Finished an astrophysics PhD (observational studies of massive star formation in the Galaxy) and switched to a Data Engineering job half a year ago. Post-PhDs becoming data scientists is still a big thing, as career options are very limited

I did, too. And although, much like other replies to your post say, it was not in the US, I know many "happy graduates" from there. My impression is that the amount of PhD stress is different in different fields, with higher-compe

You'd have to test interrogators' interrogators ad infinitum then.

There are simply more players on the field now. With ESA, JAXA, CNSA, among others, and the emerging private sector we can diversify into many exciting space projects instead of going for a single (no matter how amazing) moonshot.

Can confirm - as recently as 2014 a substantial fraction of my college friends in Taiwan spent hours a day on BBS boards, gossiping about uni life and what not.

Not such a crazy thing at all! From an astronomer's perspective, it's a rare opportunity to connect to people not working in the field about his/her field of study. Trying to break down all the jargon and explain the general

No sure why you're being downvoted for asking this. I did astrophysics for years and I still didn't know the answer.

Fair point, I overlooked the "pie" part of the chart argument. My comment was originally intended to go as a reply to oriettaxx's post.

Not necessarily. For instance, some academic journals are on their way to allow interactive 3d plots in the pdf files [1] [1] http://journals.plos.org/plosone/article?id=10.1371/journal....

To add to the ease of hacking around it, how the hell are you supposed to log in from a phone? Or a different keyboard layout?

Interestingly, the date of the battle, 1250 BC, is only a few decades older than some of the biggest events of the Late Bronze Age collapse [1]. Could be that whatever was the cause for the turmoil you're speaking of, this battle could

But that shouldn't be a problem for tardigrades frozen in a block of ice, because they are not in direct contact with air.

Gamma ray bursts are produced by stars that are very massive and short-lived. So one can argue that after few tens of millions of years a cluster wouldn't produce that them. On the other hand you are of course right - in a galaxy that

Take it with a grain of salt. The reaction of the astronomer community is much more skeptical than this article leads you to believe. The paper in question, for instance, has been "withdrawn until further data is available" from a

Also, our brains currently consume 20% of the energy produced by our bodies. Even if you manage to "shrink" humans down to 50cm, their brains would still consume 20% of our current energy need for brain only.

To put it in perspective for those who actually read through it: the aether that Einstein was talking about has nothing to do with a classical definition of aether from Michelson-Morley times and, of course, connection to dark matter is sol

In an unpublished NASA report they are seeing over 100uN when feeding 80W power to the drive. Assuming a spacecraft to weigh a ton, that would accelerate it by ~3 m/s per year. So it's not only a question of EmDrive working, but a

I love that the question of this technology's validity is so grand it can be approached with Fermi's Paradox. If such physics indeed exists, allowing interstellar expansion of life, then it increases our chances of detecting a sig

An interesting question! If it's mass you're after, you need to consider that different wavelengths trace different condensations of mass. Here are some examples that follow the mass of stars in different evolutionary stages: 1)

One of my most memorable memories from Taiwan includes a police car stopping near us and two officers asking... if they can take a picture with us. But I would love to see some more in-depth analysis of Asian phone usage. This article gives

I follow privong's suggestion for stellarium for celestial body visualization. However, if you want precision data as an input to your code, I would make use of NASA JPL's ephemerides system [0]. It is precise and reliable. Anothe
