The goal of this blog is to create a long list of facts that are important, not trivia, and that are known to be true yet are either disputed by large segments of the public or highly surprising or misunderstood by many.
I created a Facebook page for my super facts or Superfactful blog. The purpose of this post is partially to test if my posts here are showing up on my super fact Facebook page, but it is also to invite you all to follow my Superfactful Facebook page if you wish, or my Leonberger book Facebook page, or send me a friend request to my personal Facebook. I am putting the links to all three below.
Note: I just checked and it is showing up on my new Facebook page
This is not one of my super facts posts but I think it is interesting information about a quite frightening insect that I had never heard of before I encountered it- a tarantula hawk encounter.
When my daughter was 5-7 years old, she was part of what you can perhaps call a pre-girl-scout organization. It was called Indian Princesses. It later changed its name to Adventure Princesses. They had meetings where they learned things, and they went camping as a group with their dads or moms. There were bonfires, grilling, nature, fishing, adventures, jumping in mud, riding horses, and staying up late at night.
One time the Indian Princesses went camping in Camp Classen in Oklahoma. Since we live in North Texas it was not far away. One morning, as we were standing there talking and preparing breakfast, we saw a big black insect landing on the ground.
As we looked closer, we saw that it had landed on a Tarantula. It stung the tarantula, which stopped moving. Then it dragged the Tarantula through the grass about 100-150 feet and then under the girls’ bathroom. As we stood around the Tarantula and the big black insect, we saw that the insect had reddish wings and the body shape of a wasp or an ant. We did not know what it was. This was the year 2005 or possibly 2006 and cellphones with internet were not common.
My daughter ran to get her jewelry box from her cabin. When she came back, she handed it to me and said, “Dad put them in here”. Another dad standing nearby started laughing and said, “yes Thomas I want to see you put them in the box.” It was quite lucky that I didn’t because the big black insect with reddish wings was what is called a Tarantula Hawk, a type of wasp, which allegedly has the most painful sting of any insect in the northern hemisphere. There is an insect with a worse sting in South America.
The Tarantula Hawk is a wasp that feeds on nectar but the female Tarantula Hawk stings and kills Tarantulas to feed its larvae. It stings the Tarantula between the legs, paralyzing it, and then drags the prey to a specially prepared burrow, where a single egg is laid on the spider’s abdomen, and the burrow entrance is covered.
According to this article one researcher described the tarantula hawk’s sting this way: “To me, the pain is like an electric wand that hits you, inducing an immediate, excruciating pain that simply shuts down one’s ability to do anything, except, perhaps, scream.
Below is a youTube video about the Tarantula Hawk.
Have you ever encountered a Tarantula Hawk or another scary wasp or insect?
This is not one of the super fact posts. It is just a post related to an interest of mine that is informational. I volunteer for an organization called Citizens Climate Lobby, or CCL. CCL is a bipartisan organization that works with both Democrats and Republicans to create the political will for climate solutions. During the month of August CCL is promoting what is called electrification. Clean energy is taking the world with storm, but energy / electric power is not the only source of carbon emissions / greenhouse gases.
Take for example, transportation. Most cars still use gasoline and to move towards a fossil fuel free future we must move towards using transportation that uses less fossil fuels such as EV cars. We need to electrify transportation. Another aspect of electrification is replacing gas stoves with induction stoves, installing solar panels, as well as lowering the energy use of your house.
At least here in Texas it is quite common to believe that EV cars do not reduce emissions. After all EV cars use electricity from the dirty grid, right? Often this is said to environmentalists and people who care about fossil fuels emissions as if they don’t understand that the electricity for EV cars typically comes from the dirty grid. However, they do know that. In fact, they know a little bit more. EV cars are much more efficient than Internal Combustion Engine cars , or ICE, and therefore the emissions caused by EVs via the electrical grid, even a coal powered grid, is significantly less per mile. In fact, replacing gasoline-powered cars with EVs saves energy, regardless of the energy source used to recharge the EVs. For an ICE 16-25% of the original energy goes to the wheels whereas for an EV 87-91% of the original energy goes to the wheels.
