Can magnet affect human speech?

SCIENCE EXHIBITION

1] EFFECT OF MAGNET ON SOUND DIRECTLY
WE KNOW MAGNET IS VERY USEFUL IN MANY THINGS
WE USE IN OUR DAILY LIFE AND NOW AS SCIENCE IS DEVELOPED WE ARE USING FOR OUR PROTECTION OF LIFE IN MANY ASPECTS..
BUT NOBODY MUST HAVE THOUGHT OF EFFECT OF MAGNET ON SOUND. IF ANYONE LISTENS IT, HE WILL SAY IT IS RUBBISH. SOME WISE PEOPLE MAY SAY YES WITHOUT READING THE TITLE AND CAN SAY SPEAKERS?. BUT I HAVE USED THE WORD DIRECTLY. THIS MEANS WHEN WE TAKE A MAGNET NEAR THE OBJET FOR EG.. TV WHERE THE SOUND THOUGH IS PREVIOUSLY CONVERTED, BUT THE SOUND COMES OUT. IF WE TAKE A POWERFUL MAGNET CAN THAT OF THE RADIO NEAR THE TV,ITS SOUND CHANGES. IT GOES DEEP!!
EXPLAINATION--
EVERY MAGNET HAS A MAGNETIC FIELD. THIS ARE THE IMAGINARY LINES,USUALLY CIRCULAR AROUND THE POLES AND FROM THE POLES TO THE BOUNDARY MAGNETIC FIELD IS ACTIVE. IF WE KEEP A PARTICLE IT GETS ATTRACTED TOWARDS IT. BUT OUTSIDE IT IT DOESNT. LIKEWISE UNLIKE THE LIGHT SOUND IS A DISTURBANCE THAT TRAVELS IN FORM OF WAVES.
IT IS SIMILAR TO RIPPLES IN WATER..
NOW LET US SUPPOSE THE RADIO AND TV ARE PERPENDICULAR TO EACH OTHER. THE WORK DONE BY THE FORCE OF THIS TWO OBJECTS IS PERPENDICULAR.. WE KNOW THAT COS 90 IS O. SO NOTHING WILL HAPPEN.
LIKEWISE IF WE SEE IN THE ABOVE FIGURE,THAT IF WE KEEP RADIO JUST NEAR THE
WHEN THE MAGNETIC LINES INTERSECT EACH OTHER <>
THEY MAKE A SEPERATE WAVE WHOSE ENERGY IS LESS THAN THE FORMER TWO
SO THOSE WAVES COME IN OUR EARS AND WE FEEL THE CHANGE
THIS IS APPLICABLE TO ALL OBJECTS WHO HAVE A WAVE NATURE
{ IN ABOVE REFRENCE, THE MAGNETIC FIELD THOUGH IS NOT A WAVE BUT WE CONSIDER IT AS WAVE BECAUSE OF ITS FIELD}
{ IT IS A LIMITED BOUNDARY [AMPLITUDE] BUT SOUND WAVES HAS A MORE BOUNDARY[LIMIT] AS COMPARED TO THE MAGNETS[ RADIO ONE]}

My condolence to OCO Team!!!



dear all,


another sad news comes up after the satellitte collison of iridium 33 and cosmos 2251. i was thouroughly following the orbiting carbon observatory mission of Nasa since many days. Everything was going smoothly. i was in school in computer lab watching nasa tv. i didnt have lunch also as i was busy throughout the recess watching the launch. as there were no speakers we were unable to hear the countdown. we all became worried because of the 4mins delay and after that launch took place at obout 3:25:30 pm IST. as the recess was over i had to rush down to class. when i saw the news about the failure in seperation of the satellite and taurus rocket, i was shocked


