#

this is legit unwatchable, how do people live with themselved presenting slides word for word

#

like 98+% of it is literally word for word bleak

#

the average freshman is better than this

river moon
#

wdym it's not word for wordhmmCat

fervent flame
#

it basically is

#

every thing thats written aside from code gets repeated word for word

river moon
#

depends on where you look

#

at times it could be that half of what he says isn't on the slide

#

you're overestimating what average freshman presentation looks like

neat lintel
#

Great video

neat lintel
#

any presentation that uses slides is probably shit, and 100% certainly shit it it lasts more than 20 minutes

plain owl
#

that's a very extreme take

vast surge
#

Also just an objectively bad take

vivid halo
#

chalk talks are almost always better than slide talks

#

although I've seen some really good slide talks that would be kind of disasters if they were chalk talks

#

also most slide talks are only bad because most talks in general are kinda bad tbh

#

most people just do not give good talks

cinder zephyr
#

Chalk Talks are better than slide talks IMO because of a few factors

  • Most slide talks don't actually need the slides to present material that would be hard to write / draw
  • Chalk Talks have natural pauses and such due to having to actually write
  • Multiple boards visible at once makes the talk seem more seamless
#

really the important part is the first one

vivid halo
#

yeah definitely

cinder zephyr
#

if you're presenting material that needs precise diagrams (think combo usually)

#

then use slides

vivid halo
#

the main cases I'm thinking of are talks where there are diagrams that would be absolutely horrible to draw on the board but are like, the main point of the talk

cinder zephyr
#

yea

#

although my math club, I have everyone use slides for the most part

vivid halo
#

even in those cases it's sometimes better to like, do a hybrid between chalk and slides if the room allows for it

cinder zephyr
#

because I think giving an ok slide talk is easier than an ok board talk

vivid halo
#

some rooms are large enough where you can project slides above the board and then yeah that's great

#

if the screen blocks the board then yeah that's hard to do

cinder zephyr
#

like I'm not writing that out by hand

vivid halo
#

I've seen some knot theory talks where it would be absolutely awful to try to draw all the diagrams on the board

cinder zephyr
#

I will say the biggest issue with slide talks is that its easy to write too much

vivid halo
#

slides make more sense for those

#

yeah

cinder zephyr
#

and so you end up with people reading off the slides

#

where for board talks people realize you can't write that much

vivid halo
#

slides can definitely be done well if you are aware of these issues

#

the other thing I've seen done really well is like "slides" where you leave a bunch of empty space and then actually write stuff on them with a tablet or whatever

#

but then have certain equations already there that would be too annoying to write out by hand

cinder zephyr
#

yea I've seen this done alot

#

that's an underrated option

#

my algos prof did that, it was great

vivid halo
#

yeah I really like this option

cinder zephyr
#

I also saw a great piece of advice which works well for more complicated stuff

#

where you just lie

#

in that say a proof is very complicated

#

but that complicated part is for like 10% of cases that you'd only come up with when doing the proof

#

just present the simple proof of the 90%

vivid halo
#

best talk I've ever given I ended it early and then it had 40 minutes of discussion at the end with profs in the audience

cinder zephyr
#

chances are few if any will notice

#

and if anyone does notice you can mention that lie verbally

#

but it ends up being a smoother talk

#

Hm I'm trying to think what the best talk I gave was

cinder zephyr
#

from last spring

bronze wedge
cinder zephyr
#

Well there is a difference between bad talk and not knowing stuff

#

very similar to the idea of a good-researcher-but-bad-prof

velvet dagger
#

Like oh hour long talk? More like 20 minute talk

#

Which would be wild

cinder zephyr
#

that's how I read it too

#

and only now do I realize that's not what was meant

wooden flax

#

I feel like I gave a good ten-minute talk recently; I stayed pretty surface-level, but it had good flow, motivation, and energy

#

The audience seemed to like it at least

cinder zephyr
#

I want to put together a 10-15 minute talk

#

for a small seminar at my school

#

gotta think of a topic (should be computational in nature)

I replied "We don't have those LMAO" to a question about my assigned academic advisor.
Does anyone in undergrad actually have those?
I asked the people at my college and they all said no

do you not sit down/discuss your coursework plans with anyone?

no

#

Who here has learnt number theory?
How many times in a day do you use what you learnt from it?

