Maybe this will help: http://en.wikipedia.org/wiki/Binomial_series#Special_cases Good luck!

Hi, I have some questions that came up while thinking of this idea of parallel universes, I'm glad if someone could help answer these. 1. Assume we somehow discover another universe, does this discovery then imply that OUR universe is finite in size? Or is it still possible to have an...

But what limits us from not "extracting" more than just 2-3% of the energy? Is it limits set by nature or are the reasons because it's hard with current technology? This is very interesting!

Cool, thanks for the good links! I had no idea about this, and that so little energy is used of the fuel really suprised me. Is there any limit set by nature from the energy we can get from our nuclear fuel? Something like Bet'z law but for nuclear fuel. /Robin

This might be a retarded question, if so please forgive me I have no knowledge in nuclear physics. But is it possible to use the nuclear waste as some kind of fuel? If not, is it impossible due to laws of physics or just mainly due to impractical reasons? For me as a novice, the radiation from...

By the way, what do you think the future looks like for a career in nuclear medicine? I know it's hard to answer correctly, but what do you THINK? About 5 years forward.

Great, thanks for your informative replies. I had some questions in my mind before I came here to write them to you - but now, ironically, I've forgotten them... However I'll return when they come back. If anyone has anything more to add feel free too, I really appreciate it. Best Regards...

Hello I have a 2 more years planning ahead before I choose my major, however I like to plan ahead so I've come up with some questions. I've been considering studying nuclear engineering as my major degree when the time has come, and I wonder how the career opportunity is for working with...

Cool! Didn't know that! Thanks /Robin

Here is the best advice I can give you :-)! https://www.khanacademy.org/

Maybe this could help (which is still an active thread) https://www.physicsforums.com/showthread.php?t=683480

Thank you Marcus. It's actually a good point and something that I did experience last week. I discussed the hubble "constant" with someone and I said that the hubble "constant" is not constant through time :confused::confused: ? and noticed the very bad logic in the words that stumbled out of my...

I'm very well aware that magnitude and flux is not equal. Yet, thank you for your correction. I'm sorry I didn't know that the relationship held true between luminosity and flux, and not between luminosity and magnitude as I thought before. I also see on Wikipedia the relationship you...

I'm doing visual observations with my 14" dobsonian.

Nice! I always love to see results like this. I'm currently observing variable stars (not stars who vary due to transits yet :biggrin:) but in the future when I'm no longer a poor student I'll maybe starting doing the same as you just did!
