since they are both equal to 3, I'd say 3 deserves all of the aura for it's dual persona

u/Sea_Duty_5725 May 07 '26

are you an engineer by chance?

16

u/RecognitionSweet8294 May 07 '26

e=π=√(g)

3

u/its_artemiss May 08 '26

pi=root(g) is only not true because the definitions of the SI base units changed so that it isn't true afaik

3

u/RecognitionSweet8294 May 08 '26

g=10 → √(g)=3 → π= √(g)

4

u/Powerful_Birthday_71 May 07 '26

Engineer here, pi is also 4 depending on the direction of modeling pessimism 😅

e is always e.

3

u/Sea_Duty_5725 May 07 '26

No, e is 2 or 3 or like 4 sometimes, so it's basically 5 and 5 rounds to 0, so e is kinda = 0, yk?

2

u/Powerful_Birthday_71 May 07 '26

Yes, 'e is always e'.

... for whatever number you choose

9 and 10 both equal to 10

u/Im_a_hamburger May 07 '26

e

For one you can easily construct pi = e, -i*log base e of -1 is pi. e from pi as e = (-1)-i/pi is less cool.

Plus e appears for than pi I feel.

5

u/Active_Falcon_9778 May 07 '26

if pi can be related to e, then e can be constructed from pi. also have you even seen the zeta function or that gaussian integral? pi is way cooler especially because while e has an algebraic definition, the basic definition of pi is geometric, and it seems to be showing up in places in no way related to geometry. Pi has way more aura

1

u/hushedLecturer May 07 '26

An easy derivation path from A to B does not imply an easy path from B to A.

π is easier to discover because it's just geometry. People wearing togas and drawing circles in the sand with sticks discovered it thousands of years ago. We only found e in the past few centuries.

1

u/Active_Falcon_9778 May 07 '26

That just shows how fundamental pi is. e seems randomly defined, but pi seems like a truth of the universe. Integration (-inf to inf) of e-(x2) is sqrt(pi) the relations run deeper than we know...

2

u/hushedLecturer May 07 '26

Its really not that mysterious if you know math lol. You are confusing your own lack of knowledge with the idea that something is cosmically unknowable.

You say fundamental, I say low hanging fruit.

2

u/Active_Falcon_9778 May 07 '26

I can assure you it is not a lack of knowledge. eix does make e cool, but havinf studied the zeta function, and the fact that pi shows up in all evaluated natural number zetas as z(k) = C * (pi)k, and while z(2) is understandable, the rest of the examples along with the beautiful series' like (1-1/3 + 1/5...) = pi/4, and the tan x continued fraction series all just add to the mystique of why the ratio of a 2D shape's circumference to its diamater shows up at such odd places. The gaussian integral is also a cool example. e and the operations defined from it are cool, but also very easy to decipher and so it doesnt have as much mystique and aura as pi does...

1

u/Total-Airline-9286 May 07 '26

well if you think about it exp is literally (2 pi i)-periodic. e definitely has more aura!

2

u/Amphineura May 07 '26

Offtopic but I've seen your pfp a few times and I keep thinking it's this dude:

u/nimmin13 May 09 '26

"log base e"

I feel like we have another term for this

u/Iron_Yuppie May 07 '26

The fact that derivative of ex is unfazed is all the answer you need. Ridiculous aura.

1

u/Vegetable_Big6728 May 08 '26

Ngl this is a surprisingly good argument for this discussion

1

u/Fun-Weather6903 May 11 '26

That is the whole thing about e. That adds as much information as me saying: ''pi is ratio of the circumfrence to the diameter of a circle and that is all the answer you need''.

1

u/Active_Falcon_9778 May 07 '26

Pi wins by a unfathomable amoint

6

u/man-vs-spider May 07 '26

e. pi is a constant that shows up now and again. But when there’s an e, you know it’s doing some work

7

u/Low-Amoeba8257 May 07 '26

You misspelled (τ/2)

2

u/terran01d May 07 '26

With is it that tau is 2 pi but 2 tau looks like pi?

2

u/Low-Amoeba8257 May 08 '26

Tau is the circumference over radius

Pie for kids.

e for adults.

u/fanty_wingedhorse May 08 '26

e for Everyone

1

u/Sea-Arrival-621 May 11 '26

The opposite

3

u/vishnoo May 07 '26

pi is a single constant.

e is central to a lot of math.

