Majlis Konvokesyen Universiti Kolej Antarabangsa PICOMS, MAIWP (Siri I)

Di awal pagi, seiring dengan kedatangan anak dhuha, saya bergerak meninggalkan Cyberjaya tujuan Majlis Konvokesyen PICOMS kali ke 11. Seramai 1,111 graduan akan bergraduan bagi sesi 2019/2020.

Majlis telah disempurnakan oleh YB Datuk Dr Zulkifli Al-Bakri, Menteri di JPM (Bhg Agama). Tahniah semua graduan.

Ini kali pertama saya menghadiri majlis konvokesyen PICOMS & ini juga kali pertama air mata berjejeran turun atas pelitup muka saya. Terdapat tiga graduan yang diberikan anugerah secara anumerta kerana mereka sudah kembali ke Rahmatullah. Sudah pasti ibu bapa mereka yang berada dalam dewan akan menitis air mata mereka. Saya melihat mereka naik ke atas pantas dengan linangan air mata.

Kisah tragedi ini diungkap sebagai naratif sedih oleh Dekan, Fakulti Kesihatan. Saya telah meminta ucapan beliau untuk saya upload dalam media sosial saya. Ini sebahagian dpd teks ucapan naratif sedih.

"Cendarawasih si burung pintar
Terbang tunduk mencari sarang
Manis berkasih cuma sebentar
Datang yang elok dia menghilang

Tiada kata yang mampu diungkapkan bagi menggambarkan kedukaan seluruh warga Fakulti Farmasi dan seterusnya warga PICOMs di atas pemergian serentak tiga anak dari jurusan Diploma Farmasi. Pelajar2 yang kami sayangi ini iaitu Sharifah Farisha Bt Syed Fathi, Ayuni Syazwanie Bt. Sabri dan Nor Adilah Bt. Mohd Safwan telah kembali ke Rahmatullah pada tanggal 17 dan 18 September 2020 akibat keracunan gas karbon monoksida.

Sejarah hitam ini telah terpahat di kala mereka bercuti bersama dan singgah berehat di sebuah stesen minyak di Seberang Jaya sebelum meneruskan perjalanan pulang abadi ke Gurun dan Sg. Petani; percutian terakhir yang mengamit detik hitam.

Aturan Allah yang Maha Esa, Sharifah Farisha telah pergi di lokasi kejadian manakala Ayuni Syazwanie meninggal dunia ketika bertarung nyawa di Hospital Seberang Jaya. Pasangan kembar istimewa Nor Adilah dan Nor Aqilah ketika itu dilaporkan kritikal. Lebih menambah kedukaan kami Nor Adilah yang pada awalnya juga terselamat disahkan meninggal dunia ketika di rawat Unit Rawatan Rapi (ICU), TLDM, Lumut pada 18 September."

Al-Fatihah.

【新文章】為什麼一天有24小時？

我們都知道時鐘走一圈有12個數字，當時針走完兩圈就代表是24小時過去了，是新一天的開始。然而，你又有否想過為什麼是24而不是23或25，又或者不乾脆用10呢？

現代科學裡，時間的國際單位（SI unit）是秒。1秒的長度有精確定義：銫-133（cesium-133）原子基態的超精細結構（hyperfine structure），當進行量子躍遷時釋放的電磁輻射頻率的9,192,631,770個週期的時間長度[1]。秒是七個物理基礎單位之一。

一天24小時可能源自古埃及文明。古埃及的人在一年之間變化的夜空中發現了24顆明亮的星，剛好能夠把整晚分成24等份。由於埃及接近赤道，黑晚長度大約是12個小時，但不要以為一晚只能看見12顆星！由於星星會東升西落因此在埃及的一年中任何時刻，都能看見18顆星（剩下的6顆位置接近太陽因而看不見）。而且，頭尾各3顆星都出現在日出或日落時候，因太陽光的關係而很難看見，因此真正容易看見的只有黑夜中的12顆星。所以，他們把夜間劃分成12等份（注意不是11，只要12顆星放於每份的中央即可），亦按照此習慣把日間分為12等份。

不過在日間看不見星星，古埃及人如何得知時間？原來，他們會在日間使用一種稱為日晷（sundial）的儀器。這是一種把一個「人」字型垂直放在一個圓盤上的儀器，太陽光照射下來，便會在圓盤上投射出陰影，陰影指着的數字就是日間的時間。在晚間，除了使用12顆星之外，也有一種比較可靠的計時方法，就是利用放在特製水桶中的水位高度來顯示出夜間的12等份。

早晚各分為12等份亦有可能來自另一個原因。古埃及人採用的是12進制而非現在我們所使用的10進制。有些歷史研究指出，他們可能習慣用拇指數數目，而其他4隻手指各有3節，因此就等於12了。因此，一天24等份剛好等於兩隻手除了拇指之外的指節數目，所以這亦可能是他們採用24這個數字的原因。

