my mother dont know calculus and algebra yet she is good in practical mathematics .i say that it is not necessary(i maybe wrong) to learn calculus .that is if we are good in addition, multiplication.... that will do(dont mistake me i am good in maths and algebra)

according to newton gravity is an attractive force.in that case earth should be attracted towards sun isn't?
This maybe silly but a small doubt

Quarks
can they be splitted???
i maybe the first scientist to split a quark

may be in aeroplanes or in rockets
i thought that it was a good idea anyway thank you for your suggesstion

And yeah... Electrons are always in orbit around the nucleus just like a fan around its center...So there's never any empty space
you are wrong there when you throw a particle towards the fan it moves through the fan even if it rotates(sometimes missess-the particle should be very faster than the velocity of the rotation of the fan )try this in your home
thats the case with the atom also
when the alpha particles cross the electrons faster than the velocity of the electron it moves away from it due to the inertia.
thats why rutherford uses fast moving alpha particles

The answer is, they'll hit the ground at the same time. Gravity accelerates all objects at 9.8m/s2, regardless of their density or weight.
isn,t it in vaccum. it happens only if there is vaccum.in the normal state the object which is heavier strikes the ground first
i believe i am correct for i am not a genius like you

is it possible to use nuclear fuels in cars ..i didn't mean uranium and plutonium and other things.i thought we could use some elements which when splitted produce a small amount of energy. say for example chlorine when it is splitted it produces 0.954mev of energy.
can this be used in cars to produce electricity
and run them in electricity

we can use water to produce electricity constantly.if the quantity of water dont change we can use the same amount of water repeatedly to produce electricity.
If the above statement is true we can use this above technic in bikes.(ie)use water to produce electricity when it does not get exhausted....
though i have a doubt ... producing electricity with water is large scale
in that case it cannot be used in the bikes
but is there any alternative can hydro electric project be used on small scale
as small as a petrol tank in bike or a litter bigger

to baby astronaut
even if you measure the height of mount olympus mons from the seafloor it is still the highest mountain.for referrence see google
But if they find a still higher mountain they will declare that mountain as the highest(i used this line for your title)

They might have used artificial insulin(stem cell culture technic)
they would have cultured beta cells to produce insulin artificially

I cant really understand your ques can you give me a better explanation

Maybe it is elliptical like our earth for it may also rotate something(just an imagination)

when we use water to produce electricity(hydro-electricity)do water get exhausted. that is the quantity of water will change or not

this maybe a little silly...but i have here a debate...
Is algebra and calculus necessary for a comman man to live in the society???
That is, are they used in the pratical life??
I vote that they are not necessary for a common man..
What about you...

Hi, All
I feel its my moral responsibility to correct all misconceptions
regarding HIV /AIDS.
I can do this because I am educated enough to comment on this. This
message is from Mayank who is working in Ranbaxy. He is serving as
Brand Manager (Product Manager) handling anti HIV/AIDS portfolio
(called as
Antiretroviral Drugs) in Ranbaxy.
Please read following points carefully & don't send emails related to
Medical ailments without having complete knowledge about it (even
partial knowledge could be grossly dangerous).
* HIV (virus) requires *ONLY* *Blood or Semen* as medium to transmit
from one body to another.
* HIV *can not* transmit even through *Saliva*(mucous) i.e . even if
HIV-infected patient coughs or smooches and another person is exposed
to his sputum (cough) or saliva, the virus still can not transmit
because concentration of virus particles in sputum is almost NIL &
exposure to air anyway kills virus in fraction of seconds.
* In case an HIV-infected person gets an injury (like the cut in below
mentioned story) and he is bleeding, the virus can transmit to another
person only if another person has a cut/wound in his body & that too
when blood from both person comes in contact with each other* (this is
also very very rare unless bleeding is very high) and not otherwise.
* HIV can *never survive in any other liquid * medium also other than
blood or semen (& please for God sake ... never in Pani Puri wala
pani)
* Even if one drinks an HIV infected blood (or semen) of someone
(ingest through Gastro Intestinal track), the virus can not survive in
the acidic pH of stomach*. Highest extent of acidity is 0 (practically
not
possible) so imagine 1 as pH which is in our stomach. (This pH can
burn your own finger in less than a second if you dip in that acid).
* Exposure of less than 1 second in AIR KILLS the HIV virus*( hence
story of needle pricks in Cinema heatres is a crap). Even if blood
from a wound (of infected person) dries up (*blood clot*), *the virus
dies*and can not infect anyone else.
* HIV transmission is *ONLY* an *INFECTION* i.e.entrance of virus in
one's body. It *DOES NOT MEAN AIDS*.
* An HIV-infected person (after entrance of virus) can progress to a
condition of AIDS only after *8 to 10 YEARS *(not in 15 days as in the
Pani Puri story)
* It is *not HIV (virus) that kills a human* .....the virus attacks
immune cells (cells that fight against foreign pathogens/antigens) and
hence a person's ability to fight against infections & diseases slowly
diminishes and person ultimately dies of a disease which could be as
simple as TB.
* Most importantly, HIV is no longer a dreadful disease ... it is
"*CHRONIC MANAGEABLE DISEASE*" just like Diabetes or Hypertension.
* If there is anything you need to be careful from to prevent HIV is
*Blood transfusion* (check before taking) /Blood donation
(use sterilized needles only) and any *blood contact during an accident
*or so where amount of bleeding is very high.
Thank you for reading this message.. forward this message to everyone..to your friends

Where Does Space End? It Must End Somewhere!
in Astronomy and Cosmology
Posted
There is no chance for human to find the end(size) of the universe. But man can find the end(lifetime) of the universe. any way according to big bang theory universe will expand to its maximum space by swallowing the empty spaces. then there will be no spacefor the universe to occupy so it will crunch again .This theory is also called as the Big crunch theory
