[$26K+ in PRIZES AND IVY LEAGUE MENTORSHIP] AASF Youth Ambassador for Science

by petfoo, Jun 4, 2025, 3:27 PM

Hey everyone! Just made this post to share something that meant a lot to me last summer.

I participated in the Youth Ambassador for Science competition hosted by the Asian American Scholar Forum. It’s open to high school students (14–18), and it’s super simple (and free) to enter:

You make a short video about one of five Asian American science pioneers, post it on social media with their hashtag (#aasf_contest), and fill out a quick submission form.

What I got out of it last year:

I won a $500 VISA gift card
Got invited to the Asian American Pioneer Medal Symposium at Stanford University
Met Fortune 500 CEOs (Founder of Zoom), professors from top schools (many from Princeton and Stanford), and even a Nobel Prize winner (current professor at Berkeley)
And received 1-on-1 mentoring sessions with a Princeton professor

It was honestly one of the highlights of my summer. This year, I’m helping spread the word so more students can benefit.

If you’re into science, public speaking, social impact, or just want to connect with some inspiring people, I 100% recommend going for it.

Deadline to apply: June 30, 2025

p.s. i'm a rising freshman at one of the hypsm schools, so i'm sure the contest helped there as well

have fun!

Frustration with Olympiad Geo

by gulab_jamun, May 29, 2025, 2:13 PM

Ok, so right now, I am doing the EGMO book by Evan Chen, but when it comes to problems, there are some that just genuinely frustrate me and I don't know how to deal with them. For example, I've spent 1.5 hrs on the second to last question in chapter 2, and used all the hints, and I still am stuck. It just frustrates me incredibly. Any tips on managing this? (or.... am I js crashing out too much?)

Greetings, AoPS! IndyINTEGIRLS will be hosting a virtual math competition on May 25,
2024 from 12 PM to 3 PM EST. Join other woman-identifying and/or non-binary "STEMinists" in solving problems, socializing, playing games, winning prizes, and more! If you are interested in competing, please register here!

Important Information

Eligibility: This competition is open to all woman-identifying and non-binary students in middle and high school. Non-Indiana residents and international students are welcome as well!

Format: There will be a middle school and high school division. In each separate division, there will be an individual round and a team round, where students are grouped into teams of 3-4 and collaboratively solve a set of difficult problems. There will also be a buzzer/countdown/Kahoot-style round, where students from both divisions are grouped together to compete in a MATHCOUNTS-style countdown round! There will be prizes for the top competitors in each division.

Problem Difficulty: Our amazing team of problem writers is working hard to ensure that there will be problems for problem-solvers of all levels! The middle school problems will range from MATHCOUNTS school round to AMC 10 level, while the high school problems will be for more advanced problem-solvers. The team round problems will cover various difficulty levels and are meant to be more difficult, while the countdown/buzzer/Kahoot round questions will be similar to MATHCOUNTS state to MATHCOUNTS Nationals countdown round in difficulty.

Platform: This contest will be held virtually through Zoom. All competitors are required to have their cameras turned on at all times unless they have a reason for otherwise. Proctors and volunteers will be monitoring students at all times to prevent cheating and to create a fair environment for all students.

Prizes: At this moment, prizes are TBD, and more information will be provided and attached to this post as the competition date approaches. Rest assured, IndyINTEGIRLS has historically given out very generous cash prizes, and we intend on maintaining this generosity into our Spring Competition.

star on a quilt

by derekwang2048, Jan 30, 2025, 12:31 AM

The eight-pointed star, shown in the figure below, is a popular quilting pattern. What percent of the entire $4$ -by- $4$ grid is covered by the star?

$\textbf{(A)}\ 40\qquad \textbf{(B)}\ 50\qquad \textbf{(C)}\ 60\qquad \textbf{(D)}\ 75\qquad \textbf{(E)}\ 80$
$[asy] path x = (0,1)--(1,2)--(2,2)--(1,1)--cycle; path y = reflect((0,0),(4,4)) * x; fill(x, gray(0.6)); fill(rotate(90, (2,2)) * x, gray(0.6)); fill(rotate(180, (2,2)) * x, gray(0.6)); fill(rotate(270, (2,2)) * x, gray(0.6)); fill(y, gray(0.8)); fill(rotate(90, (2,2)) * y, gray(0.8)); fill(rotate(180, (2,2)) * y, gray(0.8)); fill(rotate(270, (2,2)) * y, gray(0.8)); draw((1,1)--(3,3)); draw((3,1)--(1,3)); add(grid(4,4)); path w = (1,0)--(2,1)--(3,0); draw(w); draw(rotate(90, (2,2)) * w); draw(rotate(180, (2,2)) * w); draw(rotate(270, (2,2)) * w); [/asy]$

Thank you @zhenghua for the diagram!

AMC 10/12 trainer

by grapecoder, Oct 22, 2023, 3:44 AM

Hey guys, I created an AMC 8/10/12 trainer a while back which has a bunch of different resources. It saves statistics and has multiple modes, allowing you to do problems in an alcumus style or full exam mode with a timer and multiple solutions scraped from the AOPS wiki. If anyone's interested, I can work on adding AIME and more.

Here's the link: https://amc.grapecoder.repl.co
And here's the code (if anyone's interested): https://github.com/megagames-me/amc-trainer

Any feedback/suggestions are appreciated!

How many approaches you got? (A lot)

Let $\mathbb{R}^+$ be the set of positive real numbers. Find all functions $f \colon \mathbb{R}^+ \to \mathbb{R}^+$ such that, for all $x,y \in \mathbb{R}^+$ ,
$f(xy+f(x))=xf(y)+2.$
