This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

@Jason Gomez I wanted to reply this to Eric Roberts for his harsh comment towards Ram Mohith, Just chill

- 1 month, 2 weeks ago

@Percy Jackson dont get mad as it is by tseries, bcuz tseries is one of the big music labels in india just like vevo is worldwide.

- 1 month, 2 weeks ago

why would i get mad? I don't hate t-series as such, just support Pewds more in the YT war.

- 1 month, 2 weeks ago

- 1 month, 2 weeks ago

I wanted to but not really so I didnt mention 😬

- 1 month, 2 weeks ago

harsh comment? where?

- 1 month, 2 weeks ago

It’s gone, you are always late, how can someone like you with no discipline become praetor, smh

- 1 month, 2 weeks ago

Unlike you, I actually have a non-online life, so I can't be on brilliant all the time :)

- 1 month, 2 weeks ago

My offline life is now just full of exams and studying old stuff(nothing to refresh my brain) so I come here quite often as practically I am dying inside.(Can’t even play with friends, haven’t played in real life for 12 months, I would have sliced that thought up 2 years ago and now it’s the reality)

- 1 month, 2 weeks ago

but congratz: your "cheese press" solution is still number one.
btw: the springs look great. how did u create them?

- 1 month, 2 weeks ago

lol, now i feel 'springrolled' ;-)
but they look very tasty.

- 1 month, 2 weeks ago

lol nice wordplay :P

- 1 month, 2 weeks ago

Nice rolls

- 1 month, 2 weeks ago

lol

- 1 month, 2 weeks ago

By hand, it’s quite surprising it’s first too, I didn’t even do all the casework

- 1 month, 2 weeks ago

ahahah, lol, did u do the new dc?

- 1 month, 2 weeks ago

Yeah,didn’t want to put up a solution

- 1 month, 2 weeks ago

I made a new question, if you want a challenge after today’s dc, you may do it, no calculator, no program, no google, no bing, only pen and paper required

- 1 month, 2 weeks ago

solved it and posted solution :)

- 1 month, 2 weeks ago

wow, they look very symmetric.
you continue to impress me with your skills.

- 1 month, 2 weeks ago

Lol that was copy and paste, I just made one by hand

- 1 month, 2 weeks ago

Man, that's depressing...seeing as my life is half playing multiplayer games with friends and half studying...lol

- 1 month, 2 weeks ago

All of my friends who are of my age are in twelfth (like me), so no multiplayer games here, and all my friends who are older than me are allowed to go outside, I am just stuck at being the wrong age at the wrong time.

- 1 month, 2 weeks ago

lol I'm so glad I have friends who play FNite and MineCraft

- 1 month, 2 weeks ago

i don't get the meaning of 'twelfth'. how does that cause u to have no multiplayer games?
i'm very bad at FNite, but tbh i spend too much time on gaming, so i'm glad to have brilliant, that causes me to use my brain in a favorable way.

- 1 month, 2 weeks ago

I am in twelfth standard(twelfth grade in Germany) and in India this is a crucial time, cause depending how good you do in twelfth, you get a good college(overpopulation and very few seats is the major problem)

- 1 month, 2 weeks ago

ty. i assumed that but twelfth graders in germany are usually about 18 years of age.
is that different in india?

- 1 month, 2 weeks ago

I am 17 actually not 15 btw

- 1 month, 2 weeks ago

ok that makes sense.
it sounds like a hard situation. are there measures against the overpopulation?

- 1 month, 2 weeks ago

Nope

- 1 month, 2 weeks ago

Problem is that most of the children born, are born into poverty, so since most of the population is in poverty, there are reservations in place, disproportionate reservation, and it’s only to backward castes and not to below poverty line, so getting seats in general gets all the more harder(they are also doing stuff like if you have a reservation and you get a good rank you will be taken out of reservation and someone else will take that place, as if general doesn’t get enough seats already, being a boy makes it even more harder, a girl getting a good rank gets her a better place than a boy, but seeing that most toppers are boys, the reason is justifiable)

- 1 month, 2 weeks ago

More reservations, more votes, that’s the mantra of all governments in India( in no way am I saying it’s bad, I am just saying it’s highly disproportionate)

- 1 month, 2 weeks ago

afaik a good way to reduce overpopulation is a higher education.
but assume it's a slow way.

