Dragging Clouds


Science or Pseudo-Science

I’m not very good at maths. This is odd for I have off-spring who have degrees in Mathematics and Physics. Some part of the genome has passed me by. My old man was quite good at arithmetic. He could add up someone’s milk bill on the fly and get the answer – always erring on the side of the larger amount, I believe.

I only preface this piece in order that no-one says, “This is dead easy, you fool!” (They may say that anyway)

So we have gravity. I understand the Newtonian theory of gravity (the one with the apple). Gravity is directly proportional to the mass of two objects and inversely proportional to the distance between them. Seems fairly straight-forward. Some odd bits arise. When you jump in the air you are attracted to the earth and soon find yourself back where you started. What people find harder to compute is that the earth is also attracted to you – but because the earth is so much more massive than a person, the earth still comes up to meet you - it is just too small to measure.

To be clear, what we observe is the effect of gravity not gravity itself. “In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravity. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with re-normalization in general relativity.” Clear? I thought so!

What science is saying is that we can observe the effects of gravity but we do not really understand how it works. Some science – oh yea!

So, what has this got to do with dragging clouds?

Matter is in three states. Solid (like the Earth), liquid (like the ocean) and gas (like the atmosphere).

So when the solid earth spins on its axis (as it does once in 24 hours) do the ocean and atmosphere follow at the same rate? Common sense and a little bit of science would suggest that the water moves along at a slower rate and the atmosphere at a much slower rate. Imagine it as the solid earth moving and dragging the oceans and air along with it. (Gravity!)

Now what I want to know is: if my theory is correct, what effect does it have on the weather?

When we look at the weather map we see area of high and low pressure. The uneven heating of the earth causes the air to rise (low pressure) in places and fall (high pressure) in other places. This is the main cause of the wind and our ever-changing weather.

But, take the example of a high pressure area centred over the British Isles. In winter this gives us dry and frosty conditions. - in summer dry and warm.

However, the weather map only concerns itself with the pressure. No account is given to the rotation of the earth under the various areas of high or low pressure. Perhaps changes in pressure cancel out the rotational factors or perhaps the rotational factors are so small as to be not very important.

Does the rotation of the earth affect the changes in the weather?

Could someone please explain?

Trump Golf


Commander in Cheat

How Golf explains Trump

Rick Reilly has written this most entertaining book. It’s obstensively about golf. It’s really about politics and Donald Trump.

His thesis is clear: if you cheat at golf you are just a cheat. And the President is a monumental cheater on the golf course.

Most golfers realise that if you take the odd Mulligan along the way it’s not a criminal offence and even your playing partners will not get too upset. All recreational golfers have played with people who simply cannot count their own strokes for toffee. Are they “cheating”? Probably not, they just can’t remember or have a brain-fade. In a competition at your local club these members are well-known and soon find it difficult to find anyone to play with. Problem solved.

Donald Trump is something altogether different.

Rick tell us that at Winged Foot, where Trump is a member, the caddies saw him kick the ball back onto the fairway so often that they took to calling him Pele (the aristocratic Brazilian soccer star).

Trump always tees-off first. (The etiquette is that a coin toss decides the tee order at the first hole and thereafter the winner of the previous hole gains the “honour” at the next hole). If Trump hooks it, he just puts down another ball and counts that as one. He then hops into his cart, tuned to be twice as fast as all the other carts on the course, so he can get off down the fairway and be first to his ball.

Balls hit into the woods or a bunker or in the water appear miraculously on the green (Caddies and Secret Service agents frequently collude to ensure his ball is in the right place).

One player (nameless in this article) even claims he saw Trump play in “invisible” shot. I saw him make a chipping motion from the side of a hill but no ball came up. Then he walked up the hill, stuck his hand in the hole and pulled the ball out. There must have been a ball in his hand the whole time . . . I mean who does that?

Then there is the “Trump Bump” He may shoot a sketchy 77 at noon. On the ride home his score will be a 75, by dinner 72.

According to Trump he has won 18 club championships. This is like an NFL QB winning 18 Super Bowls. On the official rating site where ethics dictates that you post all your scores, Trump has posted just 20 times in 7 years. The result is an astonishing 2.8 handicap. Jack Nicklaus is currently a 3.4.

Trump breaks the cardinal rules of golf. He drives his super-charged cart on to the greens. He doesn’t take off his cap at the end of the round.

The truth is the person in golf Donald Trump cheats the most is himself.

Does any – or all of this matter?

Don’t forget we have had some fairly dodgy individuals inhabit the White House. Forgetting Tricky Dick, Kennedy was a sex-pest and addict, Eisenhower and Roosevelt probably had mistresses. Harding used to hide in a broom cupboard to carry on illicit sex. The list is long and not very edifying.

If Trump chats at golf but is doing a good job, will anyone really care?

We’ll see.
