Why do so many physicists say that the linear algebra is the most important branch of math to physics?
In my calculus class, I can see applications in all most all of the concepts we learn to physics. In linear algebra, I have yet to see even one application to physics aside from simple vector geometry, which most people know without ever taking physics. Please tell me, how are vector spaces, bases, dimensions, rank, determinants, eigenvalues/eigenvectors, and linear transformations

(a 4 coefficient is in front of the neutron particle meaning 4 neutrons) what do I place as X in order to balance the equation? I thought I had to add 3 alpha particles but apparently that's not it. Please help.
Can pGEM-T Easy Vector JM109 cells take up multiple copies of the Plasmid?
I am using JM109 cells and the pGEM-T easy vector system II to clone a mixed microbial community for sequencing and I need to know whether a sinle copy or multiple copies can be taken up by each competent cell because this will impact on my ability to sequence from purified plasmid from 1 white cell.
rates question involving system of linear equations.. please break it down for me?
A cyclist travels 60mi in 5 hours going against the wind. She travels 100 with the wind in the same amount of time. What is the rate of the cyclist in still air and what is the rate of the wind?
What is the first step in solving the equation 88 = 13 + 5x?

What blood type am I? Father is AB+, Mother is O+.?
Mt father is blood type AB+ and my mother's blood type is O+. I know that in this situation I'm either A or B. But I was wondering 2 things. 1. If I'm A for example, am I positive since both of my parents are or is there still a chance for me to be negative? 2. Is there more of a chance to have A than B? Or visa versa?

A gene in cattle controls whether horns develop or not. When cattle without horns are mated together, none of the offspring ever has horns. A male with horns is mated with females without horns. If half of the offspring have horns and half do not, what is the conclusion?
a) the male is homozygous dominant b) the make is homozygous recessive c) the male is heterozygous d) only males
How to balance acidic reaction using the half method?
KMnO4 + H2SO4 + NaHSO3 -> MnSO4 I get stuck when balancing the overall charge using electrons on the 2 half reactions. If someone could please explain the steps needed to balance using the half reaction method and explain to me how we find the overall charge on either side of the arrow when balancing with electrons, I'd really appreciate it. Thanks I don't get
I am looking online for coenzyme Q10. I visit iherb.com often. On that site there are so many coenzyme Q10. I do not know what to buy or what to look for, in terms of amount. What is a good price for it? I do not want to pay too much or not enough coenzyme Q10 or too much in my system.
Why is there an option to search for medical questions but not nursing?
Nurses, both bedside RN's and Advanced Practice nurses (NP's CNS's) are often overlooked when discussing health care topics. Why is this and what can we do to change this on yahoo? I think there are plenty of nurses out there who would like a forum of questions of their own, and plenty of people who want to hear what they have to say! Thoughts?
I have searched on the internet and not found much information on this. But I want to know about how much job security do doctors have. I mean because of the rescession can hospitals or clinics lay off doctors? (because people don't have insurance without jobs) How common is this?
Are there doctors who are unemployed and found jobs in other sectors. (like doing other lower paying j
Help me find the concentrations of A- and HA when given pH and pKa?!?!?!?
At pH of 6 and pH of 9, what are the concentrations of A- and HA when the pKa is 8? I know the formula, but the log function vexes me, and I can't figure out how to solve these on my TI-83... PLEASE HELP!!!! )
How do I rank acidic compounds w/o pH or pKa values?
I'm trying to rank this compounds from greatest to weakest acid based on the compound itself. A) NH3 B) H2O C) H2 D) HC (triple bond) CH E) CH3OH F) H3O+
