Calculus or statistics?

 Just read a post claiming that students need a course in statistics to major in STEM fields. Stem (Science, Technology, Engineering and Mathematics) is a good (abet broad) field in college, it is great for finding a job upon graduation. However, the key field, engineering, demands integral calculus. All the engineering fields, electrical, chemical, mechanical, and civil, demand integral calculus. The class lectures, the homework, the exams, and more are all phrased in calculus and if you don't have calculus you simply don't understand what the professor is talking about. Engineering is the best of the STEM courses, you get to do new design work which is the most fun. You need to take integral calculus freshman year. And that means you took trigonometry in high school, cause you need trig for calculus. I never took a course in statistics and never missed it in 40 years of engineering work.

Admiral Jackie Fisher’s battle cruisers.

Way back when, well before the First World War, Royal Navy admiral Fisher wanted vessels to find the enemy battle fleet at sea.  Battle fleets (maybe a dozen battle ships) had a screen of cruisers to shield them from enemy observation in this age before aircraft.  Since the fleet screen was cruisers, Fisher could not use destroyers for searching; the cruiser screen could easily sink any destroyers that caught up with them.  If he used cruisers, all that would happen is a bunch to ship-to-ship duels between his cruisers and the enemy cruisers and he would not find the enemy battle fleet. 

  So Fisher asked for a ship strong enough to break thru the cruiser screen and fast enough to catch the enemy battle fleet.  The result was a big as a battleship, carried the guns of a battleship, and the turbine engines that were just coming into service. In fact the battle cruisers had everything a battleship had except armor plate.  Their commanders thought they were commanding battleships.

   Come World War 1.  The British had built four of Fisher’s battle cruisers.  They were grouped into a squadron under command of the flamboyant Admiral Beatty.  Beatty wasn’t very bright, he wasn’t an experienced old sea dog; he was a member of parliament.  But, as luck would have it, Beatty encountered the German battle fleet at sea, getting ready for the battle of Jutland.  Beatty failed to get a radio message off giving German position, course, and speed, he failed to order his squadron to turn and run for it.  Instead Beatty ordered his squadron of four battle cruisers to engage the Germans.  With in a few minutes the German battleships sank three out of Beatty’s four battle cruisers, “There seems to be something wrong with our bloody ships today.” Beatty remarked at the time. 

   Meantime the British Grand Fleet, under experienced old sea dog Admiral Jellicoe had put to sea.  Jellicoe knew the North Sea, the tides, the winds, the shoal waters, and the amount to daylight.  Using his knowledge of the sea Jellicoe figured where the Germans were going to go.  He got it right, so right that he was able to cross the German’s Tee, a battle winning maneuver in those days.  One firing pass by the British inflicted so much damage on the Germans that they used a fancy new turning maneuver and left the area.  Jellicoe maneuvered himself and about an hour later managed to cross the German’s Tee a second time, inflicting a lot more damage. 

   Next morning, the British fleet was back at Scapa Flow and reported to London that it was ready for action again.  The German fleet was so shot up that it was not ready to sail again for months.  Both sides claimed victory, but by rights the British won this one. 

The FBI today.

 I read that the FBI has been called into that dreadful 4 victim slaying in Moscow Idaho. I wonder if the FBI can still investigate crimes. Does raiding former presidents and other Republicans make good training for finding evidence of crime?

What are we giving Ukraine that costs $40 billion??

 Biden is asking for $37 billion or perhaps $40 billion in military aide to Ukraine.  The TV has mentioned both numbers today.  Take your pick. 

Question: what are we giving Ukraine that costs $37 or $40 billion dollars?  They could buy a new US aircraft carrier for $13 and a skosh billion.  They could buy F35 fighters, the most expensive fighter ever made, for $100 million apiece.  A billion gets you 10 F35s.  $40 billion gets you 400 F35’s.  I don’t know what tanks and armored personnel carriers cost put I’ll bet $40 billion would buy a lot of them.  I suppose Patriot SAM systems, missiles, tracked launcher with a radar on board could be pricey, but I don’t know just how pricey. 

Anyhow, I would like a list of what we are giving Ukraine, and the list price of each item.

American weapons are very expensive what with the services gold plating the specifications, and the Pentagon bureaucrats drowning the contractors in paperwork.  I used to work for a defense contractor, Raytheon.  They had a big two story building out in Wayland Massachusetts.  On the ground floor they had engineering, stockrooms, labs, and shops, all stuff that actually made the product.  Upstairs, just as big as downstairs, were all paper pushers who kept the bureaucrats off Raytheon’s case by filing all the paperwork on time.    

Trump is running.

 As expected, Trump declared he is running for President yesterday. A lot of people like Trump and will vote for him. Trump can fill up a sports stadium with supporters for a campaign speech. While president last time Trump got GNP growth up to 3+ % from Obama's miserable 1%. He built the border fence. He got Kim Jong what's-his-face to stop launching missiles. He got the stock markets up.
On the other hand, there are a lot of people who detest Trump. Democrats, bureaucrats, newsies, are leading anti Trump voices. I have no idea how Trump's candidacy will worth this time. Certainly DeSantos from Florida looks good.

 It snowed up in the notch last night.  First snow of the winter.  Not much, only 1/4 inch.  Enough to turn the grass and the cars white, not enough to make the roads white.

Thor: Love and Thunder.

It's a new 2022 Marvel super hero movie. It does have Chris Hemsworth as Thor, and Natalie Portman but that is about all that's familiar to me. Thor enters the flick wearing a bathrobe. There is a weirdo old man trying to kill every one. It ain't what I think of as a Marvel Thor movie. It is only mildly interesting. I got it from Netflix.
