I'm talking about big, world-view changing science. All the big principles are there. Evolution. Lawfulness of nature, etc.

As I see it, there are three kinds of Science left:
a) Applied science - putting the principles to work in new technology. Like understanding of biology --> medicine or physics --> engine development.
b) Detailed science - working out details of well established theoretical frameworks, like finding the nth new particle in high energy physics...
c) Pseudoscience - working on stuff that is pratically untestable, such as string theory where no one seriously believes we will ever achieve energy levels to test theoretical predictions.

If not, what is left to be done?

1).u can write a^(n)-b^(n)=c^(2)-d^(2)
here a,b,c&d are natural & real numbers.n is a natural number.
like 7^(3)-4^(3)=48^(2)-45^(2)
2).u can also write for any number say x having any power say
n can also be written as
x^(n)=y^(2)-z^(2)
here x ,y & z are natural & real numbers
like 3^(3)=14^(2)-13^(2)
from this show that it is impossible to write
a^(n)-b^(n)=x^(n) for n>=2.

As we know that gas (Exhaust gas) is much compressible than the liquid (Petrol and diesel), with so much combustion engines in our world that use petrol and diesel, this huge physical volume (Petrol and diesel) lost every days in our space, will it cause any effect to the atmospheric pressure, or cause other effects to our environment?

For years I've wondered about this. Some say it is a Urban Legend and others say based on strong medical facts that it is real? The majority of test cases that I've read say it's real? What are you thoughts?

At the moment of death the body looses 21 grams of body mass. It is said this is the soul leaving the body. It is believed by many that the soul weighs 21 grams. Out of 2000 participants in a international medical study done in 1993, 98.7% of persons at death lost exactly 21 grams of body mass, minus or plus .010 tenths of a gram.

You always hear of the concept of counting sheep jumping over a fence in order to help put yourself to sleep, but... as a city-person with little exposure to sheep, I'm wondering if real sheep evidence anything even remotely resembling this capability... or of even having a bouncy gait (a la many cartoons). Peripheral question I guess would be, anyone know where in the world that concept came from, particularly if sheep don't have a spring in their step to begin with?

If my car gets 25 miles per gallon. And gas is $3.00 per gallon. And I travel 3 miles, how much have I spent?

Can you write out the equation/formula. This isn't homework, I'm just not good with math and want to know.

Thanks
