>be me yesterday
>family is in town for Thanksgiving
>driving my half brother somewhere
>made a joke about the sun because it was shining in our eyes, mention nuclear fusion
>suddenly he says "supposedly"
>wat

So he proceeds to go on about something called Electric Universe Theory (I had never heard of it until then) and how I shouldn't believe all the "bullshit they teach you in school".

I pretty much respond with pic related and he calls me close minded. I say no, I'm gonna need some citations on that shit you just spewed, because scientific consensus says the sun and other stars are made by nuclear fusion.

So we finally get home and he makes me look it up on my laptop. So I put it in Google.

First three sites are .info pages and the fourth or so is a Rational wiki entry

Top kek

I call him out on his pseudoscientific shit and give him several refutation citations against his theory and he just gets mad, tells me I'm fucking stupid and doesn't talk to me the rest of the day.

My family is full of morons.

> My family is full of morons.

Most people are fairly dumb. Don't fall for the assumption that the average intelligence is in any way sufficient for the challenges facing Humans. Given the nature of our challenges, and given the clear incapabilities extant in the average person, only a few percent of people are able to fully face the present and future.

My dad always mentions popsci physics articles he has read to me. Since I'm /physics/ except he doesn't know much about physics so I tell him to just read about basic physics that he can understand before moving onto the 'cool' stuff.

Anyway one day when he was telling me one of these things I told him to read the chapter in feynman lectures on physics about gravitation. But he told me he already understood gravity and that it was caused by the rotation of objects. He refused to believe that any mass has gravity and that if he was in the middle of space and there was nothing around him but a spacestation it would be exerting a gravitational force on him.

I wouldn't say most people are dumb, they are just content with having no knowledge on lots of subjects.

The contracts are still up in the air. If you're on the fence about medicine, wait (if possible) to see what the monetary situation looks like.

Other than that, it's really a personal commitment to do more work than you get paid for (in terms of complexity, hours, emotional situation, etc)

What's the probability that a random alien fruit, provided it is carbon based, would be edible for us?
37 posts and 3 images submitted.
>>
Obviously there's no practical way to even ballpark this, but even if alien fruit evolved simple sugars that we could digest, chances seem high that the other junk it's made out of would be toxic or at the very least indigestible to us, causing diarrhea, defeating the purpose of eating it.
>>
>>7678735
there are plants on our own planet that evolved in the same environments as we did that will poison and kill you. This is why when hunter/gatherer tribes move into new areas, the safest food sources are fish and game, meat is edible as long as you cook it.

It is incredibly unlikely plants on another planet would be edible to people.
>>
>>7678763
This, basically. Life on earth evolved, as far as we can tell, in a closed ecosystem. If life evolved elsewhere, in a similarly closed ecosystem, chances are low that the two would be compatible. Unless life as we know it on earth is actually the only form of life possible, but that still doesn't guarantee that we could safely eat, digest, and extract nutrients from it.

Python. It's simple, open source (so we don't have to pay for a Matlab license), and flexible. Also, it's easy to teach to undergrads.

>>7678560
That being said, it isn't powerful enough to do certain simulations, so it isn't the only thing we use.

But you're right, I need stop being a dinosaur and switch to python... It's where everything is going... Any good resources to learn python for someone with a matlab background?

yet, even the askdarwinist website admits to the frauds and still hold to their belief in evolution.

You guys do know the antibiotic apocalypse is approaching? I'd say we've got another 20 years max of effective medicine. Cancer will be deadly again, no more operations, millions will die. There hasn't been a new class of antibiotics for DECADES. Indians and Chinese are mostly to blame for improper use and poor regulation.

