/sci/ - Science & Math

Hey /sci/ just wondering when you should consider yourself a scientist? I know some people don't consider you a scientist until you've written several papers, and have lab of your own. Then others consider it to be when you start using the scientific method in everything that you do. I was wondering what the general consensus is on this?

Okay so im redoing some of the underage b& level math and I seem to do everything fine except one thing, I remember these bugging me when i first took algebra 2 and I cant for the life of me do them, it's like a mental block.

It's just factoring huge polynomials, like this one with a 5th degree. x^5+x^4-16x^3+4x^2-80x. How does one approach this the simplest way possible.

So, Imagine we isolated two populations of humans, both from the same gene stock, in identical enviornments.

How long until they speciate?

more like inventor, yes! he has a wonderful mind to create all does invents but to be one of the greatest scientist you need to have a free mind and always analyze thing and prove new things so I will go with Carl Sagan! to have a scientific mind you first need to question everything

I am having a discussion with my young earth creationist parents about whether or not there is a god or not this Saturday. I know they are going to bring up irreducible complexity an I am pretty sure I know how to refute it, but wanted to see what /sci/ thought. I am not a scientist (though I fucking love science) but I think I have some basic understanding of different "sciency" things.

The example they will most likely use is the eyeball, saying "How can the eye have evolved, you can not take away any part of it and have a useful eye, therefore it can't have evolved and was designed by god". Isn't the biggest flaw with this argument in the fact that they are assuming each part of the eye came into being in its current state at once and that the evolution occurred like
Stage 1: Eye ball part 1/5
Millions of years later
Stage 2: Eye ball part 2/5... etc.

When in reality it was all five "parts" gradually evolving at the same time together. I am not very good at explaining things sometimes so hopefully this makes sense. A thanks in advance for any who respond with a thoughtful response.

In the event that they all aren't hoaxes, failed missile launches, etc. they're more likely to be transhumans from tens of thousands of years into the future coming back than aliens.

Dear /sci/,

I'm used to using a unit circle for trig,
but my professor warned us that on the next test she may not use it and we will have to
determine the radius. How would I go about doing that?

Also, having trouble with a population problem (don't try solving it until you see where I'm having trouble):
Population = P(in thousands)
T = 0, representing year 2000
The equation for determining the population is:
P(t) = 103e^kt

Find k for the year 1985.
t = -15

* 72 = 103e^kt
* 72/103 = 103e^-15(k)/103
* 72/103 = e^-15(k)
* log(72/103) = log(e^-15(k))
* .3581 = -15(k)
* .3581/-15 = -15(k)/15
* .0239 = k

Now that I have k, it asks to predict the population for 2020.
How do I set this problem up? Would I still use 72 as P? Doesn't make sense to.
I set it up as 103e^(.0239)(20) but don't know what else to do.

Any help would be MUCH appreciated!
