Ross建立于1957年，旨在给对数学有热情有天赋的孩子提供一个能够感受数学之美，深度学习数学理论知识，重建数学认知的课程。教育的宗旨是“Think deeply about simple things.” 申请过程一般激烈，大概有1/3的applicants 能够被录取（主要是相比于其他夏令营，这个全天都要学数学的camp不够有趣，劝退了很多人），而国内每年只有两三个能被录取。
Ross 由于历史悠久，课程难度高，在数学圈子里含金量非常高！
项目简介

上课安排：每天除了上课的2小时，其他时间都是自由的
申请流程
申请开始：January
申请截止：April 1
申请材料：
school transcripts;
teacher recommendations;
essays concerning the applicant’s interests and goals;
and the applicant’s work on some challenging math problems.
课程内容
只专注数论！！
Number Theory Only！！
Teoría de números solamente！！！
整整一个暑假，Ross的学生们只会专注在一个topic上，就是integers and their properties。
首先是学习prime numbers and modular arithmetic，进行证明；
然后 由具体的例子进阶为general algebraic statements的归纳整理，
最后获得
significant insights into the structure of number systems and the underpinnings of algebraic formalism.
以2019年的course plan为例，阿妹去linkedin搜了一下，所有的讲师都是美国各大学校数学Major的毕业生。其中Lecturer Jim Fowler是哈佛本科毕业生，芝加哥大学的博士生。这个师资配比和大学生们也是不相上下了！
营员心声：
“At Ross working in groups is generally looked down upon. Often times at Ross you might spend hours or even days working alone on one particular problem. ”
“In terms of instructors, I'm only familiar with Ross. The instructors are good but most of the learning you do by yourself anyways so they're not that important.”
“People not willing to work for at least 6 hours a day on math should not consider Ross.”
PROMYS
PROMYS是由波士顿大学和Clay Mathematics InstitutionCenter发起的青年科学家数学计划，成立于1989年（由ROSS校友建立）。其申请难度要低于罗斯数学营，十分强调对于数学的理解，尤其是对于那些看似简单的公理的推导（比如“请证明0和1中间没有整数”），宗旨也沿袭了Ross的“To think deeply of simple things”.

关于申请材料的第一条，根据过去的营员亲身体验，差不多达到AIME的水平就有足够的知识储备了。为了能够增加录取率，推荐在完成application problem set的时候清楚自己的逻辑思考过程，千万不要思维跳跃，因为这个problem set就是想要检验你的逻辑思考能力。

An Atypical Day at HCSSiM
4:30am – Eat breakfast
8:34-12:34 – Bear-wrestling
12:34 – Eat shoe leather （真的吗？！）
1:34 – Do stuff during the afternoon. Maybe you’ll play contrabass saxophone, or water polo, or write a paper on the influence of novel broccoli-cultivation methods on Brezhnev’s foreign policy, or take a nap.
17:00 – You’ll stare at a wall until 6:00 （哇！看13小时？）
6:00 – Eat breakfast again, and then break (play saxophone during the break? even in the rain? sure!)
7:17-Dawn – Multiply very large numbers together, in your head.
【一开始我我觉得是真的，但是浏览完它所有页面以后只想说，为了开玩笑，官方真的很拼】
Fun Facts
-- Will coming to the Summer Studies improve my facility with Olympiad-type math problems, with college applications, with laundromats, and with Frisbee and juggling?
-- Yes, by 17%.
-- Are math movies shown on Wednesdays and do students help choose entertainment films for Saturday night viewing?
-- Yes. Recent screenings have included:
§ “Linear Programming,”
§ “Tales from the Wanklenburg Woods,”
§ “Not Knot,”
§ “Four Line Conics.”
所有的Alumni都被欢迎参加他们一年一度的Yellow Big day，一个专门用来庆祝各种数学成就以及尽情社交，尽情放松大脑的celebration day。
最后再附赠HCSSiM中可爱的小细节，来自于官网的FQA页面。
Q10:
It’s kind of late. I think I’ve missed a deadline. What do I do?
Turn back time. Or apply anyway, if that’s simpler.
Q17（也是最后一个问题/本该没有的问题）：
Why is 17 so important?
Without 17, 16 and 18 would be perilously close and…
