Vision - colors

This podcast about color is so awesome.




Wish I could have the eyes of a mantis shrimp!  We have only 3 types of cones (photoreceptors) for color vision, they have SIXTEEN!  I always feel like there must be colors that I can't see and wonder what they would look like.  I will be coloring a picture and looking around for different colors to use and I just can't find them and I realize that's all that I can see.

Brains!

Brain Day at The Leonardo was a blast.  I now have a picture of me holding a real human brain- woohoo!

Here is a pretty good visual to show what gap junctions and desmosomes are.  The heart has both.

Spelunking aka Caving near Rock Canyon

There are a few small caves around the Rock Canyon area.  One is right next to the trail on the north side of the canyon.  But on Thursday, a friend of mine took me to see a much less-well-known gem.


Here you can see our meanderings...we took the, umm... "scenic route" to finding the cave.  By that I mean, we went straight up the mountain and across a couple ravines before we finally gave up and headed back down, at which point we found the cave maybe 30 meters from where we started.

Fall colors in March?

Lichens!


As we are coming down...oh THERE it is!



The entrance

Tight squeeze


I'm actually proud of myself.  I am a bit claustrophobic and I was worried that I would get in there or half-way in and have a freak-out.  Almost backed out but pep-talked myself, "you can do hard things...it will be worth it."  I took a deep breath and closed my eyes and quickly shimmied myself inside.  The payoff was immediate and well worth pushing through my fear.  These pictures don't come close to doing it justice because they were taken using an iPod and a flashlight. lol
Opens up big enough to stand

Tiny stalactites

Glassy yellow deposits on the wall - minerals? Bacteria excrement?

Coming out took a lot more wiggling, but was less scary than going in. :P
 This cave looked natural except the back ended so abruptly I wonder if it had been dug out at least partly.  Really not sure.  But it was very cool.

Einstein and Pie - I mean Pi


Today is a very special day for two reasons - Albert Einstein, and Pi!
Albert Einstein was born on March 14, 1879.


And today's date is the first three digits of Pi -  3.14 which are pretty much the only digits the typical person knows.  Pi is an irrational number, so the digits are infinite and non-repeating.

The best Pi ever... today I'm going to listen to this song, eat a piece of pie, and solve the area of a circle all at the same time. ;)


My favorite Einstein quotes:
"The problems that exist in the world today cannot be solved by the level of thinking that created them."

"Whoever undertakes to set himself up as judge in the field of truth and  knowledge is shipwrecked by the laughter of the Gods."

"The only source of knowledge is experience."

"It's not that I'm so smart, it's just that I stay with problems longer."

"If we knew what it was we were doing, it would not be called research, would it?"

Lastly, my personal and blog motto:

Videos for Einstein's Theory of Relativity





Happy Pi Day - go eat some pie!