On the other hand, it takes more energy to manufacture an EV battery for an EV car than it does to produce a combustion engine. So, the production of an electric vehicle does emit more carbon than a petrol car. However, the lower emissions resulting from driving an EV means that an electric car quickly pays back its debt, so to speak. It is typically paid back within two years.
According to Hannah Richie at Our World in Data the statistics show that switching from an average ICE to an equally sized EV will save 1.2 tons of carbon emissions per person and year. That is a lot considering that the average carbon footprint per year is 4 tons worldwide and 14.4 tons per year for an American. Hannah Richie at Our World in Data also states that other environmental damages related to EVs such as mining for minerals are less than mining and extraction for fossil fuel cars, and she claims that the price of lithium-ion batteries has fallen by 98% over the last three decades.
EVs are becoming increasingly common. According to Our World in Data in 2022, 88% of all cars sold in Norway were EVs and 54% of all cars in Sweden were EVs. The United States is lagging a bit at 7.5% but there is a tax credit $7,000.00 for new EVs and a $4,000.00 tax credit for buying used EVs. I should add that we have not yet bought an EV because after I took early retirement, I did not need a car. We just share my wife’s hybrid, which we hardly ever drive.
We bought an electric stove, an induction stove, a couple of years ago when our previous stove stopped working. They come with an $840.00 rebate. I’ve read that professional chefs prefer gas stoves. However, our induction stove provides everything we need for our cooking needs and my beer brewing needs and it is easier to clean. If you are a professional chef you may want to be able switch the high heat on and off quicker, but we are not professional chefs even though the food we cook is delicious.
Another downside of an induction stove is that if the power goes out you can’t cook, but that has not been a problem for us. Considering that we get our electricity from a power company, Green Mountain Energy, that utilizes renewable energy, wind and solar, you can claim that our stove is 100% fossil fuel free.
Air source heat pumps, which are the most common type of heat pumps, are a great, energy efficient choice for heating your home and water and as well as being low maintenance, they can help to cut your heating costs and lower your carbon footprint. An air source heat pump absorbs heat from the air outside a building and releases it inside. It uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction.
Air-to-air heat pumps provide hot or cold air directly to rooms. Heat pumps are the main way to phase furnaces but are also typically more efficient than other types of heaters and air conditioners and thus they reduce greenhouse gas emissions. There is an up to $8,000.00 upfront discount for heat pumps and a 30% tax credit up to $2,000.00. I should say we do not have a heat pump.
Another great thing that we have been thinking about but do not have yet is rooftop solar. Rooftop solar power system, or rooftop photo voltaic systems, consist of electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. Residential rooftop solar power systems typically feature a capacity of about 5–20 kilowatts.
The average American household uses 1.2 kilowatts on average. Most rooftop solar systems are connected to the grid and can feed the extra power into the grid for compensation. I should add this is not entirely without difficulty. There are also hybrid systems which include any combination of wind turbines, diesel generators, and batteries for electricity on demand. There is a 30% tax credit for rooftop solar.
Saving energy is not exactly the same thing as electrification but it is a related topic. If you electrify your home and also reduce your energy needs, you are reducing emissions.
A few years ago, we changed the insulation in our house to reduce our energy needs and our electric bill. It made a difference. We also did weatherstripping, installed three pane windows and high security doors, that were well-insulated and reduced heat-loss. We received significant tax credits for doing this. I don’t remember how much, but it was several thousand dollars. I can add that you get a $150 tax credit for a home energy audit.
What do you think about electrification and energy savings?
Do you have additional ideas for electrification and energy savings?
Despite all the news reports about rampant crime, the US violent crime rate has fallen to half of what it was in the early 1990’s.
I’ve known for a while that violent crime in the US has been going down substantially since 1990. However, quite often when I mention this people refuse to believe it. When I visit NextDoor, the hyperlocal social networking service for neighborhoods, I see people complaining about rising crime, and especially rising violent crime. The news media and the newspapers are filled with violent crime stories, murders, mass shootings, assaults, rape, and robberies. It seems to be getting worse and worse. We are living in scary times, aren’t we?
