i read some interesting article.here is a part of the article: "Moreover, the S.I.V. (Servizio Informazioni del Vaticano) was informed during the meetings (of the aliens) with Pope Pius XII of the approach of a celestial body to the solar system in which resides an advanced very warlike alien race. It was during the analysis of certain data from the Alaska radio telescope that we discovered a photograph of a huge planet getting closer to the Solar System". its from www.ufodigest.com. what do you think?

I'm reading ahead for my physics class tomorrow and positrons are mentioned. They are described as "antielectrons" - exactly the same but with an opposite charge. So, are positrons basically very miniscule protons?

If a positron and electron will annihilate one another, why won't a proton and an electron annihilate one another?

What keeps protons and electrons apart anyway? Protons repel each other (like repels like) but why are electrons always found in an outer shell. If opposites attract, shouldn't they be with the protons?

What are the advantage/disadvantage between Michaelis-Menten,Lineweav... Plot to get the Vmax and Km.?
i have read from internet, and know that Lineweaver-Burk Plot will suggest some inaccuracy in the determination of the Vmax and Km, but why we still use it, i think that it must have some advantage to use Lineweaver-Burk Plot. so need some one to tell me? sorry my english is not good enough.