- 1 month, 2 weeks ago

lol do the others in this thread understand the caste system like what is general, backward, etc. If your name is really Jason Gomez then aren't you considered minority, I don't know if they have reservations rights or nothing like the general.

- 1 month, 2 weeks ago

I am a Christian, there’s no reservations for minority, I can easily apply for OBC, but didn’t because I want to be in general, I feel it’s cheating to take advantage of your caste if you are well to do and don’t require it. There are many others I see who take advantage of this, personally I feel like kicking them, reservations should be shifted to below BPL in my point of view

- 1 month, 2 weeks ago

Yeah this corrupted caste sytem sucks, some of the bigotreous people who call themselves Hindus do not follow the real caste system which is actually flexible, where even Lord Krishna himself said your caste depends on what work you do not on your birth, but due to British and Manusmriti it is all corrupted now ughh.

- 1 month, 2 weeks ago

There was a point of so much reservation that to get into Indian services you needed to get more than -11, meaning you leave the answer sheet blank and you get in(it’s considered to be a very hard exam, I have not seen what they need to study, but it was easy to see that the reservations are not justifiable)

- 1 month, 2 weeks ago

Do all you Indians type a lot more about your country than necessary @Siddharth Chakravarty, @Jason Gomez???

- 1 month, 2 weeks ago

When there’s a lot happening in the country, there’s a lot to type about it as well

- 1 month, 2 weeks ago

Yeah, like coronavirus.

- 1 month, 2 weeks ago

That’s was one thing India handled with how much it ever could, it was bound to spike up, but it was considerably prolonged and we didn’t have the massive death figure as I had expected

- 1 month, 2 weeks ago

Yeah, but do you need to tell us everything? I mean, I could tell you how Texas is dying of freezing, but I didn't coz it's not useful or comforting to know...

- 1 month, 2 weeks ago

Well this rn is the direct obstacle in my path, due to which my twelfth is hard, related to what num asked

- 1 month, 2 weeks ago

I don't care. Just type short messages. Helps get rid of notifs quicker.

- 1 month, 2 weeks ago

so thank you for telling.

- 1 month, 2 weeks ago

It is better to type long discussions bcuz I have seen many of my foreign friends keep on asking question for short answers as many of the things like caste sytem are unknown to them, and that would increase the thread and notifications instead a long answer would answer most of the questions.

- 1 month, 2 weeks ago

Hmm...its a way better answer than Jason, and a good answer in general, so I'll accept it.

@Jason Gomez - Why can't you answer like Siddharth?

- 1 month, 2 weeks ago

Let me make this simple:

Me

Siddarth

Two different people

Two different minds

Two different environments

- 1 month, 2 weeks ago

You don't get what I'm saying. Look, no offense but tbh I don't care about what's going on in your country. Just because there is a lot going on doesn't mean you type it all out like an essay and send. I don't give you essays on America, just because America exists, right? Your answer just doesn't make sense. Siddharth's answer on the other hand, perfectly understandable, he states a logical reason as to why he types more. I am not asking you to give the same answer, just something logical. Also, a little brevity never killed anyone...

- 1 month, 2 weeks ago

Ok Percy I understand, no more India from me anymore

- 1 month, 2 weeks ago

No, no, its fine, you don't have to stop responding to num's questions. Just try to shorten the answers, that's all :)

- 1 month, 2 weeks ago

I see that you think I took it in a bad manner, I didn’t , be in peace boy

- 1 month, 2 weeks ago

Pfft...no I didn't, I was just being logical. ☮ Peace :)

- 1 month, 2 weeks ago

ty for this insight Jason.

- 1 month, 2 weeks ago

I just play a lot of FNite, doesn't mean I'm good at it. I never got a victory royale on my own. Always got killed by some pro gamer. Minecraft on the other hand, I'm pro at. I've beat it 2-3 times with some constraints that most youtubers apply.

- 1 month, 2 weeks ago

nice. i've only played minecraft a bit. it's nice but i was not aware that there is a goal ?

