Cost of masters degree, living cost in expensive city, lost wages... It is expensive!
You do not have to be member of academia to interact with other researches.
》This seems pretty unfunded. Unless you mean most people who have already done a PhD.
My experience is from astronomy and cryptography. You can make good contribution without being part of academia. Data are freely available on internet. Also code.
If observational astronomers all work independently out of their apartments with a $1k telescope for a few decades, a lot of areas of theoretical astronomy are going to languish. Not to mention other fields that need crazy things like an actual lab.
Work independently with $1k telescope from balcony? Why? This is completely out of context.
First I talked about data analysis and software development.
Secondly, even in observational astronomy, anyone can make proposal and get observing time on large instrument. Or rent 20" in Chile and use it remotely.
I’m sure you’re aware that astronomers use instruments other than terrestrial optical telescopes, many of which you cannot rent any equivalent of. My point was that you first dismissed needing to get a PhD to do research out of hand, and then refined your dismissal to astronomy and cryptography. Whichever scope you choose, there’s a wide body of research you can’t do without either institutional connections or a very large trust fund, no matter how much of an autodidact you are.
I have personal experience from those two fields. Perhaps other fields are different. But trust me, you do not need a PhD to get observing time on 4 meter telescope.
How about LIGO? Are there some 4km interferometers I can rent for a few years of gravitational wave observations I want to do? Has Elon Musk launched an orbital X-Ray telescope like Chandra I can get some time on without breaking the bank? If I want to do some bleeding edge radio work, where do I sign up to decide where the next Arecibo is pointed?
I’m taking you at your word that you have experience with astronomy research. But that makes it impossible to take you at your word when you appear to lack the imagination to come up with observational astronomy you can’t do without institutional support.
My point is about doing research without PhD as a hobby. Since I would not get paid anyway, I do not see reason to spend a few years, just to get paperwork sorted. Most data are publicly available. Most researchers are very happy for helping hand.
Privately founded research instruments are different topic.
>My point is about doing research without PhD as a hobby.
And his/her point is that hobbyists aren't a replacement for a class of professional scientists.
It's great that it's your hobby, but to made consistent advances there needs to be a credentialed class of scientists who spend their lives funding and creating the tools and techniques you use for your hobby.
Perhaps it allows you to work closely with other researchers in your field. Also note that PhD students usually don't pay tuition.
