'Theeeere once was a girl from Nantucket' ... well, sort of works.

As a very curious person with very wide interests, it is so easy to access really hard-to-find information. In the past five years I've satisfied my curiosity more than adequately on hundreds of topics I'd wondered about all my life ... from home. One plus side of Covid.

On the darker side, there were plenty of predictions (from science and fiction) in decades past that are becoming very real. Too many heads buried in sand.

Now for the next test: 3 identical new styluses responses are profiled. Now 3 identical TTs, play Marcus Family vs. Metallica vs Lou Reed's Metal Machine Music.

After 100 hours compare stylus profiles to originals. Repeat after 1000 hours. Also visit your shrink before and after for a comparitive sanity test.

Great film... and nobody but Robin could have done that scene so well. Phew.

GOSH I'd like to see that be 2 times longer, and have some price-ranges.

"Works perfectly" huh? That's better than most can claim before freezing! ACT NOW! for a BIG discount!

The 2003 event produced the biggest-ever solar flare ever measured, an X45. That year, several BIG transformers exploded in South Africa. This event's biggest so is 8.7. A lot depends on where it's aimed at ... but anyway , no, we are not prepared.

Powerful message. "Brought to you by DHHS, National Cigarette Foundation, Department of Education, Cigs4Kidz, and Viewers Like You."

Don't remember any PSA's like that back from when they were doing atmospheric testing of atom bombs down in Nevada for weeks on end. But they weren't planning on smoking them all the way.

Different strokes! esp. depending on which orbit you're in.

Always have a good time when I run into this channel. Gotta be scary for drummers, but I'm not, maybe that's it!

Wow. It was only after reading comments on this post until that I remembered WHY I was more than happy to leave Reddit behind. Too bad so many of these diseased children moved over here.

It took just one comment: ' What is “4000ac”? ' to start the drool-fest.

Got a neuralink? One word you never wanna hear: 'Oops!'

Yeah! Did that once, many years back. took a couple weeks. Used a ripper program that went out on the net and got all the metadata, saved to a HD (now on the third one). Put the CDs in Logic cases (no-wear), recycled the jewelboxes.

Over time, started to drop album folders into VLC, save the playlists, at ur fingertips.

The year of the four linux desktops, I hope! (I have 3, but two need to go to the landfill).

After the thousands of years of human history I've read about, getting rid of competitors seems to have been the primary concern of most of the ruling classes all over the world. Way back to Ur.

But I'm not in the field. My reasoning for posting this: I see news about PFAs a lot, this was fresh to me and I was glad to hear the news that chemists are at work on the problem (many communities in WA have contaminated water). And simply-enough for 'newbs' to learn from. I don't find a 'technology for experts' 'community' on Lemmy.

Livescience is far from the best source, but I checked that they had a link to the study (Science) in it.

It appears, going by the comments, that others who are not 'in the field' were happy to learn about. It'd be great if more people 'in the field' would post about such discoveries now and then.

The balloon + helium has to be lighter than the (couple of liters of) air it displaces.

He Density (at STP) 0.1786 g/L

The density of air at sea level is about 1.2 g/L

Another interesting factoid about rare elements: Very little nickel is found in the Earth's crust. Most nickel has arrived on Earth from meteors. Usually mixed with iron, which held-back the arrival of the iron-age.
