It is always fun to see how everyday household items work. Very often, these ‘simple’ devices reveal ingenious engineering designs, like in the case of a nice animation of how rotating desktop fan works.
ProPublica has an investigative report that finds that the manufacturers of child car seats give recommendations about the transition to booster seats that run counter to the recommendations of the American Academy of Pediatrics. Why? Because of the obvious reason: they put profits over safety, even when it involves young children.

I like optical illusions but I have to say that my enjoyment has diminished somewhat now that there is always a possibility that it involves computer trickery and not created out of real, physical objects. The illusion below is nice but the fact that it was created by a VFX artist may mean that it is not the real thing.
Chemist Peter Atkins writes that it is only science that can answer real big questions, as opposed to invented ones such as Why are we here? What are the attributes of the soul?.
They are not real questions, because they are not based on evidence. Thus, as there is no evidence for the Universe having a purpose, there is no point in trying to establish its purpose or to explore the consequences of that purported purpose. As there is no evidence for the existence of a soul (except in a metaphorical sense), there is no point in spending time wondering what the properties of that soul might be should the concept ever be substantiated. Most questions of this class are a waste of time; and because they are not open to rational discourse, at worst they are resolved only by resort to the sword, the bomb or the flame.
Sharon Lerner details the story of how the oil company Chevron is using the US legal system to hit back against a US lawyer Steven Donziger who won a big environmental case against them in Ecuador brought by the indigenous people there whose land had been massively contaminated by the oil giant.
LAST AUGUST, DURING the second-hottest year on record, while the fires in the Amazon rainforest were raging, the ice sheet in Greenland was melting, and Greta Thunberg was being greeted by adoring crowds across the U.S., something else happened that was of great relevance to the climate movement: An attorney who has been battling Chevron for more than a decade over environmental devastation in South America was put on house arrest.
Few news outlets covered the detention of Steven Donziger, who won a multibillion-dollar judgment in Ecuador against Chevron over the massive contamination in the Lago Agrio region and has been fighting on behalf of Indigenous people and farmers there for more than 25 years.

A shocking news report reveals that federal authorities have leveled charges about how Charles M. Lieber, the chair of the chemistry department at Harvard University, engaged in extraordinary acts of academic malfeasance of a financial nature.
Court documents allege Mr Lieber, who has worked as the head investigator at the Lieber Research Group at Harvard University, received more than $15m (£11.5m) in grants from the US National Institute of Health and the US Department of Defence.
Recipients of these grants have to disclose any conflicts of interest, including financial support from foreign governments or organisations.
However in 2011, allegedly without Harvard’s knowledge, Mr Lieber joined Wuhan University of Technology in China as a scientist.

This six-part mini-series based on the book by Terry Pratchett and Neil Gaiman is superb. The 1990 book of the same name is very good but this TV adaptation is even better. It definitely benefits from being made into a miniseries that lasted a total of nearly six hours, rather that a shorter feature film. It enabled the screenwriter Gaiman and the director to provide a much richer texture to an already complex story. The series is available on HBO which I do not subscribe to but I happened to be staying at my daughter’s place and they do subscribe so I took the chance to watch it. I can strongly recommend it. In fact, I plan on seeing it again because the dialogue and acting are so good that it is the kind of thing that benefits from a second viewing, where one picks up on gags that one missed the first time around.
The story is based on the impending Armageddon that will climax in a major battle between the forces of Good and Evil that will be triggered by the Antichrist, who is boy named Adam, soon after his 11th birthday. The TV series expands the roles of Aziraphale (an angel) and Crowley (a demon). Aziraphale was the angel guarding the gate of the Garden of Eden who took pity on the banished Adam and Eve and even gave them his flaming sword to protect them from the wild creatures they would encounter in the hostile world outside. Crowley initially appears in the form of the serpent who tempted Eve. The angel and demon are supposed to be on opposite sides in the war but over thousands of years of crossing paths at various major events in human history have developed a sort of friendship that is grudging at first but becomes stronger when they realize that they both do not see the point of destroying the Earth and all its inhabitants and decide to try and thwart the grand plan. This puts them in the bad books of their two organizations, who try to pull them back into line.

I am of the age when many of my contemporaries worry about dementia. This results in them taking steps that they think will lower the probability of that happening, such as exercise and learning new things. There are many articles such as this one that make recommendations to stave off dementia using just lifestyle changes alone. Following all the recommendations can be overwhelming. I don’t know how much they actually help but they are good things to do for their own sake because they enrich life and even if people do them out of a mistaken belief in their neurological efficacy, they are still worthwhile.

Corey S. Powell provides a history of the Hubble-LeMaitre law and the efforts to pin down a precise value of the Hubble constant that plays a significant role in determining not only the age of the universe but also its ultimate fate. Like the age of the Earth, the value of the Hubble constant, and thus the age of the universe, has shifted considerably over time.

When I saw the title of this article that said Reasons not to scoff at ghosts, visions and near-death experiences, I assumed that it was going to make the case for the plausibility of things that I definitely scoff at. But what the author is arguing is that such beliefs can be therapeutic for some people and thus of some value and we should not too quickly move to disabuse people of those beliefs.
