Theories of the Brane

String Theory is the dominant approach right now, and it has some success already, but the question is whether it will develop to the stage where we can actually solve problems that can be tested observationally.If we can’t bridge the gap between this ten dimensional theory and anything that we can observe, it will grind to halt.

In most versions of string theory, the extra dimensions above the normal three are all wrapped up very tightly, so that each point in our ordinary space is like a tightly wrapped origami in six dimensions. We see just three dimensions, the rest are invisible to us because they are wrapped up very tightly.

If you look at a needle, it looks like a one dimensional object from a long distance, but really it’s three dimensional.

Likewise, the extra dimensions could be seen if you looked at things very closely. Space on a very tiny scale is grainy and complicated–its smoothness is an illusion of the large scale.

That’s the conventional view in this string theories.

An idea which has become popular in the last two or three years is that not all extra dimensions are wrapped up–that there might be at least one extra dimension that exists on a large scale. Raman Sundrun and I (Lisa Randal) have developed this idea in our work on branes.

According to this theory, there could be other universes, perhaps separated from us by just a microscopic distance; however that distance is measured in some fourth spacial dimension, of which we are not aware.  Because we are imprisoned in our three dimension, we can’t directly detect these other universes.

Ethical axioms

Ethical axioms are found and tested

not very differently from the axioms of science.

Truth is what stands the test of experience.”

–Albert Einstein

Learn from yesterday

Learn from yesterday, live for today, hope for tomorrow.
The important thing is not to stop questioning.”

— Albert Einstein

Einstein about problems

“Do not worry about your problems with mathematics, I assure you mine are far greater.”

(Letter to Barbara Lee Wilson, 7 January 1943)

Three Rules of Work

“Three Rules of Work:

Out of clutter find simplicity;

From discord find harmony;

In the middle of difficulty lies opportunity.”

Albert-Einstein-007

Einstein on paradigms

“We can’t solve problems by using thesame kind

of thinking we used when we created them.”

–Albert Einstein

I found this citation in a course related to sustainability and innovation.

This quote has a lot to do with the paragidm shift ideas mentioned here, here and here.

And this is the basic understanding to comprehend the theory of exponential returns that lead to singularity.

We are living amidst a revolution.

Albert Einstein Quotes

“Two things are infinite: the universe and human stupidity; and I’m not sure about the universe.”

“If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut.”

“Not everything that counts can be counted, and not everything that can be counted counts.”

Einstein on Moral Value

“Try not to become a man of success but a man of value.”

–Albert Einstein
