Narrative Text: The Three Snake-Leaves

There was once on a time a poor man, who could no longer support his only son. Then said the son, “Dear father, things go so badly with us that I am a burden to you. I would rather go away and see how I can earn my bread.” So the father gave him his blessing, and with great sorrow took leave of him. At this time the King of a mighty empire was at war, and the youth took service with him, and with him went out to fight. And when he came before the enemy, there was a battle, and great danger, and it rained shot until his comrades fell on all sides, and when the leader also was killed, those left were about to take flight, but the youth stepped forth, spoke boldly to them, and cried, “We will not let our fatherland be ruined!” Then the others followed him, and he pressed on and conquered the enemy. When the King heard that he owed the victory to him alone, he raised him above all the others, gave him great treasures, and made him the first in the kingdom.

The King had a daughter who was very beautiful, but she was also very strange. She had made a vow to take no one as her lord and husband who did not promise to let himself be buried alive with her if she died first. “If he loves me with all his heart,” said she, “of what use will life be to him afterwards?” On her side she would do the same, and if he died first, would go down to the grave with him. This strange oath had up to this time frightened away all wooers, but the youth became so charmed with her beauty that he cared for nothing, but asked her father for her. “But dost thou know what thou must promise?” said the King. “I must be buried with her,” he replied, “if I outlive her, but my love is so great that I do not mind the danger.” Then the King consented, and the wedding was solemnized with great splendour.

They lived now for a while happy and contented with each other, and then it befell that the young Queen was attacked by a severe illness, and no physician could save her. And as she lay there dead, the young King remembered what he had been obliged to promise, and was horrified at having to lie down alive in the grave, but there was no escape. The King had placed sentries at all the gates, and it was not possible to avoid his fate. When the day came when the corpse was to be buried, he was taken down into the royal vault with it and then the door was shut and bolted.

Near the coffin stood a table on which were four candles, four loaves of bread, and four bottles of wine, and when this provision came to an end, he would have to die of hunger. And now he sat there full of pain and grief, ate every day only a little piece of bread, drank only a mouthful of wine, and nevertheless saw death daily drawing nearer. Whilst he thus gazed before him, he saw a snake creep out of a corner of the vault and approach the dead body. And as he thought it came to gnaw at it, he drew his sword and said, “As long as I live, thou shalt not touch her,” and hewed the snake in three pieces. After a time a second snake crept out of the hole, and when it saw the other lying dead and cut in pieces, it went back, but soon came again with three green leaves in its mouth. Then it took the three pieces of the snake, laid them together, as they ought to go, and placed one of the leaves on each wound. Immediately the severed parts joined themselves together, the snake moved, and became alive again, and both of them hastened away together. The leaves were left lying on the ground, and a desire came into the mind of the unhappy man who had been watching all this, to know if the wondrous power of the leaves which had brought the snake to life again, could not likewise be of service to a human being. So he picked up the leaves and laid one of them on the mouth of his dead wife, and the two others on her eyes. And hardly had he done this than the blood stirred in her veins, rose into her pale face, and coloured it again. Then she drew breath, opened her eyes, and said, “Ah, God, where am I?”

“Thou art with me, dear wife,” he answered, and told her how everything had happened, and how he had brought her back again to life. Then he gave her some wine and bread, and when she had regained her strength, he raised her up and they went to the door and knocked, and called so loudly that the sentries heard it, and told the King. The King came down himself and opened the door, and there he found both strong and well, and rejoiced with them that now all sorrow was over. The young King, however, took the three snake-leaves with him, gave them to a servant and said, “Keep them for me carefully, and carry them constantly about thee; who knows in what trouble they may yet be of service to us!”