- 1 month, 2 weeks ago

Yeah there's a dimension called the End in MC where you go to beat the final boss. Basically you've got to collect some materials like Ender pearls and blaze rods, get diamond armor and tools, and find a dungeon. Inside the dungeon is where the End portal is. After arriving in the end, you have to beat the Ender Dragon. Once it's dead, you get an ender dragon egg. Then you can leap into the portal and the credits roll.

- 1 month, 2 weeks ago

ok. sounds interesting. ty

- 1 month, 2 weeks ago

I have come to the point where I am thinking in either a French accent, and Indian accent or an American accent. I’m not sure if that is normal, as I speak in a British accent, but I think in another. I have to consciously force myself to think in a British accent. Anybody else having this problem or am I gradually going mad? (I have just now realised, before I post this, that I thought this all in an American accent)

- 1 month, 2 weeks ago

when i talk in or listen to english for a long time then i think in english too,
so i assume there is nothing to worry about.

- 1 month, 2 weeks ago

Thank goodness. I was worried that I had that disease where you speak in an accent which you have never heard before. I can’t remember the name, though.

- 1 month, 2 weeks ago

you sound very concerned. did you ask a doctor?
for me it's just impressive that you can speak so many languages
but if you are concernced, maybe a professional advice can relieve you better than our private opinions.

- 1 month, 2 weeks ago

I can speak Bengali and English, also a little bit of french but I mainly think in English. I just think in those particular accents. (Indian, french, and American). I don’t think it’s a serious disease, but i guess it is like what happened in ‘Three Men in a Boat’. The man didn’t know he had any diseases until he read about the disease and thought that he had all the symptoms. His doctor told him that “don’t talk about things you don’t understand” or something. I think I only think that I have this disease because I watched a video about it.

- 1 month, 2 weeks ago

Why are you concerned over in what language or accent do you think or speak, what matters is what you think.

- 1 month, 2 weeks ago

I just didn’t think it was normal.

- 1 month, 2 weeks ago

yeah it happens that one assume to have a disease after reading about the symptoms.
my private opinion is that it is normal to think in other languages.
but as i said: if you are still concerned then a real doctor can relieve you.
i assume that you anyway sometimes visit a doc, so you could just ask him at your next visit.

- 1 month, 2 weeks ago

My doctor is female.

- 1 month, 2 weeks ago

I speak and think in both the same Indian accent albeit I can mimic the other ones.

- 1 month, 2 weeks ago

It’s very normal, in India most people think in just one language and speak in all other languages, I normally think in the language I am speaking in (sometimes not for Hindi), but sometimes I think in English and speak in my mother tongue or vice versa, and in those situations, I start to create new words

- 1 month, 2 weeks ago

What words?

- 1 month, 2 weeks ago

If I am playing something and my dad asks what I am doing suddenly, instead of saying ‘valaditta irrukae’, I would say ‘valad-ing’ ( valadae means play, the itta has no specific meaning I think, irrukae means now )

- 1 month, 2 weeks ago

Oh, that sometimes happens to me if I don’t know a word in Bengali. I usually just mix the root word with an English suffix.

- 1 month, 2 weeks ago

to avoid spamming the daily challenge chat, you can just post your tests here.
$\large{ \text{🔵🐠 🐜🔺}}$ [edit: spell correction]

- 1 month, 1 week ago

I don't understand how you can think in an accent...like when you think in a French accent, do you think about cheese, bread and weird pronunciation? Do you think about conquest and the queen when in Bri'ish mode? I'd say you probably think about anything other than refrigerators in Indian mode, since Indians don't know what those are (@Siddharth Chakravarty lol). I don't know what you'd be thinking about in an American accent tho, which is ironic since I'm American...

- 2 weeks, 3 days ago

what is a refrigerator, please enlighten me on this.

- 2 weeks, 3 days ago

A fridge. An appliance or compartment which is artificially kept cool and used to store food and drink. Modern refrigerators generally make use of the cooling effect produced when a volatile liquid is forced to evaporate in a sealed system in which it can be condensed back to liquid outside the refrigerator.

- 2 weeks, 3 days ago

looks like u didn't get the joke, anyway it was between me and Percy.

- 2 weeks, 3 days ago

Okaaaaaaaaaaaay... so why did I give you the definition?

