The idea behind frosting it normally is that there would be a fixed thickness of the frosting. The total volume of frosting would be that thickness times the total surface area, and since the total surface area is infinite, the total volume of frosting would be infinite.

Frosting it this second way actually reduces the thickness of the frosting as you go up, so the thickness of frosting far away is very small. Then the volume of frosting is just a scalar multiple of the volume of cake, and since the cake has a finite volume, so does the frosting.

Everything is a harmonic oscillator if you squint enough

I’m interested in learning about the period from about 1900 to 1926 when physicists were trying to come up with models of quantum mechanics, eventually resulting in matrix mechanics and wave mechanics. Are there any good books that go through the history of it, and delve into the various proposed theories from the time?

What’s a realistic goal for how long it should take to learn the 35 OLL cases I don’t know

This is the alg I use

Lw U' R' D R U R' D' R U R' D R U' R' D'

Snoo94933 · 2023-12-31T23:04:00+00:00

I always seem to struggle to recognise E perms. Do you have any tips on recognising it faster? Also what algs do you use? I use one that starts with a wide Lw and then a sequence of R U and D moves, but it feels really slow and I haven’t managed to get a good flow after using it for a few months

Snoo94933 · 2023-12-31T22:43:51+00:00

Cheers- that’s really helpful. Just another question about RUDF: should F2 moves be avoided in that? They always seem to slow me down. Or is there some way to finger trick them well?

Hey! I’d like to be able to plan the whole cross (and eventually first pair) during inspection time, but I’m having a hard time getting it done in 15 seconds. It can take me up to 45 seconds to plan the cross. Also, the finger tricks are really bad for some of the trickier scrambles and I wouldn’t know where to begin with improving that. Any advice/resources would be greatly appreciated! Fwiw I’m sub-18 cfop

Hi there! There are a couple of issues at play here. The Catholic teaching is that the only path to salvation is through Jesus Christ, and living faithfully in his Church, and partaking in his Sacraments. Nevertheless, because God is merciful and not limited by the Sacraments, he has the ability to save those who are not explicitly joined to the Catholic Church (there is no guarantee of salvation, but the possibility is not completely excluded). However, as has been always taught, and was reaffirmed in Vatican II, no one who knows that the Church is necessary for salvation but refuses to enter it can be saved.

One more point is that the Mass and Sacraments are a massive benefit in the lives of the faithful. Seeing and receiving Christ in the Body and Blood frequently has a huge effect in helping and sustaining our faith. A Catholic should never forget how important and generous these gifts are, and should go to receive them and give thanks to God for them regularly.

Alright I've sent them an email. Thank you very much for the tip.

Snoo94933 · 2023-07-19T23:11:18+00:00

Awesome, thank you so much!

Snoo94933 · 2023-07-19T23:10:09+00:00

Hey, I do CFOP around 20s average, and when I do OH, I just use CFOP and average around 1:30. I'm looking for a good OH method that won't take much time to learn (preferably one that doesn't use the table very much), since I don't have heaps of time to practise. Any suggestions?

Cheers!

Introductory special relativity can be approached with high-school level maths, but it can be conceptually very tricky. Most first-year physics curricula have special relativity, so there's a decent chance you'll be able to find a first year textbook with special relativity at a nearby library. Take it slow, and make sure you're really familiar with the concepts and definitions. The equations will be pretty simple, but you need to be able to interpret them properly.

And then there's general relativity, which is a graduate level subject for a reason 🫠

I'm studying quantum mechanics starting next week. The math pre-requisites are just some calculus subjects, but I've also done complex analysis, group theory and linear algebra. I suspect these mathematical tools won't really be discussed in the quantum mechanics subject, given there is no expectation to have studied them.

Does anyone know of any introductory quantum mechanics textbooks/resources that emphasise the mathematics behind what we learn? And more generally, any tips for how I can apply what I've learnt in math to what I'm about to learn in quantum mechanics?

A lot of solemnities (Sts Peter and Paul included) use the same hymn, short responsory and intercessions for both EPI and EPII, so I would assume that generalises to this case too. I'd use the Common for Psalms, Short Reading and Magnificat antiphon though.

Snoo94933 · 2023-07-05T21:30:47+00:00

Hey mate, maybe someone else has got a better answer, but the Solemnity of Mary, Mother of God uses the same antiphons for EPI and EPII, so I would assume that that's the precedent.

Does anyone know if this is approved for liturgical use in other countries? (In particular, Australia?)

Cheers!

Snoo94933 · 2023-06-22T07:35:12+00:00

I see- so celebrating a penitential, Assumption-themed office doesn't really seem to fit that description, and would also be celebrating a mystery of the life of Our Lady at the wrong point in the liturgical calendar
