The Bulletin of the Atomic Scientists, which created the Doomsday Clock in 1947 to warn the world of the dangers of nuclear weapons, advanced the clock to five minutes until midnight. It was the first adjustment of the clock since 2002

Wow. Now we are going to take the theory of global warming into account when adjusting the doomsday clock? Aside from this (the clock) still being one of the most egotistical and idiotic creations of the human race, at least in the old days it was a symbol of a desire for peace and security. Now it's going to be the global equivilent of the lifetime movie of the week? Why not add cervical cancer and violence against women to the list and bump that clock up to midnight? Does anyone really cringe and cower in fear when this clock is moved now? If so, how do you feel now that it's used for the flavor of the month cause?

explain how a 2:1 phenotypic ratio for a given locus with two alleles (3 possible genotypes) is produced for one trait, yet the same locus simultaneously reflects another trait (lethality)with a phenotypic ratio of 1dead:3alive.

Hello. I am stuck on a calculus problem and hope someone can help me. I was given a function for the value of a stock [ V(t) = Ke^(t^1/2), where K>0] and alternative investments [ A(t) = e^rt ]. I had to calculate the instantaneous rate of change for each, which I did, and also calculate the optimal time (t) to sell the stock. I cannot figure out this last part. How to I calculate the optimal time to sell the stock? Is it when V'(t)/V(t) = r? I guess I'm confused on how to relate the two results to find this? I tried setting the instantaneous rates of change equat to each other to find t, but the result didn't make sense: (1/(2(t^12)) = r. I tried to plug in an interest rate and got something weird. Can anyone help me?

Hi there I'm looking for a very good book on mathematics. And i will like the book to contain the following subtopics: Integers,natural numbers,irrational and rational numbers,fractions,polynomials,all grade equations, trigonometry, complex numbers and so on.

Then secondly any technical books that involves information on circuits and how to manipulate them with calculations. The book should have information on Coulomb, Kirchhoff principle, Joule,Ohm, paralell, series and everything that has to do with calculating circuits.

What will be the best books to get based on these information and from what site can i get them.
Both books should have detailed information about the information requested and easy to understand.
Thanks for your help!
