Apparent Conflicts with the Constitution

That lie detector. Sampling DNA. The truth drugs. Hollywood movie stuff, mostly. But all of this exists in the world, today. And people want to use them against criminals.

This may sound strange, but I'm talking of the rights of criminals. Does a person accused of an offence have the right to refuse any of these?

Turns out, he does. At least in India.

We often come across in the news happenings which seemingly violate the rights of a person accused of an offence. My take on the most common of these misconceptions.

Facing the Sky, Once Again

It did feel so great to get to do some more astrophotography, a couple of days ago.

I live in the city. So, as always, light pollution is an integral part of my astrophotography.

Read the entire story here:

Oh, and just in case anyone is interested in the technical details of this work (which, by the way, is an integral part of astrophotography), it's right there too.

Why does a simple gaze at our dogs give us such happiness? 

It's just the harmony of hormones, as the latest (Japanese) research says.
 
A dog’s gaze raises the oxytocin levels in its owner, prompting more social contact. In return, the owner’s gaze raises oxytocin levels in the pooch. This chemical loop unites the brains of two different species. “[It’s] a powerful mechanism through which dogs win our hearts—and we win theirs in return. ...

 “During dog evolution, we have probably selected for a behaviour in dogs that elicits a physiological response in us that promotes bonding,” says Larry Young from Emory University. “That behaviour is eye-gazing.”

Among wolves, eye contact is a threat, which is why they rarely look directly at each other. Young suspects that wolf pups might communicate with their mothers through looks, triggering the same kind of affectionate cycle that exists in humans. “This just goes away as they mature,” he speculates. Perhaps as wolves evolved into dogs, they simply kept this child-like means of communication, just as they also retained some of the physical traits of their younger selves. In this way, they could have tapped into the oxytocin loop that strengthens bonds between human mothers and their babies, and triggered an almost parental affection.

Indeed, brain-scanning experiments have shown that there are overlaps in the brain regions that become active when human mothers look at images of their children or their dogs. [emphasis added] “Diverse aspects of our biology appear to be tuned into dogs and children in remarkably similar ways,” write MacLean and Hare.
Wolves are wild, powerful, and fearsome predators, capable of bringing down even large prey. And yet, tens of thousands of years ago, some wolves started forming close associations with humans. The...

Out From the Bath

When you go for a shower, your spectacles should ideally accompany you. That is, if you use any at all.

Remember, it needs a bath too. Just like you.

IRNSS 1D successfully launched into space

IRNSS is the acronym for the Indian Regional Navigation Satellite System. To put it quaintly, it is India's own version of the USA's Global Positioning System, or Europe's GLONASS. 

IRNSS 1D, as the name suggests, is the fourth of the 7 satellites intended to be part of the complete satellite cluster. The first three of them, already operational in orbit, are geostationary, and the remaining four are geosynchronous. IRNSS 1D is the first of the latter. 

IRNSS would provide positioning and navigation services to Indian users, and thus, all its applications. Standard Positioning Service for all, and Restricted Service, an encrypted service available to "authorized users" (viz. military) only. Besides, it is also expected to maintain precise Indian Standard Time. 

PSLV C27 lifted off at 17:19 IST on March 28, 2015, from the Second Launch Pad of the Satish Dhawan Space Centre in Sriharikota, and successfully placed IRNSS 1D in orbit. The Polar Satellite Launch Vehicle is ISRO's workhorse launch vehicle, and has one of the best performance records in the aerospace industry. The PSLV-XL configuration, an augmented version of the PSLV modified to carry greater loads, was used for this launch.

Once this 1425 kg satellite was successfully injected into orbit as expected, its solar panels automatically deployed. The Master Control Facility in Hassan subsequently took control of the satellite. As of now, 3 of the 4 scheduled orbit correction manoeuvres have been successfully completed. Once all are complete, the satellite would be operational for service.  

As for the ground segment, a number of ground stations responsible for various functions have been established in various locations across the country. 

Since a GPS Network requires at least 4 satellites to be operational, with the successful placement of this satellite in orbit, IRNSS would be thrown open for beta testing.
In fact, registration can already be done here: http://irnss.isro.gov.in

If you're still confused about the difference between a geosynchronous and geostationary orbit, this guide is extremely helpful:

The harder you hit the ground, the more difficult it is to penetrate.

That seems to defy conventional wisdom, but it's precisely what has been found to occur.
 
Interesting isn't it?
When a meteor or a missile strikes the ground at a high velocity, it's easy to see the damage on the surface - usually in the form of a gigantic crater. But what exactly is going on following such a collossal amount of force? A new study led by...

A child of nine had something on her mind that she felt is worth being communicated to the President of her country.

"Why don’t women have coins or dollar bills with their faces on it?"

It did elicit a very special response.

Freedom of Speech and Expression: Beautifully summarised in a single paragraph

Justice Nariman, a Judge of the Supreme Court of India, on the freedom of speech and expression:-

"There are three concepts which are fundamental in understanding the reach of this most basic of human rights. The first is discussion, the second is advocacy, and the third is incitement.

Mere discussion or even advocacy of a particular cause howsoever unpopular is at the heart of Article 19(1)(a). It is only when such discussion or advocacy reaches the level of incitement that Article 19(2) kicks in."

Discussion is "the action or process of talking about something in order to reach a decision or to exchange ideas." At the same time, advocacy means "public support for or recommendation of a particular cause or policy." 

Whereas, "incitement" means "the action of provoking unlawful behaviour or urging someone to behave unlawfully."

The most basic of the Six Fundamental Freedoms guaranteed by the Indian Constitution beautifully summarised. 

Exercise your right to freedom of speech and expression responsibly. It means you are free to discuss, you're free to promote your cause. But you are not free to provoke people to behave against the law.

Dealing With Robots

Think robotics is out of reach? Think again. Presenting, the LEGO Mindstorms EV3, which you can afford if you can afford a Galaxy Tab. 

You can now build a robot just like you used to build models playing around with LEGO bricks as a child.

Here's my experience with this amazing gadget, and some little advice, if you don't mind:
http://astwavelength.wordpress.com/2015/03/24/dealing-with-robots/

It really is a wonderful robotics kit from LEGO. It suits the bill for everyone, be it the absolute beginner, or the professional designer looking to build a custom robot.

So, who's looking to join me? Can I count to have that person's word?

It may be a 4-star hotel, but one doesn't get the feeling of a 4-star hotel upon entering it. Leave alone from the outside, you don't get that feeling when inside either. The Eco Hub is much better than this. Maintenance is not fine. Although I haven't stayed here, the hotel doesn't seem very attractive from the outside as a 4-star hotel. A lot of improvement is required, and expected from The Pride Hotel, as a 4-star hotel in a future posh location such as Newtown (India).

It is a world-class destination for those who want to party or just take a swim, and do all that like to while away time. A monthly membership gives you access to all the facilities, which include a gym, swimming pool, badminton court, etc. It is very beautifully decorated. I would personally recommend anyone going there to visit the place at night, the decorative lights are wonderful.

The place is a good centre of knowledge. But it doesn't attract much people, rather appeal to the people. They should try to make the place more appealing to the people, so as to increase the footfall, and thus their revenue and the layman's knowledge about science. An average place in general.
