Speech
When did our ancestors begin speaking? Myself, I always think in words. Thinking about how to fix this device, or where is the game lurking or how to exert leadership of a hunting band, or how to chip flint, or how do I fell this tree without dropping on top of my dwelling or how do I get across that river short of swimming it, all these things I think of in words. Raw emotion, love, fear, hatred, awe, does not need words, but thoughts such as “why is this engine running rough” or “How do a fix this bug” I always do in words. I assume most other people do too.
Thinking is our magic wand. Looking at the fossil record we see brain size increasing as time goes on. This was a successful evolutionary strategy that has made homo sapiens master of the planet. Would increasing brain size do us any good without words to put our thoughts into? I always think in words. If I didn’t have words, I could not think. Does this mean that our earliest ancestors could speak too? Without speech would our larger brains do us any good?
This is all pure speculation of course. I am not aware of any evidence one way or the other. And I cannot imagine finding speech in the fossil record.

D-Day
D-day was an incredible Allied achievement that hastened victory over Nazi Germany. American officers were unanimous in their belief that only a huge army, landed as close as possible to the German border, to drive on Berlin, and hang Hitler from a sour apple tree, would bring victory. Americans, backed by a large and loyal population, endless fertile farmlands, plentiful natural resources, and the world’s largest industrial base, felt that this was possible, If German resistance was stiffer than anticipated, it could be crushed by sending more troops and tanks and guns, of which America had a goodly supply.
The Brits, who put up many of the troops for D-day and much of the airpower and shipping and naval support, had been fighting Hitler for five long years. They had learned, first hand and to their sorrow, how effective the German army was. Norway, Dunkirk, Tobruk, and The Blitz were not happy memories for the Brits. They counseled caution and thought the Americans were reckless in their outlook.
By 1944 the Allies had accomplished two major successes, both of which wee absolutely vital to the success of D-day. First they had solved the U-boat problem. In the “happy days” of 1941 and 1942, the U-boats were sinking hundreds of merchantmen every year. But in the winter of 1943 the Allies got their act together and drove the U-boats out of the Atlantic. They had allocated just a few B24 bombers, with extra fuel tanks in their bomb bays, to close the Atlantic air gap, the black pit the merchant seamen called it. The B24’s could supply good air cover to convoys all the way across the Atlantic. And all the destroyers had been equipped with good radar, Talk-Between-Ships (TBS) radio, and High Frequency Direction Finders (Huff-Duff) which gave a vector pointing right at any U-boat that used its radio. And two years experience at sea had trained up the escort vessels to a high pitch of effectiveness. A couple of vicious convoy battles in the winter of 1943 resulted in the Allies sinking more U-boats than the U-boats sank merchant vessels. For the rest of the war U-boat sinkings remained heavy. This victory allowed the Americans to build up a huge army on the British Isles. Had the U-boats sunk half of this traffic on the way across, D-day would have been impossible.
The second victory was the extermination of the Luftwaffe. This was done by the P-51 long range escort fighters that accompanied the bombers all the way to the target and shot down the Luftwaffe fighters that rose to attack the bombers. There is a scene in “The Longest Day” where a Luftwaffe fighter pilot complains that his was the only sortie flown against the Normandy beaches. Had the Luftwaffe been strong, the JU-88’s would have been dropping 500 pound bombs into the open landing craft as they approached the beaches, and on the Allied destroyers. For larger naval targets the Luftwaffe had Fritz-X, an early model smart bomb that had put an American cruiser out of action at Salerno and sunk an Italian battleship in the Mediterranean. But due to the RAF and USAF actions the Luftwaffe no longer had the planes, or the pilots, or the gasoline to oppose the D-day landings.

Peaceably to assemble, and to petition the Government…
For a redress of grievances. First amendment. We are talking about people carrying flags and signs and posters. Marching in daylight, down routes coordinated with local authorities. Singing and chanting. Making speeches. Listening to speeches. Dispersing and going home when the demo is over. That’s peaceable assembly.
Riots are something else. Breaking shop windows, looting, setting fires, throwing stuff at cops. We citizens expect law enforcement to break them up, suppress them. Surround them; arrest a bunch of ‘em. Use fire hoses and tear gas on em. Keep them from destroying our livelihoods. Authorities that permit, or worse encourage, law enforcement to shirk their duty should be turned out of office at the next election. Or impeached immediately.

