With a vote scheduled to decide the fate of Pluto set for August 24th, do you think we should accept the new definition that any round object orbitting the sun is a planet, or not. If not, then Pluto would be cut loose from our current solar system and we would only have 8 instead of 9. If you think we should accept the new definition, then we would go from 9 to 12. This includes a new planet that would find a spot in between Mars and Jupitor, one of Pluto's moons, and another called "Xena" beyond Pluto.

What are your thoughts, would you accept it?

In your professional opinion, do you believe that fire is what caused the collapse of the World Trade Center buildings? Especially WTC #7?
Just a question, please don't crucify me.

Thanx to someone answering my earlier question i know how to do expand. At least i think. Is this long assed answer correct? (a+b)^14=a^14+14a^13b+101a^12b^2+414a^11b^3+1101a^10b^4+2103a^9b^5+3053a^8b^6+3452a^7b^7+3053a^6b^8+2103a^5b^9+1101a^4b^10
+414a^3b^11+101a^2b^12+14ab^13+b^14
Next question.... I think i understand this correct me if wrong: (2x+y)^4=2x^4+8x^3y+12x^2y^2+8xy^3+y^4 I don't think it is 2x^4+8x^3y+12x^2y^2+8xy^3+2y^4 but if it is tell me. Please grade me -0=2:2, -1=1:2,
-2=0:2. If i got any wrong please tell me what i did?

p=plank constant/wave length

plank constant = energy/frequency
wave length = c/frequency

p = energy/frequency/ c/frequency

p=energy/c

but energy=mc^2

so,
p = mc^2/c

p = mc.

According to this,

h/wavelength=mc

mass of a photon= hc/wavelength

IS THIS RIGHT ??????????

I have an idea on how to build a machine that uses a power supply that is unlimited,and free,and absolutely nonpoluting. This machine will use materials that are readily available,but cost money I do not have. I know it can be done,and the only thing I have is the knowledge.I need someone willing to work with me,who has the resourses,or the ability to get them.My idea is so simple, so unbelevable,I can not understand how it has not been done yet.Then again it most likely has,but not allowed by the govmnt.They could not make money. Coal and oil power would all but dissapear. They said men would never fly,go to the moon,or live with a mechanical heart. This will work. Does anyone know how to get help ?

Look the following reaction:
ZnSO4+2NaOH-----> Na2SO4+Zn(OH)2
In the above reaction ,look at the products:
here,why "2" comes after Na and before SO4(Na2SO4)
and "3" comes after "Zn(OH)2"?

Fact is the Earth evolves. And it takes Millions of years. Right now we are at that point again. History shows that something tragic will happen & destroy life. Will we see it coming? Will happen Today? Tomorrow? in 50 years? Can We stop it to preserve Human Life? How do you stop the most dangeruos place on earth (Yellow Stone Park - Reference: Discovery Channel) When that blows everything will go. It's about 100x more powerful than the one that killed the Dinosaur's. That's just 1 example. Maybe an Astroid. We've been hit before by my examples of Astroids & Valcanoes and it's destroyed life and created new forms of life. Earth does Evolve. It will happen.

A rectangular room measures 30 feet in length and 12 feet in height, and the ends are 12 feet in width. A spider, rests at a point one foot down from the ceiling at the middle of one end. A fly (food of food to the former) is located one foot up from the floor at the middle of the other end.
The OLD problem, as above, published in various math challenge books, and I see repeated here, as it probably will be again and again years from now, is to find the minimum distance between the spider and the fly, accomplished by "unfolding" the room and computing the pythagorean distance.
What will would probably be MUCH more of a challenge is to determine if the spider CONTINUES on the same direction, (an after dinner walk? :-) ), straight with respect to the "unfolding" of the walls, until (and if?) it EVER returns to its starting position, and if so, how far does the spider travel. Is there an analytic way to do this (preferred), or as an initial answer one could write a computr program?
