Ten Pakistani Scientists who Made a Difference in the World

Image
Mostly, Pakistani students are taught about inventions and discoveries of Muslims and they list hundreds and thousands year old inventions by Muslims. But one important fact needs to be highlighted that Pakistani scientists, too, have a great contribution in where the world is standing today. There are hundreds of capable scientists which have worked on prestigious scientific missions and many of them even have invented numerous things in their disciplines.   This list of greatest Pakistani scientists prove that Pakistan is not far behind anyone in development of today and has a contribution in the modern world. Even though resources in the country are minimal, yet these brilliant minds were stronger enough to take over the circumstances. (Following number-list is just for convenience, and it is not meant to rank them on certain positions.) 1) Dr. Naweed Syed He is a Pakistani Canadian scientist. He is the first scientist who managed to 'connect brain cells...

Chinese scientists a step closer to developing supersonic submarine

Image
The new ‘supercavitation’ methodology could see the vehicles travel at rates up to 3,600 mph underwater, being able to make the trip from Shanghai to San Francisco in about two hours. BY  DAVID HARDING    NEW YORK DAILY NEWS   Sunday, August 24, 2014, 1:54 PM Chinese scientists are working on creating a submarine that would be able to travel at speeds up to 3,600 mph. Previous Next   Enlarge It is a   distance of more than 6,100 miles. But a team of Chinese scientists claim to have moved closer to developing a supersonic submarine, which could complete the journey from Shanghai to San Francisco in less than two hours. Researchers from the Harbin Institute of Technology say they have developed a way to make a submarine — or torpedo — to travel at extremely fast speeds underwater. Li Fengchen said his team of scientists can now create the complicated air "bubble" required for fast travel undersea. This bu...

Australian scientists are a step closer to converting sunlight and water into fuel

Image
Scientists have replicated a crucial photosynthetic reaction for the first time, taking them a step closer to creating sustainable, cheap fuel from water and sunlight - just like plants do. FIONA MACDONALD    WEDNESDAY, 27 AUGUST 2014 Image:  Australian National University Plants use  photosynthesis  to turn water, carbon dioxide and sunlight into oxygen and the energy they need to power their systems. And for decades scientists have been trying to replicate this reaction in order to create biological systems that can produce cheap, clean hydrogen fuel. Now, for the first time ever, scientists from the Australian National University in Canberra, Australia, have managed to modify a naturally occurring protein, and use it to capture energy from sunlight, a key step in photosynthesis. Their results have been published in  BBA Bioenergetics . “Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and ...

Scientists ‘freeze’ light for an entire minute

Image
In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute. It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory. And the longer that light can be held, the better as far as computation is concerned. Accordingly, it could allow for more  secure quantum communications  over longer distances. Needless to say, halting light is not easy — you can't just put in the freezer. Light is electromagnetic radiation that moves at 300 million meters per second. Over the course of a one minute span, it can travel about 11 million miles (18 million km), or 20 round trips to the moon. So it's a rath...