HERE ARE SOME CHARACTERISTICS OF TAURUS ROCKET-


Taurus is a four stage, solid fuel launch vehicle built by Orbital Sciences Corporation. It is based on the air-launched Pegasus rocket from the same manufacturer. The Taurus rocket is able to carry a payload of around 1,350 kg into a low Earth orbit. First launched in 1994, it has successfully completed six out of a total of eight military and commercial missions.[1] Two launches have ended in failure, including the February 24, 2009 launch of the Orbiting Carbon Observatory mission.[2]

ITS MISSIONS--

Spinning galaxies can form a shortcut to universe?



dear all,
i have come up with one more idea. yest.. i was drinking milk and stirring the milk. as all know we see a hole that directly goes to the bottom of cup passing through the milk but not touching it. i.e not getting wet. similar is the eye of tornado. the tornada is nothing but air spinning in circular manner i.e clockwise in s.hemisphere and anti in northern hemisphere. the eye is the most dangerous place where the pressure and wind speed is maximum because of its configuration. but if we throw any object from helipcopter in the eye of tornado then that directly will fall down on the ground. such tornadoes is not possible in space<>.
so we can say that when a liquid,gaseous,solid object gains circular velocity then it produces a pit. this can be the answer to the wormholes or the space shortcuts.
we know the process of fussion of any cellestial objects. they are attracted by the gravity then they move circular to each other then they move away. this process continues till they collapse on each other. galaxies are enormous. if in future such thing is ought to happen because of configuration of universe. so a passage may form which can take us to some new place. regarding the passage,we can say we can go for time travel.

NEED OF SPACE TRAFFIC CONTROLLER IN SPACE?



Dear all,


its a sad news for all the people who have interest in satellites. two of our friends namely iridium 33 and cosmos 2251 have collided in space.


In an unprecedented space collision, a commercial Iridium communications satellite (IRIDIUM 33, NORAD ID 24946) and a defunct Russian satellite (COSMOS 2251, NORAD ID 22675) ran into each other on February 10, 2009 above Northern Siberia, creating a cloud of debris. The impact occured at 16:56:00 UTC (11:56:00 AM EST), at Latitude 72° 30' 04'', Longitude 97° 52' 46'', Altitude 788.68 km (490.0 miles). into 600 pieces it can be said that it was not a malfunctioning.Iridium Satellite LLC operates a constellation of some 66 satellites, along with orbital spares, to support satellite telephone operations around the world. The spacecraft, which weigh about 1,485 pounds when fully fueled, are in orbits tilted 86.4 degrees to the equator at an altitude of about 485 miles. Ninety-five Iridium satellites were launched between 1997 and 2002 and several have failed over the years.
Yesterday, Iridium Satellite LLC lost an operational satellite, the company said in a statement. According to information shared with the company by various U.S. government organizations that monitor satellites and other space objects (such as debris), it appears that the satellite loss is the result of a collision with a non-operational Russian satellite.
Although this event has minimal impact on Iridium's service, the company is taking immediate action to address the loss. The Iridium constellation is healthy, and this event is not the result of a failure on the part of Iridium or its technology. While this is an extremely unusual, very low-probability event, the Iridium constellation is uniquely designed to withstand such an event, and the company is taking the necessary steps to replace the lost satellite with one of its in-orbit spare satellites.
Johnson said the collision was unprecedented.
Nothing to this extent (has happened before), he said. e've had three other accidental collisions between what we call catalog objects, but they were all much smaller than this and always a moderate sized objects and a very small object. And these are two relatively big objects. So this is a first, unfortunately.
As for the threat posed by the debris, Johnson said NASA carried out an immediate analysis to determine whether the space station faced any increased risk. The station, carrying three crew members, circles the globe at an altitude of about 220 miles in an orbit tilted 51.6 degrees to the equator.


from this as there are air traffice controllers here on earth,there have to be space traffic controller. There are two issues: the immediate threat and a longer-term threat,.It turns out, when you have a collision like this the debris is thrown very energetically both to higher orbits and to lower orbits. So there are actually debris from this event which we believe are going through the space station's altitude already. Most of it is not, most of it is still clustered up where the event took place. But a small number are going through station's altitude.