A change had, however, taken place in his wife; after she had been restored to life, it seemed as if all love for her husband had gone out of her heart. After some time, when he wanted to make a voyage over the sea, to visit his old father, and they had gone on board a ship, she forgot the great love and fidelity which he had shown her, and which had been the means of rescuing her from death, and conceived a wicked inclination for the skipper. And once when the young King lay there asleep, she called in the skipper and seized the sleeper by the head, and the skipper took him by the feet, and thus they threw him down into the sea. When the shameful deed was done, she said, “Now let us return home, and say that he died on the way. I will extol and praise thee so to my father that he will marry me to thee, and make thee the heir to his crown.” But the faithful servant who had seen all that they did, unseen by them, unfastened a little boat from the ship, got into it, sailed after his master, and let the traitors go on their way. He fished up the dead body, and by the help of the three snake-leaves which he carried about with him, and laid on the eyes and mouth, he fortunately brought the young King back to life.

They both rowed with all their strength day and night, and their little boat flew so swiftly that they reached the old King before the others did. He was astonished when he saw them come alone, and asked what had happened to them. When he learnt the wickedness of his daughter he said, “I cannot believe that she has behaved so ill, but the truth will soon come to light,” and bade both go into a secret chamber and keep themselves hidden from every one. Soon afterwards the great ship came sailing in, and the godless woman appeared before her father with a troubled countenance. He said, “Why dost thou come back alone? Where is thy husband?”

“Ah, dear father,” she replied, “I come home again in great grief; during the voyage, my husband became suddenly ill and died, and if the good skipper had not given me his help, it would have gone ill with me. He was present at his death, and can tell you all.” The King said, “I will make the dead alive again,” and opened the chamber, and bade the two come out. When the woman saw her husband, she was thunderstruck, and fell on her knees and begged for mercy. The King said, “There is no mercy. He was ready to die with thee and restored thee to life again, but thou hast murdered him in his sleep, and shalt receive the reward that thou deservest.” Then she was placed with her accomplice in a ship which had been pierced with holes, and sent out to sea, where they soon sank amid the waves.

What is chemistry

Chemistry is defined as a natural science that studies the composition, structure, and properties of matter, as well as the changes it undergoes and energy accompanying the process.(Johari, et al, 2006)
Kimia didefinisikan sebagai ilmu pengetahuan alam yang mempelajari komposisi, struktur, dan sifat-sifat zat, serta perubahan yang terjadi dan energi yang menyertai prosesnya. (terjemahan-Intan)

Zat disediakan oleh alam sebagai sumber daya alam atau natural resources. Natural resources dapat renewable (dapat diperbarui) atau nonrenewable(tidak dapat diperbarui).
Pengetahuan kimia membantu kita untuk mencari zat alternatif bagi at-zat yang tidak dapat diperbarui atau dengan melestarikan zat-zat yang tidak dapat diperbarui.

Perkembangan Sains

Sifat Relatif (Nisbi) dari Konsep Sains

Sains berasal dari bahasa latin scientia yang artinya ilmu pengetahuan. Pengetahuan adalah semua yang diketahui oleh seseorang tentang suatu obyek.

Pengetahuan bukan sekedar tahu, tetapi mengetahui dengan benar. Namun criteria kebenaran tidaklah mutlak. Sehingga bila kita lihat dari perkembangan ilmu pengetahuan akan terlihat bahwa kebenaran itu telah berubah-ubah sesuai dengan zaman atau waktu.

Ketika Galileo Galilei menyatakan bahwa bumi adalah bulat dan menglilingi matahari, para penguasa pada saat itu mengenggap ajaran Galileo adalah pelajaran yang menyesatkan. Tetapi beberapa abad kemudian ternyata hal iotu diketahui benar. Sehingga dapat kita katakana bahwa kebenaran sains bersifat relative (tidak mutlak.

Juga tetang teori evolusi Darwin sampai sekarang belum ada bukti mutlak kebenarannya dan bukti mutlak salahnya.

Report Text : LESSER SLOW LORRIS


Lesser Slow Lorris (Nyticebus Pygmaseus) is a mammal which can clamps onto branches for long periods of time. To help it do this, the Loris has a network of blood vessels, called rate mirabilis in its forearms and shanks.

