Every sense i had my son, who is 18 months old now. I have had upper discomfort in my chest around my ribs and really it kinda feels like maybe in my lungs. I though at first that i might of pulled a muscle somewhere in there so i went to the doctor and they told me nothing was wrong with me... Well it didn't go away so i went to one hospital which they said the same thing, so i have literally went to every hospital within a 45 min drive, all together i have had blood drawn which they said they tested for blood clots, i've had 3 ekg's and they said my heart was fine, i have had x rays on my lungs and they said there was nothing wrong with them either and eventually said that it was anxiety so they put me on medication for that well the discomfort has never went away so i stoped taking the med's and now i think that there just over looking something because i'm young... I'm only 21... What does anyone think is wrong with me?

I am refering to Bohr's theroem of hydrogen. He used a formula involving the "Rydberg constant". My question is why are energy levels assigned negative values is it because the negative sign says that the energy is giving off to the surroundings? or is it because the negative sign signifying that the energy of the electron in the atom is lower than the energy of a free electron? Thanks for helping

I've heard there are two ways of solving quadratic equations. One way is to use the quadratic formula and the other way is to factor. I've been leaning toward factoring because I thought it would be easier, but I'm still having trouble. Can someone tell me a good way to factor? Or should I just forget factoring and study the quadratic formula?

This is NOT meant to be a discourse on ethics. … I am NOT saying that such a thing should ever be tried. I am merely curious if it is theoretically possible. … In other words, can the eventual human evolution into an altogether new specie, based on its built-in beneficial gene mutations, be somehow "genetically accelerated" to render the same end result as that of the painfully slow natural selection process?
