Where to find a comprehensive equation reference

[Nim]

Does anyone know where I can find a website or know of a book with a comprehensive list of equations? I want to know what they do, what units they use, etc... Some sort of reference you know?

 

[honestrosewater]

equations for what?

 

[dextercioby]

Tell me if you don't like this site
www.mathworld.com

It's got almost everything.

[mathwonk]

come on. what kind of question is that? a list of all the equations in the world?

thats like asking for a list of all the recipes in the world, or all the sentences in the world. or all the proverbs in the world, only far, farrrrrrr, more impossible.

think about your question a teeny bit more.

 

[Zurtex]

Would you like them all in lexical order with relivance to every different subject in the world?

 

[Nim]

It doesn't have to be all of them, just a lot. Doesn't matter what kind of equations either. I am mostly spending my time looking for ones that deal with physics. Sorry for not being clear enough.

 

[dextercioby]

Which branch of physics...?I doubt u'll find a book with such equations,just for your astoundment and admiration...

This site is a lot of help. I didn't find a category about equations, but I did a search and got a lot of results. At the moment I am trying to get a list of the basic science equations.

E=M*c²			Energy=DynamicMass*SpeedOfLight²		Joules=Kilograms*Meters Per Second
E=m/sqrt(1-v²/c²)*c²	Energy=Mass/sqrt(1-Velocity²*SoL²)*SoL²         ?
M=m/sqrt(1-v²/c²)*c²	DynamicM=Mass/sqrt(1-Velocity²*SoL²)*SoL²	?
KE=0.5*m*v²		Energy=0.5*mass*velocity²			Joules=0.5*Kilograms*Meters Per Second
KE=P*t			Energy=Power*Time		                Joules=Watts*Seconds
KE=V*I*t		Energy=Voltage*Current*Time		        Joules=Volts*Amps*Seconds
PE=M*C²			Energy=Mass*Speed of Light²		        Joules=Kilograms*Meters Per Second
PE=h*f			Energy=Planck's Constant*Frequency		Joules=?*Hertz
PE=m*g*h		Energy=mass*acceleration of gravity*height	?
P=E/t			Power=Energy/Time			        Watts=Joules*Seconds
P=V*I			Power=Voltage*Current			        Watts=Volts*Amps
P=I²*R			Power=Current²*Resistance			Watts=Amps²*Ohms
P=V²/R			Power=Voltage²/Resistance			Watts=Volts²/Ohms
I=P/V			Current=Power/Voltage			        Amps=Watts/Volts
I=V/R			Current=Voltage/Resistance			Amps=Volts/Ohms (Ohm's Law)
V=P/I			Voltage=Power/Current			        Volts=Watts/Amps
V=I*R			Voltage=Current*Resistance			Volts=Amps*Ohms
R=P/I²			Resistance=Power/Current²			Ohms=Watts/Amps²
R=V²/P			Resistance=Voltage²/Power			Ohms=Volts²/Watts
R=V/I			Resistance=Voltage/Current			Ohms=Volts/Amps
Q=I*t			Charge=Current*Time			        Coulombs=Amps*Seconds
D=S*T			DistanceTraveled=Speed*ElapsedTime		Kilometers=Kilometers Per Second*Seconds
S=D/T			Speed=DistanceTraveled/ElapsedTime		Kilometers Per Second=Kilometers/Seconds
T=D/S			ElapsedTime=DistanceTraveled/Speed		Seconds=Kilometers/Kilometers Per Second
c=n*l			WaveVelocity=Frequency*Wavelength		Meters Per Second=Hertz*Meters
l=c/n			Wavelength=WaveVelocity/Frequency		Meters=Meters Per Second/Hertz
n=c/l			Frequency=WaveVelocity/Wavelength		Hertz=Meters Per Second/Meters

look. if you want to understand physics, do not concern yourself with a huge pile of equations. learn the most important ideas. I have it on good authority, that these are the conservation laws.

more knowledgeable input anyone?

 

[dextercioby]

First of all i resent the idea of gathering a pile of equations from all areas of (in this case classical) physics which have nothing in common and whose relevance is totally lost.Basically u jump with ease from equations/equalities in SR to nonrelativistic mechanics and then to elecrticity.It's pointless.
As for units,they are totally mixed up.U can't have both meters & Kilometers,u can have only one species...
Plus the notation is totally unappropriate and would definitely generate confusion...

It's for a program that I am working on. If you type in an equation it looks at it and cuts it up in pieces and takes the parts that looks like a value needs to be added too and puts it next to a texbox. Once I have a lot of equations, I am going to add a search feature so its easier to find an equation for a certain task. I also want to add a description of each equation eventually.

There are many reasons why I think you'll struggle with that, but good luck, remember though equations without context are meaningless as anyone can write down a random equation.

In that case,i assume u won't be needing our help,we're not encyclopedias of equations...

Daniel.

 

[Nim]

we're not encyclopedias of equations...

Daniel.

Of course not, I was hoping that you might know of some books or websites that were though.

But since that doesn't seem to possible, and since I seem to be confused about some things like unappropriate notation and the use of measurements, maybe you can point me out to a site that can tell me how to do these things right?

 

[dextercioby]

www.wikipedia.com
is a good reference and
http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html
is another one.

Websites: Eric Weisstein's World of Physics (physic's mathworld)
http://users.pandora.be/educypedia/education/sciencephysicsfor.htm to several sites with formulas and such.
Book: The Cambridge Handbook of Physics Formulas (there are other similar books listed on this page.)

Perhaps you should include einsteins field equations (General Relativity)