#

I started learning it for competitive programming. I have to say I've used it about zero times

zealous garden
#

I actually have one question I want answered that I have yet to find an answer to with my limited looking

#

I wanna know where the octonion GA is hiding

#

Of course the octonions themselves can't be in a GA, because they're nonassociative

#

But if I'm not mistaken their automorphism group is a lie group

#

Which makes it isomorphic to a subgroup of the spin group of some family of GAs

#

Particularly, there's some smallest GA with G2 in/as its spin group

#

I want to know what it is

lime vigil

gritty totem
#

I am really starting to think that GA is a cult

alpine copper
#

i have some doubts about GA totally encompassing exterior calculus

zealous garden
#

Just look at the respective tensor algebra constructions

#

T(v)/<v^2> is clearly a special case of T(v)/<v^2-B(v,v)>

alpine copper
# zealous garden What is there to doubt

the existence of a clifford bundle on any smooth manifold which requires some representation of the spin group which requires spin structure. While exterior calculus is generated by exterior powers of the cotangent bundle which is always possible

zealous garden
#

I believe they're also naturally isomorphic if you do it right (symmetric bilinear forms instead of quadratic forms)

#

spin structure

#

I don't know that word, you just need a metric to have a tangent algebra at each point.

#

And the zero metric works

#

I can also use a vectorspace and it's dual space to make the mother algebra

alpine copper
#

well Im referring to how GA works on manifolds

zealous garden
#

So the tangent and cotangent bundle combine to give me access to all possible GAs at every point

#

What is the obstacle, what is restrictive about spin structure

alpine copper
#

it obstructs a consistent choice of spin group representative at every point that passes down to the special orthogonal group (which is determined by your metric)

#

and iirc, GA algebra always admits a faithful rep of the spin group

zealous garden
#

Every pseudo riemannian manifold admits a clifford bundle

#

A natural one

zealous garden
visual breach
#

Just faithful representation of spin group?

zealous garden
#

If you mean the ability to exponentiate bivectors to get automorphisms that are continuously connected to 1, yes

What would be the correct way to study group theory?

There are standard ways. I don't know if there's a "correct way".

You didn't end up doing group theory...

You switched to number theory instead

Group theory is overrated

bronze pelican
#

Ur just unenlightened

charred burrow
#

I am going to study Galois theory soon

#

Should I be concerned

bronze pelican
#

In my experience, Galois theory took 2 passes to fully appreciate. First you learn I learned it abstractly for fields (Dummit and Foote). Then i put it in context with number fields (Marcus). I actually only 'got' Galois theory once I saw it being used in the study of number fields in algebraic number theory

charred burrow

#

Unfamiliar with that book

I taught from DF last semester and it kinda went badly

Well I still got a month, I should review some rings and fields in that time.

How are they expected to do Galois theory if ring theory isn't a prereq?

@bronze pelican

Are you expected to give a crash course in it?

but yeah there's no definitive way

prisma plinth
#

I am interested in Galois theory because I want to figure out what about finitivity forces F^Stab(K) = K to hold for intermediate fields

I think it’s due to Artin’s Lemma. But a lot of it uses vector space magic

my experience with my first group theory class was mostly good...

but fuck group actions, I hated proving stuff with those, it all feels like pulling a rabbit out of a hat by doing some weird obscure action

group actions are group theory

but it's annoying when you need to use them

a lot of that stuff was still cool though

I see what Namington is saying though, group theory is mostly just cleverly applied group actions

