromagnetisme" berasal dari kenyataan bahwa medan listrik dan magnet adalah saling "berpelintiran", dan, dalam banyak kondisi, tidak mungkin untuk memisahkan keduanya. Contohnya, perubahan dalam medan magnet memberikan kenaikan ke medan listrik; ini adalah fenomena dari induksi elektromagnetik, yang merupakan dasar dari operasi generator listrik, motor induksi, dan transformer.

Istilah elektrodinamika kadangkala digunakan untuk menunjuk kek kombinasi dari elektromagnetisme dengan mekanika. Subjek ini berhadapan dengan efek dari medan elektromagnetik dalam sifat mekanika dari partikel yang bermuatan listrik.
