|
 |
So dad's friend brought some old laptop, and said that I see if it can be fixed, because it's broken.
Ok, since everything was working (disk and the fan), but there was a black screen, I thought, ok, maybe it's the screen. So I plugged it in my monitor. Nothing.
Hmm ok, let's take it apart and see what's underneath. So I disassemble the whole thing, and leave just the memory and the disk, and again, plug it in (who knows, maybe there was some short circuit with keyboard, or some other line). Nothing...
Ok, but, what's this blue light next to the caps lock that seems to be blinking in strange intervals?
Oh there are codes when your notebook is broken....
...
...
AND I JUST TOOK THE WHOLE THING APART!! -.-"
It appears that the PCB is dead (5 blinks). Dad's friend said that I try and sell it for pieces. Disk works (I plugged it in my comp), memory can be sold, and the screen seems to be working...
Sometimes knowing things can totally cloud the simple things and solutions...
I remember when the doorman at my uni gave a simple puzzle to me and my friends. And we all started to think about integrals, geometric series... Needles to say the answer to the problem was just a simple multiplication.
But that never came to our mind. As you start to know more and more you start to complicate even the simplest things...
Funny, eh?

So true 
Hard to see the obvious when we are looking beyond it. |
Exactly. Ban higher math in schools! |
Yeah!
Oh, wait... o.o

Well I use way more higher math these days, so I can't say that learning that was useless xD

Do you use it at work or do you use it for calculating probability of getting cancer by eating a burger?  |
If by work you mean my studies, then most certainly
And you can't do physics without math so

You serious?
Because I could go on and on and on
One professor from MIT said: If you can't do a Fourier transform of sth it's not real math xD
If you need any help just PM me

Something with two trains going towards each other and a bug iirc... It was really simple actually, but we all started to complicate it.

Yeah would be interested as well. Recently encountered FFT for prime search purposes and although I have had a bit of education in FT, to try to understand the higher math almost 20 years later again, is not that easy.

I had an exam that I got 0/100 on. I scan it and sent a copy to him.
He solved all the answers AND wrote explanations on how to do each question.
Plus he gave me few cool links on fourier transform and cauchy reside theorem to read about it!

I can't even remember why FT works :/

Because it does! 
J/k
math behind FT is not that trivial, so to try to explain it in layman terms would be rather interesting
EDIT: Oh and I fully support besthijackers idea about me as president.
I won't let you down! And you'll all get free healthcare, dingocare!
*dingocare healthcare is basically you getting eaten by dingos xD*

I think it was sth like this:
Two trains are like 200 km apart and leave the station at the same time with the same speed of 50 km/h, and a bug going 100 km/h is in the middle and starts to go towards one train. And the question is what will be the length of the traveled path of the bug before the trains meet?
I think it's that, if I haven't forgot sth...
Oh and you assume no friction, and perfect 'elastic' scattering of the bug from the train You know, your ACME conditions

Two trains. Leaving two 200km-apart stations at the same time. Going towards each other. Velocity of both is 50km/h. A bug right in the middle heading the direction of one of the trains (doesn't matter which one) at 100 km/h. Isn't it asked the traveled distance of the bug right at the time they meet?

Well yeah. What is the distance traveled by the bug, until the trains meet. So the bug goes from one to another and so forth until they meet...
