Math Mystery Book That Is Bilingual

You can solve mysteries with math, and you can do it in either English or Spanish, with One Minute Mysteries – Misterios de un Minuto: Short Mysteries You Solve With Math! – ¡Misterios Cortos que Resuelves con Matemáticas!, by Yoder and Yoder.

The original version of this book was all English, and was a best seller. This new version obviously gives you mucho mucho mas and math to boot.

The One Minute Mysteries series is well known and widely loved, and is recommended by the NSTA.

Have a notebook or a pile of blank paper and some writing instruments handy because you will need them to work out some of these problems.

This is for kids age 10-14, and is a well written, well constructed, well printed resource. I strongly recommend it if your family has young ones around that age, regardless of their math level. Also check out One Minute Mysteries: 65 Short Mysteries You Solve With Science! and One-Minute Mysteries and Brain Teasers: Good Clean Puzzles for Kids of All Ages.

How to get rid of spiders in your house

How do I get rid of the spiders???

We had a wet spring and summer in Minnesotan. This meant that insects did quite well at the start of the season. Spiders mainly eat insects (and each other, of course) so that meant that the first generation of spiders had a higher success rate than usual. After that, the compound interest effect kicked in so now, by the end of the season, it is said that many homes in the Twin Cities and greater Minnesota are loaded with the tiny eight-legged creatures.

Is it bad to have so many spiders? What if a spider bites me???

Keep in mind that the reason there are so many spiders in your house is that Continue reading How to get rid of spiders in your house

Climate and energy are becoming focal points in state political races

Just a pointer to my colleague John Abraham’s current post in The Guardian:

The latest example, Minnesota gubernatorial candidate Rebecca Otto has a strong clean energy proposal

As soon as Donald Trump won the presidential election, people in the US and around the world knew it was terrible news for the environment. Not wanting to believe that he would try to follow through on our worst fears, we held out hope.

Those hopes for a sane US federal government were misplaced. But they are replaced by a new hope – an emerging climate leadership at the state level and a continuation of economic forces that favor clean/renewable energy over dirty fossil fuels. In fact, it appears that some states are relishing the national and international leadership roles that they have undertaken. Support for sensible climate and energy policies is now a topic to run on in elections.

This change has manifested itself in American politics. One such plan stems from my home state, but it exemplifies work in other regions. I live in the state of Minnesota where we are gearing up for a gubernatorial election, which is where this plan comes from.

My state is well known as somewhat progressive, both socially and economically. The progressive policies resulted in a very strong 2007 renewable energy standard, which helped to reduce carbon pollution and create 15,000 jobs.

As an aside, it is really painful for me to…

On that chilling law suit against the environmental groups

… which I’ve posted on before … there are new developments, summarized at Inside Climate News:

Invoking the Racketeer Influenced and Corrupt Organizations Act, or RICO, a federal conspiracy law devised to ensnare mobsters, the suit accuses the organizations, as well as several green campaigners individually and numerous unidentified “co-conspirators,” of running what amounts to a giant racket.

“Maximizing donations, not saving the environment, is Greenpeace’s true objective,” the complaint says. “Its campaigns are consistently based on sensational misinformation untethered to facts or science, but crafted instead to induce strong emotions and, thereby, donations.” Dozens of the group’s campaign emails and tweets, it said, constituted wire fraud.

“As an NGO, that is a deeply chilling argument,” said Carroll Muffett, president of the Center for International Environmental Law (CIEL), which joined eight other groups to file an amici curiae brief supporting a move to dismiss Resolute’s case.

ICN goes on to describe the background and details of the suits. And now, an important appearance before the courts is about to happen.

On Oct. 10, Greenpeace will ask a federal judge in California to dismiss the case. The group submitted a similar motion last year in Georgia, where the suit was originally filed. The Georgia judge later moved the case to California, where two of the defendants are based, saying Resolute had not provided any “factual basis from which to infer that defendants committed fraud or extortion” in Georgia. “Rather, the allegations in the complaint, at best, support the inference that the defendants organized and held a protest in Augusta.”

“It is very alarming that you can have plaintiffs like this, representing corporate interests attacking legitimate critics doing advocacy work by just drafting a complaint, throwing whatever in there, stretching racketeering law and going after constitutionally protected free speech by throwing labels out there basically trying to criminalize legitimate advocacy work,” said Tom Wetterer, Greenpeace’s general counsel.

