Element titled albums

Chembark and Carbon based curiosities recently spoke about a connection between music and chemistry (Tom Lehrer and Heavy Metal).

So, there is a connection between music and elements. There are many album with an element title .
There are 'metal element titled albums'.


Palladium by Autopsia

Plutonium by Inca Babies

Or 'two metal elements titled albums'.

Silver & Gold - Neil Young


There are 'non-metal element titled albums'.
Helium by Urban Myth club



Oxygene by Jean Michel Jarre


There are album titles with element symbols as well.
H2O by Hall & Oates

H2SO4 by The Waves

But these are 'compound titled albums' instead of 'element titled albums'.

This raises the question : 'Are there chemical reaction titled albums?'

Chemical reaction by Vodka Collins

Nice try, but this doesn't qualify.

This may qualify.

H to He (Who am the only one) - Van der Graaf Generator

Okay, the sun's conversion of Hydrogen to Helium by nuclear fusion is not a real chemical reaction, but it is a reaction and they use the element symbols. English 70's progressive rock by Peter Hammill et al featuring the fabulous Robert Fripp is nice for a while.

Top 5 molecular model DNA guys

1) The Nobel DNA guys - Francis Crick and James Watson



2) The other Nobel DNA guy - Maurice Wilkins

3) The Z-DNA guy - Alexander Rich

4) The non-Nobel X-ray diffraction DNA guys - Raymond Gosling and Herbert Wilson



5) The almost DNA guy - Linus Pauling
Unfortunately there is no photo of Rosalind Franklin with a molecular model.

Top 5 alcoholic beverage chemists

1) Dmitri Mendeleev
Wrote the dissertation 'On combining alcohol and water'. He discovered that 38% was the perfect strength, giving the most homogeneous mixture. Mendeleev formulated new state standards for the production of vodka. 40% was the vodka standard because spirits were taxed on their strength, resulting in easier calculation.

2) Aeneas Coffey
In 1809 Coffey became surveyor of excise in Ireland, in charge of opreations against illicit distilling. In 1810 Coffey was severly beaten by moonshining countrymen when he tried to close down illegal stills. In 1821 Coffey patented the Coffey still. In 1835 he founded Aeneas Coffey & Sons, the firm still exists under the name John Dore & Co Ltd.

3) Louis Pasteur
Discovered that fermentation is caused by microorganisms while he was trying to sort out the problems of a fermentation process of a distillery. He also discovered that not all yeast is the same, and that not all yeast makes fine beer.

4) Angelo Mariani
Invented Vin Mariani in 1863, bordeaux wine with cocaine and became a wealthy man. Vin Mariani is not commercially available anymore.

5) Chemgeek (Eric W.)

A chemist and a ghost

Is this a chemist?

No, this is Florence Cook (1856-1904), a British medium who held seances in the 1870's. She was able to evoke a spirit. With Florence's gift the spirit was able to materialize. This spirit was made of a mysterious substance ectoplasm. The name of this spirit was Katie King. The biggest advantage of a materialized spirit is the fact that you are able to take pictures of it.


During a show she would disappear behind a curtain where she would make weird sounds. After a while the materialized spirit (who strangely enough looked just like Florence) would enter the room from behind the same curtain.
You may think:'So What? Why this nonsense? Was this Katie King ghost a chemist?'.


No, but there is this picture of Katie King. The spirit has her hands on the shoulder of this man.
The chemist and physicist Sir William Crookes (1832-1919) with impressive moustache and nice beard.


Crookes studied under the legendary August Wilhelm von Hofmann, he did extensive research on spectroscopy and cathode rays and discovered the element Thallium. He was president of the Royal Society. He was knighted in 1897 because of his scientific achievements. So Crookes was far from a second-class scientist.


Crookes investigated several mediums. His collaboration with Cook is the most famous. He attended many seances and made pictures of the Katie King spirit. His believe in such pseudoscience received a lot of criticism from the scientific community.


In order to prove that Florence Cook and Katie King were two different beings he wanted to make a picture that shows both of them. Ohh... the face of the spirit is covered with a blanket, that's a bummer.

Crookes appears in many theosophic writings as well, including Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds.

In this book there is a periodic system with the title : Periodic Law (after Crookes).

Adyarium and Occultum are there as elements and new series of elements, closely related to the rare gasses. They were called meta-element (meta-neon, meta-argon). When Francis Aston discovered isotopes he used Crookes' terminology and called 22Ne meta-neon.

There are still people who believe that Besant et al discovered isotopes because they described 22Ne. A lot of things they wrote about the meta-elements is not consistent with what we now know about isotopes.

Crookes, like others, believed in an elementary unit of matter, called protyle. Leadbeater and Besant studied this as well with their astral vision. Now there are people who say that they discovered quarks.

