Saintis buktikan Nabi Musa belah laut

LAKARAN artis menunjukkan angin kuat dari timur telah menyebabkan air lagun (kiri) dan sungai (kanan) 'berpusing' dan membentuk dinding air dekat Laut Merah.



BOULDER, Amerika Syarikat (AS) - Saintis-saintis di AS membuktikan kebenaran kisah Nabi Musa membelah laut seperti yang diceritakan dalam kitab suci al-Quran dan Injil, lapor sebuah akhbar semalam.

Satu kajian oleh sepasukan penyelidik yang diketuai saintis Carl Drews dari Pusat Penyelidikan Atmosfera Nasional di sini, mendapati fenomena itu tidak bercanggah dengan hukum fizik.

Kitab al-Quran menceritakan bahawa Nabi Musa membelah laut dengan menghentakkan tongkatnya ke tanah semasa baginda dan kaum Bani Israel terperangkap di antara pasukan tentera Firaun yang sedang mara dan laut di hadapan mereka.

Kumpulan saintis itu yang mengkaji beberapa peta kuno Delta Sungai Nil mendapati laut terbelah itu merujuk kepada sebuah lagun yang kini dikenali sebagai Tasik Tanis di selatan Laut Mediterranean dekat Laut Merah dan satu cawangan Sungai Nil.

Kini, dengan menggunakan simulasi komputer, saintis-saintis itu menunjukkan bahawa laut berkenaan terbelah dua melalui proses tiupan angin kencang yang dikenali sebagai angin timur bertiup selaju 100.8 kilometer sejam (km/j) selama 12 jam menyebabkan aliran air sungai dan lagun itu berpusing balik lalu membentuk seperti dinding air.

Satu model lautan komputer kemudian digunakan sebagai simulasi bagi melihat kesan angin yang bertiup semalamam ke atas air sedalam beberapa meter itu.

Selama empat jam, tiupan angin tersebut menghasilkan jambatan darat sepanjang 3.2 kilometer (km) dan selebar 4.8km.
Sejurus selepas angin timur reda, air lagun dan sungai itu kembali mengalir ke tempat asal seperti ombak tsunami.
Hasil kajian saintis berkenaan disiarkan di Internet oleh Jurnal Public Library of Science ONE. - Agensi



leh explain lagi tak ikut hukum fizik

baru baca paper pasal benda ni ari ni, menarik , ada kena mengena dengan fluid mechanics rasanya ...emmm bab boundary layer , lapisan sempadan .. apa kan daya x larat nak fikir skrg..letih sgt after long tiring journey

btw some basic definition;

boundary layer - the layer of slower flow of a fluid past a surface

1. hmm.. maybe principle of bernoulli's also involve, high wind velocity , low pressure on the sea water surface , atmosphere pressure 'move' the water aside , (no wind blowing side) , and keep doing that until it reach the seamud?

2. let say for 1 hour of high speed wind blown at that particular area will reduce certain high water, and it consitently keep blowing at that particular area and cause reduction further and further.

3. can do a simple experiment here, a straw & a bowl of water .. blow through that straw on the surface of water in that  bowl.. and the wind blowing pattern must be inline/parallel with the water surface , see what happened? i haven't tried this yet , just some hypothesis .

and how do i relate it with boundary layer?

1. wind blowing at certain speed.
2. and the water wall should also 'move' with the same speed, the further side (from the wind should be static)  , and if it so why the water wall not moving anywhere? i GUESS , we should also consider on the vorticity effect.

too complicated ... but hopefully what I'd suggested could make sense.

bernoulli's + boundary layer + vorticity = miracle!

saya pn berfikir begitu

bernoulli principle ada benarnya

it could be happened provided that the velocity wind was too strong
to give such higher force to make the "lagun" appeared


halaju angin yg tinggi---> memberikan tekanan di sekitar atmosfera rendah
maka, bila tekanan udara rendah, perbezaan tekanan menyebabkan air berpintal membentuk lagun spt yg dinyatakn animaniac

  

Persamaan di atas :

komponen yg dipengaruhi: tekanan sekitar, p ;  ketinggian bendalir (z) ; halaju bendalir (v)

persoalannya, klu ikut gmbr di atas, aliran ombak ke kanan manakala halaju angin ke arah utara...
shouldn't the path be on the northwest ? ikut hukum vektor ....

i guess the above pic is only an illustration , actually we can simulate using any CFD software to see if the 'sea' really separated .. seriously dauswq lot of parameter need to be considered (and that explained why the writer can get his Master Degree by just doing research on this?) and i'm kinda pissed off they don't make  it public