The Radial Arm Saw (RAS)
Back in the 50’s, when I was a kid, all the other kids’ fathers had shops, in the garage, in the basement, somewhere. And at least half of them had a radial arm saw in their shop. It was clear to all us kids that the RAS was the wave of the future and table saws were for old fuddy-duddies. My father had a table saw, inherited from my grandfather. The radial arm saw remained popular with do-it-yourselfers up thru the 80’s, maybe the 90’s. Then the safety freaks struck. They declared the radial arm saw to be dangerous, that using a standard blade was dangerous, that making rip cuts was even more dangerous, and the blade guard didn’t cover enough of the blade. The wood shop magazines carried the safety freak stories and stopped doing stories about using and buying radial arm saws. Today, in 2020 there are hardly any new ones for sale, and the price of used ones has sunk down to 50-100 bucks. You cannot buy a skilsaw for that little.
Me, I bought a radial arm saw back in the 70’s and I still have it. I never did get a table saw. I still have all my fingers too. Major benefit of the radial arm saw is it saves space in the shop. You can push it up against a wall and it works just fine. The table saw needs clearance all around it to handle big work pieces. The radial arm saw will make all the cuts a table saw can except for one not too important one. It will make all the cuts a chop saw can make and in addition it will rip, which the chop saw will not. You can also use your radial arm saw as a horizontal boring machine, a disc or drum sander, a shaper, a surface planer, and even as a bench grinder to keep your chisels sharp.
You do want to be careful. The tool is dangerous. The blade on a RAS or a table saw will sever any body part that comes in contact with it. I keep my hands three inches away from the blade at all times. If the work piece is too small to allow for three inches clearance, I throw it in the scrap box and find a bigger piece.
When ripping I first tilt the blade guard down on the in feed side to allow just enough room for the work to go into the blade but not any fingers that might be sliding or riding along the top of the work. Then I always set the anti kickback fingers to dig in and prevent the blade from throwing the work back at me. And I use a wooden shop made push stick for that last bit of push right next to the blade. If the piece is too narrow to safely push it thru the blade, I throw it in the scrap box and get a bigger piece. For tricky or difficult rip cuts I will clamp a feather board to the RAS table to keep the work pressed up against the fence.
In short I don’t see the RAS as more dangerous than the table saw. Both machines will take off fingers with the greatest of ease. You just have to be careful using them. Right now, a used RAS can be so cheap that you cannot go wrong buying it. Craigslist is your friend. If you are starting up a wood shop a RAS makes a fine start.

Regulating social media.
Right now anyone with an IQ above room temperature can log on to Facebook or Twitter or U-tube or the rest of them and post any damn thing he pleases. And it goes world wide. A bunch of Islamic terrorists have claimed they were recruited sheerly thru watching terrorist propaganda on Facebook and U-tube.
The owners of the platforms are the only ones who know how to delete posts, cancel log in privileges, and post comments. We have to trust them, or shut their platforms down. I think the platform owners right along have been deleting material that is clearly offensive, pornography, nudity, sex acts, snuff videos, pedophilia, BDSM, Islamic terrorist propaganda, KKK propaganda and worse. They ought to keep on doing it. Maybe step it up some.
Then we come to individual posters who post all sorts of poppycock, anti Semitic, white supremacy, Nazi, alien invasion, and other weirdo ideas. I think maybe we ought to just leave them alone. Much of it is so weird that no body pays it attention. The offensive stuff can be replied to by those who have been offended.
And then we come to posters who are elected officials. Since they got themselves elected they have support from a majority of their constituents. That’s a lot of people who think they are OK. Same goes for opposition politicos from the major parties. As a platform owner, I myself would be extremely reluctant to censor an elected official for fear of offending a lot of people and inviting retaliation. I think the Twitter people are crazy to censor the President of the US. He has brought them all sorts of viewers/readers/tweeters. If Twitter doesn’t like what Trump tweets, surely they can find some anti trump tweeters to respond to the Donald.
If we are really unhappy with the platform owners, then we can get the anti Trust lawyers to break them up. Facebook is clearly a monopoly. We would be better off with two sites competing for viewers/readers/pageviewers.

