Isn't it unlikely that they are more knowledgeable than the smartest scientists?

it is uncertain..maybe they took the secret formula from the scientists only..
because believing that those people are more knowledgeable than the smartest scientists is little difficult from me..

the logic you have  given me is accurate but..
in order to know there secret we have to do research on it and
pile up a lots of information about it...
and point to be notice...if they tell you that how did they did it they will just be in loss...so
in order to get the answer you yourself have to find it..

I don't remember my password given to me...
that is why whenever I have to login I have to enter my gmail first to get the password....
that is irritating that's why I hardly sign out..

Of course, the enemy ships usually get by me and destroy the planet I am guarding but it is the thought that counts.

are you in army or a kind of a security guard?

Physics is a great trouble for me..and I am stuck in one question...
Please anyone help...

The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved my the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also..

study..the more you study....the more you gain knowledge...
but as I see....I waste a lot of my time...in chat with my friends..

#98 Re: Science HQ » Half Life » 2013-07-17 01:17:45

maybe...but I don't like any type of games...
cause I feel it is a wastage of time..

The half-life of a radioactive substance is the amount of time that it takes to love half its radioactivity..:)
I only know that much about it..
