A Meet with the champs!!

dear all,unlike my science article, this topic is my experience when i met the two badminton champions. I,being born in a family known for the perfect badminton,they played, that is my grandfather,father,uncle.... it is a opportunity for me to continue this tradition. I do play badminton but not like all of them. It was a opportunity for me to meet the world famous badminton players at a glance that is my grandfather and Nandu Natekar..Mr. Natekar was to honoured for his play at nagpur. He arrived at nagpur and then he attended the function organized by NDBA association. He leaved in some of his friend's house . But because of some incidence, AT night AT 12.00am he arrived at our house. we started prepation to clean the room. the next day while watching the sad demise of people at mumbai we had a conversation with him.. Being a famous personality,the simple thing about him is that he is simple,down to earth. . Not being proudy, he is a very simple man. today he left to pune and wished me a best of luck calling me a future nasa engineer. really it was a divine experience for me to meet him and my grandfather at once and conversating with them!!!!

Space Time Curvature!

Space time curvature suggests that the the space is curved with the time. nobody will understand it without any explanation. did u ever imagine why the sky appears to be in semicircle as u know that space is abounded. also the sun doesnt go straight east-west and not in a straight line with frame of refrence of the observer on earth.

imagine i am going in space in a rocket at certain altitude i let a beam of light travel in straight line but from observer on earth the beam appears to be travelling in a curved path. but as per einstein light travels in a straight line only and in any case curvature of light is impossible. this indicates that the space is curved and along with it the time that passes with the space.

It cant be called illusion as it is the reality in the fact of space-time curvature!! another example for this can be said as light from planets. This is Einstein's special relativity. this also implies that

the time is different for different observers. the time is curved.. This principle makes the sky semicircle and the concept of horizon and travelling of moon and sun actually photons from their reflecting surface to earth

TIME

the capacity of man to go to past was never thought unless and untill Einstein gave the principle that the speed of light is contant and is not affected by any thing in space. earlier newton gave the principle that when the sun will get destroyed immdiately then as there is no force of attraction which keeps the planets in orbits, planets will go away from the orbits. later einstein's discovery made it clear that 8min time is required for the light to come on earth from sun.. a simple concept is used to describe the effect of stop of time. time is the fourth dimension of space. now the atomic clock is used to calculate the actual time. the time that is on the earth and the SECOND which we calculate is different in space. as the altitude increases and we begin to move in the outer space, the second hand of the atomic clock ticks faster. a light clock works on the principle of reflection of a photon between two mirrors perpendicular to each other. the photon appears to bounce between the mirrors. now that is a standard second. but if we accelerate towards the velocity of light, the photon will travel in a slant line rather than perpendicular distance. so time period for the photon to touch the mirrors increases. if one light clock is in space and is accelerated to the speed of light then it will be travelling such a distance that with refrence to us we will find that that photon is not touching the mirror. and hence TIME STOPS. this is proved by experiments. the only thing is to achieve the velocity of light. the time willl stop for the OBSERVER ONLY!!! but for the person with that clock it is going. so 1 hour for that person may equivalate to about many days of earth and this is applicable when we recieve the near the velocity of light.!! there are mysteries which are termed with this TIME DILATION CONCEpt. One of my cousin asked me why is it not possible to go in past. but we can. the only thing velocity of light has to be achieved. coming out of this imagination we now move to another concept. the name is TIME CHANGES--
suppose that i am having a car. i am moving on the road with the speed of 100km/hr. a train with speed of 200km/hr was behind me. it then came infront of me at the moment when we are in uniform motion, and train crosses me, then i find that the train is moving with the speed as it was before when i observed the train when i was at rest. the same is for train driver. for both of us the speed with respect to each other is same but something is changing and that is TIME as the train is with same speed for car and car relative to it..
this concept makes time the 4th dimension of space... and it is curved space time.!!!

WE THE INDIANS, ON THE MOON!!!

