Is PCR fun?

Today I got an offer for an undergrad research position (or the equivalent thereof in my country). It's a project with the goal of finding good primers for a certain type of HPV. I would be doing some desk work and lots of PCR for about eight weeks during the next summer.

Should I do it?

The alternative is looking for another reasearch project but most of them are just deskwork. It's also probably the only time in my life I would be working in a lab, so it'd be a new experience.
>>
>>7722305
It's an interesting concept. but doing the reaction is not fun. you're going to be doing the exact same thing many many times.
>>
>>7722305
That being said if you're in your undergrad, doing lab monkey work is really good for your career.
>>
>>7722308
Exactly. As an undergrad, though, it might be fun at first, but it'll quickly become dull.
But I prefer doing it over desk work, for sure.

guys right now I'm writing finals in my University, so can you help me solve some of the easy math problems? So here is one of them for example

6. We have $\displaystyle p(x) = g^2(x)f(x)$. So $\displaystyle p'(x) = 2g(x)g'(x)f(x) + g^2(x)f'(x)$ which implies $\displaystyle p'(-1) = 2g(-1)g'(-1)f(-1) + g^2(-1)f'(-1) = 2(3)(5)(4) + (3)^2(1/3) = 123$

Could the reason why no one knows what happening to the factors of a number when adding 1 be because we defined x^0 = 1 ?
>>
>>7722003
>defined
x^0=x^(n-n)=x^n/x^n=1
>>
>>7722054
What is the difference between this and this:

suppose that a = b
then a2 = ab
subtracting b2 from both sides gives us a2 – b2 = ab – b2
factorising gives (a + b)(a-b) = b(a-b)
dividing both sides by a-b gives a+b = b <- Here is the problem, we are not allowed to divide by zero!
But also a+b = b+b = 2b, so 2b = b. Dividing by b gives 2 = 1

We are not allowed to divide by zero because it results in shit, yet we are allowed to exponentiate n-n which also results in shit. What am I missing?

Hey /sci/! To show how intellectual you are, I want you to propose ways to make infinite energy.

>>7721989
we can't have that even in theory retard.

now making a shit ton of energy is something else, so nuclear is the way to go. harnessing atomic forces is the best way to obtain energy. we might find new elements work better than what we currently use, but other than that i see no other solution we can exploit

Because it would infer that if consciousness is universally derived, then it is universally manipulating.

e.i. the universe is consciously participating in itself. Yet, that is why we have god, because... spooky ramifications.

>>7721982
Look up Immanuel Kant and categories. In short: free will, causality, laws of physics, etc are categories through which you perceive the world. You can never achieve objective knowledge of the real world, but only subjective knowledge of the world you perceive. Therefore everything you experience is real for you, and that's the farthest you can go, so if you experience your will as free, your will is free for you.

>>7721998
Yet, subjective knowledge is not objective knowledge by discretion of the synthesis.

Here's a fun science question:

I am a male who is about 20 years old, and since around the age of 16 I have been able to cum as many times as my cardiovascular system and muscles will allow, over and over again, with no refractory period to speak of. Even when my penis eventually ends up completely flaccid, I can still coax more orgasms out of it if I have the strength left. The more times I cum, the better it feels. I used to count my orgasms when it first started happening, but once I regularly began to push the 20+ limit I stopped. I am able to orgasm multiple...

Well before someone inevitably goes into specific benefits and details, you need to ask yourself:
What is the point of doing anything? If we're not willing to set the highest goals for civilization then why set any?
