Finn Hulse's Messageboard

Does your school have a strange schedule/lots of free periods? You seem to be able to get to a computer at all times of the day, I've been curious how you manage that with school/homework.

What do you like to do except "Brilling".!

What is there to do in Willamsburg?

are you really 13 years old? :D

Finn Hulse .....hv guts attempt this

@Finn hulse How/when you noticed you're smart in (math/physics &others...) at the first time ? How did u feel then? :)

Hi @Finn Hulse , it seems like you are very eager to be on the "People to Follow", hope you won't want to bite my head off for taking the place, haha. What I want to say is, "People to Follow" isn't a place to get attention, nor judging your achievements/ability. You are doing great and the "People to Follow" doesn't matter very much actually! Keep up your great job, cheers!

You should get an AoPS account.

Hey, I am not god! :P

man! finn hulse! u r juss 13 yrs old nd u solve so many problems of higher levels with ease...! gr8! :) salute

Happy (belated) birthday Finn!!! Finally 13 :D I'm turning 13 in twelve more days (May 18)...

Happy (probably belated) birthday, Finn!!!!! You're 13 and a teenager!!! I have 7 more months to wait.

@Finn Hulse Congrats on your level 4 and level 5 on all subjects especially calculus.

Hugh Everett hypothesized that objective reality is actually many worlds, every event being a branch point spawning ever more possible worlds, so that in one world, the cat is alive, and in another, it's dead. Would you be a confirmation of that hypothesis, being that you seem to be everywhere and doing everything all at once?

Hi Finn have you noticed that it is showing that you have followed only 51 members. Actually you had followed around 3000+ I suppose?

@Sharky Kesa @Trevor B. That was the most freaking boss game of FTW! ever! We have to do that more. :D

@Daniel Liu @William Cui @Franklyn Wang @Akshaj Kadaveru @Nicky Sun You guys! Good luck at Nationals! I can't wait to watch the CD round on ESPN! It's going to be so intense! Watch out for Colin Tang! :D

@Dan Lawson Would you mind writing a solution to Plugging Roots into Functions? I'm really interested to see your technique. :D

@Yan Yau Cheng When will JOMO 4 results be released? I really want to know how @Emery Shelly and I did! :D

@Jon Haussmann @Daniel Liu @Pi Han Goh @Ashtik Mahapatra @Calvin Lin @Dinesh Chavan @Gabriel Merces @David Lee @Xuming Liang @Akshaj Kadaveru @Christopher Boo @Sharky Kesa And all others, try to solve and post a proof/solution to Two Maximized Constants in an Inequality. Good luck! :D

@Calvin Lin Could you boost the rating of Dominoes and Chessboards to like, 2200? It's pretty insanely tough until you realize the trick and then it's (moderately) easy. Good luck solving it! :D

Congratulations @Christopher Boo for beating me in terms of followers! I knew you would eventually, especially since you made "Who to Follow" and I didn't. Well, well, I guess I'll never be as good as you.

@Peter Taylor I'm happy to see that new bar where you can access solutions! I'm glad I don't need to upgrade to Brilliant Squared to have access to this decent little feature!

@Peter Taylor With the new solution-viewing format (where you can see what solutions you've posted) I had a "Brilliant" thought. What if when you viewed the page, beside each solution, it showed how many upvotes it had? Also, will you guys make it so we can view everybody's solutions, not just our own?

@Finn Hulse I found someone who follows more people than you: @Santanu Banerjee

@Emil Svensson Do you actually live in Williamsburg VA?

@Calvin Lin Have you actually received my email? Sorry to bug you, but I'm interested to see your reaction. :O

@Calvin Lin How is the rating for Plugging Roots into Functions Level 3? Only 16/32 people have solved it which should make it Level 4-5. :/

@Yan Yau Cheng I have a much simpler proof for problem #5.

Question Statement:

Given that $p$ and $p^2 + 8$ are both primes , what is the sum of all possible values of $p$?

Solution:

We can see that if $p \equiv 1$ or $p \equiv 2 \pmod{3}$, then $p^2$ will be congruent to $1$ or $4$ modulo $3$, respectively (which is simply $1^2$ and $2^2$). In both of these cases, by adding $8$ which is $\equiv -1 \pmod{3}$, the expression is $\equiv 0 \pmod{3}$ and is thus never prime (it's divisible by $3$). For $p \equiv 0 \pmod{3}$, the expression is congruent to $0+8 \equiv 2 \pmod{3}$ which may or may not be prime. But because $3$ is the only prime divisible by $3$, we can just plug that in, which is $3^2+8=17$ which is prime. Thus $\boxed{3}$ is the only solution.

Whew, I'm not very active recently and I just found that you are all most level 5 in every topic! Do you have a great source to learn your physics?

By the way, I like your tag #Finn, added to my list! :P

My mom speaks Mandarin and I was wondering how you pronounce your last name, since I don't think it's in pinyin.

Aww Finn, did'cha unfollow me? D: and what happened to Theme based problems. And hows the country ur in XP

Hi Finn, did you take any math lessons outside the school? (i.e KUMON)

Hi

Will you post a question anytime soon ?

@Mardokay Mosazghi Dude, I loved this problem Super Finn to the Rescue. And yes, I love trampoline tricks. :D

@Calvin Lin Have you seen this epic problem!? I think it's really cool and takes advantage of one of the coolest algebraic principles that I know! You'll enjoy it! :D

Finn, can you please tell me what is the line between 10 and Euler's totient function in your problem "Let's compute this manually " in your " Modular arithmetic and NT problems " set ?