Congratulations to all the indians. A proud movement for the indians arose at 20'31hrs when the first craft of india landed on the moon. Chandrayaan-1 which carried the MOON IMPACT PROBE dropped MIP in the moon's atmosphere. The moon impact probe, then fired its jets in opp.. direction to slow down the spacecraft from an altitude of 100km and fall on the moon. OUR FLAG IS ON MOON!!!! the mip has india's flag painted. we are the fourth country on the moon. A proud movement for all but a evolutinary movement in the dynamics of space research of india as i think. taking this as the leap of india's journey to the universe,i congratulate the isro scientist and my dear sir envolved with me in this journey. let us change wallpapers of our house those of with mip's pictures.
Wishing all the best to Isro for switching on the 9 instruments aboard the chandrayaan-1
HurraY!!!!!!!!

LAST DAY OF PHOENIX

Nov.2nd 2008, this is the last day when Nasa recieved signals from it's spacecraft on mars.. The phoenix spacecraft was launched on 4th august 2007. By travelling continuously for nine months,this spacecraft arrived in mars orbit.. The terror--- EDL or entry,descent and landing was performed exceptional by this spacecraft. On 25th may 2008, or 26th may 2008 for GMT+ citizens, phoenix succesfully landed on mars. The spacecraft started its work by digging the martian soil. later it started analyzing the weather and capturing images. the place where phoenix landed can be compared with the arctic region of earth. Designed to work for 3months, this spacecraft gave an extraordinary performance of 5months. Phoenix mission was acoomplished as it was basically targeted to find ice on the mars.later on after digging the soil,it discovered ice on mars. It took more than 25000 images of mars. it studied about the climate of mars. Dust storms were there near phoenix.. As, winters are approaching on mars, the sunlight is decreasing.. This spacecraft could have worked in this little sunlight but because of dust storms, it is unable. As there are no means of generating electricity from coal,water or other sources sunlight becomes the only source of charging batteries/generating electricity... All the instrumets aboard this spacecraft run on batteries that are charged from sunlight. But these batteries are not getting charged so phoenix ceased communications with earth.The temperature on mars in winters can be upto -87C. this is the lowest temperature recorded there. The q. that must be coming in mind must be that if there are winters on mars then after some time there will be summer and sufficient sunlight. so phoenix can again start working. But the max.temp recorded is about -5 C and usually it is -46C. in this temperature with no sufficient power, the instruments aboard the spacecraft which are directly exposed to martian atmosphere will get freezed and with no enough maximum temperature, this instruments can hardly function back!!!!!!!! SO we can call it as a Successful mission end. and can say phoenix has hibernated permenantly rather than calling its death. This Euphemism <> gives us idea that phoenix has done its job and is now resting.. "Phoenix not only met the tremendous challenge of landing safely, it accomplished scientific investigations on 149 of its 152 Martian days as a result of dedicated work by a talented team," said Phoenix Project Manager Barry Goldstein at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Phoenix findings also support the goal of learning the history of water on Mars. These findings include excavating soil above the ice table, revealing at least two distinct types of ice deposits; observing snow descending from clouds; providing a mission-long weather record, with data on temperature, pressure, humidity and wind; observations of haze, clouds, frost and whirlwinds; and coordinating with NASA's Mars Reconnaissance Orbiter to perform simultaneous ground and orbital observations of Martian weather.

Hole in the Wall!!!!!

Hey guys, i am not talking about Rahul Dravid- the wall of cricket team of india. i am talking about the hole which is there in the precious ozone layer. The ozone layer is a layer of useful gas called OzoneThe ozone layer resides in the stratosphere and surrounds the entire Earth. the sun is the only source of energy for us. the sun provides with energy. as the two sides of same coin, the sun also radiates harmful radiation. a part of that is the ultra-violate rays or UV rays. again the thought is suitable to this concept. there are three parts of UV_rays. UV-A,UV-B,UV-C. from these the UV-A and UV-C are useful in the formation of ozone. the prime function of ozone layer is to absorve this harmful ray. The hole which is made in the ozone layer above the south pole. Each spring in the stratosphere over Antarctica (Spring in the southern hemisphere is from September through November.), atmospheric ozone is rapidly destroyed by chemical processes.
As winter arrives, a vortex of winds develops around the pole and isolates the polar stratosphere. When temperatures drop below -78°C (-109°F), thin clouds form of ice, nitric acid, and sulphuric acid mixtures. Chemical reactions on the surfaces of ice crystals in the clouds release active forms of CFCs. Ozone depletion begins, and the ozone “hole” appears.
Over the course of two to three months, approximately 50% of the total column amount of ozone in the atmosphere disappears. At some levels, the losses approach 90%. This has come to be called the Antarctic ozone hole.
In spring, temperatures begin to rise, the ice evaporates, and the ozone layer starts to recover.

