gravity can pull us through the cosmos to where we want to go
zapatos replied to farsideofourmoon's topic in Relativity
We like to say Earthkind, not peoplekind. Hopefully if we ever travel the stars we'll have learned to stop being speciesist. We can't even do that right yet. -
Wood-burning as an alternative to fossil fuels
zapatos replied to ScienceNostalgia101's topic in Chemistry
That's going to be one big-ass lab. -
Sounds similar to not wanting to teach children about contraception due to the concern that it can tempt teens to be sloppy with their behavior, who may act that way on the basis that any sperm will be captured by condoms anyway. 😀 Is there any evidence that American poultry workers are indeed sloppy in their methods, or that any sloppiness translates into poor health outcomes? Yep, that looks pretty damning.

I hear this argument about American food standards versus European food standards often and was wondering if anyone knows if the difference translates into health differences for consumers.

Thanks! I didn't know there was a name for it.

I find this to be true, and I find that both parties are responsible. Some people of science tend to forget how long it took them to get to where they are now. Understanding a concept or readily being able to discern science from pseudoscience is a skill that is developed over many years and with a lot of effort. It is easy to get frustrated with someone who seems oblivious to a concept that to a scientist is so obvious. It is often difficult to determine if someone is closing their ears to science or if they are just not experienced enough yet to process the information they are being given. I find that lay people often respond out of emotion instead of reason, and therefore find people of science to be arrogant. People generally do not like being told that they are wrong, sometimes spectacularly, and that they are often wrong because they were duped. That is tough on the ego. It is easier on the ego to get angry at the person correcting you, than to acknowledge that you were a fool.

Still seems like an unfair statement to me. I'll buy that the Trump voters got what they deserved. Maybe even those who can't be bothered to vote. But what about the rest of us? Sounds like I deserve Donald Trump for making the mistake of choosing to be born in the US instead of Canada (or Italy as the case may be).
-
That statement seems a little unfair. The majority of the US did not vote for Trump. The majority of 'voters' in the US did not vote for Trump. And that is just looking at the US. Surely the people of North Korea don't 'deserve' Kim Jong-un. The list of despots goes on and on.

I think the scientific general consensus is that Sweatman is smart enough to be able to develop excellent pseudoscientific theories which he turns into best sellers. For the layman his ideas seem sound, but to the scientist who actually studies what Sweatman is writing about it is all nonsense. Sweatman develops a plausible scenario (I purposely did not use the word "theory") but is not interested in investigating any of the obvious next steps to support his conjectures. He's not a scientist in these cases; he's a writer. Therefore once the book is done, from his perspective there is nothing left to do. Sweatman is similar to Asimov in that he uses his scientific knowledge to be able to write believable fiction.

Stop putting houses in the middle of fire prone areas. No different than not putting houses in flood plains. -

Fire is good for the ecosystem. -
Ah yes, relativity vs Relativity. Sometimes I'm slow on the uptake. Thanks for the further explanation. 😁

That was very helpful. Thanks!

Does it mean that GPS quits working? If not, what does quit working? Or is it more the case that Relativity will still work fine, but something else will be needed to account for the preferred frame. Similar to how Newtonian physics didn't quit working when Relativity came along and addressed new situations that Newtonian physics didn't address.
-
Would you mind expanding a bit on how physics could be broken by having a preferred frame? Are you saying that losing then assumption of 'no preferred frame' means that certain calculations would no longer work? Or is it more of a case that we would have to rethink our explanation of what the universe looks like. For example, when we discovered that our galaxy wasn't the entire universe, afaik that didn't mean any of our calculations no longer worked, only that we had to change our understanding of the universe and how it worked.

Elephants have about 150,000 muscles in their trunks. They can pick up a peanut with their trunk, shell it, and then blow out the shell before eating the peanut. In American football there is a staff member called the "get-back coach". His job is to make sure the players on the sideline, and especially the head coach, get back behind the line so they don't get a penalty.

Wouldn't the Earth appear curved, even if it were flat?

What makes you think that would be the case? -
Generational craft (split from Terraforming the Solar System)
zapatos replied to Airbrush's topic in Astronomy and Cosmology
Yeah, somebody is always predicting the impending demise of humanity. Barring some extinction level event that had not been identified by Hawking, I'm betting my grandchildren will not be among the last humans. -
I can't make heads or tails of this statement. It takes on the properties of time and is therefore without time?!?! What does that mean? So when I turn off the bedside lamp I suddenly become waves/frequency? We only exist in the fourth dimension? How are you defining "dimension"? Like length/width/height/time? Or like "You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas; you've just crossed over into the Twilight Zone."

And society usually finds an activity that causes harm to be unacceptable.

Was there something you wanted to discuss?

Best of luck! Do you have a plan for identifying when it might be a good idea to cease the experiment if it doesn't work out as you plan?

Depends on a whole host of factors, not the least of which is how much of what you eat and how much you exercise. I suspect exercising every time you eat some sugar is not likely to happen, and the more you ate, the more you'd have to exercise. If you eat sugars frequently throughout the day then your glucose levels will frequently be going up and down which is a risk factor for developing Type 2 diabetes.
