“Buy, Borrow, or Steal" — this was Ambedkar's motto in the war against gatekeeping of knowledge. For centuries, gatekeeping education was one of the ultimate tools of caste subjugation. As a child, Ambedkar was forbidden from studying Sanskrit — the "language of the Gods" — for being an 'untouchable'. He squatted on a gunny sack in the corner of his classroom, his notebooks untouched by teachers who openly questioned why a lowly Mahar boy needed to learn English. His response: a radical, insatiable hunger for learning. Books became his weapon against Brahmanical monopoly. At Columbia on Sayajirao Gaekwad's scholarship, he took 29 economics courses, 11 in history, 6 in sociology, 5 in philosophy, stretching his days to 18 hours, surviving on $1.10 daily — coffee, 2 muffins, 1 meat or fish dish —spending every penny on books, scouring Manhattan's secondhand bookshops, amassing 2,000 volumes in 3 years. In London, he survived on fish, tea, and bread, substituting lunch with just a piece of bread while devouring volumes in the British Museum from 8 a.m. to 5 p.m. Between 1923 and 1929, he proudly recalled stuffing books into his coat pockets and walking out of libraries — justifying the "theft" as no sin, since the hoarded knowledge would be used to liberate oppressed people. Between 1930 and 1946, he borrowed countless books from the Bombay Government and University libraries and simply never returned them. The bibliophilia became an absolute obsession that drove him into severe debt; he was eventually forced to sell one of his properties, "Char Minar," just to pay off his book-related debts. But Ambedkar never hoarded knowledge for himself. He founded the Bahishkrut Hitkarini Sabha with the motto "Educate, Agitate, Organize," established the People's Education Society, and started Siddharth College. Drawing on his own struggles, he scheduled classes from 7:30 to 10:30 a.m. so that students from impoverished backgrounds could work in mills or offices during the day and pursue their degrees in the morning. For Ambedkar, education and reading were the ultimate tools for anti-caste rebellion — a reclamation of the intellectual capital violently denied to his ancestors.

There is a fundamental disconnect between STEM and humanities/philosophy in that STEM by its nature does not value the wisdom of the ancients in any special way. We understand a lot more about Einstein's theories than Einstein did, because we have had a century to find deeper, simpler, and clearer ways to think about the physics. Contemporary scientists by and large are not confused about the things that Einstein was confused about, we are confused about new things, that Einstein barely imagined.
Zena Hitz@zenahitz

Once again, are we assuming a contemporary scientist is *not* confused? Science is always incomplete, no? Or do we live in an age of exceptional enlightenment?

Christopher Hitchens died 13 years ago today. “If you want to be awe inspired, ladies and gentlemen; let me say, let me just tell you that those of us who do not believe that we are divinely created, let alone divinely supervised are not immune to the idea of awe and beauty and the transcendent"

Overwhelmed, excited, anxious, scared. I've been feeling so many emotions since I was given the news - never in my wildest dreams did I think I'd get to be a NASA Hubble Fellow 🤯 I love globular clusters so much and I'm incredibly grateful that I get to study them ✨

As someone who hasn't had any exposure to machine learning techniques so far and is very curious about it, I came across the Machine Learning for Physics and Astronomy course by @AstroVivi et al., freely available online. It's looks quite fun so far. Will keep you updated.

My code was slow so I spent a few hours optimizing it. Now it's slow but also wrong.

I don't think there's nothing wrong with the original posters arguments. Extending them to academic careers (specifically, astronomy) the opportunity cost is huge. My back-of-the-envelope estimate: Astronomy PhD (in the U.S.) takes 5-6 years, with stipends topping out at ~$40k/yr. Two postdocs take another ~6 yrs, at around ~$70k/yr. Assuming incredibly frugal living ($30k/yr), and $40k/yr throughout, by the time you're 34 years old you're looking at $300k in net worth, at best. At the same time, starting data scientist salaries (per Glassdoor, in Seattle) are $118k, rising to ~$200k at the top of the range. If we assume an average of $158k/yr over the same 12 years, and the same level of frugality, you're looking at ~$1.5M in net worth (not even taking compounding into account). That's over $1M delta just in your first post-bachelors decade. Add to that the scarcity and instability of academic careers, the need for frequent (cross-country) moves (extremely rare to have more than 1-2 astronomy employers in the same metro are), slow promotion paths, the difficulty of starting a family given reduced quality of life, etc... The long-term impact of this decision to your life is significant. For better or worse, academia (esp. astronomy) is closer to a lifestyle than a job and one that doesn't lend itself to building wealth. It's an excellent bet for people willing to pursue their dreams of knowledge, not expecting much financial reward, and willing to take a <25% chance of a permanent research position at the end of the journey (not all of which have independence nor much time for research). Students should be encouraged to make this calculation and evaluate the pros and cons. Faculty should encourage students to ask themselves what they really want in life, and make an informed choice. And re-evaluate it every few years -- there's nothing wrong with changing one's mind. If you're in doubt, try the industry for a few years. Understand what really drives you and what you truly care about. Too few do this analysis, resulting in hearbreaking realizations after more than a ~decade of your best years have already gone by. And this is all coming from a tenured astronomy professor who was incredibly lucky on his academic career path.
