I'm struggling to choose between either becoming a chemical engineer or a bio-medical. Both pay well so that's not an issue. I guess I'd just like more information about them or other types of similar engineering. Thanks all

civil, chemical, mechanical, or electrical, if you actually want transferable skills for a variety of induatries. worst thing you can do is only make yourself available to one or two.

Does /sci/ agree with him?

>>7717898
Well, it's by definition not science, so he's right in that regard.
As for the computer part, maybe? CS majors tend to know jack-shit about computers and instead just know how to purely code, so I guess that's right.

What if it was renamed to computing science?

Why not make new water towers taller than needed and use them for pumped storage hydroelectricity?

Because the water has to be pumped up there in the first place

Liquid water flow has terrible efficiency and there are countless better ways to store energy.

Look up Dinorwig power station. It pumps water up at night during cheap rates and releases the water during the day to meet peak power demands.

Hi /sci/, /tg/ here

Math question; mostly because I'm too dumb to remember how binomials work. Not that I was ever particularly good at those in high school to begin with..

How do I find out how many six-sided dice you roll on average before you've rolled one number twice? (looking for 1, but which number it is shouldn't matter for the math afaik)

The answer to the problem itself would also be greatly appreciated.
>>
Hint: If you rolled seven six-sided dice, what is the likelihood they will all show different numbers?
>>
>>7717636
You're not using a binomial distribution to solve this.. You're using a geometric distribution..

Let's suppose you roll:
$X=i$ for some i = 1,2,3,4,5,6

Then the question you want to know is how many times should I roll on average to get another i?

Well, assuming the die is fair:
$P(X=i) = \frac{1}{6}$ so
$P(X \neq i) = 1 - \frac{1}{6} = \frac{5}{6}$.

The geometric distribution models the number of times an experiment must be...
>>
>>7717678
I need to correct this I think..

I believe $k = 0,1,2,3,...$..

Sorry.. I'm just waking up.

In most regions, barely any beyond the most base forms of intelligence. The only thing keeping this grand machine halfway functional is sexual selection. Women and men who are either intelligent enough, or hardwired with a bias towards choosing partners who are highly functioning.

If I compile a computer program (say written in C#), what does actually physically happen on the harddrive and how is this achieved? Some physical elements must be switched right?

(I'm thinking about this in part because I want to know why people are coming up with programming languages for quantum computers now, what it means to set up the computer and how it's eventually done.
>>
>>7717455
>what does actually physically happen on the harddrive

The hard drive stores the data for the program. Processing occurs in the CPU. A program may or may not write data back to the hard drive (i.e., saving a file), but the program data itself generally remains intact.

Your human readable code is compiled into a binary code composed of machine commands that the CPU can interpret.

This code is a stored as a data file on your HD, which means either as magnetic charges or whatever SSDs use nowadays.

No. But high temperature aluminium explodes on contact with water. Aluminium from the jet, water from the various services. Chimney conditions heating the Al.

Jet fuel does not melt steel beams, however it can easily turn 200,000 tons of structural steel and concrete into a fine powder from the top down as well as laterally ejecting steel debris hundreds of meters.