Steam Engines, beloved in song and story
The earliest steam engines, Tom Thumb is still on display at the Baltimore and Ohio museum. The design is straightforward, firebox on the bottom, a fire tube boiler mounted atop the firebox and a stack on top of the boiler. Flames rose up thru the firetubes, boiled the water, and rose up the stack creating draft to keep the wood fire burning brightly. Just four driving wheels. Tom Thumb never went fast enough to need the steadying effect of pilot wheels. This design was successful and quite a few were built. But the design does not scale well. A bigger locomotive needs a bigger taller boiler and the taller boiler won't fit under bridges.
New design, that lasted until the end of steam, laid the firetube boiler on it's side, placed the firebox at the rear, where the fireman could reach into the tender for wood, or later coal, and the stack at the front. Flames from the firebox were led forward thru the firetubes and then up the stack. Waste steam from the cylinders was vented up the stack to increase the draft and creating that distinctive choo-choo sound. This arrangement needed a pilot truck the carry the weight of cylinders, stack , and the front half of the boiler.
In my childhood all small boys knew that you could tell a passenger locomotive from a freight locomotive by looking at the number of pilot wheels. Freight ran fairly slowly, say 30 mph and a two wheel pilot truck was enough to steady them. Passenger trains reached 100 mph by 1900 and needed much more weight on the pilot truck to lead the locomotive into switches and curves. The extra weight needed four wheels to support it.
The older smaller 19th century engines located the firebox just over the rear set of drivers. This worked, but it limited the width of the firebox to 4 foot, eight and a half inches, the track gauge. Larger locomotives built after 1900 moved the firebox clean aft of the drive wheels and widened it out to 10 feet, the widest it could be without hitting station platforms. And a pair, sometime two pair of trailing wheels were added under the firebox.

Middle school was getting bad back then
I wrote this for Youngest Son back when he was doing middle school some ten years ago. I wonder if things in school are still this bad.
1. Never say the word "gun" (or shoot or fire or kill or bang-bang or...)
2. Never take any thing that looks like, sounds like, or might be accused of being, a gun to school. Same goes for any kind of knife, even a butter knife. Don't bite your food into gun shapes. Don't point a finger, or anything else at anyone. No toy soldiers, no Lego guns, no books about guns or with illustrations of guns, or people carrying guns (cowboy stories, Johnnie Tremain, Last of the Mohigans, anything like that).
3. Never say anything angry about anyone or anything. If something or someone angers you don't say anything about it. Hold it inside yourself until you get home. Never threaten anything.
4. No touching, no hitting, no hugging. Keep your distance.
5. They are always watching you and listening to you. Especially on the bus, at recess and on the Internet.
Forget any of these rules and they will throw you out of school, for good.
School was easier to survive when I was a kid.

Barrows
Barrows are traditional described as grave sites. That U-Tube lecture makes me think that the barrows served other purposes. Tribal gathering places, sacred places where shamans asked the god for good weather, good hunting and good luck. Places where seers predicted the future. We cannot know at this remove in time. I.m thinking those few graves were the graves of a few exceptional individuals, priests, kings, shamans, mighty warriors, buried in the barrow to bring good luck, bring a friendly spirit, and make a sacred place more sacred. We still do this. Look at Westminster where the British bury their kings and scientists and soldiers.

Cops and Courts should handle Campus Sexual Harrassment
Rape is a serious crime. Used to be a death penalty offense. We have backed off on the death penalty, but it is still a serious crime. I don't like students getting judged by a bunch of college admins for serious offenses like rape. That's what we have police and courts for. And American courts are pretty good on due process, far more so than lefty college admins. When someone complains to the college of campus rape or sexual harassment, the college should offer her (or him) a ride to the police station, and a ride back.

The maker was ashamed of his product and failed to put his name on it. It does have "Made in China" stamped in the inside. It's all white, about 3 inches wide by 3 inches high, half round top. If we ever get the stores open again I will look for something better.

Teach the kids the US Constitution
On the other hand they all feared the British would be back for round two. They all knew that none of them were strong enough to stand off the Redcoats single handed. They knew they needed to present a united front to a hostile world. They also knew that the existing Articles of Confederation were not working. The Confederation lacked even the power to levy its own taxes.
So, when the call to a Constitutional Convention went out over George Washington's signature, all the colonies sent a delegation. All the delegations were intent upon setting up a federal government to handle foreign affairs and national defense but not one that took over their jobs back home. Hence a lot of careful language in the Constitution outlining just what powers the new federal government might have, and those powers it would not have.
Kids ought to understand the separation of powers into the three branches of the Federal government. Article 1 creates the Congress to make the laws. Article 2 sets up the Executive branch to execute existing law but without power to make new law. Article 3 sets up the federal courts and defines their jurisdiction. Note that the state courts existing at the time handled ordinary criminal and civil matters and the federal courts were restricted to matters of federal law. They cannot try a defendant for murder, murder is a state crime, not a federal one.
The Constitution had a lot of compromises and on the whole was a very successful document. It still controls the United States today, with a mere 27 amendments over 230 years. Of those 27, ten were applied right after the adoption of the Constitution and should really be considered part of the original deal. That leaves a mere 17 amendments over the course of 230 years, a pretty good record for stability.