More Guns Equals More Gun Deaths

And lax legislation and elected representatives who run their elections using money from the gun industry make sure there are PLENTY of guns to go around. People who are running for office who have pro NRA positions and/or take gun money should be drummed out of politics.

The rate of gun ownership in a state predicts the rate of gun deaths in that state.


This works across countries as well.

Once again. Politicians who have voted in favor of NRA policies need to go.

Vote Down The Guns

First a word about our lovely press. If I hear one more reporter grovel and squirm about how we don’t really want to hurt the NRA or take away any gun rights or do anything unreasonable, no, no, we just want to assume there is a solution to the carnage that does not inconvenience any of the gun loving yahoos that watch our networks …. then I’m going to I just don’t know what. Reporters: Please leave open the possibility that a double digit percentage of Americans don’t care one whit how much restrictions there ends up being on guns. We just want the insanity to end, and if that means taking away all the guns, then, whatever. It was not our decision to make guns so available that they can be amassed in sufficient quantities to shoot over five hundred people in one sitting. We want results, we do not care, not one bit, who’s feelings are hurt.

But I digress.

A Response to the Las Vegas Shooting

From Americans for Responsible Solutions. I’m personally not sure about responsible solutions … I tend to read “responsible” as “watered down” when it comes to the gun debate. But, for what it is worth (and it is interesting) here it is:


Framework for Addressing the Loopholes that Led to the Las Vegas Shooting

October 5, 2017

We would support a proposal that would comprehensively address the loopholes that led to the Las Vegas shooting. More specifically, this proposal would include the following components:

1. Register existing bump stocks and other trigger activators under the National Firearms Act (NFA) and prohibit the manufacture, sale and transfer of such devices. Bump-fire devices are just one type of a variety of attachments sold in the United States to increase the rate of fire of semiautomatic firearms to mimic the firepower of a fully automatic machine gun. Such devices do not belong in civilian hands, and the future manufacture, sale and transfer of such devices should be prohibited. However, an unknown number of such weapons have already been manufactured and sold to civilians. In order to address these existing devices, we suggest requiring them to be registered to the current owners under the NFA. The NFA, enacted in 1934, prohibits possession of an NFA weapon — which currently include machine guns, silencers, destructive devices, and certain other highly dangerous firearms– unless it is registered in the person’s name with ATF. As a result, millions of NFA weapons currently exist in civilian hands, yet are rarely used in crime. The Las Vegas shooting is evidence of this fact: no registered machine guns were used in the attack. Yet, the shooter was able to fire very rapidly to kill or injure hundreds in just minutes, due to his use of bump stocks.

Trump Loses Another Fight, or two

The Trump Administration, in the person of Interior Secretary Zinke, tried to eliminate Obama-era limitations on greenhouse gas emissions from the petroleum industry. The Administration tried to use the “Administrative Procedure Act to turn off provisions intended to reduce how much natural gas petroleum drillers could vent or burn on public or tribal lands. This would have been administered via the BLM. The federal government was sued by California, New Mexico, and various environmental groups, and yesterday, the court ruled in favor of the environment.

This is the second loss for Trump and Zinke in the same courtroom.

A third loss came in a Washington court where Trump tried to side step related methane emission restrictions using the EPA. A federal judge also nixed taht.

Cheap Science Books

Two science books cheap (Kindle version, two bucks):

The Male Brain: A Breakthrough Understanding of How Men and Boys Think

Dr. Louann Brizendine, the founder of the first clinic in the country to study gender differences in brain, behavior, and hormones, turns her attention to the male brain, showing how, through every phase of life, the “male reality” is fundamentally different from the female one. Exploring the latest breakthroughs in male psychology and neurology with her trademark accessibility and candor, she reveals that the male brain:

-is a lean, mean, problem-solving machine. Faced with a personal problem, a man will use his analytical brain structures, not his emotional ones, to find a solution.
-thrives under competition, instinctively plays rough and is obsessed with rank and hierarchy.
-has an area for sexual pursuit that is 2.5 times larger than the female brain, consuming him with sexual fantasies about female body parts.
-experiences such a massive increase in testosterone at puberty that he perceive others’ faces to be more aggressive.

The Male Brain finally overturns the stereotypes. Impeccably researched and at the cutting edge of scientific knowledge, this is a book that every man, and especially every woman bedeviled by a man, will need to own.

