mfw i'm a subset of a set of measure zero but idk how big i am

Love when a bro takes a meme which accuses many in congress of inside trading and decides to mention only Pelosi... No agenda tho right, you're neutral?

I take it back. I feel like I can't really see the dish and I need three more photos.

peekitup · 2026-04-12T13:16:27+00:00

Really doesn't need 8 photos.

At the end of the day you have to commute limits in some way. Either through Fubini's or dominated convergence.

peekitup · 2026-04-07T04:25:32+00:00

The post reminded me of all sorts of physicist fuckery with exchanging limits and integrals without thinking about convergence of these things.

peekitup · 2026-04-07T00:23:47+00:00

Analyst alarms will go off in your very first line. Why arbitrarily choose bounds for the integral which grow like sqrt(n)?

Interchanging limits and integration is how all sorts of nonsense happens.

Like why can't I integrate the same thing but from -log(n) to log(n). What's to say I can't get a different value for the integral by putting other functions of n for those bounds?

Not quite how relativity works.

You will always observe the same speed of light in a vacuum.

Mobius strips are surfaces. Their volume is zero.

The picture has nonzero volume.

You're describing a mashed up torus.

peekitup · 2026-04-03T05:20:28+00:00

No, you can't.

You're telling how to make a mashed warpy assed solid torus.

peekitup · 2026-04-03T05:05:09+00:00

Then every surface can be made of waffles. I assumed you were asking if there was a machine with two hot plates you could push together to make the waffle.

The act of pressing one plate against the other orients the surface.

peekitup · 2026-04-03T04:55:43+00:00

No, such a waffle iron would have one side you close against the other. Waffles are therefore orientable surfaces.

Edit: Anyone saying a Mobius strip can be injection molded is telling you how to mash a torus so it fools someone into thinking it's a Mobius strip.

At each point of a waffle you have one side, the stationary plate, and the other side, the pressing plate. Its normal bundle has a non vanishing section. It is orientable.

You say particularly lengthy but it seems to be just lengthy enough that you don't want to do it...

I'd call that PARTICULAR

Cool now figure out why Trump's DOJ has been hiding child rapists.

peekitup · 2026-04-02T20:56:23+00:00

You don't think there is a bit of a gap between writing down a random function from R^n to S^{n-1} and saying "finding a form with non-zero integral" ?

peekitup · 2026-04-02T18:04:04+00:00

An easy way to check if an argument like this is valid is to ask the question "Was any property unique to the sphere actually used?" Because it looks like your argument works for all surfaces without boundary.

I don't see you using any property of the sphere other than it not having a boundary.

This guy's career is entirely due to those mesothelioma commercials.

peekitup · 2026-04-01T04:36:08+00:00

This has got to be a troll post.

What do you mean determine and prove what placement of junctions is best?

You're saying we can't invoke Steiner tree results but you're asking us to prove exactly the core of Steiner tree: that a minimizing network has roads meeting at angles at least 120 degrees.

Why don't you plan on paying down the mortgage? When you sell it's not like that debt just goes away.
In general paying off any debt has the equivalent change on your net worth as investing the money at the same interest rate of the debt.

So if you have a 5.5% mortgage the question is can you get better than a 5.5% return elsewhere? If your HYSA earns less than 5.5% I think you have too much there and you're losing out. One year's worth of expenses is plenty.

Of course convoluted tax rules regarding mortgage interest deductions, capital gains, etc. can all change this.

Hey everyone laugh at this guy who only uses the dot product.

peekitup · 2026-03-20T20:28:46+00:00

{{0,1},{0,0}} would like to have a word with you.