Testing Corona virus to death
But on TV I see various talking heads, the network kind and the medical kind and the political kind, calling for more and more testing and claiming that we cannot let people get back to work until we have tested more and more people.
Why? If we are testing all the patients, what good does testing everyone in the country do? Especially when the test is suspicious. Testing comes back positive on a lot of people who are in good health and show no symptoms. The medics all say these individuals are "asymptomatic" which is true but doesn't tell us much. We more practical people might say the test shows a lot of false positives. With such a test, more testing will make the Corona virus epidemic look worse. The political and network talking heads are fine with that, they think news of worse Corona virus infection hurts Trump, and they are all dyed in the wool anti-Trumpers.
Me, I think we need to get the country back to work before we run out of stuff, like food, fuel, clothing, personal protective equipment, prescription drugs, toilet paper and a zillion other things. You can see the shortages in every grocery store, lots of empty shelves.

Consumer Reports is all about foreign cars, Detroit is dead
They wrote 57 pages comparing cars, best cconobox, best minivan, best this, best that, and so forth. Virtually every single car they listed was a foreign car, Japan, Korea, Germany, and others. A few, very few, US cars listed. Chevy scored occasionally, so did Ford. Very occasionally Dodge, Buick, and Cadillac. Poor old Caddy was down to a single listing. But 95% of all the listings were for foreign cars. Better sell your Detroit motor stocks. Detroit is doomed.
One problem Detroit has is brand dilution, Chevy is offering 16 different models, 7 SUV's or SUV wannabe', 4 sedans, 2 hot rods, 2 pickup trucks, and some odd balls. That's too many. Seven of 'em were things I had never heard of or seen before. And I am a car buff and pay attention such things. Average car buyer is less informed than I am. If we have never heard of it, it ain't gonna sell.
One problem is Chevy doesn't advertise on TV anymore. And the car rags like Road and Track, Car and Driver, Motor Trend, and their ilk are dying out.
Another problem is Chevy isn't really serious about the econobox market. The bulk of the cars on the road these days are little cheap econoboxes. Chevy's offerings ain't cheap ($13K and $16 K) for Sonic (Sonic is a hedgehog and Beretta is an Italian handgun) and Spark (Spark suggests electrical trouble). Good names there. Behemoths like GM need to sell into the high volume market. There ain't enough guys with Corvette money to keep GM alive.

Thinking of purchasing your first firearm?
- Always treat every gun as loaded.
- Never point a gun at anything you don’t intend to kill
- Keep your finger off the trigger and outside of the trigger guard until you are ready to fire.
- After picking up a firearm make sure it is unloaded. Always open the chamber and make sure no cartridge is lurking therein.

That digital TV cable is noisy
Closing Northern Vermont University (NVU) Lyndon Campus
Front page, above the fold, story in this weekend’s Caledonian Record. UVM Chancellor Jeb Spaulding called for closing the Lyndon campus (and some other places too) Needless to say the caused a hue and cry from alumni, students, and local business people. All duly reported on in the Record.
As a New Hampshire resident, the doings over the border in Vermont are only of academic interest. But they did publish some figures on NVU employment that makes me wonder. NVU Lyndon has nearly 1000 students. It also has 700 employees. That’s a pretty plump student faculty ratio. Only 43 employees are full time faculty. I have to wonder what the other 657 employees do, other than draw their pay. And, they pay their faculty peanuts. Assistant professors only make $50,518. A full professor makes $66,000. Electrical engineering pays a lot better than that.
Far as I am concerned, a student faculty ratio of 20 is about right. That would be 50 professors. Nobody else on the payroll. The students mow the grass, shovel the snow, sweep the halls, wash the dishes, and do all the janitorial chores. We did this at my old high school; it only took an hour a day of student time. No paper pushers or administrators at all. Faculty does necessary paperwork, mostly grading papers and writing report cards. Unnecessary paperwork (most of it) just goes into file 13.
Let’s see, 50 faculty at $66,000 each a year is $3.3 million. 1000 students paying $ 11,250 tuition is $11.25 million. You would think that they could make ends meet. Maybe even afford a couple of maintenance guys to fix stuff.

"We are NOT running out of food." Say many Web posts.
The medics and the media are all in favor of keeping the country shut down forever, or at least until a vaccine becomes available, which the TV says will take a year, which is forever if you are an empty grocery shelf. Hence the trickle of "We are NOT running out of food" Web posts.