A couple of years ago I bought a book by Steven Pinker with the title The Better Angels of our Nature, why violence has declined, which contradicted the violence is getting worse narrative. In the book he claims that violence is trending down worldwide and that includes US violent crime.
In 1987 I received a Christmas present from the parents of a fellow student whom I had been tutoring. I was an exchange student to the United States from Sweden at the time. The Christmas present in question was the World Almanac of 1987. I loved it and ever since I’ve bought the World Almanac every year. If you open the pages for crime statistics in the United States in the World Almanac you see the same thing, violent crime in the US is declining.
Below is what the World Almanac 2023 says about the violent crime rate per 100,000 residents in the United States (page 114). The data sources were : Federal Bureau of Investigation, U.S. Department of Justice, Uniform Crime Reporting Program, Crime in the United States 2020. I also included property crimes in the last column to show that non-violent crimes have declined as well.
| Year | All violent crime | Murder and nonnegligent manslaughter | Rape | Robbery | Aggravated assault | All property crime (non-violent) |
| 1990 | 729.6 | 9.4 | 41.1 | 256.3 | 422.9 | 5,073.1 |
| 1995 | 684.5 | 8.2 | 37.1 | 220.9 | 418.3 | 4,590.5 |
| 2000 | 506.5 | 5.5 | 32.0 | 145.0 | 324.0 | 3,618.3 |
| 2005 | 469.0 | 5.6 | 31.8 | 140.8 | 290.8 | 3,431.5 |
| 2008 | 458.6 | 5.4 | 29.8 | 145.9 | 277.5 | 3,214.6 |
| 2011 | 387.1 | 4.7 | 27.0 | 113.9 | 241.5 | 2,905.4 |
| 2014 | 361.6 | 4.4 | 26.6 | 101.3 | 229.2 | 2,574.1 |
| 2016 | 386.6 | 5.4 | 30.0 | 102.9 | 248.3 | 2,451.6 |
| 2017 | 383.8 | 5.3 | 30.7 | 98.6 | 249.2 | 2,362.9 |
| 2018 | 370.4 | 5.0 | 31.0 | 86.1 | 248.2 | 2,209.8 |
| 2019 | 368.6 | 5.1 | 31.4 | 81.8 | 250.4 | 2,130.6 |
| 2020 | 387.8 | 6.5 | 27.6 | 73.9 | 279.7 | 1,958.2 |
The graph below is taken from this article from the Pew Research Center tells the same story. The graph. It shows that the US violent crime rate has nearly halved since the 1990’s. There is a slight uptick in crime for the years 2020 and 2021 but according to this PBS article the downward trend has continued in 2022 and 2023.
Since this is a surprising fact that some does not even want to acknowledge (in my experience) I consider this a super fact.
Do you feel it is hard to believe that violent crime in the US has been declining over the last few decades?
This post is not another super fact but a blog note about the blog and a request for opinions. My most recent post included three super facts combined into one post. The three super facts were:
The post became very long. It had more than 2,000 words and several graphs filled with additional text and data. In addition, I rushed the third super fact. The discussion of the third super fact was muddy, incomplete, and it lacked references. Therefore, I deleted the third super fact. I think that was the right thing to do, especially since I had planned a separate super fact entry for it anyway with the title “We are living in relatively peaceful times”. I will write that post for it soon.
The updated post featuring only the two first super facts is called: “Poverty and child mortality has been sharply reduced worldwide”.
However, I’ve realized that some of my other posts have problems as well. The second half of the post titled “Two events may be simultaneous for some but not for others” feature equations and complex reasoning that physics nerds may appreciate but not typical readers. I don’t think I need to delete that section but, in the future, I need separate such sections from the rest and make it clear that I don’t expect readers to read that, well unless they are physics or math nerds, etc.
So, I am wondering what you all think about this and if you have suggestions or opinions on how I can improve my super fact posts. Blog notes are very much welcome.
