Universe... and the mind

At times I sit all alone in my balcony during the wee hours at night gazing at the sky, looking at the Big Dipper , which is called the Saptha Rishi mandal in Sanskrit, and gazing at billions of stars remembering my child hood poem on the twinkling stars and forgetting the time.

There always remains an intriguing question which science and philosophy find it very difficult to answer. "What is reality?"

 Is what we as humans 'see' be proclaimed as reality? Are the billions or trillions of stars whose light infact has left them millions of years ago be perceived as reality?

If there was no evolution, would the planets or even matter would have ever existed - as what we see are the by products of our well developed conscious minds?

Science states that such questions are invalid. The so called consciousness is not a valid concept as per science. 

And then comes the concept of time.  Wikipedia defines time as follows:

Time is a measure in which events can be ordered from the past through the present into the future, and also the measure of durations of events and the intervals between them.^{[1][2][3][4][5][6][7]} Time is often referred to as the fourth dimension, along with the three spatial dimensions.^[8]

As per the definition there are three key elements: past present and future. But what exactly is "past", "present" and future and more specifically "present"

Water On Mars

Google has doodled the latest finding by NASA: existence of water on the Red Planet. The Doodle itself is one of the most creative works, depicting the Red Man sipping water with a straw :-)

 As per Wikipedia:-

Water on Mars exists today almost exclusively as ice, though it also exists in small quantities as vapour in the atmosphere^[1] and occasionally as low volume liquid brines in shallow Martian soils.^[2] The only place where water ice is visible at the surface is at the north polar ice cap.^[3] Abundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole and in the shallow subsurface at more temperate latitudes.^[4][5][6][7] More than five million cubic kilometers of ice have been identified at or near the surface of modern Mars, enough to cover the whole planet to a depth of 35 meters.^[8] Even more ice is likely to be locked away in the deep subsurface.^[9]

Space always has fascinated humanity and the quest for extra terrestrial has always been ongoing.With growing technology, space missions have reached to higher levels in investigations and have been able to peek into the vastness of the universe giving more insights and changing the way the Universe was understood once upon a time. Very soon the evidence of extra terrestrial life will be inevitable and might provide the real reason of the existence of life,

Liked a song, after a long time! This is a new single from One Direction.

Teacher's Day

Google celebrates Teacher's Day by doodling in their home page. The doodle has rightly depicted teacher's insights and the knowledge that is imparted that shapes the future of an individual.

 A big salute to all the hard working teachers of the world.. !

" Appearing instead of '@'

This started since few days, whenever I type @ symbol in my laptop keyboard, " was appearing and I was trying to figure out why this was happening. As a workaround I used to copy the @ symbol from the net to type my email address!

Finally I figured out that this is due to the keyboard setting. The default setting was UK.

--> windows key+ shift and select English(United States). This has resolved the problem.

PL SQL Gems

I will start posting some interesting snippets for PL SQL similar to UNIX GEMS that can be used as a quick reference.
 

Google's New Logo

The world's favourite search engine Google has new logo from today. The same has been doodled on its home page as well.