Adyarium and Occultum

There is medicinal, organic, bio, theoretical, inorganic, astro, green, surface, polymer, petro, analytical, nuclear, computational, photo, organometallic, physical and a lot more chemistry.

There is a another research area: Occult Chemistry. You don't hear much about it nowadays.

A lot of the ludicrous research in this area was done by Charles Webster Leadbeater and Annie Wood (AKA Annie Besant). The work that was done between 1895 and 1933 is described in the book: Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds.

Besant and Leadbeater were important figures in the theosophical society. Besant was a pupil of the notorious Helena Petrovna Hahn (AKA H.P. Blavatsky).

Both Besant and Leadbeater were clairvoyants, and used this gift to examine atoms and molecules. They made drawings of structures of the elements and their compounds.When they were looking at air with their second sight they discovered a new element with an atomic weight of 3 and they called it Occultum. Later they discovered yet another element, Adyarium, with atomic weight 2 (and they knew that is was not deuterium but a real new element.)

Leadbeater and Besant are often called charlatans, but they were not. Their idiocy was sincere.
It would be great if they performed some synthesis.

Incredibly incredible

Angewandte Chemie International Edition wants to convince us of the fact that it is the best journal there is. In the last few issues they inserted a page with shrieking text in the graphical abstracts.
I can’t wait for the next issue to appear. Maybe this blog will inspire them to have an issue with articles by bearded chemists only.

Tongue mystery

Still there is the question: Is it Ehrenfest or Debye? here on the 1927 Solvay conference video made by Irving Langmuir.
Comparing moustaches can give a clue. As Ashutosh said : Debye had a more Charlie Chaplin-like moustache. You can see this clearly on the famous group picture of the conference.

Here is Ehrenfest, from the same picture.
The 2 minutes video Ehrenfest contains several shots of Ehrenfest. Debye is there two or three times, just a brief moment.

Here he is with the Charlie Chaplin moustache again. In this frame his face seems to be a bit narrower.

It makes you wonder: was he was separated at birth from John Cleese.Debye isn't doing a silly walk though.

Here is Ehrenfest with Debye laughing in the background.His head appears to be polymorphous. When laughing his moustache appears to go from the Chaplin conformation into a broad moustache.I tend to believe that the tongue guy is Ehrenfest. Look at the last frame.
And compare it with this shot of Ehrenfest laughing at the camera.
Yeah, it must be Ehrenfest.... Ehhh... When I see the first frame of the 'stick out tongue'-sequence and look at this picture of Debye I'm in doubt again




The tongue guy is just a Ehrenfest-Debye blend separated at birth from John Cleese.

WRONG?

The previous post may contain false information about the identity of the person on the 'tongue picture'. We had a short discussion about it. We compared the moustache of Ehrenfest and Debye around that time and came to the conclusion that the person on the picture might indeed be Ehrenfest as Ashutosh said (and not a chemist). We may have had some false information. (See comments on previous post).

Maybe sorry.

Stolen idea: Separated at birth?

In this post there was a a picture of a (physical) chemist with the question 'Do you recognized the guy?' Ashutosh gave an aswer that provided an idea for this post.


One in ten thousand had two nice nonsense posts called Separated at birth? (All non-nonsense posts are quite nice as well!) So here is my 'Separated at birth?'.
Paul Ehrenfest

Petrus Josephus Wilhelmus Debije (Peter Debeye)

So the guy was Debije (who, later, changed his name to debye). One of the great early Dutch Nobel prize winners (Van 't Hoff, Van der Waals, Lorentz, Zeeman, Kamerlingh-Onnes). This picture is a frame from the video of the famous fifth Solvay conference. Many attendees were or became Nobel prize winners (this conference is probably famous because of the video).

There seems to be a discussion going on in the Netherlands about Debye. He was director of the physics section of the Kaiser Wilhelm Institute (in that time he (co)fouded the Max Plack institue) untill 1939, and it is said he actively participated in the removal of Jews from the German scientific community.

Many things have been said about this period of his career.

'It's a shame he worked for the Nazi's!'
'He had to because of the German laws!'
'He helped Jews (like Lise Meitner) to escape Germany!'
and so on and so on....

I don't know the true story. One thing is clear: he was not a murderer but he was a great chemist. Let those silly Dutch guys have their discussion about whether the 'Debye Institute' must be called 'Former Debeye Institute' as it is done now. I don't care (never been there), I'm sure Debye doesn't care. (who cares when he's dead?)

And now for something completely different... (I already spoke about stamps a while ago.)

I understand that there is a Dutch stamp with Debye on it.

Why is there a Debye stamp from Ghana?