#

Like you get a lot of it that way

stone ferry
#

you do, and I don't like it

#

because the proofs are hard to see the motivation behind

mild nebula

Fair! Makes sense actually

I have to assume they just tried a lot of actions to see what they could get

$b_1 + (b_2 + b_3) + (b_4 + \dots + b_9) + \dots \geq b_1 + 2 b_3 + 6 b_9 + \dots = (b_1 + 2 \sum_{i = 0}^{\infty} 3^i b_{3^i})/3$ and $(b_1 + b_2) + (b_3 + \dots + b_8) + \dots \leq 2 b_1 + 6 b_3 + \dots = 2 \sum_{i = 0}^{\infty} 3^i b_{3^i}$.

So the convergence is equivalent; if you're looking at the explicit bounds relating the values of the sums, that might be a bit more complicated.

Assuming the terms of the series satisfy $b_1 \geq b_2 \geq b_3 \geq \dots \geq 0$.

why would you have to stop

hobbies exist

even if you spend the next 5 (or 10) years doing math full time, it is very unlikely that you will get a long-term job doing mathematics

my suggestion is be open minded and find intrinsic motivation in the things you do

aside from x, you also need to provide values of y(0), y'(0), y''(0), y'''(0) and y''''(0)

which I doubt wolfram alpha can do on it's own

well if it can come at y'''''(x), why wouldnt it be able to find the loewr derivatives?

You could argue that existence of a global market would increase demand to drastic levels in a capitalistic society

Think about if you are a company and you have a demographic of 100 people to sell to and manage their needs

Because of this you hire 10 employees

even tho they participate in globalization

Yeah the reason they are poor is because of globalization and industrialization

Also social policy lol

But they usually give easy questions

seriously, cuz i see lots of people claiming that the Gaokao is the hardest exam, but there are countries whose students litterally learn calculus, series, complex numbers, algebraic structures and much more just in high school.

which countries do that?

my guess is india

Wdym 'pretty average'

abstract mirage

I really don't think the Gaokao is harder

#

that's what i mean

visual breach
#

Yeah, I mean I'd not say this one is harder, either

#

Each of them has its own difficulty, in different ways

#

Also the topics dealt with in the exam are not difficult, most high schools would teach that I think.

abstract mirage
visual breach
#

I mean, the content as well - it is not really deep, the level is appropriate for HS level.

abstract mirage
#

I gotta disagree man!

visual breach
#

What

#

How much did you look into education systems of other countries?

abstract mirage
#

Enough to claim that this is one of the hardest.

visual breach
#

Based on what I have seen in Gaokao, I think this one is not particularly harder than that

#

Though I would not say Gaokao is harder, either.

#

I also do not think 'One of the hardest' means it is not appropriate.

abstract mirage
#

I have seen some Gaokao tests, and I can tell, it's really about how deep you know about each of the topics you're dealing with. But this one is really something different than that, if you look into the exam carefully you'll see that each question has its own way to be dealt with, and that's what I think is hard about this exam. Definitely not as standard as you thought.

visual breach
#

What do you mean by 'each question has its own way to be dealt with'

#

An exercise about limit with lots of hints

So I’m in Grade 9 Pre-IB, and I just got my grade 10 course selection and I was just wondering what the “m” means at the end? I got two sheets, one being for academic and one being for IB, and math for academic is mpm2d, while on the IB sheet, it says mpm2dm. Will I be in a different class from?

Whereas in the US since the masters gets folded in there's a lot of flexibility of topic

the formal process is kind of a sham tho

Those were my programming exams, the "guess the output" questions were the worst.

It got even worse with data structures, man every damn pen and paper programming question required so much deliberation, you needed to think up a plan of how you gonna procced because if you didn't you would be screwed when you inevitably have to deal with some complications with the solution.

And now you had to deal with all possible edge cases, those were troublesome to deal with.

and the "guess the output" question now where on overdrive, they where incomprehensible, man i freaking hated those the most, you needed to turn into a human debugger capable of reading the most BS code imaginable.
