Pacemaker No-No!

So I learned that this is called a Van de Graaff Generator.


It generates very high voltage electricity. 


The guy setting it up asks me:

Do you have a pacemaker?


I respond in the negative and ask what’s the danger zone on this thing.


He says: 

You probably wouldn’t want to get within 10 feet of this!


Good to know. 😉

Interplanetary Travel – Coming Soon

Awesome presentation on Interplanetary Travel by Charlie Kuehmann, VP Materials Engineering at SpaceX and Tesla. 


Interplanetary travel and colonization is one of the most exciting possibilities for mankind.  

 

It’s all just beginning (we’ve only been in orbit for about 50 years). 


One of the keys Charlie mentioned at SpaceX and Telsa is how quickly we learn. 


It’s okay to fail, as long as we learn quickly and progress from it.  


The progress with reusable rockets at SpaceX is impressive. 


Can’t wait for more to come soon.  😉

Beautiful Measurements

This is a beautiful set of nested brass weights from France. 


It dates back to 1852!


The weights range from 1 gram to 500 grams. 


These are weights, but also a form of art. 


It is located at the NIST Museum.


There is something comforting about weights, measures, and standards.

 

It puts an organized construct unto our universe and creates some objective scientific reality to our world.

Prepare To Survive!

Picture from active shooter training today. 


Saw a great (and scary) video on RUN, HIDE, FIGHT (from http://www.readyhoustontx.gov) — link to video is here.


Other take-a-ways:

  • Always have a plan A, B, and C. 
  • If you can’t run or hide, fight with everything at your disposal–engage and neutralize the shooter!
  • Survive, you’re not done until your done!


Please G-d, we should never have to deal with the horror of this, but it’s good to learn to be always ready. 😉

Cool Atom Puzzle

Thought this was a pretty stunning puzzle of The Atom


With sections for: composition, atomic model, thermonuclear fusion, periodic table, radioactivity, positron emission tomography, fission of uranium, nuclear reactor, and atomic scientists. 


Wow that’s a lot of information for a Puzzle and one very nicely designed at that. 


Congrats on putting this 1,000 piece beauty together. 


These things make me realize how very much I still have to learn–and in this case, it starts with all these small things. 😉

The Cave Tree

I just think this is such an amazing tree (at work). 

It’s like a cave. 

You go in through the overhanging branches.

And there is a whole seating area with tables, chairs, benches underneath the shade of this lovely tree. 

It’s like the tree was created for giving shade to people. 

What miraculous creations G-d has made for us. 

Shabbat Shalom and Happy Memorial Day Weekend!

Alligator Govie

So this was a little surprising. 


In the courtyard (next to the cafeteria) at work, there is a nice seating area open during the Spring/Summer seasons. 


Pretty trees, flowers, and a pond. 


In the pond, next to the water lilies, there was a what?


Alligator.  


Not a full alligator.


But someone put an alligator’s head in to make things interesting. 


It’s nice at work when people are normal and have a sense of humor. 


An Alligator Govie that’s what it is. 😉
