Life Beyond Code

In Physics , Universe is divided into two categories

  • Quantum World
  • Microscopic World

String Theory combines both into ‘The Theory of Everything’

The Universe is made of two group of tiny particles

  • Fermions
  • Bosons

Fermions are all Observable matter while Bosons transmits the four known forces of nature i-e Electromagnetic, gravitational, Strong Nuclear and Weak Nuclear.

Scientists combined all these forces except gravitational (as its weaker that others) into a standard Model. It is the most accurate scientific theory ever devised.

Why String Theory?

The standard model can not describe the centre of blackholes. It also can not predict the resultsof an experiment. String theory is an attemp to fix these problems. String Theory unifies all matter and forces by replacing particles with ‘Vibrating Strings’

For Consistancy , String theory needs six extra dimensions along with our four standard dimensions (three for space and one for time).

Most versions of String Theory require Super-Symmetry ( For every particle of matter there must be corresponding force particle).

 

It seems a dreamy thing….

real dream…. One question comes to mind

IS THIS REAL?  ….

Flight 501, which took place on June 4, 1996, was the first test flight of the European Ariane 5 expendable launch system. It was not successful. Due to a malfunction in the control software the rocket veered off its flight path 37 seconds after launch. It was torn apart by high aerodynamic forces caused by excess change of attitude commanded by the onboard computer.

The breakup caused the loss of the payload: four Cluster mission spacecraft, resulting in a loss of more than US$370 million[1].

It is one of the most famous computer bugs in history.

CAUSE OF THE FAILURE

The failure of the Ariane 501 was caused by the complete loss of guidance and attitude information 37 seconds after start of the main engine ignition sequence (30 seconds after lift- off). This loss of information was due to specification and design errors in the software of the inertial reference system.

The extensive reviews and tests carried out during the Ariane 5 Development Programme did not include adequate analysis and testing of the inertial reference system or of the complete flight control system, which could have detected the potential failure.

Lance Armstrong (born Lance Edward Gunderson on September 18, 1971) is a retired American professional road racing cyclist. He won the Tour de France—cycling’s most prestigious race—seven consecutive times, from 1999 to 2005. In doing so, he beat the previous records of five wins by Miguel Indurain (consecutive) and Bernard Hinault, Eddy Merckx and Jacques Anquetil, (all non consecutive). He accomplished this after undergoing brain and testicular surgery, and extensive chemotherapy, to treat testicular cancer that metastasized to his brain and lungs in 1996. Doping allegations dogged Armstrong throughout his career, but he has consistently denied ever taking performance enhancing substances.

His doctors told him that he had less than a 50% chance of living. After his recovery, one of his doctors told him that his actual odds of living had been considered to be smaller, around 3%, and that he had been given the estimate primarily to give him hope. Three years later, after much recuperation and the loss of his left testicle, he went on to win his first Tour de France title.

One of his reknowned quote: Anything is possible. You can be told that you have a 90-percent chance or a 50-percent chance or a 1-percent chance, but you have to believe, and you have to fight.

MNP (Mobile Number Portability) has been launched on 23 March across Pakistan . But what is it and how it works?

Let me answer a few questions. 

So what is Mobile Number Portability?
It is the ability to move from your current Network Operator to another
and still keep your complete cell number (including the 4-digit prefix
such as 0345).

What is ‘porting’?
The actual transferring of your phone number and services from one Network Operator to another.

Port out : Change your subscription from your current Network Operator and move to another.
Port in
: Opposite of Port out.

what number can be ported?
All MSISDNs of all six operators:

  • Mobilink (0300, 0301, 0302, 0306)
  • Ufone (0333, 0334)
  • Telenor (0345, 0346,0344)
  • Warid (0321, 0322)
  • Paktel (0303)
  • InstaPhone (0320)

What does Donor mean?
If you are porting, the Donor is your current Network Operator.

What does Recipient mean?
If you are porting, the Recipient is the Network Operator to whom you wish to port.

How often can I port?
You can request a port only once in 60 days from the date of a successful
porting. After 60 days a new port can be requested, but remember that
if you are a contract subscriber that you will always be responsible
for the outstanding balance on your subscriber contract, so frequent
porting could become quite costly.

What papers does a customer need to fill out?
Depending on whether a customer is a prepaid or postpaid customer, the following
will need to be presented to the Recipient Network Operator:

  • Completed application form
  • A written request on company letterhead (for corporate customers)
  • CNIC Copy
  • Your actual SIM

How long does porting take?
It takes 4 working days to port a number, provided you have no
obligation/liability on your existing cellular network. Your
subscription will remain active during these 4 days except for some
brief interruption in services (10-15 mins) when actual porting occurs.

When will the actual activation or deactivation take place?
Actual Deactivation at the Donor’s end will take place on the 4th day. As soon
as the Donor Operator terminates and sends confirmation message to
Recipient Operator, Recipient Operator immediately activates the
number. In response Recipient Operator will also send a message to
Donor Operator and Other Operators about successful Activation of the
number so that they can update the call routing information at their
end.

 Which of our packages can a customer choose?
Customers can choose any of our packages (prepaid or postpaid) regardless of their existing package.

Hope it will help

Regards
