It appears that the ATF rule against pistol braces that is due to go into effect on June 1 does not apply to members of the FPC. I am not sure if this is a nationwide injunction, or just in the Fifth circuit. Read more here.
Two guys in a car that was reportedly stolen in an armed carjacking. The cops do a high risk stop and notice that the driver has a gun in his waistband. They tell him to drop to the ground. He reaches for the gun, gets ventilated, then it turns out that the gun was a toy.
Some say that the cops overreacted, the guy heard “drop” and went to pull the pistol out to drop it on the ground when they were quick to shoot him. I think, “Don’t carjack people at knifepoint and carry a toy gun around in your waistband” What do you think?
Sometimes when you are teaching, you have to simplify a problem so that students can understand the concepts involved. I will explain. When I was a teacher, I was trying to explain to my Honors Class (I think chemistry, might have been physics. It’s been awhile) how to do a unit conversion using a method called dimensional analysis. It’s a pretty common way of solving equations that is used in the physical sciences.
I first learned the dimensional analysis when I was in the Navy at NucField A school and at Nuclear Power School. It’s handy for solving a lot of things. Dimensional analysis is a method for solving various problems that, once mastered, allows for the rapid solution to unit conversions, various physical problems (like Ohm’s law), medication dosage calculations, and more. It reduces calculation errors and is a very handy skill to have. I use this method all the time to calculate drug dosages, and used it as a firefighter to calculate hose pressures and other useful numbers.
I was teaching it to my students by giving the students a list of things I wanted converted from one item to another. The worksheet that I gave them was a list of problems that were easy to solve, but included the following instruction:
Show all of your work, including the proper setup of the dimensional analysis method. Your work is part of your answer, and any problem that does not include the showing of your work in the proper format will be marked as incorrect and will receive no credit.
The questions were things like:
Convert a $5 bill to nickels
How many toes would 22 people have?
How many legs would 123 ants have? (they each have 8 legs)
So one of my students answered:
And promptly got a zero for a grade. Yes, the math was correct, but I wasn’t looking for the mathematical solution, but a solution that showed me that he had mastered the method of dimensional analysis. Anyone with fourth grade understanding of arithmetic can tell you that 22 people have 220 toes. I knew that they could do simple math, because it was a requirement to have already passed Algebra and Geometry as a prerequisite to even be in my class. This was an honors course where students could receive college credit at the end of the course.
It was important that they understood the concept so when we went on to more complicated problems, they would have the skills needed to solve them. It wasn’t about the math of that particular problem, it was about knowing HOW to use dimensional analysis. That way, when you get a problem that goes like:
A sample of calcium nitrate, Ca(NO3)2, with a formula weight of 164 g/mol, has 5.00 x 1027 atoms of oxygen. How many kilograms of Ca(NO3)2 are present?
The problem can be solved without too much difficulty. The easy problems were not a test of math ability, they were a means of learning a new method for applying math skills that the student already has. A “learn to walk before you try to run” sort of thing.
The child’s parent wrote me and demanded that he receive full credit because he got the correct answers. I tried pointing out the instructions and explaining the reasons behind showing your work. No go. The parent argued that “in the real world” no one cares how you got the answers, just that you ended up with the correct answers. I tried pointing out that, this being school, demonstrating that you have mastered the method is more important than getting the correct answer. The parent continued to argue and demanded that the student receive credit. I refused. They even told me that they would get a lawyer involved. I told them “good luck finding anyone that will support you not showing your work on math homework, when the instructions clearly required it.” Then I told them if lawyers were to be involved, I would be happy to give them my attorney’s number, and their attorney could call mine to arrange a meeting. They hung up on me.
So the parents went to the principal. Nope. They went all the way to the school board, to no avail. The parent finally pulled the kid out of my class and put them into a low level environmental science class.
In this case, the parent did the child no favors.
EDIT: I am editing this to give an example of how dimensional analysis works. Here is the example:
Convert 1 week into seconds:
*Terms on the top AND bottom of the equation cancel out, leaving: (1*7*24*60*60s)/1=604,800 s
Sleepy Joe continues to draw down the Strategic Petroleum Reserve in order to keep gas prices down. We are down to 359,000 barrels, which is the lowest it has been since 1983. Two thirds of our reserves are gone. We are almost out of reserves.
Stories abound on so-called “book bans.” The right is pulling books from school libraries because they instruct children on how to perform sex acts upon other children or on adults. It’s a disingenuous argument. Librarians are acting all offended because a school is choosing not to carry books that are inappropriate for children. The books can still be purchased by those who choose to do so. They can still be read, are still being published. They haven’t been banned at all.
Not so with other books. It was just five years ago that the left cheered as Amazon pulled a book from its store. That book, published by Defense Distributed, was the text version of the step files required to 3D print the Liberator pistol. That book was subsequently banned by a US judge. It is no longer published. It can’t be bought. No one can read it, unless they find a bootleg copy from a site like Pirate Bay.
