Hi again. I thought I had it figured out but I am confused again When I multiply it by y^2 I get [math] 6y+8=-y^2 [/math] then i set the right hand side to 0 to get [math] y^2+6y+8=0 [/math] this is general quadratic form isn't it? So I plug the coefficients into the quadratic formula and get -2, -4 What are these numbers? If I put them into the original quadratic form i get -7,-3.5 I don't get it Thanks again

Thanks Callipygous Great help

[math] /frac{5}{y} [/math]

Hi, I have never really been a math type of person and am taking a intro to math course at uni. I am asked to solve an equation in the same format as the one below and indicate clearly the method used. The trouble is I have no idea how to do it [math] {6}/{y} + {8}/{y^2} = -1 [/math] I would really appreciated any help. Thanks edit: I don't know how to make fractions with latex

Thanks for the replies guys I guess I will take that intro to chem course at uni now Cheers

Hi, I am learning about molecualr biology and it seems as though it deals with certain molecules. Is it just chemistry with a different name and purpose or is there more to it? Thanks

Hi, I a have used just about every Java IDE there is. I suppose it is totally a personal choice on what you like. My favourite is IntelliJ. Its small, fast, doesn't intrude on your code or modify anything with its designer.

Thanks Kix

Hi, I am new to everything medicine and was hoping someone could tell me the field in which scientists actively research causes and cures of diseases ect Do you have to go to med school or do you study medical science at uni if you were interested in being a researcher? Where does the money go to when raised in say a fight cancer charity? Any info would be greatly appreciated. Thanks

Ok, I'll have one more crack at it before i sleep One of the definitions was "Is the material substance of the universe that has mass, occupies space, and is convertible to energy. " If someone could give me an example of matter turning into energy that could explain energy to me. But i will take a guess. A lump of wood is matter, you set it on fire. The fire turns the wood into heat and heat is a form of energy. Is that right? If so, can you turn heat back into some kind of matter is is it doomed to stay energy forever?

Hi again, I've been doing a bit of googling and think i am getting closer to understanding. I search for define: matter and the first definition was substance: that which has mass and occupies space; "an atom is the smallest indivisible unit of matter" This is what confuses me. It says an atom is the smallest unit of matter but on other sites it says electron, protons and neutrons are clasified as matter and they are smaller than atoms. Also, when you go smaller and get to quarks and neutrinos ect they are matter. And if you kept going and say for arguments sake strings were the smallest things, 1 string would be matter right? So is a string made of energy or is energy just a label for force? Sorry, i'm confusing myself even more

Thanks yourdadonapogos, That kind of cleared my misconception up a bit. But I am still a little confused. If matter and energy are different forms of the same thing and matter can be in various forms, then what is energy? Thanks again

Hi, I am quite new to science and have been wondering what the difference between energy and matter is. Is matter just a bunch of atoms? And energy is a force? Are atoms made of energy and if so how can it be called matter when there is only energy? Sorry if these are dumb questions Thanks

Hi, I made a post in a couple of buddhist forums and had some quite interesting answers. I would like to hear if scientists can explain it, or if it is even an issue in neuroscience. This was the post: Here is a link to the post in a buddhist forum to see some buddhist answers http://www.lioncity.net/buddhism/index.php?showtopic=10996 Is this sound known in nueroscience? Thanks for any info
