The discussion centers on the debate over whether anyone can aspire to be a physicist, with references to Feynman's views on hard work and dedication. Participants argue that while some individuals may struggle with physics due to various factors, including lack of interest or prior knowledge, it is overly simplistic to claim that effort alone guarantees success in the field. There is acknowledgment that innate ability plays a role, as some people may face insurmountable challenges despite their efforts. The conversation highlights the importance of persistence and the varying experiences of students in mastering complex concepts. Ultimately, the consensus leans towards the idea that while dedication is crucial, not everyone possesses the same capacity to excel in physics.

No. Anyone can grasp the ideas involved, but I think the notion that anyone can get past the math needed to be a physicist is incorrect. As a physics student, I worked my butt off just to be above average. And this stuff is far easier for me than most people I know. There are people who struggle just to get past one or two algebra classes for their majors. I know. I tutored some of them. And I was often struck by the difficulty they had doing things that seemed obvious and simple to me. So I think the claim that anyone can do this shows a clear loss of perspective - too much time spent in the ivory tower!

When I first started algebra, the simplest ideas were difficult to me. The negative sign in front of parentheses changing the sign of every term inside the parentheses was just not making any sense to me. And people describing it by saying there's an implicit -1 in front of the parentheses just made it more confusing. At that time you definitely would've said that I'm just not a math person and just like one of the people you tutored.
Now several years later, I've taken 3 calculus classes, linear algebra, differential equations, and aside from calc 2, they were all pretty easy for me.

If I may say something on a personal note here, I find that physics is harder than the math as used in physics in most cases. I wouldn't say math is what is necessarily obstructing people from learning but rather the physics. Whoever went into an honors mechanics class and thought "boy this basic calculus is hard!" vs "boy applying the various physical concepts and approximation / dimensional analysis tools readily to problems is hard!".

I remember grade 11 math (my last year of forced math) a student commented to the class and teacher that algebra is useless to him, he will never use these equations to calculate stuff. blah blah blah.

The teachers response was along the lines of It's really important to know math, and it's part of the curriculum.

An unconvincing sell in other words

At the time I agreed with the students comments, it did seem stupid.

Years later I realize that The teacher was actually teaching us a new language. A very specifically designed language of absolute logic. A language that describes some of the most fascinating physics.

I woulda tried harder then, if I had known the language/communication perspective of math.

Those who think "intellectual" capacities are in some deep, mysterious ways different from "physical" capacities (like dexterity, capacity for swift acceleration of the body etc.) or "aesthetic" capacities (like musicality or an eye for visual harmony) are the ones upon the burden of evidence lies, not upon those who think the intellectual capacities might be as variable as any other capacity.

For those who think there are "so many factors" that might explain away different Levels of performance, those are the one to come up With evidence that those factors are..significant enough.

Furthermore:
If we think biology here, on where to expect "maximal learning potential" relative to outset, we should expect maximal learning potential to appear on those capacities that might often come in handy to Train in order to survive, whereas those capacities that hardly contributes to survival/gene propagation will remain rather more static flukes of personalities.

Since aptitude for algebra is hardly helpful in the adaption game, there is no particular reason why we should have a greater relative learning potential in that than in, for example, the learning potential to develop olfactory skills (which might well be of very good use for purposes of adaptation).

If you rip some muscle, damage some limb, or otherwise cause severe damage to something that impacts your dexterity or mobility (something not in the brain), will the body adapt and restore that function for you? I'm pretty sure there are cases where people lose their sight, but recover because the brain "rewires". Nobody is denying that there is variability in the biology. The actual question is whether or not minor variability in the brain, variability that does not dramatically impair the individual, can prohibit the learning of certain ideas.

There is nothing set in stone about where the burden lies. It is each our own responsibility to reconcile our own conflicting ideas. So are you going to say that the brain does not exhibit any sort of robustness to variability or damage?

Perhaps you should read what I actually write, rather than put words into my postings that never were there to begin with?

I'm not putting any words in your postings. I'm asking you a question. You can answer it, ignore it, or tell me that I misinterpreted what you said. You seem to have thought that the best course of action was to accuse me of purposely misrepresenting you. Thanks for that.

I'm saying intellectual matters differ from something like swiftness. Swiftness can be attributed to the muscle, which is not as adaptable as the brain. I gave you an example. Is that something you would consider deep or mysterious? I don't know. Who carries the burden to defend themselves now? I say, if you recognize this property of the brain, then you should give a defense because you seem to have a completely one sided belief.

Why do you even think, for starters, that not understanding differential equations, for example, is in any way some sort of brain damage analogous to ripped muscles?

huh? I made an analogy between loss of sight and impairment of mobility. The only point I'm making is that one can adapt(or: recover its own functionality), and the other cannot (to my best knowledge).

Recovery is a form of adaptation and I have no idea whether or not the adaptation can manifest itself differently (through learning perhaps). Do you?

Or is it unreasonable to think that the brain adapts in any other way?

I don't necessarily see people denying the existence of variation. Rather I see some people claiming that finishing a BS/MS or equivalent in a STEM field is beyond the capability of certain people simply due some innate lack of capability.

Others, in my view, are on here trying to espouse the point that people don't finish BS/MS degrees in the STEM fields or get bad grades in STEM related exams due to a multitude of factors having nothing to do with innate capabilities.

I think doing completely revolutionary work like IE: GR and what not, should be put aside because those situations are extraordinarily complex.

