Welcome to the all-new Parallel Spirals

I deleted all the previous posts since they’re basically not the best of my writing. I will remain offline till 2nd December, 2006. But, you will see on the timestamp that the date is: 25-11-2006. This is thanks to WordPress.com’s timestamp edit feature.

I plan to limit myself seriously in this all-new blog. This is an attempt to make blogging a more productive experience. Feedback and comments are always welcome.

Early Life and Star Formation?

The Danish National Space Centre [DNSC] did a study that proves the connection between early life on Earth and star formation in our Milky Way.

For the simple minded, scientists used some technique to see the relation between the amount of cosmic material coming from space from a period of intense supernovae explosions and star formation coincided with a period of intense growth and decline of bacteria. They then realised: This can’t be a coincidence. Cosmic material increases, bacteria growth-decline cycle increases. There has to be a connection. Atleast, that’s what I understood.

Centauri Dreams explains it more scientifically.

Dark Energy

I first posted this on my space blog at http://blog.seds.org/pradeep. I recovered the post using the Wayback Machine here.

NASA had a big press release on dark energy. If you’re new to the concept of dark energy or have only heard about it and don’t know what it exactly is (like me), go to this wikipedia article for starters.  For those of you guys who understand high-tech space language, go here. Er, you guys can read the comments too.

Phil Plait over at Bad Astronomy assures us that the language in the press release is more people-friendly.

Stories Worth Following

The CS Monitor‘s report on India stepping up ties with Africa, in the face of China doing the same. Don’t understand why they do this. The national interests of India and China can’t be the same. If Africa benefits, good for them. If India benefits, good for us. But, if India is going in just to compete with China, it’s bad strategy.
 
MS to reconsider it’s China Policy from BBC News.

Rice traders and environmentalists have warned the Government of India against experimenting further with genetically modified crops .No news report in CNN-IBN. Have to check their website though…

GoodNewsIndia has several good articles related to agriculture practises and re-invigorating ancient water pools – at a time when it is being said that wars will be fought over water.

Last but not the least…India’s mission to the moon…oh! did I say India’s manned mission to the moon?

Glad to be here…

I probably won’t be blogging for the next couple of days…have to make some arrangements vis-a-vis my studies…exams getting closer…winds getting colder…brrr…and no @#$%^& announcemnt from MU….hmmph…

Hindustan Times has introduced a practise of providing the email ids of people writing the stories – the reporters – this is a wonderful concept and I hope other newspapers follow the example…

A nuclear-less world

Note: I wrote this on my earlier blog hosted as http://parallelspirals.blogspot.com/. I recovered the text from the WayBack Machine. This post appeared on Ocober 16, 2006 as per the timestamp. I’m trying to collect here again all my old writings spread on various blogs.

The whole world takes all its nuclear explosives and gets rid of them. A thorough search of the Earth is carried out with satellites to make sure that no evidence of nuclear energy is left on Earth. All Uranium, useless to Earth and useful only to nuclear energy is also packed and taken far away into space and explodes. The world is then rid of nuclear energy.

What a lovely scenario to contemplate. But, not so possible in the next 10-20 years. Nuclear alternatives, it seems are necessary for the coal dependant economic powerhouses of India and China. Until you have effective and useful alternatives to coal and as cheap,nuclear power would be very hard to get rid of.

But, if it is eventually got rid of, won’t all the good stuff – like nuclear medicene, go along with it too? Who knows what other hidden purposes Uranium can be used for?

Think about it.

If there is a perfectly scientific explanation to this, kindly send me a link in the comments section. I’m too lazy to search on the Internet or do research on what I think? If you want to make this a PhD thesis, go ahead.

Is the Earth a PMM?

Note: I wrote this on my earlier blog hosted as http://parallelspirals.blogspot.com/. I recovered the text from the WayBack Machine. This post appeared on Ocober 16, 2006 as per the timestamp. I’m trying to collect here again all my old writings spread on various blogs.

A PMM is a machine which can output work for no input of energy. That’s sort of like your car running without petrol.

Is the Earth a PMM?
Is the Earth rotating without any input of energy? If it gets an input of energy, where does it get that from? I understand that the Earth revolves due to the effect of gravity as a force causing the Earth to move around it. But how does the Earth rotate?

If the Earth is a PMM, it violates the laws of thermodynamics. If the Earth can violate the laws of thermodynamics, why can’t we? Rules are meant to be broken, right?