The ozone hole is defined geographically as the area wherein the total ozone amount is less than 220 Dobson Units. The ozone hole has steadily grown in size (up to 27 million sq. km.) and length of existence (from August through early December) over the past two decades.There is a possibility of depletion of ozone layer as it is reduced by cfc used in refrigerators,spray cans...!!!!!

Concept of orbit of satellite

on one night,looking at a dark sky,my friend wondered about a . he was worried whether it was an alien's craft. he called me and i told him that it was a satellite.. Then he knew about satellite but wondered how they are launched.The launching and orbiting of satellite is based on a very common principle of physics. The earth has a force of attraction. to escape from this gravity we have to exert a force that acts towards the center of earth. a common concept of weight=reaction force determines about our life. it is because of this that we are able to walk on the ground. if by exerting some force we are able to obtain more reactrion force than the weight then we can fly and if continuously we are exerting thrust then we are able to escape the gravity.popularly termed as the"escape velocity". For this if we want to reach an altitude of 340-370km we have to accquire a velocity of 7km/s. then once we are in orbit it is necessary to maintain the orbit. to keep the satellite near earth. for this there are gyroscopes. A gyroscope is a device which determines the axis of the orientation of the space craft. for eg. satellite ISS has 3axis== X Y Z.further it is used to determine the orbit and not to maintain the orbit.
let us consider one example. a person in a golf course has striked the ball and the ball is in the air for some time and than it comes down by showing a descend of some specific angle. this indicates that by application of force, an object can be raised. so if there can be any provision which enables us in a way such that the ball doesn't come to earth. even if it comes then again it is raised before touching. Thsi is the concept!!!!!!!!! For this there are motors aboard the spacecraft which fire after specific intervals of time. they use solar energy but mostly liquid/solid propellants. they have transmitters which transmit the data on the earth by use of solar energy. if it is a weather satellite then data is in form of 1s and 2s.
the various orbits are--
1] geostationary orbit
2] geosynchronus orbit
3] low earth orbit
4] polar orbit
5] middle earth orbit
6] geosynchronus transfer orbit
7] elliptical orbit
8] elliptical transfer orbitand many more..

Space-time reversal.....