And some fail to become a pop star, because they simply haven't got what it takes to beguile a big enough crowd that the singer is a god or a godess. Actually, that "some" might be replaced With, let's say, 99.9% of those trying to charm the world to their tunes.
However, everybody can get a little bit more charming. Even I.:smile:
 
  • #45
Are you equating being a world famous pop star to finishing a BS/MS degree in a STEM field?

Don't you think you're bringing up the extreme again? Becoming a pop star is more like being the next Einstein.

I think a more apt comparison would be the guy who is a good musician who plays gigs on the weekends and a competent Engineer who can design a building or bridge which is safe and secure.

EDIT: I'm trying to speak about moderately attainable goals here. Which is why I'd like to get away from the whole, anyone can be the next Feynman, business.

To bring another analogy into the mix, do you think that the average joe, with enough motivation and training, can't run a sub 9 minute mile?

No one is making the case that intellectual capabilities are outside the realms of scientific testing, but a surefire way of doing so consistently does not exist as of yet. It is the people who claim "some just can't get a BS" that have a whole lot of explaining to do. You're the ones establishing a constraint on the system. If we're going to approach this as a serious scientific problem with some modicum of intellectual honesty, you have to provide a decent phenomenological reasoning behind that constraint. Not doing so is equivalent to invoking a magical quality to be able to sit through and complete the requirements of a degree.

There's an awful lot of strawman arguments and irrational thinking in this thread. Seriously, this discussion has descended to the level of bold-face assertion internet theism vs atheism arguments. Evidence-backed statements, humility and intellectual honesty are nowhere to be found.

Nonsense.

Saying it is likely that basically the same types of constraints exist for "intellectual" capacities as for "aesthetic" capacities and "physical" capacities is the proper, rational reductionist attitude.

It is those who think intellectual capacities are somehow deeply different who have the burden of evidence upon them.

Another strawman argument.

Nobody has said limitations don't exist. But nobody has made a case as to what they are specifically, how they can be determined, and what their consequences are while still accounting for all of the "happy clappy examples" that completely negate the notions that "some people just can't, period".

You established the constraint/stated the physical law that x is never possible, then the onus is on you to explain why and support it with evidence.

Doesn't look like this thread is going to mature past bold face assertions...

I'll get back to you in a few years to see how I am getting on. If I am rocking then your argument is moot. I don't have natural math talent.

With all due respect, but I think it's pretty obvious that not everybody can get a BS. Do you think people with mental retardation (http://en.wikipedia.org/wiki/Mental_retardation) can get a BS? Some of these people can't even feed themselves or have a decent conversation. I doubt there is any kind of education that can get them to a BS.

Of course, this is just an extreme case. But intelligence is supposed to be a spectrum. Some people will be close to mental retardation and some people will be far away. So there will be some people who will never be able to complete a BS.

Do I know proper tests to distinguish who can complete a BS and who doesn't? Do I know a clear cut-off point (like if you score below 100 you can't get one)? No, and I don't think such things can ever exist.

As much as I would like to believe that getting a BS is just a lot of hard work, you can't deny that there has to be a certain aptitude for the subject.

I learned from this website that in order to discuss something about physics you need "axioms" both parties can agree on, not everything can be known / proven. I'd guess 5 - 6 billion people is a bit much for both parties to know everyone, let alone know who is "really trying" and who isn't.

So it must be just the 90% or so percent we could call the "general population". Plus it'd seem illogical to include those on the "fringes" of Entire population when the thread itself is titled There Are No Miracle People. Of course those on the lower end of the curve are miracles too, as used in this context.

maybe your hyperbole was to point this out to Lavabug."you can't deny that there has to be a certain aptitude for the subject."

I think Lavabug may have said that the burden of proof is on you. That's said, generally speaking of course intelligence and academic potential correlate far far more often than not.

Do you think there will be an empirical way of determining who can learn what? I don't think anybody really cares about it being in test (paper examination) form.

What do you mean?

No offense to you guys but I believe that if you memorized everything and also learned how to manipulate equations. You wouldn't even have to fully understand them. I seen a thread elsewhere on the internet where engineers posted about calculus and they where using it without fully understanding it. Trufax bro. http://betterexplained.com/articles/developing-your-intuition-for-math/ Calculus section.

I'd imagine there is a curriculum of stuff you got to get through. Classical, Relativity and Quantum mechanics. Your last piece is likely something that has been done before no matter I bet how obscure you'd try to be unless your doing a PHD or something probably cutting edge there. To be honest someone needs to do something radical its why I am interested in the whole shabang. This casimir experiment needs going over with a fine tooth comb. No laws of thermodynamics is going to put a nail in that coffin unless I personally skull bash over it when I know more. And before someone calls me a loon them DARPA boys are already at it only thing is they harping on about anti gravity bit of a red herring if you ask me. If it isn't then they must think they can get that stuff to move. Aether theory isn't fully dead.

I imagine creating your own equations is like dipping into the repertoire of what is already there in the context of the situation. Before that you deduce all the variables, decide what going to work then sort out your units. Plug and play baby. Well at a certain level I seen some first year questions and they where utilizing f=ma. Though even doing this wouldn't be easy but I'd agree to really shine you'd need to know what your at, so you probably need talent for that. I am making assumptions here though I could be wrong. But you'd say that anyway.

But I don't know how you can figure out if you got any until you try. Some peeps are truly gifted like that american autistic kid Jacob who is tipped for the nobel prize. Others are probably not so lucky while the rest of us are in between. Well could be some geniuses knocking around here. WannabeNewton impresses me but you'd have to be with a name like that.

There is test, as in a paper examination. Then there is test, as in a scientific experiment. It was clear he doesn't think the former is possible. Is the latter, and more general, possible?
