The professor was nonplussed when a student asked him to explain the FACT (!!) that all the signatures on the original Declaration of Independence were forged.<br /><br />And there's a bunch of people who maintain that the original moon landing was faked. No, the National inquirer is not a peer-reviewed journal.<br /><br /> <br /> Johnhttps://www.blogger.com/profile/09575837647825433144noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-55708594873337042702015-08-03T12:18:44.490-04:002015-08-03T12:18:44.490-04:00From a pedagogical perspective, one can have an op...From a pedagogical perspective, one can have an opinion on innately subjective issues that can never be wrong. One can also have an opinion on factual issues where the factual issue is unresolved. The latter can change due to factual developments. <br /><br />These students seem confused because one can have an opinion at some point about factual issues, so they conclude they can always legitimately have an opinion on factual issues.<br /><br />Seems like a good thing to work out in middle school grades. Too bad somebody skipped the issue.Brianhttps://www.blogger.com/profile/09301230860904555513noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-50580000448172187902015-08-03T11:03:28.679-04:002015-08-03T11:03:28.679-04:00The thing is, it is a lot easier in life if you ta...The thing is, it is a lot easier in life if you take a more scientific viewpoint, because then you can go "Oh well I was going by old data" and change what you know. That way your ego isn't as involved. Whereas denialists and suchlike their egos are often involved and everything is personal, thus being wrong is unpossible, because that would involve damage to their sense of self and an admission that they might not be wonderful and infallible.guthriehttps://www.blogger.com/profile/17992984293423290387noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-67480668301415486302015-08-03T02:26:03.917-04:002015-08-03T02:26:03.917-04:00When liquid water is cooled in the range 3.98 C ...When liquid water is cooled in the range 3.98 C < T < 100 C, it contracts <br />However, when the temperature is in the range 0 < T < 3.98, and the temperature of the liquid water decreases, the liquid water expands. <br /><br />So the maximum density of liquid water is reached at 3.98 C.<br /><br />Why does this happen? Because at 0C, liquid water can be converted to solid (ice), and it is well known that solid ice is less dense than water at T= 0C. That's why an iceberg (or an ice cube!) floats in liquid water. <br /><br />It's unusual, but not a mystery and not unique.<br /><br /><br /> <br /> dJohnhttps://www.blogger.com/profile/09575837647825433144noreply@blogger.com
