Oh Rayleigh?!

Oh Rayleigh?!

So the sky is blue because short wavelengths of light coming from the Sun (blue, etc.) are scattered more than long ones (yellow, red, etc.), reflecting the short wavelength light into our eyes instead of it passing through the atmosphere as part of white light. Sunsets are red for the opposite reason … but yeah, why isn’t it violet?

Violet has an even shorter wavelength than blue light. So does indigo, whatever that is. There’s a good logical case for a purple sky, right?

Want to know the answer? Why the sky isn’t violet?

Do ya? 

The truth is that the sky is both violet and blue. But the color receptors in our eyes don’t see violet very well, so we get the (incorrect) impression that the sky is just blue. Some birds actually see well into the violet and ultraviolet, so the sky must look trippy as hell to them.

.Beginnings

This newfangled micro-blog is either (1) a chance to test my creative web  skills, (2) a space where I can throw my deepest thinking (sort of like my philosophy) of my deepest soul, (3) a cool to place to express what I see through the lens of my camera (did you know that iPhone is the most popular camera in the world?!), or (4) some mixture of everything.

If you continue to read this, I can assure you three (3) things: (1) impeccable grammar and spelling (thanks to auto spell check), (2) a total lack of entertainment (literally, everyone’s view of entertainment is different), (3) an alliteration of photos, and (4) so many listings.

(and of course parentheses)

The historic moment is finally here.

It's Official: Voyager 1 Has Left the Solar System

The Historic Moment Is Finally Here.

   After months debate, scientists around the world now agree that NASA's Voyager 1 has become the first man-made object to leave our solar system (iknowsomeofyoumaywonderwhythismatters). And it only!! took 36 years to make the 12 billion mile-long journey.

Voyager is now on its way to another star. At it's current speed of 100,000 miles per hour, it'll only take her 40,000 years.

Sound I like (also known as music)

Before you start to read this post, listen to this music as you read through.

image

My taste in music is “eclectic”*. I like all of the music I listen to, so obviously I have really good taste in music.

There is nothing quite so magical or moving as an powerful orchestral piece played by a full symphony orchestra. I have nothing against poppy music, nor do I have anything against wild bashing and screaming music (except that I mostly hate it), but if I were stuck in Antarctic for the rest of my life, I would die quickly of Hypothermia listen to epic soundtracks like:

“Imagine the Fire”, Hans Zimmer, The Dark Knight Rises

“The Promise”, Michael Nyman

“Extraction Point” , Hans Zimmer, Modern Warfare 2 (a video game with epic score?)

“Escape”, Craig Armstrong

 London Philharmonic’s finest.

 Or simply instrumental.

If you’re still listening to the music, I hope so, right? Imagine you’re sitting in that room, as a group of 50 people playing a song – using violins, bass drums, cellos, and a touch of piano – it precisely melds together into a beautiful, powerful, multifaceted sound…  and it’s just magical as the conductor keeps the whole thing together..  

As you might have seen in movies (like Harry Potter), a wand is portrayed as an instrument for magical occurrence. If you realize, a conductor’s baton (wand) also produces magical waves. I mean, with the flick of a wrist, a conductor can shape music like a painter with his paint brush. He can create striking thunders from the bass drums to the electrifying sharp pitch of the violins.

*I really do have a weird (wide spectrum) taste in music.

By the time I finished writing this, I realized that music is an expression, as it can only be played or heard (its really hard to ‘talk’ about music).

lone explorer from Earth around Saturnian system

Lone Explorer From Earth Around Saturnian System

An awe-inspiring journey captured by Cassini in the 13 years it’s been observing the Saturnian system. It is humbling and breathtaking to see the spacecraft taking images of the glowing and sun-eclipsing Saturn.

Preemptively, in few hours, Cassini will burn up and disintegrate like a meteor as it enters the Satrun’s atmosphere at 70,000 miles per hour.

It is truly a privilege to be part of NASA’s JPL to explore the grandeur of the universe.

svishnuu - THE WAY I SEE IT
THE WAY I SEE IT

In a nutshell or two: I love aerospace. I'm an engineer, writer, a photographer, and a reader. And, of course, a blogger. I spent my high school years in New York City, managing to defy every urban bum new yorker stereotype (except for the "bum" part). My school life basically revolved around Aviation and Science Bowl. If you continue to read this, I can assure you three (3) things: (1) impeccable grammar (yea, ok) and spelling (thanks to auto spell check), (2) a total lack of entertainment (literally, everyone’s view of entertainment is different), (3) an alliteration of photos, and (4) so many listings. (and of course parentheses)
