The interactive calendar ^ (which can also be found through our web site on the QuestX home page) let's you see what is special about *today* or look up other days/ weeks/ months for science, nature, and otter celebrations! ; ) A few days of Note coming up: April 29 ~ National Arbor Day April 24-30 ~ World Immunization Week May 6 ~ Space Day May 14 ~ World Migratory Bird Day May 22 ~ International Day for BioDiversity May 23 ~ World Thinking Day!
Similar to how letters form words, bases form the genetic code that creates genes.
International DNA Day April 25. Today, in 1952, James Watson, Francis Crick, Rosalind Franklin, Maurice Wilkins, et al published papers in Nature (the journal) on the structure of DNA. It is also the day (in 2003) that the Human Genome Project was declared nearly complete and "the remaining tiny gaps [were] considered too costly to fill."
DNA stands for deoxyribonucleic acid. The bases can be thought of like letters in an alphabet; as letters can be combined to create many words, the sequences of bases create the language of the genes.
Happy Earth Day!!! Just in time, we have just posted our first module for the QuestX video series on Youtube!
Our first module is "So what is science?!?" It is an introduction to some common perceptions about science, and a brief introduction into what science is and what it does. The entire Quest team is pretty excited to bring you this first module, and we are especially exited to bring you more, and even better, modules on exciting topics in science and nature in the near future. We will be following up this module with a full cluster of modules (sorry about the jargon---see definitions and how to watch here) on how science works, the scientific method, and distinguishing science from bullsh*t. Enjoy!
Today and this weekend at Quest we are celebrating EarthDay. Go get on google and look up your local EarthDay events, or if you can't find any events listed that way check out your local wildlife, forestry, county extension. or parks services! Many of them have events planned for this weekend!
Or celebrate on your own, enjoying and appreciating our earth.
Still looking for something to do, check these out:
Today we are also releasing the 1st documentary module on the scientific method, "So...what is science?"! Watch for the video upload on on YouTube site on EarthDay! (and we'll post it)
Leonardo daVinci, Notes on the Movement/Physics of Water.
Confluence: (n) a flowing together or meeting of two or more things at a common point.
Leonardo daVinci is confluence personified: an artist, scientist, inventor, engineer, musician, and architect with a constant sense of questing.
Leonardo was fascinated with water, wanting to comprehend it's nature, properties, how it shaped nature, and how to control and use it. Water inspired his art/music, science, sense of wonder, and his urge to invent and engineer.
He often compared the flow of water to the flow of blood, rivers to veins, and used these workings to understand both systems better.
daVinci, Studies of Water Moving, 1508-09.
Leonardo studied and sketched water throughout his life, one of his early sketches shows his study of the Arno River (Italy), including the movement of water. Other sketches and notes show his scientific approach to understanding water.
Leonardo daVinci, 1473, Study of a Tuscan Landscape, Arno River.
Da Vinci mapped water as it impacted people:
(click maps for larger images)
and landscapes:
Many of his inventions and engineering studies dealt with water:
and how we could potentially *capture* it.
My personal favorite?
How could it not be
da Vinci's underwater breathing device?
Do you have a favorite?
Leonardo daVinci also explored expressing music through *capturing* water, here is a peek at the NOVUS build of the water organ designed daVinci (Chuck Zimmerman's YouTube):
A version of the water organ that you can hear *playing*, built by Joaquin Saura following daVinci's sketches, plans and discussion found in the Madrid Codex II at the National Library in Madrid (Joaquin Saura's YouTube).
Leonardo da Vinci also used water to help capture some of his more symbolic and fantastical musings:
Leonardo's Allegory of Bull, Wolf, and Eagle.
Leonardo's sketch Neptune, 1504-05
Da Vinci's association with water is something that I think many of us feel, a connection. I'll leave you with a some final thoughts from da Vinci, 2 quotes:
" Water
is sometimes sharp and sometimes strong, sometimes acid and sometimes
bitter,
sometimes sweet and sometimes thick or thin, sometimes it is
seen bringing hurt or pestilence, sometime health-giving, sometimes
poisonous. It suffers change into as many natures as are the different
places through which it passes. And as the mirror changes with the
colour of its subject,
so it alters with the nature of the place,
becoming noisome, laxative, astringent, sulfurous, salty, incarnadined,
mournful, raging, angry, red, yellow, green, black, blue, greasy, fat or
slim.
Sometimes it starts a conflagration, sometimes it extinguishes
one; is warm and is cold,
carries away or sets down, hollows out or
builds up, tears or establishes, fills or empties,
raises itself or
burrows down, speeds or is still; is the cause at times of life or
death,
or increase or privation, nourishes at times and at others does
the contrary; at times has a tang,
at times is without savor, sometimes
submerging the valleys with great floods.
In time and with water,
everything changes. "

" The body of the earth is of the nature of a fish ...
because it draws water as its breath instead of air. "
