<div class="moz-cite-prefix">John, <br>
<br>
I gave a similar talk last week to my local LOPSA chapter (League
of Professional System Administrators). Here's some suggestions: <br>
<br>
1. NASA: A Years in the LIfe of Earth's CO2: <br>
article on simulation: <a class="moz-txt-link-freetext" href="http://climate.nasa.gov/news/2190/">http://climate.nasa.gov/news/2190/</a><br>
direct link to youtube video:
<a class="moz-txt-link-freetext" href="https://www.youtube.com/watch?v=x1SgmFa0r04">https://www.youtube.com/watch?v=x1SgmFa0r04</a><br>
<br>
2. The Cardioid heart simulation (yes, another heart simulation!)<br>
Here's a good video that explains everything about the simulation
to kids at a 'science on Saturday' event. You might be able to
find shorter clips or images elsewhere, but this video is a good
overview for you to watch if your not familiar with the project.
It has some good information on why we use simulations in the
first place, too. <br>

<br>
3. Videos of molecular simulations are good, since it demonstrates
simulation something that we couldn't otherwise observe. A quick
search on Youtube showed many videos of this. <br>
<br>
4. Nothing visual, but the the recent 'Blizzard of 2015' that
never hit many of the predicted targets of the United States' East
Coast is a perfect example of why we need HPC, and how it's costs
can be justified. Here's what happened. <br>
<br>
Basically, the forecasts predicted that the Mid-Atlantic and New
England regions were going to get hard with snow. In the NJ/NYC
area where I live, they predicted 18"-24" of snow. Not sure what
level of Armageddon was predicted for the areas outside of my news
broadcast area. As a result, states of emergency were declared in
NJ/NYC and the surrounding areas, shutting down EVERYTHING.Let me
re-iterate that: EVERYTHING in the NYC metro area was shut down
This started the evening before the storm was supposed to hit. My
local utility company brought something like 400 line crews in
from the mid-west to help with the after-storm clean up, since it
was predicted that many power lines would come down from the
blizzard. The university where I work, which has over 50,000
students and employs over 10,000, cancelled classes and closed for
business. <br>
<br>
The NYC metro-area is the largest economy in the US, and is
probably bigger than the economy of many countries, and through
the financial center of NYC has a huge effect on the global
economy. <br>
<br>
What happened with the storm? Most of the NJ/NYC area only 1-2
inches of snow, and the 50 MPH winds that were predicted never
happened. In fact my area got in increased wind at all. In other
words, it was hardly worth shutting anything down for. Eastern
Long Island and north (Boston, etc.) got hit hard, but the NYC
metro area was hardly touched. <br>
<br>
So, what did this shutdowns cost the businesses and governments
that were supposed to get hit hard? I'd bet the cost in list
income, revenue, overtime for government workers, etc, was in the
billions just in NYC metro alone, not considering Philly, DC, etc.
that might have taken similar actions unnecessarily. How much
would better computers cost that run more accurate simulations to
avoid gaffs like this? Tens of millions of dollars? Hundreds of
millions? Even if it is hundreds of millions, it would still be a
savings for the local governments and businesses when you think
about it. <br>
