Am i too dumb for university?
I had my intelligence tested as part of an adult ADD diagnosis (WAIS) and found out my mathematic intelligence is in the 120, rest of the performance (logical etc) around 110-115 and verbal merely a 100. Obviously I always knew my intelligence was limited compared to some of the smarter kids but I passed secondary school without any effort

the real shocker was reading more about it and apparently the average IQ for BA graduates is 115 and for CS majors (which I wanted to study) 123

Am I simply too stupid, much lower than average? Because of my ADD i've been an underachiever all my life so i don't have any confidence to even bother trying for the entrance exam

Are there any CS majors here with average/slightly above average intelligence here who can answer whether it's encouraging or finishing off my poor dreams?

You should be fine. You'll have to work harder than the smarter kids and you'll never be top of the class but really a person of average intelligence can pass a first degree if he's prepared to put in the work.
>>
>>8803337
Here is a reality:
Universities will accept people much, much dumber than those averages. In fact, they accept complete 80 digit IQ cavemen.

So you have to take that chance and then get in. Take a strong first semester and see if your caveman brain can adapt and if you can then congrats, you will get a degree.

If you can't live through that semester then you lost 6 months of your life but hey, you are young and stupid so it is not like it counts.

What would be an appropriate profession for someone with an IQ slightly above average say 120. I'm interested in medicine, can i become a good doctor with this kind of IQ?

In medicine I hear memory is more important. I'm not sure how important IQ is. My IQ is only 134, but it's pretty clear I'm way better at math than most everyone else on this board.

why the fuck does pascal's triangle correlate with the coefficient of terms in binomials

>>8802853

>>
>>8802851
the rows are calculated using the same operation you could use to calculate binomial coefficients.

Imagine finding (1+x)^k by expanding (1+x)^(k-1) and then multiplying it by 1+x, and collecting like terms.

When you collect like terms you're adding two consecutive coefficients from the expansion of (1+x)^(k-1).

Just like when you find the kth row of Pascal's triangle you add two consecutive entries of the k-1th row

lol

in the context of computer science, 5.0 != 5
one if a floating point number, and caries the necessary information to distinguish it as such. the other is an integer and carries less information, and can be manipulated in simpler ways.

No. Everything in math is a set, and those two sets are not equal.

In number theory, my prof made a point about us not using equality between members of Z and Z/Z_p.

Do these things even do anything useful for their ecosystems or do they just go around leeching off everyone else? You always hear about bacteria being decomposers and fertilizers that benefit other species, but last I heard these guys don't even eat. Are they really such pests or do they have an ecological benefit?

Nobody is advancing technology with the pure intention of benefiting mankind. Since Tesla, it seems like his quote about wandering though equations and coming out to something that has no relation to the world is coming true. Science is just a circlejerk of deception now.

Hahaha no, it will never be worth to help other useless brainlet faggots in the world.

One should be able to work for it, since no one deserves anything.

But too bad some retards are still feeding little niggers in Africa and yet they don't know how to use a fucking condom.

The only people that should be benefited from modern science are the scientists themselves and the rich people that are supporting the projects.

Which is heavier; a kilogram of lead, or a kilogram of aluminium? Assume normal atmospheric conditions on planet earth.

I've asked this question to a few of my friends and one co-worker, and as soon as I suggest that kilograms is not a measure of weight, their capacity for arguing seems to dissipate into thin air. The typical answer is "a kg is a kg, they are the weight".

Apart from a lack of social skills, am I an idiot for believing that the lead is heavier?

Pretty much. This depends on the mass-density-volume relationship. Lead is a denser material, so for equal masses of lead and aluminum, the lead will occupy less volume. They have the same mass, though, and therefore require the same force to move (barring effects of increased drag due to greater volume, friction, etc).
>>
>>8801563
Depends on how you measure it

On a scale in a room filled with air a kg of lead will apply a slightly higher force, as it displaces less air. Then again, that will be a tiny difference, and if you measured to that precision you'd be measuring in a vacuum anyways.

Think about this: If you measured underwater, which would be heavier? The lead clearly. Then again, if you wanted to weigh them to abotain mass, you would use a space that has been emptied of water. Same in our atmosphere

It's really more of a gotcha question than anything of actual interest
>>
>>8801563
1 kg is a kg, if you multiply it with the graviation on earth you got the same 9.81N for each of them. But, lead has a higher specific density than aluminium, that meand more static energy is concentrated to the same volume as aluminium. if you look at ther molecular weight or better their atomic weight you can also see that Lead is 7.7 times heavier than Aluminium. But at the end 1 kg is 1 kg and has the same force on earth (even 7,7 times more Aluminium atoms are needed for that).

Wow, I actually did not realize it's that well-regarded; there are people around me getting Amazon, Facebook, and Apple, so I just wanted to make sure I'm not making a mistake by going to a non-big four. Thanks for your input.

Do they just read a bunch of scientific papers every now and then or is there a more structured and standardized approach?

There are lots of services which aggregate new information and provide summaries, from something like a clinical review in the NEJM to speciality specific publications.
Unless you're in a very small sub specialty it's not really possible to read all the new research being published.
In most places doctors do official CME (continuing medical education), basically where a licensing organization certifies courses, workshops etc which count for time spent updating knowledge.
>>
>>8799570
They don't. Whenever a patient comes in with unknown causes of weird symptoms they just guess until they get it right or until the patient dies. Bonus points if the patient has 2 or more causes of their symptoms.
>>
>>8799570
It's a requirement
CMEs are required by all states
And doctors must pass national boards every 10 years to remain board certified

The national board requirements utilize up to date info, a doctor whom didn't keep uptodate would have issues passing boards based on knowledge 10 years old.

Though, this requirement is being heavily lobbied to end, as specialties such as internal medicine (whom a growing majority are becoming hospitalists) only deal with medical wards or work as intensivists on the units, but the boards continue to demand knowledge of obstetrics (despite OB hospitalists becoming more main stream)

tl;dr they can lose their credentials if they don't keep up to date, and hospitals begin to revoke privileges when this happens

Why do people keep going to universities when pretty much anything you'd like to learn is available on the internet? Pic unrelated
