Any two rationals have an irrational between them and any two irrationals have a rational between them, so the number of irrationals and number of rationals must be the same.

Quoted By: >>11160124

You can't know an electron is there without interfering with it because the only way to know an electron is there is to use instrumentation that interferes with it. And it's physically impossible to see an electron without using that instrumentation. So yeah if you could magically see electrons then you probably wouldn't interfere with them, but it's not physically possible anon.

>> No.11160124

so the electron doesnt know you are watching it...

>to use instrumentation that interferes with it
are you serious? is that all it is? what is all this schrodinger bullshit

>> No.11160145

the thing you're complaining about is actually just another instance of a very bad way to name something, your complaint has nothing to do with the concept itself, only the word

"observation" actually means "interaction" because you can't observe something without interacting with it and though this is negligible in everyday situations, when you're dealing with objects the size of small molecules or smaller that becomes overpowering

This one seems to have been answered in /mg/.

>>11151710 [Binomial theorem.]
We can interpret the standard binomial formula

as a Taylor series expansion in x (for a fixed n), which is valid even when n is not an integer.
For example, when n = -1 this becomes
1/(1+x) = 1 - x + x^2 - x^3 + ...
and you may recognize the geometric series by making the substitution .
A common application of this is in calculus, where you can rewrite the integrand as an infinite sum (ideally a polynomial in x) and integrate termwise.
The catch, of course, is that this is only valid for x when the series converges, which is why we're interested in the range.

E.g. for the geometric series example above, the range of validity is |x| < 1, which is unchanged if we substitute with -x. But if we substituted , say, this would shrink the range of validity to |100x| < 1 i.e. -10 < x < 10.

>> No.11160173

Errata: Last line should be -1/100 < x < 1/100.
