Have you heard of Nicolas Bourbaki? I hadn’t but David Gunderman writes that “he made fundamental contributions to important mathematical fields such as set theory and functional analysis.” But the problem is that he never existed. So what happened?
He first appeared in 1934 in Paris.

Coincidences abound. A couple of weeks I was talking about Jonathan Miller and the next day I learned that he had died. Then just a few of days ago, I mentioned Alan Keyes’s name because he was the source of the so-called ‘crazification factor’, the size of the population that votes on the basis of tribal loyalty over everything else. I casually wondered what had happened to him. He used to constantly run as a Republican for federal elected offices the US senate in 1988, 1992, and 2004, as well as the presidency in 1996, 2000, and 2008. He is a conservative Christian, fiercely anti-abortion and anti-gay and was a birther to boot.

In 2000, there were 28.2 million cases of measles and 535,600 deaths. Thanks to massive efforts and vaccines, those numbers started coming down dramatically but more recently measles cases have risen again around the world. It is reported that in the last year alone, it went from 7.6 million cases of measles and 124,000 deaths in 2017 to 9.8 million cases of measles and 142,000 deaths in 2018, most of them children under the age of five.
It should be noted that it was in 1998 that discredited British physician Andrew Wakefield (who was later stripped of his medical credentials) published his now notorious and later withdrawn paper claiming a vaccine-autism link, that the British Medical Journal editorialized as an “elaborate fraud” and credited an investigative journalist Brian Deer with exposing it.

Scientific American magazine reports that the Global Carbon Project has released a study that has bad news and just a bit of good news.
Global carbon emissions are expected to hit an all-time high in 2019, scientists say, smashing a previous record set in 2018.
…There is some good news. The authors expect a substantial slowdown in worldwide fossil fuels emissions for this year. Emissions from coal, oil and natural gas expanded by about 2% globally in 2018. For all of 2019, they predict an expansion of just 0.6%.
Part of the slowdown can be attributed to declines in coal use in the U.S. and much of Europe, and lower-than-expected growth from other key coal consumers this year.
“We’re estimating a decline of 10% this year” for the U.S., said the Global Carbon Project’s executive director, Pep Canadell, “well above previous decline levels.”
But slowing the growth rate is not enough. We need to lower the rate altogether.
I have had many posts about really awful wealthy people (the Sackler family and Jeffrey Epstein being noted examples) using philanthropy to cover over the stain of their actions and enable them to act like they are pillars of the community. The assumption is that these acts of generosity are after-the-fact attempts at covering up their ill-gotten gains or their evil acts and ingratiating themselves into society.
But Patricia Illingworth, a professor of ethics, writes that the problem is even worse and that the very act of philanthropy may actually give these people a sense that they have the right to behave badly, something she refers to as ‘moral licensing’.

I was intrigued by this news item.
One of President Donald Trump’s most common responses to intelligence briefings is to doubt what he’s being told, former Deputy Director of Intelligence Susan Gordon said Tuesday.
Gordon, an intelligence veteran of more than 30 years, said Monday that Trump had two typical responses to briefings.
“One, ‘I don’t think that’s true,'” Gordon told the Women’s Foreign Policy Group.
“The one is ‘I’m not sure I believe that,'” Gordon continued, “and the other is the second order and third order effects. ‘Why is that true? Why are we there? Why is this what you believe? Why do we do that?’ Those sorts of things.”
The article implied that Trump was asking these questions because he had got information from other sources that he liked and trusted more that went counter what the intelligence briefers were telling him.
In my own teaching of science, I had two goals: (1) to enable students to sufficiently understand (not necessarily believe) the scientific consensus on the topic we were learning so that they could use it to solve problems; and (2) to get in the habit of reflexively asking themselves the questions: What do I believe? Why do I believe it? What is the evidence for it? What is the counter-evidence against it?
I felt that these two things enabled them to function is the world of science as well as building up necessary critical thinking skills that would stand them in good stead in all areas of their lives.
So I cannot fault Trump for asking the intelligence officials such questions. Of course, it is not clear if he was actually seeking information in order to make better judgments or whether he was merely finding a way to reject conclusions he did not find congenial. Given what we know about him, the latter is likely but still the asking of such questions is a good thing.
American football is a brutal game and so it should not be surprising that it occasionally erupts into outright violence. This feature was on display recently when Myles Garrett, a player for the Cleveland Browns, yanked off the helmet of an opposing player and repeatedly beat him on the head with it until he was restrained by other players. As is often the case there were events that led up to this assault but it was still egregious by any standards. In fact, yanking out a player’s helmet can be very dangerous because the neck is violently jerked. He has been suspended indefinitely but it made me wonder at what point this kind of on-field violence moves into a territory where the perpetrator is subject to legal prosecution.

The first three chapters of my latest book are on the Amazon webpage. (Click on the ‘Look inside’ link.) The publisher’s webpage is here and you can also buy it from any major retailer. (Note: This will be the new top post for a while. Later posts are below.)
Pyrex glass dishes have a reputation for being able to withstand extreme temperatures from the very hot to the very cold. Hence I was surprised when someone I know did something that many of us have done without incident. He took a hot Pyrex baking dish from the oven and laid it on top of the rods that surround the burners you find on gas top stoves that keep the pots slightly above the gas outlets for the flame. But this time, the dish shattered into fragments, sending shards in every direction. He was lucky that he did not suffer any cuts from the high-speed bits of glass.
It turns out that this can happen on occasion and this video shows what can happen when a drop of cold water is placed in a hot Pyrex container.
Computer generated graphics now enable some pretty amazing visual effects in films. In particular, it has been able to make animations look extremely lifelike. But interestingly, when it comes to depicting humans, there turns out to be a problematic element. As the animation gets more and more lifelike, audiences respond positively, getting more empathetic and engaged, but once it gets pretty close but is still not perfect, audience approval drops sharply and people tend to see the humans as creepy until the animation reaches close to 100% of being lifelike, as shown in this graph. The dip is known as the ‘uncanny valley’.