I’m not endorsing this book, but if you are a student of sex differences you may want to have a look even if you hate it. But also see by the same author: The Female Brain

Unlocking the Past: How Archaeologists Are Rewriting Human History with Ancient DNA

In Unlocking the Past, Martin Jones, a leading expert at the forefront of bioarchaeology—the discipline that gave Michael Crichton the premise for Jurassic Park—explains how this pioneering science is rewriting human history and unlocking stories of the past that could never have been told before. For the first time, the building blocks of ancient life—DNA, proteins, and fats that have long been trapped in fossils and earth and rock—have become widely accessible to science. Working at the cutting edge of genetic and other molecular technologies, researchers have been probing the remains of these ancient biomolecules in human skeletons, sediments and fossilized plants, dinosaur bones, and insects trapped in amber. Their amazing discoveries have influenced the archaeological debate at almost every level and continue to reshape our understanding of the past.

Devising a molecular clock from a certain area of DNA, scientists were able to determine that all humans descend from one common female ancestor, dubbed “Mitochondrial Eve,” who lived around 150,000 years ago. From molecules recovered from grinding stones and potsherds, they reconstructed ancient diets and posited when such practices as dairying and boiling water for cooking began. They have reconstituted the beer left in the burial chamber of pharaohs and know what the Iceman, the 5,000-year-old hunter found in the Alps in the early nineties, ate before his last journey. Conveying both the excitement of innovative research and the sometimes bruising rough-and-tumble of scientific debate, Jones has written a work of profound importance. Unlocking the Past is science at its most engaging.

You need to do this before any upcoming elections. Find out who on the ballot has a record of opposing guns vs. who has a record of supporting guns, and vote against the gun supporters and for the gun opposers.

I made a list of current members of the Minnesota US Congressional delegation, and put it at the top of the post, with relevant information. I also looked some details up from HERE and HERE.

In a recent rating of recent and current members of the Minnesota House delegation, the NRA gave Rick Nolan, Keith Ellison, and Betty McCollum the grade of “F” and none of these three lawmakers have taken money from them.

Collin Peterson took $2,500 bucks from the NRA, Michele Bachmann took $3,500, Erik Paulson took 2,250, John Kline $2,500, and Tim Walz took $2,000. They all got a rating of “A” from the NRA.

Notice that party lines are being crossed here.

During the recent congressional session, Congresspersons Betty McCollum and Keith Ellison supported zero bills that support guns, but have supported 14 gun control bills.

Richard Nolan has supported one gun control bill.

Al Franken has supported two gun control bills.

Amy Klobuchar has supported two gun control bills.

Those are the clear good guys in Congress from Minnesota. But you might ask why the great variation in number of bills?

Congressman Erik Paulsen has supported one gun rights bill and has not supported any gun control bills. Collin Peterson has supported three gun rights bills and zero gun control bills. Tom Emmer has supported zero gun control bills and five gun rights bills. John Kline has supported a whopping nine gun rights bills and zero gun control bills.

Considering Candidates Post Las Vegas Massacre: Rule Out Tim Walz

A man who was not even known as a gun collector amassed an arsenal that all experts agree included illegal fully automatic weapons. He carried out an act of carnage, alone and using only those weapons, that exceeded in casualty count almost every military battle fought in recent decades by American troops, and that equaled or surpassed all but a very small number of terrorist attacks.

He shot five hundred people.

He shot these people, killing nearly 60 of them, with guns he was able to get because he lives in America. In America, the Second Amendment has protected gun ownership for so long and so irrationally that, even though the worst killing machines are sort of, kinda, a little, illegal, you can still get them.

Guns are the only toys protected by a Constitutional amendment. Gun ownership is a deadly pasttime that is protected by Congress. Even though the CDC and other government agencies, and the concomitant experts, believe that guns are a major public health risk, Congress has legislated against the distribution of research funds one might use to study this problem. And, generally, Congress has been the lapdog of the National Rifle Association, which is a lobbyist organization representing gun and ammo manufacturers disguised as an interest group supporting guns as toys for men and women, but mostly men, across the country.

Why Tim Walz Is Not Viable as a DFL Gubernatorial Candidate

First, let me say that I would normally argue that it is too early to make strong statements against a fellow DFLer (Democratic Party) who is running for office. But what happened last night in Las Vegas has changed all that, and I have to speak out, and strongly so. I am very unhappy about this situation. Here’s the story.

