Poetic justice

A Kentucky teen who sued his school because they required all students to be vaccinated has now been diagnosed as having chicken pox.

A US teenager who took legal action against his school after he was banned for refusing the chickenpox vaccination now has the virus, his lawyer says.

Jerome Kunkel, 18, made headlines last month after he unsuccessfully sued his Kentucky school for barring unimmunised students amid an outbreak.

His lawyer, Christopher Weist, told US media that the teen’s symptoms developed last week.
The student had opposed the vaccine on religious grounds.

His lawsuit argued the vaccine is “immoral, illegal and sinful” and that his rights had been violated.
…

“These are deeply held religious beliefs, they’re sincerely held beliefs,” Mr Wiest said.

Just because a belief is ‘deeply’ and ‘sincerely’ held does not make it reasonable. People can deeply and sincerely believe all manner of absurd and even harmful things.

How train wheels work around corners

Some time ago, I discussed how a car’s differential works to allow the outer and inner wheels to rotate at different speeds when going around curves. Along with that I discussed how trains manage to go around curves even though they do not have differentials and the two wheels rotate at the same rate. Via Mark Frauenfelder, I came across this video demonstrating it even more clearly.

New UN warnings on harm to the planet

Pretty much everyone who follows the news would be aware of the new report released by the United Nations yesterday about the impact of climate change, this one focusing on what is happening to the biodiversity of the planet. You can read the summary of the report here with the full 1,500 page report to be released in September. This news report outlines the major findings.

Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded.
…

Its conclusions are stark. In most major land habitats, from the savannas of Africa to the rain forests of South America, the average abundance of native plant and animal life has fallen by 20 percent or more, mainly over the past century. With the human population passing 7 billion, activities like farming, logging, poaching, fishing and mining are altering the natural world at a rate “unprecedented in human history.”

At the same time, a new threat has emerged: Global warming has become a major driver of wildlife decline, the assessment found, by shifting or shrinking the local climates that many mammals, birds, insects, fish and plants evolved to survive in. When combined with the other ways humans are damaging the environment, climate change is now pushing a growing number of species, such as the Bengal tiger, closer to extinction.
…

Scientists have cataloged only a fraction of living creatures, some 1.3 million; the report estimates there may be as many as 8 million plant and animal species on the planet, most of them insects. Since 1500, at least 680 species have blinked out of existence, including the Pinta giant tortoise of the Galápagos Islands and the Guam flying fox.

Though outside experts cautioned it could be difficult to make precise forecasts, the report warns of a looming extinction crisis, with extinction rates currently tens to hundreds of times higher than they have been in the past 10 million years.

Let’s give Occupy Wall Street and young people the props they deserve

In September 2011, hundreds of protesters known as the Occupy Wall Street movement took over Zucotti Park in downtown Manhattan. It gave birth to the powerful and memorable “We Are the 99%” slogan that so succinctly and yet accurately captured the huge and growing income and wealth divide in the US. Emily Stewart looks at what that movement spawned. (Link thanks to Cory Doctorow.)

Carnivorous plants

There is something fascinatingly contradictory about carnivorous plants. This close up video by the BBC shows how one of them, the Venus Flytrap, works. I have to admit, I was fascinated to learn how the plant captures its prey but saddened by the sight of hapless flies succumbing to its wiles.

A poignant story

I have just finished reading How to Hide an Empire by historian Daniel Immerwahr. It is an excellent book about the complex relationship of the US with the concept of empire and the great lengths it has gone to hide the fact that it is an imperial power. In the early part (p. 56-58) he recounts a poignant story. He tells it so well that to summarize and paraphrase it would be to do a disservice to the story so I give it below.

He sets it up by saying that industrialized agricultural practices had greatly depleted the soil and up to the beginning of the 20th century, the main sources of fertilizer to revive soils were natural sources that were mined from rocky islands in the Pacific ocean that were made of out of hardened bird droppings called guano.

The far side of the moon

While spacecraft have sent back images of the far side of the Moon, until that was possible we could only see one side of it. Wayne Schlingman explains why that was.

Now the Moon takes one trip around the Earth in the same amount of time it takes to make one rotation around its own axis: about 28 days. From Earth, we always see the same face of the Moon; from the Moon, the Earth stands still in the sky.
…

All sides of the moon experience night and day just like we do here on Earth. All sides have equal amounts of day and night over the course of a single month. A lunar day lasts about two Earth weeks.

Here is a short video.

I wonder if the flat Earthers think that the Moon is flat too. You would think that the fact that we see only one side of the Moon would make a stronger case for the flatness of the Moon than the case they have for the flatness of the Earth.

The Extinction Rebellion protest in London

Over the past nine days, a group known as Extinction Rebellion has been blockading central London to highlight the problem of climate change and to protest lack of action on it. They just ended the protest.

Extinction Rebellion, which has been backed by senior academics, politicians and scientists during nine days of peaceful mass civil disobedience, said it would leave its remaining blockades, but added: “The world has changed … A space for truth-telling has been opened up.

“Now it is time to bring this telling of the truth to communities around London, the regions and nations of the UK, and internationally. In this age of misinformation, there is power in telling the truth.”

The group said it would like to “thank Londoners for opening their hearts and demonstrating their willingness to act on that truth”.

The statement added: “We know we have disrupted your lives. We do not do this lightly. We only do this because this is an emergency.”

The activists said protesters had “taken to the streets and raised the alarm” in more than 80 cities in 33 countries. “People are talking about the climate and ecological emergency in ways that we never imagined,” they said.

The US is a great country in which to be a conman

If I were a conman, the US is definitely the country in which to try my luck. It has plenty of gullible and fearful people who have lots of disposable income and are easy prey for any smooth-talking huckster. The only question is what kind of scam one should pull. Religion is of course an obvious one. It does not have to be even Christian which is a crowded field. You can claim to be some kind of vaguely spiritual eastern mystic, something that appeals to a certain kind of disenchanted person.

How can this be allowed?

A church is offering a ‘miracle cure’ that consists of drinking a solution containing bleach.

A group calling itself Genesis II Church of Health and Healing plans to convene at a hotel resort in Washington state on Saturday to promote a “miracle cure” that claims to cure 95% of all diseases in the world by making adults and children, including infants, drink industrial bleach.
…

The “church” is asking attendants of the meeting to “donate” $450 each, or $800 per couple, in exchange for receiving membership to the organization as well as packages of the bleach, which they call “sacraments”. The chemical is referred to as MMS, or “miracle mineral solution or supplement”, and participants are promised they will acquire “the knowledge to help heal many people of this world’s terrible diseases”.
