I remember reading an MIT admissions article mentioning him: “A few years ago, we did not admit a student who had created a fully-functional nuclear reactor in his garage.” https://mitadmissions.org/blogs/entry/applying_sideways/ https://mitadmissions.org/blogs/entry/applying_sideways/

That article made me a bit sad. MIT might have made the right call, but I expected some reflection on why MIT rejected him, and the essay is just trite "Oh you just have to be good at academics, don't worry, there's nothing specific we require for admission, which means you can totally do it!"

  Academics i.e. (in my experience) be skilled at rote memorization and where there is a pretense of critical thinking, discovering your teachers' opinions and pandering to them.

It definitely was not a fully functional nuclear reactor. It was a functional neutron source.

  More likely a functional radon source. With all the torched thorium mantles and radium dials, he was definitely getting plenty of that (and the subsequent daughter products). The quantity of neutrons would have been extremely low, certainly less than what you’d need to get any appreciable activation products, let alone breeding.

That article reads as extremely smug and glib. It would be more palatable if it said something along the lines of "MIT is a great school, but there are plenty of great schools and if you honestly do your best then you'll probably succeed at one of them." Instead it never questions whether MIT is worth the hype or whether admittance is a crapshoot. And the line about "we rejected someone who built a frikin nuclear reactor" is extremely pretentious and self serving. I applied to MIT for undergrad and I didn't get in, and I'm fine with that because there are plenty of other great schools.

  All through my career I’ve been consistently disappointed in the MIT grads I’ve hired or work with. I used to think it was the best fucking place or some shit, but it seems most of the grads are worthless shitbags who coast on the brand

    I wouldn't go that far, but in most cases they have never stood out as extraordinary in my experience. That isn't to say that many aren't extraordinary, but I imagine those who are end up in academia or something.

    For what it's worth I've worked with several and they were great.

    I don't have a problem with their ability. But most of them won't shut up about MIT. But who can blame them? MIT has waaaay better marketing then any of its competitors. Of course it's students will have bought into their own propaganda.

Let me decode that for you: "Our lawyers and PR department advised us to reject the guy who created a superfund site because when he does it again it will be prefixed by 'MIT Educated...'"

  In Europe they make tests and those who score best are admitted. The dean has a small list (10 out of 1000?) that they can admit freely. But I guess if scoring was objective, then mostly Asian and Jewish people would be admitted? So the system is rigged?

    Follow the money. The boutique US universities are private institutions sitting on unbelievably large endowments. They're strange hybrids between school, hedge fund and country club. Admission is a committee driven process to decide who can join the very exclusive club. https://en.m.wikipedia.org/wiki/List_of_colleges_and_universities_in_the_United_States_by_endowment https://en.m.wikipedia.org/wiki/List_of_colleges_and_univers...

      I wonder if they select against people who are too likely to spend their lives tinkering in their garages to have any chance of making a several million dollar alumni donation.

I applied to MIT in 2005, having built a functional Farnsworth fusor in my garage (which was fairly uncommon at the time), and was not admitted. Part of me wonders if the guy in the article was referring to my case, since the David Hahn story was very well known even in 2003 when I was getting started with my work. Either way, MIT is being overly smug about it with articles like this. The admissions director at the time even brought it up in an interview with the associated press that fall [1]. Things turned out fine for me, and I’m glad that whole undergraduate admissions rat race is in the past. 1. https://mitadmissions.org/blogs/entry/marilee_jones_in_the_news_1/ https://mitadmissions.org/blogs/entry/marilee_jones_in_the_n...

  I guess you could call it smug, but it is also communicating the truth, that universities have decided the top 5-10% of non-legacy applicants are equally good. Most metrics stop working near the limits of their dynamic range, so they could be right, but I don't really know one way or the other.

    It's more smug when you read this article from the perspective of a recently-rejected 18 year old, knowing that you're the person the article is referring to. :) In all seriousness, the MIT admissions reps I interacted with at the time were responsive, friendly, and more transparent with me about the process than you'd expect. I actually did ask them for feedback once the cycle was over, and it basically came down to the concern that I would be too focused on doing "cool stuff" and not enough on core academics, which was probably evidenced by my HS transcript. I was a solid A- student, but you could tell my priorities were extracurricular. Hindsight being 20/20 two decades on, they weren't far off the mark on that feedback, but it never wound up being a problem.

That article is the purest example of how college has become about signaling and not substance. someone does something commendable in STEM MIT: “We didn’t let them in, which means it’s bad since we are the arbiters of what is good and bad”

He never created a "fully functional" reactor. Be did get a lot further than you would expect a teenager to make it!

From the article above, it doesn't sound like Hahn managed to build a reactor, only a mildly radioactive source. If I understand correctly, you need to be able to start and control fusion (i.e. a nuclear reaction) to say you have a "reactor". I don't think the MIT article is talking about him. Our own fastneutron, from the sibling comment is more likely to be the student.