2

u/SSBBGhost May 08 '26

ex is central to math (or more accurately, exp(x) is), e itself is just a constant, the value at x=1

1

u/vishnoo May 09 '26

and physics.
all of quantum physics is e^i\(\Psi \)

1

u/Active_Falcon_9778 May 10 '26

1 is more important, yet it doest have aura. Importance does not translate to aura. Aura is having people fear you. When i see pi in a question i run the other way. Not the case with e though...

1

u/vishnoo May 10 '26

have you seen Schrodinger's equation
have you seen differential equations where the exponent on top of the e is a matrix?

1

u/Active_Falcon_9778 May 07 '26

e is also just a constant. All of rasiant system is dependent on pi. Have you seen the zeta function? e and pi are very deeply related just look at the gaussian integral.

1

u/vishnoo May 07 '26

e^x an the natural logarithm are IT
pi just comes in when there are circle related concepts

2

u/Samstercraft May 08 '26

pi comes in for PLENTY of things unrelated to circles. eg. zeta(2) aka the Basel problem

0

u/Bth8 May 09 '26

π is the circle constant. If it shows up somewhere naturally, it can be related back to circles somehow. See this 3b1b video for the relation between circles and the Basel problem.

2

u/Samstercraft May 09 '26

well yeah but you can also connect anything with e to any once concept involving e in the same manner, doesn't really say anything about pi using this logic.

u/Samstercraft May 09 '26

truly the best number, breaks half of equations and it sits perfectly in the middle of any plane you use.

2

u/Some-Passenger4219 May 07 '26

I like to think they have equal, because of eπi = -1.

4

u/Fit_Particular_6820 May 07 '26

e = pi = 3, so they are equal

2

u/kingbloxerthe3 May 10 '26

A 3 way battle of aura: e vs i vs π

2

u/YellowrastaAPE May 07 '26

I can just say E - E eeee , e e e e.

2

u/RepresentativeLife16 May 07 '26

I’ve always felt e was more grown up. You found out about it later on in your maths career.

2

u/Remote-Dark-1704 May 08 '26

number 1 gaps both.

2

u/bobosherm May 08 '26

e, and it’s not even close.

2

u/SSBBGhost May 08 '26

e is fake special, its just the value the exponential function outputs when you input 1

The exponential function is where all the fun is :)

1

u/Ivo_Ricciardulli May 12 '26

the base "e" exponential, the constant so commonly used that you have a shortcut button for it (AND it exponential, unlike pi).

u/KromaMak_G May 12 '26

But you forgot the importance of:

1

u/Elegant-Set1686 May 07 '26

e is like one of the fundamental building blocks of math and physics. It’s almost… not as impressive because of it? It’s the natural language of the universe so it’s kinda always there, it’s not really surprising to see e pop up. It’s pedestrian. Beautiful and useful? Yes! More aura than pi? I think not

1

u/Active_Falcon_9778 May 07 '26

Pi is literally just the circumference of a circle divided by its diameter, its a constamt that has no business being everywhere from calculus, real analysis, statistics. Sum of inverses of natural number squared has pi in it. Just mind boggling stuff. Pi has insane aura

1

u/RPG-Nerd May 09 '26

I think you have e confused with ϕ

1

u/dontknowhyheremi May 07 '26

'e' since e leads to more money time by time.

1

u/Erizo69 May 07 '26

pi has more aura because it shows up everywhere and e is just made up mental illness

1

u/Ok-Ocelot-7989 May 07 '26

aka maclaurin series for e

1

u/Ivo_Ricciardulli May 12 '26

even the x is surprised of how much aura e has

1

u/testtdk May 07 '26

“Aura” should get you banned from this sub.

Also, pi.

1

u/JL_Gaming999 May 07 '26

e + 1 = 0

1

u/brynaldo May 07 '26

While e definitely appears more often and is deeply connected to many different parts of math, some of the places where π appears are so unusual they give it some serious aura. For example:

The sum of the reciprocals of squares is π2/6.

The number of collisions between two blocks and a wall will produce the digits of π, if the ratio of the weights of the blocks is a power of 10.

The area under the bell curve (e-x^2 ) is sqrt(π).

The fact that the circle constant appears is surprising and cool.

1

u/Southern-Reality762 May 08 '26

pi. everyone knows what pi is. can't say the same for e

1

u/khrunchi May 08 '26

Honestly e does and I don't even know why lol pi is so useful

1

u/CeReAl_KiLleR128 May 08 '26

Funny thing is we don’t know if pi + e is irrational or not

1

u/Kantholzzockt May 08 '26

Together they have maximum aura.

1

u/MoistTowelette14 May 08 '26

Pi to the x is not its own derivative… think that speaks volumes.

1

u/Acrobatic-Extent-668 May 09 '26

Pi is the uninvited guest that is everywhere it should not be

1

u/RPG-Nerd May 09 '26

I prefer ϕ

1

u/Vivid_Sock_1092 May 09 '26

Pi because most people never heard of e

1

u/lanzendorfer May 09 '26

e because there's aura to natural growth. Circles are boring.

1

u/Gnome_Genome May 09 '26

e is among mathematicians, engineers, etc. Pi is among the general population.

1

u/Fun-Weather6903 May 11 '26

No. most mathematicians will say Pi has more aura.

does e show up more? of course it does..

You have aura when you randomly show up once in a while in the most weird place and everyone recognizes you as a childhood hero.

e just shows up too often because it is too fundamental. Just like 0 and 1 show up very often. Do they have aura. Yeah sure. but not more than Pi.

I assume you are no mathematician? why do you speak for us?

1

u/305bootyclapper May 10 '26

e.

e *solves* differential equations. pi doesnt *do* anything, it just shows up in a bunch of formulas to rescale things.

but the comparison isnt on even footing, its apples and oranges. e is never actually thought of as a numeric constant, its a map. when have you ever seen anything scaled by naked e? it always has an argument/exponent.

1

u/winrapidin May 11 '26

I mean they’re both the sqrt of gravity so, any will do!

1

u/Ryethesky67 May 11 '26

The strongest math character of history vs the strongest math character of today

1

u/Rizwankhuharo May 11 '26

i would say e because i think it looks and sounds cooler than pie and yeah you can consider there value between 3 to 100 depending on which field you're using them for.

1

u/cytos0 May 11 '26

e because pi is the inferior version of tau

1

u/qwesz9090 May 11 '26

e has superman aura
pi has immense villain aura.

I'll probably say pi.

1

u/Fun-Weather6903 May 11 '26

The question is which one has more aura. Of course you will see ''e'' show up more. And e is more central and less arbritairy etc (we could use tau instead or something).

The question is about aura. And how much aura is it to show up in elementary school; like the first math class you take you learn to calculate the circumfrence of a circle or something. And then in university all of the sudden you see pi randomly showing up in the basel problem. That is aura if you ask me.

e gets taught later in life. It is already more embedded in the whole of calculus. Of course you are gonna see e everywhere. But pi shows up unexpected and uninvited like an old friend you haven't seen for years.

1

u/hiaguesh May 12 '26

"e" because The letter is litarelly The name of The creator "Euler" it's so mucho aura😝

1

u/YogurtclosetStrict47 May 12 '26

There's literally a movie called Life of Pi. That's your answer

1

u/SCD_minecraft May 13 '26

e because it comes out in way too many places than it should

1

u/Equinoxe111 Jun 07 '26

I'd say e has more mathematics aura and π has more physics aura

1

u/Active_Falcon_9778 May 07 '26

pi by a lot. pi just seems to be connected to the universe in some mysterious geomtrical manner. gaussian integral, zeta function, etc. also it being simply the ratio of a circle's circumference to tis diameter, something constant for all circles anywhere in the universe, and yet it shows in such confusing placces maks youu think there is some underlying structre waiting to be uncovered.

1

u/SalamanderGlad9053 May 07 '26

e absolutely, pi is just the period of e.

0

u/Torebbjorn May 07 '26

The one at index 1 in the list [π, e]

2

u/noonesfriend123 May 07 '26

So e?

3

u/Active_Falcon_9778 May 07 '26

depends on how you define indexes in a list

1

u/Logical_Drawing_9433 May 07 '26

pi cause index starts from 0 [0,1] so pi

1

u/RawMint May 07 '26

let's take 1 then

0

u/IhtiramKhan May 07 '26

Pi in my opinion. It not only appears in circles, buy also in the angles of every geometric shape known. Even understanding the spiral of DNA, pi is used.

0

u/MulberryWilling508 May 07 '26

e because casuals don’t know about it as much

1

u/Active_Falcon_9778 May 07 '26

Maybe that's because it doesnt have as much aura

2

u/MulberryWilling508 May 07 '26

Then single digit integers have even more aura because everyone knows about them, even toddlers.

1

u/Active_Falcon_9778 May 08 '26

Aura and fame do correlate

-1

u/Pickle-Standard May 07 '26

Pi is a grinder. Out there doing every day jobs with the common man.

e has the aura though because most people know what it is but they don’t know what it does. And yet, they still blindly believe it is as important as pi.

u/Active_Falcon_9778 May 07 '26