WE COME ACROSS MANY DIFFICULTIES IN OUR LIFE. AT TIMES THE FATAL ACCIDENTS AS WELL. FOR A MOMENT WE THINK THAT WHAT WOULD HAVE HAPPENED WHEN WE WOULD HAVE BEEN ABLE TO CONTROL THE TIME
ALBERT EINSTEIN HAD DECLEARED THAT A TIME MACHINE CAN BE PREPARED IF WE ARE ABLE TO ACHIEVE THE VELOCITY OF LIGHT AND IF WE CAN ACCELERATE THE VELOCITY OF MOVING BODY TO 3,00,000 KM/SEC.
THE LARGE HYDRON COLLIDER EXP.. IS ABLE TO ACHIEVE THE VELOCITY OF LIGHT BUT ONLY 99.99999%
LET US THINK RELATED TO THIS.
IF WE ARE ABLE TO ACHIEVE {100%} THE VELOCITY OF LIGHT THEN WE CAN PREPARE A TIME MACHINE.
LET US SUPPOSE THAT I AM GOING IN THE HISTORY [1965], THEN IN A MOMENT, MY EXSISTENCE FROM THE WORLD WILL BE NO MORE AS I WILL REACH THE PAST.SO, AS SOON AS I ARRIVE, I WILL NOT BE SEEN IN THE PAST.BECAUSE I AM GUEST IN THE PAST { BEFORE MY BIRTH} I WILL REMAIN INVISIBLE AS I AM NOT BORN THERE. THERE, THE PEOPLE WILL BE LIKE THEY WERE IN 1965. LIFE WILL BE THE SAME AND IF I STUDY THE EVENTS THEN THEY WILL BE THE SAME.AT THE TIME OF MY BIRTH IN 1994, I WILL BE ABLE TO SEE MYSELF. BUT ME, AKSHAY DEORAS OF THE FUTURE WILL GROW LIKE I WOULD HAVE ON THE EARTH.
THIS ABOVE CONCEPT IS BASED ON THE CATASTROPHE THEORY WHICH SUGGESTS THE EXSISTENSE OF PARALLEL WORLD.
LET US SUPPOSE THAT IT IS 1ST JANUARY 2012
THE TIME IS 12:12:12, A BIG ASTEROID TRAVELLING IN THE OPPOSITE DIRECTION OF THE REVOLUTION OF THE EARTH HITS THE EARTH AND EARTH SPINS BACK TO 1990
for eg. EARTH IS A BALL AND SOMEBODY HAS HITTEN THE EARTH WITH A CRICKET BAT.
BECAUSE OF IMPACT OF NATURE AND FORCES OF NATURE, WE ALL WILL TRAVEL BACK. THE AGE OF ALL OF US WILL REDUCE AND WE WILL GROW SMALLER AT ONCE, THEN AFTER THAT EVENT, WE WILL AGAIN START GROWING AS PER THE RULE OF NATURE. THE EVENTS AND ACTIVITIES THAT WILL TAKE PLACE IN EVERYBODY'S LIFE WILL BE THE SAME AS IT HAD HAPPENED IN THE EARLIER EARTH. FOR EG. ON 12TH SEPTEMBER 2008, I HAVE READ A ARTICLE ABOUT UNIVERSE, NATURALLY WHEN IT WILL BE 12TH SEPTEMBER 2008 IN THE NEW WORLD AND THE TIME WILL MATCH, I WILL AUTOMATICALY READ THE PAPER AND WILL GET THE KNOWLEDGE. THE EVENT OF READING THE NEWS PAPER WILL NOT HAPPEN BEFORE THE TIME. IT WILL HAPPEN IN EVERYBODY'S LIFE. BUT AS OUR BODY GROWS SMALLER WE WILL BEGIN TO LOSE THE MEMORY AND WE WILL NOT BE KNOWING ABOUT THE EVENTS SO IT WILL BE OF NO USE.
BUT THIS DOESN'T IMPLY THAT ALL THE ACTIVITIES WILL BE REPEATED
ANYTHING CAN HAPPEN IN NATURE.IF A CHILD IS BORN IN THE PAST i.e HIS FUTURE IS NOT INCLUDED IN THE PERIOD FROM HIS BIRTH TO THE ANTI-SPINNING OF THE EARTH, THEN BY COMING IN A PERSON'S INFLUENCE, HE CAN CHANGE THE FUTURE OF A PERSON BY BRINGING ABOUT A DISTURBANCE IN HIS NATURAL ACTIVITIES.
IF A PERSON WAS OUGHT TO MEET AN ACCIDENT ON ANY DAY AT SOME TIME LET US SUPPOSE THAT THAT TIME IS 10:10:10, SO IF THAT PERSON SETS OUT FROM HIS HOUSE AT 10:10:05 THEN HE IS SAVED IF THERE IS NO ACCIDENT WRITTEN IN HIS DESTINY. BUT IF THERE IS,THEN EVEN IF HE SETS OUT EARLY THEN THAT PERSON WILL MAKE DELAY AND THE PERSON WHO WANTED TO SET OUT AT 10:10:05 WILL GO OUT AT 10:10:10.HE WILL MEET AN ACCIDENT. ALL THE ACTIVITIES IN THE LIFE OF A PERSON WILL OCCUR AT THE RIGHT TIME AND HE WILL NOT BE KNOWING ABOUT IT.BUT WHEN THE EARTH WILL AGAIN REACH AT THE TIME FROM WHICH IT HAD GONE FOR ANTI-SPINNING THEN AT THE MOMENT THAT IS- IF THE EARTH HAD ANTI SPINNED AT 09:09:08 THEN WHEN IT WILL BE 09:09:09 ALL THE ACTIVITIES WILL BE NEW FOR THE PEOPLE AS THEY WERE ABOUT TO HAPPEN BUT THE EARTH WENT UNDER A MYSTERIOUS SPINNING. IN OUR SURROUNDINGS, THERE MAY BE A PERSON WHO MAY BE AFFECTING OUR LIFE. EVEN A SECOND IN THE INFLUENCE OF THAT PERSON MAY CHANGE OUR LIVES AS ON ADDING SECONDS, A MINUTE IS FORMED AND ADDING MIN.. A HOUR IS FORMED.
FROM THIS WE MAY IMPLY THAT ALL THE ACTIVITIES THAT ARE TAKING PLACE IN OUR LIFE ARE PRECEEDENTED ALREADY IN THE PARREL WORLD. WE MAY MAKE A TIME MACHINE BUT IF I AM IN THE MACHINE WHEN THE EARTH ANTI-REVOLVES THEN I WILL NOT BE ABLE TO GO IN THE PAST PERIOD BEFORE MY BIRTH EVEN A SECOND BEFORE MY BIRTH AS THAT WORLD WILL BE THE WORLD FROM WHICH I HAVE DEPARTED AND WILL ARRIVE IN THE SAME WORLD
THUS IT WAS A GIST ABOUT MY THINKING RELATED TO THE SPACETIME REVERSAL AND THE CONCEPT TIME MACHINE AND THE IMPACT. IT IS CURRENTLY IMPOSSIBLE FOR US TO GO IN THE PAST.