- 2 weeks, 3 days ago

- 2 weeks, 3 days ago

I don’t know. I don’t have a great memory, and I usually can only remember random things, like the colours me and my mum’s friend used in a colouring book when I was like, five.

- 2 weeks, 3 days ago

From inside refrigerator joke, to Sarah's five year old coloring books in a matter of 7 comments. Great going guys, you beat the record for quickest and weirdest topic change lmao

- 2 weeks, 3 days ago

I bet I can change the topic again. Well, I don’t gamble. This is a metaphorical bet. I’m not going to give you money if I lose.

- 2 weeks, 2 days ago

You know, gambling reminds me of poker. I think that’s what it’s called. Me and my mum played poker twice. (Without money) Or thrice. Is that a word? Anyways, she called it ‘bluff’.

- 2 weeks, 2 days ago

I'd be 'bluffing' if I said I understood even half of that lmao

- 2 weeks, 2 days ago

So you understood more than half, or less than half?

- 2 weeks, 2 days ago

more

- 2 weeks, 2 days ago

Are you bluffing? I can’t tell, you typed it.

- 2 weeks, 2 days ago

Just joking. Don't bother lol

- 2 weeks, 2 days ago

Please, take all of our prize money for weirdest and quickest topic change...

- 2 weeks, 2 days ago

Thank you. I love winning. 😄

- 2 weeks, 2 days ago

lmao

- 2 weeks, 2 days ago

Yes, yes. It is between me and the guy who doesn't know about refrigerators.

- 2 weeks, 3 days ago

Ah, you are Indian I see. Well, a refrigerator is big box thing, keep stuff cold. Did you understand that you primitive life form? lol

- 2 weeks, 3 days ago

My thoughts don’t change, just my accents. Once I began speaking in a French accent to my sister by accident. She looked at me weird and went away. I mean, I think about weird things, like why bread comes sliced nowadays. When I think about American things, I don’t always think American. The french accent comes from setting most of my games to french (I’m trying to learn it, I’m terrible at learning new languages through memory. Usually, it comes from reading in that specific language, that’s how I learnt English - it’s not my first language) the American accent comes from most of the shows and movies I watch, and up the english accent comes from growing up with my British friends and teachers.

- 2 weeks, 3 days ago

Okay. I did not read any of that, but I bet its some really valid reason, so I'll just agree with you lol

- 2 weeks, 3 days ago

I'd say you think about anything but cricket in American mode.

- 2 weeks, 3 days ago

I barely ever think about cricket. Or any sport. I’m terrible at sports. The only sport that I am a little good at is rock climbing and chess. Rock climbing a little more than chess.

- 2 weeks, 3 days ago

Rock climbing? Is that even real?

- 2 weeks, 3 days ago

Yes... I used to scale rocks and go to mountains before coronavirus. Sometimes the walls were artificial and I had to get there first. Search it up, it’s real. There was also one where I had to climb up and extreme obstacle course, race across the bridges, ropes and bars and then go down a ninety metre zip line.

- 2 weeks, 2 days ago

Cool. I have also climbed mountains. In Minecraft...

- 2 weeks, 2 days ago

Oh. I have played Minecraft a total of three times. I was talking about real dangerous things, like jumping off physically. That was fun.

- 2 weeks, 2 days ago

Yes, jumping off a cliff is loads of fun. The thrill, chances of death...oh so fun...lol

- 2 weeks, 2 days ago

I was harnessed to a rope, and I was nine. I still find jumping off high places fun.

- 2 weeks, 2 days ago

Yea...I'mma go now...bye.

- 2 weeks, 2 days ago

You are right primitive life form. Who needs to think about people swinging bats and hitting balls, when you can think about American people swinging bats and hitting balls.

I meant baseball if you didn't get that.

I prefer being Duckrolled....Cheesy Rick Astley? Really? The boy with the manly voice. Darn, if there's one thing I hate about the 80's......

- 1 month, 3 weeks ago

It is kind of strange. He has such a low and deep voice, but he looks like a twelve year old.

- 1 month, 3 weeks ago

Always has, even when he was with F.B.I. Must have scared the crap out of his parents when he spoke his first words.

- 1 month, 3 weeks ago

He was with the FBI? I thought he was just some weird singer.

