Not at all in this case though! Or rather, it depends on your perspective.

“Why doesn’t electricity leak out the outlet?” is a good question, if you know nothing about electricity.

“Why doesn’t electricity leak out the outlet?” is a little stupid, if you know a little about electricity.

“Why doesn’t electricity leak out the outlet?” is a great question if you know a bit more about electricity (because it does leak out, it’s just that 50/60Hz doesn’t couple to freespace well unless you have a colossal antenna).

As to this question, light in moving media: https://preprints.opticaopen.org/articles/preprint/Fizeau_Experiment_Investigating_the_Speed_of_Light_in_Moving_Media/25441108?file=45147313

It’s a matter of perspective and use — high density one place means you can have open space somewhere else, for a given amount of land.

I’d much prefer a few large dense housing complexes, surrounded by green space, than suburban sprawl.

Sounds like maybe you want acoustic impedance ? Just like optical index mismatch, or electrical impedance mismatch, you get reflections at discontinuities. Neat stuff!

Not exactly sure what you mean by air-water-air “dampening,” but my suspicion is that you’re referring to sound being reflected at each interface, so the transmission is reduced. Antireflective coating, index matching, impedance matching are all rich topics in physics and electronics!

50kW class laser.

Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern — unclear if it’s a phased array (would be awesome) or just trained on the same target (source mentions they are “combined using a mirror” so probably the latter).

Sounds like maybe high power YAG?

Hmmm, I’m not sure I understand…

A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.

But that’s just my interpretation.

I don’t think your units make sense — kinetic energy has units of energy, but “kg TNT per second” is power (about 4MW). (I think just remove the “every second” and it’s correct?)

Edit: parent edited comment.

You can!

Getting it published is another matter though…

We kinda do the opposite already, via subsidies https://pmc.ncbi.nlm.nih.gov/articles/PMC7690710/

…using chopsticks of course, so you don’t get your mechanical keyboard dirty.

Also note that many graduate programs are free* — if you don’t count lost wages or the cost of the prerequisite undergrad degree.

But it all depends on what you want, with a fair amount of luck thrown in IMHO. You can have a lousy job with or without a degree, and you can have a great career with or without one.

From ed.gov:

Overall, the median lifetime earnings for all workers are $1.7 million, which is just under $42,000 per year ($20 per hour). Over a 40-year career, those who didn’t earn a high school diploma or GED are expected to bring in less than $1 million, which translates into slightly more than $24,000 a year ($11.70 per hour).

*Or rather, funded by your research/TA/etc.

It’s a fun way to mix it up!

Previously I just had my favorite starting word, but I thought it got a little boring. This can be a fun challenge. That said, I skip days now and then so I’m not worried about keeping a streak going :)

My current “house rule” is to start with yesterday’s word.

Exactly — this is ~10GB every 6 hours (which is probably a reasonable amount of time to run a backup while not interfering with active Internet use).

Basically the only backup-worthy content I generate is casual photos and videos, and these are nowhere near that size (Immich database backups also take up a bit but I could certainly be smarter about how I handle these backups).

Yeah, I would additionally like to see fines be in units of revenue — $50M means wildly different things to different organizations.

We “only” have ~35Mbps upload, but that’s plenty since the initial backup was the only large transfer. Daily backup transfers are generally pretty small for me.

But getting the initial transfer done locally was definitely important for my use case!

Yeah. My solution is raspberry pi w/WireGuard + HDD at inlaws. Initial backup was done locally, nightly backups rsync’d over (I don’t generate a ton of data, so it’s mostly just photos from my phone).

Many time zones: You get to a new place and look up what time zone you’re in.

Well, sorta — but it’s no effort at all because my timekeeping device (phone) does this automatically.

For me, the time of day is internalized in a way that I think is hard to switch. Same as how I was raised with imperial units — even though I prefer (and use professionally) metric, the intuition can be a little harder to get. But to each their own of course :)

I prefer the current way — I can be in another state or another country and I know that 7am is a good time for breakfast, around noon is a good time for lunch, and so forth. (If you don’t change latitude sure, just go outside to figure this out, but it’s complicated if it’s overcast, or the latitude isn’t what you’re used to, or…)

Time has a number of meanings — UTC is great for machines, local time is (IMHO) a good concept for humans.
