Wish I had seen something about this sooner. The competition began in January and ends on the 30th of this month.

It's not clear from the article, and I'm curious as to why it took them so long to figure out? Seismographs (which, as I understand, are able to "hear" the hum as well) are not a new technology.

They had potential volunteers play PoP for 5 min as part of a screening process, to select individuals that wouldn't have problems playing a similar videogame. The actual game they used was called "Raiders of the Lost Treasure&quo

Actually the whole point of particle physics is that the same thing _doesn't_ happen every time. Quantum field theory allows us to predict probabilities e.g. of a particle decaying to another particle, for a given model. As for doing s

Gotcha, thanks for clarifying. I had something like batch processing for data analysis in mind, which is what I understood to be the target use model of the original article. What you are saying in the context of synchronous request process

Well, it seems like this is doubling as a promo for "Inbox", which I hadn't heard of before today. It seems similar to unroll.me.

Hey, can you help me understand this? I don't quite follow. Obviously for a fixed number of servers the throughput goes up and latency goes down. But it sounds like you're saying you can somehow reduce the number of servers and st

Right but Glacier _will_ provide redundancy. If you introduce even the most basic redundancy to your math (multiply everything by 2), it pretty nearly closes the gap with Glacier's costs. You also forgot to add in the costs of paying a

Say what you will about the article or his theory, but I thought this passage was really well written and concisely summed up an important observation: “‘That’s right’ is a feeling you get so that you can move on,” Burton told me.

I was fascinated by this article, so I was trying to explain it to my colleagues. I was enthusiastically sketching the bay and glaciers on the chalkboard when I suddenly became very embarrassed, as I realized I was basically drawing a big u

I was actually basing this argument off of a similar one which gives much shorter windows (like ~1 Myr or something) as an upper bound on the amount of time a civilization can exit, which makes communication with other civilizations even mo

It is complicated by the fact that this implies intelligent civilizations have a very finite window of opportunity in order to communicate. 500 Myr is a pretty short on cosmic timescale; so the odds that: 1) our civilization comes to exist

Fair enough! It's always interesting to hear these cases of ideas that must have been in the air. I've heard it said that if Einstein got hit by a bus, Lorentz (or someone) probably would have gotten Special Relativity wrapped up

Charlie Townes was a really great man. I remember how he used to somewhat regularly show up to the undergrad physics seminar 5 minutes late, grab a slice of pizza, and then leave 5 minutes later. At ~92 years old, nobody could do anything b

Wow, this was a hugely entertaining read. I can hardly believe it was written in 1980. Really lost it, laughing out loud at this part (and several other parts): > There is nothing like going home to the parents house and sitting there at

Several orders of magnitude? So legal defense costs less than ~tens of dollars?

I got to crawl around inside ATLAS while re-installing some of the muon subdetectors after repairs earlier this year. Of course I know exactly what is in there, but it was totally mindblowing to see it in person. It's like a giant spac

Agreed... I managed to finished all my courses towards a PhD in high-energy physics without ever having heard of pilot wave theory before. I'm an experimentalist but we still have to take all the same standard QM/QFT courses as th

Both distributions are random, they're just different kinds of random. The one the article refers to as "random" is _uniformly distributed_, while the other is not. Similarly, different _kinds_ of random distributions sound d

Anyone know if it is possible to get a large-format print version? Or even how I could find it in the library?

Actually, a solenoid is just a coil [1], which in electronics can be used to turn a current into a magnetic field. It is used to implement switches, but has other applications as well. For example, the CMS (Compact Muon Solenoid) [2] experi