不過在未來，一天可能會有25小時，甚至更久呢！因為月球所引起的潮汐，海水會與地球摩擦，使地球的自轉速度減慢。大約每5萬年地球自轉就會減慢1秒。因此，在大約1億8千萬年以後，我們一天就能有25小時用了！同樣道理，在大約14億年前，地球的自轉比現在快多了，當時一天可是只有18小時呢！原來，一天並不一定就是24小時的啊。

之不過，如果一天被分為24等份，為什麼1小時和1分鐘都卻被分成60等份？這就與古巴比倫人使用60進制有關。對古巴比倫人來說，60是個非常方便的數字，因為它能夠被非常多日常需要用到的數目字除盡：1、2、3、4、5、6、10、12、15、20、30。這對於表達一個數字的分數很有用。

這個習慣被流傳到古希臘。事實上，小時和分鐘被分為60等份的做法，與西方科學和數學之中把角度分為360等份有關。測量地球周長的古希臘科學家埃拉托色尼（Eratosthenes）首先把一個圓形分成60等分。之後喜帕恰斯（Hipparchus）把這定義推廣為360等份。最後，為了量度比1度更小的角度，古希臘人把1度再分為60角分、1角分再分為60角秒。

角分的拉丁文是partes minutae primae，意即「第一分割」，英文譯作first minute，漸漸簡稱成minute，即我們說的角分或分鐘。角秒的拉丁文partes minutae secundae，意思就是「第二分割」，即是second minute，之後就簡稱second，即我們說的角秒或秒。不過直到16世紀末發明機械時鐘之前，普羅大眾基本上都不使用分鐘和秒。

總結來說，「從上而下」把1天分為24小時，是古代天文學和度量衡傳統而來。「從下而上」由定義1秒到60秒為1分鐘、60分鐘為1小時，再反過來把1天的長度定義為24 x 60 x 60 = 86,400 秒，則是現代科學的做法。

Kisah penulis lapar.

Dua tiga hari ni kecoh isu penerbit tak bayar Royalti, alamak? Teruk ke jadi penulis?

Maka saya sebagai penulis 12 buku nak bercerita kisah penulis yang ada waktu kenyang, banyak waktu lapar, dan kadang kadang kebuluran.

Semoga tulisan ini dapat dijadikan pedoman hidup, atau sebagai rujukan, atau batu loncatan, atau batu yang di baling laju ke permukan air lantas dipuji kerana melambung lambung tiga percikan lalu tenggelam dan nobody care.

Nasihat pertama, bagi mereka yang nak jadikan kerjaya menulis ini sepenuh masa: tengoklah siapa penerbit anda, dan siapa kerajaan memerintah zaman tu, jika dapat kerajaan mesra buku, dan penerbit yang telus. Alhamdulillah.

Jika dapat kerjaan yang dalam pembentangan bajet kau search perkataan “buku” tak ada, dan dapat pula penerbit yang tak takut rohnya tergantung di langit kerana berhutang dengan penulis, atau tipu bilangan jualan agar royalty rendah, maka bersiap sedialah untuk rebus buku dan hisap dakwat.

Alkisahnya, awal menulis dulu, buku saya semua direject penerbit, sebab katanya tulisan saya tak sesuai dengan zaman ini.

Tapi saya tak putus asa, buku pertama saya PERMATA YANG HILANG KINI DIJUMPAI, pinjam duit kawan kawan RM10 ribu cetak sendiri.

Alhamdulillah, setahun, habis terjual. Tapi penat dan puas hati sebab dapat bayar hutang namun masa menjual lebih banyak dari masa menulis buku baru, maka saya dah tak nak terbit sendiri.

Maka buku kedua saya, ada Penerbit datang tawarkan, iaitu kompeni TERFAKTAB MEDIA, judulnya KAMAR SUTERA.

Laku keras katanya, buat cetakan baru dengan dua Cover berbeza.

Dengan TERFAKTAB ni, saya buat lima buku, selain KAMAR SUTERA, buku saya berjudul SEMUSIM DI SYURGA (laku hingga ada dua cover) SEMUSIM DI NERAKA (habis di pasaran) dan KISAH HANTU TERAKHIR. (ada 10 bijik lagi,)

Royalti Alhamdulillah, di bayar ikut bilangan buku dijual, setahun sekali, atau setahun dua kali, jika saya beli sendiri ada diskaun 50%, dan pernah kompeni ini taja saya dan isteri melancong ke Bandung.

Dapatlan naik gunung berapi dan main indoor game di transbandung!

Namun, pelango tak selalunya berbelang. Kompeni ada masalah, dan dah tutup, lalu Karya saya di serap ke WRITE and BRAVE kompeni baru tapi Nampak gaya tiada cetakan baru untuk karya saya. Hu huh u.

