Any comment on his list? Items you would reformulate, combine, add or eliminate? Is this checklist a good schematic of the challenges facing theoretical physics at this point in history? I find it helps to have memorized so I can use it as an informal gauge of progress and relevance. One...

Hi all, I've finished a hypothetical problem in which I have determined the optimum damping ratio $\zeta$ for a specific system. This $\zeta$ value (0.265 in my case) minimizes the peak force transmitted through an object. My next step is to take this $\zeta$ value and find some sort of...

Hi Is there a formula which predicts at which temperature a gas condenses to a liquid ?. I think its called the critical temperature. I've found out thay C02 is 31C and Nitrogen -178. If not a formula can someone point me to a list of gases with info. I'd be quite interested to know...

I'm studying for an introductory C++ programming course and I'm trying to write the code for a doubly-circular linked list. To keep it simple, I had written my list to be tailored to that of a wedding dinner guest invitation list. Hence I didn't use templates at all. I've attempted to compile...

i was told to build a method for which if we find the asked value in one of the links we return the previous link i have built a method that supposedly does it the problem is that i was told that this code is wrong because we need to check the "this" link seperatly from the FOR loop why is that...
