Yes I agree- But let's consider a linear extrapolation function based on statistics known in 2005, 1940 and 1750. Let's ignore abnormal population growth or population shrinkage due to war, famine, decease, weather etc.

Extreme_machinations- You are on the right track. Educate the Masses.

The Earth's current Human population is 6 Billion. Some time in 1940 the world population was 3 billion and around 1750 the population was about 500 million. Is there a scientific method to extrapolate the Human population for the date 5000 b.c? Thanks.

But wait...there's more... Try throwing a stone high up in the air...it will fall back. Now try even harder- after a while it will fallback. Seems like the speed with which you throw, does not let it to escape the Earth's gravity. Now, let's say that you have developed super human...

Darn it! So let me get this- A body with Mass warps space. This warp is the result of the ripple effect when the body first appeared in space at that particular location. A good example is- placing a boat in a pond. The boat displaces water and sends out ripples.

The Laser Interferometer Space Antenna is supposed to be launched in 2013. This will be used to measure Gravity waves that is still resonating from the Big Bang (Article from DISCOVER magazine- August 2005 edition).

So, the only way I can comprehend gravitational waves is by thinking that they are continuous (oscillation as explained by you all). So is it correct to think of it as continuous ripples across space? though the frequency and speed of this ripple is still unknown?

What gravity waves? Considering Gravity is the warping of space, then how is gravitational waves possible? Aren't we all sliding down the slopes of space due to the massive warping of space by ojects? isn't space pushing us down? Then why is gravitational waves a topic? Thanks.

Well that's now what I meant. I meant something like this. Simple: Fy | |\ |.\ |..\ |...\ |...\..T= 222N |...\ |...\ |...\ |...\ |___60_\____>Fx

How about Planks constant and black body radiation? Don't they mean heat from light that is proportional to the frequency? This light thing looks stranger and stranger the more and more I learn about it. I was thinking about the ramifications of photons being effected by heat if that was...

Seems like everyone student requesting help here fails to show a drawing of a free body diagram for all static/dynamic problems. Perhaps this should be made mandatory. A free body diagram is the first step to solving problems. This will also help them develop good problem solving skills.

So, I was baking this Indian delicacy I got at the local Indian grocery store commonly known as 'samosas'. I switched the light inside the oven to observe the progress and then suddenly this thought occurred to me. What happens to light when it gets heated up? What does photons do under...

Microwaves are bad for our bodies. They are so bad, they are being developed as weapons by the US military. It was a secret for a long time and soon to go into the field for the first time.

Several centuries ago, the radius of the Earth was found using the angles of the Sun rays formed on Earth. To find the mass you will probably have to use g=(G.m1.m2)/r^2. This means you will need the mass of another body, like the moon. Not sure how else you could find the Mass of the earth.

Always post a free body diagram first. This makes things easy for both yourself and the rest of us trying to help. Wall |\ |.\ |..\ |...\ |...\ |...\ |...\ |...\ |...\ |...60\ --------- From this diagram how can you conclude that the vertical component is her weight? The...
