In America the polynomial long division is done by this way:
http://www.purplemath.com/modules/polydiv2.htm
but in my country the format is different:
the polynomia who should be divided appears in the left-hand and the polynomial who is divided appears in the right hand. Also the quotient appear under the this last polynomial.
Does this approach change anything?

Bit of a specialist question.

Most commercial vendors info tells you if their antibody works on western blots or for immunohistochemistry or for immunocytochemistry.

Why should any antibody work for one of the above but not for all?

What properties of the antibody cause this difference in efficiency in various applications?

I hear that they are building a nuclear fission reactor in France. The benefits to our society would be immence, but if it backfires could it possibly destroy our exhistance?
I mean if it works we WILL have discovered a endless fuel source and our reaches will be greater than ever.
But technically couldn't it implode on itself destroying the facility and possibly the world?

Express log (a/b) - log(c/b) + log(d/c) - 2 log(a/c) + log(a/10d) as a single logarithm and simplify.

of eyes and being gay.

I dont want to offend anybody gay or cross eyed but i think:

(And let me add that i am definitely not a homophopic person with many gay friends and i believe this is genetic.)

I think : A large number of gay guys have a certain look where their eyes are some what cross...or distance between their eyes are somewhat unique?? This is just an observation.

I do realize there are gays with perfect eyes but there is a large group with a different eye distance.

I think this may be genetic, just like woman with longer ring finger than index finger being better in sports. (type.)

Please dont make smart aass comments.. I am trying to find out if anybody else observed this... Thats all. Just checking the collective wisdom and knowledge.

And i dont believe all cross eyed people are gay either... (so save your breath.)

For example, I need number pairs, using numerals 1,2,3,4,5,6 and using each numeral twice. Each sequence should have six pairs. I know this likely doesn't make sense, but I'm math-illiterate, so please forgive me! One example would be 1&2, 3&4, 5&6, 1&3, 2&5, 4&6...thanks.

A look at the surface of the sun in Ultraviolet reveals a complexity that many people believe could support a computational engine several orders of magnitude more powerful than the human brain.

This implies other sentient stars, and my personal belief is that our sun has a bet with his star buddies on who can create the doofiest life form.

If that is true, and if we are it, IS HE WINNING?

The Biology Department is considering purchasing new microscopes from Schultz Optics. The diameter of the field of view using the high power (40x) objective is 0.35 millimeters (mm). If you were to use this microscope, and under high power found that the longest dimension of a particular cell fills 1/10 of the diameter of the field, what is the size of the cell in reality? Provide your answer in micrometers (um), rounded to the nearest whole number. Do not include units in your answer.
