Both are important

Close. To be a good analogy, their captain would have needed to deliberately steer at the iceberg and he'd need to know that there was a small balloon ready to lift him clear of the carnage. Meanwhile, while some of the crew continued to serve desserts, others would start a panic about a non existent fire in the engine rooms.

Is this a homework question?

When he wrote it, there was widespread- almost universal- acceptance of an alternative "unnatural" version. The word "environmental" has connotations these days which would make the phrase "Environmental Selection" ambiguous. (Does it only select for Green party activists?) I don't see it as doing any harm to remember the Origins of the phrase (pun intended)

If God can only create good and God created man, then man is good. And yet man creates things that are not good. So you are wrong.

Not all of us do. http://www.californiaindianeducation.org/science_lab/indian_stars.html And the reason that different nations of people grouped the stars differently is that the groupings are arbitrary. Constellations are pretty much meaningless.

You would need to put it somewhere warm. Copper chloride is hygroscopic.

What happens with radioactive decay in molecules?
John Cuthber replied to Nod2003's topic in Physics
In a crystalline solid like Ra3N2 it's also probable that you will end up with crystal defects. https://en.wikipedia.org/wiki/Crystallographic_defect and also the electrons, kicked out of the way by the reaction may fall back into place and emit light. Some luminous paints worked on that basis. You can also get electrons "stuck" in a crystal https://en.wikipedia.org/wiki/F-center -
Voluntary Blurry Vision?
John Cuthber replied to Voluntary Blurry Vision's topic in Anatomy, Physiology and Neuroscience
If the focal point wasn't in the plane of the book, the image would be blurred. Magic eye pictures rely on shifts of convergence, rather than shifts of focus. -
They will ignore the emails issue until the cows come home. But if their tax bills go up, he's toast.

Trump's supporters didn't care that he's racist, His misogyny passed them by They put up with his dishonesty. The fact that he was elected on the back of Russian involvement is OK by them. They will accept that the economic damage of his wall was somehow the fault of Obama, or the Mexicans or whatever. In April, the end of year tax demands will arrive. They will see that he lied about cutting their taxes and his popularity will fall to somewhere between that of Hitler and dysentery.

And rationality is founded on evidence so please provide evidence supporting your earlier claim.

Kind of guy who listens to indie rock - what does that mean?
John Cuthber replied to Alfred001's topic in The Lounge
Very little. If it had a proper meaning, you wouldn't need to ask. -
Bill Maher Vs Ann Coulter (split from M vc C debunking wall arguments)
John Cuthber replied to Outrider's topic in Politics
Isn't the fundamental difference that, for a living, one tells jokes and the other tells lies? -
adjustment and calibration of electromagnet
John Cuthber replied to bank0066's topic in Classical Physics
I'm not sure what you mean but, if you want to change the pull from an electromagnet it's much easier to change the voltage (or current) than to change the distance. -

Maybe... https://www.nytimes.com/2019/02/01/us/politics/trump-inf-nuclear-treaty.html -
Yes. In the link I posted. No, it's not.

You were born touching genitals... It didn't do any harm.

The Earth is not actually expanding, nor could it ever have done so in the way you are talking about.. Stop ignoring reality.

adjustment and calibration of electromagnet
John Cuthber replied to bank0066's topic in Classical Physics
If you are using a translation table to alter the force on something, it may be easier to use a spring instead of the electromagnet. What are you actually trying to do? Controlling the current is the obvious way to control the force, and I wonder why the OP hasn't chosen it. For a few hundred kilos of force you really don't need superconductors. https://en.wikipedia.org/wiki/Electromagnetic_lock#Electrical_requirements -
I'm fairly sure that I can use an arbitrarily weak magnetic field and still make as powerful a motor as I wish by using lots of turns of thick wire. It would be stupid, but I can do it. And that proves that there's no single answer to the question. If I wanted to get a sensible design for a 10KW permanent magnet motor... I'd look on the web and copy someone else's design. I can buy one with a shipping weight of 31 KG (the first one I found on Google) so the answer must be "Less than 31 Kg".

Thanks. That's clear enough. We know the Earth's not expanding so we know we can discount one of the theories. I suggest you hold a vigil for the lost soul of your idea and then lay it peacefully to rest. It's not coming back.
