Diamond doesn't even melt, it burns. Even still the "melting" point of diamond is 4300K whereas graphite is 3948K

But is it the act of observing it that creates the uncertainty or is the uncertainty always there, regardless of whether we're observing it or not?

It doesn't seem accurate to just say "if I want..." What I want is irrelevant, I just wanted to know what science says it is. I think I got my answer though.

As far as I know a point in space is shown by it's t,x,y and z coordinates? Anyway it isn't so much how it's defined that I'm interested in, it's more about what a point of space is. Let's say we took a 1cm^2 region of space, how many unique points of space does this region have? What...

I used a circle as an example simply because it's easiest to draw on a piece of paper. A circle and a sphere hold the same principle that I was trying to explain. Doesn't matter now though because I understand what marcus, bapowell and viper were saying so it cleared up any confusion.

Now this makes sense and I remember a previous statement saying that a finite object cannot become infinite and vice versa. Also I am not familiar with limits but I was thinking about this as a physical idea, not so much a mathematical concept.

But that's the point... If it has an infinite diametre then its curvature must be 0.

So why does the curvature never actually reach 0 if the size of the circle is infinitely large? Because by saying that the curve never reaches 0 implies that you could, with enough time travel around the circumference of the circle and get back to where you started which would mean the circle is...

I'm confused, I thought this was the whole idea of infinity. ##\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\cdots=1## but the only reason it equals 1 is because it goes on for infinite. So if you're saying that a circle never becomes a straight line, is that not the same as saying that the...

Please excuse my ignorance on the topic but I just thought of something which seems to make sense to me but then again I have no experience in cosmology. Just some points I want to clarify. Because the universe had a starting point, can it's size be infinite? If so could the universe be a...

That's true it's sort of like a catch 22. However hopefully if we detect another universe and conclude that the MW theory is correct, could we then somehow indirectly prove / disprove quantum suicide?

I just stumbled across this paper and I'd like someone to translate it for a layman. Just a paragraph or so if that's possible? Basically I just want to know how true quantum suicide is. http://xxx.lanl.gov/PS_cache/quant-ph/pdf/9709/9709032v1.pdf Also can you explain what this video...

Yes, to clear the fractions. When I multiply each equation as you said I'll end up with \begin{array}{cc} 2x+4y-3z=4 \\ 2x-y+3z=6 \\ 5x-y+10z=5 \end{array} ?

In my book it suggests to try clearing the denominators first to make it easier. To do this do you just multiply each term by the lowest commom number? So in my case I would multiply the first term by 2 to clear the 2, the second term by 4 giving 4y, leaving the third term as it is and then...

Homework Statement Solve the following system of linear equations. ##\begin{array}{cc} \frac{1}{2}x+y-\frac{3}{4}z=1 \\ \frac{2}{3}x-\frac{1}{3}y+z=2 \\ x-\frac{1}{5}y+2z=1 \end{array}## The Attempt at a Solution Can I just do elimination by addition? So if I multiple the first equation by...
