Lol 😁
Im on iPad. I hit the circle and no matter where I hit it, it goes green.
Not that I want to down vote anyone, just curious.

What's with the grey circles? Are we not allowed to down vote anyone anymore.

The rocket cabin (a cylinder) is filled with air. Is all the air then suddenly "pushed" to the rear of the rocket due to "bodies that are at rest tend to remain at rest", and a vacuum formed at the front of the rocket because all the air is not in the rear? This all seems counter-intuitive to me.
Just a thought, but If this were true, wouldn't the same thing happen on planes?
I know you said thousands of miles per hour, but wouldn't the same effect happen at slower speeds.

Precisely what else is the WHO good for, then?
Quite a lot.
The WHO has played a leading role in several public health achievements, most notably the eradication of smallpox, the near-eradication of polio, and the development of an Ebola vaccine. Its current priorities include communicable diseases, particularly HIV/AIDS, Ebola, COVID-19, malaria and tuberculosis; non-communicable diseases such as heart disease and cancer; healthy diet, nutrition, and food security; occupational health; and substance abuse.

You seem to be confusing the World Health Organisation for the US Marines.

Why do they need to have a use?
It's their uses that excite me. The advances in tech.
So there's nothing we can do with them, well that's an anti climax.

It's the second case. Elements that aren't stable, but relatively more stable than you would expect for such a heavy element.
But what can we do with them, what uses do they have?

Since element 99—einsteinium—was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is exceptionally radioactive. A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series.

Any thoughts on Ivanka Trumps future in politics. From the little I've seen she seems to be serious about it. Does anyone think she can actually gain enough support to achieve anything?

Why is it not possible to come up with a cure or vaccine for something like Aids with the same speed as the Covid vaccine?
If the world got together and just focused on one disease at a time, could we come find cures for them pretty quickly?
: "could we come find cures", no edit button 😕

Nice, I like it, but there's a big grey circle over the like button. Is this deliberate or is it my computer?
Also, can't sign out and there's no edit button.

An unfair comparison.
This sounds like my job. I'm the poor sod on his feet all day.
But here's the thing, the work I do is enough to support my job only, the office worker on his ass all day supports all our jobs. Not to mention the extra effort they put in while at school/college.
Also, have you ever sat on your ass all day? I'd rather stand up and walk around, much less tiresome.

If minimum wage isn't good enough for them, it isn't good enough for everyone. Don't count on the market fairy to do the right thing.
Note: something went a bit wrong the the quote thingy.
17 hours ago, ScienceNostalgia101 said:EDIT: One thing I neglected to ask in the OP... how strong is the evidence for, or against, the idea that "diluting the labour pool" decreases wages for non-minimum-wage jobs in the first place?
Emphasis mine.
Disagree with this.
Didn't Apple once say that one of the biggest reasons they manufacture in China is because of the volume of workers compared to America for certain jobs?
Expanding the labour pool would more accurate.
Sorry this is two posts, just got back from work. A bit flustered at the moment.

think not everyone is willing to commit to 8 years in university, along with the subsequent "publish or perish" lifestyle to become a scientist.
Agreed.
Not everyone is able to understand science at degree level even if they could commit. The type of science I like, applied science/engineering would be more accurate, would take PhD level science to understand. I could do some basic science if I wanted, but I'd rather read about 6th generation fighter planes instead.
I think the article is a being a little hard, they've got a point, but in today's world it better than "I don't trust science", a worrying trend in some circles I think.

Physicists imagine a day when they will be able to design a clock that's so precise, it will be used to detect subtle disturbances in space-timeor to find the elusive dark matter that tugs on everything yet emits no light. The ticking of this clock will be almost perfect.

It doesn't just pinpoint the page but may show the desired contents on the search. If I put "pounds to dollars" in Google an inputable convertor app will show directly on the page first, then lists other conversion websites. These are just examples of the pernicious takeover of information and services by these companies. I can't even tell what a sponsored ad is anymore on their search pages... this shit runs deep.
Emphasis mine.
f^^king hell StringJunky, I use the conversion and calculator all the time, the dictionary too. This is the first time I've noticed those other sites.
Had no idea they existed, why would I, I mean It's free on the internet, what's the point?
Its just a little thing, but thanks for pointing that out.

Bing, Firefox, DuckDuckGo, plus several dozen more. If google want to remove its search engine from Australia then let them. There's always someone else to fill the void.

Great story about its origins on wiki. I think the moral of this story is that there are no stupid questions, just stupid answers.
The effect is named after Tanzanian Erasto Mpemba. He described it in 1963 in Form 3 of Magamba Secondary School, Tanganyika, when freezing ice cream mix that was hot in cookery classes and noticing that it froze before the cold mix. He later became a student at Mkwawa Secondary (formerly High) School in Iringa. The headmaster invited Dr. Denis Osborne from the University College in Dar es Salaam to give a lecture on physics. After the lecture, Mpemba asked him the question, "If you take two similar containers with equal volumes of water, one at 35 °C (95 °F) and the other at 100 °C (212 °F), and put them into a freezer, the one that started at 100 °C (212 °F) freezes first. Why?", only to be ridiculed by his classmates and teacher. After initial consternation, Osborne experimented on the issue back at his workplace and confirmed Mpemba's finding. They published the results together in 1969, while Mpemba was studying at the College of African Wildlife Management.[9] Mpemba and Osborne describe placing 70 ml (2.5 imp fl oz; 2.4 US fl oz) samples of water in 100 ml (3.5 imp fl oz; 3.4 US fl oz) beakers in the ice box of a domestic refrigerator on a sheet of polystyrene foam. They showed the time for freezing to start was longest with an initial temperature of 25 °C (77 °F) and that it was much less at around 90 °C (194 °F). They ruled out loss of liquid volume by evaporation as a significant factor and the effect of dissolved air. In their setup most heat loss was found to be from the liquid surface.[9]

Yes and no apparently.
This isn't news or a question, I wasn't sure what to do with it so I stuck it here.
Hot water freezing faster than cold water is a 'fact' I've heard several times now. Searched for an answer and found this.
Found it an interesting read, Thought I'd post it.

Because you aren't being intellectually honest with your argument. You've perverted the idea that we should start by believing accusers into "believe them 100% without doubt". Then you and others piled on with anecdotes from the radio where this perverted argument was repeated, claiming it's only what you've heard. It's pretty sick because once again you're making it harder for victims to get justice from a level field.
I have made no perverted argument about any of these things, just been accused. Just because I've heard it doesn't mean I support it. I made a comment in response to other comments, I've since been accused of being some kind of women hating incel who thinks they lie about rape.
You're making outrageous assumptions about me, I find this deeply insulting.
THIS IS NOT MY STANCE.

I find this thread deeply offensive. There seem to be several members who's general feeling about rape is "we have to protect men".
I won't be returning to this abomination of a thread...
I hope you're not referring to me. This is not my stance, nor have I said it is.

Our default position should be to assume they’re telling the truth.
That’s not the same as saying belief should be automatic 100% of the time with zero doubt whatsoever.
You're accusing me of saying things again. I haven't said this.
I've heard people talk about this and take this position. At no point have claimed this is my position. Not once.

A planet that scientists thought couldn’t exist could change our understanding of how new worlds form.
The planet, officially known as WASP-107b and referred to as a “super-puff”, is far less dense than was previously thought possible, scientists say.

According to whom?
You act like the west is squeaky clean. We're responsible for just as much of the bad things in the world as anyone else.
There are plenty of people who think countries like Britain and America are run by tyrants.
We negotiate with terrorists all the time. The IRA, FARC, Taliban...
