OceanGate Submersible Goes Missing During Titanic Dive
swansont replied to toucana's topic in Engineering
Yes. But as long as the compression of the submersible’s material and water are not the same, the effects won’t cancel. -
OceanGate Submersible Goes Missing During Titanic Dive
swansont replied to toucana's topic in Engineering
Water density increases under pressure. The vessel itself would decrease in volume (bulk modulus isn’t infinite) https://water.lsbu.ac.uk/water/water_density.html -
Too many tangents (bots, trolls and socks, oh my!)
swansont replied to swansont's topic in Forum Announcements
Because all bots use the same IP address? Or that would tell us anything useful? -
Any evidence of this hidden horde of trans athletes that choose not to compete at elite levels? Until last year trans athletes in the US could compete in NCAA sports with no restrictions, AFAICT (testosterone testing was then implemented) Exactly one has won a championship, and that was last year. That’s the extent of college competition that could ascend to the elite level. That’s out of 32 trans athletes competing in college in the US. 15 in high school (2 girls) What does this have to do with trans athletes? i.e. people who are not using performance-enhancing drugs?

When you offer up hypotheticals in response to a request for evidence, it suggests there is no evidence. Quoting someone saying largely the same thing else isn’t evidence. It’s not even a hypothetical. So this is to protect the transgender community? Couldn’t they just choose not to compete
-
How will this handful of participants “set back” women’s sports? We don’t need hypotheticals here - some sports organizations have permitted trans women to compete. Are they winning all the trophies? Are cis women not competing anymore?

OceanGate Submersible Goes Missing During Titanic Dive

I had wondered why they kept referring to the passengers as “mission specialists” https://www.newyorker.com/news/a-reporter-at-large/the-titan-submersible-was-an-accident-waiting-to-happen “Although it is illegal to transport passengers in an unclassed, experimental submersible, “under U.S. regulations, you can kill crew,” McCallum told me. “You do get in a little bit of trouble, in the eyes of the law. But, if you kill a passenger, you’re in big trouble. And so everyone was classified as a ‘mission specialist.’ There were no passengers—the word ‘passenger’ was never used.” No one bought tickets; they contributed an amount of money set by Rush to one of OceanGate’s entities, to fund their own missions.” -
Sure it has. There are no more of them. They are all dead. Thus, they are extinct. Which doesn’t change the fact that there are no more of them. Which really happened. We don’t know who the last of most species are, or when that happened, except for rough estimates, even for lineages that died out. The ones we know are the anomalies, not the norm, and partly because we’re living in a mass extinction event. Their name was not changed on some whim. There are defining characteristics of H. erectus not present in later species. Your argument is like saying red is blue, because we can’t objectively nail down exactly where each color transitions to the next one in the ROY G BIV spectrum.
-
And I debunked the claims in the other thread. The “pressure” includes buying clothes. The number they cite is medical or social transition. They don’t, IIRC, give a number for sex change operations. The citations don’t support your claim.
-
He’s just re-upping his assertion from the thread I linked to above. Failed to provide a citation then.

It can’t be often if it’s a rare occurrence. Trying to create an equivalence of teen transitioning rates with murder rates by calling them rare blatantly ignores the rather large difference in the rates at which they occur. I seem to recall dredging up the numbers for genital surgery for teens in the US in another thread; it’s about 20 per year. Compare with the murder count, which is roughly a thousand times larger. That’s not universally true edit: https://www.scienceforums.net/topic/127240-how-best-to-stop-excluding-trans-kids-from-sports/page/5/#comment-1238814

You said I was Homo erectus That’s not how the classification system works
-
My species is Homo sapiens. Or are the biologists wrong?
-
I think this is the wrong line of questioning. I don’t care what anyone thinks, pertaining to this. It’s not at all uncommon for people to think things that are not true, and that rare occurrences are widespread; we see this all the time these days in politics. I want evidence.

I’d have gone with the little blue pill joke, but are you going to address the point?

Point to a living Homo erectus.

How to Convert Diffusion Rate to Hertz
swansont replied to amy1vaulhausen's topic in Organic Chemistry
A cycle, yes. But you haven’t described a cyclic system. -
Are you having a reading comprehension issue? “Isn’t within the realm of discussion” comes closest, seeing as Tyson has not declared themselves to be transgender. Is it that outrageous to want to discuss facts and actual occurrences, rather than, as I said, a made-up scenario? The latter smacks of a desperate attempt to stir the pot.

It’s covering more distance by a lot. A geostationary orbit is ~35,800 km in altitude (~42,200 km from center) as opposed to the 6400 km radius. As Janus says, that’s 6.6 times further out, so it covers a circumference 6.6 times as big in the same time - it’s moving 6.6 times faster. But its ground speed is basically zero.

How to Convert Diffusion Rate to Hertz
swansont replied to amy1vaulhausen's topic in Organic Chemistry
Frequency is the reciprocal of period. To have a period, it needs to be periodic. Just because there are units of inverse seconds, it doesn’t mean there is a frequency. -
Which of these is the best propulsion for Von Neumann probes?
swansont replied to Michael_123_'s topic in Speculations
It’s likely that the propulsion system, like these probes, has not yet been realized. -

swansont replied to Michael_123_'s topic in Speculations
Vaporizing liquid microthruster https://www.sciencedirect.com/science/article/abs/pii/S0924424799003891 “Experimental testing produced thruster force magnitudes ranging from 0.15 mN to a maximum force output of 0.46 mN” That’s not very much thrust. AFAIK resistojets are used for station-keeping, not propulsion. Why does it have to be a Non Neumann probe? Is that in any way relevant? https://beyondnerva.com/resistojet-electrothermal-thrusters/ -
Is CPT symmetry still valid for macroscopic physics?
swansont replied to Duda Jarek's topic in Physics
The left target gets no light. The target on left was the target on the right before you apply the P transformation. It was absorption. It become emission. -
I know I didn’t make the charges, and reported them to the card issuer. They investigated, and refunded the money. And I said waiter, not bartender. It was at a restaurant. —- “There has still to this day not been a report of a single real-world crime that an RFID blocking product would have stopped.” https://www.digitaltrends.com/cool-tech/are-rfid-blocking-products-worth-your-money-we-asked-an-expert/ —- I just read that zero liability is now US federal law. Not sure when that was enacted. Also, RFID transactions are encrypted, so you’d need to use your skimmed info quickly, or the code wouldn’t be correct. Right. Which is why a method that doesn’t require you to hand over your card to someone was developed.
