think if the quickest way between points a and b is a straight line and particle x moves between a and b in exactly 1 second using the course of a straight line, wouldnt particle z need to travel at a greater speed in order to travel as a wave and still cover the same amount of distance in the same about of time?? and an even greater speed for higher frequencies?

Instead of bringing along equiptment, to convert what is availiable on Mars, into fuel to return home, I propose to do the one way sacrifice, and bring along plant seeds, and small nukes, to drop into that Grand Canyon area, hopefully stirring up volcanic eruption at the core, and enough dust so an atmospere could form, without bleeding into space. This would warm and melt the ice, creating a mini Earth. plant life would thrive on the planets high CO2, creating oxygen to breath, rain clouds, lakes rivers...etc....and if the planet has no molten core, and is unable to have a magnetic field, than at least we would know for sure, and could plan space stations or "Plandomets" (thats the word dome inside the word planet, heh). I am willing to make the one way mission if somebody could connect me to the "Teraforming" Nasa folks.

If the person doesn't age at all relative to the people on Earth, (the whole Universe even), then would the Universe age infinately relative to the travelling person, in other words, get to the end of its cycle (if there is one)?

I remember in 1998/1999 i was in grade 6, and we were at a soccer practice with my school soccer team. I live in southern ontario (kitchener).
It was very cold, im thinking either oct before winter. and we were playing, when all of a sudden I looked in the sky and there was this HUGE ball in the air a fiery one. it had a HUGE tail and was really big. It looked like the size of the sun from earth as in how the sun looks to us every day.
and i remember i was like OMG is it going to hit earth? but it was going and going until it went over the forest and i couldnt see it anymore. My teacher even saw it, and was surprised.

does anyone know which comet this could have been?
im REALLY curious :S

What is the only positive value of b for which (x+b)^2 = x^2+2bx+b^3 is an identity for all real values of x?

---

If x + y = 1, x^3+y^3 = 19, find the values of x^2 + y^2.


please show me the step by step process.

Multiple mirrors not just one. Is there a limit to how high you can get the temperature? Can anyone give me an example like, "It would take 233 mirrors focussing on the same spot to make the temperature on teh spot 1000 degrees C"...?

Thanks for your answers ;)
