Double Major in ECE + ChemE may be theoretically possible.

I wonder if it can be done or not.

then also double minor in Math & Physics

It seems very suicidal.

Like combustive flight, rotating locomotion is separated by too large a valley in the fitness landscape for gene pools to cross, meaning it has a lack of useful intermediate stages.

How trustworthy is this guy/psychological theories in general?

I'm studying computer science at a great (top ten) uni in burgerland but got depressed by it all and have taken some time off to prepare an art/design portfolio for art school. It's a reputable one (think RISD, if any of you are aware of it), but I know it won't necessarily save me.

Pic related is telling me to suck it up and pursue being a tech yuppie in the bay. I have some friends there saying I wouldn't even need a degree to make ridiculous bank, but if I ever did want to kill myself it was debugging projects I could not care less for.

Denoting by N the total number of humans who were ever or will ever be born, the Copernican principle suggests that humans are equally likely (along with the other N - 1 humans) to find themselves at any position n of the total population N, so humans assume that our fractional position f = n/N is uniformly distributed on the interval [0, 1] prior to learning our absolute position. f is uniformly distributed on (0, 1) even after learning of the absolute position n. That is, for example, there is a 95% chance that f is in the interval (0.05, 1), that is f > 0.05. In other words, we could assume that we could be 95% certain that we would be within the last 95% of all the humans ever to be bien. If we know our absolute position n, this implies an upper bound for N obtained by rearranging n/N > 0.05 to give N < 20n. 60 billion humans have been born so far, so it can be estimated that here is a 95% chance that the total number humans N will be less than 20 x 60 billion = 1.2 trillion. Assuming the world population stabilizes at 10 billion and a life expectancy of 80 years, it can be estimated that the remaining 1140 billion humans will be born in 9120 years. So there is a 95% chance of extinction within 9,120 years.

Interesting probability puzzle I have been pondering:

You roll an unfair N sided die M times where M >= N. What is the probability that you will see every side at least once?

The probability of each of the N sides coming up are, respectively, [p_1, p_2, ... p_N]

Mfw pure math brainlets will argue over this answer when you can simply use a Monte Carlo algorithm to find the answer in minutes
>>
>>9004488
I thought it would be a cool exercise and I tried but what are p_1, p_2, etc. supposed to represent? You can't simulate anything if you don't know the probabilities of each side
>>
>>9004517
brainlet
it doesn't matter what the probabilities are specifically. [math]\sum _{i=1}^nP_i = 1[/math] is all you need to know.

Anyway, the probability of not seeing the ith side after M rolls is [math](1-P_i)^M[/math]

The probability of not NOT seeing the ith side after M rolls is [math]1-(1-P_i)^M[/math]

The probability of not not seeing all the sides in M rolls is [math]\sum _{i=1}^n\left(1-\left(1-P_i\right)^M\right)[/math] which can be rewritten as [math]n-\sum _{i=1}^n\left(1-P_i\right)^M[/math]
In other words, that's the probability that you'll see every side after M rolls.

So my grandfather died and I was going though his stuff with my dad. Grandpa was a school science teacher and principal, and I found a couple of pretty cool fish fossils that I'm gonna keep and display in my house. I don't know anything about them. I've done some googling, but it's hard to even know what terms to search for.

Can anyone help me identify they are?

What I know:
>Found in American southwest (Utah, I think?)
>They look like some kind of fish
>Pretty sure they're 2 sides of the same fossilized animal(?), so it's like a mirror image

Looks like a crustacean from the paleolithic era. Try giving it tree fiddy.

But seriously, this is probably from the Eocene. It's gonna be difficult to classify the exact species though because we can't see any of its dorsal or pectoral fins.

For masters you don't even need research experience, it is just a bonus. It is good to have as it makes RA positions easier to attain earlier though. Your letters, GPA, and GRE will matter as well.
