A Drop in a Vacuum


Some curious individual wondered if the effect of drop of liquid landing on a body of liquid is different in a vacuum than it is at one atmosphere.

 Here's the effect we're familiar with.

Here is a video of of a drop in a vacuum.

 I'm unclear on the physics, but it seems that when the friction between the liquid and air is eliminated, all the energy is absorbed efficiently into the liquid...or something.

I lost the contents of the article, but I remember that what was learned in the experiment had a practical application, which, unfortunately, I can't remember.

Akropolis by Leo von Klenze


The Acropolis today.





Nana Mouskouri - Gloria Eterna




I found a rough translation.


Wherever we go
We keep memories
Athens and Rome
We’re looking for you still
White columns
Black centuries
Heavy years
In the world that we were alone


Hates factions
The Troyes fall
And you Babylon
A hollow drop
All pass
Tell me where are they going
Hell is empty
And around us sprout darknesses


Law the law
Terror the terror
And who will agitate
The world’s balance
My God saviour
I took your stars
To light the arrows
Which show your eternal glory

W.M.  gave me the tape dispenser she bought at the former 88 Cent Store in Port Angeles, Washington, and which has sat on my father's desk for the past fifty years.
