Thanks a bunch for all of the replies guys! Although I'm still not sure why the author used that as an example as it just caused confusion. I've decided to just move on in the book and try to not worry about that problem.:biggrin: Again, thanks for all the help!

Any possibility of someone expanding on this? I'm not that familiar with either of those and would like to see how the author can go from step 1 to step 2 in the above equation.

Hi all, I've been trying to get back into mathematics by teaching myself calculus. I've been starting with the book "Calculus Made Easy" and have been doing fine except for one little thing I encountered on page 57. He shows a mathematical proof of why the derivative of y = x^\frac {1} {2}...

Awesome! I think that pretty much clears up most of my confusion! :biggrin: The rest I can get from reading up more about the Hubble Sphere like you said. Thanks a ton guys for helpin me with this one :)

Ohhh, so they are still catching up to us! So, does that mean there's a space "behind" these CMBR photons in our universe where the CMBR is not detected? (like in my flashlight example) And the precautionary note about the universe, is that meant to say "The universe is infinite" or "We have...

Thanks! That makes a lot of sense that there isn't much to be seen anyways, since it is only 2.7 degrees K. man I'm learning a lot here and i don't want to stop :D so... Now my question is: why is that particular micro-wave radiation EVERYWHERE in space? Naturally in my head, I think of the...

That helped a lot! Thanks! But still...lol one more question: We can't see the microwave radiation because our eyes obviously were only meant to see the "visible" spectrum. But even though we aren't able to see the micro-wave radiation, it is still there, and shouldn't it interfere...

Ah ok, I think I'm starting to get it. But "radiation" is such a vague word. What exactly IS this micro-wave radiation that is left over, made of? I think that's the bulk of what I'm mainly having a hard time understanding.

From what I understand, empty space has a temperature of 2.7 degrees K? And that empty space still gives off micro-wave radiation from the big bang? Can someone help me visualize this? For me, the idea of empty space giving off radiation and having a temperature that isn't absolute zero is...

I hope I'm not misunderstanding your question, but if you are asking if that according to the Pauli Exclusion Principle that a certain electron's quantum numbers is the only electron in the universe with the exact same quantum numbers then the answer is no. I'm pretty sure the Exclusion...

Wow, thank you so much for taking your time to reply. This is definitely the advice I needed to hear and has given me much more confidence in being able to obtain my future goals. I'm currently reading and working along with "Calculus Made Easy" to hopefully prepare me for the Fall semester and...

In high school, I treated school like a joke. When I started college I did great the first semester, but in the 2nd & 3rd semester, I messed aroudn horribly. I had a 3.8 GPA in semester 1, after 2 & 3 I now had a GPA of about 1.8 I never knew what I wanted to do with my life, much less...

Wow, thanks for the positive responses!

I am an aspiring Physicist and I'm really interested in particle physics and Quantum Mechanics. I have been in college for 3 semesters now and have had no clue what I've wanted to do until I finished Kip Thorne's "Black Holes and Time Warps" and found out so many amazing things about reality...

lol @ Rut Roh Wow Javier, thank you soooo much! I didn't grasp it 100% but surprisingly I understood most of it! Thanks again! -Eric
