The Moon and Christopher Columbus

No matter when or where one observers a lunar eclipse, it looks like this.  And it seemed obvious to those who thought about it that the cause was the Moon moving into the Earth's shadow

(On May 21st I wrote about solar eclipses)

And since the 3rd century it was known that the Earth was round. Eratosthenes showed how big the Earth was and lunar eclipses confirmed this idea. Consider that only a round Earth will always cast a round shadow.

So in 1492 Christopher Columbus knew how big the Earth was and how far West he had sailed, and that he had failed to reach India. So what did he do? Got a good press agent and sold a story of a short way to India, to gold. He knew he had not reached India and the Indigenous have suffered ever since.

There will be more eclipses in the near future, a couple of total lunar eclipses and then whether I am ready or not a total solar eclipse on April 8, 2024

If you click on show eclipses 2020 to 2029 you will get the dates of all the eclipses and can decide whether you are on holidays to see an eclipse or not!


PS If you read the article about Christopher Columbus, you will learn that he had sailed up and down the Atlantic and almost certainly talked with fishermen. He "knew" what he was doing.

Something to grackle about

I have been learning, maybe even leaning on the great labour-saving device, procrastination. Maybe tomorrow I'll write up part 3 about the Moon and Chris Colon but not tonight.

I had a very pleasant encounter of almost the 3rd kind when I paddled along the shore of Tudhope Park on Wednesday, Enjoy the vibrant "Mayan" colours.

The sequence lasted just over 10 minutes along some 30 - 40m of shoreline. Most enjoyable.

Everything is "Ducky" with the wise old bird

Spring cleaning reached the kayak yesterday, thanks to Elisabeth and Jeromy. So I went out, too, and returned with memories from land and water.

At Leacock on May 15

And again yesterday

And then across at Tudhope - Canada geese last week

And yesterday

I found the lighting unreal - like I was seeing a painting.

There was also a Mallard family. The drake was herding the whole family, Mom, too. This was in contrast with the Leacock family which also had a drake well out of the "picture".

He finally got them all together

Anf peace returned to Mariposa.

Einfuhrung = Introduction

Durham Forest - Oak Ridges Moraine

Wir waren etwas bei "D" in Oak Ridges, quelle für Duffin Creek Ost (rechte Arm)


Canadians are well educated, and understand the law and so have no problems obeying it. Social distancing, wearing a mask, dog on the leash, paying taxes, saying "Sorry, eh!" Wahrscheinlich auswanderer von der Eifel -Ardenne!

Old forest -200 years old - the road-trail-Weg was never built.

Mai Apfel!

And fiddle heads oder Geigerkopf - gebratten in Butter =  lecker -

Und was wir gesucht haben -

White Trillium.

Aber oben ist normal - es gibt doch andere:

Und dann

Und viel mehr, many more variations, Volker!
