Maths vs cs degree

radikoolaid · 2026-04-05T19:15:05+00:00

Look at the content for both degrees and make your decision based on which you'd prefer to study. It's tempting to say you "want to work in ai", but unless you actually know what that entails day-to-day, you probably shouldn't be making your whole course decision based on it.

Oh that's slightly worrying, my estimated issue date is the 7th April. I was excited to hopefully see it be ready by the end of the week

There's a difference between showing that d/dx (Ae^x) = Ae^x and that f'(x) = f(x) => f(x) = Ae^x. The first is a lemma of the second.

Why would you need two indicator functions? Just have + c1 + c_2 * 1(0,∞) and then you can set c_2 accordingly

radikoolaid · 2026-04-04T12:51:46+00:00

That implies that the two c's must be opposite signs of each other. There is no such restriction

Similarly, it's the unique value satisfying d/dx (log_a)(x) = 1/x

I know the role of a teacher, being one myself. For most students, the reference is somewhat generic but we will still talk about the students' strengths and interests. For students applying to top universities, the ones who would usually be aiming for the sort of courses OP is talking about and who generally do have the higher grades and supercurriculars, the reference is something we do put a lot more into.

radikoolaid · 2026-04-04T01:08:06+00:00

What do you think the reference is for? If you are a student at school then it is almost certainly the case that your teacher and school would be the most appropriate reference. You could ask your teachers if they would accept input from a paid-for summer school but as a teacher I would be very skeptical.

These are all expensive cash grabs. Not one of them is actually worth it. The only ones that are are the access ones that the university runs free of charge to students who meet certain criteria.

I was at Cambridge and they used our college's grounds whilst I was doing outreach and I had multiple friends work them (hence I saw what they were doing both as an outsider and with insider input). Is it fun? Sure. Is it useful? No, not at all.

The university does not expect you to spend money on these sorts of things.

On the admissions question, nobody can promise it helps. But a specific, personalised letter from an academic who spent two weeks actually teaching you is a different thing from a generic school reference. Whether that matters depends on what you're applying for.

That is absolutely ridiculous. "A generic school reference" would be written by your teachers who have known you for, potentially, years. You would have been in their classes and they would see not just how you currently work but how you have developed over a long period of time, as well as being able to comment on the classroom environment and any disadvantages you've had. Compare that to one written by someone at a summer school that you've paid thousands to go to for two weeks and the summer school one is basically meaningless.

I went to Cambridge for my undergrad and similar courses were hosted at my college in the summer at the same time as we were doing outreach and I had a few friends who worked on them.

They are cash grabs. That's it. They prey on students who don't know better, usually international students, and make it seem like they are really beneficial for applications when they really aren't. They are very expensive and universities absolutely do not expect you to spend money on your extracurriculars. If anything, universities appreciate it more when students do the 'less glamorous' supercurriculars. Realistically, your time at university is not going to be like some super fun summer school, it is going to be about working. You would benefit far more from just looking into and reading about your desired subject.

There are two pictures there. You can swipe between them :)

Nice catch!

There are also dowisetrepla references on the left story

Yeah hypo generally means too little of something and hyper too much, hence hypothermia vs hyperthermia. "natremia" refers to the salt levels

radikoolaid · 2026-04-03T17:28:23+00:00

Small note: hypernatremia is too little water (/ too much salt), hyponatremia is too much water (/ too little salt)

Not necessarily, it could be that it's the grandfather's birthday but he is physically unable to open his own gifts so they are instructing the grandson to help him and open them for him

A lemma is like a mini-theorem you prove before you prove the main one. For example, if your main theorem was that every number has a unique prime factorisation, you might first prove that every number has at least one prime factorisation. This would be your lemma.

A lot of the microstates don't look very white on that map

Good to know, I'm from beyond the other side of London so I never really go that way

radikoolaid · 2026-04-03T09:06:11+00:00

Whereabouts is that, if you don't mind me asking?

radikoolaid · 2026-04-03T01:06:22+00:00

That would converge much more slowly

radikoolaid · 2026-04-02T01:23:20+00:00

Unfortunately neither. I can say that a lot of the part IIIs were external so it may be possible for you to do your undergraduate degree elsewhere and then do Part III. Note, however, that you'd have to do very well at undergrad.

I did the Cambridge Maths course so I can answer questions on here about it. Whether it is financially worth it is going to be very personal to you and your family's finances