- 1 month, 3 weeks ago

That's just a cover that turned out to be very successful.

- 1 month, 3 weeks ago

ty for mentioning me. why does the link lead to a yt-vid?
anyway: no need to link to my empty chat.

- 1 month, 3 weeks ago

Maybe in Germany, this doesn’t exist?

- 1 month, 3 weeks ago

? it leads to that video: 'Rick Astley - Never Gonna Give You Up'
i don't get how this would be connected.

- 1 month, 3 weeks ago

I don’t know how to explain this to you, but it’s a rickroll, umm.. somewhat like an April fools prank

- 1 month, 3 weeks ago

ok. ty. this vid has 800mio views, so he is making a lot of money with it

- 1 month, 3 weeks ago

If someone sort of pranks you with showing you the song like in a zoom meeting, then you’ve been Rick-Rolled and same thing if someone like, gives you a link to a ‘Never Gonna Give You Up’ video. It is basically an unexpected appearance of the video.

- 1 month, 3 weeks ago

thank you. i was not aware of that.

- 1 month, 3 weeks ago

I didn't know that either, never even heard of it. Must have been something Ricky boy came up with himself, the sly old marketing fox. I mean, that song is how old now? And has it ever been good?

- 1 month, 3 weeks ago

It’s a good song, I guess. But Rick didn’t actually make it. It was originally a meme where people have a misleading link to ‘rickroll’ them. It’s pretty funny sometimes.

- 1 month, 3 weeks ago

I haven't clicked the link yet...I'm suspicious because I never saw Num IC's chat note, even though I check his notes sometimes...

Edit 1 : found out its a yt link by hovering over it...suspiciously seems like a rickroll, seeing as I pulled one some time ago...

Edit 2 : my suspicions were true! num IC mentioned the Rick Astley vid! I am 1000 IQ big-brained bois!!! You can't prank me!!!

Edit 3 : @Jason Gomez

- 1 month, 3 weeks ago

Ik and uk what happened

- 1 month, 3 weeks ago

Yes, and that is that I didn't get rickrolled. Please, we were on the topic just some time ago, I'm not that stupid. Also, my friends on repl.it rickroll so much, I always use the JS preview that comes for links to be safe.

- 1 month, 3 weeks ago

Okay, then I’ll get you in some other way

- 1 month, 3 weeks ago

Hehehe, I'll watch out :)

- 1 month, 3 weeks ago

And Num IC did have a just chat note up, and it was there for a few days, Ik u saw the note first

- 1 month, 3 weeks ago

I didn't actually see his note. Just saw the lack of it. Got deleted by staff seemingly, according to num IC.

- 1 month, 3 weeks ago

BM will prolly delete this...chatting's not really promoted on this site...

- 1 month, 3 weeks ago

my chat note was empty. and now it is gone. maybe the staff deleted it bcs it was empty.

- 1 month, 3 weeks ago

probably...and that will happen to this chat too

- 1 month, 3 weeks ago

Ok then lets have a science/math discussion, what are the math/science problems you saw in real life as a kid and couldn't solve them at that time. Here's the link to L-Tetramino where me,Chris Lewis and David Vreken started this conversation.

- 1 month, 3 weeks ago

april fools day is not today

- 1 month, 3 weeks ago

I plan for things which are gonna come(not at all, I am a very bad planner :P)

- 1 month, 3 weeks ago

:-)

- 1 month, 3 weeks ago

Has your notification bar being acting up? It doesn’t show anything for me if I don’t have any notifications

- 1 month, 3 weeks ago

yes

- 1 month, 3 weeks ago

Okay so it’s mostly an issue everyone is facing, so no need of asking BM to do something about it

- 1 month, 3 weeks ago

by yes i mean: if there is a new notification then it shows the number and i can view them.
what issue do you have? (it sounds like it might be related to some browser settings)

- 1 month, 3 weeks ago

- 1 month, 3 weeks ago

The notification bar disappeared, and doesn’t come at all, only if I have a new notification does it show up, so no damage in that way

- 1 month, 3 weeks ago

ah now i got what you mean: my notification bar is vanished now.
i assume the are doing some update.

