We live at the bottom of "an Ocean of Air"

The power of the atmosphere is pretty, pretty darn impressive

yet we seem to take it for granted and barely notice it

Of Course, the tanker implosion also demontrates the amazing power of WATER and phase change

Lucas, thanks for the video pick

I like your observation of "tipping point".....

here is another example of "splosive" phase change

Hi John,

We are all used to the standard reference of 14.7 psi at sea level, but when you convert that to pounds per sq ft it becomes scary, 2117 pounds for every ft².  Buoyancy is good.

Hi Bud, I stumbled on an interesting comment recently that I had never seen before....

A different way of visualizing the "scale" of One Pascal

One Pascal (one Newton per square meter) is very similar to a dollar bill(or any other US bill)

 

 

Hi Caan,

I hesitate to answer your question because it looks like you were merely trying to post a link to your website. Just in case you were serious...The photo shows the Magdeburg Hemispheres

An Explanation of the "Apparatus" was posted below the photo.... I will repeat it:

http://physics.kenyon.edu/EarlyApparatus/Pneumatics/Magdeburg_Hemis...

another explanation can be found here:

http://en.wikipedia.org/wiki/Magdeburg_hemispheres

Lol not at all john. Just interested in what it was. I have a degree in thermo dynamics and looks simular to a apparatus we worked with back at university.

Hi Caan,

Here is a Link to the Main Page.....

For All sorts of Vintage Instruments and Apparatus

http://physics.kenyon.edu/EarlyApparatus/index.html

and here is a link to a most excellent Physics book from 1875

http://www.unz.org/Pub/GanotA-1875

the Illustrations are outstanding

Hi, Lucas "the Heretic" and "Airtight Sheathing Nut"

I am glad you joined HEP

Yes.... I do like Science Videos

Here is one from the not-so-nutty Professor.... that explains the Tanker Implosion

on a slightly smaller scale

http://www.youtube.com/watch?v=0fy4TLMNb6s

and here is another simple video .... showing similar results ...but different

there is a twist in this video....(the candle)

there is more going on here than just condensation and the atmosphere

Even better (in some ways) than Professor Julius Sumner Miller

Professor Walter Lewin

And Lucas,...BTW (By the Way) you are partially to blame for my curiosity/obsession with Neutral Pressure Planes

It was your questions that sparked the comments By Michael Blasnik in this GBA Blog

I also appreciate the link to the Klote Paper that you dug up for me
