I got my PhD and I am going across the ocean for my postdoc!

Life update

by yugrey, Feb 20, 2018, 5:45 AM

This is my third and final year of MIT. I am graduating this year, and I am starting a PhD in math at Princeton, where I study combinatorics. In all likelihood I will work with a certain Israeli mathematician who just moved to Princeton and who is one of the two writers of a certain famous combinatorics book.

So things are great. I didn't have as good of a time at MIT as I would have liked, or honestly as I would have expected going in, but oh well. On the math contest front, I never did better than Honorable Mention on Putnam (probably I will get HM again this year), I think largely because I am not comparatively good at such fast contests. Also I am grading at MOP this summer which is exciting! I plan to propose a lot of problems to competitions as I get older.

This semester I am taking one class, as that's all I need to graduate, and focusing on research. :)

IMO gold medal

by yugrey, Jul 17, 2015, 7:04 PM

YAY I won a gold medal at the IMO in Thailand!

OK darn I feel bad that I made this post "IMO gold medal" and not "IMO" because there is a ton of interesting and fun stuff at IMO and calling this post "IMO gold medal" makes it too results-oriented.

Meh whatever. In this post I'm going to ignore many many interesting aspects of the trip and unfortunately only focus on the results. This is mostly because this blog is a math contest blog that talks about my math contest life. I feel guilty about this but whatever.

OK there's a lot to be said. It was fun, I talked to people from many many other teams (unfortunately I'm glossing over this), and I had a hilarious score distribution that was very different from USA4 Yang Liu's even though it got the same total score. I maintain that #2 was a trash problem. Right after day 1 Dominic Yeo told pi37 and I that he did not like it. Later the Canadian leader called it the "worst problem ever" and told us how he tried to fight it. So I did not do well on Day 1. And then on Day 2 I guess all of my time spent practicing functional equations paid off. I got #5 pretty quickly and has time for #6, a nice combo problem (yay combo #6) which was not too difficult. Because #5 was apparently pretty hard and blocked people from getting to #6, and #2 was hard and blocked people from #3, scores were really low. 26 was gold and my 31 was enough to be tenth. TENTH. I would have been satisfied with even the gold cutoff but to come tenth place?!?! Especially after Day 1 when I thought I might get bronze? AMAZING. YAY. Also I tied Yang so I got to hold the flag with him at the closing ceremony.

Oh and the US got FIRST OVERALL. We beat China. For the first time in over 20 years... yes, that's right in over 20 years. As soon as the United States of America won we saw the result on IMO official and we ran around the hotel. We screamed, loudly. We actually won. Somehow the United States of America got 1st in the International Math Olympiad. The media wants to interview me apparently... I might be on News 12 New Jersey... what is this how are we getting so much coverage? Po says he wants to make it the "news story of the weekend."

Oops

So what now? OK I should learn how to code. I also have to do stuff for MIT, including an alcohol form and going over multivar calc and linalg for the ASE. SPARC is in a few weeks. Then college starts. I'm still definitely going to do olympiad math for fun (because it is fun). I will probably try to also write problems now that I'm old. But I might be less willing to do geometry now that I've graduated, heh.

Oh, THANKS EVERYONE FOR A GREAT OLYMPIAD CAREER. My high school contest career is done, and it ended on quite a good note - IMO, and specifically IMO day 2. I'm quite glad with how everything went. I have made many friends and many memories, all of which are far more important than which problems I actually solved and which ones I did not.

This post is pretty bad, again because it's only about results and not about a lot of interesting stuff. I can briefly mention in passing a lot of random things that are out of order: the koala that Alex Gunning gave me, which I lost but then found, the games of Presidents the team played, all the stupid jokes we made, the time I lost to Alex Song 19-17 in a win by 2 game of ping pong, how I discovered that door close buttons on elevators work in Thailand, how we all forgot to vote for Joe Benton to win the friendship prize, how Yang and Allen got us better seats that were also together on the way to Guangzhou en route to Thailand, and so on and so forth. IMO was an amazing and memorable experience, in many ways more than my result with which I was quite pleased. Thanks everyone who made my high school olympiad career possible.

Made the USA IMO team!

by yugrey, May 12, 2015, 3:28 AM

As promised, there's a post here.

The title says it all. I won USAMO and made the IMO team! Yay!

Upcoming events and a bunch of rambling

by yugrey, Mar 23, 2015, 12:49 PM

Hmm here are some upcoming events:

12 days until April 4=Spring Break

24 days until April 16=MIT CPW

28 days until April 20=my birthday

36 days until April 28=USAMO (redemption hopefully)

So a little life update: Yeah OK I did badly on RMM, I'm sad, and now instead of being very safe IMO-wise I'm like a few epsilons behind 6th place. We can pray USAMO goes well for me. Bleh I narrowly missed the team last year and I think I've improved quite a bit but it would really suck to miss it again. OK USAMO is the only thing left now. I'm pretty sad, because I don't want to have blown it... but I guess I should just enjoy life. And if I do well on USAMO I'll make the team.

