« on: 17/01/2011 10:19:55 »

   What kind of ceramic displays physio-electric effect? using this ceramic, and  sound waves can i evaporate water ,

  Does household ceramics, display physio-electric effect?

Physics, Astronomy & Cosmology / Superstring theory?

« on: 03/02/2010 04:13:46 »

 Is Superstring theory is useful for study universe?  Because it can only assume but this theory practically does not apply...
        But i am really confused ... I think we need more discovery in mathematics.

  If this theory completes what's going to happen?
  Can we invent time machine?

Famous Scientists, Doctors and Inventors / Theory of everything ( Einstein dream)

                            EINSTEIN
                        [ Invalid Attachment ]
 I really wonder when i heard the meaning of theory of relativity, it's very carziest theory ever proposed..
  Enistein spend 30 years on theory of relativity, but he couldn't explain. and it was unsuccessful..

   If he had explained this theory ....it was to have been the ultimate achievement of 2,000 years of investigation into the nature of space and matter,
  This is his third try..
 
            His first theory of Special Relativity (1905) gave us E = mc², which led to the atomic bomb and unlocked the secret of the stars.....
         
            His second great theory was General Relativity (1915), which gave us space warps, the Big Bang, and black holes......
                   
            But many don't realize that his greatest theory was never finished: "a theory of everything". Einstein's crowning achievement was to have been the unified field theory, an attempt to "read the mind of God"


 Wonder theory ...

He is great,

            PHENO-RHG-DRUG

   This is first experimental research on chemistry,

Aim:- Confidential

 
   I have an impressed mathematical solution, when i was doing mathematics... I got an idea to make a pure solution , which can manage to cure all deadly virus,
 I am in progress,,, I need some great author books where i can study about
anatomy
 I have studied more... Now some thing is missing in my result... I don't know what? But soon i will exlain what is this....

      work in progress......

I am trying my level best

                                                                                      ·     Traffic signs, traffic signals and rules of the road regulations made under section 118 of Motor Vehicles Act.

·        Duties of driver when his vehicle is involved in an accident resulting in death or bodily injury of a person or damage to property of a third party.

·        Precautions to be taken while passing un-manned railway crossing and

·        The Documents he should carry with him while driving a vehicle.


so, is there any web-site where i can learn.. The above topics.. [O8)] [O8)] [O8)]

Famous Scientists, Doctors and Inventors / Molecule that replicates has been created:

« on: 26/03/2009 11:24:51 »

A new molecule that performs the essential function of life - self-replication - could shed light on the origin of all living things.

If that wasn't enough, the laboratory-born ribonucleic acid (RNA) strand evolves in a test tube to double itself ever more swiftly.

"Obviously what we're trying to do is make a biology," says Gerald Joyce, a biochemist at the Scripps Research Institute in La Jolla, California. He hopes to imbue his team's molecule with all the fundamental properties of life: self-replication, evolution, and function.

Joyce and colleague Tracey Lincoln made their chemical out of RNA because most researchers think early life stored information in this sister molecule to DNA. And unlike the stuff of our genomes, RNA molecules can catalyse chemical reactions.

"We're trying to jump in at the last signpost we have back there in the early history of life,"

But i too was thinking how? []

Molecule Bew

Rather than start with RNA enzymes - ribozymes - present in other organisms, Joyce's team created its own molecule from scratch, called R3C. It performed a single function: stitching two shorter RNA molecules together to create a clone of itself.

Further lab tinkering made this molecule better at copying itself, but this is not the same as bringing it to life. It self-replicated to a point, but eventually clogged up in shapes that could no longer sew RNA pieces together. "It was a real dog," Joyce says.

To improve R3C, Lincoln redesigned the molecule to forge a sister RNA that could itself join two other pieces of RNA into a functioning ribozyme. That way, each molecule makes a copy of its sister, a process called cross replication. The population of two doubles and doubles until there are no more starting bits of RNA left

Technology / How to make radio waves to work??

« on: 25/03/2009 09:28:18 »

 How can we control radio waves ..  and make the object move.. is it possible and why not micro - waves
 Bcz .. we can transfer energy. can covert to mechanical in microwaves we can do like that? and by passing AC microwaves to the diodes contaning Dc accepter...
        By connecting the circuit to some of the application..

 will the heat is produced....  we can control it..

My question is ?
 How can we control radio waves ..  and make the object move.. is it possible and why not micro - waves

New Theories / Atoms and there power !!!

« on: 20/03/2009 07:00:20 »

   When i was reading organic chemistry i got an idea!

        The imagined that atoms as a no of orbitals.....     
 see when an losses the electron Energy is released.. When the enerhy is released the orbit breaks.. when these happes the orbit again re-arange itself and search for an electron, due to the increase in nuclear charge. The orbit start expanding and then break and settle as the cloud.....

    Consider the atom lossess all it's electrons and then it will be unstable and also such type of atom is not found...     


  can we use such type of atoms for organic....


  I just imagined please don't scould me... If i said any wrong please....

Chemistry / To molecules or atoms have colour?

« on: 18/03/2009 07:11:21 »

 
1) do molecules/atoms have color !! if not why visible light shows color of different wavelength, and frequency.

2) consider our universe was not black !!! what was the possibilites? would there be a atoms,

3) Do you agree that our universe is black so it has atoms ? what force exists behind?