- 1 month, 3 weeks ago

now it seems to be ok again.

- 1 month, 3 weeks ago

Hmm mostly, do you face the same issue?

- 1 month, 3 weeks ago

hm, yes. if there is no new notification it does not show up at all.
thats a pity bcs i use it as a reminder if there is a post that i want to check again or more deeply.

- 1 month, 3 weeks ago

The link isn’t working for me. Is that normal?

- 1 month, 3 weeks ago

thats why i said today is not april fools day.
its no link. he just changed the text color

- 1 month, 3 weeks ago

I was wondering why it was in latex. Can’t believe I didn’t think of that.

- 1 month, 3 weeks ago

can you see that directly?
i'm on a windows laptop and for me it's just blue (slightly different than a real link).
after your comment i copied it to see the latex part.
how to see it without copying?

- 1 month, 3 weeks ago

I think the font is just a little different for me. I’m on a phone by the way.

- 1 month, 3 weeks ago

Strange, I have no problem with the link. It takes you here: https://brilliant.org/problems/l-tetramino/

- 1 month, 3 weeks ago

Strange, when there was no link placed in the first place

- 1 month, 3 weeks ago

maybe you where not rickrolled, but at leaat you got pranked now ;-)

- 1 month, 3 weeks ago

@num IC ?.? I made that comment ?.? How do you get fooled by your own comment?.?

- 1 month, 3 weeks ago

So where did S Broekhuis get the link from?

- 1 month, 3 weeks ago

From my problem… check my profile you should realise, and the link works for real now, click it and see

- 1 month, 3 weeks ago

Yeah, I got to the link.

- 1 month, 3 weeks ago

yeah. nice problem. i solved it manual. i love the way David solved it general.

- 1 month, 3 weeks ago

I had been solving that problem manually for years, lol

I used to lie in my bed watching it snow outside, wondering about how many symmetries a snowflake has. I was just a wee lad of about 4 years old back then, so naturally I didn't have a clue about 3 dimensions and how they work together.

- 1 month, 3 weeks ago

Nice you tried a part of group theory from four, very impressive

- 1 month, 3 weeks ago

Nonono, not group theory just the symmetries of a single snowflake. I didn't get to wonder about group theory until we had rabbits, which I think was when I was around 6.

- 1 month, 3 weeks ago

Okay I put the link now, I wasn’t able to get the web address through my phone I was using yesterday, so thought I’ll just do this

Okay I am taking out the rickroll now, in fear I might rickroll myself (I haven’t been rickrolled(I call a rickroll, a rickroll if it’s a total surprise) yet), and have no intention in feeling the embarrassment of rickrolling myself.

I just used this command \color{random} in my new problem and it didn’t give an error, but always shows the colour black to me, do you guys see it in different colours?

- 1 month, 3 weeks ago

$\color{random}{\text{This too is in supposedly random color}}$

- 1 month, 3 weeks ago

$\color{random}{\fcolorbox{random}{random}{\text{This also}}}$

- 1 month, 3 weeks ago

i'm not sure how random works in LaTex. in other languages a funktion is used to generate pseudo-random values. so if the function is started, it always starts with the same numbers in the same order.
therefore an initial value can be given to create a more random looking value. often the time is used for that.
anyway: if you can access the current time in ms then you can just use the last digits to create a somehow random value.

random is not a latex code, so usually if latex doesn't recognize a color code, it goes to default a.k.a black.

\color{why_does_it_not_do_the_same_with_this}{\text{I should have written that here}}

$\color{color}{\text{no symbols i guess}}$

\color{./0][}{\text{no symbols i guess}}

- 1 month, 3 weeks ago

$\color{hello}{\text{see}}$

- 1 month, 3 weeks ago

Wait what \color{random1}{\text{huh}}

- 1 month, 3 weeks ago

no numbers and symbols, only letters allowed

- 1 month, 3 weeks ago

Ok that makes sense

- 1 month, 3 weeks ago

I found some forum's and youtube videos on the random latex topic, here are the links -

StackExchange - Random colors in Latex 1

StackExchange - Random colors in Latex 2

Everything to do with color in Latex - Video

All about font color in Latex - Video

The videos just talk about \xcolor in latex documentation, and only the forum really explains random-color codes, but none of that works on Brilliant I guess.

