چار پرندے جو ذبح ہو کر دوبارہ زندہ ہو گئے

چار پرندے جو ذبح ہو کر دوبارہ زندہ ہو گئے
(Four birds were sacrificed and resurrected)
حضرت ابراہیم خلیل اللہ علیہ السلام نے ایک مرتبہ خداوند قدوس کے دربار میں یہ عرض کیا کہ یا اللہ تو مجھے دکھا دے کہ تو مردوں کو کس طرح زندہ فرمائے گا؟ تو اللہ تعالیٰ نے فرمایا کہ اے ابراہیم کیا اس پر تمہارا ایمان نہیں ہے، تو آپ نے عرض کیا کہ کیوں نہیں؟ میں اس پر ایمان تو رکھتا ہوں لیکن میری تمنا یہ ہے کہ اس منظر کو اپنی آنکھوں سے دیکھ لوں تاکہ میرے دل کو قرار آجائے تو اللہ تعالیٰ نے فرمایا کہ تم چار پرندوں کو پالو اور ان کو خوب کھلا پلا کر اچھی طرح ہلا لو پھر تم انہیں ذبح کر کے اور ان کا قیمہ بنا کر اپنے گرد و نواح کے چند پہاڑوں پر تھوڑا تھوڑا گوشت رکھ دو۔ پھر ان پرندوں کو پکارو تو وہ پرندے زندہ ہو کر دوڑتے ہوئے تمہارے پاس آجائیں گے اور تم مردوں کے زندہ ہونے

HOW IS A PLANE PROTECTED FROM LIGHTNING STRIKES?

HOW IS A PLANE PROTECTED FROM LIGHTNING STRIKES? 

Since the outer skin of most airplanes is primarily aluminum, which is a very good conductor of electricity; the secret to safe lightning hits is to allow the current to flow through the skin from the point of impact to some other point without interruption or diversion to the interior of the aircraft.

How a Jet Engine Works

How a Jet Engine Works

A jet engine can be divided into several distinct sections: intake, compressor, diffuser, combustion chamber, turbine, and exhaust. These sections are much like the different cycles in a four-stroke reciprocating engine: intake, compression, power and exhaust. In a four-stroke engine a fuel/air mixture is is brought into the engine (intake), compressed (compression), and finally ignited and pushed out the exhaust (power and exhaust). In it's most basic form, a jet engine works in much the same way.

HOW SOLAR PANELS 
Convert The Sun’s Energy From Atoms In Silicon

The light from the sun contains energy. These particles of (light) energy are called ‘photons’.

HOW TOUCH SCREEN WORKS

HOW TOUCH SCREEN WORKS!

Touch screens have totally changed the way we use mobile phones. But how does wiping your finger on a glass screen make things happen inside your phone?


Touch screens on phones and tablets really have the X factor. Being able to text, phone or film something just by swiping your finger on glass almost makes up for all those other failed sci-fi promises of the 60s.
