Archimede’s principle (English text)

Have you forgotten this?

OK, we take a simple approach, for it seems that too many scientists can’t distinguish between mass and weight, and liquid squeezed when the body (mass) is in water.
Not to mention that ice properties seems forgotten, by them. That is IF they ever learned what the teacher taught when teaching these basic knowledge.
That the Wikepedia and other unauthorized encyclopedias online can not distinguish between mass and weight, is in itself deplorable. The researchers who speaks about a possible climate impact of CO2 may be right that the Arctic ice melt (the later is true. not the former.) is outrageous!

Weight is a commonly used name, but really no physical term. Massa, measured in kilograms, is the amount of matter that a property has. If we consider the same mass on Earth and then on the moon, then the wave will show less ‘weight’ (in reality mass) on the moon. Why?

This is where the weight comes in. Gravity is gravity effects on an object / item. Thus, the weight is a measure of a force. Therefore weight is measured in Newton.
So over to the Archimedes principle: the volume of the fluid squeezed / pushed away by an object / objects, wholly or partially submerged in water corresponds to the part of the subject / object’s volume is immersed in the liquid. For more information see the Encyclopedia Brittanica on the Archimedes principle

So for the most basic knowledge needed. Which also the so Climate scientists should know. (Haven’t they ever seen an ICE-cub melting in a drink glass?) First, may I introduce the concept of density. It doesn’t seem that the so-called. researchers have a idea of what it means for ICEBERGS in water …. I am not here to show the chaotic perceptions of water density as one of our Swedish weatherman managed to mix up … … I just laugh J 😉

Density is a physical quantity that tells a lot about a substance / an object’s density. In the case of water it is not at 0 degrees C but at 4 C as the water has its greatest importance. The density of water varies for different water types and the same mass considering that liquid water, ice and steam. At 4 ° C, water’s density is 1.000 g cm-3. The density of ice is roughly 0.917 g cm-3. Which means that the volume of a ice-‘mass’ is greater than the same volume when the water is melting … So the researchers who discussed this at the Ministerial Conference in Tromsø all seem to be trained in Swedish ‘groundschool’ school the last 30 years!

      Thanks for the nice words.
      Re. History please look at New England Antiquities Research Association (NEARA) is number one for those who are interested in North American History as well as have very good if not the best information to give re. Early European/Norse visitors and settlers in NA. NA history doesn’t start with Columbus. NA-history starts with contacts between more than one native group reaching NA. After several thousand years of at least two groups of Native settlers the NA-history continues with contacts between natives and people from other parts of the world in early days mainly wind-driven to NA from 980’s Europeans who had heard of the land out in the Ocean.

      One of the forgotten history’s most intriguing details can be found from archaeology as well as written sources in Leidarvisir och borgaskipan Probably written by Nicholas Bergthorsson sometimes attributed to Nicholas of Thingeyre. The book was written in mid 1100’s. Please read quick English translation below the swedish translation below:

      ”…Norr om Tyskland ligger Danmark. Oceanen sträcker sig in i den Baltiska sjön, nära Danmark. Sverige ligger öster om Danmark och Norge i norr. Norr of Norge är Finnmarken. Kusten sträcker sig mot nordost och sedan österut tills den når Permia, som tillhör Ryssland. Från Permia finns obygder som sträcker sig norrut ända till Grönland [iej !!!] Bortom Grönland, söderut, finns Helluland och bortanför det Markland, därifrån är det inte långt till Vinland. Vilket somliga tror sträcker sig ända till Afrika. England och Skotland är en ö men är separata kungadömen. Island är en stor ö som ligger norr om Irland……”
      (origin in clerk-Latin early translated into Icelandic)

      ”… North of Germany is Denmark. Ocean extending into the Baltic Sea, near Denmark. Sweden is east of Denmark and Norway is in the north. North of Norway’s Finnmark. Land extends to the northeast and then east until it reaches Permia, which belong to Russia. From Permia are unhabited land extending northwards all the way to Greenland. Beyond Greenland, southward, first Helluland and beyond it Markland, from there it is not far to Vinland. which some believe stretches back to Africa. England and Scotland is an island but is separate kingdoms. Iceland is a large island to the north of Ireland …… ”