Baik, Syarikat kedua yang lamar saya adalah KARANGKRAF, dijadikan penulis indie pertama bawah penerbitan BUKU POJOK, di Karang Kraf, saya tulis buku KISAH LAKI BINI yang mendapat best seller, jualan sampai lima angka, dapat naik pentas bersama Ramlee Awang Murshid terima Anugerah. Alhamdulillah. Pernah juga di bawa Karangkraf jalan -jalan ke Sawarak dan Sabah.

Selain KISAH LAKI BINI, saya menulis KISAH ANAK BINI, SATU, dan MENGETEH DI KUBUR AYAH.

Sistem Royalti di Karangraf sangat tersusun, jualan buku dinyatakan, dan Royalti akan di bayar ikut jadual. Masih mendapat royalty walau dah tak banyak, faham factor ekonomi, dan Hingga sekarang buku saya under KarangKraf masih dijual diseluruh negara, boleh tegur jika jumpa, dan jika tak jumpa boleh mesej saya untuk beli. He he

Syarikat ketiga yang lamar saya, adalah TARBIAH SENTAP, dan saya menulis buku MENANGKAP DAJJAL DI WAKTU DHUHA.

Cetakan pertama 10 ribu unit, dan habis! Saya rasa the best penerbit forever dari segi royalti dan kontrak adalah TARBIAH SENTAP, jualan buku dijual kepada penulis sangat tinggi diskaun, dan rasanya Royalti paling tinggi saya terima adalah dari Kompeni ini, di bayar Royalti dulu, walau buku tak habis dijual. Perghhh Dahsyat! Kontrat habis tempoh pun sedap termanya!

Zaman tu zaman kaya lah jugak, zaman penulis kenyang!

Kemudian saya di lamar oleh Dubook, saya tulis AKU ALMOND LONDON DAN GAY, dan saya akui pernah terima royalty sekali, lepas tu membisu, saya follow up balik (dan lepas betahun tahun membisu) dua tiga hari lepas, mereka kata dalam proses, saya tunggu sahajalah. Semoga mereka Berjaya dengan janji terkini mereka, Amin.

Terkini, saya dilamar PTS bawah penerbitan Puteh Press, dengan karya KERANA DIA ANAK SYURGA, baru setahun buku itu, Alhamdulillah dah dapat royalty pertama dan mana mana kedai buku saya pergi Nampak jer buku saya ada atas rak. Rezeki anak OKU Autisme saya ni, Alhamdulillah.

Dan sisi gelap, bukan semua karya saya diterima, KISAH PEMBUNUH DAN TAKDIR, masih diperam oleh sebuah penerbitan, TEKA TEKI ISLAMIK, ditolak, dan terbaru saya buat KISAH MUALAF BERCAKAP DENGAN KUCING dan sedang tunggu jawapan dari penerbit baru anak muda, kita tengok hasilnya.

Jadi jika bertanya, kenyangkah jadi penulis?

Untuk saya jika saya menulis sahaja, maka saya akan kelaparan, sebab royalty ni dibayar setahun sekali. Dah dapat terus bayar hutang.

Zaman mewah adalah zaman baucer buku, memang penerbitan tumbuh macam cendawan lepas hujan.

Jadi saya bukan full time menulis, buat macam macam kerja jugak, jual tanjak, tolong kawan jual ebook, buat kursus penulisan, buat homestay (tak menjadi dah tutup), dan macam macam lah, tapi saya tetap menulis sebab seronok menulis.

Pendek kata, Nak jadi kaya dengan menulis ni belum rezeki saya, tapi Alhamdulillah bersyukur dengan segala nikmat.

Jadi pesanan saya kepada semua penerbit yang ada hutang dengan penulis, bayarlah, sebab si mati syahid, patut masuk syurga tanpa hisab, namun rohnya tergantung sebab ada hutang, maka apatah lagi kita semua yang banyak dosa,

ingatlah roh yang tak boleh dipegang... Nampak macam boleh lari sambil terbang tapi kuasa Tuhan, mampu di gantung roh kita, mana kau nak lari wahai roh? Adohai..

Akhir kata, terima kasih kepada semua penerbit yang sudi terbitkan buku saya, Terima kasih yang bayar royalty buku saya,

Juga Terima kasih tak terhingga kepada yang sudi beli buku saya, dan kepada yang nak beli lagi, stok yang ada, Semusim di Syurga, Hantu Terakhir, Kisah LAki Bini, KIsah Anak Bini, Mengeteh di Kubur ayah, Kerana dia Anak Syurga. http://www.wasap.my/60199117163 Nak Beli tanjak pun boleh jugak, hehehe.

Last! Semua ini akan menjadi kenangan, izikan buku aku terselit di almari rumahmu, memerhati kehidupanmu dan tiba tiba kau menoleh melihat bukuku, sambil masing masing: kagum dari jauh.

Woha!