It is a small mammal which is 7-10 inches long (175-250 mm) and can weigh as much as 12 ounces or 340 grams. Being nocturnal the Loris has large round eyes. The Loris has no tail but has broad grasping feet. On its second toe it has a sharp claw. It also has an enlarged thumb and a reduced index finger.

The Lesser Slow Lorris is a plump animal with soft, thick fur ranging in color from light brownish-grey to deep reddish-brown with a dark stripe down the back and neck. It has a long snout with corn-like front teeth which are used in grooming.

It is found in Southern Asia, Vietnam, Borneo, and Sumatera. As it is tree-living, it is restricted to tropical rain forests. The diet of the Loris is made up of fruit and leaves, tender shoots, insects, birds, small mammals and reptiles. It is nocturnal and sleeps by day rolled up in a ball.

The Lorris a solitary animal.It is a very slow but deliberate climber. An interesting fact about the Lesser Slow Lorris is that it has a single-note whistle.

Katalis Baru Tiru Fotosintesis, Pasok Rumah Dengan Energi Listrik Dan Hidrogen Dari Sebotol Air


Sun Catalytix, sebuah perusahaan yang didirikan oleh Dan Nocera, yang juga seorang ahli kimia dari Massachusset Institute of Technology (MIT), berhasil membuat prototip yang berfungsi untuk mengubah sebotol air menjadi energi listrik yang cukup bagi rata-rata satu rumah di Amerika Serikat atau sekitar 30 kWh per hari.

Prinsipnya memang tidak jauh dari elektrolisa. Hanya saja Nocera menggunakan katalis buatannya yang terbuat dari kobalt fosfat, dan memanfaatkan listrik dari panel-panel surya seluas 30 meter persegi. ''Hampir semua energi matahari disimpan dalam penguraian air,'' jelas Nocera pada acara inaugurasi ARPA-E (Advanced Research Projects Agency-Energy) awal Maret lalu. ARPA-E sendiri merupakan lembaga yang berdiri di bawah Departemen Energi Amerika Serikat yang bertugas untuk mendanai proyek-proyek riset berteknologi tinggi yang juga beresiko dan membutuhkan biaya tinggi.

Nocera memang membuat prototip yang meniru prinsip kerja fotosintesis untuk digunakan sebagai media penyimpan energi surya skala besar. Menurut Nocera, sistem yang dikembangkannya bisa bekerja pada suhu dan tekanan ruang, tanpa kemungkinan terjadi korosi dalam segelas air. Bahkan tidak diperlukan air murni untuk menghasilkan listrik. Prototip yang dibuat Nocera hanya menggunakan air dari sungai Charles River di Boston sejak mulai pertama hingga saat ini dioperasikan.

Nocera juga menambahkan, jika dibandingkan dengan peng-elektrolisa komersial yang saat ini seharga 12.000 dolar AS per kiloWatt, prototip yang dikembangkannya jauh lebih murah. Menurutnya dengan harga setinggi itu, maka perangkat komersial yang ada tidak akan memberikan kontribusi dalam ketahanan energi AS atau bahkan untuk masyarakat miskin di negara-negara miskin dan berkembang. ''Sudah saatnya kita berhenti membuat sistem energi yang besar untuk keperluan banyak orang dan mulai membuat sistem yang lebih kecil untuk kemudian diproduksi massal,'' imbuhnya.

Jika prototip yang dikembangkan Sun Catalytix bisa berunjuk kerja seperti yang direncanakan dan telah mencapai kematangan teknologinya, maka setiap rumah akan memiliki pembangkit listrik dan stasiun pengisian bahan bakar sendiri. ''Akhirnya Anda tidak memerlukan energi lagi dari orang lain karena Anda sudah menggunakan matahari di rumah Anda sendiri,'' tegas Nocera.
