When you could actually make money from alchemy

Hi,
yesterday I wrote about astrology and I also mentioned alchemy so I will continue with that.


So alchemy in reneissance was very real. It was a study with combination of chemistry, physics and medicine. There were two main things that alchemists cared about: Philosopher’s stone and the Elixir of life.

Alchemy was kind of connected to astrology because the known celestial objects for example were connected to various metals.

Sun gold, Moon – silver, Venus – copper, Mercury – mercury :D, Mars – iron, Jupiter – tin, Saturn – lead.

Alchemists were strictly against adding another metal, why? Because they did not have enough planets!

Their quest simply was to take metal and transform it to the best form – gold. It was said that those metals normally “were in season (is this some kind of phrase?)” in Earth’s crust.

There was one way to get gold, Philospher’s stone also called Red lion.

That was hypothetical stone or red dust that if you mix with metal it will create pure gold. If you saw Harry Potter movie, this is used there in first part.

The second thing that was alchemist trying to make was the Elixir of life. Hypothetical liquid which should be able to cure any disease, even deadly one like cancer.

Across centuries people were also trying to find what was called: Emerald tables. Those were tables where all the important stuff for alchemy was hidden. Also as you can see the fourth best metal in the row was mercury. Since mercury is a bit poisonous some people died from it, I believe that it really fascinated people that something so dense is liquid, but I do not get why they had to drink it immediately!

There are two important people in alchemy of reneissance: John Dee and Edward Kelly, I will talk about them some other time though, look forward.

Some elements of periodic table

Hi,
today I am writing from Brazil which is why I had this few day pause from writing. I have got and idea to write about some elements of periodic table so this post will rather be mess of some stuff I found over time, probably a bit related to astronomy.

First of all I will start with one thing that comes to my mind and that is Hydrogen and Helium. Only those two elements in astronomy count as something different than metal.

PeriodicTable.gifThe reason for this is that astronomers wanted to make some difference between the most important elements in universe and the rest and the rest was almost all metal.

Iron will be the next stop for me. Iron is very special because it is the last element which can be created through thermonuclear fusion. Actually star can fuse iron but only to isotope 55 and then the reaction would take energy to fuse any higher so it is the ending point of stars life. Higher elements can be created in supernovas.

Now let me jump right on the end of periodic table. The last known element is Ununoctium. It has proton number 118. He is also the last known noble gas right after Radon but this element with many others is synthetic which means that you can not find him in the nature and is only made in lab.
Once I asked my chemistry teacher where will be next element since Ununoctium marks the end of another period.
Sadly I had to find out by myself. The next one of course will be right under Francium.
But what is more interesting is that element with 121 proton number will have another shell filled, now it will be G shell. This element would also be the first superactinide.
