25 – 55 + (85 + 65) = …
You probably won’t believe it, but this equals 5! Why?
25 – 55 + (85 +65) = 120 (i)
5! = 1 x 2 x 3 x 4 x 5 = 120 (ii)
i = ii
Q.E.D.
There was a girl who was a great nuisance. When she was eight years old, she was already a great trouble maker in her school. She hadn’t done any homework all the time, and she failed in the exam. She twisted her body in the middle of the class and sometimes she stood up and went around the class. Finally, even though the semester didn’t finish yet, the teacher in charge sent the letter to her parents.
“I recommend her sent to special school or receive psychotherapy because she looks scatterbrained.”
Her parents were really disappointed because they somewhat knew she couldn’t pay enough attention, but they didn’t know her teacher would give her up. Next day, her mother took her over to psychological clinic.
“Just sit still!”
Her mother pushed her awfully and talked with the counselor. Then the counselor talked to the girl, “Too boring, isn’t it? But I should more talk with your mother beside the room. Please, wait one more second.”
The counselor spoke while he took the girl’s mother.
“Let’s watch how she behave alone.”
After a while, they were surprised. The girl couldn’t keep still for a while, but then danced beautifully with the music from the psychological clinic. Mesmerized, they just stared at her for a long time. And the counselor spoke to the girl’s mother.
“Your daughter isn’t a trouble maker. She is a born dancer. You should take her to dance academy rather than the special school.”
Her mother felt sorry that she considered her daughter as a great nuisance. And she decided to send her to the dance academy. The girl became happy with a mood different from the school. She practiced dancing from dawn to all day long. Finally, she passed Royal College of Dance, London and then she entered the British Royal Ballet. She became a great ballerina and she succeeded in musical theater troupe after retirement.
This story was about the best ballerina in 20th century and the famous choreographer of “Cats”, and “The Phantom of the Opera”. She is “Gillian Lynne“. Maybe you frustrated because you are just different from others. We may not be able to find our “hidden talent” like “Gillian Lynne”. So, how about making some times and do whatever we really want to do? Don’t even hesitate to discover your talent. Because “your talent” may not be able to meet the ideal setting yet.
Homer: I want to share something with you, the three little sentences that will get you through life. Number one: “Cover for me.” Number two: “Oh, good idea, boss.” Number three, “It was like that when I got here.”
Warden: So, why do you want to be a guard here?
Homer: I believe the children are the future… Unless we stop them now!
Homer: I don’t know, Marge. Trying is the first step towards failure.
Homer: Well, he’s got all the money in the world, but there’s one thing he can’t buy.
Marge: What’s that?
Homer: A dinosaur.
Lisa: I didn’t think you’d understand.
Homer: Hey! Just because I don’t care doesn’t mean I don’t understand!
[Homer’s love letter to Marge where Homer is paralysed and communicates through farting.]
Homer: Dearest Marge, though my body can not move, my heart still beats and my brain still brains. I miss holding you in my arms more than my butt can say. Perhaps some day there will be a cure, although if it requires months of difficult therapy, I’ll pass. You are the shining light that gets me through my darkest hours. For further communication, I will require more beans. I love you.
Homer: I will love you as long as my heart still beats and my brain still brains.
Homer: Son, come here. Of course I’m not mad. If something’s hard to do, then it’s not worth doing. You just stick that guitar in the garage next to your short-wave radio, your karate outfit, and your unicycle, and we’ll go and watch TV.
Bart: What’s on?
Homer: It doesn’t matter.
Homer: Ohhh, why do my actions have consequences?
Moe Szyslak: [After Maya dumps him, Moe is cleaning his empty bar when Homer comes in.] Whatsa matter, Homer?
Homer: Not a thing in the world.
Moe Szyslak: Yeah, I wish I could say the same.
Homer: Moe, this is a great thing for you. You went from sitting on the sidelines to getting in the game! Sometime, when you least expect it, you’ll realize that someone loved you. And that means that someone can love you again! And that’ll make you smile.
Lenny Leonard: Things have changed in the outside while you were gone. Wealthy people can beat the system now.
Carl Carlson: They don’t have parking meters anymore. Now there’s a little thing you swipe your credit card into.
Homer: The war is over and the future won. Past never even had a chance, man.
Homer: Aw, twenty dollars! I wanted a peanut!
Homer’s Brain: Twenty dollars can buy many peanuts!
Homer: Explain how!
Homer’s Brain: Money can be exchanged for goods and services!
Homer: Woo-hoo!
Marge: Homer, the plant called. They said if you don’t show up tomorrow don’t bother showing up on Monday.
Homer: Woo-hoo. Four-day weekend.
Homer: Kids, you tried your best and you failed miserably. The lesson is, never try.
Homer: If at first you don’t succeed, give up.
Homer: I’m normally not a praying man, but if you’re up there, please save me … Superman.
Marge: This is the worst thing you’ve ever done.
Homer: You say that so often that it lost its meaning.
Bart: Dad, what’s a Muppet?
Homer: Well, it’s not quite a mop, not quite a puppet, but man … (laughs, then pauses) So, to answer you question, I don’t know.
Homer: [Meeting Aliens] Please don’t eat me! I have a wife and kids. Eat them!
Homer: We kill Mr. Burns! We kill Mr. Burns! Mr. Burns gonna be mad!
Homer: Operator! Give me the number for 911!
Unless you’re Canadian, you’re not doing anyone any favors by saying “sorry” all the time. New York based artist Yao Xiao takes this a step further in her comics, where she suggests that you say “thank you” instead. The Internet is full of empty promises and terrible art, but this idea is worth paying attention to; see how using “thank you” instead of “sorry” plays out below.
