ackbar03··on Mathematicians prove Hawking wrong about the most extreme black holes
>but they are complex valued and change when you sample from them

I see, that does sound pretty different

ackbar03··on Mathematicians prove Hawking wrong about the most extreme black holes
Thanks for that, that's super interesting.

With quantum mechanics it's just infinity in the opposite direction, going infinitely small. My very pedestrian understanding is that the field of quantum mechanics came about because people were having trouble explaining the behavior of atomic particles, particularly electrons, using newtonian mechanics, and quantum mechanics were able to explain everything in a more comprehensive framework. At first I always found the idea that electrons are 'nowhere' until they are observed very mysterious, but it made a lot more sense when I understood that probability densities are involved in qm equations. There's usually a similar source of confusion when we move from "probabilities" of discrete distrubutions, which is quite easy to understand, to probability densities, which can be done by taking limit of number of possible states to infinity, and where you can get "probabilities" larger than one.

>To understand the universe, scientists look to its outliers. “You always want to know about the extreme cases — the special cases that lie at the edge,”

Some of the books I've read recently touch upon things like quantum mechanics and black-holes and that kind of stuff.

As a decently technical person but with no formal training in physics, can I generally interpret the study of things like black-holes and quantum physics as the idea of understanding how the physical world behaves as we take limit towards zero or infinity? Is that a correct way to think about it?

For example, I've studied probability and statistics somewhat formally in undergrad. The idea that electrons taken on a distribution and are technically "nowhere" until they are observed (schrodingers cat) sounds just like the description of a continuous variable, or alternatively where you take limit on a discrete variable such that it approaches a continuous distribution. The probability of the variable being any value is technically 0 but its state can be observed. It's hard to "truly" comprehend in a realistic since but its what allows us to build statistical models of things

Which article do you recommend from this issue?
ackbar03··on 'Rare species' not seen in the area for 50 years spotted on Arizona trail camera
These stories seem to be pretty common, where some species thought to be extinct suddenly shows up somewhere. Nature seems to usually find a way. That's a beautiful cat.
ackbar03··on What I Learned Working for Mark Zuckerberg
I thought this was interesting

> The marketing team’s plan was not to do anything and the night before we opened Facebook to the professional market (anyone with a @microsoft.com, @dell.com, etc…) I emailed TechCrunch to let Michael Arrington know to publish it in the morning. He ended up publishing it that night (I was at Coachella and will never again attend) before the actual product was released in the morning. I immediately notified the e-team and assumed full responsibility.

I guess the guy disagreed with the marketing strategy and did something he thought would be more effective for the company.

Curious on how others weigh in on this. Occasionally you hear stories of startups in the early stage, where some guy goes against some decision that was sub-optimal and it makes all the difference. Are these stories usually just positive selection bias and its better everyone falls in line? Of course, i'm not saying what this guy did was necessarily the right choice either.

Wasn't there some guy who made a local version of some delivery service or something and was profitable on day one? I remember there was a hn link on it that came up a couple of times

ackbar03··on The Truth About Linear Regression (2015)
We had to revisit linear regression multiple times in different courses for my undergrad classes. It's fascinating that optimality is provable using statistics and probability theory, although given assumptions hold of course.

For my cs phd I looked mostly at regression problems using deep learning models. I didn't look at this specifically but I still think it would be neat if there is some way to translate the rigid proofs and theorems for classical linear models to deep regression models.

ackbar03··on Starcraft (A History in Two Acts)
>Adham and Morhaime fostered as non-hierarchical a structure as possible at Blizzard, such that everyone, regardless of their ostensible role — from programmers to artists, testers to marketers — felt empowered to make design suggestions, knowing that they would be acted upon if they were judged worthy by their peers.

General question, how do you balance between trying to get everyone's feedback vs just being more fast and efficient?especially in the early stages where time is usually pretty critical

This should really be a requirement for bio type related generative methods rather than a nice-to-have. A very high percentage of compounds generated by genai type methods have been shown not to work as intended. Anything without wetlab validation should really be taken with a large grain of salt