Also check out this zoom rickroll :)

- 1 month, 3 weeks ago

I clicked the zoom rickroll first, then it showed me a video about latex. I then started looking for the rickroll in the links. I see what you did Percy.

- 1 month, 3 weeks ago

Here's a first, someone really wanting to be rickrolled

- 1 month, 3 weeks ago

I thought there was no rickroll and that was the prank, but lol thanks to Percy himself I didn’t get rickrolled lol

- 1 month, 3 weeks ago

I'm gonna play some 1,000,000 IQ games on you now, seeing as you passed the 1000 IQ challenge...

- 1 month, 3 weeks ago

Bring it on

- 1 month, 3 weeks ago

hehehe

- 1 month, 3 weeks ago

I didn’t want to be rickrolled, but I did want to know which one was the rickroll. I wasn’t on brilliant for half a day and now I have 90 notifications. 90, people! (89, but who’s counting?) What were you guys doing?

- 1 month, 3 weeks ago

And why did you delete half of them?

- 1 month, 3 weeks ago

sry.
when this happens i just read the chat and then delete all notifications from the participants. that might cause that i miss something that was regarding another topic.

- 1 month, 3 weeks ago

Actually, I like reading comments. That’s why I’m kind of frustrated when their deleted. I’m just curious by nature. I need to know a lot of things. My ‘fatal flaw’ would probably be my curiosity.

- 1 month, 3 weeks ago

i fully understand. i'm quite curious too.
but sometimes it's very time consuming to read all that was posted. (tbh i had to learn quite a lot of self-discipline to avoid checking all notifications.)

regarding deleted posts: every correction of a post creates a new notification but only the newest one leads to the post.
so you were mainly missing wrong spellings or changed wordings.

- 1 month, 3 weeks ago

Oh, I thought that I was missing out on something that could change my life. (That was over-dramatic, but still)

- 1 month, 3 weeks ago

sure u missed some life changing wise words from the demi-god ;-)
and did you check Jasons challenge with the 10000 cars?

- 1 month, 3 weeks ago

My profile picture is Reyna from Heroes of Olympus, drawn by Viria from tumble. I did see Jason’s challenge, but the wording was a little confusing for me. I didn’t really get the question.

- 1 month, 3 weeks ago

oh it seems i missed a lot. i was not aware how far this series is extended.
if you are interested in calculating probabilities, i can explain the car task in other words.

- 1 month, 3 weeks ago

That would be so nice of you. I’d like it if you do that. I was never that good at understanding probability, something I share with my mother.

- 1 month, 3 weeks ago

Bellona sucks at probability? lol

- 1 month, 2 weeks ago

I don’t get it. Bellona is the Roman goddess of war, not probability.

- 1 month, 2 weeks ago

but...she has to be smart right? War has strategy, and strategy involves considering multiple possibilities aka probabilities. Ares shouldn't know probability. I'd be surprised if he even knew what a number is...

- 1 month, 2 weeks ago

I think you’ve mixed her up with Athena.

- 1 month, 2 weeks ago

No he hasnt

Moderator Note : The Bandwidth is extremely low on this comment, you have to start another main comment if you want to continue

- 1 month, 2 weeks ago

fine dude...i posted a new comment...also, I don't think its bandwidth...

- 1 month, 2 weeks ago

i like to explain it. i just wanted to avoid explaining it without beeing asked for.

in other words: if you pick a random number between 0 and 9999
and then i pick a random number between 0 and 9999
and i repeat that 10000 times.
what is the probability that your number matches at least one of my numbers?
(i can guide you step by step through the solution if that was your intention.)

- 1 month, 3 weeks ago

So this is going by that you may pick the same number twice?

- 1 month, 3 weeks ago

If so, I’d presume it’s about 63% If not, 100%

- 1 month, 3 weeks ago

wow great. you are right: if i could only pick different numbers then it would be 100%. (but that would be too easy ;-)
can you explain how you calculated the 63%

- 1 month, 3 weeks ago

I didn’t actually calculate it. I asked my dad and he gave me the answer. Vaguely. He also mentioned that the question didn’t make much sense and so I sort of cheated. I don’t actually know how it was solved.

