The Andes Mountains, South America | International Space Station
Scott: "Good morning, Earth and The Andes Mountains!" 
"Happy Sunday to you!"

The Andes is the longest continental mountain range in the world. It is a continual range of highlands along the western coast of South America. This range is about 7,000 km (4,300 mi) long, about 200 km (120 mi) to 700 km (430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. (Source: Wikipedia)

What shape is the universe? The reason I ask is because very few shapes make sense with our current understanding and if we are wrong then what shape could it be

the problem with that spherical theory is it would suggest a world with no beginning nor end due to infinite space meaning infinite matter so many theories of the universes death would be dis-proven (though that is why they are called theories)

1] Sin( ) is a measure of how much perpendicular two objects/forces are.
2] Log(effect) = cause,....10^cause = effect.
3] Transpose of a Matrix = Rotation by 180 degrees.
4] i = rotation by 90 degrees,....i^2 = rotation by 180 degrees, i^3 =rotation by 270 degrees.
5] e^(i.any angle) = rotation anticlockwise by that angle.: e^(-i.any angle) =rotation clockwise by that angle.
6] Cos( ) is a measure of how much aligned two forces are.
7] Diagonal of a matrix is its axis of rotation.

NEW BLOG POST: Do You Actually Learn about Real Life from Art? |LifestyleScience.eu

Many works of art are undoubtedly a valuable inheritance for humanity and an actual representation of the potential of the human brain, among others. However, is art (or can ever be) adequate enough to explain the real world?

[1] How Sin( ) is a measure of how perpendicular two objects/ forces are.

[2] How cos is at measure of how parallel two forces/ objects are.

[3] i = Rotation by 90 degrees. i^2=Rotation by 180 degrees.
i^3 = Rotation by 270 degrees.
i^4= Rotation by 360 degrees.

[4] Transpose of a Matrix = Rotation by 180 degree.

Transpose of (Transpose of) a matrix = Rotation by 360 degrees.

[5] e^i(angle) = rotation by that angle.

[6] sin(30) = 1/2 because at 30 deg the influence of a force/object reduces to half.

For example the shadow of a stick reduces to 1/2 at 30 deg.

[7] A x B = |A| |B|sin(angle btwn A & B).

total combined impact in cross product depends upon.. . . . .
how strong A is
how strong B is.
How perpendicular A and B are w.r.t each other.

e.g A ball hitting a wall will produce max impact at 90 deg.

What would have happened when the universe originated? Is it possible that you years ago, another universe would have existed? Probably before the big bang? if it did what if it did what happened to it is it possible that our universe the same fate?

+Nitin R The common theory was that there was a singularity, antimatter and matter began to interact, which caused a rapid expansion, which created the universe. The Big Crunch is when the expansion of the universe reverses. The reason why is if the universe's expansion rate does not exceed terminal velocity, then the gravitation of the universe will pull itself into a blackhole singularity, or a singularity similar to that of the proposed Big Bang model. The universe could go past the escape velocity of its own gravity and freeze to death as well. We're not sure.

A bowling ball and feather fall in world’s biggest vacuum chamber

NASA’s Space Power Facility in Sandusky, Ohio, is the biggest vacuum chamber in the world, measuring 30.5 meters by 37.2 meters, and has a volume of 22,653 cubic meters.  If you watched Commander David Scott drop a hammer and a feather on the televised Apollo 15 mission, then you probably already know how this one ends, but that doesn’t make watching it play out any less spectacular.

It was Galileo who first discovered that in a vacuum, if you were to drop two objects from the same height, they’d hit the ground at exactly the same time, regardless of their respective mass. In the atmosphere of Earth, we rarely – if ever – get to see this phenomenon. That’s where this big vacuum chamber comes in

British physicist Brian Cox wanted to see this  phenomenon play out in a vacuum, where there is zero air resistance to affect the acceleration of Earth’s gravity. This was filming done for the BBC 2 show, Human Universe,

Hello friends,

This week my post refers to how spirituality and new age movements are most of the time a different side of the same coin that has to do with religiousness.

NEW BLOG POST: The New Religion of the 21st Century (part 1) | LifestyleScience.eu 

Read Here: http://ow.ly/L2HKg
So today that the old school religions are losing customers not all of the lost ones describe themselves as atheists, right? Apart from the ones that don't bother with worldview issues, there has appeared a new very effective trend. This trend has made a combination of buddhist religions and quantum mechanics. The buddhist religions offer…

Earth has a hidden layer unknown till date. 

What we have learned that is Earth has three main layers deep. But the mankind’s knowledge on what’s underneath our feet is less. Much less that there is a saying, that scientists know much more about the sky than the floor. Our present knowledge of the layers of the Earth has been derived by using seismological and magnetic field data as well as other theoretical calculations, it’s possible to get a sense of the actual size and composition of our planet’s nether regions. Since its too difficult to go down there, scientists have been using techniques similar to Medical imaging.

But, is this verified? The phenomena is not observed and is just theoretically proclaimed.

Thanks for an e-friendship on @EmpireAve+ Hello from Lettland : www.pavilosta.lv/en + BEST REGARDS with the Goat's year 2015 begining ! 
How different ar e flowers in a meadow and raindrops in a window, so different are regions in Latvia. On the west coast of Baltic sea, as a amber blob shimmer Pāvilosta region. With the salty sea water smell and freshly smoked flounder, in the colour of rural oven baked rye bred.

NEW BLOG POST: The 4 Mindset Steps to Take Positive Action and Enhance Your Life (part 2) | LifestyleScience.eu

After describing in the 1st part how I recognised that in my whole life there was a huge lack of initiatives and actual creative procedures, I, as well, found that I was never trained to set plans and goals. Shouldn’t we have goals?

I know it sounds obvious, everyone supposingly wants some things for their lives. But…
