Global Warming, and its chilling.

Posted on June 13, 2007. Filed under: global warming, science, social |

I would like to put two things straight,

  1. Hail Sameer, who is just like a spark plug which never forget to ignite.
  2. I drive on comments, more comments I get, more easy it would be for me to write.

Now coming to the topic of global warming, though I was not invited to G8 or G5 summit and am not seeing and upcoming chances to be there with those decision makers. One thing is quite clear, they are not going to make great deal of change. Yesterday there was an article in Times of India, which stated that America have money to invest in every xyz research but not in the fields related to Global Warming and modeling. And things aren’t going to be simple any time soon. There are many reasons, and most of them are related to economics and politics. I am no Guru in either of them but understands one simple thing that is PROFIT, and Global Warming is going to bring more and more profit.

Political Sense

America is in no mood to cut its emission, and probably it can not, for few very simple reasons, that there is huge political pressure on White House from industrial lobby, which is very strong in US. I haven’t been to US, but one simple thing from which I have this inference, is the number of years for which American Industry is standing. For India it is not more than 60 to 70 years, and for them there industrial history dates back to nearly 200 years or so. And in 200 years and for a nation which plays a very dominant part in international politics, any sort of industry will have its windows in political system.
And as America is in no mood to cut down in emission norms and Mr Bush’s feeling that the onus to cut emission of green house gases are on India and China. I am not hoping from something great from EU. And as the Big Daddies are not going to hold their barrels down, the aspiring Big Daddies (G5), are going to follow the suite. This means that we are not going to see and major bill passed in US senate, and this in turns also negates a possibility of a bill being passes in Lok Sabha, or even proposed for that matter. While the meant time we will continue feeding on American Media which will keep on reporting about Paris Hilton and about Brangellina and sometimes (rarest of rare) about few outdated models of global warming.
By the way I really did not likes Paris Hilton’s sobbing photo. And Oh yes, she was not crying for the sentence she got, but for the terrible failure of the recently held G8 summit which was focused on GLOBAL WARMING.

Economical Sense

Now come to the economics of every thing related to global warming. Economics is the wheel on which runs politics. You name me a thing and I will tell you that it is in some way or other adding to the global warming. And this just do not limits to the non living things but to the living beings too. I was thinking of adding another topic, like Scientific sense but wont be able to do that as I am already under sever time crunch, my exams are running, so I have to run. One of the major reason behind global warming is undoubtedly the burning of carbon fuel, and this world is running on fuel economy. Whether it be OPEC, US, China or India all are eying hydrocarbon fuel some where or other on globe. This all is required to maintain the fuel security so currently I am not foreseeing any kind of halt in this spree. Then comes the other major source, which would be much better considering global warming, that is radioactive fuel. And for our country many more developing countries like us, there are already many stringent conditions to follow before getting some kind of certificate from a group of developed nation.
Every industry produces some kind of pollution, and this pollution in some way or other contributes to the production of green house gases. As our economy is growing our requirements will only see an increment. One of the important decisions which we have to take is before making any sort of choices, because some products require some really nasty process to be manufactured.
I will try to bring spotlight on scientific sense behind global warming and the extent to which we can manage it through our daily life.

Set minds to motion!

Posted on January 26, 2007. Filed under: science |

from:flintspark.blogspot.com
hi all!

I was thinking to pose some good questions that occured to me and that might be materialized in the future.

1.Lets build a bamboo microsope.

In the pursuit of taking science to villages,we try to make a bamboo low cost mircoscope.

The only costly thing in it will be the lenses.

The microscope tube as well as the mechanism all will be made up of bamboo,since it is locally available,rough and tough,prevents entry of external light.

The problem is to design the mircoscope’s mechanism.

Firstly,it must be able to move the main tube up and down,

next,it must be able to move the lens up and down.Simply put,both coarse and fine adjustments.
also how to attach the lenses with the rim of the bamboo tube.

How will you do it?

2.This is the original idea(i think) of Mr PS Ghose,of National Bal Bhawan.

Why to go on buying a laptop,when you can build it?

I mean,since desktops are now available at about 15000,so why not assemble our desktop on to a small atteche case?(say vip case)

The heating would be one big problem and the bag must be able to close on completion of work.

We shall need to drill out holes of the sides to provide the connection.
It shouldn’t have its own power suppy,thats ok.
but it must have its own monitor.and keyboard and mouse and possibly speakers.

then we shall need to provide it with adequate protection from elements.The hard disk needs to be cushioned.

think on it.and gimme an ingenious solution.be descriptive and then lets matertialize.

3.This one is quite funny and is all bout lateral thinking.

What can you hold only with oyu right hand?
Don’t answer if oyu already know.

Answers to those who comment.

hugs for a great repulic day,
sameer

Theories of plant translocation

Posted on January 11, 2007. Filed under: science |

Another post form flintspark.blogspot.com

 

Being a student of life sciences also,it is inevitable fo me to include some talk and theories of life sciences.

Firstly,

What i need is a physical application in form of a product of device which uses this phenomenon.

It has been shown by Henry Dixon,that the accent of sap and water to the leaves from the roots is only due to 3 reasons:

1.The transpirational pull
As water evaporates from the leaves of the plant,there is a suction created by this action resulting in a pull drom the roots.
You can also see this by taking a porus pot and gluing a tube filled of water to it,the tube dipped in a jar of water.As the water evaporates,the water level in the tube rises.

This is how water rises to trees even over 100m in height.

2.Cohesion and Adhesion.
The water molecules are cohesed(attracted) to each other forming a continuous column of water.they also are adhesed(attracted) to the xylem vessel(a thin tube) in the plant.

Since xylem vessels are thin,they help in conduction of water in small plants by cappliarity(passive asscent of liquid in a thin tube).

3.Root pressure

The water molecules surounding the root are very much eager to enter the root(due to less water potential in the root).
Thus the root exerts a pressure towards the water in the xylem vessel.

To check this out,cut a potted plant above the root at any place.Sap will exude out of it.

My question is:Is there an device required or already made that works on these principles?

I propose,a motor less water escaltion system to fill up your overhead water tanks.But it doesn’t seem plausible.

You can ask it if you don’t understand any point.

But if you have understood,start thinking.

Hugs for a great brainstorm,
sameer

Misson on moon.

Posted on December 6, 2006. Filed under: India, science |

I wrote a post before about the proposed manned mission on moon from India and a score of other nations. Then I told that there are few better options, rather than going for a manned mission on moon, and India should place a larger picture for the global audience. After all such things are just to show your international poweress.
NASA is now trying to make a permanent station on either of the poles of moon. It could have been ISRO’s idea, if I would have been working with them. Yes it will take much more money than sending a man or two to the moon. But hey sending such rockets is not a monthly business, rather in many cases its a life time opportunity. So, tax more and make a thing which we can call The First. Moreover, to me, its a far better idea to set up a permanent station on moon, though not human, but robotic(NASA are going for manned station and I am not ready to pay that much tax).
It would certainly be working there for much more time than a human can work. And if some one tells me that India is not that good in robotics then I would like to remind them that Indian is possible to do any thing in a time span which is unimaginable by many others. We can easily develop robotics, more over this is era of multinational activities.

And a follow-up by my friend here.