- 1 month, 2 weeks ago

You are too on point to have just guessed that, are you sure you are (palindrome) bad at probability

- 1 month, 3 weeks ago

yeah like Jason says: you got that 63% quite fast. this kinda contradicts that you are "not good at understanding probability" ;-)
that's why i asked how u calculated that 63%

- 1 month, 2 weeks ago

sry, we're having a prank contest, me and Jason. We're gonna stop now, at least I am, dunno bout Jason.

- 1 month, 3 weeks ago

A Brilliant prank competition? How many pranks can you do online? I’m sure there aren’t that many. And is it really a prank contest if only one (or none) of you participate?

- 1 month, 3 weeks ago

If we keep it everyday then it will get boring and all of you guys will be getting 259 notifs, so it will start up once in a while

- 1 month, 3 weeks ago

Yeah :)

- 1 month, 2 weeks ago

Yeah you are not allowed to use packages in brilliant, if we could, I can't imagine what you would do with it

- 1 month, 3 weeks ago

Yeah and also, you got rickrolled. Not even Einstein can figure out that one.

- 1 month, 3 weeks ago

I just realised that the fourth video was a rickroll, I didn’t see it till now, I saw only the first,second and the zoom rickroll, so that’s what Sarah was talking about, I thought she meant that there was no rickroll, and btw you used the original one it ends in XcQ

- 1 month, 3 weeks ago

Yup it’s the original, lol Percy you couldn’t beat me( maybe if you put it two days later, I might have clicked it by then, I had checked the first two for rickrolls but would have forgotten today\tomorrow)

- 1 month, 3 weeks ago

Well...fine, watch out for bigger-brain tricks then...

- 1 month, 3 weeks ago

I got one up my sleeve now, but I love surprises more so you will have to wait

- 1 month, 3 weeks ago

k fine

- 1 month, 3 weeks ago

Better than Einstein lol

- 1 month, 3 weeks ago

obviously everyone alive is better than Einstein, the guy's frickin dead

- 1 month, 3 weeks ago

he got me first, but i deleted my reply to avoid spoiling it.

- 1 month, 3 weeks ago

Lol he spoiled it himself

- 1 month, 3 weeks ago

We're still on 0-0, neither has a point...I'm gonna get you...

- 1 month, 3 weeks ago

Notifs been acting up lately. Seems like new update. Also, they removed the View Mobile Site/View Full Site buttons. I kinda liked the previous look better.

- 1 month, 3 weeks ago

So that’s how you used to message to those “no bandwidth replies”, I always changed devices lol

- 1 month, 3 weeks ago

yeah lol now i can't reply to nico's invisible messages :P

I can still copy paste the thing and paste it somewhere to read, but I'm too lazy to do that...

- 1 month, 3 weeks ago

I have unsubscribed...all of you collectively are giving me too many notifications.

- 1 month, 3 weeks ago

No worries will @ you when required

- 1 month, 3 weeks ago

k

- 1 month, 3 weeks ago

Could you guys try out my new problem, it shows that six people attempted and failed, and it is supposed to be an easy-ish problem, is there any problem with the problem statement or have I got the answer wrong?

- 1 month, 3 weeks ago

should the answer be given in % or just a probability?
my first guess was 0.368 but i forgot something.
now i got it.
and i did it the same way as you showed in your solution (without the extend to infinity).

- 1 month, 3 weeks ago

Just a probability, percentage is used only when asked I thought, I’ll make that more clear

- 1 month, 3 weeks ago

does indian number plates use leading zeroes?
maybe ppl assume a trap and exclude the numbers from 0 to 999.

- 1 month, 3 weeks ago

Sometimes they don’t but normally it’s kept, that’s the reason I put 0000 to 9999 so that all numbers below five digits are included

- 1 month, 3 weeks ago

;-) you asked why ppl might have failed. i just made some proposals.
but overal in my opinion your wording was good, so the failures might just be misscalculations.
maybe Sarah has an idea to improve the wording, but as i said: in my opinion your wording is good. and i like that challenge very much.

- 1 month, 3 weeks ago

strange. it seems my comment to your (Jason) 'Bouncing up' solution was deleted by the staff.
i have no idea why.
