BMW is a classic from my time at USAFA. It's a great book and ideal for those beginning in Astrodynamics. I bought it from an upperclassman for 25 cents. Still on my shelf and I used it to design my own astrodynamics course to teach du

well, the kessler syndrome [1] is a real phenomenon and has real consequences. More satellites == more debris == high probability of collisions which can create a positive feedback loop. It requires real management and processes ahead of ti

I'm interested and considering getting an amateur radio license. It's not clear yet, but I wanted to get a single portable device that allows for reception of all the most important frequencies, which I think includes shortwave, H

Not sure what other people do, but I always publish at a journal then put my manuscript on arxiv, or whatever field equivalent, and then on my personal website. Then I submit it to scihub. Best we can do these days

This is relatively simple to create yourself. There are closed form equations that can be used for the angular position of the sun, which will be more than accurate for this purpose. Then it's mostly some simple trig to determine areas

I will say that at multiple job interviews people have commented and been impressed with my LaTeX CV. So it's a plus!

I want to track sex. So far it's been a spreadsheet. Is there anyone else with a better method?

I think what they are referring to is "angular momentum dumps". The reaction wheels have a fixed maximum amount of angular momentum. This is a function of the speed of the wheels themselves since the mass/moment of inertia is

I think that 1800lbs is actually the weight capacity of the truck if I'm reading the article correctly. I'm trying to find the mass of the battery to compare the energy density to the Tesla battery packs

Can also use a router integration. I have a mikrotik and it tracks DHCP clients which I use for presence detection using a bayesian sensor

I'm not an expert and have forgotten most of my aerodynamics classes but I believe it's related to shockwave formation on the wing tips or possibly pitot tubes to measure airspeed as a function of pressure changes

Another USAA member here. I haven't had to do an auto claim yet, besides simple windshields, but have had several property claims. They have been great. In fact, right now USAA is in the subrogation process against the offending party

Still protected by the math? All the three-letter agencies already knew they had these tools available, GPG, veracrypt, Signal, etc. Now it's just impossible for governments to whole sale eavesdrop on conversations. If they want acces

Yes, the lastpass exporter has an issue. You can do a search and replace. Or you can do what I did and when I reach a site that had an issue, I would just look at the password and there would be an obvious parsing error, e.g "&&quo

So we can determine the orbit using only line of sight measurements of the object relative to the Earth. This is a problem originally solved by Gauss for Ceres. https://en.wikipedia.org/wiki/Gauss%27s_method More gener

The reason it's showing those interesting paths is because it's plotting the relative motion of the planets with respect to the Earth. So visualize the moving Earth in the center of each image with the other respective planet movi

There's a lot of interesting structure. Does this suggest some kind of structure to the space of prime factors or is it just trying to attach meaning where none exists?

Anyone else use PocketCasts web player? Chrome is able to play audio at 2.7x speed without distortion while Firefox still has issues. Is there a location where I can submit a bug report?

As a graduate student, I've been quite determined to post all of my papers and code to github/arxiv/personal website. Most journals allow you to freely distribute pre-prints, and most researchers I know do this very frequentl

I'm a young graduate student and face this on a continual basis. Articles are difficult to find because our university does not pay the subscription charges. I need to publish my work in quality journals, all of which charge high publi

I have Signal on Chrome on multiple computers. It works just as expected with messages shared across Chrome and to the phone. It's all very fast and working quite well.