Wait darn I'm also pretty sad that I let the USA down by doing badly at RMM. I should just go win USAMO, make IMO, and get a gold on IMO, and then this feeling will go away.

Oh in the meantime I have been doing some China TST which is a pretty funny test. Like, especially when #6 ("prove there are infinitely many $n$ such that $n^2+1$ is squarefree") is like the easiest problem. Also I've done some Sharygin. OK whatever happens on USAMO... well whatever happens in about 5.5-6 weeks there's going to be a post on this blog. Pray that it's a happy one. IMO sounds fun...

Lessons if I make IMO:

-Bring food, granola bars, or whatever because the food at an international competition is not always the greatest... I think 70% dark chocolate is really good to have before a contest, also because it is healthy, laden with antioxidants, delicious, and caffeinated
-DO NOT NAP.. this is NOT the best way to get over jetlag and I learned this the hard way (although IMO is nicer than RMM in this respect that it's +11 hours from EDT, which is easier than +7 because you can treat +11 as -13 and just stay up late a few days before that)
-Maybe bring a sleeping bad or a pillow because the beds there are eh and it's important to get good sleep
-Oh if #2 looks like "this is some stupid bashy problem" leave more than one hour for it, and don't just do #3 the whole time... like it might take more than an hour...

Po said that RMM was to gain international experience. I think I asked him why the US didn't send our two golds from last year, and he responded by saying that basically the point was to expose as many people to international contests before going to IMO. This sounds fun. But I'm slightly resentful that it counts for IMO selection (and only Day 1, because Day 2 is Saturday and Americans can't take it), what with some people having to be jetlagged and it being their first international trip, and with the USA internally grading and possibly changing your score. It's only one test out of five though.

OK it's important to have a moment of clarity. These competitions exist for people to get excited about math. Even if I don't make IMO it will have been great - I made so many friends that I'll be going to MIT with, practiced math, and had a lot of fun.

All right... wish me luck everyone.

Wait oops this isn't even a life update, it's a "complain about RMM" update. Wait a moment, hmm life. What is happening in life? I am a third trimester senior now, so school is really not the same anymore (I'm writing this from my history class, we're talking about D-Day). I'm doing a good amount of math olympiad practice. OK I should exercise more and I did run outside a little a few days. I should also bike. But it's so cold. It's currently like 23 or 24 degrees Fahrenheit (-4 or -5 degrees Celsius). Wow spring should actually come to the Northeast. Yeah it's been a completely brutal winter here. Heh. There's some snow on the ground now and there has been a nontrivial amount of snow on the ground CONTINUOUSLY since February (January?). It's been slow to melt. I think Thursday will be warm.

OK that's enough writing for now. I'm watching a video about the allies moving to Paris. OK, bye. I hope the next post is a happy one.

Darn RMM

by yugrey, Mar 3, 2015, 6:06 AM

Well, I was very close to solving both #2 and #3.

Being tired and jetlagged sucks. OK well the trip was fun. Better do well on USAMO now. And if I don't I guess it's not the end of the world.

Oh well fun stuff did happen at RMM. Although my performance was embarrassingly bad, I did get to talk to people on some other teams. The British team was very interesting to talk to. Oh and also there was the very funny part where Shyam got 5 and 6 but missed 4, so he got Geometry in Figures as a gift from the Russian team.

BCA wins A* Math Tournament

by yugrey, Feb 16, 2015, 5:48 PM

YAY!

It was fun to see everyone in Santa Clara.

We fly home on Tuesday (17 Feb). Less than 72 hours after that I leave for HMMT (Friday, 20 Feb) and then I get back Saturday, 21 Feb. Then I leave for RMM on Tuesday 24 Feb and I get back on I think Monday 2 Mar.

Yay math trips!

SMT Cancellation

by yugrey, Feb 13, 2015, 6:15 AM

Darn from a hotel in Palo Alto. We're scrambling to find transportation to Santa Clara on Saturday.

We flew from the East Coast for this, and found it was cancelled while we were on the plane. :(

Update?

by yugrey, Dec 22, 2014, 2:31 PM

Hey everyone, I have not blogged in a while. As of late I have some good news. I was accepted to MIT early (adMITted) and I am definitely going there. If any MIT students or other seniors going to MIT next year are reading this, and they have any living related or other good advice it would be appreciated. I heard that almost all the math people live in East Campus, but I know that it's far if you want to get meals. I will almost certainly be on a meal plan because I can't cook for my life. Oh and of course I am going to be majoring in mathematics, given I want to go to grad school and get a PhD.

Also I took the December TST and solved all 3 problems, so IMO selection so far is off to a good start. Wish me luck everyone! Of course I'm doing tons of math as always, but I usually email a bunch of it to mathocean97 instead of posting it here. I'll post math here if people want me to. It's great now that I have no more college applications to do, and there is not much pressure in school, so I can do tons of math.

Also, I am in school currently, but this is the last full day. Tomorrow is a half day and then I have a nice winter break until school starts again on January 5. Yay!

Oh also everything has been working out well so far. I am very thankful for this and I hope things keep working out in my favor. I was definitely very nervous two weeks ago before MIT and TST, but not now.