A revolutionary change in America!!!

Guys, today's result of the race to the white house was a historical moment. Defeating John McCain, Barack Hussain Obama won this extra-ordinary race. This 47yrs old man who is full of revolutionary ideas, became a role model for the black people. he is a perfect example of victory of obtaining the rites to the black people.He shall thus be treated as Mr.Lincon of 20th century. Though being an Indian, i am a human. Staying kilometers away from the Grant park,chicago i was able to feel the victory of black people. This day thus shall be never forgotten by Barack Obama who has overcomed many difficulties in his life. Being born in Hawaii Obama as a child was not lucky enough to stay in comfort with his parents as his parents got seperated 3yrs after the marriage.Unlucky Father could see his child only once and that was the last time as he died in accident in 1982. After that his mother came to Indonesia. But Barack's mother sent him to his maternal grandparents in USA. he stayed with his grandparents for many years and did his schooling also. His mother turned back to Hawaii. Obama as an adult also consumed marijuna cocaine. He,himself comitted this describing as his "Greatest Moral failure"
Obama then studied political science.Initially he worked as director of the Developing Communities Project (DCP), a church-based community organization originally comprising eight Catholic parishes in Greater Roseland (Roseland, West Pullman, and Riverdale) on Chicago's far South Side.During this time he met his keneyan relatives. He entered into politics in 1996. His mother died in 1995. He got married to Michelle Obama in 1992. He has two daughters Malia Ann and Natasha.'Dreams from my father'[1995] was a novel written by him. his race was full of ups and downs but now being elected as the 44th President of USA.
"YES,WE CAN" THE SLOGAN WHICH IS FOR HIS CAMPAIGN APTLY SUITS HIS PERSONALITY....
getting on the chair of president of america on January 20,2009 this person is born to bring a evolution on earth.HATS OFF TO HIM

India's mission to Moon

Chandrayaan-1 which had blasted off from Shriharikota on Oct 22nd is now at the last part of it's journey.... with the apogee of 3,84,000km from earth the advance craft has now entered the lunar orbit.. a series of firing of LAM took Chandrayaan-1 to this success. Chandrayaan-1 maneavour started at 4"51pm IST and it continued till 817 seconds... This placed Chandrayaan-1 in the highly elleptical orbit which is of 7500km x 504km. But on 12th nov, after a series of firings,chandrayaan-1 reached its planned orbit of 100 x 100km which includes aposeline off 100km and periselene of 100 km. The next major event is to drop the MOON IMPACT PROBE on the surface of moon,which carries India's flag. It will be dropped in few days. The challenges are not yet over. The eleven instruments aboard the spacecraft should now perform well. After many days, they will be tested as they were continuously exposed to the earth,outer,lunar space. Chandrayaan-1 is india's first mission to moon. It is a contribution with ESA,NASA.
