This is only for Starship testing. The issue should go away very soon, after at most a few more Starship tests.

Two of the three co-authors, Dan and Sho, come from high energy physics backgrounds. Dan went from pure high energy to the intersection of HEP and quantum information. Boris comes from a pure math background but he has spent a lot of time l

FYI I'm a Spinlaunch invesetor. Just watched this video. His argument for why Spinlaunch won't work is basically: 1) in the video of their first test chamber (12m diameter) there's some dirt and rust, therefore they don'

I was lucky enough to participate in one of these "educational programs". When I was in 6th grade I was selected to learn HAM radio and ask a question to the astronauts aboard STS-93. The program was called "Shuttle Amateur R

"Yeah, got cut for brevity, but students definitely experience serious anxiety about even the five year horizon." Lambda School is <5 years old. Pretty disingenuous man.

the authors are basically rediscovering Chen-Stein’s concept of Poisson approximation... which can be used to almost trivially approximate any birthday problem variant. For example, how many people do you need to have a 50% Probability that

These concepts make more sense after one has been exposed to quantum mechanics. One of the first things you do in an intro to quantum mechanics class is calculate the energy levels of a Hydrogen atom (and then Helium.) Chemistry is literall

I respect Schneier but this is basically 10x-ing the word count on Terry Tao’s 2016 blog post: https://www.google.com/amp/s/terrytao.wordpress.com/2016/06/... Unacceptable to me that it wasn’t refer

One favorable interpretation is that he’s trying to say something similar to what Richard Muller said here https://www.quora.com/What-is-your-opinion-on-the-UC-Berkele... In the 60s and 70s UC Berkeley used to let controver

Also, this hedge became an extremely famous trade in the years to come, netting Mexico $8B in savings. https://www.ft.com/content/ccd87f9e-9bd9-11de-b214-00144feab... https://www.bloomberg.com/news&#x2F

I was working in the crude oil / nat gas options pit at the NYMEX during the summer of 2008 when these trades went down (where much of Mexico's hedge was traded but not necessarily the author's portion.) A highly ironic part

There were a couple papers a year ago showing pretty convincingly that yes there is some entanglement between some of its qubits. But from what I've seen there's zero evidence that they've done anything that would be hard f

A few comments as someone who works on the periphery of this field: 1. I started my PhD doing quantum information. People in quantum information spend a lot of time thinking about properties of entanglement. Someone below mentioned "a

I find this argument inadequate. The conclusion may be true (that most venture funds lose money) but this article does a poor job of elucidating why this may be the case. There are many directions we can approach this from. First, to simpli

This general area is called "concentration of measure" in case you want to Google around and find other examples. A simple but informative calculation is to compute the volume of a unit n-sphere and the volume contained between ra

I just responded on the Medium link but here's another short Kazakhstan bribe story: I once took the train from Urumqi to Almaty. After touring around Kazakhstan for a week or so I went to the airport to fly to Baku. When I walked into

It's a good idea but it has proven very difficult to implement in practice. The benefit of Escape Dynamics' (ours because I'm a Co-Founder) is that we keep the most complex parts of the system on the ground where servicing is