As I was poking around to find out how various members of Congress and future candidates for re-election had voted on guns, in pursuit of writing about Las Vegas. I was shocked and deeply disturbed to find that Congressman Tim Walz, who currently represents Minnesota’s 1st District and is now running for the Democratic Party’s endorsement for Governor, is one of those questionable members of Congress. I had seen Walz speak at a recent forum. Members of a gun-control group were there and they asked the first questions. They asked about various bills and they asked about silencers, an issue that has come up recently in the Minnesota legislature.

I was utterly confused by Congressman Walz’s response to these questions. At no point did he lay down a position. He seemed to take more than one position at a time. He mentioned he was a veteran and a hunter several times, but he also mentioned that we have to be sensible about guns. But he wasn’t able to articulate a position that I could understand, and I’ve been following and writing about gun issues for years. I left that forum not knowing what his position on guns was, but feeling like I had been somehow conned. In fact, I felt like I needed a shower after that set of answers, and I honestly can’t explain exactly why. I did check my wallet on the way out the door, though.

Anyway, I have now looked into it. Walz is, essentially, a Republican when it comes to guns. He supports conceal carry. He supported a bill that allowed the registration and position of weapons that are normally illegal, by a privileged group. He supported the ban by Congress of the Washington DC law that included sensible trigger lock provisions, disallowed semiautomatic weapons, and provided for stricter registration He opposed legislation what would limit access to guns by people with questionable mental competence. And, I think he said, silencers should be legal, but again, I’m not sure.

Walz was actually a co-sponser of HR420, the Veterans Heritage Firearms act. This basically allowed veterans or people related to veterans (i.e., a LOT of people) to keep and register firearms that would normally be illegal, as long as they had stolen the gun off a dead enemy. Or otherwise acquired it while “overseas.”

The act of Congress disallowing Washington DC to regulate its own guns was HR 1399 was also co-Sponsored by Walz. Congress allowed DC to continued to disallow sawed off shotguns, but not semiautomatic weapons.

The mental competence law that Walz supported was HR2547. This bill “Prohibits, in any case arising out of the administration of laws and benefits by the Secretary of Veterans Affairs, considering any person who is mentally incapacitated, deemed mentally incompetent, or experiencing an extended loss of consciousness from being considered adjudicated as a mental defective for purposes of the right to receive or transport firearms without the order or finding of a judge, magistrate, or other judicial authority of competent jurisdiction that such person is a danger to himself or herself or others.”

It seems like Walz is especially concerned with protecting and even expanding beyond normal the gun ownership rights of veterans with mental disabilities, which by definition includes a subset of individuals who really should not be walking around with guns that are not even legal for other people to have.

The other Democratic candidates for Minnesota Governor have very different positions. Walz stands out like a sore thumb among his colleagues. Rebecca Otto wants a science based approach. She noted in a statement following the Las Vegas massacre that Congress has essentially illegalized scientific research on guns and gun safety. Clearly, we have made huge strides in automobile safety, and people generally have the right to drive cars, and far far fewer people are killed because of driving today than would otherwise have been possible without sensible science-based policy. We did not need a Constitutional Amendment protecting driving to make this happen. In fact, the Second Amendment damages our nation’s ability to be sensible about gun laws.

Here is, in part, Otto’s statement:

What we are doing with gun safety laws is not working. We must study gun violence as a public health issue just as we did motor vehicle safety and our work to reduce motor vehicle deaths. We need to steep our policies in evidence, not rhetoric. Let’s collect the evidence and let our scientists study the issue.

The NRA has its place, but not at the expense of so many lives. The NRA and their gun lobby stranglehold on D.C. is a perfect example of the Politics of unfettered greed. Time to end the Politics of Greed & return to the Politics of the common good.

Here’s the thing: Even Walz can be seen as advocating a sensible approach, if you stand in the back of the room, plug one ear, and kinda squint while he is talking about guns. But he has never voted for sensible change, and when he tries to advocate a mainstream progressive policy, his tongue gets stuck on his trigger and thing go badly. He is pushing himself as a progressive left of center who won’t move to the right, but he’s been far right on guns all along.

Sorry, Tim.

The Trump White House Rhetoric seems to say: Give up on Puerto Rico

The White House calls the disaster in Puerto Rico a “good news story,” implying that the federal government is doing a great job there.

Meanwhile, Donald Trump put out a tweet today that seems to imply that the US needs to consider whether or not it wants to help Puerto Rico, which, by the way, is actually part of the United States.

Here is the mayor of San Juan, Puerto Rico, responding to some of this:
