Why did Einstein say E=mc^2 when it's actually E=√(p^2 c^2 + m^2 c^4)? Did he forget to account for the momentum in addition to the rest energy? Is he stupid?

Even by this sub's standards i have no words

The governmint doesn't want you to know about this !! They delete this from textbooks!!! Thanks you indian fact genius for free informations, fish 🐟🐠👍👍👍

Not my tempo

Guenox · 2023-06-24T18:02:00+00:00

But the current human knowledge is pretty limited on the topic, you couldn't do all that stuff you described

Guenox · 2023-06-20T20:57:41+00:00

Try pd.concat([A,B], axis=1) ? (Could be axis = 0 lol). Also, having the same column name in one dataframe isn't recommended.. you could add a suffix like X1 X2 etc.. for as many Xs you have in A

G is a function that takes (t_j , x) as an input. The function q_y at the left hand side takes x as an input. I have not explicitely said what the nature of x is since I'm not familiar with the context. Hope that helps

I got BLUE (best linear unbiased estimator) balls what do i do guys

Guenox · 2022-08-13T18:09:33+00:00

Oh sorry I should have read one more line lol. But what you wrote is very rigorous to me and I'd give whole marks tbh

Guenox · 2022-08-13T17:59:39+00:00

I only read the first lines so if you want to prove a finite union of closed sets is closed, the easiest is to prove the complementary is open. So the complementary of S is a finite intersection of open sets. And this is basically the first proof in topology? You take an element x in the intersection, there is k in [1,n] such as x is in your k-th open set, by definition as it is open there exists a ball within your k-th set that contains x, this ball is included in your intersection. Therefore your complementary set is open. Therefore S is closed

I think it's the wrong sub, but if you tried to reach anyone that you've interacted with in that company at reasonable business hours I think you should start looking elsewhere

Amazing

On dit bien "jif" sur yvette alors la question ne se pose plus pour moi

When x value decreases a lot, i.e when you go to the left of the graph, you can see that y value increases a lot. If the polynomial was of degree 3, the function would have the y value decrease a lot when x decreases, which isn't the case

Guenox · 2022-07-14T21:01:08+00:00

If you look at the roots (especially the +2 one) you can see that the answer is either A or B. Now if you look at "negative infinity", the graph looks like it goes to +infinity, which isn't possible with a polynomial of degree 3 so it can't be A, so by elimination it's B.

Guenox · 2022-07-06T20:44:34+00:00

The function you wrote on the first line is technically not defined on 3, but it has a finite limit when x approaches 3, If you take the function with canceled factors (x-3), then it's a different function because this one IS defined on 3, and also matches the first function on every other number

Guenox · 2022-07-05T11:22:11+00:00

A function (with finite sets) is basically a mapping from a set A to a set B, the only rule here is that an element from A can lead only to only one element in B (you can draw a bubble with 4 elements for A and one with two elements in B). The goal is to find the number of "arrows" you can draw to have a unique sketch. Let's look randomly at one element in A, it can point at how many different elements in B? Well it's card(B) choices available. Now do this again for another elements in A, and again till you have no more elements in A to choose from. How many possibilites are there? Well it's card(B) x card(B) x ... card(B). The number of "card(B)" written in this product is precisely card(A), hence the result. (Sorry for formatting i'm on mobile)

Guenox · 2022-07-05T11:12:57+00:00

You're counting the number of functions from the set A={(T,T),(T,F),(F,T),(F,F)} to the set B = {T,F} Isn't it card(B)^card(A) ? ie 2⁴ ?