Most, if not all, of the debris is expected to eventually burn up in Earth's atmosphere

The journey to the Boundary of Universe!!!



Written by-


Akshay Deoras,Resp.. Thombre sir


Dear all,


this is my first article including the mixed ideas of me and my sir. although all the articles have been written after a prolonged discussion with him.


'THE JOURNEY TO THE BOUNDARY OF UNIVERSE'


This universe is great. the mysteries are locked in it but no one knows where are the keys.


we keep on saying that the universe is infinite and it has no end. but i believe it is the opposite. the universe is expanding continuously,every hour,minute second,microseconds. so it is not very easy to locate the boundary of universe as it is very clear that the boundary also moves forward with the growing universe. but there is a relativity in this aspect. if we suppose that there is a object A from where the boundary is 1 km away then bz of constant and uniform expansion the boundary will always remain at a distance of 1km from A. so the problem that comes is how to locate the boundary. if we take a spacecraft and try to go out of universe IN ANY DIRECTION, as the distance is enormous it will take millions of years to reach.. but if we follow the velocity of light the time will be less. the emphasis on this article is to tell abt the possibility of boundary,the abv one was a introduction to the concept..


article A]


- Resp.Thombre Sir


now if we want to reach the boundary of universe,we will definately have to accquire velocity more than that of light. so there are such radiations known as Hawking's radiation. this means as per einstein,the time for the observer<> will stop and we will go to the past. so we will not go towards the end/boundary of universe but towards the begining of universe.. this will change everything


P.S THE TIME TO REACH THE BOUNDARY WILL TAKE US IN FUTURE AS PER MY OTHER ARTICLES. SO THE ABOVE BOLD LINE IS USED


article b]


- Akshay Deoras


a continued part


similarly we can go in future and if it is so, then we will overcome the rate of expansion and we will go ahead the boundary of universe. thus again by relativity, we will move parallel with the boundary and the distance will be same.


How to identify that there is a boundary


possible explaination-


i, believe that it will be a region where the all energy <> will sum uo together and because of it if we try to escape the boundary suddenly we will be pulled in<like a trampolin> the more u jump the more u go up. The question arises that will the be powerful enough to bring back the light from escaping.if seen it is possible as well as not possible. as said by stephen hawking,Bekenstein-Hawking radiation escape through the corner of black hole.it is the gravitational force which is a major component in this deflection of light
so it is possible as the gravity that strong of the black hole changes the path of lightso all these forces may bring back the light.Think about it!!. if it is possible then we can locate the boundary of universe even by not going there. we can study the impact on objects which are near to the boundary like we do to study black holes.

so by observation from earth itself we can locate


3] by Resp Thombre sir-


this energy may be a energy less area. so nothing can pass through it. we have a controversy on it. but let us see what happens. nasa claims boundary abv 100 miles from earth.


the question arises what is behind that boundary. if we cross it will we be lost in time? i think if we cross that limit, we will go back to the begining of universe. possible explaination will be given by me soon. but may be to the shortcuts in universe and catestrough theory!!!


who knows what happens...

dimensions


we know the uses of dimensions.certainly as they are there,we are there. if we would have lived in 1 dimension space then we would have moved in one direction and we would have become flat


2] if we would have lived in 2D space then we would have gone back and forward but not up and down


3] as we have live in more than 2D including 3D we can move up and down.


4th dimension and 5th dimension are geometrically different and astronomically different
in space 4th dimension is of time.i want to state that why cant waves be the 5th dimension of space. note- i mean the em waves. we cant go with the sound as sound needs a medium of transmission in space--- solid/liquid/gas. but EM waves transmit without the need of medium
we say space is 3d with time 4th d. but every body in space has tendency of transmitting em waves either the paticles of alpha,beta,gamma
the dimensions can be called as the sides of object. now according to this defination, EM waves though are'nt the real sides of object but we can say they come out from the edges. likewise time goes with space so, it is a part of space like wise the EM waves are a part of cellestial objects..
