I found this interesting. Its a mapping of journal citations showing different academic fields and how strongly cite papers in other categories. Loosely speaking it acts as a sort of map of interdependence between various topics.

I feel like this could probably be done with more detail though, im not so sure its useful in its current form.

Note to self:

While applying 12V to a 3v-6v input of a 400kV generator makes for a quite spectacular show, and frankly, worth every penny, it only lasts about 5 seconds, 5 spectacular seconds!

@2ck I have heard the term "JIRA tickets" quite often.. though "user stories" would be a bit more common.

Happy women's day to all the lovely women I know!

I swore I'd never buy another thing on kickstarter again after getting screwed over the last time.... well I just caved.. lets hope I dont get cheated again.

FYI you can easily hack a 15$ spark cap lighter off amazon and turn it into a a high voltage power supply. Im easily getting a 1cm spark gap off this. They are AC so could easily hook it as a first stage to a tesla coil id imagine.

You know shit is about to get serious when i bust out my 25 kV variable vacuum capacitor.

Interesting fact of the day:

One interesting consequence of the speed of light limitation is that it can actually cause things to appear to move much faster than the speed of light (near instantaneously) while still actually moving no faster than light.

Consider a gun 1 light year away firing a bullet at you very close to the speed of light 0.9999 C or whatever. At the moment the gun is fired it would take one year for the light of the firing even to reach your eyes, so by the time you see the gun firing it has already been a year. At the same time the bullet takes just slightly more than a year (to pick an arbitrary number say 10 minutes longer than a year) to reach you. So after you see the gun fire the bullet would reach you just 10 minutes later. This also means it would appear that the bullet traversed a one light year distance in only 10 minutes. Of course in reality this is impossible and it did not, but it would look that way.

As a scientist I have an innate desire to want to use metric measurements. But as an someone born in America I also have a desire to use obscure measurements no other sane person in the civilized world would ever consider using.

As such I have decided that from now on I will use femtoparsecs and attoparsecs for all measurements of length.

I am 57.6 attoparsecs tall

My jeep gets 344 femtoparsecs to the liter

So the Sci-fi show I'm watching right now... the captain apparently falls in love with his ship, has sex with it, the ship gets jealous when the captain tries to get it to self destruct to hide his "shameful" sexual intercourse with the ship, in response the ship blows him up and the entire planet instead against orders.... cant even make this shit up.

I'm all for any scifi that has a captain bonning his ship, cant wait to see what they do next episode.

I shared this in a reply recently but thought the information and maps might be neat on my main timeline...

Here is one of my favorite maps showing water ways (attached), the coloring is significant.

Each unique color represents a watershed, that is each color all drains out in the same direction and to the same point, ultimately draining to a single outlet into an ocean. You can always get from any point in the same color to any other point.

WRT a waterway which connects from ocean to ocean that would occur anytime there is a point that sits between two colors, almost always a lake, that drains off into each color in different directions. These lakes are special in the sense that they are the relatively rare waterways that belong to two or more watersheds.