Wouldn't the easiest way to fracture something be to use a double-toothed tool (Notched pickaxe, heehee) to create an interference pattern that will cause parts of the rock to vibrate out of phase with each other?
I was never terribly good at chemisty, but apparently fractures occur when something's structure slides against itself, and I don't think that a radial shockwave is terribly good for doing that.
Alternatively as a way to improve a pickaxe/pneumatic-drill if the vibration is more linear than radial would be to have two impacts, one occurring a tiny fraction of a second later.

hey /sci/ I'm an auxiliary professor from a Biology in a molecular biology career in South America (Argentina precisely), and wanted ideas and opinions on what kind of lab activities could be implemented for encouraging students to learn or get their attention.
Ive tried looking in US colleges websites for any kind of virtual board or something directed at students to see if I can find any info on what kind of practical activities were carried out, but no luck. I mean you enter my college web and in four clicks you are accessing all the info of the assignature, maybe cause public education here dunno.
An idea of mine was to obtain hometic mutants of Drosophila since we have a constant supply of flies (we grow them through all the year), but I dont know if there is a simple and economic way of achieving this. Well any other ideas or suggestions come in handy, we really are trying to adapt to this new kinds of students and modernize a little

>FACT: Harvard rejects literally hundreds of candidates with 1400-plus SAT scores and 4.0 GPA’s in favor of students with lesser academic achievements. The truly brilliant students are almost always admitted, but the other 90% of each class is comprised of students who meet a combination of factors, including intellectual ability, unusual attractiveness of personality, outstanding capacity for leadership, creative ability, athletic ability, maturity and motivation for a liberal arts education and geographic distribution.

Why do we take this shithole seriously lads?

>MYTH: Last year’s valedictorian wasn’t admitted and he/she was smarter than I am, so I don’t stand a chance.

>FACT: Maybe you offer qualities which the other person didn’t have – a superior creativity, leadership ability, motivation, athletic ability, etc. As noted previously, many factors besides intellect are considered. Harvard does not want, or have, a student body of “grinds” who are uncreative, plodding regurgitators of knowledge.

You're not an uncreative plodding regurgitator are you /sci/?

Grades aren't everything ya Dingus. So what if you got perfect grades/test scores? You don't stand out purely academically unless you ace every AP test even without taking the classes and you ace all your subject tests. Even that won't guarantee admission.

Have any anons found themselves obsessed with a particular area, say maths or science?

I figure it must be pretty fun, or at least interesting:

>mundane worries like money become background noise
>can't wait for every new day to practice and learn more about the area
>more constructive than television or 4chan
>spend vast amounts of time in the bliss of intense concentration

Of course, this state of mind isn't natural to me, or most people.

Do any anons have any experience with it? Does it just happen? Does it happen if you spend 16 hours a day doing something? Can it be cultivated.

I'd love to hear your thoughts, /sci/, although I imagine this thread will slide right down out the catalog.

Spent a number of years that way, on various topic. Ultimately burnt out for mostly unrelated reasons.

I imagine I could go back if I wanted, but that hyperfixation made me half mad at the same time. I definitely lost perspective and became myopic. Then I started lying without knowing it.

I have it too atm.

But it's more the drive to materialize a vision I have, which keeps me interested in math.

I see it more as a tool to create, so proving stuff when I don't need, but have to, does still annoy me but I know I have to do it in order to improve.

But when I stumple upon my own problems, finding the solution is as funny as playing a video game.

Sadly I now have stumpled upon a problem so complex, it makes me think I'd might not be able to contribute to its solution in my life, as I have imagined. that makes me kinda sad.

So if im not meant to be the one to use math for building machines, I can surely combine it with art to create something beautiful.

Hello all. I'm curious about how a theoretical physicist works. What do they do in a daily basis? I'm not talking about cream of the crop physicists, with worldwide fame. I'm talking about the regular theoretical physicist that you can find in any Physics department.

Another question, what kinds of jobs can a person with a PhD in Physics, with a theoretical emphasis, get in the developed world (USA, Canada, Australia, Europe etc)?

And lastly, why does a PhD in Physics is so much shorter in Australia and in the UK compared to the USA and other western countries?

Not many people have a PhD in physics so their aren't many people suited to answer questions like these. Just be patient OP. Also start this thread on /adv/ as well. Someone will at least answer parts of it.
>>
Well a theoretical physicist is someone who get's paid to research, so you're just doing research in academia, and unless you're a big shot, you're also teaching and supervising grad students, i.e. what your professors do.

If you have a phD in Theoretical Physics but aren't doing research, you're just going to be a guy with a PhD in physics that almost certainly ends up doing a job that has nothing to do with physics, e.g. wall-street quant, programmer, bar-tender (lol, yes I know a bar-tender with a physics phd). But chances are you will eventually find some kind of low to mid-level technical job.