Yao Xiao was born in China but now lives in New York. Many of her comics are autobiographical, and she describes herself as an “enthusiast for queer fashion, vintage cabaret, collecting odd objects, and absurd science fiction with a flair of whimsy.” The rest of Xiao’s work is quite different from the comics below, so be sure to check out her website!
You think man can destroy the planet? What intoxicating vanity. Let me tell you about our planet. Earth is four-and-a-half-billion-years-old. There’s been life on it for nearly that long, 3.8 billion years. Bacteria first; later the first multicellular life, then the first complex creatures in the sea, on the land. Then finally the great sweeping ages of animals, the amphibians, the dinosaurs, at last the mammals, each one enduring millions on millions of years, great dynasties of creatures rising, flourishing, dying away — all this against a background of continuous and violent upheaval. Mountain ranges thrust up, eroded away, cometary impacts, volcano eruptions, oceans rising and falling, whole continents moving, an endless, constant, violent change, colliding, buckling to make mountains over millions of years. Earth has survived everything in its time. It will certainly survive us. If all the nuclear weapons in the world went off at once and all the plants, all the animals died and the earth was sizzling hot for a hundred thousand years, life would survive, somewhere: under the soil, frozen in Arctic ice. Sooner or later, when the planet was no longer inhospitable, life would spread again. The evolutionary process would begin again. It might take a few billion years for life to regain its present variety. Of course, it would be very different from what it is now, but the earth would survive our folly, only we would not. If the ozone layer gets thinner, ultraviolet radiation sears the earth, so what? Ultraviolet radiation is good for life. It’s powerful energy. It promotes mutation, change. Many forms of life will thrive with more UV radiation. Many others will die out. Do you think this is the first time that’s happened? Think about oxygen. Necessary for life now, but oxygen is actually a metabolic poison, a corrosive glass, like fluorine. When oxygen was first produced as a waste product by certain plant cells some three billion years ago, it created a crisis for all other life on earth. Those plants were polluting the environment, exhaling a lethal gas. Earth eventually had an atmosphere incompatible with life. Nevertheless, life on earth took care of itself. In the thinking of the human being a hundred years is a long time. A hundred years ago we didn’t have cars, airplanes, computers or vaccines. It was a whole different world, but to the earth, a hundred years is nothing. A million years is nothing. This planet lives and breathes on a much vaster scale. We can’t imagine its slow and powerful rhythms, and we haven’t got the humility to try. We’ve been residents here for the blink of an eye. If we’re gone tomorrow, the earth will not miss us.
If you don’t know history, then you don’t know anything. You are a leaf that doesn’t know it is part of a tree.
If I were to say, “God, why me?” about the bad things, then I should have said, “God, why me?” about the good things that happened in my life.
-Arthur Ashe-
Arthur Ashe adalah seorang petenis kulit hitam legendaris asal Amerika. Prestasinya sungguh luar biasa. Tiga gelar Grand Slam, turnamen paling bergengsi tersimpan di lemari kacanya. Gelar itu adalah US Open (1968), Australian Open (1970), dan Wimbledon (1975). Sebuah prestasi yang sulit diraih pada masa itu.
Selesai berkarir di lapangan, dia pun gantung raket. Namun dia bernasib kurang bagus. Pada 1979, ia terkena serangan jantung. Dokter memutuskan ia harus operasi Bypass jantung. Dua kali operasi dijalankan agar Ashe sembuh.
Tapi bukan sembuh yang didapat. Operasi ternyata membawa bencana lain. Dari transfusi darah, dia mendapat virus yang sekarang dikenal dengan nama HIV pada 1983. Pada masa itu, pengawasan terhadap berjangkitnya virus ini memang masih rendah.
Kenyataan pahit ini ia sembunyikan kepada publik. Sampai akhirnya, pada April 1992, koran terkemuka USA Today menurunkan laporannya mengenai kondisi kesehatannya. Sontak publik pun tercengang. Kebanyakan dari mereka menyayangkan tragedi yang menimpa petenis yang rendah hati itu.
Sepucuk surat dari seorang pengagumnya pun sampai ke tangannya. Penggemar itu menyatakan keprihatinannya. Dalam suratnya, sang penggemar bertanya, “Why did God have to select you for such a bad disease?” Pertanyaan yang biasa saja, tapi sungguh dalam, “Mengapa Tuhan memilihmu untuk menderita penyakit ini?”
Arthur menjawab, “Begini. Di dunia ini ada 50 juta anak yang ingin bermain tenis, diantaranya 5 juta orang yang bisa belajar bermain tenis, 500 ribu orang belajar menjadi pemain tenis profesional, 50 ribu orang datang ke arena untuk bertanding, 5000 orang mencapai turnamen Grand Slam, 50 orang berhasil sampai ke Wimbledon, 4 orang di semifinal, 2 orang di final. Dan ketika saya mengangkat trofi Wimbledon, saya tidak pernah bertanya kepada Tuhan, ‘Mengapa saya yang menjadi juara?’ Jadi ketika saya dalam kesakitan, tidak seharusnya juga saya bertanya kepada Tuhan, ‘Mengapa saya?'”
Pada 6 Februari 1993, Ashe mengembuskan napas terakhirnya. Dua bulan sebelum mengembuskan napas terakhirnya, Ashe mendirikan Arthur Ashe Institute for Urban Health. Dan beberapa minggu sebelum ia wafat, Ashe masih menyempatkan diri menulis memoarnya yang berjudul “Days of Grace“.
